AI Technical Summary

Technical Problem

Existing prostate stents are prone to deformation due to decreased elasticity when supporting the prostate urethra for a long time, resulting in reduced support effectiveness and affecting treatment outcomes and patient comfort.

Method used

A retrievable prostate stent was designed, comprising a stent cap mechanism, a support mechanism, and an adjustment mechanism. Through the cooperation of a rotating sleeve and a fixing rope, the support force of the support wire and the bending state of the limiting wire can be adjusted to maintain the support effect and prevent dislodgement.

Benefits of technology

It effectively enhances the support of the support wire to the prostatic urethra, prevents deformation, improves treatment effectiveness and patient comfort, and can be easily retrieved, reducing inconvenience.
