An accurately controllable blood vessel surgical robot and an operation method thereof

Abstract

The invention relates to an accurately controllable blood vessel surgical robot and an operation method thereof, belonging to the technical field of medical devices, comprises a robot body and a control system, the robot body includes a housing and a cleaning mechanism disposed within the housing, the cleaning mechanism includes a drive system and an imaging system, the housing is formed by a cylindrical flat section and a tapered section sealed at both ends of the flat section, The taper section is a telescopic structure, the driving system comprises a bi-directional pump, a motor and a direction control device, the direction control device comprises an inlet branch pipe, an outlet branch pipe and a flow regulating valve, the telescopic structure comprises an elastic inner circumference and a waveform periphery arranged between the elastic inner circumference and the flat section, and also comprises a telescopic driving mechanism. The robot of the invention is visible, controllable, high in safety, good in stability, simple in structure, convenient in operation, low in use cost, and provides the possibility for real conversion.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to a microrobot used in intravascular precise control for surgery and its operating method. Background technique [0002] As we grow older, human blood vessels accumulate various deposits, such as plaque sticking to the blood vessel wall and thrombus accumulated in the blood vessel channel. The deposits cause blood vessel narrowing, which may reduce the level of blood passing through, and even cause blood vessel blockage. cause various diseases. Various diagnosis and treatment methods have been proposed for the prior art of vascular diseases, such as the diagnostic methods of cerebrovascular: adopt nuclear magnetic resonance machine to carry out cerebral angiography (MRA); adopt CT machine to carry out cerebral angiography (CTA); Arterial intubation is carried out, and cerebral angiography (DSA) is completed under the digital subtraction angiography machine; for exa...

AI Technical Summary

Problems solved by technology

[0005] However, the existing vascular robots basically adopt the magnetic drive method, but this method cannot perform traction drive in an accurate direction, cannot adapt to fine manipulation, and is difficult to adapt to blood vessels with complex channels

At the same time, this method requires an external magnetic field manipulator for driving operation, and the structure is complex, which increases the treatment cost and operating procedures.

In addition, this type of robot does not have a special design for the return plan, and most of them only stay in theory or concept, and cannot conduct clinical trials and truly realize the commercialization of products
