Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a unilateral labial cutting stapler. Background Technology

[0002] With the increasing societal demand for women's reproductive health and aesthetics, labiaplasty is becoming increasingly widely used in clinical practice. Traditional labiaplasty often relies on surgeons manually cutting with scalpels or medical scissors, supplemented by sutures for hemostasis and closure. This method is not only cumbersome and time-consuming, but also highly dependent on the surgeon's experience and skills, resulting in drawbacks such as excessive bleeding, irregular wounds, slow postoperative recovery, and difficulty in guaranteeing aesthetic results. To improve surgical efficiency and standardization, in recent years, specialized integrated cutting and suturing instruments for labiaplasty have gradually appeared on the market: labiaplasty staplers. These instruments draw on the design concept of circumcision staplers, using mechanical structures to simultaneously fix, cut, and suture the labial tissue, significantly shortening surgical time and reducing operational difficulty.

[0003] More importantly, existing labial staplers generally adopt a design concept of bilateral symmetrical synchronous cutting and suturing, that is, to treat both sides of the labia at the same time in one operation. However, in clinical practice, a considerable number of patients have unilateral labial hypertrophy or abnormal shape, and only one side of the labia needs to be reconstructed, while the other side does not need intervention. In such cases, the use of traditional bilateral synchronous instruments will not only cause unnecessary clamping, damage or even accidental cutting of the healthy side of the tissue, but may also destroy the original natural shape due to forced symmetrical operation, which violates the principle of individualized and precise plastic surgery.

[0004] 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, having a pusher sleeve receiving cavity and an elliptical shape on the left end; a pusher sleeve, which cooperates with the pusher sleeve receiving cavity, having an elliptical shape on the left end and pusher claws extending from the front and rear of the left end face, with 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 staple carrier tray is located within the staple pusher sleeve cavity, and the staple carrier tray has staple holes; a suture pin bending disc mates with the staple carrier tray; a staple pusher sleeve drive mechanism is connected to the right end of the staple pusher sleeve housing; a knife anvil is located to the left of the suture pin bending disc; a knife anvil tightening and adjusting mechanism is connected between the knife anvil and the staple pusher sleeve drive mechanism; a pair of blades are embedded in the cavity wall of the staple pusher sleeve cavity, with the left blade protruding from the end of the staple pusher claw and corresponding to the staple carrier tray cavity; (Example: Chinese invention patent) The "Labia Suturing Cutter" disclosed in CN111436989B includes a pusher sleeve housing 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, also having an elliptical shape at the left end and pusher claws at the front and rear of the left end face; a elliptical staple tray located within the pusher sleeve receiving cavity, with staple holes on it; a suture staple foot bending tray, which cooperates with the staple tray and has a recess for bending staple feet on its left side; a pusher sleeve driving mechanism connected to the right end of the pusher sleeve housing; a labia guide positioning plate located to the left of the suture staple foot bending tray; and a labia guide positioning plate tightening adjustment mechanism connected between the labia guide positioning plate and the pusher sleeve driving mechanism. Both of the above-mentioned publications are instruments suitable for simultaneously cutting both sides of the labia. However, when dealing with unilateral cutting, the healthy labia tissue may be unnecessarily clamped, damaged, or even accidentally cut.

[0005] In view of the aforementioned problems, it is necessary to design a unilateral labial anastomosis device that is simple in structure, easy to operate, and capable of cutting either side of the labia individually. To this end, the applicant has ingeniously designed this technical solution. Summary of the Invention

[0031] Please continue reading. Figures 1 to 4When surgery is required, first rotate the aforementioned anvil tightening and adjusting mechanism 7 in the reverse direction. Push out the screw 641 through the threaded hole 71 to disengage the anvil 6. Then, pass the labia requiring reshaping through the labia guide groove 611 on the same side of the anvil 6 from the front side of the anvil 6. Use tweezers to flip the labia outward from the position between the anvil 6 and the staple cartridge sleeve 4. The healthy labia on the other side rest against the front side of the anvil body 61. Next, rotate the aforementioned anvil tightening and adjusting mechanism 7 in the forward direction. Pull the screw 641 and pull rod 64 through the threaded hole 71 to move the anvil 6 towards the staple cartridge sleeve 4 until the anvil 6 and staple cartridge sleeve 4 clamp one side of the labia. The clamping state of the labia can be clearly observed, and the position of the labia can be adjusted to change the cutting position. At this time, the aforementioned knife and anvil limiting strip 6121 is embedded in the knife and anvil limiting groove 412, so that the knife and anvil 6 is kept stable on the nail cartridge sleeve 4. Finally, the aforementioned safety pin 10 is pulled out and the handle 9 is pressed hard. The aforementioned handle 9 rotates around the handle shaft 131 and pushes the push rod 91, so that the top body 8 slides forward in the drive sleeve hole 11. The aforementioned top body 8 pushes the cutting push nail sleeve 3 forward. The aforementioned blade 35 passes through the corresponding blade clearance groove 43 to cut the outer edge of the labia until it is completely against the knife and anvil 66. At the same time, the aforementioned push nail teeth 34 extend into the nail cartridge 42 to push out the suture nail 421. The aforementioned suture nail 421 passes through the adhesive strip 422 to suture the cut position of the labia. The aforementioned suture nail 421 is bent and fixed at the wound under the combined action of the bent nail groove 652 and the push nail teeth 34. After the surgery is completed, the handle 9 is pried open in the opposite direction, causing the push rod 91 to pull the top body 8 to slide backward in the drive sleeve hole 11. The top body 8 pulls the cutting pusher sleeve 3 to move backward, causing the blade 35 to retract into the outer protective shell 2, thereby avoiding secondary damage to the blade 35. Finally, the aforementioned knife and anvil tightening adjustment mechanism 7 is rotated in the opposite direction, causing the knife and anvil 6 to disengage and release the clamping state on the labia, thus completing the entire surgical process.

[0032] In summary, the technical solution provided by this invention makes up for the shortcomings of the prior art, successfully completes the invention task, and accurately realizes the technical effects described by the applicant in the above technical effects column.
