[0002] In hair transplantation surgery, the extraction and transplantation of hair follicles are key steps. The traditional method of hair follicle extraction is often to insert an extraction needle into the skin, separate the hair follicle from the surrounding tissue, and then use a negative pressure device connected to the hollow end of the extraction needle to suck it out through negative pressure, or use forceps to clamp it out. In either case, other equipment is required for cooperation, and using forceps also highly tests the doctor's skills. Otherwise, excessive force may cause squeezing damage to the hair follicles.

[0003] In order to better extract hair follicles, be able to directly take them out after separation without the need for other equipment, and be able to assist in the force of clamping the hair follicles to avoid squeezing damage, and at the same time be able to accurately control the material usage and have a fast production speed through existing 3D printing technology, which is of great significance for clinical and market demands. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that it is necessary to use other equipment for cooperation whether it is taken out by negative pressure adsorption or clamped by forceps, and using forceps also highly tests the doctor's skills. Otherwise, excessive force may cause squeezing damage to the hair follicles, and a personalized hair transplantation device based on 3D printing technology is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A personalized hair transplantation device based on 3D printing technology includes an extraction needle. The extraction needle is divided into a handheld part and a drilling part arranged at the end of the handheld part, and the diameter of the handheld part is larger than that of the drilling part. The centers of both the handheld part and the drilling part are hollow.

[0007] A clamping component for clamping the hair follicle. The clamping component is arranged inside the handheld part. The clamping component includes a fixed clamping strip and a movable clamping strip. The fixed clamping strip is fixedly arranged on one inner wall of the handheld part. There is a gap between the fixed clamping strip and the movable clamping strip, and the bottoms of both the movable clamping strip and the fixed clamping strip extend into the drilling part.

[0008] An adjusting component for clamping and limiting the movable clamping strip. The adjusting component is arranged on one side of the handheld part.

[0009] In a possible design, two inclined plates are fixedly arranged on the inner wall of one side of the handheld part close to the movable clamping strip. Two inclined grooves are formed in the outer wall of the movable clamping strip, and the two inclined grooves are respectively matched with the two inclined plates.

[0010] In a possible design, a side hole is formed in the outer wall of the handheld part close to the movable clamping strip, and the side hole is communicated with the inside of the handheld part. One side of the movable clamping strip is fixedly provided with a connecting plate, and one end of the connecting plate extends to the outside through the side hole.

[0011] In a possible design, the adjusting assembly includes a limiting rod. A plurality of limiting grooves communicated with the outside are formed in the inner walls of both sides of the side hole, and the limiting grooves are located above the connecting plate. The two ends of the limiting rod are respectively matched with the corresponding limiting grooves on both sides.

[0012] In a possible design, a sliding groove is formed in one side of the outer wall of the handheld part, and the bottom end of the sliding groove is communicated with the top end of the side hole. Side grooves are formed in the inner walls of both sides of the sliding groove. The same cross bar is arranged between the two side grooves. One side of the outer wall of the cross bar located inside the sliding groove is fixedly provided with a connecting rod, and the bottom end of the connecting rod is fixedly arranged on the outer wall of the limiting rod.

[0013] In a possible design, a dial is fixedly arranged on the outer wall of the limiting rod, and the dial extends to the outside through the side hole. A push plate is fixedly arranged on one side of the connecting plate.

[0014] In a possible design, inclined surfaces close to each other are formed at the bottom ends of the fixed clamping strip and the movable clamping strip.

[0015] In the present application, during specific use, one end of the drilling part is inserted into the scalp. Then, while pressing the push plate, it is pushed upward. At this time, the movable clamping strip will move upward and approach the fixed clamping strip through the cooperation of the inclined plate and the inclined groove, so as to clamp the hair follicle. Then, the extraction needle can be taken out, and it can be moved outwards through the dial, so that the limiting rod rotates with the cross bar, and the limiting rod is moved out of the inner part of the limiting groove. Then, the cross bar can be moved up and down to adjust to a suitable height, and then the limiting rod is rotated back into the corresponding limiting groove. When the push plate is pushed to drive the movable clamping strip to clamp, it will not be able to move when touching the limiting rod, so as to control the clamping gap between the movable clamping strip and the fixed clamping strip within a certain range, preventing excessive force from causing extrusion damage to the hair follicle.

[0016] In the present utility model, for the personalized hair transplantation device based on 3D printing technology, through the clamping assembly, after the drilling part is inserted into the skin, by pressing and sliding the push plate, the movable clamping strip can be driven to move, so as to directly clamp the hair follicle, and the effect of taking it out without using a negative pressure device or subsequent devices such as tweezers can be achieved;

[0017] In the present utility model, for the personalized hair transplantation device based on 3D printing technology, through the adjusting component, the clamping distance between the movable clamping strip and the fixed clamping strip can be limited and adjusted. Before use, the limiting rod can be engaged in a suitable limiting groove according to the actual situation. Then, when the push plate is pushed for clamping, it can be controlled within a certain range to prevent the phenomenon that excessive force will cause extrusion damage to the hair follicles.

[0018] In the present utility model, during use, first, the clamping range of the movable clamping strip is controlled within the moving range through the adjusting component to prevent the problem of excessive force and extrusion damage during subsequent clamping and extraction.

[0019] Then, one end of the drilling part is inserted into the skin to separate the hair follicle from the surrounding area. Subsequently, the push plate is pressed to clamp the hair follicle through the clamping component and take it out, without the need to cooperate with other devices later for extraction.

[0031] Embodiment 2

[0032] Reference Figure 4 , on the basis of Embodiment 1, an improvement is made: a personalized hair transplantation device based on 3D printing technology, which is applied to the field of 3D printing. The design of the adjusting component is as follows: On both inner walls of the side hole 8, a plurality of limiting grooves 15 communicating with the outside are respectively opened. These limiting grooves 15 are located above the connecting plate 7. Both ends of the limiting rod 16 cooperate with the corresponding limiting grooves 15 on both sides respectively. By moving the limiting rod 16, the clamping limit of the movable clamping strip 5 can be realized. In order to facilitate the operation of the limiting rod 16, a sliding groove 13 is also opened on one side of the outer wall of the handheld part 3. The bottom end of the sliding groove 13 is communicated with the top end of the side hole 8. Side grooves 12 are provided on both inner walls of the sliding groove 13, and a cross bar 14 is installed between the two side grooves 12. A connecting rod 9 is fixed on the cross bar 14, and the bottom end of the connecting rod 9 is fixedly connected to the outer wall of the limiting rod 16. In addition, a dial 17 is fixed on the outer wall of the limiting rod 16, and the dial 17 extends to the outside through the side hole 8, facilitating the user to directly dial to adjust the position of the limiting rod 16.

[0033] Specifically, by moving the paddle 17 outwards, the limit rod 16 rotates around the cross bar 14, and the limit rod 16 is moved out of the inside of the limit groove 15. Then, the cross bar 14 can be moved up and down to adjust to a suitable height, and then the limit rod 16 is rotated back into the corresponding limit groove 15.
