Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical devices, and particularly relates to a labia minora fixing mechanism of a labia minora cutting anastomat. BACKGROUND

[0002] With the progress of society, the medical industry is booming, and the labia minora cutting anastomat is a new medical device, which is mainly used for cutting and shaping the labia minora. The traditional shaping of the labia minora usually adopts a surgical knife or a medical scissors for cutting operation, and the operation and suturing process is very cumbersome, and has a high requirement for professional technology. Therefore, some labia minora cutting and suturing devices appear on the market, which fix the labia minora by tools and quickly suture after cutting. The labia minora cutting and suturing device is time-saving and labor-saving, and is generally recognized by the market. The tool for fixing the labia minora is a labia minora fixing mechanism, which can be divided into two types of internal turning type fixing and external turning type fixing according to different cutting methods of the labia minora.

[0003] In the prior art, a labia minora cutting and suturing device is disclosed in Chinese Patent No. CN111436990B, which comprises a push nail sleeve shell having a push nail sleeve accommodating cavity and an oval left end; a push nail sleeve cooperating with the push nail sleeve accommodating cavity, the left end of which is oval-shaped and the front and rear of the left end face each extend a push nail claw, and the upper and lower parts between the push nail claw in front of the left end face and the push nail claw behind the left end face each form a push nail claw gap; a nail loading disc provided in the push nail sleeve accommodating cavity, the nail loading disc being provided with a nail loading hole; a suturing nail foot bending disc cooperating with the nail loading disc; a push nail sleeve driving mechanism connected with the right end of the push nail sleeve shell; a knife anvil plate located on the left side of the suturing nail foot bending disc; a knife anvil plate tightening adjusting mechanism connected between the knife anvil plate and the push nail sleeve driving mechanism; and a pair of knife blades embedded in the cavity wall of the push nail sleeve cavity, the left blade edge of which protrudes from the end of the push nail claw and corresponds to the cavity of the nail loading disc. Although the above technical solution can cut and suture the labia minora, it adopts an internal turning type labia minora cutting and suturing structure. As known, the foreskin cutting and suturing device uses an internal turning type structure when it is first invented, and the above technical solution follows the cutting and suturing method of the traditional internal turning type foreskin cutting device. However, there are some problems in the actual use of the internal turning type structure. Since there is a big difference between the labia minora cutting and the foreskin cutting, the labia minora is difficult to be fixed stably after being turned inward like the foreskin, and the turned-in labia minora is difficult to be observed after being fixed in the cutting and suturing device. Therefore, it is difficult for doctors to correctly judge the clamping state and cutting condition of the labia minora, and the appearance effect after cutting the labia minora cannot be guaranteed, so the above technical solution cannot meet the needs of doctors and customers.

[0004] For example, the Chinese invention patent authorization publication No. CN111436989B provides a "labia suturing cutter", which includes a push nail sleeve shell with a push nail sleeve containing cavity and an oval left end; the push nail sleeve is matched with the push nail sleeve containing cavity, the left end is oval, and the front and back of the left end surface has a push nail claw; the nail loading disc is oval and is arranged in the push nail sleeve containing cavity, and the nail loading hole is arranged on the nail loading disc; the suturing nail foot bending disc is matched with the nail loading disc, and the left side has a bent nail foot pit; the push nail sleeve driving mechanism is connected with the right end of the push nail sleeve shell; the labia guiding positioning plate is located on the left side of the suturing nail foot bending disc; the labia guiding positioning plate tightening adjusting mechanism is connected between the labia guiding positioning plate and the push nail sleeve driving mechanism. The technical scheme breaks through the limitation of inversion and adopts the labia everted cutting and suturing structure, so that the labia is exposed on the outside of the suturing cutter and can be observed, but in actual operation, the position of the labia is changed, the blade originally located on the inside cannot cut the labia, and only the doctor can manually cut the labia on the outside of the suturing cutter with a scalpel, and the suturing cutter can only fix the labia and suture, so it still cannot meet the needs of doctors and customers, in addition, the labia everted guiding positioning plate for guiding the labia can make the labia evert and fix, but in actual use, it is found that the difficulty of introducing the labia is relatively large, and the labia is flattened when everted, which is not conducive to plastic beautification.

[0005] In view of the above problems, it is necessary to design a labia fixing mechanism of a labia cutting anastomat which can make the labia evert, reduce the difficulty of introducing the labia, and keep the everted arc of the labia. Therefore, the applicant ingeniously designs the technical scheme. SUMMARY
