Olecranon type urethral dilator with openable sheath

Abstract

The invention discloses an olecranon type urethral dilator with an openable sheath. The olecranon type urethral dilator comprises a dilator body, a high-pressure ball capsule and the openable sheath. The upper end of the dilator body is provided with a finger pulp groove. The lower end of the dilator body is provided with an olecranon type bend. A guide-in hole penetrating through the two ends of the dilator body is formed in the dilator body. The high-pressure ball capsule is arranged on the dilator body and located on the upper portion of the olecranon type bend. The included angle between the tangential direction of the olecranon type bend and the length direction of the dilator body is 30-45 degrees. The openable sheath is arranged outside the dilator body. The olecranon type urethral dilator is provided with the openable sheath, the dilator body can be guided by a guide wire in the guide-in hole in the dilator body when placed in, the openable sheath can be placed into the bladder under the guide of the dilator body after the urethra is sequentially dilated, and a catheter is easily guided into the bladder. Operation is easy and convenient, hemorrhage during operation, injuries and other complications can be reduced, and urethral stricture surgery treatment difficulty and errors are reduced.

Description

technical field [0001] The invention relates to an olecranon-type urethral dilator with a peelable sheath. Background technique [0002] At present, metal dilators or disposable S-shaped urethral dilators are often used in urological surgery to treat urethral strictures. Metal urethral dilators often need to be disinfected again after use. Resterilized products may lead to nosocomial infection. The guide wire access hole is not designed, which may easily lead to injury and urethral false tract during the operation. Although the disposable S-shaped urethral dilator feels in line with the design of the male urethral curvature from the design concept, it is unreasonable in clinical practice, because the male urethral anterior curvature disappears when the clinician lifts the male genitalia during the operation. It must be designed as an S-type. The material of the S-type urethral dilator is too soft, which is difficult to control during clinical operations and is likely to cau...

Problems solved by technology

[0003] Aiming at the deficiencies of the above-mentioned prior art, the problem solved by the present invention is: in the prior art, the urinary catheter is inserted into the urinary catheter through the urethra through the self-made olecranon-like hard copper wire or aluminum wire, However, this method takes a long time to introduce the catheter, which is inefficient and inconvenient to work.
