The invention has simple structure and complete functions, to fix and adjust the animal.
Description
[technical field]
The present invention relates to medical experiment equipment, particularly a kind of animals stereo directed fixing device.
[background technology]
The hydraulic pressure craniocerebral trauma instrument that U.S. NEW SUN company produces is that present craniocerebral trauma research field obtains internationally recognized craniocerebral trauma model apparatus for preparation.The pendulum percussion system of this instrument is reliable and stable, and pressure capsule system is accurately sensitive.But regrettably this instrument does not have supporting with it animal fixing device, and the animal of the animal of causing injury during experiment fixing difficulty, especially waking state is fixing more difficult; The dynamics of causing injury instability; Position and the direction of causing injury (especially contre coup injury position) is difficult to accurate control.Because the rat parietal bone is an inclined-plane, stationary pipes is connected with parietal bone is vertical, and its extended line and brain sagittal plane form an angle, hits and often causes brain stem directly to impact, shake, and the animal breath of causing injury suppresses and death rapidly.The craniocerebral trauma model random error of toy is bigger, and model is difficult for stable the making, has directly influenced the quality of toy craniocerebral trauma experiment, causes the serious wasting of resources simultaneously.What have in the prior art makes animal skull window and hits the effluent pipe mouth butt joint with thing pad holders such as plank, tubs, the direct hand rest animal that has is fixed on the outlet pipe place, and randomness is bigger, and the difference that anthropic factor causes can appear in the process of causing injury of every animal, repeatability is relatively poor, is unfavorable for experimentation.Also have research unit directly to utilize the animal fixed station of animals stereo position finder to go fixedly the craniocerebral trauma model animal of causing injury, but structure do not match and fixed station can not move, rotation and lifting have influenced fixed effect,
[summary of the invention]
Purpose of the present invention is intended to for overcoming the deficiencies in the prior art, and provide a kind of animals stereo directed fixing device, this device can carry out secure and accurate position adjustment to toy, satisfies the requirement of various directions, multiple angles, liftable, rotatable adjusting.
The present invention be address the above problem the scheme that is adopted be the design a kind of animals stereo directed fixing device.It comprises base plate, and is connected bilateral ear locking pin and front tooth retainer ring on the forked frame, it is characterized in that the symmetrical horizontal centre bore of said forked frame is sleeved on the cantilevered axle, and forked frame is rotatable on cantilevered axle, mobile and fixing; The stiff end of said cantilevered axle is fixed on can laterally or on the last moving body of first moving sets that vertically moves, the following fixed body of first moving sets be fixed on the last moving body of second moving sets, and the following fixed body of second moving sets is fixed on the base plate; The mobile axis of said first moving sets and second moving sets is vertical mutually; Said base plate also is provided with the supporting plate of a width less than the forked frame opening at the inferoanterior of forked frame opening, is fixed with an elevating mechanism between supporting plate and base plate.
The invention has the beneficial effects as follows: this animals stereo directed fixing device is simple in structure, the requirement of various directions, multiple angles, liftable, rotatable adjusting be can satisfy, can under the animal waking state, secure and accurate position adjustment be carried out it.And this toy fixture be except being used for hydraulic shock craniocerebral injury instrument, can also be used for falling bodies bump, compressed gas and craniocerebral trauma model the fixing of toy of causing injury such as hit.Thereby can set up that a precision height, stability are strong, good reproducibility, toy hydraulic pressure craniocerebral trauma model easy and simple to handle.The damage location that this model has accurately, the degree of causing injury is stable, can classification, good reproducibility, characteristics that individual random error is little, for the relevant animal experiment study of further carrying out traumatic brain injury in a deep going way is established solid foundation.By this animals stereo directed fixing device, can reliablely and stablely copy the animal model of a lot of clinical common traumatic craniocerebral injuries, for the further investigation of traumatic craniocerebral injury provides good animal experiment platform.
[description of drawings]
Fig. 1 animals stereo directed fixing device sketch map.
Be described in detail with reference to accompanying drawing below in conjunction with embodiments of the invention.
[specific embodiment]
Animals stereo directed fixing device by base plate 15, and is connected compositions such as bilateral ear locking pin 1 on the forked frame 3 and front tooth retainer ring 2.Wherein:
The symmetrical horizontal centre bore of the frame of shape again of fixture is sleeved on the cantilevered axle 5, and forked frame is rotatable and mobile vertically on cantilevered axle, and forked frame can be fixed by fixed knob 4 and cantilevered axle.
The cantilevered axle stiff end 6 of fixture is fixed on the last moving body 7 of transversely movable first moving sets, the following fixed body 9 of first moving sets is that the following fixed body 10 of second moving sets is fixed on the base plate 15 on the last moving body of second moving sets that vertically moves simultaneously.Said moving sets can be to be driven by leading screw 8 to go up the straight-line motion mechanism that moving body moves on slide rail, also can be other moving body straight line is moved and fixed mechanism as: quadric chain, slip and with the fixed mechanism of knob etc. on slide rail.
The base plate of fixture is provided with the supporting plate 14 of a width less than the forked frame opening at the inferoanterior of forked frame opening, is fixed with an elevating mechanism 16 between supporting plate and base plate, and elevating mechanism can be the screw thread elevating mechanism, also can be four connecting rod elevating mechanisms etc.
Animals stereo directed fixing device of the present invention is to stablize the device that toys such as rat, mice, rabbit carry out the craniocerebral injury experiment.For example: behind the rat anesthesia, its health is placed on the supporting plate, again the rat front tooth is hooked on the front tooth retainer ring at the middle part of forked frame, aim at external auditory meatus with the bilateral ear acupuncture, and be tightened ears pin, fixedly rat.In order to obtain testing required fixed position, can be by adjusting the height of bilateral ear acupuncture, and the level angle of forked frame, front and back position, the position, front, rear, left and right of cantilevered axle and the height of supporting plate are realized.In order to satisfy the needs of adjusting precision, on bilateral ear acupuncture elevating lever, be provided with ear tag chi 13; The place is provided with tooth scale 12 at the front tooth retainer ring; Be provided with the rotation scale in cantilevered axle; And the mobile mensuration scale of moving sets etc.
The strike position can be adjusted by changing skull bone window position in the fixing back of toy, prepares the animal model of different damage locations.
