Surgical operating instrument and linear anastomat

Abstract

The invention relates to a surgical operating instrument and a linear anastomat. By arranging a nail pushing assembly and a percussion assembly, when an anastomosis mechanism is closed, the percussionassembly drives a first screw in the nail pushing assembly to rotate, and a percussion nut arranged on the percussion assembly in a sleeving mode moves in the first axis direction relative to the first screw, so that suturing nails in a nail bin are sequentially percussed, and the problems of large heads, small heads, dovetail and the like of the suturing nails are solved. Therefore, the surgicaloperating instrument and the linear anastomat adopt a sequential nailing mode, required percussion force can be saved so as to avoid deformation of nail anvils, and the surgical operating instrumentand the linear anastomat have a good nailing effect, a good suturing effect and good operation safety.

Description

technical field [0001] The invention relates to a surgical instrument and a linear stapler, which belong to the field of medical instruments. Background technique [0002] Linear stapler, also known as alimentary canal closure device, is a device that can insert multiple interlaced staples in a straight line on the tissue, and is also one of the devices widely used to replace manual linear suture. It is mainly used to suture the stumps of the stomach, duodenum, small intestine, and colon, and it is a full-thickness eversion suture. [0003] The staple forming method of the existing linear stapler is often to push the staple seat through the transmission device to push all the staples out at one time and fire them into staples, so that the staples are prone to large and small ends and dovetails, and the staple forming effect is poor, resulting in The sewing effect is not good, and it will cause waste at the same time. Moreover, due to the one-time firing of a large number o...

Problems solved by technology

[0003] The staple forming method of the existing linear stapler is often to push the staple seat through the transmission device to push out all the staples at one time and fire them into staples, so that the staples are prone to large and small ends and dovetails, and the staple forming effect is poor, resulting in The stitching effect is not good and at the same time it will cause waste

Moreover, due to the one-time firing of a large number of staples, some of the staples cannot be sutured firmly, which will cause tissue leakage and other situations; at the same time, because one-time firing is required, the firing force is relatively large, and the cantilever beam will be damaged after multiple firings. The anvil of the structure deforms
