Omni-directional angle corrector used in various models of stereotaxic instruments

Abstract

The invention discloses an omni-directional angle corrector used in various models of stereotaxic instruments. Side plates are fixedly installed at the left end and the right end of a base, a lug rod inserting hole is arranged at the top of each of the side plates, a transverse dovetail guide fixedly installed on the base is arranged between the two side plates installed at two ends of the base, a transverse moving sliding block is installed on the transverse dovetail guide, a longitudinal dovetail groove is arranged on the transverse moving sliding block, a longitudinal moving sliding block which can move vertically is arranged on the longitudinal dovetail groove, a three-dimensional space positioning column is fixedly arranged on the longitudinal moving sliding block, a three-dimensional space positioning point is arranged at the top end of the three-dimensional space positioning column, the three-dimensional space positioning column is sleeved by a rotatable three-dimensional space positioning column bushing, a height scale is arranged at the top end of the three-dimensional space positioning column bushing, and a tooth plate contactor is arranged at the outside end of the base. The angel corrector is reasonable in structure, can be used in various models of brain stereotaxic instruments and enables electrodes to insert omni-directionally at any angles on the perpendicular upper portions of electrode inserting positions under the conditions that large vessels or vascular sinuses exist.

Description

technical field [0001] The invention relates to an experimental appliance, which is an omnidirectional angle corrector which can be used on multi-type stereotaxic instruments. Background technique [0002] 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. [0003] When using the brain stereotaxic technique, people usually borrow the up and down position propeller on the arm of the brain stereotaxic instrument, and adopt the method of vertically inserting the electrodes.

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.
