Thrombus removing device capable of preventing damage on inner wall of blood vessel

Abstract

The invention discloses a thrombus removing device capable of preventing damage on an inner wall of a blood vessel. The thrombus removing device of the invention comprises an outer support sleeving device and an internal removing device; the outer support sleeving device comprises a metal sleeve and an outer sleeving tube; an infrared detection device is arranged on an end surface of the metal sleeve which faces a cutting device; the internal cleaning device comprises a first thrombus channel, a second thrombus channel and the cutting device; the cutting device comprises blade support strips, blades, a pin roll, an air cylinder, a rubber sleeve and projected strips; an internal removing device of the thrombus removing device supports one side of the inner wall of the blood vessel with the thrombus through the outer support sleeving device before working to prevent the inner wall of the blood vessel from being scratched during a removing process; a motor drives the second thrombus channel to rotate and the blade support stripes expand through the air cylinder; and infrared detection device on the outer support sleeving device can detect an opening position of the blades. The thrombus removing device capable of preventing damage on inner wall of blood vessel can provide convenience to medical staff to control the blades not to go beyond a scratching-proof fillet and guarantees that the inner wall of the blood vessel is not damaged while the vessel is unblocked.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a thrombus remover capable of preventing damage to the inner wall of blood vessels. Background technique [0002] Cardiovascular disease has a high incidence rate in the world and has become the number one killer of health. At present, many hospitals have begun to use suction to remove the newly established thrombus, a new technology to expel the thrombus from the body. There are two types of suction devices: one is manual and the other is mechanical. At present, most domestic hospitals use manual methods when rescuing acute myocardial infarction, which is simple, quick and easy to control. The biggest advantage is that combined with the suction method, the thrombus is rarely poked far away. [0003] A thrombus removal device proposed by Taiwan Chang Gung Yumei Hospital. The probe of this device passes through the thrombus, and releases a metal capsule at the other end of the pr...

AI Technical Summary

Problems solved by technology

[0004] 1. After the thrombus is formed, the opposite side of the thrombus cannot be observed because the contrast medium cannot pass through. If the probe is used directly to penetrate, because the blood vessel is not straight, the length of the thrombus itself cannot be judged, which may cause the blood vessel to rupture. Threat to the life of the patient;

[0005] 2. During the pushing process of the probe, it is easy to cause unbalanced force on both ends of the thrombus, so that the thrombus is pushed to other places in the blood vessel, which affects the progress of the removal operation;

[0006] 3. When the metal capsule is expanded, it is easy to scratch the inner wall of the blood vessel due to the inconvenience of seeing the internal condition of the blood vessel;

[0007] 4. After the thrombus is removed, it is not convenient to discharge it out of the body;

[0008] 5. The existing thrombus remover directly pulls the thrombus out of the blood vessel, but because the thrombus grows and connects with the inner wall of the blood vessel, this process can easily damage the inner wall of the blood vessel, which in turn endangers the life of the patient
