Three-dimensional positioning cap for brain surgery positioning and manufacturing method thereof

Abstract

The invention discloses a three-dimensional positioning cap for brain surgery positioning and a manufacturing method thereof. The three-dimensional positioning cap comprises a cap body and at least one positioning fragment, a support frame is arranged on the cap body, and the cap body is divided into eight fragment areas; positioning fragments are arranged in each fragment area; the positioning fragments are at least one of a left front fragment, a right front fragment, a left rear fragment, a right rear fragment, a left rear lower fragment, a right rear lower fragment and two side edge fragments; metal stickers used for marking a top inner point, a coronal rear point and an upper sagittal point are stuck to the positioning fragments; and metal wires used for marking AB, CD, EF, GH, KI, MK, MN and coronal lines are embedded in the positioning fragments. The positioning cap is of an assembled structure, positioning patches, anatomical body surface mark positioning points and positioninglines are arranged on positioning sheets, marking is visual, use is convenient, operation is easy, the price is low, accuracy is high, practicability is high, the navigation function can be partiallyreplaced, and the positioning cap can be easily expanded to vast primary 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...

Problems solved by technology

Then use the navigation equipment for positioning, but during the operation, due to the loss of cerebrospinal fluid, the deformation of the brain tissue, the change of the patient's body position will cause the risk of navigation deviation, which is easy to cause damage to the normal brain tissue, reducing the efficiency and expected effect of the operation

Moreover, the neuronavigation system is expensive and the operation is relatively complicated, so it is only used in a few large hospitals.
