Abstract

The present invention discloses an arbor with a replaceable blade, which is provided with an electric coagulation hemostasis function and is used in a laparoscopy urethra operation. The present invention includes a cylindrical operating lever. The front end of the operating lever is equipped with a tool apron, on which an operation blade can be installed. A scalable protection sleeve is arranged on the operating lever. The tool apron is a conductor. The outer surface of the operating lever is insulated. The tail part of the operating lever is equipped with a power input end, which is electrically connected with the tool apron via the inside part of the operating lever. The present invention is mainly applied to the nephrolithotomy under a laparoscopy.

Description

technical field [0001] The invention relates to medical equipment, in particular to a knife rod for laparoscopic ureteral surgery. Background technique [0002] At present, when doing laparoscopic ureterotomy for stone removal, an operation hole is usually arranged in the corresponding part of the patient, and then the ureteral wall is cut open with a built-in cold knife. When cutting the ureter with a cold knife, bleeding from small blood vessels at the cutting edge of the ureter may occur, affecting the field of vision. It is necessary to re-enter the electrocoagulation device to stop bleeding, and the blade cannot be replaced, and it will become blunt after repeated use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a knife rod for laparoscopic ureter surgery with replaceable blades. [0004] The further technical problem to be solved by the present invention is to provide a knife rod for laparoscopic urete...
