Background

The application of ultrasound is generally to convert or transmit ultrasonic energy into biological tissue through an end effect or surgical instruments, etc., to produce some physiological effect, particularly to cauterize, stop bleeding, cut tissue, etc., by using the generated heat. In a surgical instrument ultrasonic blade, a generator generates high frequency electrical energy, and a transducer converts the high frequency electrical energy into mechanical vibrations using piezoelectric or electromagnetically compressible materials, and amplifies the vibrations for transmission to a tip effector.

The ultrasonic scalpel in the current market has the following defects: firstly, when the cutter head performs mechanical oscillation to cut tissues at ultrasonic frequency, high heat is generated at the cutting position to gasify surrounding liquid, and the steam can shield a lens of an endoscope, so that the observation of the endoscope is influenced; secondly, when a plurality of surgical substances such as coagulants, proteins, blood, tissue particles and other component fluids exist near the cutter head, the surgical substances can be gradually coagulated to the surface of the cutter head along with the rise of the temperature, the use efficiency of the cutter head is further seriously influenced, even the cutter head is stopped due to the overload of the cutter head, and the observation visual field of the endoscope is also influenced by the excessive surgical substances.

Some ultrasonic knives with suction devices are available in the market for the above problems, but the ultrasonic knives also have the following disadvantages: firstly, the suction device and the ultrasonic knife are not integrally arranged, the operation progress is seriously influenced by frequently replacing the suction device and the operation instrument and scrubbing a lens, the operation time is prolonged, an independent instrument operation channel and space are occupied, the timeliness is poor, and the safety and the efficiency of the operation are not improved; secondly, the suction device is used for continuous negative pressure suction, which is easy to interfere the abdominal pressure to influence the exposure in the operation; third, the smoke is easy to disperse, the most important thing for removing is timely, and the timely and effective removal of the smoke and a small amount of bleeding in the prior art is difficult to realize synchronization.

In addition, in the prior art, most of the hemorrhages in the laparoscopic surgery are local small-amount hemorrhages, and special suction devices are not needed for treatment, because the suction devices are easy to suck surrounding tissues, the local small-amount hemorrhages and generated smog are not good, and special time is occupied when gauze is used for cleaning the visual field.
