A urethral dilation and catheterization device with visualization

Abstract

The invention discloses a visualized urethral dilating and urinary catheterization device, which comprises a hollow catheter and a guiding part. The telescopic mechanism fixedly connected with it, the telescopic mechanism is provided with a number of connecting rods, the connecting rods and the outside of the telescopic mechanism are covered with hoses, one end of the flexible pipe is fixedly connected with the guide part, The other end of the hose is fixedly connected to the hollow conduit, and the hollow conduit is used to place an observation mirror, and the observation mirror is embedded in the guide part, and the end of the guide part and the guide part The ends of the urine mechanism are all flush with the ends of the observation mirror, and the device can realize visual operation, safely and reliably perform urethral dilation or indwell a catheter, and reduce the risk of urethral (secondary) injury.

Description

technical field [0001] The invention relates to a medical device, in particular to a visualized urethral dilation and catheterization device. Background technique [0002] In the clinical work of urology, if the patient has urethral stricture, urethral injury, benign prostatic hyperplasia and acute urinary retention, urethral dilatation and / or indwelling catheterization may be performed according to the actual situation. Because traditional urethral dilatation or catheterization is performed under non-visual conditions, it is impossible to judge the normal running direction of the urethral cavity, and it is difficult to understand the specific situation of the urethral injury site and urethral stricture. As a result, the above-mentioned operation lacks a sense of direction, is relatively blind, and is prone to failure. In the end, it has to be diverted to a more invasive cystostomy, or even an open operation to restore the continuity of the urethra. Not only that, the above...

Problems solved by technology

Because traditional urethral dilatation or catheterization is performed under non-visual conditions, it is impossible to judge the normal running direction of the urethral cavity, and it is difficult to understand the specific situation of the urethral injury site and urethral stricture. As a result, the above operations lack a sense of direction, are relatively blind, and are prone to failure. In the end, they have to be diverted to more traumatic cystostomy, or even open surgery to restore the continuity of the urethra

Not only that, the above-mentioned operations under non-visualization may increase the risk of urethral (secondary) injury, and even form a urethral false tract, with many complications and very painful for the patient
