Problems solved by technology

This stereotaxic instrument for three-dimensional coordinate positioning must be accompanied by a set of high-precision three-dimensional coordinate frame, and the size of the frame must be able to cover the entire operation area, so the structure is more complicated, huge, and troublesome to operate. In addition, due to the cost of parts production and the size of parts Directly related, in the case of the same accuracy, the larger the size, the higher the cost, so this stereotaxic instrument is expensive

Embodiment Construction

[0010] Refer to Figure 1. The present invention comprises: a chassis 1, a fixing screw 3 with a guide hole 2, a bow-shaped α angle measurer 4 with an angle scale scale on it, a bow-shaped β angle measurer 5 with an angle scale scale on it, and a guide hole thereon 6 and adjustable elastic fasteners 7, the two ends of the said α angle measurer 4 are respectively hinged along the center line of the chassis 1 and the two limits of the chassis 1, it can rotate left and right, and the β angle measurer 5. After rotating 90 degrees relative to the α angle measuring device, at least one end thereof is hinged to one side of the chassis 1, and it can rotate back and forth relative to the α angle measuring device 4. The said fixing screw 3 is arranged in the middle of the chassis 1, said The fastener 7 is sleeved on the α angle measurer 4 and the β angle measurer 5, so that the α angle measurer 4 and the β angle measurer 4 and β angle measurer The measuring devices 5 are fixed together....

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 ...
