Extracorporeal shock wave lithotripter

Abstract

The invention relates to an extracorporeal shock wave lithotripter which comprises a lithotripsy bed and a shock wave source device. A bed frame is arranged beside the lithotripsy bed, a circular guide rail is arranged on the bed frame, the shock wave source device is arranged on the circular guide rail, the lithotripsy bed is positioned inside the circular guide rail, a horizontal guide rail is arranged on the bed frame, the lithotripsy bed is positioned on the horizontal guide rail, a control end is arranged on the bed frame, the shock wave source device is driven to slide on the circular guide rail through a motor, the lithotripsy bed is driven to slide on the horizontal guide rail through the motor, and the control end controls the motor to rotate. By the aid of the structure, multidirectional lithotripsy operation can be realized, needed effects can be achieved without rotating the bed, the extracorporeal shock wave lithotripter is safe to use and simple to operate, time and labor are saved, and the burden of medical workers is reduced.

Description

technical field [0001] The invention relates to a medical device in the medical technology industry, in particular to a shock wave extracorporeal lithotripsy machine. Background technique [0002] Extracorporeal shock wave lithotripsy (ESWL) is to generate shock waves through an extracorporeal lithotripsy machine, which is focused on the stones by the machine, and the stones in the body are crushed after multiple releases of energy, so that they are excreted with urine. The basic principle of shock wave generation (hydraulic electricity) is to form a high-energy-density, high-temperature, high-pressure plasma area on the discharge channel through high voltage, high current, and instantaneous discharge, and quickly convert electrical energy into heat energy, light energy, force energy and sound. Yes, the discharge channel expands rapidly during the discharge process, forming a pressure pulse in the water medium, that is, a shock wave. [0003] The adjustable range of the hea...

AI Technical Summary

Problems solved by technology

[0003] The adjustable range of the head of the traditional lithotripter is relatively small. It is difficult to find a suitable angle when treating patients with special lesions. The treatment effect is often unsatisfactory, and it also brings great difficulty to the medical staff.
