Ultrasonic debridement surgical system

Abstract

The invention relates to an ultrasonic debridement surgical system which comprises a main machine, a debridement handle and a backpedaling brake. The surgical system is characterized in that the main machine comprises an ultrasonic signal control system and a fluid concentration / rate control system, wherein the ultrasonic signal control system comprises an ultrasonic signal generator and a frequency measuring and controlling device; the fluid concentration / rate control system comprises a fluid concentration generator and a rate / concentration measuring and controlling device; and the debridement handle comprises a transducer, an amplitude transformer and an ultrasonic debridement tool bar. By controlling the concentration and the rate of flushing fluid and the size of ultrasonic energy, the system can effectively perform debridement according to patient's condition, and is convenient for different trauma operations.

Description

technical field [0001] The invention relates to surgical medical equipment, in particular to an ultrasonic debridement operation system. Background technique [0002] In recent years, with the rapid development of the transportation industry, the increase in the frequency of natural disasters, the instances of diseased tissue infection and even ulceration, and the increase in sudden accidents, etc., the number of trauma cases is increasing year by year. Debridement is a kind of wound treatment Basic surgical operation has a significant effect on wound healing. Firstly, the contaminated wound is cleaned to eliminate bacteria and foreign matter in the affected area; secondly, the necrotic and lifeless tissue is excised, the wound is deeply sterilized, and the wound is cleaned. Whether the wound can be treated from the root will directly affect the healing of the wound, the recovery of the function and shape of the injured tissue, and so on. [0003] The application of ultras...

AI Technical Summary

Problems solved by technology

However, ordinary ultrasonic debridement machines have the following disadvantages: First, the structure of the ultrasonic debridement nozzle is single, and the debridement operation of some complicated parts cannot be completed, and it cannot meet the surgical requirements of different degrees of wounds.

Especially for some seriously infected or ulcerated wounds, the contaminated part cannot be removed from the root, so that harmful substances such as bacteria will continue to erode the healthy granulation tissue, and the goal of radical treatment cannot be achieved

Second, during the operation, the doctor needs to manually change the concentration and flow of the irrigation solution according to the degree of wound contamination, which makes the operation complicated

Third, the optimal design of the ultrasonic system of the debridement nozzle is not perfect, so that the ultrasonic cavitation and other effects cannot achieve the best effect
