Description

one

The invention relates to the field of veterinary and biologic research.

A well-known installation, containing a bed with fixed pelvic and spinning clamps, is made in the form of a reamer in iZhnyh sponges, a movable table with a head donator, including ears and eye squeezes and a jaw frame, and racks with stereotactic, and heads. However, the spinal or ro.TOiBHOM. Brain of an animal can be operated at a time only by the adductal stereotactic head, so it is impossible to glue the head with one head from the other, to the brain. The cherale of the animal is recorded using the Centagiota stereotactic system, while the majority of the stereotactic atlases are composed of the Holesl | I-Claippi system. The dorsal and pelvic ends are designed in such a way that one sponge is a nonshift, and the second is displaced with respect to it. This creates the possibility of the displacement of individual parts of the body as it is alive at the bottom of its function.

In the proposed installation, for widening. with stereotoxic heads.

In addition, for precise and rigid fixation of the skull of the animal in the stereotaxic coordinate system, the maxillary frame of the installation is made with the possibility of rotation in three mutually perpendicular planes and full fixation in a predetermined position. And for the convenience of controlling clips and

releasing the experience floor, the sliding jaws of the pelvic and spinal clamps are placed into the groove of the rod, through which an adjusting screw controls the clamps. FIG. 1 depicts stereotactic

installation, general view; in fig. 2 - jaw frame, incision; in fig. 3 - the same plan view; in fig. 4 - spinal or pelvic clamp; in fig. 5 is a section along A-A in FIG. one.

Ustanoika sod.rzhit bed 1 with grooves 2,

in (which movable sliders 3 are placed. The slide blocks have threaded holes for fastening the racks with stereotactic heads 4. To the frame "repetition of the movable table of the holder 5, on which the stand 6 is mounted. Head holder B (includes a bracket 7 fixed to the stand 6) which can be fixed in any position when rotated around the longitudinal axis, the turn dial is applied on the stand 6. Ke 6. On the bracket 7 there are columns 8 with holders

for goosenecks. 9. The bar 10 with the hamutyh. 11. It can slide along the rods 12 to rotate together with them from O to 45 ° around the lugs 9. In the pipette 10, the eye glands 13 and the jaws of the paiMKa 14 are installed. Pfeplin rod 15, which by another K01NTs01M slides freely over sleeve 16 and in clamping 17, which tightens the ends of xoiMyTHKa 18, mounted on barbell 10. Such a jawbone of the jaw frame allows it to maximize its mobility: moving along the axis of the installation; rod 10, turn away from the rod, turn around with erlsh 15 n BOiKipyr yinta rotation axis 17. The complete jaw fixing frame 14 from all movements is performed with .po1moschyu clamp 17 that vie.

Pelvic and dorsal clamps are used to fix the pelvis and back of the animal. The clamps consist of two jaws 19 (for the pelvis) and 20 (for the back), and pins 21, which are in place of the connection, are included in the symmetrical longitudinal grooves 22 of the oval base 23. The screws securing the other two grooves 24 sponges c) V1IL1ke 25. A spindle 26 with threaded holes, through which a screw 27 with a right and left thread passes through a clamping screw, is mounted on a sliding fit. The sponges are located in the groove of the rod 28, and the clamping 1V1NT 27 - / inside this rod. The stand with the stereo head 4 is attached to the slide 3 by the screw 29. With the screw fixed, the stand 4 is fixed in the designated place strictly vertically with the help of the guide pin 30 fixed in the stand. The rack can be removed from the manhole and installed in any other groove, where it is necessary for the experiment, turned out in VI1NT 29 from the slider 3. In order to avoid falling out of the rack, the screws 31 are screwed into it. The skull of the experimental animal is fixed in the head holder by the ears 9, the ocular grips 13 and the maxillary frame 14. The animal's upper jaw presses the frame 14 against the ocular clamps 13.

The torso of the animal is fused with a system of clamps including dorsal and pelvic clamps and 1M spinal clamps. Due to the presence of longitudinal grooves on both sides of the stan1na and in the table head stand

with stereotactic 1M, and the head with the installed elactrodes in them. They can be placed anywhere in the installation. The experience can be made with non-split heads on different parts of the spinal and head

brain abyss.

Present Invention

Claims (3)
