Description
Technical Field
[0001] This utility model relates to the field of auxiliary components for animal experiments, specifically to a spinal cord injury simulation impact device. Background Technology
[0002] Spinal cord injury (SCI) is the most serious complication of spinal cord injury, often leading to severe functional impairment in the limbs below the injured segment. SCI not only causes severe physical and psychological harm to patients but also imposes a huge economic burden on society. However, the treatment of SCI 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. Therefore, establishing standardized and reliable SCI models is a prerequisite for conducting SCI research and treatment, and is of great significance for any progress in the research.
[0003] In the current technology, most of the knowledge humans have about SCI comes from animal spinal cord injury models. Traditional animal spinal cord injury impact experiments usually use the heavy object drop method to impact the dorsal side of the spinal cord. The heavy object drop impact model is closer to human spinal cord injury in terms of physiological response to injury and pathophysiology of secondary injury, and is one of the most commonly used animal models of acute spinal cord injury. However, the current spinal cord injury simulation impact devices are usually not very flexible in their design. First, it is difficult to simulate impact environments of different forces. At the same time, it is not possible to flexibly adjust the impact position. It is often necessary to change the animal's binding position to adjust the spinal impact position, which is very inconvenient to use. Utility Model Content
[0004] The purpose of this invention is to provide a spinal cord injury simulation impact device to solve the above problems. The initial position height of the impact simulation component can be adjusted by sliding the lifting guide sleeve of the height adjustment component vertically along the support column and tightening the clamping stud. At the same time, the impact position of the impact simulation component can be adjusted by adjusting the forward and backward extension of the telescopic rod body. The impact force environment and impact position adjustment method for animal spinal simulation experiments are simple and easy to implement, as detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0013] Preferably, the outer end face of the support column is printed with a vertically set scale, and the outer side of the lifting guide sleeve is provided with an observation opening. An indicator rod is horizontally fixed in the observation opening, and the indicator rod is parallel to the scale line of the scale.
[0014] Preferably, the impact simulation component includes a U-shaped mounting base and an electromagnet body. The rear end face of the U-shaped mounting base is detachably combined with the front end of the telescopic part through the disassembly and assembly assembly. The U-shaped opening of the U-shaped mounting base faces forward, and the upper and lower parts of the U-shaped mounting base are parallel to each other. A guide hole is vertically opened in the lower part of the U-shaped mounting base. The guide hole is a through hole and an impact rod is coaxially inserted through it by a clearance fit. At the same time, a head striker is coaxially fixed at the bottom end of the impact rod. The electromagnet body is fixedly installed on the upper bottom surface of the U-shaped mounting base. The electromagnet body is coaxially aligned with the impact rod, and the top end of the impact rod is magnetically fixed by the bottom surface of the electromagnet body.
[0015] Preferably, the top surface of the U-shaped mounting base is equipped with a controller body for controlling the on and off of the electromagnet body, and the controller body is electrically connected to the electromagnet body. The bottom surface of the U-shaped mounting base is vertically fixed with a guide sleeve at the position outside the guide hole, and the impact rod passes through the guide sleeve coaxially with a clearance fit.
[0016] Preferably, the disassembly and assembly assembly includes a mating seat and a fixing sleeve. The mating seat is fixed longitudinally on the rear end face of the U-shaped mounting seat, and a limiting hole is vertically formed on the top surface of the mating seat. The fixing sleeve is fixed longitudinally in front of the front end of the telescopic part, and a mating groove is formed longitudinally on the front surface of the fixing sleeve. The mating seat is inserted into the mating groove in a longitudinal sliding fit. The top surface of the fixing sleeve has a vertical mounting hole that is perpendicularly connected to the mating groove. The mounting hole and the limiting hole are vertically coaxially aligned. A limiting rod is slidably fitted in the mounting hole along the vertical coaxial axis, and the bottom end of the limiting rod is vertically slidably fitted in the limiting hole. The top end of the limiting rod extends out of the top surface of the fixing sleeve and is coaxially fixed with a pull handle. A spring is coaxially fitted in the portion of the limiting rod between the pull handle and the top surface of the fixing sleeve, and the two ends of the spring are respectively fixedly connected to the pull handle and the top surface of the fixing sleeve.
[0017] Preferably, the mating seat and the mating groove are both rectangular in cross-sectional shape along the horizontal and vertical planes, the mating groove is a blind groove in the longitudinal direction and is opened from front to back, and the rear end of the mating seat is in close contact with the rear end of the mating groove.
[0018] In practical application, the aforementioned spinal cord injury simulation impact device utilizes a height adjustment assembly mounted on the rear top surface of the operating platform. Simultaneously, a longitudinally positioned telescopic rod is mounted on the front of the height adjustment assembly, with the impact simulation component mounted at the front end of the telescopic section of the telescopic rod. The initial height of the impact simulation component can be adjusted by sliding the lifting guide sleeve of the height adjustment assembly vertically along the support column and tightening the clamping stud. Furthermore, the impact position of the impact simulation component can be adjusted by extending and retracting the telescopic rod. This method simplifies and facilitates the simulation of impact forces and positions in animal spinal cord simulation experiments, allowing for easy simulation of impact environments with varying forces and flexible adjustment of the clamping position on the animal's spine. Specifically, the impact simulation component uses an electromagnet energized to magnetically hold the top of the impact rod, suspending the impact pin at the bottom of the impact rod above the animal's spinal cord impact position. The method of de-energizing the electromagnet body releases the magnetic attraction of the impact rod, allowing it to pull down freely. This enables the impact pin at the end to descend and strike the animal's spine, simulating spinal cord injury. The simulation of spinal cord injury is simple and easy to implement, facilitating repeated experiments. Specifically, the assembly / disassembly component uses a longitudinal sliding engagement between the mating seat and the mating groove, and a vertical sliding engagement between the limiting rod and the limiting hole, to detachably fix the impact simulation component at the front end of the telescopic section. Simultaneously, simply pulling the limiting rod out of the limiting hole allows the mating seat to longitudinally disengage from the mating groove, detaching the impact simulation component from the front of the telescopic section. The assembly and disassembly of the impact simulation component at the front of the telescopic section is simple and easy to implement, facilitating quick assembly for spinal cord injury simulation and subsequent maintenance and proper storage after disassembly.
[0019] The beneficial effects are as follows: 1. The present invention has a height adjustment component assembled at the rear of the top surface of the operating table body, and a telescopic rod body arranged longitudinally assembled at the front of the height adjustment component. The front end of the telescopic part of the telescopic rod body is assembled with an impact simulation component. Then, by sliding the lifting guide sleeve of the height adjustment component vertically along the support column and tightening the clamping stud, the initial position height of the impact simulation component can be adjusted. At the same time, by adjusting the telescopic rod body back and forth, the impact position of the impact simulation component can be adjusted. The impact force environment and impact position adjustment method for animal spine simulation experiments are simple and easy to realize. It is convenient to simulate impact environments of different forces and also convenient to flexibly change the clamping position of the animal spine.
[0020] 2. By energizing the electromagnet, the top of the impact rod can be magnetically attracted, thus suspending the impact pin at the bottom of the impact rod above the animal's spinal impact position. Simultaneously, by de-energizing the electromagnet, the magnetic attraction to the impact rod can be released, allowing the impact rod to be pulled down freely. This allows the impact pin to descend and strike the animal's spine, thus simulating spinal cord injury. The simulation of spinal cord injury is simple and easy to implement, facilitating repeated simulation of spinal cord injury impact experiments.
[0021] 3. By using the longitudinal sliding fit between the mating seat and the mating groove of the assembly component and the vertical sliding fit between the limiting rod and the limiting hole, the impact simulation component can be detachably fixed at the front end of the telescopic part. At the same time, by simply pulling the limiting rod out of the limiting hole, the mating seat can be longitudinally disengaged from the mating groove, and the impact simulation component can be removed from the front of the telescopic part. The assembly and disassembly of the impact simulation component at the front of the telescopic part is simple and easy to implement.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0034] See Figures 1-8As shown, this utility model provides a spinal cord injury simulation impact device, including an operating platform body 3 and telescopic rod bodies 4. A height adjustment component 1, capable of vertically raising and lowering and locking, is assembled on the rear top surface of the operating platform body 3. Specifically, the height adjustment component 1 includes a support column 102 and a lifting guide sleeve 105. The support column 102 is vertically fixed on the rear top surface of the operating platform body 3, and the lifting guide sleeve 105 is fitted around the support column 102 in a vertical sliding manner. Several telescopic rod bodies 4 are fixed to the front of the lifting guide sleeve 105, and the rear of the lifting guide sleeve 105... A mating hole 1010 is provided along the longitudinal direction. The mating hole 1010 is a through hole and a clamping stud 108 is inserted longitudinally in a threaded manner. The purpose of this setting is that the initial position height of the impact simulation component 5 can be adjusted by the vertical sliding of the lifting guide sleeve 105 of the height adjustment component 1 along the support column 102 and by tightening the clamping stud 108. At the same time, the impact position of the impact simulation component 5 can be adjusted by the forward and backward extension and retraction adjustment of the telescopic rod body 4. The impact force environment and impact position adjustment method of the animal spine simulation experiment are simple and easy to implement.
[0035] See Figures 1-5 As shown, the front of the height adjustment component 1 is longitudinally assembled with several telescopic rod bodies 4, and the front end of the telescopic part 402 of the telescopic rod body 4 is assembled with an impact simulation component 5, which is used to simulate spinal cord injury impact operation through the impact simulation component 5. Specifically, the impact simulation component 5 includes a U-shaped mounting base 501 and an electromagnet body 507. The rear end face of the U-shaped mounting base 501 is detachably assembled with the front end of the telescopic part 402 through the disassembly and assembly component 2. The U-shaped opening of the U-shaped mounting base 501 is set to face forward, and the upper and lower parts of the U-shaped mounting base 501 are parallel to each other. The lower part of the U-shaped mounting base 501 has a guide hole 503 vertically opened. The guide hole 503 is a through hole and an impact straight rod 505 is coaxially inserted through it by clearance fit. At the same time, the bottom end of the impact straight rod 505 is coaxially fixed. The device includes an end-pointing striker 506 and an electromagnet body 507 fixedly mounted on the upper bottom surface of a U-shaped mounting base 501. The electromagnet body 507 is coaxially aligned with the impact rod 505, and the top of the impact rod 505 is magnetically fixed by the bottom surface of the electromagnet body 507. This arrangement is designed so that when the electromagnet body 507 is energized, it can magnetically hold the top of the impact rod 505, thereby suspending the end-pointing striker 506 at the bottom of the impact rod 505 above the animal's spinal impact position. At the same time, when the electromagnet body 507 is de-energized, it can release the magnetic fixation of the impact rod 505, allowing the impact rod 505 to pull down freely. This allows the end-pointing striker 506 to descend and impact the animal's spine, thus completing the simulated impact operation for spinal cord injury. The simulated impact operation for spinal cord injury is simple and easy to implement.
[0036] See Figures 1-5As shown, a disassembly and assembly assembly 2 is provided between the front end of the telescopic part 402 and the rear end of the impact simulation component 5. The impact simulation component 5 is detachably assembled to the front end of the telescopic part 402 via the disassembly and assembly assembly 2. Specifically, the disassembly and assembly assembly 2 includes a mating seat 208 and a fixing sleeve 203. The mating seat 208 is fixed longitudinally on the rear end face of the U-shaped mounting seat 501, and a limiting hole 206 is vertically formed on the top surface of the mating seat 208. The fixing sleeve 203 is fixed longitudinally in front of the front end of the telescopic part 402, and a mating groove 207 is formed longitudinally on the front surface of the fixing sleeve 203. The mating seat 208 is inserted into the mating groove 207 in a longitudinal sliding fit. The top surface of the fixing sleeve 203 has a vertical mounting hole 205, which is vertically connected to the mating groove 207. The mounting hole 205 and the limiting hole 206 are vertically coaxially aligned. The mounting hole 205 is slidably fitted with a limiting rod 204 along the vertical coaxial direction, and the limiting rod is positioned accordingly. The bottom end of the rod 204 is vertically slidably engaged with the limiting hole 206. The top end of the limiting rod 204 extends out of the top surface of the fixing sleeve 203 and is coaxially fixed with the pull handle 201. The part of the limiting rod 204 located between the pull handle 201 and the top surface of the fixing sleeve 203 is coaxially fitted with a spring 202, and the two ends of the spring 202 are respectively fixedly connected to the pull handle 201 and the top surface of the fixing sleeve 203. The purpose of this arrangement is that by the longitudinal sliding engagement of the mating seat 208 and the mating groove 207 of the disassembly and assembly assembly 2 and the vertical sliding engagement of the limiting rod 204 and the limiting hole 206, the impact simulation assembly 5 can be detachably fixed at the front end of the telescopic part 402. At the same time, by simply pulling the limiting rod 204 out of the limiting hole 206, the mating seat 208 can be longitudinally disengaged from the mating groove 207, and the impact simulation assembly 5 can be detached from the front of the telescopic part 402. The assembly and disassembly of the impact simulation assembly 5 at the front of the telescopic part 402 is simple and easy to implement.
[0037] See Figures 1-8 As shown, the following optimizations were made to the telescopic rod body 4, the operating platform body 3, the height adjustment component 1, the impact simulation component 5, and the disassembly and assembly component 2. Specifically, for the telescopic rod body 4 and the operating platform body 3, the telescopic rod body 4 is a double-section pull-out telescopic rod with a locking screw 401, so that the telescopic rod body 4 can be adjusted by pulling out the telescopic part 402 and tightening the locking screw 401. Optionally, a cushioning material pad 301 is fixedly covered on the front top of the operating platform body 3, so that the animal restraint operation can be performed on the top surface of the pad 301. An animal restraint device (not shown in the figure) is also provided on the top surface of the operating platform body 3 in the area corresponding to the pad 301. The animal restraint device can be multiple restraint straps to fix the animal's limbs. The specific structure of this type of animal restraint device is existing technology and can be set according to actual needs.
[0038] See Figures 1-8As shown, specifically for the height adjustment component 1, both the support column 102 and the lifting guide sleeve 105 have rectangular horizontal cross-sectional shapes. A plug 101 is coaxially mounted on the top of the support column 102. This design facilitates good positioning and guidance when the lifting guide sleeve 105 slides vertically along the support stud, and also prevents the lifting guide sleeve 105 from accidentally detaching from the top of the support column 102 using the plug 101. An elastic pressure block 109 with an outer diameter smaller than the mating hole 1010 is coaxially fixed to the front end of the clamping stud 108. A handle 104 for easy gripping is coaxially fixed to the rear end of the clamping stud 108. This improves the locking stability of the lifting guide sleeve 105 by pressing the elastic pressure block 109 against the surface of the support column 102, and also facilitates rotation of the clamping stud 108 by applying force through the handle 104. Alternatively, a vertically set scale 103 is printed on the outer end face of the support column 102, and an observation opening 107 is opened on the outer side of the lifting guide sleeve 105. An indicator rod 106 is horizontally fixed in the observation opening 107, and the scale line of the indicator rod 106 is parallel to the scale line of the scale 103. With this setting, it is convenient to quantitatively adjust the initial position height of the end striker 506 by referring to the scale 103 with the indicator rod 106, so as to accurately control the free fall stroke of the end striker 506.
[0039] See Figures 1-8 As shown, specifically for the impact simulation component 5 and the disassembly and assembly component 2, the top surface of the U-shaped mounting base 501 is equipped with a controller body 502 for controlling the on and off of the electromagnet body 507, and the controller body 502 is electrically connected to the electromagnet body 507. The bottom surface of the U-shaped mounting base 501 is vertically fixed with a guide sleeve 504 at the position outside the guide hole 503, and the impact rod 505 passes through the guide sleeve 504 coaxially with a clearance fit. With this setting, it is convenient to control the on and off of the electromagnet body 507 by means of the controller body 502, and at the same time, it is convenient to position the impact rod 505 through the guide sleeve 504, so that the top of the impact rod 505 can be accurately attracted by the electromagnet body 507. Preferably, the impact rod 505 is an iron cylindrical rod. Furthermore, both the mating seat 208 and the mating groove 207 have rectangular cross-sectional shapes along their horizontal and vertical planes. The mating groove 207 is a blind groove in the longitudinal direction and is opened from front to back. The rear end of the mating seat 208 is in close contact with the rear end of the mating groove 207. This arrangement firstly facilitates good positioning and guiding design when the mating seat 208 slides longitudinally along the mating groove 207. At the same time, during the process of the mating seat 208 sliding longitudinally along the mating groove 207, when the limiting hole 206 moves longitudinally with the mating seat 208 to be coaxial with the limiting rod 204, a clear indication can be given by the way the rear end of the mating seat 208 is in close contact with the rear end of the mating groove 207.
[0040] With the above structure, in practical use, a height adjustment component 1 is assembled at the rear of the top surface of the operating platform body 3, and a longitudinally arranged telescopic rod body 4 is assembled at the front of the height adjustment component 1. An impact simulation component 5 is assembled at the front end of the telescopic part 402 of the telescopic rod body 4. The initial position height of the impact simulation component 5 can be adjusted by the vertical sliding of the lifting guide sleeve 105 along the support column 102 and by tightening the clamping stud 108. Simultaneously, the telescopic rod body 4 can be extended and retracted to adjust the height. The adjustable mechanism allows for adjustment of the impact position of the impact simulation component 5. This simplifies the adjustment of the impact force and position in animal spine simulation experiments, facilitating the simulation of impact environments with varying forces and allowing for flexible changes to the clamping position on the animal spine. Specifically, the impact simulation component 5 uses an electromagnet 507 that is energized to magnetically hold the top of the impact rod 505, suspending the impact pin 506 at the bottom of the rod above the impact position on the animal spine. Conversely, de-energizing the electromagnet 507... This method releases the magnetic fixation of the impact rod 505, allowing it to pull down freely. This enables the impact pin 506 to descend and strike the animal's spine, simulating spinal cord injury. The simulated impact operation is simple and easy to implement, facilitating repeated experiments. Specifically, regarding the assembly and disassembly of component 2, the longitudinal sliding engagement between the mating seat 208 and the mating groove 207, and the vertical sliding engagement between the limiting rod 204 and the limiting hole 206 of component 2 allow the impact simulation assembly to be assembled... The component 5 is detachably fixed at the front end of the telescopic part 402. At the same time, by simply pulling the limiting rod 204 out of the limiting hole 206, the mating seat 208 can be longitudinally disengaged from the mating groove 207, thereby removing the impact simulation component 5 from the front of the telescopic part 402. The assembly and disassembly of the impact simulation component 5 at the front of the telescopic part 402 is simple and easy to implement. This facilitates the quick assembly of the impact simulation component 5 at the front of the telescopic part 402 for simulated impact operations of spinal cord injury, and also facilitates subsequent inspection, maintenance and proper storage of the impact simulation component 5 after disassembly.
