Embodiment Construction
[0011] Routine cranial CT or MRI scan (must include the eyeball and external auditory canal), select the surgical target, calculate the puncture coordinate parameters, draw the head drilling point and each landmark line with gentian violet, fix the patient's head in the non-injured positioning frame, routine Disinfect the skin on the head, spread a drape, and under local anesthesia, make a small incision of 0.5 cm long, send the fine puncture needle to the target point along the predetermined puncture path, perform intracerebral surgery such as cell transplantation, suture the scalp incision, and the operation is completed.

The invention provides minimally invasive brain stereotactic operation equipment capable of reducing risk of a patient. In a brain operation, a damage free positioning frame, a gun-shaped skull drill suite, a positioning rule, a positioning block series, a puncture transplant injection needle, a limiting stopper and a spiral brain biopsy needle are used, the brain CT or MRL is unnecessary to be repeatedly made, and the puncture thickness is necessarily measured by a ruler; and according to the designed geometric space coordinate of the equipment, a target point can be reached by direct puncture, so the equipment has the advantages of convenience and flexibility, and reduces risk and cost of the patient.
Description
Technical field [0001] The patent of the present invention relates to a minimally invasive brain-directed surgical instrument. The patent of the present invention is convenient and flexible to use, especially without repeating head CT or MRI; the puncture depth does not need to be measured by a ruler during the operation, and is designed according to the geometric space coordinates of the instrument. The target point can be accurately reached, the intraoperative operation stability is high, the surgical trauma is minimal, and the incidence of complications is extremely low. Background technique [0002] At present, the traditional stereotaxic instrument requires the patient to install a stereotaxic frame on the head, and re-scan with CT or MRI. The operation is cumbersome and time-consuming, which may delay the golden time for optimal treatment, and increase the risk of patient pain and infection and bleeding. medical expenses. Contents of the invention [0003] In order ...
