Positioning device used for digestive tract lesion endoscope

Abstract

A positioning device used for a digestive tract lesion endoscope comprises a positioning assembly used for marking inside a digestive tract and a detection assembly used for positioning outside the digestive track, wherein the positioning assembly used for marking inside the digestive track comprises a vertical pipe, a semispherical shell with a convex surface facing upwards is fixedly installed at the upper end of the vertical pipe, a liquid inlet hole is formed in the top of the semispherical shell, a motor installation plate is fixedly installed at the lower end of the vertical pipe, a battery is fixedly installed at the top of the motor installation plate, and a second round plate is disposed on the lower side of the motor installation plate. The positioning device determines a digestive tract lesion position through swallowing of the endoscope, an output shaft of a driving motor is controlled to rotate forwards and thus a rack pushes a rectangular elastic skin to make contact withthe inner wall of the digestive tract, so that the positioning assembly is stopped, the lesion position can be further determined, a medical worker can find the accurate lesion position on the outerside of the digestive tract through the detection assembly, and the rack pushes a piston block to continuously push out a medicine liquid to lesion tissue so as to treat a patient.

Description

technical field [0001] The invention belongs to the field of endoscope positioning devices for gastrointestinal lesions, in particular to a positioning device for gastrointestinal lesions endoscopes. 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, that is, the endoscope can locate the lesion in the patient's body, but the doctor cannot see or touch the lesion from the outside of the patient's body, nor can he determine the lesion's location, scope and relationship with surrounding tissues. Inaccurate preoperative positioning may mislead the surgeon. Repeated detection of the lesion during the operation will not only prolong the operation time, but also increase the chances of tumor spread, implant meta...

Problems solved by technology

[0002] Laparoscopic minimally invasive treatment technology is widely used clinically, and has replaced traditional laparotomy in the treatment of many diseases, achieving good curative effect, quick recovery, minimally invasive The ideal goal of healing, but there is a big defect in laparoscopic technology, especially non-hands-assisted laparoscopic surgery, that is, the endoscope can locate the lesion in the patient's body, but the doctor cannot see or touch it from the outside of the patient's body The location of the lesion, the location, extent and relationship with the surrounding tissues cannot be determined. Inaccurate preoperative positioning may mislead the surgeon. Repeated detection of the lesion during the operation will not only prolong the operation time, but also increase the risk of tumor spread, implantation metastasis, bleeding and infection. In severe cases, it may even lead to miscut lesions. Therefore, accurate positioning of gastrointestinal lesions is very important for the selection of surgical methods, incisions and body positions. Most of the lesion positioning devices in the prior art are marked by titanium clips, but due to the disease Individual differences and the technical level of surgeons are uneven. Once there is an error and the wrong choice of surgical incision occurs, very difficult surgical complications will occur, which limits its widespread promotion, and the use of general endoscopes to determine the location of lesions in patients makes patients It causes great pain, and the current practical clinical application urgently needs the emergence of new products to solve the current predicament
