Description
Technical field
The invention belongs to medical experiment apparatus field, be specifically related to a kind of spring being applicable to animal foot Skeletal muscle injury
Formula percussion device and striking method.
Background technology
Skeletal muscle injury is one of common injury in motion, in the injury types of various sports events, muscle injury
Shared ratio is the highest, and its incidence rate accounts for the 10%～55% of athletic injury sum, wherein contusion injuries and the incidence rate of tension injury
Account for more than 90%.Skeletal muscle contusion injuries is that muscle suffers, caused by the compressing violence of direct passivity, multiple to be born in antagonism motion item
In mesh, quadriceps femoris and gastrocnemius are the predilection sites of skeletal muscle contusion injuries.Owing to after damage, muscle fiber is destroyed, produce
Microcirculatory disorder and the infiltration of inflammatory cell and the organization of hematoma etc. of muscular tissue, to athletic motor capacity, motion longevity
Life all constitutes potential threat.Although muscle injury can be repaired by anathrepsis, but the 26S Proteasome Structure and Function of muscle
Not necessarily can return to one's perfect health.The damage of skeletal muscle can have a strong impact on the contractile function of skeletal muscle, destroys myofiber plasma membrane and base
The integrity of counterdie, and ultimately cause the death of cell, thus cause the further damage of skeletal muscle.Lead in sports medical science research
In territory, the research of Skeletal muscle injury pathomechanism and the discussion of prevention, treatment and measure of rehabilitation always are focus.
In order to deepen the understanding to Skeletal muscle injury, probe into Skeletal muscle injury, especially the occurrence condition of contusion injuries, skeleton
The mechanism of muscle injury, Fibrotic inducement and repairing condition after Skeletal muscle injury, we need to carry out Research of Animal Model for Study.
The contusion injuries model of animal is widely used in the research of Skeletal muscle injury, but modeling means exist certain defect at present.At present
Conventional Skeletal muscle injury modeling method is that contusion injuries, i.e. weight injure by a crashing object.Conventional model animal has mice, rat, and rabbit.
Injuring method by a crashing object is: after model animal anesthesia, dorsal position gives away one's position muscle；Target muscles is injured by a crashing object along fixation locus with weight, or
One wedge is hit transmitter as pounding, is positioned on target muscles, hold pipeline on wedge, make weight along pipeline in wedge shape
Freely falling body directly over thing, pounds wedge, and power is transmitted on destination organization by wedge, ultimately causes contusion injuries (such as Fig. 4 institute
Show).There are problems in existing modeling method, as needed many people to complete: fixed model animal, throws away weight, fixed-piping, operation
Weight etc.；Confounding Factor is many: cannot ensure that weight height is completely the same, and weight and wedge there may be friction, cause modeling
Repeatable poor.
So, a kind of contusion injuries beating device need to be designed, it is ensured that the repeatability of experiment, save manpower.
