Vascular endoscopy

Abstract

The invention relates to a visual mirror in a vascular cavity. The visual mirror in the vascular cavity comprises a support rod, a luminous body arranged on the support rod and a reflector used for reflecting light emitted by the luminous body and arranged on the end part of the support rod. The visual mirror in the vascular cavity can enter the vascular cavity, does not influence a visual field or have a visual field dead zone, and is simple in structure, easy to operate and low in cost.

Description

technical field [0001] The invention belongs to medical equipment, and relates to a visual mirror, in particular to a visual mirror in a blood vessel cavity. Background technique [0002] For complex patients with aortic aneurysm or aortic dissection involving the aortic arch or the entire aorta, especially those involving aortic dissection, penetrating ulcer or pseudoaneurysm in the descending aorta, if there are internal organs in the descending aorta Membrane breaks or small ulcers, etc., it is necessary to perform ascending aorta or aortic arch replacement at the same time as descending aortic stent placement (aortic "elephant trunk surgery" or modified "elephant trunk surgery"). Because for these patients whether to undergo stenting in the descending aorta, and to determine the location of the stent placement, it is first necessary to determine whether there are tears, ulcers, and intima calcification in the intima of the descending aorta. Direct observation, due to ma...

Problems solved by technology

Because for these patients whether to undergo stenting in the descending aorta and to determine the location of the stent placement, it is first necessary to determine whether there are tears, ulcers, and intima calcification in the intima of the descending aorta. Direct observation, due to many reasons such as the curvature of the vascular cavity, the influence of blood in the vascular cavity, the direct light of the surgical shadowless light source, and the limited direct viewing angle of the naked eye, errors often occur in judging whether the intima is intact or associated with lesions during surgery. Differences in the selection of surgical methods, such as missed diagnosis of endometrial lesions, will cause fundamental differences in postoperative outcomes of patients. Some patients will have to undergo surgery again due to errors in the determination of endometrial conditions during surgery, which will increase the pain and economic burden of patients , seriously affecting the curative effect of surgery and long-term treatment
