Description

Technical Field

[0001] This invention relates to the field of spinal cord injury modeling technology, and in particular to a spinal cord injury striker with precise positioning and adjustable striking force. Background Technology

[0002] Spinal cord injury (SCI) is a severe trauma with a high rate of disability, but its treatment remains a major challenge in the medical field. This is because the pathophysiological mechanisms of SCI are highly complex, and researchers' understanding of them is still insufficient and incomplete. Establishing standardized and reliable SCI models is a prerequisite for SCI research and treatment, and is crucial for research progress. Currently, there are various SCI models, among which the heavy object fall impact model is one of the most commonly used animal models of acute spinal cord injury because it more closely resembles the physiological response to injury and the pathophysiology of secondary damage in humans.

[0003] In existing technologies, when simulating spinal cord injury, different levels of spinal cord injury can often only be achieved by adjusting the height of the striking rod. For example, in the invention with publication number CN105853012B, the height adjustment distance of the striking pin movement limiter is limited. When the striking rod is at its highest point, if the striking force is still insufficient, the spinal cord injury striking device needs to be replaced. Furthermore, during the impact simulation, staff need to constantly adjust the striking rod and the position to be struck. Manual adjustment is not only time-consuming, but also prone to errors, leading to deviations in the simulation experiment. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing technologies cannot conduct striking experiments at the same height with different forces, require manual alignment of the striking rod and the position to be struck, and are prone to errors when manually adjusting the position. Therefore, this invention proposes a compact spinal cord injury striking device with precise positioning and adjustable striking force.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A spinal cord injury striker with precise positioning and adjustable striking force includes a worktable, a fixed column fixedly connected to the top of the worktable, a horizontal plate slidably sleeved on the outer wall of the fixed column, and the height of the horizontal plate can be adjusted by a pin and a pin hole on the fixed column, and a frustum is rotatably connected inside the horizontal plate. The top of the workbench is equipped with a positioning component for locating the part of the animal to be struck. The top of the horizontal plate is provided with an incremental component for adjusting different striking forces at the same height; The bottom of the truncated cone is equipped with a striking component for automatically completing the striking task; The horizontal plate is equipped with a drive component for driving the truncated cone to rotate, and the drive component can control the incremental component and the striking component.

[0006] Preferably, the driving assembly includes an infrared emitter fixedly connected to the bottom of the truncated cone, a sliding rod sliding through the truncated cone, and the positions of the sliding rod and the infrared emitter being symmetrical. A spur gear ring located below a horizontal plate is fixedly sleeved on the outer wall of the truncated cone, and a rotating motor is fixedly connected inside the horizontal plate. The output shaft of the rotating motor is fixedly connected to a spur gear that meshes with the spur gear ring.

[0007] Preferably, the incremental component includes a fixing block fixedly connected to the top of the horizontal plate, a trapezoidal block fixedly connected to the side of the fixing block near the frustum, a placement frame fixedly connected to the top of the sliding rod, a sliding rod slidably passing through the top of the placement frame, the bottom end of the sliding rod extending into the placement frame and fixedly connected to a pressure plate, and the pressure plate being used to fix the weights, a second spring fixedly connected to the top of the pressure plate being sleeved on the outer wall of the sliding rod, and the top end of the second spring being fixedly connected to the top inner wall of the placement frame, a round rod fixedly connected to the top inner wall of the pressure plate, and the bottom end of the round rod slidably passing through the placement frame and contacting the top of the trapezoidal block.

[0008] Preferably, the striking assembly includes a base fixedly connected to the bottom of the frustum, a sliding plate slidably passing through the base, a groove on one side of the sliding rod engaging with the sliding plate, a fixing plate fixedly sleeved on the outer wall of the sliding plate, the fixing plate and the base being elastically connected by a tension spring, and one end of the sliding plate passing through the tension spring, the top of the sliding plate having an inclined groove, and a guide rod cooperating with the inclined groove being fixedly connected to the bottom of the horizontal plate.

[0009] Preferably, the positioning component includes a movable groove disposed on the top of the worktable, a movable block slidably connected in the movable groove, a screw fixedly connected in the movable groove and passing through the movable block, a second bevel gear rotatably connected to the side of the movable block near the fixed post, and one end of the screw threaded through the second bevel gear, a drive motor disposed in the movable block, a first bevel gear meshing with the second bevel gear fixedly connected to the output shaft of the drive motor, a turntable rotatably connected to the top of the movable block, and a bevel gear ring meshing with the first bevel gear fixedly connected to the bottom of the turntable.

[0010] Preferably, the top of the turntable is provided with a rotating groove, a U-shaped plate is rotatably connected in the rotating groove, a pressure plate is slidably connected in the U-shaped plate, the top of the pressure plate is elastically connected to the top inner wall of the U-shaped plate by a first spring, and an infrared receiver is fixedly connected to the top of the U-shaped plate.

[0011] Preferably, a hollow block is fixedly connected to the top of the horizontal plate, and a limiting rod is slidably connected inside the hollow block. The top of the limiting rod is elastically connected to the top inner wall of the hollow block by a third spring. A second pressure sensor is fixedly connected to the bottom inner wall of the hollow block, and the top of the second pressure sensor contacts the bottom of the limiting rod. The top of the frustum is provided with two symmetrical arc grooves, and the arc grooves cooperate with the limiting rod.

[0012] Preferably, a striking rod is fixedly connected to the bottom end of the sliding rod, and a first pressure sensor is fixedly embedded in the bottom end of the striking rod. The first pressure sensor can quickly detect the striking force of the striking rod on the animal by striking it with the striking rod.

[0013] Preferably, the top of the workbench is provided with a control center, which is electrically connected to the first pressure sensor, infrared transmitter, rotary motor, second pressure sensor, drive motor and infrared receiver. The control center can control the first pressure sensor, infrared transmitter, rotary motor, second pressure sensor, drive motor and infrared receiver.

[0014] Preferably, an X-ray machine is fixedly connected to one side of the top of the workbench, and a high-speed camera is fixedly connected to the side of the X-ray machine near the turntable. Two telescopic rods are fixedly connected to one side of the top of the workbench, and the top of the telescopic rods is fixedly connected to the bottom of the horizontal plate. When the striking rod strikes the animal, the X-ray machine can capture the distance and time of spinal cord compression when the striking rod strikes the animal, while the high-speed camera can capture the striking trajectory and striking speed when the striking rod strikes the animal's spinal cord, thereby obtaining the specific experimental parameters of the entire striking process.

[0015] Compared with the prior art, the present invention provides a spinal cord injury striker with precise positioning and adjustable striking force, which has the following beneficial effects: 1. The top of the placement frame of this spinal cord injury striker with precise positioning and adjustable striking force has a sliding rod that slides through it. The bottom end of the sliding rod is fixedly connected to a pressure plate. The top inner wall of the pressure plate is fixedly connected to a round rod, and the bottom end of the round rod slides through the placement frame and contacts the top of a trapezoidal block. When the sliding rod drives the placement frame to rotate 180°, the round rod and the trapezoidal block cooperate to push the pressure plate upward, thereby placing the required weight in the placement frame. When the sliding rod drives the placement frame to rotate, the round rod and the trapezoidal block disengage, and the pressure plate fixes the weight. Then, by swapping the positions of the infrared emitter and the sliding rod, the sliding rod is increased in size, which facilitates subsequent striking experiments with different forces at the same height.

[0016] 2. In this spinal cord injury striker with precise positioning and adjustable striking force, a second bevel gear is rotatably connected to the side of the moving block near the fixed column, and one end of the screw is threaded through the second bevel gear. A drive motor is installed inside the moving block, and the output shaft of the drive motor is fixedly connected to a first bevel gear that meshes with the second bevel gear. A bevel gear ring that meshes with the first bevel gear is fixedly connected to the bottom of the turntable. By starting the drive motor, the first bevel gear is driven to rotate, and the first bevel gear can simultaneously drive the second bevel gear and the turntable to rotate. Thus, when the second bevel gear drives the moving block to move slowly, the turntable can rotate relatively quickly, thereby enabling the infrared receiver to receive the infrared rays emitted by the infrared transmitter in a short time, and quickly and accurately completing the positioning of the part to be struck.

[0017] 3. A limiting rod is slidably connected inside the hollow block of this spinal cord injury striker with precise positioning and adjustable striking force. The top of the limiting rod is elastically connected to the inner wall of the top of the hollow block by a third spring. A second pressure sensor is fixedly connected to the inner wall of the bottom of the hollow block. The top of the truncated cone has two symmetrical arc grooves. During the rotation of the truncated cone, the limiting rod can extend into the arc groove under the elastic force of the third spring and exert a squeezing force on the second pressure sensor, thereby timely shutting off the rotating motor and allowing the sliding rod and infrared emitter to switch positions, thus improving the accuracy of the sliding rod's striking point.

[0018] 4. This spinal cord injury striker with precise positioning and adjustable striking force has a slot on one side of the slide rod that engages with a sliding plate. A fixing plate is fixedly sleeved on the outer wall of the sliding plate. The fixing plate and the base are elastically connected by a tension spring. The top of the sliding plate is provided with a guide rod. When the truncated cone rotates 180° to complete the position swap between the infrared emitter and the slide rod, the locking of the slide plate on the slide rod can be released. Thus, when the truncated cone rotates 180°, the slide rod and the striking rod immediately fall downwards to complete the striking experiment. It is simple, convenient, and allows for rapid striking, improving experimental efficiency.

[0019] This invention has a simple structure. By starting a rotating motor to drive a spur gear to rotate, the spur gear drives a truncated cone to rotate 180° through a spur gear ring. This allows for the interchange of the positions of the infrared transmitter and the slide bar while increasing the striking force of the slide bar. Moreover, the rotating cone allows the striking rod to accurately complete the striking experiment without manual operation. In addition, the first bevel gear drives the second bevel gear and the bevel gear ring to rotate, which allows the turntable and the infrared receiver to move while rotating. This enables the infrared receiver to receive the infrared rays emitted by the infrared transmitter and quickly complete the positioning of the striking position. Attached Figure Description

The top of the truncated cone 17 is provided with two symmetrical arc grooves 43, and the arc grooves 43 cooperate with the limiting rod 40. During the rotation of the truncated cone 17, the limiting rod 40 can extend into the arc groove 43 under the elastic force of the third spring 41 and exert a squeezing force on the second pressure sensor 42. This can then shut off the rotating motor 23 in time, allowing the sliding rod 20 and the infrared emitter 19 to switch positions, thereby improving the accuracy of the striking part of the sliding rod 20.

[0026] In this invention, the driving assembly includes an infrared emitter 19 fixedly connected to the bottom of a truncated cone 17 by bolts.

A round rod 31 is fixedly connected to the inner wall by bolts, and the bottom end of the round rod 31 slides through the placement frame 27 and touches the top of the trapezoidal block 26. When the sliding rod 20 drives the placement frame 27 to rotate 180°, the round rod 31 and the trapezoidal block 26 cooperate to push the pressure plate 29 upward, so that the required weight can be placed in the placement frame 27.

When the frustum 17 rotates 180° to complete the position swap between the infrared emitter 19 and the sliding rod 20, the locking of the sliding plate 33 on the sliding rod 20 can be released. Thus, when the frustum 17 rotates 180°, the sliding rod 20 and the striking rod 21 immediately fall downwards to complete the striking experiment.

The elastic force of the first spring 11 allows the pressure plate 10 to clamp the animal strap's striking position. Then, the other parts of the animal are fixed to the turntable 7 by a clamp. The animal fixing clamp is not shown in the existing technical drawings. Start the drive motor 14 to drive the first bevel gear 15 to rotate. The first bevel gear 15 meshes with the second bevel gear 16 and the bevel ring 13. The second bevel gear 16 is threadedly connected to the screw 5. When the first bevel gear 15 drives the second bevel gear 16 to rotate, the second bevel gear 16, under the action of the screw 5, drives the moving block 6 and the turntable 7 to move to the left, and the first bevel gear 15 rotates. Gear 15 drives the second bevel gear 16 to rotate, which in turn drives the bevel ring 13 to rotate. The bevel ring 13 drives the turntable 7 to rotate. As a result, when the second bevel gear 16 drives the moving block 6 to move a short distance, the turntable 7 can rotate multiple times. Therefore, when the moving block 6 moves slowly towards the infrared emitter 19, the turntable 7 can rotate relatively quickly. Then, the infrared emitter 19 is started. When the infrared rays emitted by the infrared emitter 19 are received by the infrared receiver 12, the infrared receiver 12 transmits the signal to the control center (not shown in the control center diagram). The control center shuts down the drive motor 14. At this time, the animal's striking part can be accurately located directly below the infrared emitter 19, pushing the pressure plate 10 upward and squeezing the first spring 1. 1. Release the pressure of the pressure plate 10, rotate the U-shaped plate 9 to retract it into the rotating groove 8, start the rotating motor 23 to drive the spur gear 24 to rotate, the spur gear 24 meshes with the spur ring 18, the spur ring 18 drives the truncated cone 17 to rotate, during the rotation of the truncated cone 17, the inner wall of the arc groove 43 pushes the limiting rod 40 to move upward and squeeze the third spring 41, when the truncated cone 17 rotates 180°, the limiting rod 40 extends into another arc groove 43 under the elastic force of the third spring 41, the bottom of the limiting rod 40 can press the second pressure sensor 42, after the second pressure sensor 42 senses the pressure of the limiting rod 40, it transmits the signal to the control center, the control center shuts down the rotating motor 23, and then the infrared emitter 19 and the striking rod 21 can interact. The position is changed so that the striking rod 21 is directly above the area of ​​the animal to be struck. When the truncated cone 17 rotates the sliding rod 20 and the infrared emitter 19 by 180°, the truncated cone 17 also rotates the sliding plate 33 by 180°. The guide rod 38 can then extend into the inclined groove 37. As the truncated cone 17 rotates the sliding plate 33 by 180°, the sliding plate 33 slides outward in the cooperation of the inclined groove 37 and the guide rod 38. The sliding plate 33 disengages from the slot 34, and the tension spring 36 begins to stretch, releasing the braking force of the sliding plate 33 on the sliding rod 20. The sliding rod 20 and the striking rod 21 fall downward under their own weight, thus enabling the sliding rod 20 to complete the striking experiment on the animal. The first pressure sensor 22 can record the striking force generated when the sliding rod 20 strikes the animal.When it is necessary to test the impact force on the animal at the same height, the rotating motor 23 is started to drive the spur gear 24 to rotate. The spur gear 24 drives the truncated cone 17 to rotate and move a distance through the spur ring 18. After that, the guide rod 38 disengages from the inclined groove 37, pulling the slide rod 20 upward. The sliding plate 33, under the tension of the tension spring 36, extends back into the slot 34 to brake the slide rod 20. When the truncated cone 17 rotates 180°, the truncated cone 17 drives the slide rod 20 and the placement rack 27 to rotate as well. The round rod 31 contacts the trapezoidal block 26. With the cooperation of the trapezoidal block 26, the round rod 31 moves upward and pushes the slide rod 28 and the pressure plate 29 upward. The pressure plate 29 squeezes the second spring 30. At this time, it can prevent the slide rod 20 from moving upward. Weights of equal weight are placed in the placement rack 27. When the frustum 17 rotates 180° again to strike the animal, the round rod 31 disengages from the trapezoidal block 26, and the pressure plate 29 moves downward under the force of the second spring 30, fixing the weights in the placement rack 27. This prevents the weights from moving or detaching from the placement rack 27 during the striking process, which would affect the striking experiment. Furthermore, when the striking rod 21 strikes the animal, the X-ray machine 45 can capture the distance and time of spinal cord compression, while the high-speed camera 46 can capture the striking trajectory and speed of the striking rod 21 striking the animal's spinal cord, thus obtaining the specific experimental parameters of the entire striking process.
