Abstract

The invention provides a stereotaxic apparatus capable of guiding in real time, which comprises a stereotaxic apparatus and a sensor. The stereotaxic apparatus part comprises a chassis, a bow frame and a fastener, wherein the fastener is provided with a guide hole and has adjustable tightness; the sensor part comprises an alpha angle sensor, a beta angle sensor and a distance sensor. Because the sensor is arranged on the stereotaxic apparatus, and an operator can be guided in real time, thereby not only binging convenience for an operation, but also improving the operation quality.

Description

technical field [0001] The invention relates to a stereotaxic instrument, in particular to a stereotaxic instrument which can guide an operator in real time to accurately deliver surgical instruments to a target point when performing craniocerebral surgery on humans or animals. Background technique [0002] Stereotaxic instrument is a kind of intracranial target that can be accurately positioned with the cooperation of image positioning technology, and then surgical instruments such as microelectrodes and puncture needles are accurately placed into specific intracranial targets, and tissue samples are taken and damaged. It is a surgical instrument for point tissue or removal of lesions, and is a common equipment for disease diagnosis, treatment and animal experiments. At present, a known Chinese patent No. is "ZL200720054994.0", and the name is "A Stereotaxic Instrument with Simple Structure". The frame determines two azimuth angles to determine the puncture direction, and ...
