Anklebone fracture modeling instrument for experiment and use method of anklebone fracture modeling instrument

Abstract

The invention provides an anklebone fracture modeling instrument for an experiment and a use method of the anklebone fracture modeling instrument. The anklebone fracture modeling instrument is characterized by comprising a bottom plate, a cooperating plate, a modeling mechanism and an angle adjusting mechanism. Experimental data of multiple fracture directions is obtained through the angle adjusting mechanism, a contrast experiment is performed, and the research range of the experiment is expanded; besides, the fracture directions can be controlled within the optimal interval, and the experimental data is more accurate; and in addition, an included angle can be properly adjusted within the optimal interval according to individual differences of animals. Besides, a stepping motor is used for fixing impact strength, and the torque, the rotating speed and the stroke of the stepping motor can be adjusted and controlled through an external controller, so that the impact strength of the stepping motor on animal ankle bones can be set through the external controller, and the consistency and the repeatability of fracture modeling are improved.

Description

technical field [0001] The invention relates to the technical field of fracture modeling, in particular to an experimental ankle fracture modeling instrument and a use method thereof. Background technique [0002] Ankle bone fracture is a common clinical case, but due to the complex structure of the ankle bone, the diagnosis and rehabilitation process is very difficult. In recent years, more and more attention has been paid to the research on ankle bone fractures. At present, medical clinics often use the ankle bones of animals Fracture modeling experiments are used to conduct clinical research on ankle fractures. However, animal ankle bones are small and thin, and lack special instruments for surgical operations. Therefore, it is difficult to model animal ankle fractures, and it is difficult to accurately control fracture injuries. The experiments are consistent.

[0002] Ankle bone fracture is a common clinical case, but due to the complex structure of the ankle bone, the diagnosis and rehabilitation process is very difficult. In recent years, more and more attention has been paid to the research on ankle bone fractures. At present, medical clinics often use the ankle bones of animals Fracture modeling experiments are used to conduct clinical research on ankle fractures. However, animal ankle bones are small and thin, and lack special instruments for surgical operations. Therefore, it is difficult to model animal ankle fractures, and it is difficult to accurately control fracture injuries. The experiments are consistent. Therefore, the standardization and reproducibility of the operation of the animal ankle bone model is the bottleneck of the development of the discipline of ankle bone fracture, and it is also the reason why clinical medicine pays more attention to the study of fracture modeling technology. Important reasons for mold technology;

[0003] The ankle bone fracture modeling instrument in the prior art fixes the animal through the fixing plate and the fixing device, and then impacts the animal's ankle bone by controlling the osteotomy knife to cause fracture. This way cannot control the impact force of the osteotomy knife, if If the force is too small, the fracture effect will not be achieved. If the force is too high, the animal's ankle bone will be cut off directly, resulting in the failure of fracture modeling. Moreover, the force of the osteotomy knife cannot be controlled, which will also cause the animal's ankle bone to break every time. Deviations in the degree of fracture greatly reduce the consistency and repeatability of the experiment, and affect the effect and progress of the experiment. At present, most of the ankle fracture modeling instruments in the prior art fix the animal platform on a fixed plane, but due to the individual animal Differences and the need for experimental comparison of the direction of the fracture, and the osteotomy knife of the prior art ankle bone fracture modeling instrument can only form a fixed angle with the animal ankle bone, and the angle cannot be adjusted, resulting in the use of the prior art. More experimental data are obtained by comparing the experimental methods to improve the accuracy of the experiment, and due to individual differences in animals, the accuracy of the experimental results is also low
