Description
The application is application number: 201210179614.1, and the applying date: 2012.06.04, the dividing an application of title " the omnibearing angel-correcting device that can use on polytypic stereotaxic instrument ".
Technical field
The present invention relates to a kind of experimental apparatus, is a kind of omnibearing angel-correcting device that can use on polytypic stereotaxic instrument.
Background technology
In a lot of situations of Neuroscience Research, people need to be under laboratory animal condition of living body, and the structure of less damage brain is inserted the experimental electrode of difference in functionality the desired area in brain deep, observes or affect the changes of function of these animal brain tiny areas.This technology is called as brain stereotaxic technique.It carries out brain stimulation people, records cell electric discharge, while carrying out the item experiments such as micro-injection and push-pull perfusion, is the technology that consideration is used conventionally.
When making to require mental skill stereotaxic technique, people normally use the upper-lower position propeller on brain solid positioner motion arm, adopt the vertical method of inserting of electrode.If but at electrode, insert the vertical direction at position, and have in the situation of large blood vessel or Sinusoidal, still use the vertical method of inserting of electrode, will face electrode and occur during insertion situation about fractureing.So people are when meeting these situations, the insertion of electrode will change omnibearing arbitrarily angled insertion into by vertical insertion conventionally.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, effectively avoid the stereotaxic instrument angle corrector of the omission troublesome calculation of deviation.
Technical solution of the present invention is:
A kind of omnibearing angel-correcting device that can use on polytypic stereotaxic instrument, it is characterized in that: comprise base, two ends, base left and right are fixedly mounted with side plate, side plate top is provided with ear bar jack, between two end side panels, arranging and be installed in the horizontal dovetail guide on base, laterally on dovetail guide, fill transverse shifting slide block, longitudinal dovetail groove is set on transverse shifting slide block, the slide block that vertically moves that can vertically move is longitudinally set in dovetail groove, vertically move and on slide block, be fixedly mounted with three-dimensional fix post, three-dimensional fix capital end arranges three-dimensional fix point, on three-dimensional fix post, be set with rotatable three-dimensional fix column sleeve pipe, three-dimensional fix post cannula tip arranges altitude scale, the tooth plate contact being connected with stereotaxic instrument in the outboard end setting of base.
On base, be provided for understanding the base scale of transverse shifting slide position; The horizontal scale of transverse shifting slide block that is used in conjunction with, understands transverse shifting slide position with base scale is set on transverse shifting slide block.
On transverse shifting slide block, be provided for the transverse shifting slide block set bolt of fixed lateral moving slider position; Vertically move on slide block, be provided for fixedly vertically moving slide block position vertically move slide block set bolt.
Tooth plate contact is rectangular in shape.
At the dovetail groove position of transverse shifting slide block, be provided for understanding the longitudinal scale of transverse shifting slide block that vertically moves slide position; Vertically move on slide block arrange with the longitudinal scale of transverse shifting slide block be used in conjunction with, understand vertically move slide block position vertically move slide block scale.
The present invention is rational in infrastructure, can on the brain solid positioner of Multiple Type, use, and help us to complete the vertical direction of inserting position at electrode, has in the situation of large blood vessel or Sinusoidal the omnibearing arbitrarily angled insertion of electrode.
There is at present the brain solid positioner of several manufacturer production different models both at home and abroad, but only have the external manufacturer production of minority and the supporting angle corrector of itself position finder, be available for users to choose.These angle corrector generally can not be used at the brain solid positioner of his model.And our the omnibearing angel-correcting device that can use on polytypic stereotaxic instrument of application can use on multiple brain solid positioner.
Electrode changes omnibearing arbitrarily angled insertion into by vertical insertion, theoretically, can calculate and obtain corresponding compensating parameter by solid geometry relation.But to general experimenter, calculate more complicated.In addition electrode can not guarantee completely vertically in preparation, and electrode may form the angle that people are difficult for observing with motion arm while being installed to the electrode jaw of motion arm.So carry out electrode insertion with calculated value, may occur deviation.And the omnibearing angel-correcting device that can use on polytypic stereotaxic instrument of our application can omit calculate in experiment loaded down with trivial details, and avoid above-mentioned deviation.Complete the comprehensive arbitrarily angled insertion of electrode.
