Angle corrector for effectively helping experimenter perform electrode insertion operation

Abstract

The invention discloses an angle corrector for effectively helping an experimenter perform an electrode insertion operation. The angle corrector comprises a base, wherein side plates are fixedly mounted at the left and right ends of the base; ear rod holes are formed in the upper parts of the side plates; a dovetail groove fixedly mounted on the base is formed between the side plates at the left and right ends of the base; a transverse movement sliding block is mounted on the dovetail groove; a three-dimensional space positioning column is fixedly mounted on the transverse movement sliding block; a three-dimensional space positioning tip is arranged at the top end of the three-dimensional space positioning column; a rotatable three-dimensional space positioning column sleeve pipe is sleeved on the three-dimensional space positioning column; a height scale is arranged at the top end of the three-dimensional space positioning column sleeve pipe; a toothed plate contact piece fixedly connected with a stereotaxic instrument is arranged on the outer side of the base; and the toothed plate contact piece is right-angled. According to the angle corrector, the structure is reasonable, the tedious calculation in an experiment can be omitted, the deviation can be effectively avoided, and the experimenter can be helped to finish an accurate tilting electrode insertion operation under the circumstance that a large blood vessel or blood vessel sinus is over an electrode insertion part.

Description

[0001] This application is a divisional application with application number: 201210044414.5, application date: 2012.2.27, and the name "angle corrector that can be matched with various stereotaxic instruments". technical field [0002] The invention relates to an experimental appliance, which is an angle corrector matched with a stereotaxic instrument. 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 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. [0004] When using th...

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
