Problems solved by technology

[0003] During the entire operation, it is most important to accurately send the transforaminal endoscope to the site that requires surgery. Existing operations mainly rely on the experience of doctors. For inexperienced doctors, the operation is more difficult, and it is easy to damage the nerves in the spinal canal

Embodiment 1

[0050] Embodiment one, as figure 1 , figure 2 The system block diagram of the opto-magnetic integrated transforaminal mirror navigation platform shown, the navigation platform is provided with:

[0051] Marking reference system 100, used for demarcating reference points and multiple marking points 121 in electromagnetic space coordinate system and optical space coordinate system;

[0052] Registering the probe 200, used to calibrate the marking point 121 in the electromagnetic space coordinate system and the optical space coordinate system respectively;

[0053] The marking system 300 is used to mark the tip of the intervertebral foramina mirror A in the electromagnetic space coordinate system and the optical space coordinate system respectively;

[0054] The navigation terminal 400 is used to establish an electromagnetic space coordinate system, an optical space coordinate system and a virtual space coordinate system;

[0055] It is used to respectively locate the marker ...

Abstract

The invention discloses an opto-magnetic integrated intervertebral foramen mirror navigation platform, which is provided with a marking reference system, a registration probe, a marking system and a navigation terminal. The electromagnetic space coordinates of the tip of the foraminal lens in the electromagnetic space coordinate system, and the optical space coordinates in the optical space coordinate system. And obtain the scanned image including the marker points and anatomical positions for three-dimensional reconstruction to obtain a three-dimensional image. The navigation terminal determines the tracking coordinates of the tip of the intervertebral foramina lens according to the three-dimensional image, as well as the marker points, reference points, electromagnetic space coordinates, and optical space coordinates of the tip of the intervertebral foramina lens, and displays the vertebra in the three-dimensional image according to the tracking coordinates. Hole mirror.

Description

technical field [0001] The invention relates to the field of surgical medicine, in particular to an opto-magnetic integrated intervertebral foramen mirror navigation platform. Background technique [0002] A transforaminal speculum is a lighted tube that enters the foramen from the side or rear of the patient's body and operates in the safe working triangle. The protruding nucleus pulposus, nerve roots, dural sac and proliferating bone tissue can be clearly seen through the transforaminal microscope. Then use various grasping forceps to remove the protruding tissue, remove the bone under the microscope, and repair the damaged fibrous annulus with radiofrequency electrodes. It is the minimally invasive treatment of intervertebral disc herniation with the least trauma to the patient and the best effect among similar operations. [0003] During the entire operation, it is most important to accurately send the transforaminal endoscope to the site that requires surgery. Existin...
