Multi-pole optical fiber microscopic endoscopic probe

Abstract

The present invention discloses a multi-pole optical fiber microscopic endoscopic probe. The multi-pole optical fiber microscopic endoscopic probe comprises an armored outer shell and three optical fiber sub-probes, and the armored outer shell internally comprises the three optical fiber sub-probes; the armored outer shell comprises a fixed clamping groove and positioning square grooves; each optical fiber sub-probe comprises a miniature microscope objective group, an armor sleeve, a wrapping outer shell, a limiter and imaging optical fiber bundles; wherein the fixed clamping groove is formedin a top end of the armored outer shell; the positioning square grooves are located in the armored outer shell; the miniature microscope objective group is arranged at a foremost end of the optical fiber sub-probe; one end of the armor sleeve is connected with the miniature microscope objective group and the other end of the armor sleeve is connected with the wrapping outer shell; and the limiteris arranged on a surface of the wrapping outer shell and in a long strip shape. A residual tumor survival situation can be observed from different perspectives, a tumor-killing effect of ablation is reflected most comprehensively, tumor residues are avoided, and recurrence risks caused by postoperative tumor residues or metastasis of patients are reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, and more specifically relates to a multi-pole fiber optic microscopic endoscopic probe. Background technique [0002] The death rate of liver cancer ranks third among malignant tumors. On average, 4 people die of liver cancer every 5 minutes in the world. The number of deaths from liver cancer in my country accounts for 55% of the world. Minimally invasive intervention represented by ablation is currently the most widely used and most promising diagnosis and treatment method. However, rapid and accurate positioning and characterization of lesions during surgery, real-time monitoring of treatment response, avoidance of residual tumors, and individualized postoperative treatment and follow-up plans are currently major clinical needs and difficulties. [0003] Currently, ablation guidance technologies mainly include CT, MRI, and US. CT positioning is accurate but there are artifacts due to motio...

AI Technical Summary

Problems solved by technology

Its monopolar probe cannot realize multi-site simultaneous detection, and cannot observe the survival of residual tumors from different perspectives, and its extension and bending performance is poor, and it cannot fully reflect the killing effect of ablation on tumors. The resolution is not high, which makes the detection efficiency Low, unable to realize online real-time monitoring of residual tumor during operation

Patients still have a high risk of recurrence due to residual tumor or metastasis after surgery
