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 ...

Embodiment Construction

[0027] see Figure 1 to Figure 6 , the jet-driven vascular robot of this embodiment is composed of a capsule-shaped casing, a liquid flow control device with blood as a medium, a wireless receiving control block 5, and an operating device 8 inside the casing; wherein, the capsule-shaped casing is composed of The upper half shell 1 and the lower half shell 2 are buckled together, and the working device 8 is a miniature CCD camera.

[0028] see Figure 1 to Figure 6 , The liquid flow control device consists of a variable pump 4, 12 suction nozzles 6 and 24 two-position two-way solenoid valves 7. Wherein, the suction nozzle 6 is a cylinder, and a through hole is arranged axially in the body, one end of the through hole is an entrance, and the other end shrinks inwardly to form a tiny suction nozzle; the entrance and exit of each suction nozzle 6 are parallel There are two pipelines respectively connected in series with a two-position two-way solenoid valve 7, one of which is co...
