Novel endoscopy positioning device for digestive tract lesion

Abstract

The invention relates to a novel endoscopy positioning device for digestive tract lesion and belongs to the field of medical instruments. On the basis of the space distribution characteristics of a magnetic field, the specific position of an in-vivo positioning mechanism is detected by means of magnetic force generated through mutual action of inside and outside magnetic fields of a human body; and the device comprises the in-vivo positioning mechanism, an in-vitro detecting mechanism and a display mechanism. A magnetic detecting rod which can enter an abdominal cavity from an opening formed in an abdominal wall by means of a laparoscope is adopted for detecting the suspicious lesion location of a digestive tract cavity; when a magnetic metal clip is detected, an electromagnetic switch of the detecting rod can be triggered, an indicator lamp is turned on, the lesion location is determined, generally, 2-3 magnetic metal clips can be placed on the opening side and the anus side of lesion for marking, the lesion range boundary is determined, and the problem of difficulty in positioning of lesion under the laparoscope is fundamentally solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a novel endoscopic positioning device for gastrointestinal lesions. It is used to explore the abdominal cavity and check suspicious lesions. When the magnetic metal clip is detected, the electromagnetic force switch of the detection rod will be activated, and the indicator light will be turned on. It is an in vivo positioning tool that can confirm the lesion and its boundary. Background technique [0002] Laparoscopic minimally invasive treatment technology is widely used clinically, and has replaced traditional laparotomy in the treatment of many diseases, achieving the ideal goal of good curative effect, fast recovery, and minimally invasive cure. There is a major defect in endoscopic surgery-the lack of tactile sense; the operator cannot check by hand touch like open surgery to determine the location, scope and relationship with surrounding tissues of the lesion.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new endoscopic positioning device for gastrointestinal lesions, which solves the most contraindicated and difficult situation in surgical laparoscopic surgery - the location of the lesion that needs to be resected and the scope of surgical resection cannot be found or clarified during the operation. A magnetic detection rod that can enter the abdominal cavity through the laparoscopic abdominal wall stoma to detect the digestive tract and cavity of suspicious lesions. When the magnetic metal clip is detected, the electromagnetic force switch of the detection rod will be activated, and the indicator light will be turned on. To confirm the lesion site, generally 2-3 pieces of magnetic metal clips will be placed on the mouth side and anal side of the lesion to mark, confirm the boundary of the lesion, and fundamentally solve the problem of locating the lesion under laparoscopy
