Operation navigation system based on near infrared imaging

Abstract

The invention discloses an operation navigation system based on near infrared imaging. The operation navigation system comprises an near infrared image probe, an endoscopy probe, an imaging work station and a virtual reality display device, wherein the near infrared image probe is used for targeting pathological change tissues to be cut through operation, and can generate near infrared fluorescence signals under the irradiation of exciting light; the endoscopy probe comprises an exciting light source and a near infrared fluorescence collector; the exciting light source is used for generating the exciting light; the near infrared fluorescence collector is used for collecting the near infrared fluorescence signals; the image work station is at least used for converting the near infrared fluorescence signals into digital images and building a three-dimensional scene corresponding to an operative site; the virtual reality display device is at least used for showing the three-dimensional scene to an operator. The operation navigation system provided by the invention has the characteristics that the sensitivity is high; the moving is flexible; the design, the development and the operation are simple and easy; information is reliable; the safety is high, and the like. The tumor removal operation can be guided in real time; the wide application prospects are realized in the fields of medicine tracing, curative effect evaluation, drug metabolism distribution, tumor early stage detection, stem cell differentiation and restoration and the like.

Description

technical field [0001] The invention specifically relates to a near-infrared imaging-based surgical navigation system, which belongs to the field of medical devices. Background technique [0002] Every year, more than 5 million tumor patients worldwide undergo tumor surgical resection, which is currently the most effective tumor treatment option. Reliable and precise surgical resection can save the lives of tens of thousands of patients. In tumor surgery, tumor identification, determination of tumor resection margins, and identification of metastatic lymph nodes are important factors affecting tumor prognosis. The shortest distance under the microscope between the edge of the specimen and the cancer tissue after primary tumor resection is an important index for evaluating tumor surgery and an important factor affecting the prognosis of tumors. However, most tumor resections have failed to remove cleanly, resulting in Recurrence and metastasis, resulting in loss of life. ...
