Description

Technical Field

[0001] The present invention relates to the field of thrombus dredging, and more specifically to a thrombus clearing nanorobot. Background Art

[0002] With the continuous improvement of people's living standards and the increase of social pressure, more and more people are suffering from thrombosis. Thrombosis is a substance that is very harmful to the human body. It will affect the blood circulation of the human body and cause cardiovascular diseases. If symptoms of thrombosis appear in the heart, it may cause adhesion of the valve, which may cause valvular insufficiency and bacterial endocarditis. When the thrombus does not completely block the blood vessel, it is easy to cause ischemia of the organ, and it may also form emboli, which will separate from the blood vessel wall and flow to various parts of the body with the blood, causing embolism. If the thrombosis is more serious, the blood vessels are completely blocked, and the blood cannot flow to the local organs, ischemic necrosis occurs, and it is more likely to cause bleeding or shock symptoms. Thrombosis is threatening people's health step by step. With the continuous improvement of medical level, more and more people want to get rid of the trouble of thrombosis, and the treatment of thrombosis is urgent.

[0003] The working environment of nanorobots is in an environment with a very low Reynolds coefficient. Objects can be regarded as moving in a very viscous, tiny and slow environment. Viscous force plays a dominant role and inertial force can be ignored. Under such conditions, if you want to drive the micro-nano robot, you must provide it with power continuously. However, due to its tiny size, power sources such as batteries and engines are difficult to load into micro-nano robots. Therefore, various micro-nano robot driving methods have been proposed, including self-driving (self-electrophoresis driving, self-diffusion phoresis driving, self-thermophoresis driving, bubble driving, etc.) and external field driving (magnetic field, sound field and light driving). Since the magnetic field driving method has a low magnetic field intensity and the low-frequency magnetic field can penetrate biological tissues and is harmless to organisms, it has become one of the most promising driving methods in the field of nanorobots. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a thrombus-clearing nanorobot, which has the beneficial effects of clearing thrombus and being easy to use and recover.

[0006] By adopting the above technical solution: the nanorobot is injected into the vein or artery of the human body with thrombosis through a syringe, and is developed under the irradiation of X-rays. Then the magnetic patch performs magnetic force conversion under the control of the control chip, and applies magnetic forces in different directions to the nanorobot. Because of the different magnetic pole settings of the robot body, it can rotate during the magnetic force conversion, and because of the setting of the spiral coil on the back side of the robot body, the robot body can be pushed forward during rotation to achieve movement. The magnetic pole setting of the magnetic ball connected to the robot body through the connecting rod is opposite to that of the robot body, and the volume is smaller than the robot body, and the blood obstruction it encounters is also smaller than the robot body. When the magnetism on the magnetic patch changes, the magnetic ball can swing relative to the robot body, which can break up the thrombus in the blood vessel and facilitate the removal of the thrombus.

When the magnetic field of the magnetic patch changes and drives the robot body to rotate, the spiral coil will also rotate. During the rotation, the flat structure forms an inclined plane. During the rotation, the robot body is pushed forward or backward to achieve movement. At the same time, the material structure of the connecting rod has a certain elasticity, which can provide elastic restoring force when the magnetic ball swings.

[0009] The present invention is further configured as follows: the robot body is coated with a molecular motor for driving the robot body to move; and the molecular motor is configured as ATP synthase.

[0010] By adopting the above technical solution: molecular motors such as ATP synthase can provide power after entering the blood, facilitate the movement of the robot body, and facilitate the diffusion of nanorobots in blood vessels after injection.

[0011] The present invention is further configured as follows: the diameter of the robot body is 10nm to 20nm; the diameter of the magnetic ball is 8nm to 12nm; the length of the connecting rod is 15nm to 25nm, and the diameter is 2nm to 3.5nm.

[0012] The present invention is further configured to include: a syringe for injecting nanorobots; a magnetic patch and a control chip; the control chip controls the current to flow through the coupling coil arranged in the magnetic patch, thereby generating a magnetic field for driving the robot body and the magnetic ball to move.

[0013] By adopting the above technical solution: the syringe is an existing syringe, which is used to inject the nanorobot into the blood vessel, and the role of the magnetic patch is that when the nanorobot diffuses, the control chip controls the magnetic patch to generate a magnetic field, thereby controlling the nanorobot and treating the blood clot.

[0014] The present invention is further configured as follows: two magnetic patches are provided and adhered to the front and back sides of the affected part of the human body.

Because of the different magnetic pole settings of the robot body 1, it can be rotated during the magnetic force conversion, and because of the setting of the spiral coil 2 on the rear side of the robot body 1, the robot body 1 can be pushed forward during rotation to achieve movement. The magnetic pole setting of the magnetic ball 4 connected to the robot body 1 through the connecting rod 3 is opposite to that of the robot body 1, and the volume is smaller than the robot body 1, and the blood obstruction it encounters is also smaller than the robot body 1.

[0032] In the specific implementation process, the patient first undergoes an X-ray examination to preliminarily determine the location of the thrombus, and then the nanorobot is sucked into the syringe and injected into the thrombus through the vein or artery. The control chip controls the current to pass through the coupling coil 8 inside the magnetic patch, and at the same time generates a magnetic field. The nanorobot rotates and displaces under the action of the magnetic force.
