Neurosurgery navigation operation automatic registration reference frame

Abstract

The invention provides a neurosurgical navigation operation automatic registration reference frame which is composed of a reference frame assembly and a reference frame base assembly, and the reference frame assembly comprises a reference frame body; the reference frame base assembly comprises a reference frame base, at least one positioning device is arranged in the middle of the reference frame body, at least one light reflecting ball mounting base is arranged on the outer ring of the positioning device, and a light reflecting ball is arranged on the light reflecting ball mounting base; the positioning device is connected with the end face of one side of the reference frame base. The end face of the other side of the reference frame base is provided with a plurality of positioning balls and then pasted to the head of a patient through a double-sided foam tape. The frame is simple in structure, the defects of traditional point registration and surface registration are overcome, meanwhile, the disposable reference frame base assembly is adopted, the CT scanning device can be conveniently attached to the head of the patient to complete CT scanning operation, and particularly, the reference frame base assembly is small, exquisite and very light in weight, and normal activities of the patient cannot be affected.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an automatic registration reference frame for neurosurgical navigation operations. Background technique [0002] The clinical application of the neurosurgery navigation system has proved that it has become an important tool in neurosurgery. Before neurosurgical navigation surgery, CT scanning is performed on the patient to obtain image data of the lesion and the patient's head. This process is generally carried out in the CT room of the hospital. In the process of surgical preparation, the data space formed by the patient's image is matched with the actual physical space of the patient, so that the two spaces are unified. This process is called registration. [0003] After registration, the doctor performs the surgical operation according to the real-time feedback of the surgical instrument position information from the navigation device. [0004] The registration work ...
