Suture instruments for laparoscopic surgery

Abstract

The invention discloses a stitching apparatus used for the laparoscopic surgery, relating to the field of surgical instruments for the laparoscopic surgery. The stitching apparatus comprises a control mechanism, a regulating mechanism and a stitching mechanism, wherein the control mechanism comprises an operating handle; T-shaped sliding chutes pointing to the axial line are uniformly distributed in the operating handle along the circumferential direction; a sliding positioning device is arranged in each sliding chute; the regulating mechanism comprises a deformable sleeve connected with the rear end of the operating handle; control lines corresponding to the sliding positioning devices in a one-to-one correspondence manner are arranged in the wall of the deformable sleeve along the axial direction; the stitching mechanism comprises a work sleeve in sleeving connection with a connecting shaft; a microwave heating ring is arranged on the rear end of the work sleeve; and C-shaped stitching devices uniformly distributed are arranged between two limiting grooves along the axial direction. The stitching apparatus has the beneficial effects that the operating angle is adjustable, and the collagen package is adopted, therefore, the rejection reaction of the human body is reduced, the labour of medical staff is reduced, and the operation is simple, efficient, safe and reliable.

Description

technical field [0001] The invention relates to the field of laparoscopic surgical instruments. Background technique [0002] Laparoscopic surgery has been greatly developed, and laparoscopy with minimally invasive effects plays an important role in the diagnosis and treatment of abdominal diseases. In order to reduce the workload of medical staff and reduce the bleeding time, etc., it is necessary to quickly suture the wound. The traditional simple and efficient stapler-type stapler uses metal staples to push into the tissue, but it fails to solve the problem of human body rejection. Some hidden dangers, some improved staplers have improved safety performance, but the operation is complicated, and the purely manual mechanical operation method also affects the accuracy and other issues that must be considered. Many staplers are linear, and the angle cannot be changed, which often conflicts between the operating angle and viewing angle, which affects the operation of medical...

In order to reduce the workload of medical staff and reduce the bleeding time, etc., it is necessary to quickly suture the wound. The traditional simple and efficient stapler-type stapler uses metal staples to push into the tissue, but it fails to solve the problem of human body rejection. Some hidden dangers, some improved sutures have improved the safety performance, but the operation is complicated, and the purely manual mechanical operation method also affects the accuracy and other issues that must be considered.

Many staplers are linear, and the angle cannot be changed, which often conflicts between the operating angle and viewing angle, which affects the operation of medical staff, and also makes it difficult to suture at some inconvenient angles, or requires multiple operations on the skin. causing pain to the patient
