Abstract

The drug coating balloon dilatation catheter comprises a connecting tube, an outer tube is arranged on the side face of the connecting tube, an inner tube is arranged in the outer tube, a dilatation protection device is arranged on the surface of the inner tube, the dilatation protection device comprises two sets of sliding blocks, elastic rings are arranged on the inner sides of the sliding blocks, and the elastic rings are arranged on the inner sides of the sliding blocks. A blocking filter screen is arranged on the surface of the elastic ring, and a support is arranged on the inner side of the blocking filter screen. The outer pipe is arranged on the side face of the connecting pipe, the inner pipe is arranged in the outer pipe, the expansion protection device is arranged on the surface of the inner pipe, the expansion protection device comprises two sets of sliding blocks, an elastic ring is arranged between the two sets of sliding blocks, and the elastic ring is of a spring column structure and is small in two ends and large in the middle; the blocking filter screen is arranged outside the elastic ring and can block thrombus or plaque floating from the upstream during lesion treatment, and a small amount of blood is allowed to flow, so that the influence of blocking on the body is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drug-coated balloon dilatation catheter for intracranial blood vessels. Background technique [0002] Balloon dilation catheter technology is a very important technology in the field of interventional surgery, and has been widely used in various fields of urology. For the balloon dilation catheter applied to nephrostomy, it is mainly used in the steps of dilating the nephrostomy access and placing the working sheath during the operation of nephrolithiasis and upper ureteral calculi. Establishing a channel is one of the most critical and difficult steps in percutaneous nephroscopic surgery. Safe and effective channel establishment is closely related to the success rate of the operation and the incidence of postoperative complications. [0003] The existing balloon dilatation catheter lacks a certain protective function during use, and relies entirely on the balloon for ...
