Surgical navigation method and system

Abstract

The invention relates to a surgery navigation method and system. The method includes: performing optical positioning on an ultrasonic probe with a configured optical marking part and a puncture needlewith a configured optical marking part; acquiring the ultrasonic imaging data collected by the ultrasonic probe in real time; generating the position and trajectory of the puncture needle in an ultrasonic image according to the optical positioning information and the ultrasonic imaging data. The system comprises a positioning module, an ultrasonic imaging data acquiring module, a puncture needletrajectory generating module and a display module. The surgery navigation method and system has the advantages that the puncture needle and the ultrasonic probe can be optically positioned, the position and trajectory of the puncture needle in the ultrasonic image collected by the ultrasonic probe can be displayed in real time, X-ray irradiation harm to doctors and patients can be eliminated, thedefects of unclear radiography and nonvisual guidance of traditional ultrasonic guidance are overcome, and the doctors can visually and efficiently master the puncture direction of surgery.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an operation navigation method and system. Background technique [0002] At present, minimally invasive surgery has become a common treatment method due to its characteristics of small trauma and fast recovery, such as percutaneous nephroscopy (PCNL). In minimally invasive surgery, its accurate and rapid surgical puncture is the basis for ensuring the success of the operation and shortening the treatment time. The puncture guidance plays a leading role in the minimally invasive surgery process. The current popular puncture guidance methods mainly include C-arm X-ray guidance and ultrasound guidance. However, C-arm X-ray guidance has radioactivity, which will cause radiation hazards to doctors and patients. ; However, there are problems such as unclear contrast of the puncture needle and insufficient intuition under the guidance of ultrasound, which makes it difficult for doctor...
