A base for installing an endoscopic imaging optical probe

Abstract

A base used for installing an endoscopic imaging optical probe comprises a micro motor containing table, an outer sleeve containing table and an optical fiber containing table which are sequentially arranged and two connection rods; a micro motor groove is formed in the upper surface of the micro motor containing table and used for a micro motor to be placed, and two through motor round holes are formed in the lower portion of the micro motor containing table and used for the connection rods to be inserted therein; the outer sleeve containing table comprises an upper table face and an outer sleeve containing table base which are connected through screws and a spring, an outer sleeve groove is formed in the upper surface of the upper table face and used for an outer sleeve to be placed, and two through outer sleeve round holes are formed in the lower portion of the outer sleeve containing table base and used for the connection rods to be inserted therein; an optical fiber groove is formed in the upper surface of the optical fiber containing table and used for optical fibers to be placed, and two through optical fiber round holes are formed in the lower portion of the optical fiber containing table and used for the connection rods to be inserted therein. The problems that when the micro motor, the outer sleeve and the optical fibers are installed through manual alignment, large errors are caused, and even installation fails are solved.

Description

technical field [0001] The invention relates to the technical field of endoscopic imaging optical probes, in particular to a base for installing endoscopic imaging optical probes. Background technique [0002] Optical coherence tomography (Optical Coherence Tomography, OCT) is an advanced imaging technology using the principle of weak coherent optical interferometer, which is widely used in the medical field. This technology puts forward strict requirements on the optical probe when performing endoscopic biomedical detection. One of the main requirements is that the size of the probe should be as small as possible to facilitate entry into micro-cavities such as blood vessels. In 2004, the Zhongping Chen research group of the University of California, Irvine proposed in the document "In vivoendoscopic optical coherence tomography by use of arotationalmicroelectromechanical system probe" that the OCT endoscopic imaging optical probe uses a micro motor to replace the torque lin...

AI Technical Summary

Problems solved by technology

However, there are currently no good auxiliary tools for the assembly of OCT optical probes based on micro-motors. Manual alignment to install micro-motors, outer sleeves, and optical fibers will cause large errors, and a slight jitter will cause micro-motors or optical fiber ends. damage to the self-focusing lens or optical fiber, so a base that can assist in installation is required
