Abstract

The invention discloses a rotatable and variable-speed electric snare handle. The rotatable and variable-speed electric snare handle comprises a handle main body, wherein the handle main body is sleeved by a ring sleeve in a sliding manner; a variable-speed gear and a transmission gear are respectively mounted on the ring sleeve and connected with the ring sleeve through locating pins; a first rack is arranged on the handle main body and in meshed connection with the variable-speed gear; the variable-speed gear is in meshed connection with the transmission gear; the transmission gear is in meshed connection with a second moveable rack; a turning wheel is mounted on the handle main body; a boosting rod is mounted in the turning wheel and connected with a copper sheet; the copper sheet is connected with a conductive column. The rotatable and variable-speed electric snare handle can reach the effect that an elastic metal wire can be rotated to enable a snare to snare a to-be-excised tissue, and the electric snare handle is convenient for a doctor to operate with a single hand.

Description

technical field [0001] The invention relates to medical equipment, in particular to a rotatable and variable speed electric snare handle. Background technique [0002] The electric snare is a commonly used medical device in laparoscopic surgery. It is mainly used for ligation of appendix remnants, gallbladder remnants, transfusion tubes and other cavity organs, as well as ligation of polyps in the rectum and sigmoid colon. The electric snare is used in conjunction with the endoscope, and high-frequency current can also be used to remove polyps or other redundant tissues in the digestive tract, which has the advantages of safety, convenience and economy. [0003] The basic structure of the existing electric snare device is as follows: a slippable finger ring is set on the tubular handle, the front end of the tubular handle is fixedly connected to the tail end of the flexible sheath, and the finger ring is connected to the end of the electrified elastic metal wire forming the ...
