Problems solved by technology

[0004] In the actual work of the ultrasonic scalpel, as the working time increases, the distal end of the outer sleeve heats up and becomes hot. Since the protein may be denatured above 70 degrees, at this time the temperature of the outer sleeve exceeds 70 degrees, which leads to tissue protein denaturation, resulting in heat damage

Abstract

The invention discloses an ultrasonic scalpel. The ultrasonic scalpel comprises a shell, a sleeve connected to the shell and a scalpel rod arranged in the sleeve, and is characterized in that the sleeve is provided with a heat insulation area. In the actual work of the ultrasonic scalpel, the far end of the outer sleeve is heated and scalded along with the increase of the working time, but the sleeve is provided with the heat insulation area, so that the heat damage of tissues is avoided.

Description

technical field [0001] The present disclosure generally relates to the field of medical ultrasonic surgery, and specifically relates to an ultrasonic knife. Background technique [0002] Ultrasonic surgical devices are used in a variety of applications in surgery due to their unique performance characteristics. Depending on the particular device configuration and operating parameters, ultrasonic surgical devices are capable of substantially simultaneous tissue transection and hemostasis by coagulation, thereby advantageously minimizing patient trauma. The ultrasonic surgical device includes a proximally positioned ultrasonic transducer and an instrument coupled to the ultrasonic transducer, the instrument having a distally mounted end effector including an ultrasonic knife to cut and seal tissue. The end effector is typically coupled to the handle and / or robotic surgical tool via a shaft. The blade is acoustically coupled to the transducer via a waveguide extending through...
