Abstract

The invention relates to a male urethra dilater with an endoscope, and the diameter of the dilater can be changed. The dilater comprises a base, a straight mirror canal, a bent mirror canal, a dilatation head, an optical fiber socket, a water injection port and an image interface, the dilatation head is a solid and transparent cone the end of which is spherical; a lens, an image transmission bar,a light transmitting bundle and a aqueduct are arranged in the straight mirror canal and the bent mirror canal; the bent mirror canal is sheathed with a dismountable dilatation sheath the outer diameter of which can be changed, and the shades which are coupled each other and become a three-dimensional cross are arranged in the dilatation head. The male urethra dilater solves the technical problems that the existing male urethra dilater is restricted in use when male urethra is narrow and visibility of the entire urethra can not be reached, and has the advantages that operation is simple, the dilatation sheath can be replaced conveniently, image is clear, use is safe, and cross infection can be prevented effectively.

Description

technical field [0001] The invention relates to a male urethral dilator, in particular to a male urethral dilator with an endoscope. Background technique [0002] Male urethral dilator is a basic medical tool in urological surgery. It is used in the examination and diagnosis of male urethral diseases, urethral reunion due to urethral injury caused by trauma, transurethral dilation of the prostate, prostatectomy and trauma, In the treatment of urethral stricture caused by various reasons such as prostatectomy, and in the prevention of urethral stricture after hypospadias urethroplasty, the range is very wide. [0003] The traditional urethral dilator, commonly used in specifications of F16-F24, is characterized by simple structure and low cost. However, because it is a blind operation, the damage to the urethra and the generation of false tracts during dilation are unavoidable, so it has relatively high technical requirements for doctors, and it will cause long operation tim...
