A fixed-point crushing device and crushing method

Abstract

The invention belongs to the technical field of human body stone crushing, and particularly relates to a fixed point stone crushing device and crushing method.The fixed point stone crushing device comprises an ultrasonic cavitation generator and a conducting tube, and the ultrasonic cavitation generator is arranged at the end of the conducting tube; the conducting tube is of the flexible structure of which one end is closed and the other end is open, the closed end of the conducting tube is installed on the ultrasonic cavitation generator, a cavitation area is formed on the inner side near the closed end of the conducting tube, and the open end of the conducting tube is placed at a treated part.The fixed point stone crushing device and crushing method have the advantages that fixed point crushing on stones in a body is achieved through secondary cavitation, the stones can be discharged out of the body, the stones can be effectively treated, and no side effect is generated to the organism.

Description

technical field [0001] The invention belongs to the technical field of human calculus crushing, and in particular relates to a fixed-point crushing device and a crushing method. Background technique [0002] Stones are solid objects that form in luminal organs in the human or animal body. Stones can cause obstruction of the official cavity, hindering the drainage of organ fluid, accompanied by symptoms such as pain, bleeding or secondary infection. Present methods for the treatment of calculus include surgical treatment, extracorporeal lithotripsy, Western medicine treatment, Chinese medicine treatment and other methods. The most common is extracorporeal lithotripsy, including mechanical lithotripsy, electrohydraulic lithotripsy, ultrasonic lithotripsy, and laser lithotripsy. This method is not thorough and uneven, and has the possibility of breeding new stones, a high recurrence rate, and is destructive to surrounding body tissues and damages organ functions.

AI Technical Summary

Problems solved by technology

This ultrasonic lithotripsy technology is easy to damage organ functions, and the crushing is uneven and incomplete; in the prior art, a lithotripsy needle is used to crush the stones and then taken out. The lithotripsy probe used in this lithotripsy method has a complex structure , its cost is high and maintenance is difficult, the most important thing is that the existing lithotripsy probe is difficult to penetrate into the cavity, and it is easy to cause irreversible damage to the surrounding organs; the internal shock wave lithotripsy in the prior art is not only high in cost and complex in structure, And the impact process will cause damage to the body

[0004] Chinese patent CN 202113127 U discloses an ultrasonic ballistic lithotripsy treatment instrument, which includes a hydraulic expansion system for observing and finding stones in the ureter, an ultrasonic lithotripsy system, a negative pressure suction system, a pneumatic ballistic lithotripsy system and a control system, which can Pneumatic ballistic lithotripsy, ultrasonic lithotripsy, hydraulic expansion and negative pressure adsorption system are integrated into a four-in-one system, which can efficiently remove stone debris from the body while crushing stones. Its lithotripsy principle is the ultrasonic probe of the prior art , using primary cavitation gravel, and it is a complete system with high cost and complicated structure

Similarly, Chinese patent CN99119035 discloses a stone removal device with a probe for crushing stones, which also uses the shock wave of an ultrasonic probe to break stones, which is easy to cause damage to organs
