Abstract

The invention discloses a stereotaxic cap for positioning in brain surgery and a manufacturing method thereof. The stereotaxic cap includes a cap body and at least one positioning fragment, wherein the cap body is provided with a support frame, and the cap body is divided into 8 fragments area; positioning fragments are set in each fragment area; the positioning fragments are at least one of left front fragments, right front fragments, left rear fragments, right rear fragments, left rear lower fragments, right rear lower fragments and two side fragments; Metal stickers for marking the inner apical point, posterior coronal point, and superior sagittal point are pasted on the positioning fragment; metal wires for marking AB, CD, EF, GH, KI, MK, MN, and coronal line are embedded in the positioning fragment. The present invention is an assembled structure, and positioning posts, anatomical body surface landmark positioning points, and positioning lines are arranged on the positioning sheet, and the marking is intuitive, easy to use, simple to operate, low in price, high in accuracy, and strong in practicability, and can partially replace the navigation function , easy to expand to the majority of grassroots hospitals.

Description

technical field

[0001] The invention relates to a stereotaxic cap for positioning in brain surgery and a manufacturing method thereof, belonging to the technical field of cranial nerve surgery medical equipment. Background technique

[0002] Existing brain surgery generally uses a neuronavigation system to determine the lesion site. Neuronavigation is based on the lesion site, after pasting the skin coordinates on the head, and performing CT or MRI scanning. After entering the operating room, the patient is positioned on the operating table, and the head is fixed with a head frame after anesthesia. Then use navigation equipment for positioning, but during the operation, due to the loss of cerebrospinal fluid and deformation of brain tissue, the patient's body position changes will cause the risk of navigation deviation, which is likely to cause damage to normal brain tissue, reducing the efficiency and expected effect of the operation. Moreover, the neuronavigation system i...
