Background
The craniocerebral operation under the neuroendoscopy is an important direction for the development of minimally invasive neurosurgery, and the core of the technology is to further reduce the trauma of the prior operation approach, enlarge the exposure of a focus and increase the chance of directly cutting off pathological changes.
Neuroendoscopy operations can be mainly divided into extra-sheath operations and intra-sheath operations. The external sheath operation is mainly a skull base operation by utilizing the natural physiological cavities of the human body. The typical extra-sheath surgery is nasal subcranial surgery, which can utilize the natural passage of the nasal cavity to provide a more spacious surgical exposure field and can also provide a larger operating angle, and can put a neuroendoscope deep into the operating area to closely observe the anatomical structure of the operating area, so that the past ' standing outdoors to see a house ' is changed into entering indoors to see a house '. Through the observation to anatomical structure's near for the tumour excision is safer and thorough, can obviously reduce the complication, can also reach a better cosmetic effect simultaneously, because need not use the rhinoscope to expand the nasal cavity, consequently the wound of this kind of operation is little, and the patient postoperative is more comfortable, and the postoperative resumes soon, is the genuine minimal access surgery.
The existing retractor for craniocerebral deep operation has the following defects: 1) the front end of the operation sheath tube is not sharp enough, the wound is large, and the intervention is inconvenient; 2) the operation sheath tube is inconvenient to operate, the steering performance is poor, the tension of skin tissues cannot meet the requirement, the operation space of medical personnel is small, and observation and operation are not facilitated; 3) the operation sheath is inconvenient to grasp, and the operation difficulty is high.
