[0032] The operating device described in this embodiment includes a shell 1 and a needle-mounting part 2. The needle-mounting part 2 is in the mounting cavity 111 of the shell 1. The hair-implanting needle 3 is fixed to the connector 21 of the needle-mounting part 2. The operating device is mounted on the hair-implanting needle 3, thereby increasing the holding area of ​​the hair-implanting needle 3. During the hair-implanting operation, the doctor can hold the hair-implanting needle 3 through the operating device, which can improve the grip of the hair-implanting needle 3, make the doctor's grip on the hair-implanting needle 3 more stable, facilitate the doctor's operation on the hair-implanting needle 3, make the insertion of the hair-implanting needle 3 more accurate and rapid, and help improve the efficiency of the operation. In addition, the needle-loading part 2 has an operating position and an installation position. When the needle-loading part 2 is in the operating position, the doctor can operate the hair transplant needle 3 by holding the shell 1. Since the hair transplant needle 3 cannot be used multiple times, it is necessary to frequently replace the hair transplant needle 3. During the replacement process, the needle-loading part 2 is switched to the installation position to expose the connecting head 21 to the installation cavity 111, thereby facilitating the connection and disassembly of the hair transplant needle 3 and the needle-loading part 2. The hair transplant needle 3 can be replaced by switching the position of the needle-loading part 2, so as to facilitate frequent replacement of the hair transplant needle 3, which is beneficial to improving the efficiency of the operation.

[0033] like Figures 2 to 4 As shown, in this embodiment, the outer peripheral side of the housing 1 is provided with a slide groove 114, and the needle-loading part 2 is provided with a slider 24 slidably connected to the slide groove 114. The slide groove 114 is distributed along the axial direction of the housing 1. When the slider 24 moves to the front end of the housing 1 along the slide groove 114, the needle-loading part 2 is in the operating position. When the slider 24 moves to the rear end of the housing 1 along the slide groove 114, the needle-loading part 2 and the housing 1 can rotate relative to each other, and the needle-loading part 2 is rotated to expose the connector 21 to the installation cavity 111, so that the needle-loading part 2 reaches the installation position. Of course, it can be understood that in other embodiments, the slide groove 114 can also be set on the needle-loading part 2, and the corresponding slider 24 can also be set on the inner wall of the housing 1.

[0034] In this embodiment, two slide grooves 114 are symmetrically arranged on the outer peripheral side of the shell 1, and the slide groove 114 passes through the shell 1 and is connected to the installation cavity 111. The slider 24 passes through the slide groove 114 and is connected to the needle loading part 2. The needle loading part 2 is provided with a threaded hole threadedly connected to the slider 24. The two slide grooves 114 can make the sliding of the needle loading part 2 smoother and reduce the possibility of the needle loading part 2 getting stuck, which is beneficial to improving the installation and removal efficiency of the hair transplant needle 3; in addition, the slider 24 is threadedly connected to the needle loading part 2, and by adjusting the distance between the slider 24 and the needle loading part 2, the sliding resistance of the needle loading part 2 can be changed, thereby meeting the use needs of different doctors and improving the doctor's use experience.

[0035] like Figure 7 As shown, the shell 1 in this embodiment includes a gripping portion 11 and a positioning portion 12, the gripping portion 11 is located at the rear end of the positioning portion 12, the installation cavity 111 penetrates the shell 1 along the axial direction of the shell 1, the installation cavity 111 penetrates the rear end of the shell 1 and forms a positioning groove 113 with the shell 1, and the outer peripheral side of the shell 1 is provided with a notch 112 connected with the installation cavity 111, and the needle-loading portion 2 can rotate relative to the shell 1 when it is in the installation position, and the connecting head 21 enters or is exposed in the installation cavity 111 through the notch 112 as the needle-loading portion 2 rotates, and the needle-loading portion 2 rotates at the installation position to expose the connecting head 21 in the installation cavity 111, providing sufficient installation space for the hair transplant needle 3, making the installation and removal of the hair transplant needle 3 simpler and faster, and can speed up the installation and removal of the hair transplant needle 3, which is beneficial to improving the operation efficiency.

[0036] The positioning portion 12 described in the present embodiment is tapered as a whole, and the diameter of the positioning portion 12 gradually decreases as it moves away from the holding portion 11. A through hole 121 is provided in the positioning portion 12 and penetrates the positioning portion 12 axially along the shell 1. The hair transplant needle 3 described in the present embodiment includes a needle tail 31 and a needle head 32. The end of the needle tail 31 is provided with a mounting hole for the connector 21 to be inserted, and the diameter of the needle tail 31 is larger than the needle head 32. When the needle mounting portion 2 is in the operating position, the connector 21 drives the hair transplant needle 3 to be inserted into the through hole 121. The diameter of the end of the through hole 121 is larger than the front end of the through hole 121, so that the connector 21 and the needle tail 31 can be inserted. At this time, the connector 21 cooperates with the through hole 121 to limit the rotation of the needle mounting portion 2, so that the needle mounting portion 2 remains stable during the needle-piercing process, which is beneficial to improving the accuracy of the needle-piercing and reducing the possibility of the hair transplant needle 3 being inserted into the wrong position.

[0037] In this embodiment, the outer peripheral side of the positioning portion 12 is provided with an avoidance notch 122 connected to the through hole 121. The width of the avoidance notch 122 is greater than the needle head 32 of the hair transplant needle 3 and smaller than the diameter of the connecting head 21. In the process of replacing the hair transplant needle 3, the needle mounting portion 2 can rotate when the connecting head 21 is separated from the through hole 121. The hair transplant needle 3 rotates with the needle mounting portion 2 and directly enters or leaves the through hole 121 through the avoidance notch 122. The avoidance notch 122 can shorten the moving distance of the needle mounting portion 2, thereby accelerating the installation and removal speed of the hair transplant needle 3. At the same time, the length of the gripping portion 11 can also be reduced, making the operating device more compact as a whole, which is conducive to carrying and storing the operating device and can also reduce the manufacturing cost of the operating device.

[0038] In addition, in order to make the doctor hold the grip portion 11 more stably, an anti-skid layer is provided on the outer peripheral side of the housing 1 in this embodiment, which can increase the friction between the housing 1 and the fingers, making the doctor hold the operating device more stably and facilitating the doctor to operate the operating device. Of course, it can be understood that in other embodiments, the anti-skid layer can be provided with anti-skid grooves 114 at intervals on the surface of the housing 1, or an anti-skid pad can be attached to the surface of the housing 1.

[0039] like Figure 2 and Figure 5 As shown, the needle-loading part 2 in this embodiment includes a baffle 22 and a pressing plate 23, and the two ends of the baffle 22 are respectively connected to the pressing plate 23 and the connector 21. When the needle-loading part 2 is in the operating position, the baffle 22 blocks the notch 112, and the pressing plate 23 is embedded in the positioning groove 113. When the needle-loading part 2 is in the operating position, the baffle 22 blocks the notch 112, which can increase the doctor's gripping area, so that the doctor can grip and operate it more conveniently, thereby improving the doctor's user experience. In addition, during the operation, the doctor presses one finger on the pressing plate 23 to press the pressing plate 23. The plate 23 is maintained in the positioning groove 113, and the positioning groove 113 can limit the pressing plate 23, thereby limiting the rotation of the needle-loading part 2, which is beneficial to improving the stability of the needle-loading part 2, and can avoid the deflection of the hair transplantation needle 3 during the needle-piercing process, and can improve the accuracy of the needle-piercing; secondly, the doctor can also limit the axial movement of the needle-loading part 2 by pressing the pressing plate 23, and at the same time, external force can be applied to the hair transplantation needle 3, so that the hair transplantation needle 3 can be stably inserted into the position where the hair follicle needs to be implanted, and the hair transplantation needle 3 can be inserted to a sufficient depth, which is beneficial to improving the surgical effect.

[0040] In addition, in this embodiment, a groove 231 is provided on the pressing plate 23. When the needle loading part 2 is in the operating position, the doctor presses one of his fingers on the pressing plate 23, thereby limiting the relative sliding of the needle loading part 2 and the shell 1, so that the needle loading part 2 can be stably maintained in the operating position. The groove 231 can accommodate the fingertip of the finger, thereby increasing the friction between the finger and the pressing plate 23, reducing the possibility of slipping between the finger and the pressing plate 23, and allowing the doctor to apply stable pressure to the pressing plate 23.
