Abstract

The invention relates to a male urethra dilater with an endoscope, which 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, and a light cone is arranged in the optical fiber socket. 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 of simple operation, real-time observation, clear image and convenient use.

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] For traditional urethral dilators, the commonly used specifications are F16-F24. It is characterized by simple structure and low cost, but because it is a blind operation, the damage to the urethra and the generation of false tracts during dilation are unavoidable. Unfavorable results in long operation time, low operation quality and other adverse consequences...
