Disposable digestive tract intelligent stapler and usage method thereof

Abstract

The invention discloses a disposable digestive tract intelligent stapler. The staple cartridge assembly includes an integrally arranged nail pushing piece and an annular knife, and a staple cartridge arranged at the front end of the nail pushing piece. 3 pressure sensors; the method of use includes disconnecting the nail anvil assembly from the staple cartridge assembly; inserting the nail anvil assembly into the tissue to be sutured with a purse, tightening the purse, and then inserting the anvil assembly with the guide The shaft is docked; after the docking is completed, when the distance between the end face of the staple cartridge and the lower end face of the abutment seat is between K~S, the pointer in the indicator window is displayed in the safe green area, and the observation window displays the pressure When the data of the sensors are all within the range of P±P1, the green light of the indicator light is on, and the tissue can be anastomosed. Through the above-mentioned method, the present invention can completely eliminate the risk of anastomotic leakage caused by blind and improper operation of the stapler, and realize the revolution of surgical digitalization.

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
