Spring type animal beating device and method

Abstract

The invention discloses a spring type animal beating device. The spring type animal beating device comprises a base, a fixator and an indication panel and beating parts, wherein the base is connected with the beating part through a screw, the indication panel is composed of a perpendicular panel and a slide panel, and the slide panel is additionally provided with a protractor and transversely slides on the perpendicular panel. The beating parts include a beating rod, a spring and a beating guide rail, and the beating rod moves along the beating guide rail. The invention provides a spring type animal beating method. The spring type small animal beating device can mark different beating forces with angle degrees, by replacing different springs and beating rods, beating of small and medium animals can be realized, injury classification animal beating models can be easily manufactured, and the spring type animal beating type is applicable to researches of biomechanics, injury mechanism and pathology.

Description

technical field [0001] The invention relates to a spring type biological striking device and method. Background technique [0002] Traumatic brain injury (traurnatic brain injury, TBI) is a common clinical emergency in neurosurgery, and it is also one of the major diseases that threaten human life today, especially in patients with severe traumatic brain injury, the mortality rate is very high, about 30%-50% , in clinical research, in order to clarify the mechanism of TBI and the secondary pathophysiological changes after injury, improve the early diagnosis rate, take reasonable and effective treatment measures and rehabilitation methods to reduce the mortality of TBI, and establish an experiment similar to the mechanism of clinical TBI Animal models are of great significance. Since the 1940s, people have applied a variety of methods to replicate closed-platform TBI animal models, which can be roughly divided into falling body impact method, hydraulic shock method, accelera...

AI Technical Summary

Problems solved by technology

Since the 1940s, people have applied a variety of methods to replicate closed-platform TBI animal models, which can be roughly divided into falling body impact method, hydraulic shock method, accelerated load injury method, and controlled cortical injury method according to the different injury methods and mechanisms. Contusion, etc. However, the falling body impact device has the disadvantages that the range of injury is difficult to control, the damage is not easy to quantify finely, and it is not suitable for biomechanical analysis; the hydraulic and accelerated load devices also have problems such as complex instruments, high cost, cumbersome operation, and not easy to promote.
