Laser locator for brain stereotactic localization

Abstract

The invention provides a laser locator for brain stereotaxic positioning, relates to the technical field of test tools, and solves the problems that in the prior art, when a brain stereotaxic instrument is used, positioning is inaccurate and infection is possibly caused when a marker pen is used for marking the position on the surface of a skull. The laser positioner comprises a base connector, a position adjusting mechanism and a laser generator, the laser generator is connected with the base connector through the position adjusting mechanism, the base connector is connected with the brain stereotaxic apparatus, and the spatial position of the laser generator can be adjusted through the position adjusting mechanism. When the laser locator is used, the laser locator is firstly fixed on a brain stereotaxic instrument base through a base connector; then a target point is found on the surface of the skull through the datum point by utilizing a brain stereotaxic instrument, and when the needle point is close to the surface of the skull, the position adjusting mechanism is adjusted, so that a laser point emitted by the laser generator is accurately positioned on the skull below the needle point of the microsyringe, and whole-course real-time marking can be realized in the subsequent polishing process.

Description

technical field [0001] The invention relates to the technical field of test tools, in particular to a laser localizer for brain stereotaxic. Background technique [0002] Stereotaxic apparatus is an instrument used to precisely locate the brain regions of experimental animals and inject drugs or tumor cells in specific locations. When using the traditional brain stereotaxic instrument, first find the reference point on the skull surface, then adjust the X and Y axes of the microinjector fixed on the brain stereotaxic instrument according to the data of the target area, and then adjust the Z axis to lower the height of the microinjector, and then adjust the height of the microinjector on the needle tip. After getting close to the skull surface, mark the position with a marker pen, then remove the microsyringe, use a drill to make a hole on the marked point of the skull, and then move the microsyringe back to the previous position to inject through the bone hole. There are se...
