Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a urethra expansion strip with a guiding mechanism. Background Art

[0002] Urethral dilation is a common method for preventing strictures after various urethral surgeries. It can also be used for strictures that have already occurred, making the stricture more spacious and no longer obstructing urination. When performing urethral dilation, good cooperation between doctors and patients is required, and patients should not use force, which will cause local muscle contraction and make dilation difficult.

[0003] According to the Chinese patent publication number CN210992531U, the utility model relates to a urethral dilator. The urethral dilator includes an dilator body and a support body, the support body is arranged inside the dilator body, the dilator body includes a main body section and an introduction section, the introduction section is located at one end of the main body section, the main body section and the introduction section are both made of soft materials, or the introduction section is made of soft materials. When the urethral dilator is inserted into the patient's urethra, the soft dilator body located on the outer layer can avoid scratching the urethra, reduce the patient's pain, and make the urethral dilator safe. In addition, by embedding the support body inside the dilator body, the urethral dilator can make the urethral dilator have a certain hardness, thereby making the urethral dilator easier to insert into the patient's urethra.

[0004] However, the above-mentioned device is not provided with a guiding mechanism, and some existing urethral dilation strips are solid. When used, they can only enter blindly. Improper use of force may cause negative damage to the urethra, making it difficult to enter better. Utility Model Content
