AI Technical Summary

Technical Problem

The existing incision suturing device has a poor kneading effect when suturing the vaginal stump and cannot effectively knead the tissues on both sides of the vaginal stump, resulting in inconvenience in suturing.

Method used

A vaginal closure device for laparoscopic hysterectomy is designed. It includes a support plate, a stump kneading component, a pulling component, a stump twisting component, and a needle threading component. Through the coordinated action of an electric push rod and a rotary motor, the vaginal stump is kneaded in a "Z" shape and then converted into an "S" shape, ensuring a smooth and beautiful suturing process.

Benefits of technology

The invention realizes the effective kneading and suturing of the vaginal stump, simplifies the suturing steps, improves the efficiency and effect of suturing, and avoids the inconvenience of manual operation.

Abstract

The invention provides a vaginal closer for hysterectomy under a laparoscope, and belongs to the technical field of medical instruments. In order to solve the problems that an existing incision suture device is poor in kneading effect and inconvenient to suture, the vagina closer for the hysterectomy under the laparoscope comprises a supporting plate, two stump kneading assemblies, two traction assemblies, two stump twisting assemblies and a needle threading assembly, and the two stump kneading assemblies, the two traction assemblies, the two stump twisting assemblies and the needle threading assembly are arranged on the supporting plate. When the vagina closing device is used, the anastomat is used for anastomosing the vagina stump under the direct vision of a laparoscope, the vagina closing device is placed in the vagina through the handheld rod, then the two stump kneading assemblies are used for kneading the vagina stump, and then the two traction assemblies are used for pulling open the two kneading assemblies respectively; and the two twisting assemblies rotate the two kneading assemblies in opposite directions, so that the anastomosed vagina stump is kept in an S-shaped kneading state, the subsequent needle threading assembly drives a suture needle to suture, the suture is smoother, and the suture steps are simplified.
