Guide wire and catheter operating device for interventional embolization

Abstract

The utility model discloses a guide wire and catheter operating device for interventional embolization and relates to a medical instrument. The device comprises a guide wire and catheter propelling module, a guide wire and catheter rotating module, a telescopic catheter mechanism, a movable radiography catheter locking mechanism, a guide wire force feedback module and a control system, wherein theguide wire and catheter propelling module comprises a guide wire feeding end micro precision lead screw module and a catheter feeding end micro precision lead screw module, and is further provided with a pressing moving sliding block; the guide wire and catheter rotating module is composed of a hollow rotating index plate and a guide wire and catheter locking device; the telescopic catheter mechanism comprises three groups of telescopic catheters; the guide wire force feedback module comprises a film pressure sensor and a pressure acquisition card; the movable radiography catheter locking mechanism is arranged at the front section of the catheter feeding end micro precision lead screw module; and the control system is used for controlling the propelling module and the rotating module to work coordinately. The device is simple in structure and convenient to operate, can realize independent motion control on a guide wire and a catheter, has a real-time force feedback function, is convenient in accessory replacement and can improve the operation efficiency.

Description

technical field [0001] The invention relates to a medical device, in particular to a guide wire catheter manipulation device for interventional embolization surgery. Background technique [0002] Embolization refers to the controlled injection of plugs into the supply vessels of diseased organs through surgical intervention in arteries or veins to occlude them, thereby interrupting the back-end blood supply, in order to achieve control of bleeding, treatment of tumors and vascular lesions And the purpose of eliminating the function of diseased organs. [0003] Interventional embolization surgery usually requires surgeons to construct tiny wounds on the surface of the human body with puncture needles, catheters, and guide wires under the guidance and monitoring of digital angiography machines, magnetic resonance, and X-ray imaging equipment. The catheter builds a basic channel, and then inserts the guide wire into the catheter and ensures that the guide wire extends out of t...

Problems solved by technology

However, the mechanical structure involved in the feeding and rotation control of the guide wire catheter is relatively complicated. The motor adopts a gear transmission mechanism, and the equipment vibrates greatly under low-speed control and motor start-stop conditions. At the same time, it is considered that blood will overflow and easily contaminate the equipment during the operation. Not easy to clean
