Angle-adjustable cardiac ventricle catheter for cardiovascular intervention pump

Abstract

The invention discloses an angle-adjustable cardiac ventricular catheter for a cardiovascular intervention pump, which comprises a main body tube, the inlet end of the main body tube is connected with an inlet tube, the outlet end of the main body tube is connected with an outlet tube, the outlet tube is connected with an adjusting mechanism through a long connecting tube, and a plurality of developing rings are separately mounted on the main body tube along the length direction of the main body tube; wherein the main body pipe consists of an inner wall layer, an outer wall layer and a middle layer between the inner wall layer and the outer wall layer; one end of each drawing wire is fixed to the middle layer, and the other end of each drawing wire movably extends out of the middle layer, sequentially penetrates through the outlet pipe and the long connecting pipe and then is connected with an adjusting mechanism used for tensioning and releasing the drawing wires to adjust the bending angle of the main body pipe. A locking mechanism used for locking the adjusted bending angle of the main body pipe is installed on the adjusting mechanism. The device has the developing function, the bending angle is adjusted in time according to the bending degree of the blood vessel in the operation, the operation difficulty is reduced, and smooth operation is guaranteed.

Description

technical field [0001] The invention relates to a medical catheter, in particular to a ventricle catheter for cardiovascular interventional pump with adjustable angle. Background technique [0002] The twists and turns of the blood vessels in the human body often bring great difficulties to the operation. At present, the ventricular catheters used for cardiovascular interventional pumps are usually composed of inner wall layer, outer wall layer and braided layer. The structure is relatively simple, and only has a fixed The bending angle cannot be adjusted, but due to individual differences in the human body, a catheter with a single angle cannot match the vascular structure of each person. If the angle of the catheter cannot match the vascular structure of the human body, it will inevitably affect its operation. The transportation and positioning effect in the operation will greatly increase the difficulty of operation and the risk of surgical complications will be greatly i...

[0002] The twists and turns of the blood vessels in the human body often bring great difficulties to the operation. At present, the ventricular catheters used for cardiovascular interventional pumps are usually composed of inner wall layer, outer wall layer and braided layer. The structure is relatively simple, and only has a fixed The bending angle cannot be adjusted, but due to individual differences in the human body, a catheter with a single angle cannot match the vascular structure of each person. If the angle of the catheter cannot match the vascular structure of the human body, it will inevitably affect its operation The delivery and positioning effect in the middle, which greatly increases the difficulty of operation, and greatly increases the risk of surgical complications

In addition, the position of the existing ventricular catheter cannot be observed during the operation, which further increases the difficulty of the operation
