Abstract

The invention discloses an optical coherence tomography probe. The optical coherence tomography probe comprises a tubular cover body, at least one electrode, an optical fiber scanner and an auxiliary positioning element, the electrode is arranged on the outer surface of the tubular cover body. The optical fiber scanner is arranged in the tubular cover body, and the optical fiber scanner comprises an optical fiber and an optical lens. The optical lens is arranged at the light-emitting end of the optical fiber, and the position of the optical lens corresponds to the light-transmitting part of the tubular cover body. The auxiliary positioning element is arranged on the tubular cover body, and the auxiliary positioning element is overlapped with a part of the light-transmitting part. A light beam emitted by the optical fiber scanner travels through the light-permeable part to generate a tomography image, and a part of the light beam interacts with the auxiliary positioning element to form a feature point corresponding to the auxiliary positioning element in the tomography image.

Description

technical field [0001] The invention relates to an optical coherence tomography probe. Background technique [0002] With the development of medical technology, the treatment of Parkinson's disease has changed from taking levodopamine drugs in the early stage of the disease, and in the middle and late stages, surgical operations can also be used to regulate the operation of brain circuits to make up for the limitations and side effects of drug treatment. Deep Brain Stimulation (DBS) is currently the main surgical treatment for Parkinson's disease. The principle of deep brain stimulation is to implant slender electrodes into the subthalamic nucleus (STN) or globus pallidus internal (Globus pallidus internal) in the deep brain, and correct the abnormality of the nerve conduction circuit by electrical stimulation. , and achieve the control of movement disorder symptoms and the improvement of the patient's motor function. [0003] The deep brain stimulation procedure can be di...
