Description

Technical Field

[0001] The utility model relates to the technical field of hair planting, in particular to a handheld device for hair follicle extraction and drilling. Background Art

[0002] At present, FUE (follicular unit extraction) is widely used in the field of hair transplantation. Compared with traditional hair transplantation surgery, it is more delicate and minimally invasive and is a commonly used hair transplantation technology. Doctors use micro instruments to perform surgery, such as micro rotating drills, to extract and drill holes one by one for transplantation.

[0003] Existing miniature electric hand drills for doctors have the following defects:

[0004] When doctors use micro-hand drills to drill hair follicles, the cutting speed is fast, the cutting heat is high and it is difficult to dissipate heat, which increases the temperature of the contact point between the workpiece and the drill bit, aggravates the wear of the drill bit, and is not conducive to the activity of the hair follicles; due to the limitations and difficulty of operation of the micro-drill, the probability of hair follicle extraction may be reduced, thereby affecting the surgical effect, and the surrounding hair follicle units may be damaged during extraction and drilling, affecting the quantity and quality of hair follicle planting, and also causing poor postoperative healing effect, ultimately affecting the planting effect; when performing FUE surgery, doctors need to have superb surgical skills and rich clinical experience to ensure that the hair follicle units can be accurately and effectively extracted. Manual cutting may cause potential damage to surrounding tissues and hair follicles, which is not conducive to the patient's later recovery. The problem of poor final effect is caused by the simple tools and the difficulty of operation. For this reason, a solution needs to be given. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2 The embodiment of the utility model provides a technical solution: a handheld device for hair follicle extraction and perforation, comprising a device body 1, wherein the device body 1 comprises a shell device 2, a driving motor 3 and a microneedle device 4, wherein the driving motor 3 and the microneedle device 4 are both installed inside the shell device 2, and the rear end of the microneedle device 4 is fixed to the driving end of the driving motor 3;

[0019] The problem is that the microneedle device 4 includes a microneedle 5, a first rotating bearing 6, a second rotating bearing 7, a limiting fixing block 8 and a fixed sleeve 9. The first rotating bearing 6, the second rotating bearing 7, the limiting fixing block 8 and the fixed sleeve 9 are sequentially sleeved on the microneedle 5. The limiting fixing block 8 and the fixed sleeve 9 are both cylindrical structures and are through-type structures. The front ends of the limiting fixing block 8 and the fixed sleeve 9 are both provided with a small sleeve 13. The small sleeve 13 is a cylindrical structure and is a through-type structure. When in use, the driving end of the driving motor 3 is driven, and then the microneedle in the microneedle device 5 is driven to rotate. In this way, drilling can be performed, and the first rotating bearing 6, the second rotating bearing 7, the limiting fixing block 8 and the fixed sleeve 9 are for facilitating the smoothness and stability of the microneedle rotation, and can also facilitate the stable installation of the microneedle 5.

[0020] Furthermore, the housing device 2 includes a connector 10, a main housing 11 and a rear sealing cover 12. The main housing 11 is installed at the rear end of the connector 10 by means of threads, and the rear sealing cover 12 is installed at the rear end of the main housing 11 by means of threads. The connector 10 is a conical structure, and the connector 10, the main housing 11 and the rear sealing cover 12 are connected by means of threads, thereby facilitating the staff to disassemble and install the device body 1.

[0021] Differently, a control button 14 is disposed on the side of the rear sealing cover 12 , and a staff member can operate the device body 1 by pressing the control button 14 .

[0022] Working principle: During the operation, the doctor holds the handle to extract the hair follicles. The doctor selects the hair extraction function in the upper computer software, activates the handle, and the system outputs instructions. The motor inside the device drives the microneedle to rotate. At the same time, the air circuit automatically starts to inhale under the control of the instruction, and the doctor aims at the hair follicles for extraction. Punching, the doctor holds the handle to punch the hair follicles. The doctor selects the punching function in the upper computer software, activates the handle, and the system outputs instructions. The driving end of the drive motor 3 is driven, and then the microneedle in the microneedle device 5 is driven to rotate. In this way, the punching work can be carried out. At the same time, the air circuit automatically starts to inhale under the control of the instruction, and the doctor punches at the position where the hole needs to be punched.

[0023] The utility model comprises 1, a device body; 2, a housing device; 3, a driving motor; 4, a microneedle device; 5, a microneedle; 6, a first rotating bearing; 7, a second rotating bearing; 8, a limit fixing block; 9, a fixing sleeve; 10, a connector; 11, a main housing; 12, a rear sealing cover; 13, a small sleeve; 14, a control button. All the components are universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. The utility model solves the problem that when existing doctors use micro hand-held electric drills to drill hair follicles, the cutting speed is fast, the cutting heat generated is high, and the heat dissipation is poor. The difficulty of cutting the hair follicles increases the temperature of the contact point between the workpiece and the drill bit, aggravates the wear of the drill bit, and is not conducive to the activity of the hair follicles; due to the limitations and difficulty of the micro drill bit, the probability of hair follicle extraction may be reduced, thereby affecting the surgical effect, and the surrounding hair follicle units may be damaged during extraction and drilling, affecting the quantity and quality of hair follicle planting, and also causing poor postoperative healing effect, which ultimately affects the planting effect; when performing FUE surgery, doctors need to have superb surgical skills and rich clinical experience to ensure that the hair follicle units can be accurately and effectively extracted. Manual cutting may cause potential damage to the surrounding tissues and hair follicles, which is not conducive to the patient's later recovery. Due to the problem of poor final effect caused by the simple tools and high difficulty in operation, the utility model can increase the rotation speed and power through the mutual combination of the above-mentioned components, which can speed up the extraction speed of hair follicle units and improve surgical efficiency, thereby shortening the operation time and reducing the discomfort and fatigue of patients.
