Problems solved by technology

Thrombectomy is a relatively thorough thrombectomy, but the damage to the vessel wall is too great, which can easily cause various concurrent inflammations
The operation of laser thrombectomy is difficult. If the laser energy is too low, it will be ineffective, and if the energy is too high, it will damage the blood vessels, and it is also easy to cause various complications.
The thrombectomy with the catcher is easy to operate and causes little damage to the vessel wall, but it often fails to catch the blood clot
Thrombectomy with thrombus-catching net is easy to operate, but it cannot be used in intracranial blood vessels due to its large volume
In summary, the existing mechanical thrombectomy methods fail to effectively capture thrombus falling off or spilling out of the thrombectomy stent, which may easily lead to vascular re-embolization and complications caused by thrombectomy.

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] It should be noted that, in the field of interventional medicine, the end of the instrument relatively close to the operator is generally called the proximal end, and the end of the instrument relatively far from the operator is called the distal end. Specifically, the distal end refers to the end of the instrument that can be freely inserted into the animal or human body. The near end refers to the end for user or machine operation or the...

Abstract

The invention discloses a thrombectomy device and a thrombectomy system. The thrombectomy device comprises a thrombectomy stent and a protective umbrella arranged at the far end of the thrombectomy stent, wherein the protective umbrella comprises a main body structure and a connecting structure which are adjacent to each other; the main body structure is formed by weaving umbrella ribs in a staggered manner; at least two connecting ribs are connected to the near end of the main body structure in a dispersed manner; and the connecting structure is formed by encircling the at least two connecting ribs. According to the thrombectomy device and the thrombectomy system, the problem of re-embolism of blood vessels caused by falling off from the thrombectomy stent or overflowing of thrombus is solved, and complications caused by thrombectomy treatment are prevented, so that the re-circulation rate of the blood vessels is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thrombus retrieval device and a thrombus retrieval system. Background technique [0002] A thrombus is a small piece of blood that forms on the surface of a vessel in the cardiovascular system where the lining has been peeled off or repaired. Thrombosis spreads throughout the entire cardiovascular system, affecting tissues and organs throughout the body, not limited to myocardial infarction, deep vein thrombosis, or cerebrovascular thrombosis. Thrombosis can occur in blood vessels anywhere in the body. Intracranial thrombosis is a special clinical type of cerebrovascular disease. It is easy to cause cerebral embolism and has the characteristics of high morbidity, disability, mortality and recurrence. It is the cause of death and disability in middle-aged and elderly people. major diseases. [0003] Vascular recanalization is the key to the treatment of acute ischemic ...
