Abstract

The invention provides a machine learning-based intelligent automatic planning method and system for surgical puncture paths and a medical system that can quickly determine the surgical puncture path and the position of the needle entry point, and can be used by a brain stereotaxic instrument or a medical robot arm to realize automatic puncture operations. The planning method of the present invention comprises: step (1), obtains the sample image data of existing case, makes training data and test data; Step (2), designs three-dimensional segmentation depth neural network model, and it is trained; Step (3 ), using the trained three-dimensional segmentation deep neural network model to segment and identify the sample image data of the patient; step (4), constructing a three-dimensional model based on the segmentation recognition results and sample image data; step (5), based on the target position and medical prior information to determine a safe needle insertion restricted area; and step (6), using a three-dimensional space trajectory planning algorithm to complete surgical puncture path planning in the safe needle insertion restricted area.

Description

technical field [0001] The invention belongs to the technical field of artificial intelligence and medical automation, and relates to a machine learning-based intelligent automatic planning method for surgical puncture paths, an intelligent automatic planning system for surgical puncture paths, and a medical system including the intelligent automatic planning system for surgical puncture paths. 3D automatic positioning and navigation platform for medical surgery puncture robot or non-invasive surgery. Background technique [0002] In surgical puncture operations (puncture biopsy, directional hematoma aspiration, directional implantation, etc.), doctors need to repeatedly check computed tomography (CT) images or magnetic resonance imaging (MRI) images on surgical navigation software when planning puncture paths. Surgical planning is accomplished by continuously adjusting the puncture needle trajectory in cross-sectional, sagittal, coronal views of the patient's head or abdomi...
