A kind of flexible uretero-nephroscope

Abstract

The present invention relates to a surgical instrument. A uretero-nephroscope with a bendable head end, comprising an operating body connected with a mirror tube, the operating body includes a mirror body connected in sequence, an assembly and disassembly mechanism, and a telescoping mechanism; the mirror tube includes an insertion part, a bending part and The tip part; wherein the insertion part is connected with the mirror body, and a sheath is connected outside the mirror tube. The length of the sheath is shorter than that of the mirror tube. The telescopic mechanism is located at one end of the sheath tube. The present invention provides a device that can take both soft and hard parts into consideration, and can be assembled and disassembled quickly, so as to facilitate the disinfection of various parts, easy to insert the ureter, and can smoothly enter each renal calices, especially the lower calices, and can well observe the situation in the lower calices. A uretero-nephroscope with a bendable head end; it solves the problem that the ureteroscope in the prior art is difficult to insert into the ureter, cannot observe the situation in the lower cup well, and can effectively perform diagnosis and treatment, and at the same time, the components cannot be quickly assembled, disassembled and sterilized question.

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
