Auxiliary light source of ultrasonic scalpel

Abstract

The invention relates to an auxiliary light source of an ultrasonic scalpel, belonging to surgical operating instruments. In ordinary surgical operations, the ultrasonic scalpel is generally used for carrying out operations such as tissue separation, and the like, but when abdominopelvic cavity deep part operations or perineum operations are carried out, operative field lighting is difficult, which causes operation difficulties and risks. Aiming to solve the problem, the invention ensures that the auxiliary light source can be conveniently fixed on the rod of the ultrasonic scalpel and turned on through a design of a clamping groove of a small electric torch, a light gathering cover and a switch capable of being fixed and moves along with the ultrasonic scalpel to lighten a scalpel head operation area so as to provide good operative field lighting in deep part operations.

Description

technical field [0001] The invention relates to a surgical instrument, which is an auxiliary light source specially designed for an ultrasonic knife, and is used for illumination of the operation field when the ultrasonic knife performs deep surgery. Background technique [0002] At present, ultrasonic scalpel has been widely used in surgical operations. In abdominal surgery, ultrasonic scalpel is often used for deep operations in the abdominal cavity, pelvis or perineum, such as intrapelvic operations in radical resection of rectal cancer, and anus resection in Mile's surgery for rectal cancer. It is narrow and difficult to expose the operative field, and the shadowless light above the operating table is difficult to ideally illuminate the operative field, resulting in a dim operative field, difficult operation, and easy damage to blood vessels or other tissue structures. Contents of the invention [0003] In order to solve the lighting problem when using the ultrasonic ...
