Length-adjustable purse anastomat

Abstract

The invention provides a length-adjustable purse anastomat. The purse anastomat comprises a left connecting rod, a right connecting rod, a connecting pin, a left handle, a right handle, a first connecting rod, a second connecting rod, a rotating assembly, a first clamping handle, a second clamping handle, a nail abutting seat assembly, a nail bin assembly, a lifting assembly, a buckle and a safety assembly, wherein the heights of the first clamping handle and the second clamping handle can be adjusted through changing the position of the connecting plate in an adjusting hole, so that the length of a whole purse anastomat can be freely changed; when the position of a sutured tissue is relatively deep, the nail abutting seat assembly and the nail bin assembly can make contact with the tissue to be sutured by changing the length; and inclined angles between the first connecting rod and the right connecting rod and between the second connecting rod and the left connecting rod can be adjusted by rotating a rotating block on a rotating seat, so that angles between the nail abutting seat assembly and the left handle and between the nail bin assembly and the right handle can be changed. The purse anastomat is adjusted to an angle by rotating the rotating block when reaching the position of the tissue to-be-sutured at the certain angle.

Description

technical field [0001] The invention relates to the technical field of medical suturing, in particular to a purse purse stapler with adjustable length. Background technique [0002] Purse string suture, also known as pocket suture, is mainly used for continuous suture around the opening. While turning the tissue or stump inward from the purse, the suture is tightened and knotted. It is mainly used for embedding, which can reduce pollution and To promote healing, it is suitable for embedding small holes and stumps on the broad ligament in obstetrics and gynecology operations; it is often used for suturing small holes on the bladder wall in urological operations, or for human small intestine, colon, and rectum in clinical surgery. It is a common method for temporary closure of physiological tissues such as esophagus and esophagus. The original purse-string suture mainly uses purse-string forceps and needs to be used together with the accessories with needle suture. Although th...

[0002] Purse string suture, also known as pocket suture, is mainly used for continuous suture around the opening. While turning the tissue or stump inward from the purse, the suture is tightened and knotted. It is mainly used for embedding, which can reduce pollution and To promote healing, it is suitable for embedding small holes and stumps on the broad ligament in obstetrics and gynecology operations; it is often used for suturing small holes on the bladder wall in urological operations, or for human small intestine, colon, and rectum in clinical surgery. It is a common method for temporary closure of physiological tissues such as esophagus and esophagus. The original purse-string suture mainly uses purse-string forceps and needs to be used together with the accessories with needle suture. Although this structure can complete the purse-string suture, the operation process is relatively cumbersome and requires manual threading. , correspondingly prolonged the operation time and tested the proficiency of the operator. For this reason, a purse-string stapler integrating staples and sutures appeared, and the purse-string suture can be completed by firing the clamping forceps once, which greatly improves the efficiency of the purse-string suture.

[0003] The publication number is CN106236168B, which provides a purse-string stapler with replaceable staple cartridges. Although it uses the integrated design of staples and sutures, the purse-string suture can be completed by firing the clamping forceps once, but there are still the following deficiencies: 1. The length of the stapler is fixed and cannot be adjusted independently. When the position of the stitched tissue is relatively deep, it often occurs that the stitching parts of the current stapler cannot reach the stitched tissue; 2. The stitched parts and the handle The angle between them cannot be adjusted freely. When there is a certain angle between the suture position and the operation position, the operation is troublesome and the scope of application is narrow; Vertical angle, such an angle of use takes up a lot of space when tightening the sutures to tie the purse, and the operation is very inconvenient
