Description
The application is application number: 201210044414.5, and the applying date: 2012.2.27, what title " can be mated with multiple stereotaxic instrument the angle corrector of using " divides an application.
Technical field
The present invention relates to a kind of experimental apparatus, is a kind of angle corrector of using of mating with 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 in 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 is people, to carry out brain stimulation, record cell electric discharge, while carrying out experiment such as micro-injection and push-pull perfusion, conventionally considers a technology of using.
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 the situation that electrode occurs during insertion fractureing or causes intracerebral hemorrhage.So the insertion of people's electrode when meeting these situations will be inserted after conventionally will changing inclination certain angle into by vertical insertion.
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 on the brain solid positioner of other models.And our angle corrector of application can be used on multiple brain solid positioner.
Electrode inserts after changing inclination certain angle into by vertical insertion, theoretically, can by calculating, obtain corresponding compensating parameter by the relation on each limit of triangle.But consider that electrode can not guarantee completely vertically in preparation, and when electrode is installed to the electrode jaw of motion arm, may form the angle that people are difficult for observing with motion arm.So carry out electrode insertion with calculated value, there will be deviation.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, effectively avoid the angle corrector that mating with multiple stereotaxic instrument of deviation used of avoiding of deviation.
Technical solution of the present invention is:
A kind of angle corrector that can mate with multiple stereotaxic instrument use, 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 dovetail groove on base, on dovetail groove, fill transverse shifting slide block, on transverse shifting 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.

Tooth plate contact is rectangular in shape.
Work process of the present invention:
(1) angle corrector is arranged on stereotaxic instrument
According to the requirement of the selected stereotaxic atlas of experiment, adjust the ear bar tip of stereotaxic instrument and the difference in height of tooth plate.By the two ear bar jacks (1) of picking up the ears on bar insertion angle corrector side plate (2), and tooth plate contact (10) is placed on the tooth plate of stereotaxic instrument.Regulate two ear bars, angle corrector is positioned in the middle of stereotaxic instrument, tighten ear bar and tooth plate set bolt on stereotaxic instrument.Rotatable three-dimensional fix column sleeve pipe (13) is inserted to three-dimensional fix post (4).
(2) experimental requirement arranges required benefit and tastes angle
According to the positioning requirements of experiment, determine the left and right of location and upper and lower spatial parameter (now the front and back position of location be take zero point as reference).According to the transverse shifting slide block 6 of the left and right parameter adjusting angle corrector of this anchor point, after the position, left and right of three-dimensional fix point 3 is consistent with left and right positional parameter, with transverse shifting slide block set bolt, will fix with position, transverse shifting slide block left and right, and find out the consistent upper-lower position of positional parameter from the altitude scale 12 of three-dimensional fix column sleeve pipe, this point (A point) is acted on to the left and right of our location and upper and lower locus.Motion arm by stereotaxic instrument with electrode jaw and electrode is installed on the base of stereotaxic instrument.According to requirement of experiment angle, regulate the angle adjustable bolt of position finder motion arm, motion arm is adjusted to above-mentioned angle, tighten the angle set bolt on motion arm, maintain the angle of this formation.Then by all around on adjustment operation arm respectively and height knob, electrode tip is aimed to A point.Record motion arm angle of inclination now and the upper and lower and left and right position readings of motion arm, as the angle compensation parameter of this experiment.
(3) by required locus in electrode loading test animal brain
The motion arm of angle compensation parameter adjustment good position will be pressed, by regulating its height knob electrode position that moves up.Motion arm is temporarily removed from position finder base, when preventing on stereotaxic instrument fixedly animal, encountered electrode tip and affect positioning precision.Laboratory animal is fixed on position finder on request.Then motion arm is retightened on the base of position finder by previous motion arm angle of inclination and left and right location parameter.The experimental position that requires adjustment operation arm front and back, meets the requirements left and right, the front and back parameter of location completely again.After last, by adjusting height knob, eletrode tip is sent to the three-dimensional space position that we test the laboratory animal brain needing.
