Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a hair follicle extractor. Background Technology

[0002] Hair follicle transplantation primarily utilizes microsurgical techniques to extract healthy hair follicles from the back of the head. After special separation of the follicle tissue, it is transplanted to the balding areas to promote hair regrowth. Currently, when using a hair follicle extraction device, the operator mainly relies on pushing a tubular drill into the skin. The direction and depth of the drill insertion are manually controlled by the operator. Operational deviations can affect the efficiency of hair follicle extraction and may even result in the severing of hair follicles, making hair follicle extraction a highly skill-intensive procedure. Utility Model Content

[0003] The purpose of this invention is to provide a hair follicle extractor that allows for adjustment of the drilling depth of the tubular drill into the skin, improving ease of use and flexibility, while ensuring the extraction effect of hair follicles.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] A hair follicle extractor, comprising:

[0006] The handle is a tubular structure open at both ends;

[0007] A push rod has a tubular drill rotatably mounted on its front end and a drive motor for driving the tubular drill to rotate relative to the push rod.

[0008] The push rod is inserted and slidably connected to the handle and cannot be rotated. The front end of the handle is provided with two abutments for pressing against the skin. The two abutments are arranged to the left and right relative to the tubular drill. The end face of the abutment is located between the two ends of the moving trajectory of the front end of the tubular drill. The handle is provided with a limiting bolt to prevent the push rod from disengaging from it. Several corresponding mounting holes for the limiting bolt to pass through are opened at two opposite positions at the rear end of the handle. A strip hole for the limiting bolt to pass through is opened at two opposite positions at the rear end of the push rod.

[0009] As a further improvement to the above technical solution, the central axis of the tubular drill and the two abutments are on the same plane, and the two abutments are arranged symmetrically to the left and right of the tubular drill.

[0010] As a further improvement to the above technical solution, the handle includes a main body and a shock absorber pin. The main body is sleeved on the push rod. The abutment is integrally connected to the front end of the main body and the two abutments are arranged symmetrically on the left and right sides relative to the main body. A through hole for the shock absorber pin to pass through is opened at the opposite position between the two abutments. A first slot hole for the tubular drill to pass through is opened on one end of the shock absorber pin. When the shock absorber pin passes through the two abutments, the handle is connected to the other end of the shock absorber pin by screws.

[0011] As a further improvement to the above technical solution, a limiting post is inserted into one end of the shock-absorbing pin, and the shock-absorbing pin is connected to the limiting post by screws.

[0012] As a further improvement to the above technical solution, the shock-absorbing pin is a tubular structure with openings at both ends, and a second slot is provided on the limiting post for the tubular drill to pass through.

[0013] As a further improvement to the above technical solution, the push rod is provided with a mounting cavity for accommodating the drive motor, and an opening is provided on the end face of the front end of the push rod for the output shaft of the drive motor to pass through, and a tubular drill is fixed on the output shaft.

[0014] As a further improvement to the above technical solution, the bottom ends of the two abutting members are connected by a connecting plate, and the two ends of the connecting plate are integrally connected to the two abutting members respectively.

[0015] As a further improvement to the above technical solution, a collar is integrally connected to the rear end of the push rod.

[0016] As a further improvement to the above technical solution, an extension plate is integrally connected to the rear end of the push rod, and an opening is provided on the extension plate through the push rod along its axial direction.

[0017] As a further improvement to the above technical solution, a spring is provided between the front end of the push rod and the handle to apply a force to the push rod to move away from the handle, with the two ends of the spring abutting against the push rod and the handle respectively.

[0018] Compared with the prior art, this utility model has the following advantages and effects:

[0019] (1) This utility model, through the matching setting of the mounting hole and the strip hole between the handle and the push rod, combined with the connection effect of the limiting bolt on the handle and the push rod, allows the user to adjust the position of the upper limit bolt on the handle to change the distance between the front end of the strip hole and the front end of the abutment, thereby achieving the purpose of adjusting the depth of the tubular drill into the skin, improving the flexibility of the extractor and ensuring the extraction effect of the extractor on the hair follicle.

[0020] (2) This utility model, through the structural arrangement of two abutting members on the handle, reduces the risk of displacement of the extractor by having the abutting members press against the skin. Furthermore, the abutting members act as fulcrums to allow the extractor to swing left and right, ensuring that the angle of the drill bit's entry into the skin aligns with the growth direction of the hair follicle, thereby guaranteeing the efficiency and quality of the hair follicle extraction operation. Additionally, due to the relative positional relationship between the two abutting members and the drill bit, the two abutting members can play a certain positioning role on the skin, improving the accuracy of the drill bit's entry position and ensuring the extractor's effectiveness in extracting hair follicles.

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0030] Example 1.

[0031] See Figures 1-6 This embodiment discloses a hair follicle extractor, including a handle 1 and a push rod 2. The handle 1 is a tubular structure with openings at both ends. A tubular drill 3 is rotatably mounted on the front end of the push rod 2, and a drive motor 4 is installed to drive the tubular drill 3 to rotate relative to the push rod 2. The push rod 2 is inserted into and slidably connected to the handle 1 and cannot rotate. Two abutments 5 are provided on the front end of the handle 1 for pressing against the skin. The two abutments 5 are arranged left and right relative to the tubular drill 3, and the end faces of the abutments 5 are located between the two ends of the moving trajectory of the front end of the tubular drill 3. The handle 1 is provided with limiting bolts 6 to prevent the push rod 2 from disengaging from it. Several mounting holes 7 are provided at two opposite positions at the rear end of the handle 1 for the limiting bolts 6 to pass through. Strip holes 8 are provided at two opposite positions at the rear end of the push rod 2 for the limiting bolts 6 to pass through.

[0032] During hair follicle extraction, hold the handle 1 and, depending on the location of the hair follicle to be extracted on the skin, place the front ends of the two abutments 5 on the handle 1 against the corresponding area of ​​skin. Then, push the push rod 2, causing it to move the tubular drill 3 closer to the skin. Next, using the front ends of the two abutments 5 as fulcrums, swing the extractor so that the drilling angle of the tubular drill 3 is adapted to the growth direction of the hair follicle. Then, drive the motor 4 to drive the tubular drill 3 to rotate, while continuing to push the push rod 2, so that the tubular drill 3 cuts a circular incision on the skin surface. Under the action of the push rod 2, it continues to drill into the skin to a certain depth, thereby severing the structure to which the hair follicle is attached to the skin. Then, remove the extractor from the skin and use medical tweezers to remove the hair follicle from the extractor, completing the extraction.

[0033] In the use of the above-mentioned extractor, the user can change the distance between the front end of the strip hole 8 and the front end of the abutment 5 by adjusting the position of the upper limit bolt 6 of the handle 1, thereby adjusting the depth of the tubular drill 3 into the skin and improving the flexibility of the extractor.

[0034] To reduce the risk of the push rod 2 sliding relative to the handle 1 under gravity during the use of the extractor, thus affecting the extraction operation, a spring 9 can be installed between the front end of the push rod 2 and the handle 1 to apply a force to the push rod 2 to move it away from the handle 1. The two ends of the spring 9 abut against the push rod 2 and the handle 1 respectively (e.g., Figure 6As shown in the diagram, this design ensures that the tubular drill 3 remains retracted between the two retaining members 5 under the push of the spring 9, even without external force pushing the push rod 2. This reduces the possibility of the tubular drill 3 contacting the skin before or simultaneously with the retaining members 5. Furthermore, when the hair follicle extraction is completed and the push of the push rod 2 is released, the push rod 2 automatically resets under the action of the spring 9. This improves ease of use and reduces the risk of the tubular drill 3 becoming exposed between the two retaining members 5 and potentially damaged.

[0035] See Figure 1 The handle 1 has several heat dissipation holes 11 arranged in a dot matrix on its side, which helps to dissipate heat from the drive motor 4 on the push rod 2 inside the handle 1.

[0036] See Figure 1 , Figure 2 The central axis of the tubular drill 3 is on the same plane as the two abutments 5. The two abutments 5 are arranged symmetrically with respect to the tubular drill 3, so that the user can initially locate the drilling position of the tubular drill 3 on the skin by the position of the two abutments 5 against the skin, ensuring the accuracy and convenience of the hair follicle extraction operation.

[0037] See Figures 2-4 The handle component 1 includes a main body 12 and a shock-absorbing pin 13. The main body 12 is sleeved on the push rod 2. Two abutment members 5 are integrally connected to the front end of the main body 12 and are symmetrically arranged relative to the main body 12. A through hole 14 is provided at the opposite position between the two abutment members 5 for the shock-absorbing pin 13 to pass through. A first slot 15 is provided at one end of the shock-absorbing pin 13 for the tubular drill 3 to pass through. When the shock-absorbing pin 13 passes through the two abutment members 5, the handle component 1 is connected to the other end of the shock-absorbing pin 13 by a screw 16. The assembled structure of the handle component 1 allows for a certain gap between the main body 12 and the shock-absorbing pin 13, reducing the intensity of vibration directly transmitted to the handle component 1 during use. This ensures the stability of the user's grip on the lifter, improves the quality of hair follicle extraction, and also allows for the separate manufacturing of each component, reducing the manufacturing difficulty of the handle component 1 and minimizing processing losses.

[0038] To reduce the movement space of the tubular drill 3 within the first slot 15, a limiting post 17 is inserted into one end of the shock-absorbing pin 13. The shock-absorbing pin 13 can be connected to the limiting post 17 by a screw 16. Figure 3 As shown in the image.

[0039] In addition to the above structural configuration, the shock-absorbing pin 13 can be a tubular structure with openings at both ends, and the limiting post 17 has a second slot 18 for the tubular drill to pass through (e.g., Figure 4 As shown in the figure, while ensuring the restriction of the movement space of the tubular drill 3, the stability of the connection between the shock absorber pin 13 and the limit post 17 is also improved.

[0040] See Figure 2 The end face of the abutment 5 is provided with friction texture 51, which can increase the friction between the abutment 5 and the skin when the abutment 5 is against the skin, reducing the risk of the abutment 5 shifting and affecting the hair follicle extraction of the tubular drill 3. The bottom ends of the two abutments 5 are connected by a connecting plate 52. The two ends of the connecting plate 52 are integrally connected to the two abutments 5, which improves the structural strength between the two abutments 5 and ensures the stability of the space between the two abutments 5, thereby ensuring the sliding of the tubular drill 3 between the two abutments 5.

[0041] See Figure 4 , Figure 5 The push rod 2 has a mounting cavity 21 for accommodating the drive motor 4. The end face of the front end of the push rod 2 has an opening 22 for the output shaft of the drive motor 4 to pass through. The tubular drill 3 is fixed on the output shaft, so that the drive motor 4 can be embedded in the push rod 2, reducing the impact of the installation of the drive motor 4 on the appearance of the push rod 2 and facilitating the control of the overall volume of the extractor.

[0042] See Figure 5 The push rod 2 is integrally connected to a collar 23 at its rear end, which allows the user to drive the push rod 2 to slide relative to the handle 1 by hooking the collar 23 with their fingers, thus improving the ease of use.

[0043] Example 2.

[0044] See Figure 7 The structure of this embodiment is basically the same as that of the hair follicle extractor in Embodiment 1, except that: an extension plate 91 is integrally connected to the rear end of the push rod 2, and an opening 92 is provided on the extension plate 91 along the axial direction of the push rod 2. With a spring 9 between the handle 1 and the push rod 2, the influence of the finger on the push rod 2's reset under the action of the spring 9 after the extractor extracts the hair follicle is reduced. At the same time, the opening 92 allows the wires connected to the drive motor 4 to pass through, reducing the influence of the wires on the relative movement between the handle 1 and the push rod 2, ensuring smooth operation of the extractor.

[0045] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
