Problems solved by technology

[0005] During the operation, high-frequency current is required for electric cutting operation, and insulation is required for picking up objects. Due to this limitation, the existing electric snare and foreign object forceps can only enter the forceps channel separately, and cannot be used at the same time
Frequently switch between the electric snare and the foreign body forceps, that is, repeatedly inserting or pulling out the forceps, which not only prolongs the operation time, but also brings great inconvenience to the doctor's operation
At the same time, the excised polyps or tissues need to be recovered for pathological analysis. When the lesion tissue is resected, it will break away from the digestive wall and enter the digestive tract. At this time, if the instrument is switched, it is necessary to find and grab the resected lesion tissue, which not only prolongs the operation time, and there is a risk of not finding the lesion tissue

Description

【Technical field】 [0001] The invention relates to the technical field of medical instruments, in particular to a multifunctional electric cutting and recovery device applied to endoscopic surgery. 【Background technique】 [0002] With the popularization and improvement of endoscopic diagnosis and treatment technology, the application of ESD (endoscopic mucosal dissection), EMR (endoscopic mucosal resection), and polypectomy has gradually become popular. Commonly used diagnostic and therapeutic instruments include endoscopic injection needles, endoscopic spray tubes, electric snares, and foreign body forceps. [0003] The main purpose of the electric snare is to reach the lesion through the forceps of the endoscope, and after the tissue to be resected is taken, the high-frequency current is connected to realize the resection of the lesion. At the same time, the electric snare also has the function of tissue electrocoagulation and hemostasis. [0004] Foreign body forceps incl...
