Reducing type electric intracavity anastomat without replacing nail bin

Abstract

The invention relates to the field of anastomats, and discloses a variable-diameter electric intracavity anastomat without replacing a nail bin, according to the suture density requirement of a to-be-sutured tissue, a micro motor is controlled to operate, and corresponding moving rods are indirectly driven to move in the horizontal direction, so that the distance between the adjacent moving rods is changed, and the suture density of the to-be-sutured tissue is changed. The distance between the nail storage plates is indirectly changed through linkage of the connecting blocks, the distance between the multiple sets of anastomosis nails is adjusted, the suturing density is changed, the situation that due to the fact that the traditional suturing density is consistent, tissue fluid is difficult to discharge after suturing is avoided, the postoperative risk is reduced, in addition, the driving motor can be controlled to operate according to the width of a to-be-sutured area, and the suturing efficiency is improved. The nail storage plate and the anastomosis nails on the nail storage plate are deflected, so that the arrangement width of the anastomosis nails is changed in the section direction, the suturing width is changed on the premise that a nail bin piece does not need to be replaced, the operation time is saved, the operation risk is reduced, and the practicability of the anastomat is further improved.

Description

technical field [0001] The invention relates to the field of staplers, in particular to a variable-diameter electric intracavity stapler that does not need to replace a staple cartridge. Background technique [0002] Endovascular cutting stapler, as a medical device that replaces manual cutting, is widely used in a variety of open and minimally invasive general surgery, obstetrics and gynecology, urology, thoracic surgery and pediatric operations. An endoluminal cutting stapler usually includes a stapler body and a cutting assembly. Different cutting assemblies have different cutting strokes. During the operation, it is necessary to select a cutting assembly with a different cutting stroke according to the type and location of the cut tissue. [0003] In the prior art, the Chinese patent document with the publication number CN112353443B discloses a staple cartridge assembly, a nail felt assembly, a fixed block, a stapler and an assembly method thereof. The staple cartridge a...
