Debridement device for general surgery

Abstract

The invention relates to a debridement device for general surgery, comprising a main body, a debridement ejection head and a connecting pipe connected between the main body and the debridement ejection head. The main body is provided with a debridement liquid pump for mixing debridement liquid of different components according to a set proportion and pressurizing and delivering the debridement liquid to the debridement ejection head. The debridement liquid pump comprises three pumping assemblies, a driving mechanism for driving the pumping assemblies and a nozzle connected with the liquid outlet end of the pumping assemblies; the pumping assembly comprises a diaphragm pump, a debridement tank, a suction pipe and a high-pressure pipe; the debridement device of the invention reasonably setsthe position of the transducer and the fulcrum of the horn, can improve the electric/acoustic conversion efficiency, and at the same time can accurately and automatically adjust the composition of thedebridement liquid according to the demand.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a debridement device for general surgery. Background technique [0002] When medical personnel perform wound debridement and disinfection on patients, they often use traditional methods to directly wash and disinfect the patient's wound. Due to the complexity of the external environment, it is easy to cause cross-infection in the affected part of the patient, which is not conducive to the recovery of the patient's wound; [0003] Existing studies have shown that using the cavitation effect of ultrasonic waves to flush wounds with water flow loaded with ultrasonic waves can effectively eliminate wound bacteria without causing serious damage to wounds. Therefore, there are already some medical ultrasonic waves in the prior art. cleaning machine, but the existing ultrasonic cleaning machine is not perfect enough, and has some shortcomings, such as: the connection structure...

[0002] When medical personnel perform wound debridement and disinfection on patients, they often use traditional methods to directly wash and disinfect the patient's wound. Due to the complexity of the external environment, it is easy to cause cross-infection in the affected part of the patient, which is not conducive to the recovery of the patient's wound;

[0003] Existing studies have shown that using the cavitation effect of ultrasonic waves to flush wounds with water flow loaded with ultrasonic waves can effectively eliminate wound bacteria without causing serious damage to wounds. Therefore, there are already some medical ultrasonic waves in the prior art. cleaning machine, but the existing ultrasonic cleaning machine is not perfect enough, and has some shortcomings, such as: the connection structure between the horn and the shell is unreasonable, resulting in low electric / acoustic conversion efficiency, resulting in excessive heat generation, easy to burn tissue, A cooling mechanism needs to be installed on the horn

In addition, when performing debridement treatment at present, the finished product or pre-configured debridement solution is usually selected according to the actual situation of the patient for debridement, but the operation of the existing debridement machine to replace the debridement solution is not convenient enough, and it is impossible to use it according to the actual situation. Automatically configure debridement solution with appropriate ingredients on the spot
