Structure simple stereoscopic director

Abstract

The present invention provides a steric direction finder with simple structure. Said steric direction finder can be used for accurately feeding the operative instrument into targe point when the operation on human or animal cranium and brain can be made. Said invention includes the following several portions: base plate which is made up by using high-strength rare earth engineering plastics or other material and does not produce pseudoimage interference when the image scanning process is made, fixed nut with guide hole, bow-shaped alpha angle measurer with angular scale, bow-shaped beta angle measurer with angular scale and fastener for regulating tightness.

Description

technical field

[0001] The invention relates to a stereotaxic instrument capable of accurately sending surgical instruments to target points when performing craniocerebral surgery on humans or animals. Background technique

[0002] Stereotaxic instrument is a kind of intracranial target that can be positioned with the cooperation of image positioning technology, and then surgical instruments such as microelectrodes and puncture needles are accurately placed into specific targets in the brain, tissue samples are taken, and target points are damaged. It is a surgical instrument for removing tissue or removing lesions, and is a common equipment for disease diagnosis, treatment and animal experiments. A kind of stereotaxic instrument sold on the domestic and foreign markets at present is based on the principle of three-dimensional coordinate positioning, and after determining the corresponding X, Y, Z three-dimensional coordinates of the target point, the surgical instrument is ...
