AI Technical Summary

Technical Problem

Ultrasonic knife produces a lot of smoke when cutting coagulated tissue, causing lens field of view contamination, affecting surgical efficiency, and may cause thermal damage to adjacent tissues, increasing surgical risks.

Method used

A laminar ultrasonic knife is designed, including a generator, a transducer, an ultrasonic knife head, an attraction device, a first attraction tube and a second attraction tube. By setting an attraction channel in the head rod, the suction device absorbs smoke and heat, and filters impurities through the filter assembly to prevent contamination.

Benefits of technology

Effectively absorbing smoke and heat generated during laparoscopic surgery, reducing the impact on medical staff's operations, preventing thermal damage to adjacent tissues, simplifying connection operations, and improving surgical efficiency.

Abstract

The utility model discloses an endoscope ultrasound knife, including generator, transducer, ultrasound knife head, aspirator, first aspiration tube and second aspiration tube, generator, transducer and ultrasound knife head are connected in proper order, aspirator, first aspiration tube and second aspiration tube are connected in proper order, the first aspiration tube is connected in proper order, the second aspiration tube is connected in proper order, the first aspiration tube is connected in proper order, and the second aspiration tube is connected in proper order. The ultrasonic scalpel head comprises a handle and a rod body, when the ultrasonic scalpel head is used for endoscopic surgery, smoke and heat generated in the endoscopic surgery process are absorbed through the suction channel arranged in the rod body under the action of an aspirator, and due to the fact that the suction channel is arranged in the rod body and is close to the tail end, the smoke and the heat can be absorbed by the suction channel. According to the endoscopic surgery smoke and heat absorption device, smoke and heat in the endoscopic surgery process can be conveniently and timely absorbed, operation of a doctor is facilitated, meanwhile, heat damage to adjacent tissue is prevented, and the endoscopic surgery smoke and heat absorption device has the advantages of being high in practicability and having an absorption function.
