Description

Technical Field

[0001] The invention relates to an endoscope visual channel tube, belonging to the technical field of cranial nerve surgery equipment. Background Art

[0002] Existing brain tumor surgeries generally use a neuronavigation system to determine the location of the lesion. Neuronavigation is based on the location of the lesion. After the skin coordinates are attached to the head, a CT or MRI scan is performed. After the patient enters the operating room, the patient is positioned on the operating table and the head is fixed with a head frame after anesthesia. In clinical practice, many pre-set three-dimensional models have errors during craniotomy. The reason is that the brain has internal pressure, which will cause brain deformation after craniotomy. There is also displacement due to changes in the patient's body position. Therefore, the design of the preoperative surgical plan needs to be adjusted due to the displacement of the lesion. However, due to the particularity of the brain tissue, it is impossible to search on a large scale and positioning is difficult. Summary of the invention
