Ureter nephroscope with bendable head end

Abstract

The invention relates to a surgical instrument. A ureter nephroscope with a bendable head end comprises an operating body which is connected with a nephroscope tube. The operating body comprises a nephroscope body, an assembling and disassembling mechanism and a retractable mechanism all of which are sequentially connected. The nephroscope tube comprises an inserting part, a bending part and a head end part all of which are sequentially connected. The inserting part is connected with the nephroscope body, the nephroscope tube is sleeved with a sheathing tube, the length of the sheathing tube is smaller than that of the nephroscope tube, and the retractable mechanism is located at one end of the sheathing tube and is connected with the nephroscope body through the assembling and disassembling mechanism. The ureter nephroscope with the bendable head end integrates the functions of a hard ureter nephroscope and a soft ureter nephroscope, and can be fast mounted and dismounted so that all components can be disinfected conveniently, the ureter nephroscope can be inserted into the ureter easily and can be inserted into kidney calices, especially into the lower kidney calices smoothly, and the situation inside the lower kidney calices can be well observed. The technical problems that an existing ureterocope in the prior art is inserted into the ureter difficultly, the situation inside the lower kidney calices cannot be well observed, the treatment cannot be well carried out, and the components cannot be fast mounted, dismounted or disinfected are solved.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a uretero-nephroscope for clinical inspection, diagnosis and treatment of urethra and kidney stone diseases. Background technique [0002] Human urinary system calculus is a kind of common disease, frequently-occurring disease. Stones can be divided into bladder stones, ureteral stones, and kidney stones according to the location of the stones. Speaking from the probability of occurrence, kidney stones account for more than 70%. Stone removal surgery can be divided into: extracorporeal ultrasonic lithotripsy, intracavitary ballistic lithotripsy, percutaneous nephroscopy, transurethral ureteral nephroscopy, etc. From the analysis of lithotripsy effect, doctor and patient acceptance, surgical risk and complication rate, trauma and recovery time, transurethral ureteroscopy has certain advantages. It has become the main treatment method for upper urinary tract stones in hospitals. The usu...

Problems solved by technology

[0004] At the same time, the present invention also provides a kind of uretero-nephroscope capable of working with circulating water, reducing the perfusion pressure in the kidney, convenient for observation, good in lithotripsy effect and high in stone crushing efficiency; it solves the problems existing in the prior art It is impossible to circulate water in and out, easily damage the glomerulus, and the technical problem of stone crushing efficiency is not high
