Jet flow-driven blood vessel robot

Abstract

The invention discloses a jet flow-driven blood vessel robot, which consists of a capsule-shaped shell, a liquid flow control device, a wireless receiving control block (5) and an operating device (8), wherein the liquid flow control device, the wireless receiving control block (5) and the operating device (8) are arranged in the shell and use blood as a medium; the liquid flow control device consists of a variable pump (4), 12 suction and spray nozzles (6) and 24 two-position two-way electromagnetic valves (7); the inlet and outlet of each suction and spray nozzle (6) are connected with two pipes which are connected with a two-position two-way electromagnetic valve (7) in series respectively, one of the two pipes is connected with the inlet of the variable pump (4), and the other one of the two pipes is connected with the outlet of the variable pump (4); the 12 suction and spray nozzles (6) are embedded on the wall of the shell and the suction and spray openings face the outside of the shell; and the suction and spray nozzles (6) are cylinders, through holes are formed in the bodies axially, one end of each through hole is an access hole and the other end of the through hole is an inward contracted micro suction and spray nozzle. The jet flow-driven blood vessel robot of the invention is simple and convenient in control and can move flexibly.

Description

technical field [0001] The invention relates to a microrobot, in particular to a blood vessel robot. Background technique [0002] Vascular robot is a micro-robot that can enter blood vessels and move freely in blood vessels. It can complete thrombus removal, tumor resection, and drug delivery in blood vessels. It is of great significance to the prevention and treatment of cardiovascular diseases. Hotspots in the field of micro-robot research. [0003] At present, a variety of vascular robots have been developed in the world. For example, Korean researchers have developed a "vascular robot" that can move freely in blood vessels and remove blood clots. This robot is driven by an external magnetic field and rotates 20 to 30 times per second. , can move freely in thick blood vessels such as coronary arteries, large veins and large arteries, and rotate to clear blocked blood vessels. Another example is that Israeli scientists have developed a vascular robot with a diameter of ...

AI Technical Summary

Problems solved by technology

However, if this patented solution is applied to a vascular robot, there are obviously the following deficiencies: 1. Its structural form makes its shape not smooth enough, which is easy to cause damage to the blood vessel wall, and the propeller is also easy to cause damage to the blood vessel wall

2. Attitude adjustment and power generation require multiple motors, with complex structure and large power consumption
