Puncture biopsy needle with optical fiber probes

Abstract

The invention relates to the field of medical equipment and oncology, and relates to a puncture biopsy needle with optical fiber probes. The puncture biopsy needle with optical fiber probes mainly comprises a host machine, a puncture needle, optical fiber probes and a display device, wherein the optical fiber probes are arranged on the outer edge of a needle core of the puncture biopsy needle. According to the puncture biopsy needle, the optical fiber probes are adopted to transmit lasers to the tip of the puncture biopsy needle, and therefore the real-time acquisition of Raman spectrum signals of pinpoint contact tissues or cells is achieved, and the signals are automatically analyzed and monitored. When the puncture biopsy needle is used, the Raman spectrum of the pinpoint tissues and cells can be monitored in real time in punctures, and by acquiring information of cancerous status and the like of the current needle tip contact tissues and cells through analyzing spectrum signals, tumors can be identified from normal tissues in real time in punctures, which helps doctors to find out cancerous tissues through biopsy more precisely, therefore the positive rate of biopsy is increased, complications caused by vascular injury and other normal tissue injuries are avoided, and the safety of punctures is improved.

Description

technical field [0001] The invention relates to the fields of medical equipment and oncology. The invention relates to a novel medical puncture biopsy needle, in particular to a puncture biopsy needle with an optical fiber probe. On the basis of the original puncture biopsy needle, the present invention adds the design of Raman optical fiber probe, which can intelligently identify tumor tissue and normal tissue by detecting the difference of Raman spectrum in real time; further, it can be used for rapid diagnosis of benign and malignant tumors. Background technique [0002] The prior art discloses that tumor pathological diagnosis is a prerequisite for tumor treatment. Needle biopsy is the main way to obtain histopathological specimens. Generally, although needle biopsy is fast, easy, accurate, safe, and economical, due to the heterogeneity of the location and structure of the lesion, the accuracy of needle biopsy and the safety of needle biopsy are affected clinically.

Problems solved by technology

Generally, although needle biopsy is fast, easy, accurate, safe, and economical, due to the heterogeneity of the location and structure of the lesion, the accuracy of needle biopsy and the safety of needle biopsy are affected clinically. Clinical treatment poses a big problem

Clinical practice shows that the current various biopsy needles cannot identify tumor tissue and normal tissue in real time. Only relying on the experience of doctors, it is difficult to accurately distinguish the boundary between tumor tissue and normal tissue. This restricts the accuracy of biopsy and often requires multiple biopsy to confirm the diagnosis
