Impact-wave-based animal bone injury generation device and standardized fracture experiment method

Abstract

The invention discloses an impact-wave-based animal bone injury generation device which is characterized in that the device comprises an annular support (1), a base (2) and four impact-wave gun heads(3) with same structures, the base (2) is connected with the annular support (1), each impact-wave gun head is provided with a cylinder with two flatted sides, outer threads (31) and scale lines (32)are arranged on the surfaces of the cylinders, four rotating disk hollow holes (11) are radially and symmetrically formed in the annular support (1), a rotating disk (12) is arranged in each rotatingdisk hollow hole, inner threads (120) of the rotating disks (12) are connected with outer threads (31) of the impact-wave gun heads (3) in a threaded manner, and the rotating disks (12) can adjust distances of the impact-wave gun heads (3) opposite to a circle center of the annular support (1). The device is high in repeatability and good in stability, and errors between samples can be effectivelyreduced. According to the device, different bone injury models can be acquired by adjusting the power of an impact-wave generation device, and quantitative research is facilitated.

Description

technical field [0001] The invention relates to the technical field of animal experiments, in particular to a shock wave-based animal bone injury generating device and a standardized fracture experiment method. Background technique [0002] Fractures and other bone injuries are common clinical diseases, and it is very important to study bone injuries through animal experiments. Therefore, it is necessary to make animal bone injury samples with uniform standards. Before the present invention, some animal bone injury model instruments generally had problems such as large randomness, low repeatability, low accuracy, and incapable of quantitative research. On the one hand, the traditional bone injury generation device has randomness in the impact site, which leads to sample errors, and on the other hand, it may cause an open wound that is susceptible to infection, which brings greater uncertainty and interferes with the experiment.
