Description

Optical fiber mechanism for medical optical tracing and medical optical tracing system

Technical Field

The invention relates to an optical fiber mechanism for medical optical tracing and a medical optical tracing system using the optical fiber mechanism.

Background

In clinical operation, because the lumen such as blood vessel, ureter, oviduct, trachea etc. is often wrapped by the tissue, the surgeon needs to be trained for a long time, and is familiar with anatomy structure, just can accurately separate the lumen such as blood vessel, ureter, oviduct, trachea etc.. Even a surgeon with a great experience may accidentally injure a vessel, a ureter, a fallopian tube, a trachea or other lumen, and therefore, a device capable of accurately identifying a vessel, a ureter, a fallopian tube, a trachea or other lumen in a tissue is required.

In addition, when lymph node cleaning is performed, the blood vessel is usually closely attached, so that the position and the range of the blood vessel also need to be marked, and the surgical operation under a endoscope is convenient.

In summary, the prior art cannot perform visible light identification on blood vessels, ureters, fallopian tubes, vas deferens, trachea and the like hidden in tissues, which is inconvenient for the identification of the endoscopic surgery. Therefore, there is a need to develop a technique and apparatus for endoscopic visual identification to facilitate endoscopic identification of vessels, ureters, fallopian tubes, vas deferens, trachea and other lumens.

The invention discloses a visible light technology-based identification technology of lumen such as blood vessels, ureters, fallopian tubes, vas deferens, trachea and the like, and discloses a special optical fiber mechanism with an integral tracing function.

Disclosure of Invention

The invention relates to an optical fiber mechanism for medical optical tracing, which is characterized in that: the optical fiber mechanism 201 for medical optical tracing contains a light guide optical fiber 22, and the light guide optical fiber 22 can realize non-single-point optical tracing of the optical fiber mechanism 201 for medical optical tracing.

The light guide fiber 22 can realize multi-point optical tracing, and through the arrangement of the luminous points, the luminous points on the light guide fiber 22 can form chain shapes and dispersion shapes, and multi-range, long-distance or integral tracing is formed for the light guide fiber 22. By combining and braiding the light guide fibers 22, a light emitting net, a light emitting ball, or the like can be formed, and space three-dimensional tracking can be performed.

The optical fiber mechanism 201 for medical optical tracing contains at least 1 light guide optical fiber 22.
