Abstract
The utility model provides a rat sour jujube is fixer suddenly, two three -dimensional dead levers that include the mutual interlock of base and perpendicular to base, three -dimensional dead lever includes the fixed perpendicular connecting pipe of perpendicular base, perpendicular connecting pipe inside callipers has the vertical fixation pole, the vertical fixation pipe is direct with stepping up the screw fixation with the vertical fixation pole, even there is transverse fixing rod the side of vertical fixation pole, it steps up the screw to be equipped with between transverse fixing rod and the vertical fixation pole, transverse fixing rod's the other end even has the vertical fixing pole, use the screw rod even to have the furcella fixation clamp on the vertical fixing pole, be equipped with the fixed screw on the screw rod, the fixation clamp side is equipped with the reinforcement screw of fixing with the vertical fixing pole, be equipped with the spring in the fixation clamp, the clamping part of furcella fixation clamp is equipped with the furcella. The utility model discloses fixed effect is better, is applicable to the not rat of equidimension.
Description
Technical field
The utility model relates to a kind of rat spinous process fixator, belongs to animal used as test medicine equipment.
Background technology
Spinal cord injury is one of difficult problem of research at present, and rat is the most frequently used animal used as test, and backbone in experimentationStability most important, it can reduce the additional injuries that non-paathogenic factor causes spinal cord, makes experimental result more accurate.There is no at present the domestic apparatus that is specifically designed to fixing experimental rat backbone, and the spine fixator of import is expensive, and establishesIt is reasonable not to count, and uses inconvenience.
There is no at present domestic rat spinous process fixator, the fixator of import is not only expensive, and designs and owe desirable,Use very inconvenient. Its geometrical clamp adopts sector open design, and when clamping, often rear portion clamps, and still pine of front portion,It is desirable that spinous process fixed effect is owed, and easy pinch off spinous process, loses the effect of spinal fixation.
Summary of the invention
In order to solve above technical problem, the utility model provides a kind of rat spinous process fixator.
The technical solution of the utility model is as follows:
A kind of rat spinous process fixator, comprises base and two three-dimensional fixed bars perpendicular to the mutual interlock of base, instituteState the vertical tube connector that three-dimensional fixed bar comprises that vertical base is fixing, in vertical tube connector, card has vertical fixed bar, vertically fixingPipe is directly fixed with stepping up screw with vertical fixed bar, and vertically the side of fixed bar is connected with horizontal fixed bar, horizontal fixed bar andBetween vertical fixed bar, be provided with and step up screw, laterally the other end of fixed bar is connected with longitudinal fixed bar, longitudinally on fixed bar, usesScrew rod is connected with furcella geometrical clamp, and screw rod is provided with fixed screw, and geometrical clamp side is provided with the reinforcing spiral shell fixing with longitudinal fixed barSilk; In described geometrical clamp, be provided with spring, the clamping part of furcella geometrical clamp is provided with furcella.
The beneficial effects of the utility model:
, improved spinous process geometrical clamp, adopt the fixing spinous process of mode of Multi-contact interlock, although dwindled geometrical clampWith the overall contact area of spinous process, but increased fixing firm degree, and can not be caught broken spinous process, fixed effect is betterGood;
, different size geometrical clamp go for the rats of different sizes;
, fixed bar can be up and down and rotary moveable, makes fixing orientation more diversified;
, longitudinally fixed bar can not rotate, and can ensure the vertical of spinous process geometrical clamp.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is base; 2 for stepping up screw; 3 is vertical fixed bar; 4 is horizontal fixed bar; 5 is longitudinal fixed bar; 6For spring; 7 is furcella geometrical clamp; 8 is fixed screw; 9 for reinforcing screw; 10 is furcella.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As Fig. 1 be as described in rat spinous process fixator, comprise base 1 and two three-dimensionals perpendicular to the mutual interlock of baseFixed bar, described three-dimensional fixed bar comprises the vertical tube connector that vertical base is fixing, in vertical tube connector, card has vertical fixed bar2, vertical stationary pipes is directly fixing with stepping up screw 2 with vertical fixed bar 2, and the side of vertical fixed bar 2 is connected with horizontal fixed bar4, laterally between fixed bar 4 and vertical fixed bar 2, be provided with and step up screw 2, laterally the other end of fixed bar 4 is connected with longitudinal fixed bar5, longitudinally on fixed bar 5, use screw rod to be connected with furcella geometrical clamp 7, screw rod is provided with fixed screw 8, and furcella geometrical clamp 7 one sides are establishedThere is the reinforcing screw 9 fixing with longitudinal fixed bar 5; In described geometrical clamp, be provided with spring 6; The clamping part of furcella geometrical clamp 7 is provided withFurcella 10.
In the utility model, the function of base is mainly to connect and fixed vertical fixed bar, according to the size of rat, fixingBar can be up and down and rotary moveable, the convenient locus that regulates geometrical clamp. The height that base supports can regulate, thereby makes the endThe ideal height of seat in needs, and keep the level of base. Each fixed bar is connected to each other by connector, can be at three dimensionsIn arbitrarily regulate the position of geometrical clamp, not only convenient installation, and can fix from multiple orientation the backbone of rat. Longitudinally fixingBar can not rotate, and can make spinous process geometrical clamp keep vertical, ensures that rat spine can not rotate. Stinging of spinous process geometrical clampClose, adopt the fixing mode of Multi-contact, accurately interlock, firmly fixes spinous process more, and prevents from damaging spinous process. MultipleThe geometrical clamp of size is applicable to the rat of different sizes, and adaptability is stronger.
