Abstract

The invention discloses a stationary fixture for pelvis biomechanics experiment. The fixture is connected to a mechanical testing machine by a base. A first anterior superior iliac spine baffle and asecond anterior superior iliac spine baffle of the fixture are respectively connected to a pubic tubercle baffle by a first sacrum stationary jaw and a second sacrum stationary jaw. A top tray of upper margin of pubic bone and a bottom board of lower margin of pubic bone are respectively vertically connected to the pubic tubercle baffle. The first sacrum stationary jaw and the second sacrum stationary jaw are connected to the top tray of upper margin of pubic bone. A sacrum fixing cross slab is fixed on the first sacrum stationary jaw and the second sacrum stationary jaw. A connecting rod is arranged on the lower surface of the top tray of upper margin of pubic bone. A back head of pubic bone is horizontally connected to the connecting rod. The lower head of pubic bone is vertically drilled through the bottom board of lower margin of pubic bone. With the fixture of the invention, the pelvis can be fixed by taking a standing posture to do experiment, and the substance of bone and the structure of pelvic are not destroyed by assembling or detaching the fixture.

Description

technical field [0001] The invention relates to the field of biomechanics, in particular to a fixing fixture for pelvic biomechanics experiments. The scope of application of the present invention is biomechanical experiments using the pelvic standing position as the experimental posture, and the applicable mechanical testing machine is a vertical loading mechanical testing machine. Background technique [0002] At present, there is no special general-purpose pelvic fixation fixture in the field of pelvic biomechanics experiments, and most researchers design the required pelvic fixation fixture by themselves. When different researchers conduct the same experiment, they have to use their own designed fixtures to repeat the experiments done by the predecessors before they can conduct more in-depth research. Otherwise, there is no way to compare the experimental data, resulting in a waste of manpower and material resources. References [1] Wang Qingxian, Zhang Yingze, Pan Jinshe...
