Optical coherence tomography imaging handheld probe

Abstract

The invention relates to the technical field of medical imaging devices, and provides an optical coherence tomography imaging handheld probe which comprises an optical treatment module. The optical treatment module comprises a collimating lens, an MEMS galvanometer, a focusing lens set, a right-angle reflection prism and a reflector set which are sequentially arranged along a light path, incident light from the focusing lens set is divided into two beams of reflection light rays by the right-angle reflection prism through reflection of two right-angle surfaces, the reflection light rays are reflected by the reflector set, and two beams of relative emergence light rays are outputted. According to the probe, when a pre-imaged blood vessel is observed, the blood vessel is placed between two beams of relative emergence light rays, deflection of the MEMS galvanometer is controlled and adjusted, so that the blood vessel can be scanned in two directions, a section structure of the blood vessel is observed through two sides in a bidirectional scanning process, effective depth of blood vessel imaging is greatly increased, and imaging definition is ensured.

Description

technical field [0001] The invention relates to the technical field of medical imaging equipment, in particular to an optical coherence tomography handheld probe. Background technique [0002] As a high-resolution and high-speed imaging technology, Optical Coherence Tomography (OCT) can provide three-dimensional imaging for biological tissues that cannot be achieved by other imaging technologies. OCT technology is used for vascular imaging, and has high application potential in the detection and long-term patency of blood vessels after anastomosis, thus playing an increasingly significant role in the diagnosis and treatment of vascular-related diseases. [0003] When doctors use OCT technology to image blood vessels during surgery, as vascular surgery becomes more and more refined, the requirements for doctors' medical skills are also becoming more and more stringent. However, the traditional OCT imaging equipment can only scan the pre-imaged blood vessels in a single direc...

Problems solved by technology

[0005] The purpose of the present invention is to provide a hand-held probe for optical coherence tomography, which is used to solve the problem that traditional OCT imaging equipment can only scan the pre-imaged blood vessels in a single direction, so that the imaging depth of the blood vessels is insufficient and the imaging is not clear.
