All-angle compensation corrector for stereo positioning instrument

Abstract

The invention discloses an all-angle compensation corrector for a stereo positioning instrument. The left end and the right end of a base are respectively and fixedly provided with a side plate, a lug rod inserting hole is formed in the upper portion of each side plate, and a transverse dovetail guide rail which is fixedly mounted on the base is arranged between the two side plates at the two ends. The transverse dovetail guide rail is provided with a transverse movement sliding block, the transverse movement sliding block is provided with a longitudinal dovetail groove, and a longitudinal movement sliding block which can move longitudinally is arranged in the longitudinal dovetail groove. The longitudinal movement sliding block is fixedly provided with a three-dimensional space positioning pillar, a three-dimensional space positioning tip is arranged at the top end of the three-dimensional space positioning pillar, the three-dimensional space positioning pillar is sleeved with a rotatable three-dimensional space positioning pillar sleeve, and an altitude scale is arranged at the top end of the three-dimensional space positioning pillar sleeve. A toothed plate contact element is arranged at the end of the outer side of the base. The all-angle compensation corrector for the stereo positioning instrument is reasonable in structure, can be used in various models of brain stereo positioning instruments and can help people achieve omnibearing any-angle inserting of an electrode at the position over the insertion part of the electrode under the condition that large blood vessels or blood vessel sinuses exist.

Description

[0001] This application is a divisional application with application number: 201210179614.1, application date: 2012.06.04, and the name "omnidirectional angle corrector that can be used on multi-model stereotaxic instruments". technical field [0002] The invention relates to an experimental appliance, which is an omnidirectional angle corrector which can be used on multi-type stereotaxic instruments. Background technique [0003] In many cases of neuroscience research, people need to insert experimental electrodes with different functions into the desired parts of the deep brain to observe or affect the functions of small brain regions of these animals under the living conditions of experimental animals, with less damage to the brain structure Variety. This technique is called stereotaxy. It is a technology that is usually considered when people perform experiments such as electrical stimulation in the brain, recording cell discharge, microinjection and push-pull perfusion...

Problems solved by technology

However, if there is a large blood vessel or vascular sinus vertically above the electrode insertion site, if the vertical electrode insertion method is still used, the electrode may break during the insertion process.
