Abstract

A cutting and suturing mechanism of a labial cutting anastomat comprises an outer protective shell, a cutting nail pushing sleeve arranged in the outer protective shell, a nail bin sleeve installed at an opening of the outer protective shell and a pair of blades which are arranged between the outer protective shell and the cutting nail pushing sleeve and fixed to the cutting nail pushing sleeve. Two rows of nail bins are formed in the nail bin sleeve around the two sides of a nail bin sleeve cavity in an arc-shaped mode at intervals, suturing nails are arranged in the nail bins, suturing nail gasket grooves are formed in the positions, located on the two rows of nail bins, of the side face, away from the cutting nail pushing sleeve, of the nail bin sleeve, suturing nail gaskets are arranged in the gasket grooves, and a blade receding groove is formed in the position, corresponding to the blade, of the nail bin sleeve. When the cutting nail pushing sleeve moves forwards and pushes the suturing nail to act, the suturing nail can achieve suturing of the labia after penetrating through the suturing nail gasket. The device has the advantages that cutting and suturing can be completed at the same time under the condition that the labia is turned outwards, the operation difficulty is reduced, the situation that a suturing nail is embedded into the labia to cause pain to a patient is avoided, automatic falling of the suturing nail is facilitated, and the appearance after the labia is recovered is improved.

Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a cutting and suturing mechanism of a labiac cutting stapler. Background Art

[0002] With the progress of society, the medical industry is booming. Among them, the labia cutting and stapling device is an emerging medical device, which is mainly used for cutting and shaping the labia. Traditional labia shaping usually uses a scalpel or medical scissors for cutting. The operation and suturing process are very cumbersome and require high professional skills. In response to the above situation, some labia cutting and stapling devices have appeared on the market. They use tools to fix the labia and then use tools to quickly suture after the cutting is completed. The operation of these labia cutting and stapling devices is time-saving and labor-saving, and is generally recognized by the market. The cutting and suturing mechanism is the most core part of the labia cutting and stapling device. It is installed on the drive mechanism and is used to cut and sew the labia. When necessary, the labia cutting and suturing device can be reused by replacing the cutting and suturing mechanism. The current cutting and suturing mechanism usually adopts a structure in which suture staples are set in the staple magazine, and the driving mechanism pushes the cutting and suturing mechanism to push out the suture staples. The suture staples are generally in the structure of the character "[". After the two legs pass through the skin and flesh and bend the staples for suturing, the connection position between the two legs is often embedded in the skin and flesh due to the different thickness of the skin and flesh, which has an adverse effect on the appearance of the recovered labia.

[0003] In the prior art, for example, the "A Labiac Cutting and Stapling Device" disclosed in the Chinese invention patent authorization publication number CN111436990B includes a nail pushing sleeve protective shell, which has a nail pushing sleeve accommodating cavity and an elliptical left end; a nail pushing sleeve, which cooperates with the nail pushing sleeve accommodating cavity, has an elliptical left end and a nail pushing claw extending from the front and rear ends of the left end face, and a push-in and push-out mechanism is formed between the nail pushing claw in front of the left end face and the upper and lower parts of the nail pushing claw at the rear end face. A nail claw notch; a nail loading disc, arranged in the nail pushing sleeve accommodating cavity, with nail loading holes on the nail loading disc; a suture nail foot bending disc, cooperating with the nail loading disc; a nail pushing sleeve driving mechanism, connected to the right end of the nail pushing sleeve protective shell; a knife and anvil plate, located on the left side of the suture nail foot bending disc; a knife and anvil plate tightening and adjusting mechanism, connected between the knife and anvil plate and the nail pushing sleeve driving mechanism; a pair of blades, embedded in the cavity wall of the nail pushing sleeve cavity, with the blade edge on the left side protruding from the end of the nail pushing claw and corresponding to the nail loading disc cavity. Although this technical solution can complete the incision and suturing of the labia, it uses an inverted labia cutting and suturing structure. As is well known, the circumcision and suturing devices used an inverted structure when they were first invented. The above technical solution continues the cutting and suturing method of the traditional inverted circumcision device. The problems with this inverted structure in actual use are: due to the significant difference between labia cutting and circumcision, the labia are difficult to be stably fixed after inversion like the foreskin, and the inverted labia are difficult to observe after being fixed in the cutter and suturing device. Therefore, it is difficult for doctors to correctly judge the clamping state and cutting status of the labia, and the visual effect after labia cutting cannot be guaranteed, which fails to meet the needs of doctors and customers.

[0004] Another example is the "A Labia Suturing and Cutting Device" provided by Chinese invention patent authorization publication number CN111436989B, which includes a nail pushing sleeve protective shell, a nail pushing sleeve accommodating chamber and an elliptical left end; a nail pushing sleeve, which cooperates with the nail pushing sleeve accommodating chamber, has an elliptical left end, and has nail pushing claws on the front and rear sides of the left end face; a nail loading plate, which is elliptical and arranged in the nail pushing sleeve accommodating chamber, and has nail loading holes on it; a suture nail foot bending plate, which cooperates with the nail loading plate, and has a pit for the bent nail foot on its left side; a nail pushing sleeve driving mechanism, which is connected to the right end of the nail pushing sleeve protective 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 nail pushing sleeve driving mechanism. This technical solution breaks through the limitation of inversion and adopts a cutting and suturing structure of labia eversion, so that the labia are exposed on the outside of the suture cutter so that they can be observed. However, in actual operation, due to the change in the position of the labia, the blade originally located on the inside cannot cut the labia, and the doctor can only use a scalpel to manually cut on the outside of the suture cutter. The suture cutter can only fix the labia and sew, so it still cannot meet the needs of doctors and customers.

[0005] In addition, the staple cartridges in the above-mentioned prior art all adopt a structure of direct suturing with staples. For thicker labia, the staples are easily embedded in the labia during suturing, which not only causes pain to the patient, but also is not conducive to the automatic falling off of the staples, and also affects the appearance of the labia after recovery.

[0006] In view of the above problems, it is necessary to design a cutting and suturing mechanism of a labiac stapling device that can cut and sew the labia in an everted state and prevent the suturing staples from being embedded in the labia. To this end, the applicant has cleverly designed this technical solution. Summary of the Invention
