Examples

The acne needle is a main tool for treating cystic acne, the traditional acne needle is often exposed in the air in treatment and use, if sterilization conditions cannot be met, cross infection can be caused, most of the acne needle is made of metal materials, and the acne needle is easy to rust after long-term use. In the operation process, the needle head is in a continuous exposure state, and the medical staff can be injured by the needle when the needle head is not used properly. Meanwhile, the traditional acne needle adopts a conical needle point, which is not beneficial to controlling the operation strength of each link, increases the skin injury area, influences the wound recovery after treatment and is easy to form various scars. This embodiment aim at provides a medical flexible acne needle that makes things convenient for easy-to-use, its removal that can pass through the slider controls the flexible of syringe needle, can adjust the exposure condition of syringe needle in a flexible way when using, makes things convenient for operating personnel to use and preserve, reduces and is stabbed the risk that takes place cross contamination. The embodiment is realized as follows:

referring to fig. 1 to 5, the present embodiment provides a medical retractable acne needle, which comprises a tube body, wherein the tube body comprises a first end 1 and a second end 2 connected to each other; the first end 1 is provided with a first opening 11, which is hollow and has an inner cavity. The tube body can be cylindrical or cubic, and the embodiment is not limited. The second section can be solid to increase holding stability, can also be hollow to save materials, and can be designed according to actual use requirements. The outer surface of one side of the first end 1 is provided with a sliding chute 3 communicated with the inner cavity, and the sliding chute 3 is provided with a sliding block 31 matched with the sliding chute 3. One end of the slider 31 extends into the cavity and the puncture needle 4 is fixed to this end. The fixed connection of the puncture needle 4 to the slider 31 allows the slider 31 to move the puncture needle 4 relative to each other when moving along the sliding groove 3, so that the first opening 11 is used to allow the puncture needle 4 to protrude out of the first end 1 by the movement of the slider 31. When the puncture needle is used, the sliding block 31 is slid by fingers to realize the extending and stretching of the puncture needle head 4, so that the operation of an operator is more convenient. And a pressing ring 8 is arranged at the outer edge of the end part of the second end 2 far away from the first end 1.

In order to achieve the above-mentioned effect, the geometric center of the first opening 11 is located on the same line as the geometric center of the puncture needle 4. Thus, the puncture needle head 4 can be extended into and deep in the body without any obstacle, and the using effect is achieved. Meanwhile, a stop block 6 is arranged at one end of the sliding chute 3 close to the first opening 11, and the stop block 6 and the sliding block 31 are positioned on the same horizontal plane. Avoiding the slider 31 from disengaging from the chute 3. When the anti-skidding ring is used, the anti-skidding ring 7 is further sleeved on the outer surface of the second end 2, the anti-skidding ring 7 can be made of rubber, patterned plastic and other ferrule parts with friction, and the friction can be increased at the jaw of an operator to facilitate holding and using. Meanwhile, in the embodiment, the top of the sliding block 31 is also provided with anti-skid patterns, so that the puncture needle head 4 can be conveniently pushed out and recovered. And for better service life, the puncture needle 4 and the pressing ring 8 are made of stainless steel materials in the embodiment.

In this embodiment, referring to fig. 3 again, the puncture needle 4 is connected to the slider 31 through the fixed end 32, one end of the puncture needle 4 is connected to the fixed end 32 and is perpendicular to the fixed end 32, and the other end of the fixed end 32 is fixed to the slider 31. The length of the fixing end 32 can flexibly configure the matching mode of the first opening 11 and the puncture needle head 4 during design and production, and the length of the fixing end 32 can be adjusted to ensure that the puncture needle head 4 always just passes through the first opening 11 and can also be adapted to needle heads with more diameters. If the puncture needle 4 is fastened directly to the slider 31, the oblique insertion and extension may be slightly less stable during use. After the needle head is extended out, because the stress of the needle head is opposite to the extending direction of the needle head when in use, in order to avoid the needle head from being pushed back into the tube body, the needle head further comprises a limiting stopper 5 in the embodiment, and the moving direction of the limiting stopper 5 is perpendicular to the moving direction of the sliding block 31 and used for limiting the sliding block 31.

Specifically, referring to fig. 4 and 5 again, the stopper 5 includes a grip 52 and a button 51 fixedly connected to each other; a button 51 is provided on the outer surface of the first end 1 and a grip 52 is shaped to match the shape of the fixed end 32. The button 51 in this embodiment is a commercially available elastic button 51. The fixed end 32 is arranged in a cylindrical manner, the hand grip 52 is designed into a semicircular form, the hand grip 52 can be driven to stretch and retract through the button 51, the limiting of the fixed end 32 is completed after the hand grip 52 is gripped with the fixed end 32, the puncture needle head 4 is used for operating a patient at the moment, and the situation that the needle head retracts cannot occur. And, for more convenient operating personnel uses, stopper 5 can be provided with a plurality ofly along the extending direction of spout 3, can carry out spacingly to puncture needle 4 in different positions, can be suitable for more operation angle.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
