Embodiment Construction

[0014] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, a high-pressure balloon olecranon urethral dilator includes a dilator body 1 and a high-pressure balloon 2 . The upper end of the dilator body 2 is provided with a finger pulp recess 11, which is used for the thumb grip of the operator during operation. The direction of the dilator is turned indiscriminately to avoid damage to the urethra and rectum. The lower end of the dilator body 1 is provided with an olecranon-shaped elbow 12 . The inside of the dilator body 1 is provided with introduction holes running through both ends thereof. The high-pressure balloon 2 is arranged on the dilator body 1 and is located on the upper part of the olecranon-shaped elbow 12 . Such as figure 2 As shown, the angle A between the tangential direction of the olecranon-shaped elbow 12 and the length direction of the dilator ...

Abstract

The invention discloses a high-pressure balloon olecranon-shaped urethral dilator which comprises a dilator body and a high-pressure balloon. A finger pulp concave part is arranged at the upper end of the dilator body. An olecranon-shaped elbow is arranged at the lower end of the dilator body. A lead-in hole penetrating through the two ends of the dilator body is formed in the dilator body. The high-pressure balloon is arranged on the dilator body and located on the upper portion of the olecranon-shaped elbow. The included angle between the tangent line direction of the olecranon-shaped elbow and the length direction of the dilator body ranges from 30 degrees to 45 degrees. The high-pressure balloon is arranged on the dilator body and can be expanded in sequence, a guide wire is placed in a bladder through the urethrostenosis part under an endoscope, the high-pressure balloon olecranon-shaped urethral dilator is guided by the guide wire to be placed in any narrow part of a urethra for expansion, operation is easy and convenient, urethrostenosis part can be rapidly expanded, and therefore complications such as bleeding and injuries during operations can be reduced, and the difficulty and errors of operation urethrostenosis treatment are reduced.

Description

technical field [0001] The invention relates to a high-pressure balloon olecranon type urethral dilator. Background technique [0002] At present, the treatment of urethral strictures in urological surgery often requires balloon dilation. The urethral dilators currently used in clinical practice are cumbersome and unreasonable in design. For lower transurethral stricture, the guide wire is inserted into the bladder, guided by the guide wire, the high-pressure balloon dilator is placed into any stenotic part of the urethra for expansion, the operation is simple, and the urethral stricture can be rapidly expanded, which can reduce bleeding and injury And other complications appear, which reduces the difficulty and mistakes of surgical urethral stricture treatment. In the second stage, this dilator can be used for further second or multi-stage treatment in the treatment room of the ward according to the patient's condition. At the same time, the dilator is equipped with a urina...
