Ultrasonic aspiration operation system capable of being controlled accurately

Abstract

An ultrasonic aspiration operation system capable of being controlled accurately structurally comprises an ultrasonic cutter (1), an ultrasonic handle (2) and a main machine (3). The ultrasonic cutter (1) is used for transmitting ultrasonic vibration. The ultrasonic handle (2) is connected with the ultrasonic cutter (1), converts ultrasonic frequency electrical signals into mechanical vibration, drives the ultrasonic cutter (1) to work, can detect the amplitude of the ultrasonic cutter (1) through a sensing piece, the amplitude is fed back to the main machine in an electrical signal mode, and the negative pressure and the power can be adjusted in a mechanical mode or an electrical signal mode. The main machine (3) gives ultrasonic frequency signals, drives the ultrasonic handle (2) to work, and can receive the amplitude, detected through the sensing piece, of the ultrasonic cutter (1) and adjust the output power according to the signals so as to control the output amplitude accurately.

Description

technical field [0001] The present invention relates to a surgical medical device, more specifically, to a precise controllable ultrasonic suction surgical system. Background technique [0002] The application of ultrasound is divided into detection ultrasound and power ultrasound. The application in medical treatment is mainly based on the three major effects of ultrasound, such as thermal effect, mechanical effect and cavitation effect, using its energy to change the structure, state and function of biological tissues. Such as ultrasonic surgical instrument, ultrasonic cleaning and ultrasonic focusing and so on. [0003] With the wide application of ultrasound, the ultrasonic suction system has also been produced and developed. The ultrasonic suction surgery system has a special hollow cutter that can radiate ultrasonic waves. Its cavitation effect crushes tumors such as the liver and brain, and then sucks out the surgical residue through negative pressure. Ultrasonic fr...

AI Technical Summary

Problems solved by technology

[0005] However, ordinary ultrasonic suction systems have the following disadvantages: First, ordinary ultrasonic suction systems do not have negative pressure and power adjustment functions, and can only use constant negative pressure and power that is set at the factory for surgery, and cannot adjust negative pressure and power. Adapt to the needs of different surgeries

Second, the amplitude of the ultrasonic cutter in the ordinary ultrasonic suction system cannot be precisely controlled, and excellent surgical results cannot be guaranteed
