High-precision automatic thrombus drilling device

Abstract

The invention discloses a high-precision automatic thrombus drilling device, which comprises a catheter and a guide wire, and further comprises a driving device, a control device and a grabbing device arranged in the catheter and used for grabbing thrombus, and the driving device is provided with a movable fixing part used for being selectively locked or loosened with at least one of the catheter, the guide wire and the grabbing device. The control device is connected with the driving device so as to control the fixing part to move and control the driving device to move; the catheter is provided with an expandable or contractible telescopic tube, and the control device is connected with the telescopic tube to control expansion or contraction of the telescopic tube; the grabbing device is provided with at least two drill bits used for winding and stretching thrombus, so that the thrombus is directly taken out of a blood vessel after the grabbing device makes contact with the thrombus. The catheter is provided with a pressure sensor, and the pressure sensor is connected with the control device so as to transmit a pressure signal to the control device; and the control device is connected with the monitoring device so that the control device can receive the monitoring data. The device is high in precision, and thrombus can be effectively grabbed.

Description

technical field [0001] The invention relates to the field of intelligent medical technology, and more specifically, relates to a high-precision automatic thrombus drilling device. Background technique [0002] In the prior art, interventional operations generally only insert a catheter from a peripheral artery, and then the doctor manually controls the transportation of the catheter, so as to deliver stents or drugs, contrast agents, etc. into the narrowed coronary artery. However, during the delivery of the catheter, due to the accumulation of friction, the complex distribution of blood vessels, and atherosclerotic plaques blocking blood vessels, it is difficult for stents or drugs, contrast agents, etc. to pass through vascular lesions. Moreover, the accuracy of manual operation is difficult to guarantee, which makes the interventional operation more risky. [0003] During the delivery process, the following situations are likely to occur: when the catheter is pushed, pul...

AI Technical Summary

Problems solved by technology

However, during the delivery of the catheter, due to the accumulation of friction, the complex distribution of blood vessels, and atherosclerotic plaques blocking blood vessels, it is difficult for stents or drugs, contrast agents, etc. to pass through the vascular lesion.

Moreover, the accuracy of manual operation is difficult to guarantee, making interventional surgery more risky

[0003] During the delivery process, the following situations are likely to occur: when the catheter is pushed, pulled, turned, etc., it is easy to cause the catheter to be bent and blocked, causing the catheter to break or cannot be pulled out; the front end of the catheter may cause damage to the blood vessel, which is likely to cause coronary artery dissociation, Occurrence of perforation, rupture, injury, etc.; catheter may be incomplete or unable to extract thrombus

In addition, due to the slow rate of thrombus dissolution, if the technique of vacuum thrombus extraction is directly adopted, it is easy to cause damage to the inner wall of the blood vessel due to excessive pressure
