External-driven breaststroke robot used for vascular intervention

Abstract

The invention provides an external-driven breaststroke robot used for vascular intervention. The external-driven breaststroke robot mainly comprises an elastic hinge (1), an upper permanent magnet (2), a lower permanent magnet (3), a lower pin (4), an upper pin (5), a lower tail fin (6) and an upper tail fin (7). Two ends of the elastic hinge (1) are connected with the upper permanent magnet (2) and the lower permanent magnet (3) in an adhesive mode, the magnetic polarity of the upper permanent magnet (2) is opposite to the magnetic polarity of the lower permanent magnet (3), the lower pin (4) and the upper pin (5) are inserted into holes of the lower permanent magnet (3) and the upper permanent magnet (2) respectively, and the lower pin (4) and the upper pin (5) are connected with the lower tail fin (6) and the upper tail fin (7) respectively. The micro breaststroke robot can be driven and controlled externally to achieve vascular intervention, and the external-driven breaststroke robot has the advantages of being simple in structure, prone to miniaturization and high in reliability.

Description

technical field [0001] The invention relates to a robot, in particular to a robot capable of using an external field drive to realize breaststroke in a blood vessel environment. Background technique [0002] Cardiovascular and cerebrovascular diseases caused by living habits are taking people's lives more and more rapidly. Removing the thrombus accumulated in the blood vessels, although it cannot eliminate the disease in essence, can save lives, so it has very important clinical significance. [0003] In terms of clinical vascular intervention technology, the current main concern is the use of electromechanical control technology to effectively, reliably and safely operate the remote operation of catheters, guide wires and vascular stents during vascular interventional treatment, and use robot-assisted technology to replace doctors in the radiation environment. work, but few technologies involve micro-robots that actively enter blood vessels to achieve autonomous movement an...

Problems solved by technology

[0004] Most of the existing driving methods are based on traditional methods, for example, the patent CN03232608.4 discloses a micro-robot driven by a micro-motor, and the micro-robot disclosed in the patent CN99113465.6 uses a reverse spiral to generate propulsion. Patent CN201010299445.6 discloses a jet-driven vascular robot, and CN201110103184.0 discloses a micro-robot for blood vessel intervention driven by an external field. This type of robot has a complex structure and is difficult to miniaturize in size

Small size, simple structure, controllable motion, and high reliability are the basic requirements for micro-robots for vascular intervention. It is difficult for the current technical design to meet these requirements at the same time.
