Bending catheter with controllable head and used for interventional therapy

Abstract

The invention discloses a bending catheter with a controllable head and used for interventional therapy. A head portion of a multi-cavity catheter is connected with a main catheter soft head, the tail portion of the multi-cavity catheter is connected with an extending pipe through a connection piece, a handle is arranged outside the extending pipe, a handle sliding device is movably connected in the handle and is matched with the extending pipe, the upper end and the lower end of the sliding device are extended to the outside of the casing of the handle, a drawing wire is respectively connected with the upper side and the lower side of the sliding device, the other ends of the drawing wires penetrate through auxiliary cavities on the same side of the multi-cavity catheter and the main catheter soft head to be fixedly connected on the head portion of the main catheter soft head, and other end of the extending pipe extends to the outside of the handle to be connected with a connector. Compared with the prior art, the bending catheter has the advantages of being safe, reliable and simple in production process, is capable of meeting other performance requirements of catheters in vessels, achieves universalness of the operation process of doctors, reduces risk of patients in operation, and simultaneously achieves multipurpose performance.

Description

technical field [0001] The invention relates to an interventional catheter, in particular to an interventional catheter with controllable bending of the catheter head. Background technique [0002] Interventional medicine is a brand-new technology that has developed rapidly in recent years. As a medical device that needs to intervene in the human body, it is also a problem that must be solved in the popularization of human blood vessel injury and clinical operation. The current interventional catheters are basically shaped according to the shape of the human blood vessels or the structure of the human body. Combined with different shapes and structures, different shapes of catheters are customized to meet the needs of reaching the lesion in the circuitous blood vessels. In view of other requirements for the use of the catheter, the catheter must have a certain hardness to ensure that the doctor can rotate or pull it in the body when holding the tail to operate, so that the h...

Problems solved by technology

Even if these methods are used, the damage to the blood vessel wall cannot be avoided. Because the fully shaped polymer material or catheter has a certain degree of rigidity. During the entire delivery process, due to the expansion of the blood vessel due to the bending shaped catheter, it is easy to cause damage to the blood vessel wall. The damage or even rupture. And the whole process needs to rely on experienced doctors to do th
