Handheld ultrasonic knife

Abstract

The invention discloses a handheld ultrasonic knife. The handheld ultrasonic knife comprises an ultrasonic knife body, a limiting assembly, a first sliding groove, a second sliding groove, a third infusion tube and a controller, a fixing handle is fixed to the ultrasonic knife body, a first storage battery is embedded in the fixing handle, and meanwhile the ultrasonic knife body is rotationally connected with a movable handle; a connecting pipe is fixed to the ultrasonic knife body, a storage tube is fixed to the connecting pipe, the limiting assembly is fixed to the storage tube, a supporting assembly is slidably connected to the limiting assembly, the first sliding groove and the second sliding groove are formed in the connecting pipe, an auxiliary clamping assembly is slidably connected into the first sliding groove. The second sliding groove and a second sliding way mechanism form a sliding structure, and one end of the third infusion tube communicates with the storage tube. The handheld ultrasonic knife has the advantages that peripheral tissue can be protected, smoke generated during an operation can be treated, generated blood can be treated, and the ultrasonic knife body can be supported.

Description

technical field [0001] The invention relates to the technical field of ultrasonic scalpels, in particular to a hand-held ultrasonic scalpel. Background technique [0002] Ultrasonic cutting hemostatic knife, referred to as ultrasonic knife, is mainly used for laparoscopic surgery. The ultrasonic scalpel has the advantages of less damage to the surgical site or surrounding tissues, less bleeding, and clear vision. The ultrasonic scalpel has a strong coagulation function, which makes the treatment of the omentum and mesentery and the separation of adhesions easier. An ideal cutting hemostatic tool. [0003] When the existing hand-held ultrasonic scalpel is in use, due to the high temperature of the ultrasonic scalpel, if the surrounding tissue is not treated well, it is easy to damage the surrounding tissue. When the ultrasonic scalpel is working, the smoke is not processed quickly, which affects During laparoscopic surgery, the field of view and the bleeding during ultrason...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a hand-held ultrasonic knife to solve the problem that when the existing hand-held ultrasonic knife proposed in the above-mentioned background technology is in use, due to the high temperature of the ultrasonic knife, if the surrounding tissues are not treated well, It is easy to damage the surrounding tissues. When the ultrasonic scalpel is working, the smoke is not processed quickly, which affects the vision during laparoscopic surgery. At the same time, when the bleeding occurs during the ultrasonic scalpel operation and is not treated in time, it also affects the correct judgment of the medical staff and affects the quality of the operation. Problems causing unnecessary harm to patients
