Description

Technical Field

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

[0002] With societal progress, the medical industry is booming. Among the emerging medical devices, the labiaplasty stapler is primarily used for labial reshaping. Traditional labial reshaping typically involves cutting with a scalpel or medical scissors, a cumbersome procedure requiring highly skilled technicians. To address this, several labiaplasty staplers have emerged on the market. These devices fix the labia with a tool and then quickly suture after cutting. This makes the procedure time-saving and labor-saving, and has gained widespread market acceptance. The cutting and suturing mechanism is the core component of the labiaplasty stapler, mounted on the drive mechanism. It is used for cutting and suturing the labia, and the stapler can be reused by replacing the cutting and suturing mechanism when necessary. Current cutting and suturing mechanisms typically employ a structure where suture staples are placed in a staple cartridge, and a drive mechanism pushes the cutting and suturing mechanism to eject the suture staples. The suture staples are generally in the shape of the character "[". After the two legs pass through the skin and flesh and are bent and sutured, the connection between the two legs often embeds into the skin and flesh due to the difference in skin and flesh thickness, which has an adverse effect on the appearance of the labia after recovery.

[0003] In existing technologies, such as the "Labia Cutting and Suturing Device" disclosed in Chinese Invention Patent Publication No. CN111436990B, a pusher sleeve shell is included, which has a pusher sleeve receiving cavity and is elliptical at its left end; a pusher sleeve, which cooperates with the pusher sleeve receiving cavity, is elliptical at its left end and has pusher claws extending from the front and rear of the left end face, and a pusher claw is formed between the upper and lower parts of the pusher claw at the front of the left end face and the pusher claw at the rear of the left end face. The device includes: a nail claw notch; a nail carrier tray located within the nail pusher sleeve cavity, with nail loading holes on the tray; a suture nail foot bending disc that mates with the nail carrier tray; a nail pusher sleeve drive mechanism connected to the right end of the nail pusher sleeve housing; a knife anvil located to the left of the suture nail foot bending disc; a knife anvil tightening adjustment mechanism connected between the knife anvil and the nail pusher sleeve drive mechanism; and a pair of blades embedded in the cavity wall of the nail pusher sleeve cavity, with the left blade protruding from the end of the nail pusher claw and corresponding to the nail carrier tray 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 limitation of inversion and adopts 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.

[0005] In addition, the staple cartridges in the aforementioned existing technologies all use a structure of direct suturing with staples. When suturing thicker labia, the staples are easy to get embedded in the labia, which not only causes pain to the patient, but also makes it difficult for the staples to fall off automatically, and also affects the appearance of the labia after recovery.

[0006] In view of the aforementioned problems, it is necessary to design a labial stapler with a cutting and suturing mechanism that can perform cutting and suturing while the labia are everted, and that can prevent suture staples from embedding into the labia. To this end, the applicant has ingeniously designed this technical solution. Utility Model Content

[0029] Please continue reading. Figure 1 , Figure 2When surgery is required, the labia are introduced into the position between the anvil plate 3 and the cutting and suturing mechanism 1 through the aforementioned anvil plate 3. The driving mechanism 2 is then operated to make the anvil plate 3 and the cutting and suturing mechanism 1 cooperate to clamp the labia. Then, the aforementioned driving mechanism 2 is operated to push the cutting pusher sleeve 12 forward. The aforementioned blade 14 passes through the corresponding blade relief groove 134 to cut the outer edge of the labia until it is completely against the anvil plate 3. At the same time, the aforementioned pusher teeth 124 extend into the staple cartridge 132 and push out the suture staples 1321 to suture the cut position of the labia. The aforementioned suture staples 1321 first pass through the suture staple pad 1331 and then through the labia. Finally, they are squeezed and bent on the anvil plate 3 and fixed at the wound. At this time, not only is the purpose of cutting and suturing completed simultaneously while the labia are everted, but also the method of the aforementioned suture staples 1321 passing through the suture staple pad 1331 before suturing effectively avoids the situation where the suture staples 1321 are embedded in the labia.

[0030] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the utility model task, and faithfully realizes the technical effects described by the applicant in the above-mentioned technical effects column.
