no. 1 example

[0033] see figure 1 , the present embodiment provides an ultrasonic navigation system 10, which has a simple structure and is easy to use. At the same time, it can be used for visual aided navigation of the transforaminal mirror, and it can effectively monitor the position of the puncture needle and the channel, avoid damage to the nerve root, and help reduce the radiation exposure of patients and medical staff during the operation. The operation is more visualized and simplified, and it is also conducive to the learning and promotion of transforaminal endoscopic techniques.

[0034] The ultrasonic navigation system 10 provided in this embodiment is used for visualization-assisted navigation of a transforaminal mirror.

[0035]The ultrasonic navigation system 10 provided in this embodiment includes an ultrasonic probe, a magnetic locator 400 and a needle tail navigation locator 200 . The intervertebral foramina endoscopy tool 300 is connected with the ultrasonic navigation s...

Abstract

The invention discloses a visual assisted navigation method for a foramenoscope and an assisting tool for an ultrasonic navigation system and relates to the technical field of ultrasonic navigation. The visual assisted navigation method for the foramenoscope comprises the following steps: acquiring a magnetic resonance target image comprising external calibration and fusing the target image with the assisting tool for the ultrasonic navigation system. The visual assisted navigation method for the foramenoscope and the assisting tool for the ultrasonic navigation system, disclosed by the invention, can be used for visual assisted navigation of the foramenoscope, and can monitor positions of a puncture needle and a channel effectively to prevent nerve roots from being damaged, so that radiation exposure of patients and medical staff in an operation is reduced favorably. The method and tool are more visual and simpler to operate, and learning and popularization of the foramenoscope technology are facilitated.

Description

technical field [0001] The invention relates to the technical field of ultrasonic navigation, in particular to a visual intervertebral foramen mirror-assisted navigation method and an auxiliary tool for an ultrasonic navigation system. Background technique [0002] Endoscopic transforaminal nucleus pulposus extraction is a new minimally invasive technique for the treatment of lumbar disc herniation. This technique is minimally invasive, takes a short time to operate, and has good postoperative curative effect. It is currently being carried out in many hospitals. Due to the microscopic operation and puncture technology, there is a learning curve for this technology, and it is difficult to promote this technology. The transforaminal technique can be divided into two steps, the first step is to establish the channel under X-ray fluoroscopy. After puncturing to the position of the outer opening of the intervertebral foramen with a puncture needle, it is expanded step by step a...
