Abstract

The utility model relates to a novel technological endovascular balloon dilating catheter. The problem that an existing hard or soft balloon causes patient pain or cannot bear pressure can be effectively solved. The technical scheme for solving the problem is that the novel technological endovascular balloon dilating catheter comprises a catheter seat and a pushing rod, wherein the catheter seat is connected with the pushing rod together, the other end of the pushing rod is connected with an outer tube, an inner tube is arranged in the outer tube, one side opening is arranged on a side wall of the outer tube, the outer round face of one end of the inner tube is in sealing connection with the side opening, one end of the outer tube is connected with the balloon, the other end of the inner tube extends out of the balloon to be in sealing connection with the balloon, two ends of the inner tube are communicated with the outside, and the balloon is composed of an inner layer and an outer layer. The novel technological endovascular balloon dilating catheter is novel, unique, safe and convenient to use and flexible in control.

Description

A kind of intravascular balloon dilating catheter of novel process

Technical field

This utility model relates to technical field of medical instruments, particularly a kind of intravascular balloon dilating catheter of novel process.

Background technology

The intravascular balloon dilating catheter is mainly used in the Interventional Clinics of medical domain, under the operation of user, can convenient, fast, safe, effectively reach the narrow and obstruction that Wicresoft's ground diagnosis and treatment blood vessel causes because of tumor disease, the Stricture and occlusion of the coronary artery in expanding cardiovascular.

Development along with the medical science technology, the Interventional Clinics extend through gradually the mankind various diseases diagnosis and the treatment in, the intravascular balloon dilating catheter is exactly the method that operates diagnosis and treat according to the requirement of Interventional diagnosis and treatment, feature and noinvasive, carrying out with the skin puncture technology, sacculus dilating catheter being imported diseased region expands, blocking-up is isolated and is carried out defect measurement etc., is to solve work briefing or the difficult a kind of means that maybe can't cure of surgical operation healing.

Normally used sacculus dilating catheter is limit because of material and technique, the pressure that when selecting the sacculus of softer material for different patients' different lesions, sacculus bears is but not high, when having selected to bear the sacculus of high pressure but the blood vessel wall to the patient causes injury in various degree or brings larger pain to the patient because the material of sacculus is hard, also produced larger expense to the patient simultaneously.

Summary of the invention

For above-mentioned situation, for overcoming the defective of prior art, the purpose of this utility model just is to provide a kind of intravascular balloon dilating catheter of novel process, can solve effectively that existing sacculus is really up to the mark causes pain or sacculus to cross the soft problem that can not bear pressure to the patient.

The technical scheme of its solution is, comprise catheter block and push rod, catheter block and push rod link together, and the other end of push rod is connected with outer tube, and inner tube is housed in outer tube, a side mouth is arranged on outer tube wall, one end periphery and the side mouth of inner tube are tightly connected, and an end of outer tube is connected with sacculus, and the other end of inner tube stretches out sacculus and is sealed connected together with sacculus, the two ends of inner tube are in communication with the outside, and sacculus is made of internal layer and skin.

This utility model is novel unique, safe and convenient to use, controls flexibly.

Description of drawings

Fig. 1 is the structural representation of each parts of this utility model.

Fig. 2 is this utility model sacculus generalized section.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

Provided by Fig. 1, Fig. 2, this utility model comprises catheter block and push rod, catheter block 1 links together with push rod 2, and the other end of push rod 2 is connected with outer tube 3, and inner tube 5 is housed in outer tube 3, a side mouth is arranged on outer tube 3 sidewalls, one end periphery and the side mouth of inner tube 5 are tightly connected, and an end of outer tube 3 is connected with sacculus 4, and the other end of inner tube 5 stretches out sacculus 4 and is sealed connected together with sacculus 4, the two ends of inner tube 5 are in communication with the outside, and sacculus 4 is made of internal layer 6 and outer 7.

In order to guarantee result of use, the length of said inner tube 5 is greater than the length sum of outer tube 3 and sacculus 4.

There is developing mark to paste 8 in sacculus 4 one section of said inner tube 5.

when this utility model uses, internal layer 6 is the higher macromolecule polymeric material PA of intensity, outer 7 is the lower macromolecule polymeric material TPU of intensity, two kinds of different materials are drawn into the required material pipe of sacculus 4 by special co-extrusion technology, use again this material pipe molding sacculus 4, because this bi-material is all polyamide-based macromolecule, so intermiscibility is very good, there is not the phenomenon that the gap occurs between layers, and the characteristics of low pressure and high pressure sacculus have been had both simultaneously, the TPU material has elasticity, therefore this sacculus 4 has a plurality of nominal diameters, can satisfy simultaneously in various degree narrow of patient's diseased region, reduce the doctor and change sacculus 4 conduits because of different pathological changes in operation process, also reduced patient's expense.
