A method and an apparatus for displaying a part of a brain of a patient is provided. Laser Doppler images are acquired before and after a stimulation. The laser Doppler images comprise information about a blood motion or about a perfusion at the acquired part. Then, the blood motion images acquired before and after the stimulation are compared to identify areas in the brain of the patient which are related to the stimulation. The identified areas are displayed in dependence of topography data representing a topography of the brain.

The invention discloses a disposable retractor for brain operation, comprising a traction-expansion device with a sleeve structure, a guide device, and a connecting lock for connecting the traction-expansion device with the guide device to form a whole, wherein the traction-expansion device has an operating end and an exposed end, the inner wall surface and the outer wall surface of the sleeve structure of the traction-expansion device respectively shrink gradually from the operating end to the exposed end, and two or more than two handles are formed at the operating end of the traction-expansion device; and the guide device has a mounting end corresponding to the operating end of the traction-expansion device to realize installation and a wedge-shaped traction end extending out from the exposed end of the traction-expansion device and capable of sealing the exposed end, and the mounting end has a mounting structure used for fixing the connecting lock. According to the invention, deep operation position can be accurately exposed, at least two operation channels for surgical operation instrument to enter fine tissues are provided, and the design of the traction-expansion device is beneficial to light source hood focusing and binocular vision.

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.

The invention discloses the brain surgery auxiliary device for neurosurgery comprises a base, wherein the upper part of the base is fixed with a transverse plate through a bracket; the upper part of the transverse plate is provided with a lying plate; the upper part of the right end of the lying plate is provided with a transverse rod; the transverse rod is parallel to the lying plate; the top surface of the transverse rod is provided with a through chute; the front side and the rear side in the chute are symmetrically provided with guide grooves; two first sliding blocks are arranged in the chute; inserting blocks are fixed at the front end and the rear end of each first sliding block;the inserting blocks are inserted into the corresponding guide grooves; the first sliding blocks can slide along the length direction of the chute; locking devices are arranged at the left ends of the first sliding blocks; A first threaded hole is formed in the middle of the top surface of the first sliding block on the left side, and a first threaded rod is arranged in the first threaded hole in cooperation. The head fixing device can be properly adjusted according to different head shapes of patients, so that the head of the patients can be better fixed. Besides, the supporting position can be adjusted as well, and thus the operation area can be avoided. This apparatus is convenient to use andsimple to operate.
