Vascular endoscope

Abstract

The invention relates to a vascular endoscope capable of preventing doctors from being radiated by an angiography instrument. The vascular endoscope comprises illumination optical fibers, a flexible outer sleeve, an optical fiber sleeve, a single-mode optical fiber, a self-focusing lens and a transparent end cover, wherein the periphery of the single-mode optical fiber is sleeved with the opticalfiber sleeve; the illumination optical fibers are distributed on the periphery of the optical fiber sleeve in the circumferential direction and used for providing end illumination; the illumination optical fibers are uniformly distributed and arranged around the single-mode optical fiber; the periphery of the optical fiber sleeve is sleeved with the flexible outer sleeve; the illumination opticalfibers are embedded into the flexible outer sleeve; the transparent end cover is packaged at one ends of the illumination optical fibers and the flexible outer sleeve; and the self-focusing lens is installed between the transparent end cover and the optical fiber sleeve. Compared with the prior art, the vascular endoscope has the advantages that an interventional doctor can clearly know the specific position of a catheter or a guide wire in the blood vessel without the help of the angiography instrument, so that the doctor can be prevented from being injured by X-ray cumulative radiation dosecaused by the angiography instrument, and the occupational life of the interventional doctor is prolonged.

Description

[technical field] [0001] The invention relates to the technical field of medical instruments, in particular to a blood vessel endoscope which can protect doctors from the radiation of an angiography apparatus. [Background technique] [0002] At present, the existing vascular interventional surgery is basically that the doctor manually sends the guide wire into the patient's blood vessel, that is, the doctor manually controls the forward and backward displacement, rotation and turning of the guide wire in the patient's blood vessel under the guidance of the real-time imaging of the angiography instrument. wait for action. Because the doctor is too close to the angiography machine, although the doctor will have the protection of lead clothing, the accumulation of long-term manual operation will still lead to the continuous accumulation of radiation dose of X-ray scattered rays. This accumulation of radiation dose is the biggest threat to the health of vascular interventional d...

Because the doctor is too close to the angiography machine, although the doctor will have the protection of lead clothing, the accumulation of long-term manual operation will still lead to the continuous accumulation of radiation dose of X-ray scattered rays. This accumulation of radiation dose is the biggest threat to the health of vascular interventional doctors
