Catheter or guide wire operating device for vessel interventional operation

Abstract

The invention discloses a catheter or guide wire operating device for a vessel interventional operation. The catheter or guide wire operating device for the vessel interventional operation comprises a main directing assembly, an auxiliary directing assembly, a drive assembly and a catheter guide assembly or a guide wire guide assembly. A rolling wheel of the main directing assembly rotates to ensure that the catheter or the guide wire moves forwards or backwards. By moving in a combined mode, the main directing assembly and the auxiliary ensure that the catheter or the guide wire rotates in a positive direction and rotates in a reverse direction. When the catheter or the guide wire is assembled, the auxiliary directing assembly can directly move along the direction away from the main directing assembly by a hand; and when the hand is loosened, the auxiliary directing assembly returns through the impacts of inner spring tension. The drive assembly is a motion drive for achieving motion of the main directing assembly and the auxiliary directing assembly. The catheter guide assembly or the guide wire guide assembly is used for achieving fast arrangement of the catheter of the guide wire guide and a Y valve. The catheter or guide wire operating device for the vessel interventional operation can ensure that the catheter or the guide wire moves forwards or rotates, reduces work load of a doctor, reduces working hours of the doctor under a radiation environment, and improves motion precision of the catheter or the guide wire in a vessel.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a catheter or guide wire manipulation device for vascular interventional operations. 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 the quality of operation, and th...

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 assemble, disassemble and disinfect the catheter; the Institute of Automation of the Chinese Academy of Sciences has designed a device for pushing the catheter by simulating human hands, but it cannot continuously push the catheter, and cannot complete the simultaneous movement of propulsion and rotation. This patent will overcome the above problems and propose a new type of catheter manipulation device
