Electric anastomat with adjustable suture thickness

Abstract

The invention relates to the technical field of electric anastomats, and discloses an electric anastomat with adjustable suture thickness, which comprises an operation grab handle, a controller, a driving mechanism, a nail bin mounting part, a nail propping seat mounting part and a thickness detection mechanism; and a replaceable nail bin is installed in the nail bin mounting part, and an adjustable nail anvil assembly is installed in the nail propping seat mounting part. The thickness detection mechanism detects the actual intestinal wall thickness of the anastomosis part, and the controller adjusts the adjustable nail anvil assembly according to the actual intestinal wall thickness, so that the adjustable nail anvil assembly is matched with the replaceable nail bin, the forming height of the anastomosis nail is changed, and therefore, the final forming height of the suturing nail is matched with the thickness of the intestinal wall at the suturing position, the forming height of the suturing nail can be consistent with the thickness of the intestinal wall at the suturing position, it is guaranteed that the suturing nail can effectively press and close a thick blood vessel, meanwhile, the suturing nail is prevented from excessively extruding the tissue, and blood vessel injury and bleeding under mucosa at the anastomotic stoma are avoided.

Description

technical field [0001] The invention relates to the technical field of electric staplers, in particular to an electric stapler with adjustable suture thickness. 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, similar to a stapler. According to the scope of application, it can be divided into skin staplers, digestive tract circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, blood vessel staplers, hernia staplers, lung cutting staplers, etc. Among them, the intestinal stapler is a more commonly used circular stapler. [0003] In the actual use of the intestinal stapler, the intestinal tract of different patients, and the thickness of different positions of the intestinal tract of the same patient are all different. The Chinese patent of CN111466983B detects the stress between the nail bin and the nail anvil,...

AI Technical Summary

Problems solved by technology

[0007]Aiming at the deficiencies of the prior art, the present invention provides an electric stapler with adjustable suture thickness, which has the advantages that the forming height of the staples conforms to the actual intestinal wall thickness, etc. , Solve the problem that the height of the staples is not suitable and the anastomosis site is difficult to heal
