Description

Urological urinary tract calculus lithotripsy device

Technical Field

The invention relates to the technical field of urinary calculus lithotripsy devices, in particular to a urinary calculus lithotripsy device for urinary surgery.

Background

Urinary tract calculus is a general term of calculus diseases at each part of the urinary system, is a common disease of the urinary system, and is divided into kidney calculus, ureteral calculus, vesical calculus and urethral calculus according to the difference of the parts where the calculus is located, and when the calculus in the urinary tract is taken out, the internal calculus is required to be observed firstly by using a urinary tract tube mirror, then the internal calculus is crushed by using a calculus crushing device, and then the crushed calculus residues are extracted, so that the calculus in the urinary tract of a patient is taken out, and therefore, the conventional urinary tract calculus breaking device for urinary surgery basically meets the use requirements of people, but still has some problems.

When the existing urinary calculus lithotripter breaks stones, the breaker is required to be inserted into the urinary bladder firstly, then stones entering the urinary tract are broken, but when the urinary tract is broken, as the urinary tract is narrow, when the size of the stones is large, the breaking knife can damage the inner wall of the urinary tract in the breaking process, and broken residues can collide with the inner wall of the urinary tract simultaneously, so that the urinary tract is damaged, and the usability and applicability are reduced;

secondly, when the calculus inside the urinary tract is broken, calculus residues can scatter in the urinary tract, the calculus residues are not easy to collect, and when the calculus residues are collected, a large amount of time is wasted, meanwhile, the patient is damaged, the calculus is not completely treated, the calculus is continuously remained in the urinary tract, the calculus appearing condition of a patient again can be possibly caused, and secondary pain is brought to the patient, so that the novel urinary tract calculus lithotripter for urinary surgery is needed to solve the problems.
