Abstract
The invention discloses a traumatic craniocerebral injury instrument, which relates to the technical field of laboratory equipment and comprises a base plate, a supporting frame, a direction adjusting mechanism and an injury mechanism, wherein first angle scales are arranged on the end surface of the bottom plate; the supporting frame is arranged in the middle of the bottom plates, and a bandage is arranged on the supporting frame; the direction adjusting mechanism comprises a horizontal rotating mechanism, a lifting and lowering mechanism and a vertical rotating mechanism, wherein the horizontal rotating mechanism is arranged on a sliding rail in a sliding mode, the lifting and lowering mechanism is arranged on the horizontal rotating mechanism, and the vertical rotating mechanism is arranged on the lifting and lowering mechanism; and the injury mechanism is arranged on the vertical rotating mechanism. By use of the traumatic craniocerebral injury instrument, an impact angle, the weight of an impact object during impact and the impact speed can be adjusted so as to be favorable for forming a craniocerebral injury model.
Description
technical field [0001] The invention relates to the technical field of laboratory equipment, in particular to a traumatic brain injury instrument. Background technique [0002] Traumatic brain injury (traumatic brain injury, TBI) is a common neurological emergency with high disability and high mortality. The resulting craniocerebral and spinal cord injuries have caused a huge burden on patients, families and society, and have become the focus and difficulty of global medical and health care. Although with the development of surgery and interventional techniques, we have made some progress in the treatment of traumatic brain injury, but the improvement of the prognosis of traumatic brain injury is still not ideal. [0003] Therefore, studying the changes in neurobiochemical and neuropathophysiological aspects after brain injury, and exploring effective brain protection treatment plans will help improve the survival rate and quality of life of patients with traumatic brain in...
