Problems solved by technology

[0004] Among them, the treatment method of transurethral resection of the prostate is the gold standard for the treatment of BPH based on its own advantages, but this treatment method is invasive treatment, mainly by removing a part of the patient's prostate gland and enlarging the urethra to achieve treatment. For the purpose of this method, this method has a large trauma and requires relatively high physical fitness of the patient. For some elderly patients, it is difficult to bear the trauma caused by this method, and there is a greater risk. It is long, which further increases the pain of the recipient, and the risk of surgical treatment is high, and it is easy to bring sequelae to the patient. Statistics show that after 10% of the patients received surgical treatment, the vas deferens were damaged to varying degrees.

[0018] Such as figure 1 As shown, the present invention provides a balloon dilatation catheter for the treatment of benign prostatic hyperplasia, comprising: a body 1, a positioning capsule 2 and a support capsule 3, the positioning capsule 2 is located at the front end of the body 1, and is used to determine whether the catheter has been sent to the lesion Gland part; the supporting capsule 3 is arranged at the bottom of the positioning capsule 2 and arranged side by side with the positioning capsule 2, and the supporting capsule 3 and the positioning capsule 2 are arranged side by side. After the positioning capsule 2 reaches the bladder, it stays at the front end of the urethral opening. The support capsule 3 can span the entire prostatic gland hyperplasia, so that the support capsule 3 can achieve the purpose of expanding the prostatic gland hyperplasia. Compared with the existing surgical trauma therapy, this treatment method does not need to remove the hyperplastic pr...

[0024] On the basis of the first embodiment, the support capsule is made of PU material, which is a semi-compliant balloon. When a certain pressure is injected into the support capsule, it can expand within a certain controllable range, and can treat the diseased gland. The practical support of the body can achieve a better support effect.

[0025] In addition, this invention The positioning capsule is set to be stretched, that is, on the basis of the first embodiment, a metal guide wire is set in the expansion channel of the positioning capsule, and the positioning capsule is stretched under the action of the metal guide wire when it is poured into the human body. state, when introduced into the human body, the support rod is taken out, and the positioning capsule will retract after losing the support of the guide wire, so that the outer wall of the positioning capsule will gather and expand, and play the same positioning function as in the first embodiment.

no. 3 example

[0027] On the basis of the first embodiment, the material of the supporting bladder of the technical solution is made of aramid fiber.

[0028] According to the use situation of existing medical equipment, this technical scheme is to set reinforcement layer 31 in the sidewall of support bag 3, preferably, the material of reinforcement layer 31 is aramid fiber, and the tensile strength of this fiber is 4 times of general organic fiber. times, its modulus is 9 times that of polyester, and because of the small specific gravity of aramid fiber, its specific strength is higher than that of glass fiber, carbon fiber and boron fiber. However, its water absorption is high, which limits its application in some aspects. In the present invention, the support bag 3 comprises latex layer 32, reinforcement layer 31 and latex layer 32 successively from outside to inside, wherein the two-layer latex layer 32 inside and outside is used as the base layer because of its need to directly contact ...

Abstract

The invention relates to a balloon dilating catheter for benign prostatic hyperplasia. The balloon dilating catheter comprises a body, a positioning balloon and a support balloon. The positioning balloon is located at the front end of the body, the support balloon is arranged on the lower portion of the positioning balloon and juxtaposed with the positioning balloon, and the support balloon is used for supporting the hyperplastic prostate glands. The balloon dilating catheter has the advantages that the balloon dilating catheter can achieve the effect of treating benign prostatic hyperplasia under the condition of no trauma, dilates the hyperplastic glands through the support balloon to dredge the urethra, is convenient to use and simple to operate, can relieve pain of patients and is applicable to patients of different physical conditions.

Description

technical field [0001] The invention belongs to the field of medical appliances, in particular to a balloon dilation catheter for treating benign prostatic hyperplasia. Background technique [0002] Benign prostatic hyperplasia (BPH) is a common and progressive disease in elderly men. With the development of population aging, the incidence rate increases 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 BPH is increasing day by day, and it 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. Due to the improvement of medical level, the number of elderly patients with benign prostatic hyperplasia combined with basic diseases of heart, brain, lung, kidney and other organs is gradually increasing. For high-risk patient...
