Disposable intelligent alimentary canal anastomat and application method thereof

Abstract

The invention discloses a disposable intelligent alimentary canal anastomat. A nail bin assembly comprises a nail pushing sheet, an annular knife and a nail bin, the nail pushing sheet and the annular knife are integrally arranged, the nail bin is arranged at the front end of the nail pushing sheet, and at least three pressure sensors are uniformly distributed in the nail bin. The application method includes the steps that a nail abutting base assembly is disconnected from the nail bin assembly; the nail abutting base assembly is inserted into tissue to be sutured and with a packet, the packet is tightened, and the nail abutting base assembly and a guide shaft are in butt joint; after butt joint is completed, the distance between the end face of the nail bin and the lower end face of a nail abutting base is between K and S, a pointer in an indication window is displayed in a safe green area; when data, displayed by an observation window, of all the pressure sensors are within the range of P+ / -P1, a green light of an indicator light is turned on, and the tissue can be anastomosed. In this way, the risk of anastomotic leakage caused by improper and blind operation of the anastomat can be thoroughly eliminated, and a surgery digitization revolution is achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable digestive tract intelligent stapler and a method for using the same. Background technique [0002] Anastomotic leakage is the most common serious complication after surgery and the leading cause of death, and anastomotic leakage is still the most serious complication. It has been reported in the literature that the incidence of anastomotic leakage after esophageal cancer surgery is 3%-5%, and the mortality rate is 50%. The incidence of colonic anastomotic leakage is 5-10% in China, and the mortality rate is 1 / 3. Therefore, postoperative anastomotic leakage is still an urgent problem to be solved, and its prevention and proper treatment are of the greatest significance for reducing postoperative complications and operative mortality. However, improper anastomotic technique is still the main cause of anastomotic leakage, and the stapler is the main link of anastomotic ...

AI Technical Summary

Problems solved by technology

[0003] The defects of the traditional stapler are: the tightness of the tissue in the anastomotic mouth is judged entirely by the operator's hand feeling (that is, the tightness of the nut is adjusted by rotating)

Different doctors, different parts and different patients may cause misjudgment and lead to the formation of anastomotic leakage due to lack of accurate theoretical data

It cannot accurately reflect the uneven distribution of tissues at the anastomotic stoma, which may cause doctors to misjudge and lead to the formation of anastomotic leakage

Different staplers and staplers produced by different manufacturers may have different hand feel, which may cause doctors to misjudge and lead to the formation of anastomotic leakage
