Background

As is well known, an ultrasonic scalpel, also called an ultrasonic scalpel, is a scalpel that gasifies human tissues by using high-frequency vibration of a scalpel head so as to achieve a cutting effect. When the ultrasonic knife works, the transducer converts an electric signal transmitted by the host machine into mechanical vibration, the mechanical vibration is transmitted to the knife head through the amplitude transformer, and the cutting action is completed after the knife head is contacted with human tissues. Because the principle of ultrasonic knife is that human tissue gasifies and realizes the cutting action, just so lead to ultrasonic knife can produce gas in the course of the work, these gases have certain toxicity mostly, and these toxic gases can cause harmful effects to patient's health if remain in patient.

In order to solve the problem, the chinese utility model patent with publication number CN209137792U discloses an ultrasonic scalpel for laparoscopic surgery with flushing and sucking functions, including handle piece, loop bar, ultrasonic tool bit, cutter arbor and ultrasonic transducer, the handle piece in be provided with ultrasonic transducer, the one end of cutter arbor fixed with ultrasonic tool bit, the other end and the ultrasonic transducer fixed connection of cutter arbor, the one end and the handle piece of loop bar be connected, the loop bar be provided with the cavity, ultrasonic tool bit set up the other end at the loop bar, the cutter arbor set up in the cavity of loop bar. The technical scheme can be used for absorbing and extracting the mist, blood and tissue fluid generated in the operation by connecting the negative pressure suction source with the negative pressure source.

However, it is well known that the blade or blade holder used in surgery needs to be disposable and replaced after use, and most ultrasonic blades have their handle and main body designed to be reusable in view of the cost of surgery.
