Angle corrector capable of being matched with various stereotaxic instruments for use

Abstract

The invention discloses an angle corrector capable of being matched with various stereotaxic instruments for use. The angle corrector comprises a base, side plates are fixedly arranged at the left side and the right side of the base, an ear rod insertion hole is formed at the upper part of each of the side plates, a dovetail groove fixedly arranged on the base is arranged between the side plates at two ends, a transversely moving sliding block is arranged on the dovetail groove, a three-dimensional space positioning pillar is fixedly arranged on the transversely moving sliding block, a three-dimensional space positioning tip is arranged at the top end of the three-dimensional space positioning pillar, a rotatable three-dimensional space positioning pillar sleeve is sheathed on the three-dimensional space positioning pillar, a height scale is arranged at the top end of the three-dimensional space positioning pillar sleeve, and a toothed plate contact piece fixedly connected with a stereotaxic instrument is arranged on the outside end of the base. The angle corrector is reasonable in structure, can eliminate the cumbersome calculation in experiment, effectively avoid deviation, and can help experimenters accurately and obliquely guide an electrode into the position vertically above an electrode insertion part under conditions that large blood vessels or vascular sinuses exist.

Description

technical field [0001] The invention relates to an experimental appliance, which is an angle corrector matched with a stereotaxic instrument. 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 under the living conditions of experimental animals with less damage to the brain structure, so as to observe or influence the development of tiny brain regions of these animals. Functionality changes. 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. However, if the...

Problems solved by technology

However, considering that the electrode cannot be completely guaranteed to be vertical during preparation, and when the electrode is installed on the electrode holder of the operating arm, it may form an angle with the operating arm that is not easy to be observed by people.

Therefore, using theoretically calculated values ​​​​to insert electrodes, there will be deviations
