Abstract
The utility model provides a bone specimen-embedded fixing rack which comprises a base, and a rectangular frame consisting of vertical frames and a transverse frame, wherein the rectangular frame is fixedly connected with the base; the bone specimen-embedded fixing rack is characterized in that a threaded rotating rod is arranged on the vertical frames of the rectangular frame; the length direction of the threaded rotating rod is parallel to a plane on which the rectangular frame is positioned; an arc-shaped fixing clip is arranged on the inner side of the threaded rotating rod; a crank is arranged on the transverse frame; the lower end of the crank is fixedly connected with a fixing piece perpendicular to the crank. The bone specimen-embedded fixing rack has the beneficial effects that the structure is compact, flexibility and convenience are realized, a fixing area formed between the threaded rotating rod and the fixing piece can be adjusted according to the sizes and shapes of experimental specimens, is suitable for fixing humerus, thighbone and other long bones and also can be used for fixing short bones on different segments of the spinal column, the fixing mode is firm and reliable, and the embedding accuracy and the embedding stability are greatly guaranteed.
Description
Technical field
The utility model belongs to sample fixed mount field, relates in particular to a kind of bone specimen embedding fixed mount.
Background technology
At present, in the biomechanics experiment of orthopaedics basis, usually need first bone specimen to be adopted the materials such as polymethacrylate resin to carry out embedding, so that sample is fixed on the jig of testing machine, bone specimen embedding fixed mount is exactly a kind of structure of fixed preparation while testing front specimen embedding for orthopaedics biomechanics.Bone specimen being carried out to the fixing processes of material embedding such as polymethacrylate resin is: add solvent that its thawing is in a liquid state pulverulent material, bone specimen is put into, then cooling condensing gradually.In cooling condensation process, mostly need to be fixed to unify embedding angle and maintain angle tissue.Prior art generally maintains with manpower when unified embedding angle, and this mode makes material solidification time and embedded material volume change when embedding can cause sample to move, and fixed form is insecure, thereby causes Experiments of Machanics result inaccurate.At present also not to the fixing special mould clamp of organization embedding, especially for different bone tissue sample, there is angle disunity and the problem such as waste time and energy in manpower fixed preparation in practice.How in embedding process, can firmly fix experimental specimen according to embedding object, to have controlled embedding angle is to need at present the problem of solution.
Summary of the invention
The purpose of this utility model is in order to solve in biomechanics experiment, can not more firmly to experimental specimen, carry out the technical matters of embedding, provide a kind of to sample embedding firmly, compact conformation, bone specimen embedding fixed mount that fixed area size is adjustable.
The utility model is realized by the following technical solutions:
A kind of bone specimen embedding fixed mount, comprise base, the rectangular frame being formed by vertical frame and transverse frame, described rectangular frame is fixedly connected with described base, the vertical frame that it is characterized in that described rectangular frame is provided with tommy, the plane parallel at the length direction of described tommy and described rectangular frame place, described tommy inner side is provided with arc fixed card, and described transverse frame is provided with crank, and described crank lower end is fixedly connected with the stator vertical with described crank.
Described tommy is connected by being arranged on the sleeve pipe of arc fixed card one end with described arc fixed card.
Described tommy is evenly distributed on described vertical frame.
The spacing of same the above tommy of vertical frame is 5cm.
Described stator be shaped as disc.
Described arc fixed card is provided with sawtooth.
The beneficial effects of the utility model are: adopt tommy can arbitrarily regulate the distance of horizontal direction, crank and stator can be according to bone specimen size adjustment crank height, and by stator, bone specimen top is formed to effectively fixing pressurization, prevent that in embedding process, sample moves; Embedding angle is convenient to maintain and unify; The utility model compact conformation, flexibly and easily, the fixed area forming between tommy and stator can regulate according to size, the shape of experimental specimen, be applicable to the fixing of the long bones such as humerus, femur, also short bone fixing that can be used for backbone different segment, fixed form is solid and reliable, greatly guarantees the Stability and veracity of embedding.

Fig. 1 is structural representation of the present utility model.
In figure, 1, base, 2, rectangular frame, 3, vertical frame, 4, transverse frame, 5, tommy, 6, arc fixed card, 7, crank, 8, stator, 9, fixed area, 10, sleeve pipe.
Embodiment
Below in conjunction with accompanying drawing, a kind of embodiment of the present utility model is explained.
As shown in Figure 1, the utility model provides a kind of bone specimen embedding fixed mount, comprise base 1, by 2 vertical frames 3 and 1 rectangular frame 2 that transverse frame 4 forms, rectangular frame 2 is fixedly connected with base 1, the vertical frame 3 of rectangular frame 2 is provided with tommy 5, the plane parallel at the length direction of tommy 5 and rectangular frame 2 places, and tommy 5 inner sides are provided with arc fixed card 6, transverse frame 4 is provided with crank 7, and crank 7 lower ends are fixedly connected with the stator vertical with crank 78.In the middle of rectangular frame 2, by forming a fixed area 9 between tommy 5 and stator 8, the size of fixed area 9 is adjustable.In the present embodiment, tommy 5 is evenly distributed on vertical frame 3, and the threaded hole being provided with by vertical frame 3 is connected with vertical frame 3, and on same vertical frame 3, the spacing of tommy 5 is 5cm, stator 8 be shaped as disc, in arc fixed card 6, can be provided with sawtooth (not shown in FIG.), and arc fixed card 6 is connected by the sleeve pipe 10 being arranged between the two with tommy 5, in sleeve pipe 10, is provided with screw thread.
During use, to treat that embedding bone specimen is placed in rectangular frame 2, one end of embedding is placed on base 1 together with embedding device, according to sample shape, fixed angle is different during with embedding, by regulating a plurality of tommies 5 on vertical frame 3 to change arc fixed card 6 positions, make it be close to bone specimen, play horizontal fixation.According to bone specimen height, accommodation zone crank 7 makes disc stator 8 be close to sample top, plays fixing and longitudinal pressing effect, prevents from because embedded material stereomutation causes sample, moving in embedding process.After fixedly completing, wait for after embedded material has solidified and can take off sample.
Above an example of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
