Photoacoustic imaging surgical navigation platform for guiding tumor excision

Abstract

The invention discloses a photoacoustic imaging surgical navigation platform for guiding tumor excision, which comprises photoacoustic imaging equipment, and the photoacoustic imaging equipment comprises a main body, a probe and an image display. The invention discloses the photoacoustic imaging operation navigation platform for guiding tumor excision, and high-frame-rate photoacoustic images andultrasonic images can be provided; deep tissue tumors are visualized in real time; the position of the tumor can be positioned and a tumor boundary is accurately drawn; meanwhile, an aseptic scalpel can be visually improved through photoacoustic imaging; simultaneous development of the tumor and the scalpel under photoacoustic imaging is realized, and the focus can be thoroughly excised by directly viewing the tumor boundary without missing or mistaken cutting, the technology can be used for tumor positioning, boundary defining and accurate excision in the operation process, accurate intraoperative guidance is provided for tumor surgeons, the incompleteness of intraoperative tumor excision is reduced, the thorough excision rate is increased, normal tissue is reserved to the maximum extent,tumor recurrence is reduced, and the survival rate is increased.

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.
