Abstract

The invention provides an adjustable visual urethral dilator, and belongs to the technical field of medical instruments. The adjustable visual urethral dilator comprises a handle; an annular groove isformed in the right end of the handle; a feeler lever main body is fixed on the left inner wall of the annular groove; the upper end of the feeler lever main body is slidably connected with a drivingplate; a storage groove is formed in the upper end of the feeler lever main body; a limiting mechanism is arranged in the storage groove; the limiting mechanism is connected with the driving plate toachieve left-right linear motion of the driving plate; a plurality of first connecting plates are movably hinged between the front inner wall and the rear inner wall of the storage groove through a plurality of hinge shafts; and expansion plates are movably hinged to the upper ends of the first connecting plates through the hinge shafts. The urethral dilator is simple, easy to use, cheap, efficient and not prone to injuring an urethra in the using process.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an adjustable visual urethral dilator. Background technique [0002] At present, the incidence of male bladder cancer and prostate cancer in my country is increasing, and total cystectomy in situ neobladder and radical prostatectomy are one of the most important methods for the treatment of these two diseases. In these two operations, high-quality urethral anastomosis is the most critical step to ensure normal voiding function after urinary tract reconstruction. Usually, when performing urethral anastomosis, it is necessary to insert a urethral dilator in the distal urethra so as to play a guiding role during anastomosis. [0003] The traditional urethral dilator is blunt, round and solid. It is impossible for patients with too narrow urethra to enter, and it is prone to false tracts. It is very inconvenient to operate, and it is easy to cause damage to the p...
