Abstract

The present invention relates to a hair transplant device structure used in hair transplant surgery. Disclosed is a form in which a depth adjustment guide integrated with a needle is applied to reduce a depth of the needle inserted into the patient's skin. The depth adjustment guide protrudes through a nozzle together with the needle, and a nozzle hole includes a nozzle lower end expansion hole for passing the depth adjustment guide. In typical hair transplant surgery, hair follicles are mounted deeper than a bevel part of the hair transplant needle, and a procedure is performed so that the hair follicles are not damaged when the needle passes through the hard skin epidermis. As a result, the needle is inserted deeper into the skin by a length of the bevel part than a length of the hair follicles, which increases a patient's pain and bleeding. The depth adjustment guide reduces the depth at which the needle is inserted and then slides with the hair transplant nozzle to have an effect of moving a hair transplant mandrel axis relatively forward, and pushes the hair follicles into the skin. Accordingly, according to the present invention, a technology designed to support settlement of the hair follicles in the skin at the depth intended by a practitioner while reducing the length of the needle inserted into the patient's skin is disclosed.

Description

Hair transplantation device with nozzle and relatively sliding needle insertion depth adjustment guide in which the guide for depth adjustment slides with the nozzle

The present invention relates to a hair transplanter for hair transplantation surgery, and more particularly, to a hair transplanter having a guide for adjusting the depth when a needle is inserted for hair transplantation and operated by sliding with a nozzle.

An implanter for hair transplantation is a medical device used in hair transplantation surgery that collects hair from a hair growth region of the scalp and transplants it by planting it in the scalp of another barren region where hair loss has occurred.

A conventional hair transplanter inserts a hair follicle into the hollow needle attached to the front, inserts it into the skin, lifts the handle, and the needle coupled with the handle comes out of the skin. It works to stay inside. Related prior art has been disclosed in <Registration No. 10-0417829 Hair Transplantation Machine (Destroyed)> or <Registration No. 10-0958727 Hair Transplantation Machine>.

In addition, there is a multi-type hair transplanter with a plurality of needle channels. <Registration No. 10-2048492 Hair Transplanter consisting of a plurality of needle channels arranged radially>

No. 10-0417829 (hair transplanter) No. 10-0958727 (hair transplanter) No. 10-2048492 (Hair transplanter consisting of multiple needle channels arranged radially) No. 10-1232394 (hair transplanter equipped with a depth adjusting member) No. 10-1806970 (planter)

When performing hair transplantation with a hair transplanter, the hair follicle inserted into the needle is usually inserted inside the bevel section, which is a sharp shape at the tip of the needle. This is because when the needle is inserted into the patient's scalp, if the hair follicle is not completely protected by the needle and is partially exposed, there is a high possibility of damage. However, as a result, the length at which the needle is inserted into the patient's scalp is inserted deeper by the bevel length (about 2 to 4 mm) of the needle compared to the depth at which the hair follicle is inserted. This increases the patient's pain and causes an increase in blood loss. Conventionally, a structure in which a depth adjusting member is integrally formed with a nozzle has been disclosed in order to insert a needle into the patient's scalp less than the length exposed out of the nozzle. <Registration No. 10-1232394 hair transplanter equipped with a depth adjusting member> However, this structure is such that the depth adjusting member and the nozzle are integrated, so that the nozzle touches the scalp after the step of inserting the needle less into the patient's scalp. It cannot be pushed in so that the hair follicles are completely inserted into the scalp.

As another type of prior art, a cutout is formed in the nozzle, and the length of the needle protruding to the tip of the nozzle is formed by forming a cutout in the nozzle and placing the mandrel in the needle deeper than the nozzle, which usually coincides with the tip of the nozzle, so that the hair follicle is mounted deeper than the tip of the nozzle. There has been disclosed a form in which the hair follicle is completely inserted into the scalp by reducing the depth of needle insertion into the patient's scalp and then pressing the rear cover to advance the mandrel. <Registration No. 10-1806970 hair transplanter> However, this structure actually advances the mandrel relative to the nozzle position, and cannot be used for multi-type hair transplanters.

On the other hand, in the shape of the needle bevel, a sharp tip is formed at the bottom by grinding the top of the needle obliquely, and when the needle passes through the small nozzle hole, the bottom of the nozzle and the bevel end of the needle collide, resulting in inoperable failure or damage to the needle. damage occurs.

This failure occurs much more frequently in a multi-type hair transplanter in which a plurality of tacking channels must pass through one nozzle hole while rotating.

The needles of the hair transplanter are usually manufactured in a state of bonding with a resin or metal needle hub.

The operator retreats the needle protruding out of the nozzle into the nozzle by holding the handle with the thumb and middle finger while pressing the rear cap of the hair transplanter with the index finger and lifting it. It is configured so that the movements are interlocked in such a way as to interlock through the.

The present invention forms long bar-shaped protrusions on the needle hub and adheres or joins them to the lower end of the needle to partially protrude out of the nozzle together with the needle. This needle hub protrusion reduces the depth at which the needle is inserted into the patient's scalp. It is designed to serve as a depth control guide.

When the needle is inserted into the scalp, the depth control guide first touches the scalp before the tip of the nozzle touches the scalp and stops the insertion.

After that, the operator presses the back cap of the hair transplanter with his index finger and lifts the handle with his thumb and middle finger. At this time, the depth control guide, which moves with the needle, is temporarily fixed in contact with the scalp, and the nozzle descends to the scalp, and the axis inside the needle is also fixed. The nozzle and movement descend in an interlocking state to completely push the hair follicle into the scalp.

After the nozzle contacts the scalp, the needle linked with the handle rises and completely comes out of the scalp, and the hair transplant operation is completed when the hair transplanter is lifted and removed from the scalp.

On the other hand, the lower end of the nozzle hole is configured to open in a more expanded state so that the depth control guide can pass.

When a hair transplanter needle is inserted into the patient's scalp, a structure capable of improving this problem has long been required due to increased pain and bleeding of the patient as the needle is inserted deeper by the length of the needle's sharp bevel shape.

After the needle pierces the hardest epidermis of the scalp, even if the hair follicle is pushed into the scalp, the possibility of damage to the hair follicle is low. there will be

In addition, the lower end of the nozzle hole is opened in a more expanded state so that it does not directly meet the sharp end of the needle, but meets the depth control guide that can easily slide, so that inoperability or damage to the needle due to collision can be prevented.

The above objects, other objects, features and advantages of the present invention will be easily understood through the following preferred embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, the embodiments introduced herein are provided so that the disclosed content will be thorough and complete, and the spirit of the present invention will be sufficiently conveyed to those skilled in the art.

In this specification, singular forms also include plural forms unless specifically stated otherwise in a phrase. The terms 'comprise' and/or 'comprising' used in the specification do not exclude the presence or addition of one or more other elements.

Hereinafter, the present invention will be described in detail with reference to the drawings. In describing specific embodiments below, various specific contents are prepared to explain the invention in more detail and aid understanding. However, readers who have knowledge in this field to the extent that they can understand the present invention can recognize that it can be used without these various specific details. In some cases, it is mentioned in advance that parts that are commonly known in describing the invention and are not greatly related to the invention are not described to prevent confusion in describing the present invention.

1, 2, 4, 6, 7, and 8 show that the structure of the present invention, the depth control guide, can be implemented in a multi-type hair transplanter and a single hair transplanter.

The depth control guides 11 and 111, which are the core structure of the present invention, are manufactured integrally with the needle hubs 10 and 110 bonded to the needles 30 so that the needles move in conjunction with the handles 50 and 150 of the hair transplanter. It is manufactured separately, but it is configured in the form of a long bar integrated by joining or assembling.

The depth control guides 11 and 111 are configured to protrude to the outside through the extension holes 21 and 121 at the lower ends of the nozzles in a state of close contact with the lower ends of the needles 30 and 130 . At this time, the depth control guides 11 and 111 and the needles 30 and 130 may be bonded separately.

3 and 9, the mandrels 40 and 140 are positioned within 3 mm of the front and rear ends of the nozzles 20 and 120, and the depth control guides 11 and 111 are advanced further than the mandrels in the standby state. consists of

The standby state means that the needle protrudes out of the nozzle by the spring without the external force of the conventional hair transplanter.

Figure 5 shows the role of the depth adjustment guide (11, 111) when implanted on the patient's skin.

When the needles 30 and 130 are inserted into the skin, the conventional hair transplanter has a structure that can be inserted until the tips of the nozzles 20 and 120 come into contact with the patient's skin, but the depth control guides 11 and 111 are configured When it is, the needle insertion depth is reduced by the depth control guide.

Thereafter, the operator's hair transplanting operation is to lift the handles 50 and 150 with the thumb and middle finger while pressing the back caps 60 and 160 with the index finger. At this time, the nozzles 20 and 120 advance until they come into contact with the skin. . Since the mandrels 40 and 140 move in conjunction with the nozzle during the hair transplanting operation due to the structure of the normal hair transplanter, the mandrels 40 and 140 also move forward when the nozzles 20 and 120 advance, so that the hair follicles installed in the needles 30 and 130 ( b and c) are pushed into the skin.

Then, the needles 30 and 130 completely come out of the skin, and when the hair transplanter is lifted, the hair follicles b and c remain in the skin, and the mandrels 40 and 140 and the hair follicles b and c are separated, and hair transplantation is completed.

Referring to FIGS. 10 and 11, the hole through which the needle protrudes from the nozzle is usually formed in a circular shape, but when the present depth control guides 11 and 111 are applied, the nozzle 20 ) at the lower end of the nozzle, expansion holes 21 and 121 are formed.

In a normal hair transplanter, the needle bevel ends (31, 131) of the needles (30, 130) are configured to face the bottom of the nozzle hole. When the needle passes through the narrow nozzle hole, it collides with the bottom of the nozzle, resulting in malfunction or damage to the needle. failure is likely to occur.

The structure of the present invention is configured to reduce the possibility of failure by extending the distance between the needle bevel ends 31 and 131 and the nozzle hole as the nozzle lower expansion holes 21 and 121 are configured.

On the other hand, in the case of a single hair transplanter, when the hair follicle (c) is attached to the needle 130, the hair follicle is attached to one needle protruding out of the nozzle and inserted into the skin, so the hair follicle does not pass through the nozzle hole, In the case of a multi-type hair transplanter, hair follicles are attached to needles other than one needle protruding out of the nozzle without protruding out of the nozzle, and then the needles protrude through the nozzle hole one by one while rotating, so that the attached hair follicle also passes through the nozzle hole. . Therefore, hair protruding out of the needle through the slit of the needle or skin attached to the hair follicle may interfere with the top of the nozzle hole.

Referring to FIG. 3 , this problem can be solved by further configuring a nozzle top cutout 22 at the top of the nozzle.

The depth control guides 11 and 111, which are the core structure of the present invention, operate in conjunction with the needles 30 and 130 integrally, and in addition to the two embodiments shown as a structure accompanying the expansion holes 21 and 121 at the bottom of the nozzle, It is a structure that can be equally applied to hair transplanters for hair transplantation.

In addition, those skilled in the art to which the invention pertains can understand that various modifications and variations are possible from the description of this specification. Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined, but should be defined by not only the claims to be described later, but also those equivalent to these claims.
