Electric resection ring with variable-size electrode

Abstract

The invention discloses an electric resection ring with a variable-size electrode. The electric resection ring comprises the electrode, delivery pipes and leads, wherein two ends of the electrode are connected with the leads and enter the delivery pipes from openings in the front ends of the delivery pipes, and the leads penetrate the delivery pipes and extend out from the tail ends of the delivery pipes. The electric resection ring can enter the operation position from the relatively small operation entrance, the size of the electrode of the electric resection ring is variable, and the tissue with the relatively large size can be cut only after a few times of resection; since the electrode is made of an elastic material with certain strength and toughness, the extension length of the electrode from the delivery pipes can be controlled by stretching the leads, and therefore, the size of the electrode is adjusted.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an electrocution ring with variable electrode size. Background technique [0002] When performing minimally invasive surgery, hysteroscopic surgery, nasal endoscopic surgery, etc., since the surgical site cannot be directly seen, it is usually performed with the help of various observation mirrors, such as laparoscopy, thoracoscopy, hysteroscopy, rhinoscopy, etc. When needing to carry out excision work in the operation, because the operation wound or the open mouth of human body organ are less, also can only use the lesser instrument of size. For example, when performing hysteroscopic myomectomy, the existing technology is: first use ring electrodes or rolling ball electrodes to electrocoagulate the large blood vessels on the surface of the fibroids and the blood vessels of the tumor pedicle, which can reduce intraoperative bleeding, and then extend the electrocoagulati...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the problem that the electrode size of the existing electric cutting ring is small, and when the size of the tissue to be cut is large, multiple cuts are required, and a kind of electric cutting ring with variable electrode size is developed. Small surgical access to the surgical site with variable electrode sizes enabling resection of larger tissue sizes in fewer passes
