Medical stent type supporting balloon and water injection type covered stent

Abstract

The invention discloses a medical stent type supporting balloon and a covered stent. The medical stent type supporting balloon comprises a flexible cavity body and a closed pipeline, wherein an operating passage is arranged in the cavity body; the closed pipeline is arranged on the cavity body, the closed pipeline at least respectively extends for a distance on the cavity body along the circumferential direction and the axial direction of the operating passage and at least comprises a gas or liquid injecting opening, and after gas or liquid is injected into the closed pipeline via the injecting opening, expansionary force is generated in the circumferential direction and the axial direction of the operating passage of the cavity body, so the cavity body opens to form the operating passage. The invention can form effective support in the operating passage in the human body established for an operation, and simultaneously effectively avoids the damage on internal tissues and avoids the occurrence of discomfort. The invention also can be used as a water injection type covered stent, provides support in tumor neck remodeling operation in a blood vessel stenosis molding operation or a broad carotid aneurysm embolization operation and keeps the unobstructed flow of parent artery blood.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical bracket type support balloon and a water injection type membrane bracket. Background technique [0002] At present, medical technology is developing rapidly, and various advanced medical technologies can be used to treat patients' diseases. Among them, the use of surgical treatment can quickly and effectively treat the lesions in the patient's body, and the corresponding medical equipment is generally required to provide equipment support for the operation during the operation. [0003] When operating on a lesion in the human body, it is generally necessary to first establish an operation channel from the outside to the lesion in the body, so that instruments can be inserted into the channel to operate on the lesion. The channel can be established using special medical equipment, such as some surgical brain endoscopes, nasal endoscopes, hysteroscopes and the like. The brain endosco...

Problems solved by technology

[0009] In addition, the consumables required for the dilation balloon and metal stent implantation of the above-mentioned prior art are almost entirely dependent on imports, which are expensive and far beyond the acceptable cost of ordinary patients in our country.
