Title
(EN) OPTICAL COHERENCE TOMOGRAPHY (OCT) CATHETER FOR RESPIRATORY TRACT
Abstract
(EN)

The present invention provides an OCT catheter for the respiratory tract. An optical fiber connecting part is connected to an optical fiber, a guide wire assembly is sleeved outside the optical fiber connected to an optical fiber interface, an end of the guide wire assembly is sleeved inside the optical fiber interface connected to an optical fiber coupler, the optical fiber coupler is sleeved inside a connector sleeved inside a fixing head, an end of the fixing head is sleeved inside a sealing assembly, and the guide wire assembly sequentially passes through the connector, the fixing head and the sealing assembly. The OCT catheter is connected to the SC-type optical fiber interface through the SC-SC optical fiber coupler of a driving module. By adopting a guide wire with a small diameter, the medical OCT catheter can be applied to higher-generation bronchi, thereby expanding the application range.
