Brachial artery approach abdominal aorta blood flow protection device

Abstract

The invention relates to a brachial artery approach abdominal aorta blood flow protection device, and belongs to the technical field of medical instruments. Comprising a protective umbrella device arranged at one end far away from an operator, a plastic pipe used for recovering or releasing the protective umbrella device and an operating handle close to one end of the operator, the operating grip is movably connected with one end of the plastic pipe, and an operating pull rod for moving the plastic pipe is arranged on the plastic pipe; a stay wire for tightening and shrinking the protective umbrella is arranged in the protective umbrella device; a stay wire tube and a guide sheath are arranged in the plastic tube in a penetrating manner; and the stay wire penetrates through the stay wire pipe and is connected with a stay wire pull valve arranged on the operating grip. The device can be suitable for blood flow protection of an interventional therapy operation at the near end of the aorta abdominalis; the thrombectomy device can be used for solving the problem that the renal artery and the lower limb artery are embolized due to falling of scraps caused by thrombectomy operation, and preventing adverse events such as renal insufficiency and'garbage feet '.

Description

technical field [0001] The invention relates to a brachial artery access abdominal aorta blood flow protection device, which belongs to the technical field of medical devices. Background technique [0002] Superior mesenteric artery embolism or thrombosis is a relatively common clinical emergency. However, the current thrombectomy in vascular surgery is prone to produce thrombus debris and transport it through the abdominal aorta to embolize the renal arteries and distal lower extremity arterioles. Carotid arteries supply brain tissue. Considering serious adverse events such as stroke caused by debris shedding when carotid artery stenting is performed on patients with carotid artery stenosis, there are relatively mature cerebral blood flow protection devices in clinical practice. The body tissues supplied by the small arteries of the lower extremities are the toes and other parts, which will not cause serious disability and fatal consequences and have not been paid enough a...

AI Technical Summary

Problems solved by technology

Although the thrombectomy operation may embolize the renal artery and cause serious adverse consequences, due to the fast blood flow and high pressure in the abdominal aorta, there is no corresponding remote blood flow protection device in clinical practice.
