Problems solved by technology

However, in the traditional puncture process, in order to grasp the position of the puncture needle tip, it is necessary to perform multiple CT or MRI scans on the patient so that the doctor can obtain the position of the puncture needle in the patient's body, and the doctor needs to have rich surgical experience to be able to More accurately determine the position of the puncture needle, the operation time is long, and the positioning accuracy is low

Abstract

The invention discloses an optomagnetic integrated puncture operation navigation platform. The optomagnetic integrated puncture operation navigation platform is provided with a mark reference system,a register probe, a puncture needle and a navigation terminal, electromagnetic space coordinates of a mark point, a reference point and the tip end of the puncture needle in a electromagnetic space coordinate system and optical space coordinates of the mark point, the reference point and the tip of the puncture needle in an optical space coordinate system are positioned by the register probe, themark reference system and a calibration system on the puncture needle correspondingly. A scanning image including the mark point and an anatomical position are obtained for three-dimensional reconstruction, and thus a three-dimensional image is obtained. The navigation terminal determines virtual space coordinates of the tip of the puncture needle according to the three-dimensional image and the electromagnetic space coordinates and the optical space coordinates of the mark point, the reference point and the tip of the puncture needle, and the puncture needle is displayed in the three-dimensional image according to the virtual space coordinates.

Description

technical field [0001] The invention relates to the field of surgical medicine, in particular to an opto-magnetic integrated puncture operation navigation platform. Background technique [0002] Puncture is to insert a puncture needle into the body to establish a surgical channel for subsequent operations. The key to puncture is speed and accuracy. Only when the puncture needle is inserted into the target site quickly and accurately can the operation time be shortened and bleeding be reduced as much as possible. However, in the traditional puncture process, in order to grasp the position of the puncture needle tip, it is necessary to perform multiple CT or MRI scans on the patient so that the doctor can obtain the position of the puncture needle in the patient's body, and the doctor needs to have rich surgical experience to be able to More accurately determine the position of the puncture needle, the operation time is long, and the positioning accuracy is low.
