[Study on the Application of Optical Fiber Light Transmission Method in the Removal of Soft Tissue Foreign Bodies].

To address the current challenges of difficult removal and potential residuals of soft tissue foreign bodies, this paper utilizes the principle of different light reflection degrees between foreign bodies and tissues to construct a foreign body localization device based on modified PMMA optical fibers. An optical fiber light transmission method is designed for the localization of soft tissue foreign bodies. To verify the practicality and reliability of the device, tests and comparisons are conducted on biological tissue models. The results show that the device can locate foreign bodies more efficiently and at lower cost, facilitating the complete removal of soft tissue foreign bodies.
