Electric anastomat with adjustable suture caliber

Abstract

The invention relates to the technical field of electric anastomats, and discloses an electric anastomat with an adjustable suture caliber, the electric anastomat comprises an operation grab handle, a controller, a nail abutting seat assembly and a nail bin assembly, the nail abutting seat assembly comprises a caliber detection unit and a telescopic nail anvil unit, and the nail bin assembly is internally provided with an adjustable nail bin. The central lifting disc drives the independent nail bins to synchronously move along the rails correspondingly arranged on the sliding variable-diameter ring, the diameter of the anastomosis ring is adjusted so that the diameter of the anastomosis ring can be matched with the initial inner diameter, and the ejection position of the ejection assembly is adjusted through the controller according to the diameter of the ring layer, so that the anastomosis is completed. The annular nail anvil jacked by the jacking assembly can directly face a plurality of independent nail bins forming a current anastomosis ring, so that the suture caliber of the electric anastomat is matched with the diameter of an actual intestinal tract of a patient in a natural state, and the situation that the suture caliber is too large or too small, and adverse effects are caused to healing of the intestinal tract of the patient is avoided.

Description

technical field [0001] The invention relates to the technical field of electric staplers, in particular to an electric stapler with adjustable suturing diameter. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues. According to the scope of application, it can be mainly divided into digestive tract circular staplers, rectal staplers, lung cutting staplers, etc. Among them, intestinal staplers are more commonly used circular staplers. [0003] In the actual use of the intestinal stapler, the intestinal tracts of different patients and different positions of the intestinal tract of the same patient have different calibers in the natural state. After the stapler is sutured, the intestinal tract returns to its natural state due to its own elasticity. At this time, if the diameter of the staples sutured by the stapler does not match the natural diamete...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an electric stapler with adjustable suturing caliber, which has the advantages of high suturing precision and the ability to adjust the diameter of the sutured circle, and solves the problem of the staple diameter and intestinal tract sutured by the stapler. Mismatch in the natural diameter of the gut, making it difficult for the gut to heal quickly
