Interchanging lithotripter

Abstract

The invention relates to an interchanging lithotripter. An electrohydraulic treatment unit or an electromagnetic treatment unit is arranged in a spherical cavity housing component; through-holes are opened on the outer spherical cavity of the electrohydraulic treatment unit and the upper end surface of the electromagnetic treatment unit; via-holes are formed in the positions corresponding to the through-holes at the bottom of the spherical cavity housing component; hexagonal socket head cap screws are connected with the electrohydraulic treatment unit or the electromagnetic treatment unit via the through-holes or the via-holes; a connecting hole is arranged at the head end of a connecting rod; two L-shaped locating extended strips are arranged at the tail end of a locating cylinder; regulating hole groups are distributed on the locating extended strips; the connecting hole is connected with the regulating holes via bolt holes; screw threads are arranged in mounting holes, and threads corresponding to the threads of the mounting holes are arranged at the tail ends of triggering rods; the mounting holes and the triggering rods are in direct threaded connection; and auxiliary fixing blocks are connected to the tail ends of the triggering rods. By selecting the switching between the electrohydraulic treatment unit or the electromagnetic treatment unit as a shock wave source according to the requirements for practical application, the invention can achieve the interchanging effect.

Description

technical field [0001] The invention relates to a stone crusher, in particular to an interchangeable stone crusher, which belongs to the technical field of medical instruments. Background technique [0002] The extracorporeal shock wave lithotripter has been used for more than 20 years since the first one was used clinically, and it is known as one of the three major modern medical technologies (CT, MRI, TESWL). Its characteristics of safety, effectiveness, less pain and low cost have been widely used in the treatment of human urinary calculi, and have achieved very satisfactory results. So far, it has become the first choice for the treatment of urinary calculi. The shock wave source is the key core technology of the shock wave lithotripter, which determines the crushing effect of the stone, the biological response of the tissue, and the clinical work efficiency. At present, the shock wave sources used in extracorporeal shock wave lithotripters on the market mainly include...

Problems solved by technology

③ Piezoelectric shock wave is a kind of ultrashort wave pulse generated by circular piezoelectric crystal, which is characterized by compact and fine focus, but low energy, which is not as good as hydraulic shock wave

If the user (hospital) needs two kinds of shock wave sources in the clinical treatment process, it must introduce two lithotripsy machines with a single wave source, which is obviously unobjective and uneconomical. It also increases the economic burden of users. In my country, especially in the vast grassroots medical units, it is not realistic to have two lithotripters with a single wave source.
