Embodiment 1

[0033] image 3 It is an exploded view of the zero calibration device provided in Embodiment 1 of the present invention provided on the striking head adapter. Figure 4 yes image 3 Sectional view along section line A1A2. Such as image 3 with Figure 4 As shown, the zero calibration device includes a bracket 1 , a lever 2 , a contact 3 , a first conductor 4 , a second conductor 5 and an insulating plate 7 . Bracket 1 supports other components of the zero calibration device. During zero calibration, the zero calibration device can also be locked to the striking head adapter through the bracket 1. The lever 2 is connected to the bracket 1 by a rotating shaft. Both bracket 1 and lever 2 are conductors. Place weights on both ends of lever 2. A first conductor 4 is arranged at the first end of the lever 2, and a contact 3 is arranged at the second end of the lever 2 to form a lever balance. Optionally, the distance from the first conductor 4 to the axis of rotation or the...

Embodiment 2

[0040] In the embodiment of the present invention, the basic structure of the zero calibration device is the same as that of the first embodiment, and the components that are the same as those of the first embodiment continue to use the same symbols as those in the first embodiment, including all the features described in the first embodiment. Let me repeat.

[0041] The percussion device provided by the embodiment of the present invention is as figure 1 , image 3 with Figure 4 As shown, the striker includes a power supply (not shown in the figure), striker body and zero calibration device. The striker body is connected to the power supply, and the zero calibration device is arranged on the striker body. The striker body includes a frame, a strike head and a strike head adapter. The striking head is connected to the rack through the striking head adapter. The striking heads include 1mm striking heads, 2mm striking heads, 3mm striking heads, 4mm striking heads, 5mm strik...

Embodiment 3

[0045] The zero calibration method provided by the embodiment of the present invention uses the percussion device described in the second embodiment to perform the zero calibration. The basic structure of the zero calibration device is the same as that of the first embodiment, and the components that are the same as those in the first embodiment continue to use the same symbols as those in the first embodiment. , including all the features described in Embodiment 1, which will not be repeated here. Such as Figure 8 As shown, the zero calibration method includes:

[0046] Step S801: The contact 3 moves along with the striking head.

[0047] Step S802: When the contact 3 reaches the striking position and receives force, the first conductor 4 and the second conductor 5 are disconnected.

[0048] Step S803: The striking head and the contactor 3 stop moving.

[0049] In the embodiment of the present invention, it is judged whether the striking position is reached by whether the...

Abstract

The invention provides a zero calibration device, comprising: a bracket; a lever connected to the bracket through a rotating shaft; a contact arranged at the second end of the lever; a first conductor arranged at the first end of the lever; The second conductor insulated by the bracket; the bracket and the second conductor are respectively connected to the power supply, and when the contact reaches the strike position and is stressed, the first conductor and the second conductor are disconnected. In the present invention, a lever is arranged on the support, and one end of the lever is provided with a contact for contacting the strike position, and the other end of the lever is provided with a first conductor which forms a lever balance with the contact, and the first conductor contacts the second conductor on the support, forming The electric circuit of the bracket, the lever, the first conductor, the second conductor and the power supply, when the contact reaches the strike position and is stressed, the strike position is positioned by combining the circuit on-off and lever mechanics, avoiding the strike position being covered with tissue fluid The problem of inaccurate calibration ensures the accuracy of establishing animal injury models.

Description

technical field [0001] The invention relates to the technical field of scientific research and experimental equipment, in particular to a zero calibration device, a striker with the same, a zero calibration method, and a strike method. Background technique [0002] Traumatic brain injury and spinal cord injury are the most common diseases in neurosurgery, and are the main causes of disability and death in trauma patients. To study the changes in motor, sensory, and autonomic nerve functions of trauma patients after traumatic brain injury and spinal cord injury, and to study the specific mechanism of various dysfunctions caused by nervous system damage in trauma patients, which is helpful for traumatic brain injury and spinal cord injury. The protection and treatment of injuries can help improve the survival rate and quality of life of trauma patients. Establishing various animal injury models that are easy to observe and apply intervention factors, can be graded, well contr...
