Description

Prevent urethra support of displacement Technical Field The utility model relates to the technical field of urethral stents, in particular to an anti-displacement urethral stent. Background The urethra is a conduit leading from the bladder to the outside of the body and is mainly responsible for urination, and the urethral stent is a medical device for treating urethral stricture or obstruction. It is usually made of stainless steel, synthetic fiber silica gel or nickel titanium alloy, and can be placed on the narrow part of urethra through cystoscope to spread the narrow or blocked part and expand the urethra which is closed by the original narrow part, so as to help the patient recover the normal urination function. According to bulletin number CN215739691U an anti-drop's plain type urethra support, this patent includes urethra support body, and a plurality of horizontal through-holes that set up have been seted up in the outside of urethra support body, and a plurality of through-holes are equidistant setting, and the outside fixed cover of urethra support body is equipped with a plurality of anti-skidding circles, fixedly connected with a plurality of holding ring on the inner wall of urethra support body. The utility model has reasonable structural design, good support and stability, no deviation in human body, expected treatment effect before operation, easy taking out after operation, good use effect and high working efficiency. However, the two ends of the urethral stent are completely circular, however, the urethra is a relatively narrow pipeline with a certain curvature, if the two ends of the stent are completely circular, certain resistance can be generated when urine is discharged, especially at the position where the urethra is bent or narrow, the resistance can lead to unsmooth urine discharge, the insertion end of the urethral stent is circular, the smooth insertion of the urethral stent is not facilitated, and the damage to urethral tissues is larger during the insertion, so that the use of the urethral stent is affected. Disclosure of utility model The utility model aims to provide an anti-displacement urethral stent so as to solve the problems in the prior art.
