Angle corrector helping to obliquely guide in electrode accurately

Abstract

The invention discloses an angle corrector helping to obliquely guide in an electrode accurately. Side plates are fixedly installed at the left end and the right end of a base, and lug pole inserting holes are formed in the upper portions of the side plates. A dovetail groove fixedly installed on the base is formed between the side plates at the two ends, and a transversely-moving slider is installed on the dovetail groove. A three-dimensional spatial positioning column is fixedly installed on the transversely-moving slider, a three-dimensional spatial positioning point is arranged at the top end of the three-dimensional spatial positioning column, a rotatable three-dimensional spatial positioning column sleeve sleeves the three-dimensional spatial positioning column a height scale is arranged at the top end of the three-dimensional spatial positioning column sleeve, and a toothed plate contact piece fixed on a stereotaxic instrument in a connecting mode is arranged at the outer side end of the base. A transversely-moving slider fixing bolt used for fixing the position of the transversely-moving slider is arranged on the transversely-moving slider. The angle corrector helping to obliquely guide in the electrode accurately is reasonable in structure, and can omit tedious calculation in a test, effectively avoid deviation and help a tester to obliquely guide in the electrode accurately from the vertical upside of the inserting position of the electrode under the condition that a large blood vessel or a blood vessel sinus exists.

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
