Novel angiographic catheter

Abstract

The invention relates to the technical field of interventional diagnosis and treatment auxiliary physical therapy instruments, in particular to a novel angiographic catheter, a reinforcing tube, a pipeline and a tube seat of the novel angiographic catheter are of independent general structures, the requirement for production injection molding is low, the assembly process is simple and convenient, the overall production efficiency is high, the production cost is low, and meanwhile in the implantation operation process, the production cost is low. A medical worker can grasp the catheter conveniently, practicability is good, the catheter comprises a tube base, a reinforcing tube, a pipeline and two butterfly wings, the two butterfly wings are fixedly connected with the tube base, a first straight section, a second conical section, a third straight section and a fourth conical section are arranged in the tube base, the first straight section, the second conical section, the third straight section and the fourth conical section are communicated in sequence, and the first straight section, the second conical section, the third straight section and the fourth conical section are communicated in sequence. The pipeline is embedded in the reinforcing pipe, and the pipeline and the reinforcing pipe are both embedded in the pipe seat.

Description

Technical field [0001] The present invention relates to an interventional diagnosis and treatment of auxiliary turapeutic instrument technology, and is specifically a new type of angiography conduit. Background technique [0002] It is well known that contrast is a substance containing high atomic elements in radiology, and then takes an auxiliary inspection method for medical diagnosis in the predictoric body to facilitate medical diagnosis. The catheter, the contrast conduit is a long hose, which mainly acts to enable the contrast agent to introduce the blood vessels, produce a contrast effect, and therefore, a sample catheter should have the following basic conditions: the inner tube is smooth to produce high flow, developing performance High, maintaining the prototype, can be easily deformed and can have a guide wire, easy to pass all kinds of characteristics. [0003] At present, the shadow catheter in the market is generally connected by the tube, the reinforcing tube and t...

AI Technical Summary

Problems solved by technology

[0003] At present, the contrast catheters on the market are generally composed of tube bases, reinforcing tubes and pipelines connected in sequence. There are roughly two methods: one is to insert the pipe into the pipe seat for bonding connection, and then put the reinforcing tube on the pipe seat for bonding connection; the other is to insert the pipe and the reinforcing pipe into the pipe seat at the same time Injection molding connection of embedded parts, the assembly work in the production process of the above-mentioned first method is more cumbersome, and the production process of the injection molding process of the second method is more complicated, so the overall production process of the above two methods is cumbersome, which is easy to cause low production efficiency , the production cost is high, and at the same time, the hands of the medical staff are not easy to grasp during the implantation operation, which will easily cause the medical staff to be tired and the practicability is poor
