Problems solved by technology

[0002] Cardiovascular interventional therapy is a new technique for the diagnosis and treatment of cardiovascular diseases. It does not require thoracotomy. Under the guidance of imaging methods, through the puncture of blood vessels on the surface of the body, with the help of certain instruments, the catheter is sent to the lesion site, through a specific catheter. It is a relatively advanced diagnosis and treatment method for cardiovascular diseases at present; in the prior art, the bending angle of catheter interventional devices in cardiovascular interventional operations is not easy to control, which is not conducive to the operation conduct
In addition, in the prior art, the catheter intervention is mostly performed by the doctor manually, even the doctor with the strongest ability can not completely change the direction of the catheter intervention according to the actual operation environment, let alone change its curvature; More or less, it will rub or damage the tissue of the intervening vessel wall

Abstract

The invention relates to the technical field of cardiovascular surgeries, in particular to a catheter interventional device in a cardiovascular interventional surgery. The device comprises a catheterbody and adjusting heads for driving the catheter body to move; the adjusting heads are arranged at the head end and the tail end of the catheter body, and the peripheral sides of the adjusting headsare connected with the end of the catheter body through a plurality of electric telescopic rods; the adjusting head is of an annular structure; a plurality of distance detectors are uniformly and fixedly mounted on the peripheral side of the adjusting head; and a processor is installed on the catheter body, is in wireless connection with the distance detectors, is further electrically connected with the multiple electric telescopic rods, receives data, processes and analyzes the data, adjusts the length of each electric telescopic rod and changes the angle between the adjusting head and the catheter body. By changing the angle between the adjusting head and the catheter body, the movement direction of the catheter body is changed, so that contact with tissue on the wall of the interventional catheter is avoided, friction or damage to the tissue on the wall of the interventional catheter is reduced, and the accuracy of a catheter interventional operation is improved.
