Abstract

The invention relates to a nested flexible ureteroscope. The nested flexible ureteroscope comprises a rod-shaped optical fiber scope provided with a long-fiber-shaped image transmitting scope body, atubular handheld handle and a bendable sheath, wherein the tubular handheld handle and the bendable sheath are communicated with each other. An image-transmitting optical fiber is arranged in the scope body, and a driving steel wire for controlling the bending extent of the bendable sheath is inserted into the bendable sheath; a windowing sliding groove is formed in the outer wall face of the handheld handle in the length direction of the handheld handle, a bending-causing pushing handle is slidingly arranged on the windowing sliding groove and connected to the proximal end of the driving steel wire, and the distal end of the driving steel wire and the side wall of the bendable sheath are fixed; the optical fiber scope is inserted into the handheld handle through an optical-fiber-scope insertion hole in the tubular tail end of the handheld handle, and the scope body is inserted into the bendable sheath. The nested flexible ureteroscope has the advantages that the structure is easy andconvenient, the cost is low, operation is convenient, an additional scope sheath product is avoided, and the nested flexible ureteroscope can be applied to various surgeries for which ureteroscopes and flexible ureteroscopes are suitable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a nested flexible ureteroscope. Background technique [0002] The flexible ureteroscope currently on the market is a medical device product that can be used independently. Due to its small diameter, complex structure, and high processing and manufacturing technology threshold, the cost of use and maintenance is high; in addition, the flexible ureteroscope in the prior art The flexible ureteroscope sheath is usually required to be used in conjunction with the mirror. Because the mirror sheath is relatively thick, it is often necessary to insert a ureteral stent into the patient's ureter to dilate the ureter before the operation. To sum up, the existing flexible ureteroscopy technology has many disadvantages. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and solve the problems of the existing ure...
