Description

{HAIR TRANSPLANTER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mosquito net used for hair transplantation, and more particularly, to a mosquito net configured to minimize a front exposure length of a bristle tuft so as to reduce unnecessary deep incision in a patient's skin.

In general, a mosquito repellent refers to a device used for implanting biological or artificial hair in a region where hair is lost in the case where hair is lost on the human skin due to diseases, accidents, or the like.

Since the hair follicle unit graft is widely used in the past, the hair follicle is separated into follicular units and then inserted into the follicular needle of the mosquito, so that there is little bleeding and scarring, and the direction, angle and density of the hair can be arbitrarily adjusted Since the shape of hair can be maintained naturally after transplantation, it is widely used not only for hair but also for transplantation of eyebrows, whiskers, eyelashes, and pubic hair.

Figures 1 and 2 illustrate, by way of example, the structure of a conventional food mosquito that can be used in such follicular unit grafting. 1 and 2, the eating mosquito includes an outer housing 10 forming a body, a sliding member 20 (inner housing) inserted in the outer housing and moving relative to the housing, A pressing member 30 mounted on the rear end to operate the sliding member 20 and the mandrel 40; a pressing member 30 mounted on the rear end of the pressing member 30, 50). The lifting needle 30 is fixedly attached to the outer housing 10 and the sliding member 20 and the mandrel 40 are connected to the pressing portion 50 in a state of receiving the elastic force of the elastic member 60, 50 to move with respect to the outer housing 10 and the hairpin 30 together. That is, when the user presses the pressing portion 50 of the eating mosquito, the sliding member 20 and the shaft 40 move together with the pressing portion 50 forward relative to the outer housing 10 and the hair- And as a result, the hair removal needle 30 is inserted into the sliding member 20 (inner housing) as shown in Fig. 3 and removed from the patient's skin.

Hair transplantation using such a mosquito is performed by inserting the hair follicle A into the hair follicle 30 and then inserting the hair follicle 30 into the patient's skin as shown in Fig. At this time, the hair follicle A should be deeply positioned inside the hair removal needle 30 so as not to be damaged in the process of inserting the hair removal needle 30 into the skin. If the hair follicle 30 is inserted into the skin while the hair follicle A is exposed to the front of the hair follicle 30, the hair follicle A is inserted into the skin of the patient during the insertion of the hair follicle needle 30 It may be pressed and broken or damaged, resulting in a lowering of the rate of engraftment of the transplanted hair follicle or a severe curl after implantation. Therefore, the conventional mosquito has to be constructed so that the hair follicle 30 is exposed forward for a length longer than the hair follicle A (see x in Fig. 4).

The hair follicles A are attached to the hair follicle 30 by being pulled backward while holding the hair connected to the hair follicle A using a medical instrument such as a forceps. There is a limit in attaching the hair follicle A to the end portion of the sliding member (inner housing) because the front end of the member (inner housing) is formed perpendicular to the hair follicle needle, It has to be exposed for a long time (see Y in Fig. 4).

However, when the floss is exposed to the outside for a long period of time, there is a fear that the flossing of the patient may be performed at a depth greater than the depth required for follicular transplantation in the process of inserting the floss into the patient's skin. It can cause damage such as hemorrhage due to microvascular injury, delayed wound healing, increased chest tissue formation, and folliculitis.

The present invention relates to a mosquito repellent composition for relieving the problems of the above-described conventional mosquito repellent, and a mosquito repellent composition capable of reducing the risk of unnecessarily deep incision on the skin of a patient, The purpose is to provide.

Figs. 5 to 14 illustrate, by way of example, the structure and operating principle of an eating mosquito according to the present invention.

5 to 10, an indoor mosquito according to an embodiment of the present invention includes an outer housing 100, a sliding member 200 (an inner housing) inserted into the outer housing 100, (400) which is inserted into the hair removal needle (300) and can relatively move in the longitudinal direction relative to the hair removal needle (300) And a pushing unit 800 mounted on the sliding member 200 and the shaft 400 to operate the sliding member 200 and the shaft 400. At this time, the sliding member 200 is elastically supported in the backward direction by the first elastic member 600 and the axial shaft 400 can be mounted in a state of being elastically supported in the backward direction by the second elastic member 700 The sliding member 200 is provided with a notch 216 at the front end thereof in the backward direction so that the hair follicle A is moved inward to the inside of the sliding member 200 without interfering with the sliding member 200 So that it can be mounted. That is, the mosquito-based mosquito according to the present invention is characterized in that (i) a notch is formed at the front end of a sliding member (inner housing) surrounding the knife holder, (ii) And is configured to be elastically supported rearwardly through a separate elastic member, instead of being pressed by a mosquito. In the present specification, 'forward' means the direction in which the knife holder 300 is positioned in the food mosquito, and 'rear' means the direction in which the pusher 800 is located in the food mosquito)

The outer housing 100 is a portion forming the outer shape of the eating mosquito, and may be formed of one or a plurality of members. In the embodiment shown in the drawing, a plurality of members (the body 110 and the front cover 120) are assembled to form the outer housing 100 so that the disassembling / assembling of the eating mosquito can be more easily carried out Consists of.

The body 110 may be configured to penetrate the body in the longitudinal direction and receive the sliding member 200 through the through hole. The body 110 may have a concave portion 111 at the outer circumference thereof, So that the operator can easily grasp the eating mosquito.

A coupling portion for coupling the front cover 120 to the body 110 may be formed at the front end of the body 110. For example, the mosquito repellant according to one embodiment of the present invention is configured such that a screw portion 112 is formed on the inner periphery of the front end side of the body portion 110 and the front cover 120 is coupled to the body portion 110 through a screw connection . In addition, a stopper for supporting the rear end of the hair stylus 300 may be formed inside the front end side of the body 110. For example, the eating mosquito according to an embodiment of the present invention is configured as a stopper for supporting the hair stylus 300 by forming a step portion 113 extending inward in the inside of the front end side of the trunk portion 110 . The stepped portion 113 is engaged with the coupling portion 320 of the knife holder 300 between the rear end of the front cover 120 and the knife holder 300 is fixed to the outer housing 100 .

At the rear end of the body 110, a coupling portion for coupling the rear cover 500 may be formed. For example, the mosquito repellant according to an embodiment of the present invention may be configured such that a screw portion 114 is formed on the outer peripheral edge of the rear end side of the body portion 110 and the rear cover 500 is coupled to the body portion 110 through a screw connection .

The front cover 120 may be configured to be inserted into the front of the body 110 by being formed in a shape penetrating the inside of the front cover 120 in the longitudinal direction. To this end, the eating mosquito according to an embodiment of the present invention includes a screw portion 122 having a shape corresponding to the screw portion 112 formed at the front end of the body 110 at the outer periphery of the rear end side of the front cover 120 . A stopper for supporting one end of the first elastic member 600, which will be described later, may be provided at the front end of the front cover 120. For example, the moth according to one embodiment of the present invention is configured to support one end of the first elastic member 600 by forming a stepped portion 124 extending inward at the front end of the front cover 120.

Inside the outer housing 100, a sliding member 200 that moves relative to the outer housing 100 is mounted. The mosquito repellent mosquito according to an embodiment of the present invention includes a front sliding member 210 and a front sliding member 210. The front sliding member 210 and the front sliding member 210 are disposed in front of the sliding member 200 to facilitate disassembly / And a rear sliding member 220 positioned rearward. However, the sliding member 200 may be formed of one integral member like a conventional mosquito.

The front sliding member 210 may be configured to penetrate the inside of the front sliding member in the longitudinal direction, and to insert the tablet 300 through the through hole formed therein. At the rear end of the front sliding member 210, an extending portion 212 extending in the longitudinal direction may be formed. The extension portion 212 contacts a side end portion of the rear sliding member 220 to be described later so that the force generated in the forward direction by the operation of the pressing portion 800 is transmitted to the front sliding member 210 through the rear sliding member 220, And conversely, the force generated in the rearward direction by the first elastic member 600 can be transmitted to the rear sliding member 220 through the front sliding member 210.

According to an embodiment of the present invention, the extension 212 formed on the front sliding member 210 is configured to be partially formed so as to be located only in one direction of the hair removal needle 300 inserted into the front sliding member 210 . When the extension portion 212 of the front sliding member 210 is partially formed so as to be positioned in one direction of the hair removal needle 300, when the hair removal needle 300 is inserted into the front sliding member 210, 212 to minimize interfering with the insertion and removal of the floss 300.

Meanwhile, the mosquito-based mosquito according to one embodiment of the present invention may include a protrusion 214 on the outer circumference of the front sliding member 210. The protrusion 214 formed on the outer periphery of the front sliding member 210 supports one end of the first elastic member 600 to support the first elastic member 600 in the outer housing 100 (Front cover 120 of the sliding door 100) and the sliding member 200 (specifically, the front sliding member 210).

According to an embodiment of the present invention, the front sliding member 210 has a notch 216 having a predetermined length on the front end side. The cutout portion 216 functions to prevent interference from occurring in the process of inserting the hair follicle A into the hair follicle 300. Since the cutter 216 is formed on the front sliding member 210, the hair mosquito according to an embodiment of the present invention is pulled in a state of holding the hair connected to the hair follicle A by using a medical device such as a forceps It is possible to pull the hair follicle A to the end of the front sliding member 210 and further to the inside of the front sliding member 210 (see Fig. 11). Therefore, even if the hair-removal needle 300 is protruded less forward than a conventional mosquito, it is possible to completely insert the hair follicle A so as not to be exposed to the outside of the hair- The cutout portion 216 is preferably formed to have a width equal to or larger than that of the cutout portion 312 formed in the cutout 300 and to be assembled to be positioned in the same direction as the cutout portion 312 of the cutout 300 (See Figs. 5 and 11). Also, according to one embodiment of the present invention, the inner end 218 of the cutout 216 may be formed to be inclined with respect to the knife 300. If the inner end 218 of the cutout 216 is formed to be inclined as described above, interference can be less than when the hair follicle A is inserted as compared with a structure formed vertically.

Since the hair mosquito according to the embodiment of the present invention can be inserted into the sliding member (inner housing) to be inserted into the hair follicle 300 as described above, It is necessary to push forward the hair follicle A located inside the hair follicle 300 to be fully inserted into the skin. This function may be achieved by operation of the mandrel 400 according to an embodiment of the present invention, which will be described in detail later. [Interference by the front end of the sliding member can be avoided when inserting the hair follicle into the hairpin, even if only the cut-out portion is formed in the sliding member in the structure of the conventional eating mosquito, so that the hair follicle is closely attached to the front end portion of the sliding member Thereby making it possible to reduce the front exposure length of the hair removal needles 300 (Y portion shown in Fig. 4). However, if a mosquito is formed so that the hair follicle mounted in the hairpin can be pushed forward through the mandrel as in the embodiment of the present invention, the front exposure length of the hairpin 300 can be further reduced 4) can be removed)

Next, the rear sliding member 220 may have a shape in which the inside thereof penetrates in the longitudinal direction, and the shaft 400 is inserted into the through hole. A screw portion 222 is formed at the rear end of the rear sliding member 220 so that the stopper member 900 operable to cooperate with the pressing portion 800 is engaged. On the other hand, the step portion 224 may be formed on the outer peripheral edge of the rear end side of the rear sliding member 220. The stepped portion 224 is engaged with the rear end surface 510 of the rear cover 500 to restrict the rearward sliding member 220 from being pushed rearward by the elastic force of the first elastic member 600. A recess 226 may be formed on the inner circumferential edge of the rear sliding member 220 on the rear end side thereof so that the engaging portion 420 of the shaft 400 can be inserted.

The hair removal needle 300 is composed of a needle portion 310 whose front end is sharp like a needle so as to be easily inserted into the skin of a patient and a coupling portion 320 formed at the rear of the needle portion 310. The needle portion 310 is formed in a hollow cylindrical shape and a cutout portion 312 having a predetermined length is formed at a front end portion of the needle portion 310 to form a hair follicle A may be exposed through the notch 312 to the outside. The engaging portion 320 of the hair removing needles 300 is formed behind the needle portions 310 and is used to attach the hair removing needles 300 to the outer housing 100. For example, according to one embodiment of the present invention, the engaging portion 320 may be formed in a shape in which a cylindrical shape having a larger diameter than the needle portion 310 of the hair removal needle 300 is partially cut in the longitudinal direction. The reason for forming the engaging portion 320 of the knife holder 300 to be partially cut along the longitudinal direction is that when the knife holder 300 is inserted into the front sliding member 210, So as not to be interfered with by the extension 212 formed in the housing. According to an embodiment of the present invention, the engaging portion 320 of the hair removal needle 300 may include a stepped portion 322 formed at the rear end portion thereof and the stepped portion 322 may be formed at the rear end portion of the front cover 120, (100) by grasping between the stepped portions (113) of the outer housing (110). It is, of course, also possible to form the floss 300 in the outer housing 100 by using the entire engaging portion 320 of the floss 300 without forming the stepped portion 322. The binding portion 320 of the hair removal needles 300 may be formed of the same material as the needle portion 310 (for example, stainless steel) or may be made of a material other than the needle portion 310 (for example, synthetic resin such as acetal or plastic) ).

The mandrel 400 may include a mandrel 410 having an elongated cylindrical shape and an engaging portion 420 formed at a rear end of the mandrel rod 410. The shaft 400 is moved in the longitudinal direction by the operation of the pushing part 800 to push the hair follicle A located inside the hair removal needle 300 forward and remove the hair removal needle 300 from the skin of the patient And functions to prevent the implanted hair follicle A from coming back into the hair follicle 300 when it is removed.

Meanwhile, the rear cover 500 may be mounted on the rear portion of the outer housing 100 according to an embodiment of the present invention. The rear cover 500 is formed in a shape that the front end side is opened and a sliding member 200 (the rear sliding member 220 of the embodiment shown in the drawing) is formed on the rear end surface 510 of the rear cover 500, A through hole is formed. According to an embodiment of the present invention, the rear cover 500 may be configured to be coupled to the trunk portion 110 of the outer housing 100 through the threaded portion 520 formed on the inner periphery. The rear end face 510 of the rear cover 500 is configured to extend inward by a length that can be engaged with the step portion 224 formed on the rear sliding member 220, The rear sliding member 220 is prevented from being pushed rearward through the engagement of the rear sliding member 220 with the rear sliding member 220. The rear cover 500 has a function of adjusting the exposure length of the hair stylus 300 through adjustment of the screw coupling length between the screw 520 of the rear cover 500 and the screw thread 114 of the body 110 . ≪ / RTI >

The first elastic member 600 functions to press the sliding member 200 backward. According to one embodiment of the present invention, the first elastic member 600 may be positioned between the outer housing 100 (or a component fixed thereto) and the sliding member 200. Specifically, the first elastic member 600 is positioned between the stepped portion 124 formed on the front cover 120 and the protruding portion 214 formed on the outer circumferential edge of the front sliding member 210, And may be configured to apply an elastic force in the backward direction.

The second elastic member 700 performs a function of providing an elastic force in the backward direction to the mandrel 400. According to one embodiment of the present invention, the second elastic member 700 may be positioned between the outer housing 100 (or a component fixed thereto) and the mandrel 400. For example, the second elastic member 700 may be mounted between the binding needle 300 fixed to the outer housing 100 and the coupling portion 420 of the mandrel 400, and may be attached to the elastic force of the second elastic member 700 So that the mandrel 400 is elastically pressed in the backward direction.

According to an embodiment of the present invention, a pressing part 800 for operating the shaft 400 and the sliding member 200 is provided at the rear of the sliding member. As described above, in the conventional mosquito nets, the shaft is always moved integrally with the sliding member when the pressing portion is operated. On the contrary, the mosquito type tablet according to one embodiment of the present invention is characterized in that the mandrel 400 is configured to be movable relative to the sliding member 200 as described later.

The stopper member 900 is coupled to the sliding member (the rear sliding member 220 of the embodiment shown in the drawing), and the stopper member 900 is provided with a pressing portion 800 May be connected to each other.

According to an embodiment of the present invention, the pressing portion 800 may include a first cover 810 located at the front and a second cover 820 coupled to the rear of the first cover 810. Although the pusher 800 may be formed of one integral member, it may be more advantageous to disassemble / assemble the mosquito that forms the pusher 800 by combining a plurality of members as in the illustrated embodiment have.

A through hole 812 is formed in the front end surface of the first cover 810 so that the sliding member can pass through the first cover 810 of the pressing portion 800 . The front end surface of the first cover 810 includes an extended portion 814 extending inwardly to engage with a stopper member 900 coupled to the rear of the sliding member, The pushing portion 800 is prevented from being pushed backward by the second elastic member 700 by engaging with the second elastic member 910.

The second cover 820 is formed in a shape in which the front end is opened, and the first cover 810 is configured to be coupled to the front end. The coupling between the first cover 810 and the second cover 820 can be realized through various known coupling means such as screw coupling, snap coupling, and the like.

According to an embodiment of the present invention, the second cover 820 receives the elastic force of the second elastic member 700 through the mandrel 400 (for example, in the case of the illustrated embodiment, the second cover 820 The first cover 822 is configured to contact the rear end of the mandrel 400 to receive the elastic force of the second elastic member 700 and the second cover 820 to be assembled in a state of being elastically pressed backward .

According to an embodiment of the present invention, the second cover 820 of the pressing portion 800 may be configured to be spaced apart from the stopper member 900 in a state where no external force is applied. Since the moth according to the embodiment of the present invention places the second cover 820 of the pressing part 800 and the stopper member 900 in a spaced state as described above, 200). For example, when the user pushes the pressing part 800 of the mosquito repellant according to the embodiment of the present invention forward, the pressing part 800 presses the second elastic member 700 So that the sliding member 200 can move the shaft 400 in the forward direction without moving the sliding member 200 (as shown in FIGS. 12A to 12B). The movement of the shaft 400 acts to move the hair follicle A inserted in the hair follicle 300 forward, and the hair follicle A is completely inserted into the skin.

Thereafter, when the pushing portion 800 is continuously pressed, the shaft 400 is brought into contact with the sliding member 200 (for example, the engaging portion 420 of the shaft 400 is inserted into the rear sliding member 200) An external force is transmitted to the sliding member 200 so that the sliding member 200 moves forward with the shaft 400 in the state shown in Figures 12B to 12C move]. At this time, the hair removal needle 300 is removed from the skin of the patient while moving into the sliding member, as in the operation of a conventional food mosquito (see Fig. 12C).

12B, the timing at which the external force is applied to the sliding member 200 by the pressing portion 800, that is, the time at which the shaft 400 moves alone and is changed to move together with the sliding member 200, As the shaft 400 contacts the sliding member (specifically, the engaging portion 420 of the shaft 400 contacts the end surface of the recess 226 formed in the rear sliding member 220) The external force may also be transmitted to move the sliding member 200 together with the shaft 400. For example, as shown in FIG. 13, the pressing portion 800 contacts the stopper member 900 (b)], the external force may be transmitted to the sliding member through the stopper member 900 so that the sliding member and the shaft may move together. The structure for transmitting the external force to the sliding member through the contact between the pushing portion 800 and the stopper member 900 is a structure in which the depth of the recess 226 formed in the rear of the sliding member, May be realized by forming the stopper member 900 so as not to be in contact with the engaging portion 420 of the stopper member 400 or may be realized by joining the stopper member 900 more shallowly in the structure shown in FIG.

On the other hand, Fig. 14 exemplarily shows another embodiment of the eating mosquito according to the present invention. 14 differs from the mosquito of the previous embodiment in that the second elastic member 700 pushing the mandrel backward is located between the stopper member 900 and the mandrel 400 have.

In the case of the mosquito repellent shown in Fig. 14, as in the case of the mosquito of the previous embodiment, the mandrel 400 has a different elastic member (second elastic member 700) than the first elastic member 600 supporting the sliding member 200, The shaft 400 can be moved forward relative to the sliding member 200 so that the hair follicle A can be moved forward through the shaft 400 do.

However, in the case of the previous embodiment, the first elastic member 600 and the second elastic member 700 may be independently supported on the outer housing 100 side. However, in the embodiment shown in FIG. 14, Since the second elastic member 700 is configured to be supported by the stopper member 900 coupled to the sliding member 200, it is possible to smoothly move the shaft 400 without affecting the sliding member 200 The elastic modulus of the second elastic member 700 is formed to be very small as compared with the elastic modulus of the first elastic member 600 so that the elastic force of the second elastic member 700 before the first elastic member 600 starts elastic deformation It is preferable to first be configured to be stably elastically deformed. When the second elastic member 700 is positioned as shown in FIG. 14, it is preferable to form the guide portion 920 so that the second elastic member 700 can be stably positioned behind the stopper member 900 desirable. Such a guide portion 920 may be used as a structure for setting a relative movement distance of the mandrel 400 with respect to the sliding member 200 as shown in Figs. 14 (b) and 14 (c).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
