A Photoacoustic Imaging Surgical Navigation Platform for Guided Tumor Resection

Abstract

The invention discloses a photoacoustic imaging surgical navigation platform for guiding tumor resection, comprising: a photoacoustic imaging device, the photoacoustic imaging device including a main body, a probe and an image display. A photoacoustic imaging surgical navigation platform for guiding tumor resection according to the present invention can provide high frame rate photoacoustic images and ultrasonic images, visualize deep tissue tumors in real time, locate their locations and accurately outline tumor boundaries, and at the same time Photoacoustic imaging can visually improve the sterile scalpel, realize the simultaneous development of the tumor and the scalpel under photoacoustic imaging, and achieve complete resection of the lesion under direct vision of the tumor boundary without missing or mistaken cutting. The positioning, boundary definition and precise resection will provide surgical oncologists with precise intraoperative guidance, which will reduce the incompleteness of tumor resection during operation, improve the rate of complete resection, and preserve normal tissues to the maximum extent, thereby reducing tumor recurrence and improving tumor recurrence. survival rate.

Description

technical field [0001] The invention relates to the medical field, in particular to a photoacoustic imaging surgical navigation platform for guiding tumor resection. Background technique [0002] Cancer is a major global health problem that seriously affects human health. Especially for liver cancer patients, surgical tumor resection is still the main and most effective treatment for most liver cancer patients. However, most patients with liver cancer in my country have experienced the pathological development process from cirrhosis to liver cancer, and there are a large number of regenerative nodules in the liver. During the operation, it interferes with the surgeon's ability to distinguish tumor foci, especially for small liver cancer. . According to statistics, up to 60% of small tumor lesions can neither be seen nor touched. During the operation, it is only by "seeing and touching" to identify the cancer focus, confirm its location and boundary are inaccurate, resulting...

AI Technical Summary

Problems solved by technology

Despite the high sensitivity of fluorescence imaging, it is limited by the limited exogenous contrast agent, and its resolution is low, and the imaging depth is not deep (2-3 mm)

The soft tissue contrast of ultrasound imaging is poor, and the judgment of the tumor boundary is inaccurate

The method based on nuclide imaging requires radioactive reagents, which has radiation and has adverse effects on the health of patients and their contacts.
