Medical extracorporal shock wave lithotriptor

Abstract

The invention discloses a medical extracorporal shock wave lithotriptor. The medical extracorporal shock wave lithotriptor comprises a base, a standing column is fixedly connected to the base, an operating bed is fixedly installed to the standing column, grooves are formed in the left edge and the right edge of the upper surface of the operating bed respectively, conveying belts are arranged in the grooves, vertical rods are fixedly connected to the conveying belts, air sacs are fixedly connected to the vertical rods, ventilating grooves are formed inside the vertical rods, and an air pump isfixedly connected to the ventilating grooves; a machine box is fixedly connected to the base, a rotating disc is arranged on the side, opposite to the operating bed, of the machine box, an X-directionmechanical arm and a Y-direction mechanical arm are fixedly connected to the rotating disc, and shock wave focusers are installed at the tail end of the X-direction mechanical arm and the tail end ofthe Y-direction mechanical arm. As the multiple adjustable air sacs are arranged, the posture and the position of a patient are fixed, the flexible body position when the patient is operated is achieved, and the comfortable degree is improved; as the two mutually-perpendicular shock wave focusers are arranged, the lithotripsy efficiency is improved through the rocky anisotropy.

Description

technical field [0001] The invention relates to the technical field of lithotripters, in particular to a medical extracorporeal shock wave lithotripter. Background technique [0002] Extracorporeal shock wave lithotripter is a medical machine that uses shock waves to focus and position crushed stones. According to different extracorporeal shock wave generators, it is divided into three types: hydraulic shock wave, electromagnetic shock wave and piezoelectric shock wave. The currently used medical extracorporeal shock wave lithotripsy The machine has the following disadvantages: [0003] (1) Most of the currently used medical extracorporeal shock wave lithotripters use a flat operating bed to allow patients to lie flat or prone on the operating bed. This fixing method is suitable for patients with stones in the abdomen or near the back. If If the stone grows on the side of the patient, the patient is required to lie on the side on the operating bed, and it is difficult to ma...

AI Technical Summary

Problems solved by technology

[0003] (1) Most of the currently used medical extracorporeal shock wave lithotripters use a flat operating bed to allow patients to lie flat or prone on the operating bed. This fixing method is suitable for patients with stones in the abdomen or near the back. If If the stone grows on the side of the patient, the patient is required to lie on the side on the operating bed, and it is difficult to maintain a still position when lying on the side on the operating bed. Maintaining a position for a long time and not being able to relax will make the patient feel uncomfortable and affect the operation;

[0004] (2) The principle of the shock wave of the currently used medical extracorporeal shock wave lithotripter is to focus the generated shock wave on a point through a convex lens, and position the focus on the stone in the patient's body, and then generate continuous and rapid alternating stones through the shock wave. Compressive stress and tensile stress, so as to crush the brittle stones. The existing medical extracorporeal shock wave lithotripter has only one shock wave source. Although it is easy to control, the efficiency is extremely low and the time is long;

[0005] (3) The focused alluvial waves produced by the currently used medical extracorporeal shock wave lithotripter can only be directed in one direction. However, for rocks, they generally have anisotropy, and their mechanical properties in different directions are often different. The efficiency of crushing is different, and the existing medical extracorporeal shock wave lithotripter does not take this into account
