Blood vessel interventional operation conduit or guide wire control device based on two-point clamping

Abstract

A blood vessel interventional operation conduit or guide wire control device based on two-point clamping comprises a main finger assembly (3), an auxiliary finger assembly (4), a drive assembly (1), and a conduit or guide wire guiding assembly (2). Rotary movement of rollers (9, 10) in the main finger assembly (3) can lead to advancing or drawing-back of a conduit or a guide wire. The main finger assembly (3) and the auxiliary finger assembly (4) can lead to forward rotation and backward rotation of the conduit or the guide wire through combined movement. When the conduit or the guide wire is installed and clamped, the auxiliary finger assembly (4) can be directly moved by a hand in a direction away from the main finger assembly (3), and after the hand releases the auxiliary finger assembly (4), the auxiliary finger assembly (4) returns under a pulling force of an inner spring (27). The drive assembly (1) can drive the main finger assembly (3) and the auxiliary finger assembly (4) to move. The conduit or guide wire guiding assembly (2) is used for achieving guiding of the conduit or the guide wire and rapid installation of a Y valve. According to the present invention, advancing and rotation of the conduit or the guide wire can be achieved, workloads and working time of a doctor are reduced, and movement precision of the conduit or the guide wire in blood vessels is improved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a catheter or guide wire manipulation device for blood vessel intervention based on two-point clamping. Background technique [0002] Vascular interventional surgery refers to that under the guidance of the digital subtraction angiography (DSA) system, the doctor manipulates the catheter (a kind of rigid flexible tube) to move in the blood vessels of the human body, treats the lesion, and achieves embolization of malformed blood vessels, Dissolving thrombus, expanding stenotic blood vessels and other purposes. [0003] At present, vascular interventional surgery is mainly done manually by doctors. The main disadvantages are: 1) Doctors work in the radiation environment, and long-term operation will cause great harm to the body; 3) Due to the complicated operation, long operation time, factors such as doctor fatigue and unstable manual operation will directly affect t...

Problems solved by technology

[0004] In response to the above problems, Germany Hansen Medical (hansen meidical) modified the catheter structure and developed an active catheter system. The problem is that the modified catheter is thicker and the scope of medical application is narrower; Beihang University has made a pusher mechanism, but It is inconvenient to install, disassemble and disinfect the catheter; the Institute of Automation of the Chinese Academy of Sciences has designed a push tube device by simulating human hands, but it cannot continuously advance the catheter, and cannot complete the simultaneous movement of propulsion and rotation
