Clamping tongs structure for ultrasonic surgical instruments

Abstract

The application provides a clamping tongs structure for ultrasonic surgical instruments and an ultrasonic surgical instrument with the clamping tongs structure. The clamping tongs structure comprisesa far end clamping part, wherein the far end clamping part consists of a first part located at the far end and a second part located at the near end; and the thickness of the first part is basically unchanged, the thickness of the second part is basically unchanged, and the thickness of the first part is smaller than that of the second part. The clamping tongs structure of the ultrasonic surgicalinstrument and the ultrasonic surgical instrument with the clamping tongs structure are favorable for layered cutting, careful cutting and blunt separation operations during clinical surgeries, so that the operation difficulty of doctors is alleviated, and the surgery efficacy is improved.

Description

technical field [0001] The present application relates to a surgical instrument, in particular to a clamp structure for an ultrasonic surgical instrument and the ultrasonic surgical instrument with the clamp structure. Background technique [0002] With the popularity of minimally invasive surgery, ultrasonic scalpel has become a routine surgical instrument. The ultrasonic scalpel uses an ultrasonic frequency generator to mechanically oscillate the blade at a certain ultrasonic frequency, vaporizes water molecules in tissues, breaks protein hydrogen bonds, and disintegrates cells, thereby cutting or coagulating tissues and making blood vessels closure. Ultrasonic scalpels enable simultaneous tissue cutting and coagulation with less lateral thermal damage. [0003] The ultrasonic scalpel is mainly composed of an ultrasonic frequency generator, a transducer and surgical instruments. Among them, the ultrasonic frequency generator sends out oscillating electrical signals, and...

Problems solved by technology

[0006] There is also a cutting head design that gradually becomes thinner from the proximal end to the distal end on the market, but clinically the cutting head cannot be used for layered cutting and fine separation, because the ultrasonic cutting head not only cuts the tissue that needs to be cut, Also cuts or causes thermal damage to unwanted tissue around the separation site

Based on the characteristics of the ultrasonic scalpel, the clamp needs to provide sufficient mechanical strength while providing a sufficiently thin thickness to ensure sufficient clamping force. The design that is directly thinned from the proximal end to the distal end cannot take into account both mechanical strength and thickness
