Urinary calculus crushing device for urinary surgery

The invention relates to the technical field of laser lithotripsy, and discloses a urinary calculus lithotripsy device for urinary surgery. Comprising a storage handle, an optical fiber guide lithotripsy drainage flexible channel which is stored in the storage handle and enters the bladder through an external urethral orifice, and a diameter expansion limiter which is arranged at the top of the optical fiber guide lithotripsy drainage flexible channel and prevents an inner diameter port of the optical fiber guide lithotripsy drainage flexible channel from shrinking; after inflation is conducted through an external air supply mechanism, the closed air cavity begins to expand at the moment, due to the action of air, the volume of the closed air cavity needs to be increased at the moment, then the everted pipeline is released, the everted pipeline is continuously affected by the diameter-expanding limiting device, the inner wall of the adduction pipeline is formed, and the length of the inner wall of the adducti
