Abstract

The invention provides a separable endoscope which comprises a first component and a second component. The first component comprises an oblique mirror, the plane end of the oblique mirror is fixedly connected with one end of a rotary shaft, the other end of the rotary shaft is fixedly connected with one end of a magnet, and the magnetic is arranged in a first pipe shell. A supporting sleeve is disposed on the outer side of the rotary shaft, one end of the supporting sleeve is fixedly connected with one end of the first pipe shell, and the other end of the supporting sleeve and the oblique mirror are arranged outside the first pipe shell to form an insertion end. The second component comprises a connection optical fiber connected with one end of a second pipe shell, an insertion opening is formed in the other end of the second pipe shell, and a self-focus lens is fixedly disposed in the second pipe shell. The separable endoscope is used for solving the problems that an OCT endoscope lateral imaging probe in the prior art is complex in design and low in flexibility, is limited by the MEMS technology and only can be used for single wavelength detection.

Description

technical field [0001] The invention relates to a separate endoscope, in particular to a separate endoscope for a coherent optical tomography (OCT) system. Background technique [0002] Today, image-guided intervention technology is widely used in surgery and medical procedures. Endoscopic technology is very useful in guiding diagnosis and surgery when observing columnar organs, such as human blood vessels and digestive tract. Endoscopy techniques can be divided into two categories: non-optical endoscopy and optical endoscopy. There are two non-optical endoscopic technologies worthy of attention: endoscopic MRI and endoscopic ultrasonography. However, these two technologies have problems such as low resolution, poor signal-to-noise ratio, expensive equipment, and inconvenient use. In practical use, the efficiency is very low. Therefore, in recent years, optical imaging techniques, including traditional endoscopic techniques, fluorescence, confocal, multiphoton microscopy, ...
