stents for benign prostatic hyperplasia

Abstract

The invention provides a support for treating benign prostatic hyperplasia. The process of implanting the support does not need a rigid condition, cooling and heating are not needed, the requirement in material quality is low, and the process is easy to control. The rigid condition is not needed in the process of implanting the support, the process can be conducted at a normal temperature, an arc-shaped supporting piece does not need to be strictly controlled, the process is easy to control, a cylindrical objected is formed after implanting the support, the cylinder object is hollow inside and does not stop proceeding of micturition, a strutting mechanism achieves that a strutting state can be firmly maintained through a cam self-locking mechanism, the positioning problem of a pull rod piece and a push-pull rod is solved through the effect of a magnetic field and the accurate position is guaranteed, through the adoption of a pull ring which is led in one way, the push-pull rod is allowed to go in and not allowed to go out, thus normal retraction of the push-pull rod is guaranteed, the supports for benign prostatic hyperplasia can be produced into different sizes according to actual requirements, and thus the support for treating benign prostatic hyperplasia has high practicability.

Description

technical field [0001] The invention relates to the technical field of the prostate, in particular to a bracket for treating hyperplasia of the prostate. Background technique [0002] Prostatic hyperplasia is one of the common diseases of elderly men. It is a progressive disease. With the aging of the population, the incidence rate is increasing year by year. According to relevant statistics in China, the incidence rate of males in their 50s is more than 50%, and it can reach 90% when they are 80 years old. The incidence of benign prostatic hyperplasia is increasing and has become the most common disease in urology. Due to the high incidence and serious impact on the quality of life, treatment has always been one of the focuses of clinical research. [0003] The existing method for treating the prostate is to use memory alloy stents. When in use, the stents are placed on the catheter with the front end of the measurement and control at low temperature, and ice saline is pou...

Problems solved by technology

[0006] The invention does not require strict conditions during the implantation process, it can be carried out at room temperature, the arc-shaped support piece does not need strict control, the process is easy to control, and a cylindrical object is formed after being placed in, the interior is hollow, and does not block urination The stretching mechanism is realized by the cam self-locking mechanism, and the stretching is kept firm. The magnetic field is used to achieve the positioning of the pull rod and the push-pull rod. It is not easy to rotate as a whole after insertion. The present invention uses the effect of the magnetic field to make the partial rotation of the front catheter to achieve the positioning problem of the pull rod and the push-pull rod. The positioning is accurate and solves the problem that the catheter cannot be rotated and the positioning of the pull rod and the push-pull rod is difficult. The problem is that the pull ring with one-way introduction makes the push-pull rod in and out, ensuring the normal retraction of the push-pull rod. The pull ring is connected with a display light, so that the opening and closing of the pull ring can be clearly displayed outside the body. It is helpful for the doctor to prepare the state of the pull ring and determine whether the pull ring is set on the push-pull rod. The work is reliable. Using the pneumatic telescopic rod, the stretching process is gentle, and there is no need for complicated structures inside; different models can be made according to actual needs. Prostate stent, strong adaptability
