Surgical stapler with device for adjusting spacing between sewing nails

Abstract

The invention relates to the technical field of surgical staplers, and discloses a surgical stapler with a device for adjusting the spacing between sewing nails. The surgical stapler comprises a shell, wherein a nail bin and a grip are arranged in the shell, and the grip is arranged on the left side of the nail bin. According to the surgical stapler, by rotating a rotating part, the rotating part can drive sliding rods to extend out through clamping columns, when the sliding rods extend out to a proper distance for stapling, a connecting frame is extruded to drive a first pressing rod and a second pressing rod to extrude the sliding rods, therefore, rotating plates can make contact with the rotating part, the rotating plates are clamped by elastic plates, the two sliding rods can be clamped through the rotating plates at the upper end and the lower end, and the sliding rods are prevented from being extruded and retracted; and when the extending distance of the sliding rods needs to be adjusted, an adjusting strip is inserted into an opening, the two rotating plates at the upper end and the lower end can be pulled back into a groove, the extending distance of the sliding rods can be adjusted again, and the purpose of adjusting the spacing between the sewing nails is achieved.

Description

technical field [0001] The invention relates to the technical field of surgical staplers, in particular to a surgical stapler with a device for adjusting the distance between staples. Background technique [0002] In recent years, surgeons have increasingly used stapling instruments to staple body tissue such as the lungs, esophagus, stomach, duodenum, and / or other organs within the intestinal tract. The use of appropriate stapling instruments on many occasions allows for better operations in less time and simplifies previously difficult surgical procedures such as gastrointestinal anastomosis. Existing linear two-row and four-row cutter staplers include cartridge-free instruments into which staples are individually manually loaded. Other existing devices include pre-sterilized disposable staple loading units and cutting members that can be used to divide tissue and simultaneously form multiple rows of staples.

Problems solved by technology

[0003] The surgical stapler in the prior art is used directly when in use, and the spacing of the staples cannot be adjusted, and it can only be stapled to a wound of a specific size, which is highly restrictive, so we propose a device with Surgical stapler for adjusting staple spacing device
