Problems solved by technology

Surgeons usually use ultrasonic surgical instruments to cut tissue and coagulate tissue. However, in existing surgical operations, different energy devices are required for tissue stripping and hemostasis. Seriously affect the safety of surgical operations, and even lead to the failure of surgical operations, so it is particularly important to design an energy conversion device that can be used in ultrasonic surgical instruments

Abstract

The invention discloses a composite energy conversion device. An energy conversion PCB is provided with a signal receiving part for receiving a switching signal of an execution instrument and a signaloutput part connected with the execution instrument; an vibrator is provided with a piezoelectric ceramic part and an amplitude-change pole part connected with an execution instrument; two electrodesof the signal receiving part, the signal output part and the piezoelectric ceramic part are connected with an ultrasonic generator; the ultrasonic generator controls output switching of energy according to a switching signal, wherein the ultrasonic generator is connected with two electrodes of the piezoelectric ceramic part and outputs first energy to the execution instrument, and the ultrasonicgenerator is connected with one electrode of the piezoelectric ceramic part and the signal output part and outputs second energy to the execution instrument. The composite energy conversion device provided by the invention is mounted on the execution instrument in use, and realizes conversion and transmission of composite energy on the same execution instrument in the operation process, so that medical personnel can quickly select to perform corresponding tissue treatment when using the execution instrument, the operation efficiency and success rate are effectively improved, and patients are benefited.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a composite energy conversion device. Background technique [0002] Ultrasonic surgical instruments have been increasingly used in surgical operations due to their unique performance characteristics. Ultrasonic surgical instruments can be configured for open surgical use, laparoscopic or endoscopic surgical procedures, and depending on the specific instrument configuration and operating parameters, ultrasonic surgical instruments can facilitate tissue cutting and hemostasis with minimal trauma to the patient change. Surgeons usually use ultrasonic surgical instruments to cut tissue and coagulate tissue. However, in existing surgical operations, different energy devices are required for tissue stripping and hemostasis. Seriously affect the safety of surgical operations, and even lead to the failure of surgical operations, so it is particularly important to design an en...
