Intraperitoneal wound suturing device based on anvil block position feedback

Abstract

The invention discloses an intraperitoneal wound suturing device based on anvil block position feedback. The intraperitoneal wound suturing device mainly comprises an extending pipe, a supporting block, an operating mechanism and a suturing mechanism. The suturing mechanism comprises an arc-shaped fixing strip connected to the interior of the bottom end of a connecting rod shell and provided withan arc-shaped sliding groove, an arc-shaped suture needle arranged in the sliding groove in a sliding manner; a push block and a pull block accounting for half of the width of the sliding groove, arranged in the sliding groove in the sliding mode and assisting the suture needle in completing the suture period; a sewing wheel arranged at the circle center of the fixing strip, a first jacking columnarranged on the sewing wheel and used for pushing the push block, a second jacking column arranged on the sewing wheel and used for pushing the pull block, a reset spring arranged on the side face ofthe push block and the side face of the pull block, and a first ramp and a second ramp are used for separating the first jacking column from the push block as well as separating the second jacking column from the pull block. During suturing, secondary injury to wounds of patients can be reduced, and the suture needle is convenient to operate and suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of intra-abdominal wound suturing, in particular to a device for suturing intra-abdominal wounds based on anvil position feedback. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery. Greatly increased surgical options. The traditional method of retroperitoneal laparoscopic surgery is to make three small incisions of 1 cm on the patient's waist, each inserting a tube-shaped working channel called "trocar", and all subsequent operations are performed through these t...

Problems solved by technology

[0003] The current suture device requires several suture tubes to be inserted for suture. If suture is needed in a special position, more openings need to be made on the patient, and the shaking of each suture tube may cause the wound to dehisce, resulting in surgical risks. , and if the suture tube is inserted too much, it will block the view, and suture requires two or more clamp bars to cooperate, need to clamp the suture needle - puncture - another clamp bar clamps the needle of the suture needle - pull out - exchange suture Needling to the previous forceps rod is extremely troublesome and consumes a lot of energy for the doctor
