Dilation catheter with folded bladders

Abstract

The invention discloses a dilation catheter with folded bladders. The dilation catheter comprises a main catheter body, at least one filling bladder and a liquid inlet tube which is arranged on the inner wall of the main catheter body and communicated with inner cavities of the bladders through liquid injection ports; a plurality of corrugations which are in a regular and rotatably-folded shape are formed when the interiors of the bladders are in a vacuum state, and a packing part is arranged outside the corrugations. According to the dilation catheter with the folded bladders, the bladders which are high in strength and biocompatibility and good in plasticity are made of a special material and regularly and rotatably folded through producing and processing, therefore, the bladder size is decreased to the maximum extent, and injuries to a patient are reduced to the maximum extent.

Description

technical field [0001] The invention relates to the field of medical device consumables, in particular to a biocompatible dilatation catheter for treatment of dilated prostate. Background technique [0002] Prostatic hyperplasia has become a common disease that threatens the health of elderly men. The so-called benign prostatic hyperplasia is mainly due to the hyperplasia of the prostate tissue, resulting in an increase in its volume, which in turn squeezes the surrounding organs, resulting in a smaller and narrower urinary tract, resulting in dysuria, Symptoms such as frequent nocturia, prolonged urination time, and feeling of incomplete urination, there is currently no effective preventive method for this disease. The methods for the treatment of benign prostatic hyperplasia include drug therapy, open surgical treatment and minimally invasive treatment. Medication can slow the progression of BPH, and some drugs can even reverse BPH in some patients. However, drug treatme...

AI Technical Summary

Problems solved by technology

However, drug treatment is expensive, and some patients cannot avoid surgery in the end

The effect of traditional prostatectomy or electrosurgical resection is certain, but the operation has a greater impact on patients, and the elderly's physical and psychological tolerance to surgery is poor, so many patients are unwilling to undergo surgery

Either way, expensive instruments and equipment are required, and it takes a long time to train and skilled specialists to complete

These conditions make it difficult for primary hospitals to develop, and will also cause waste of medical resources and increase the cost of medical treatment for patients

[0003] The existing prostate expansion treatment is made of latex material into a capsule, which is designed to minimize the impact on the patient's wound, but the material has poor plasticity, and the expansion in the middle is greater than that at both ends after filling. Decreased spread effect during open heal

Moreover, the material is opaque and cannot be combined with endoscopic equipment for intubation positioning, so it is difficult to guarantee the safety of the operation

[0004] In addition, because the expansion catheter needs to be directly inserted into the patient's body, the capsule forms irregular protrusions on the surface of the main body, especially during the insertion process and forms an enlarged part at the rear end, which will cause secondary trauma to the patient's wound during intervention
