Optical rotary junction module for oct system

Abstract

An optical rotary junction module for an OCT system according to the present invention includes an OCT connection part having a screw thread formed on an outer peripheral surface thereof, the OCT connection part being connected to an OCT system configured to produce light, a connecting/fixing part having a screw thread formed on an inner peripheral surface thereof and screw-coupled to and engaging with the screw thread formed on the outer peripheral surface of the OCT connection part, a first housing having a screw thread formed on an inner peripheral surface of one end thereof and a screw thread formed on an inner peripheral surface of the other end thereof, the first housing having one end screw-coupled to the connecting/fixing part, a second housing screw-coupled to the screw thread formed on the inner peripheral surface of the other end of the first housing, a hollow motor inserted into the second housing and configured to generate rotational power, and an adapter configured to be coupled to an imaging catheter configured to be inserted into a blood vessel of a human body and transmit light received from the OCT system. The optical rotary junction module has the effects of reducing noise generated during high-speed rotation, and preventing failure caused by abrasion or the like. Moreover, the module may be structurally simplified and reduced in size, and the product cost per unit thereof may be lowered by minimizing the components.
