Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a labial fixation mechanism for a labial cutting stapler. Background Technology

[0002] With societal progress, the medical industry is booming. Among the emerging medical devices, the labiaplasty stapler is primarily used for labiaplasty. Traditional labiaplasty typically involves cutting with a scalpel or medical scissors, a cumbersome procedure requiring advanced technical skills. In response, labiaplasty staplers have emerged, using tools to fix the labia and then quickly suturing after the cutting. These staplers are time-saving and labor-saving, and have gained widespread market acceptance. The tool used to fix the labia is called a labia fixation mechanism, which can be categorized into inversion fixation and eversion fixation based on the different labiaplasty methods.

[0003] In existing technologies, such as the Chinese invention patent publication number CN111436990B, a "labia cutting and suturing device" is disclosed, which includes a pusher sleeve shell with a pusher sleeve receiving cavity and an elliptical left end; a pusher sleeve that cooperates with the pusher sleeve receiving cavity, with an elliptical left end and pusher claws extending from the front and rear of the left end face, and pusher claw notches formed between the upper and lower parts of the pusher claws at the front and rear of the left end face; a nail carrier plate disposed in the pusher sleeve receiving cavity, with nail carrier holes on the nail carrier plate; a suture nail foot bending plate that cooperates with the nail carrier plate; a pusher sleeve driving mechanism connected to the right end of the pusher sleeve shell; a knife anvil located on the left side of the suture nail foot bending plate; a knife anvil tightening adjustment mechanism connected between the knife anvil and the pusher sleeve driving mechanism; and a pair of blades embedded in the cavity wall of the pusher sleeve cavity, with the blade edge of the left blade protruding from the end of the pusher claw and corresponding to the nail carrier plate cavity. While this technique can perform labial incision and suturing, it employs an inverted labial cutting and suturing structure. As is well known, the earliest foreskin cutting and suturing devices used an inverted structure, and the above technique follows the traditional inverted foreskin cutting and suturing method. The problem with this inverted structure in actual use is that, due to the significant differences between labial cutting and foreskin cutting, the labia are difficult to stabilize and fix after inversion like the foreskin. Moreover, the inverted labia, once fixed inside the cutting and suturing device, are difficult to observe. Therefore, it is difficult for doctors to accurately judge the clamping status and cutting situation of the labia, and the appearance of the labial cutting cannot be guaranteed, thus failing to meet the needs of doctors and clients.

[0004] For example, the "Labia Suturing Cutter" provided by Chinese Invention Patent Publication No. CN111436989B includes a pusher sleeve shell with a pusher sleeve receiving cavity and an elliptical shape at the left end; a pusher sleeve, which cooperates with the pusher sleeve receiving cavity, with an elliptical shape at the left end and pusher claws at the front and rear of the left end face; a nail carrier plate, which is elliptical and located in the pusher sleeve receiving cavity, and has nail carrier holes on it; a suture nail foot bending plate, which cooperates with the nail carrier plate, and has a recess for bending nail feet on its left side; a pusher sleeve driving mechanism, which is connected to the right end of the pusher sleeve shell; a labia guide positioning plate, which is located on the left side of the suture nail foot bending plate; and a labia guide positioning plate tightening adjustment mechanism, which is connected between the labia guide positioning plate and the pusher sleeve driving mechanism. This technical solution overcomes the limitations of inversion by adopting a labial eversion suture structure, exposing the labia to the outside of the suture cutter so that they can be observed. However, in actual operation, because the position of the labia is changed, the blade that was originally located on the inside cannot cut the labia. The doctor can only make a manual cut on the outside of the suture cutter with a scalpel. The suture cutter can only fix the labia and suture, so it still cannot meet the needs of doctors and clients. In addition, although the labial eversion guide plate used to guide the labia can fix the labia eversion, it has been found in actual use that the labia are difficult to introduce, and eversion will flatten the labia, which is not conducive to plastic surgery aesthetics.

[0005] In view of the aforementioned problems, it is necessary to design a labia fixation mechanism for a labia cutting stapler that can evert the labia, reduce the difficulty of labia insertion, and maintain a gradual eversion curvature of the labia. To this end, the applicant has ingeniously designed this technical solution. Utility Model Content

The suture pins are in the aforementioned The curved screw groove 651 and the push screw tooth 34 work together to bend and fix the wound. After the operation is completed, the aforementioned handle 9 is pried open in the opposite direction, so that the push rod 91 pulls the top body 8 to move backward in the drive sleeve hole 11. The aforementioned top body 8 pulls the cutting push screw sleeve 3 to move backward, so that the blade 35 is retracted into the outer protective shell 2, thereby avoiding secondary damage to the blade 35. Finally, the aforementioned labia fixing and tightening adjustment mechanism 7 is rotated in the opposite direction, so that the labia fixing mechanism 6 is disengaged and the clamping state on the labia is released, thereby completing the entire surgical process.
