Abstract

The invention discloses a puncture-assisted guiding device, which comprises: a scanning module configured to scan a punctured target to obtain 3D image data of the punctured target and a target body in the target; a three-dimensional positioning module configured to determine a spatial position according to the 3D image data of the punctured target and the target body thereof; a path planning module configured to determine the puncture point and a position of the puncture point when the target body of the punctured target is subjected to puncturing according to at least the 3D image data and the spatial position of the punctured target and the target body to generate a virtual puncture path; a data transmission module configured to send the spatial position coordinates of the virtual puncture path to an AR device, which is convenient to display the inner segment and / or the outer segment of the virtual puncture path through the AR device when the punctured target appears in the field of view of the AR device, wherein the user is assisted to puncture the punctured target according to the virtual puncture path so that the accuracy and efficiency of the operation can be greatly improved.

Description

technical field [0001] The invention relates to the field of clinical medical operations, in particular to a medical operation puncture auxiliary guiding device, system and method. Background technique [0002] Various percutaneous image-guided puncture operations and operations are currently a minimally invasive treatment method widely used in clinical medicine. With the development of precision treatment and minimally invasive treatment. After scanning the human body through imaging equipment such as CT or MR (nuclear magnetic resonance) to obtain a tomographic image, select a suitable target point on the transverse image, and then choose the optimal puncture path, and pass the space between the tomographic image and the coordinate position of the scanning bed Match, find out the position of the needle entry point on the surface of the human body, and then penetrate various instruments required for minimally invasive treatment into the human body according to the pre-desig...
