Description

Technical Field

[0001] This application relates to the technical field of animal experiment instruments, in particular to a spinal cord percussion device. Background Art

[0002] Common modeling methods include mechanical spinal cord injury models. When using rats as experimental subjects, the rats are anesthetized with an anesthetic, their back hair is removed, and they are disinfected with iodophor. An incision is made at the vertebra of the spinal cord, such as the T10 segment, to find the corresponding vertebral body. Subsequently, the exposed spinal cord of the rat is excised, and then an object of a certain mass (such as a weight) is dropped from a certain height to directly or indirectly impact the spinal cord. Then, the exuded blood is removed with a cotton swab, and the fascia, muscles, and skin of the rat are sutured layer by layer, and the skin of the rat is disinfected again with iodophor. If it meets the standards after evaluation, the modeling is successful. A percussion device is required during the modeling process, which generally causes damage by dropping a heavy object to impact the spine of the experimental subject. Most animal spinal cord injury models are thoracic segment injury models, and the most common injury segments are T8 - T10, manifested as motor and sensory function disorders of the lower limbs and tail, as well as urination and defecation function disorders. For experimental subjects such as mice or rats, due to the relatively small size of the experimental individuals themselves, the corresponding parts that need to be damaged are relatively precise. Therefore, it is necessary to ensure that the percussion process has a relatively accurate landing point. However, during the experiment, the operator usually needs to first find the specific site on the experimental subject. During the process of cutting the skin of the experimental subject and exposing the spinal cord, due to the bleeding and other reactions of the experimental subject, the specific percussion site becomes relatively blurred. Moreover, the actual percussion device during operation also needs to be manually aligned with the specific part of the experimental subject. This makes it necessary for the operator to adjust the orientation and lift the heavy object to perform the dropping collision during actual operation, and the operation process is relatively cumbersome and the manual visual alignment accuracy is poor. Summary of the Invention

[0003] The purpose of this application is to provide a spinal cord percussion device.

[0004] To achieve the above object, the technical solution adopted in this application is as follows: A spinal cord percussion device includes an adjustment mechanism for adjusting the percussion position and a percussion mechanism. The percussion mechanism includes a lifting part, a percussion part, and a searchlight structure. The percussion part and the searchlight structure are located on the same radial line, and a rotating outer shell is provided on the outside of both of them. A transmission structure is provided between the lifting part and the rotating outer shell. In the initial state, the percussion part is at the bottom and the searchlight structure is at the top. When the lifting part is lifted, the rotating outer shell rotates 180° through the transmission structure, so that the percussion part and the searchlight structure rotate and exchange their upper and lower positions. Then, the searchlight structure opens downward to mark the actual percussion position, and returns to its original position when the lifting part is released. During the process, the percussion part and the searchlight structure return first, and then when the lifting part returns to the lowest position, it acts on the percussion part to transfer kinetic energy, so that the percussion part percusses the spine of the experimental subject.

[0005] As a preference, the searchlight structure includes an irradiation part and a control part. The searchlight structure is movably arranged inside the rotating outer shell. The transmission structure includes two steering parts arranged on both sides of the rotating outer shell, and a winding structure and a spiral spring structure respectively arranged on the two steering parts. The lifting part is connected to the winding structure; when the lifting part is lifted, the winding structure elongates and causes the steering part to rotate, so that the rotating outer shell rotates.

[0006] As a preference, the winding structure includes a wire group, a rotating cylinder, and a wire guiding part arranged on the rotating cylinder. The top of the wire group is connected to the lifting part. When the lifting part is lifted, the wire group is dragged to make the rotating part rotate; the winding structure is also provided with a stretching component. After the stretching component elongates the wire group and rotates the rotating outer shell by 180°, through the deformation of the stretching component, the continuous lifting of the lifting part is ensured, and at the same time, the wire group remains in a taut state to enable the searchlight structure to continuously indicate the position downward.

[0007] As a preference, the stretching component includes an elastic element and a first limiting part. The transmission structure also includes a transmission rod. The elastic element is arranged at the end of the transmission rod, and the elastic deformation coefficient of the elastic element is greater than that of the spiral spring structure. The first limiting part is slidably arranged on the transmission rod and is maintained at a set height under the action of the elastic element. A second limiting part is arranged at the top end of the wire group. When the lifting part starts to rise, the moving amount of the wire group is greater than the deformation amount of the elastic element. Until the wire group is straightened, when the lifting part continues to rise, the elastic element is compressed, and at the same time, the first limiting part abuts against the second limiting part to keep the wire group in a taut state, thereby ensuring the state of the rotating outer shell.

[0008] As a preference, the first limiting part and the second limiting part have a transmission interval in the initial state, and the distance of the transmission interval is greater than or equal to the length of the wire group; when the lifting part rises, the first limiting part starts to act on the second limiting part after rising by the transmission interval, and then when the lifting part continues to rise, the wire group is straightened and finally the elastic element is compressed; when the lifting part resets, the elastic element resets first, then the rotating housing rotates and resets by the spring structure, the wire group recovers, and finally the transmission rod completely resets.

[0009] As a preference, the spinal cord percussion device further includes an experimental table, a sleeve, a height-adjusting rod and a horizontal-adjusting rod. The sleeve is fixedly installed on the horizontal-adjusting rod, the horizontal-adjusting rod is fixedly installed on the height-adjusting rod, and the height-adjusting rod is fixedly installed on the experimental table. The height-adjusting rod and the horizontal-adjusting rod form the adjusting mechanism. The height-adjusting rod is suitable for adjusting the height of the horizontal-adjusting rod and the sleeve, and the horizontal-adjusting rod is suitable for adjusting the initial horizontal position of the sleeve; both sides of the bottom of the sleeve are provided with rotating grooves, and the two rotating parts on both sides of the rotating housing are respectively installed on the two non-opening sides of the bottom of the sleeve. When the rotating housing rotates, it is always within the range of the rotating grooves; the lifting part includes a pull rod slidably arranged in the inner cavity of the sleeve, a pulling block formed at the top of the pull rod, and an indicating part at least partially located outside the sleeve. A second spring is further arranged in the inner cavity of the sleeve, and the second spring enables the lifting part to elastically recover every time it is lifted; the middle part of the percussion part is slidably arranged at the center of the bottom of the rotating housing, a limiting protrusion is formed at the top of the percussion part, and a first spring is arranged between the limiting protrusion and the bottom of the rotating housing. The first spring enables the bottom of the percussion part to extend a certain distance from the bottom of the rotating housing in the initial state; in the initial state, the bottom of the pull rod abuts against the searchlight structure, and the bottom of the searchlight structure abuts against the top of the percussion part. After pulling the pull rod and resetting, elastic collisions occur successively between the pull rod, the searchlight structure and the percussion part to transfer kinetic energy.

[0010] As a preference, an anti-detachment structure is arranged on the inner side of the top of the rotating housing. The anti-detachment structure is inclined towards the inner side of the inner cavity of the rotating housing to form a conical socket. The bottom of the pull rod is set to be conical. In the initial state, the bottom of the pull rod is inserted into the inner cavity at the top of the rotating housing and contacts the searchlight structure.

[0011] As a preference, a conductive structure is provided inside the rotating housing. The positive and negative electrodes of the searchlight structure are respectively arranged on its two end faces. One side of the conductive structure is connected to the searchlight structure, and the other side of the conductive structure is connected to the anti-disengagement structure. When the rotating housing rotates 180° from the initial state, the searchlight structure faces downward and moves to abut against the anti-disengagement structure, so as to form a conductive loop through the conductive structure, thereby automatically turning on the searchlight structure.

[0012] As a preference, the spinal cord percussion device further includes a hovering structure. The hovering structure includes a movable buckle and a positioning member. The movable buckle is arranged on the indicating portion, and the movable buckle is adapted to adjust the locking state of the indicating portion to be fixed at the hovering position; the movable buckle includes a movable bolt, and the positioning member is arranged as a positioning groove on the outer side of the sleeve. After the lifting portion finishes lifting, insert the bolt into the positioning groove of the sleeve at the corresponding position to complete the locking.

[0013] As a preference, the coil spring structure includes a coil spring body and a sleeved housing. The sleeved housing is arranged on the outer peripheral side of the end of the steering portion. The two ends of the coil spring body are respectively connected to the end of the rotating portion and the sleeved housing. The sleeved housing is fixedly installed and cannot rotate after installation. When the rotating portion rotates, it drives the coil spring body to rotate and deform, and the sleeved housing remains fixed.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows:

[0015] (1) During the normal process of lifting the percussion mechanism, the rotating housing can be automatically rotated and reversed, so that the searchlight structure faces downward during the lifting process and illuminates and displays the final landing point of the percussion mechanism, so that the operator can accurately obtain the actual percussion position, thus ensuring the accuracy of the actual percussion position; after the lifting is completed, when the lifting portion resets, the percussion portion descends at a certain speed and finally collides with the percussion portion, so as to transfer kinetic energy, and then percussion is performed on the accurate position of the experimental object, which can ensure the accuracy and consistency of the experimental data and provide a reliable experimental tool for spinal cord injury research.

[0016] (2) When manually lifting the lifting portion, the rotating housing can be automatically rotated 180° through the transmission structure, so that the searchlight structure can automatically emit light downward for position indication. During the process of the lifting portion resetting, the rotating housing will first reset, and then when the lifting portion is completely reset, it directly or indirectly acts on the percussion portion, so as to transfer kinetic energy. Then the percussion portion collides with the experimental part of the experimental object, which can avoid the searchlight structure itself contacting the experimental object, thereby preventing dirt.

[0035] Embodiment:

[0036] Refer to Figures 1 to 13, in this embodiment, a spinal cord percussion device is proposed, which includes an adjustment mechanism for adjusting the percussion position and a percussion mechanism. The percussion mechanism includes a lifting part, a percussion part 12 and a searchlight structure 11. The percussion part 12 and the searchlight structure 11 are located on the same radial line, and a rotating outer shell 5 is arranged on the outside of the two. A transmission structure 10 is arranged between the lifting part and the rotating outer shell 5. In the initial state, the percussion part 12 is at the bottom and the searchlight structure 11 is at the top. When the lifting part is lifted, the rotating outer shell 5 is rotated 180° through the transmission structure 10, so that the percussion part 12 and the searchlight structure 11 rotate and exchange their upper and lower positions. Then, the searchlight structure 11 is opened downward to mark the actual percussion position, and it returns to the original position when the lifting part is released. During the process, the percussion part 12 and the searchlight structure 11 return to the original position first, and then when the lifting part returns to the lowest position, it acts on the percussion part 12 and conducts kinetic energy transfer, so that the percussion part 12 percusses the spine of the experimental object. Through the normal process of lifting the percussion mechanism, the rotating outer shell 5 can automatically rotate and change direction, so that the searchlight structure 11 faces downward during the lifting process and illuminates the final landing point of the percussion mechanism, so that the operator can accurately obtain the actual percussion position, thus ensuring the accuracy of the actual percussion position; after the lifting is completed, when the lifting part returns to the original position, the percussion part 12 descends at a certain speed and finally collides with the percussion part 12, so as to conduct kinetic energy transfer, and then percuss the accurate position of the experimental object, which can ensure the accuracy and consistency of the experimental data and provide a reliable experimental tool for spinal cord injury research.

[0037] Actually, it is also feasible to set the middle part of the percussion part 12 as a lens and directly set a light source inside the percussion part 12. However, the bottom of the percussion part 12 usually comes into direct contact with the bones of the experimental object, which is easy to contaminate the blood of the experimental object, etc., and it is also easy to collide with the bones of the experimental object, resulting in scratching or damage of the percussion part 12. When the lens comes into contact with the blood, if it is not cleaned in time, the blood is likely to coagulate, making it difficult to clean the lens again. Therefore, directly setting a lens in the percussion part 12 is not an optimal solution. Therefore, the searchlight structure 11 of this application is independently set. In order to ensure the accuracy of the indication of the searchlight structure 11, a rotating outer shell 5 is set. The rotating outer shell 5 is Figure 1 shown as a cylindrical shell, which ensures that the actual projections of the searchlight structure 11 and the percussion part 12 downward can coincide, so as to ensure that the light of the searchlight structure 11 can accurately irradiate the percussion point. Therefore, during actual operation, when manually lifting the lifting part, the rotating outer shell 5 can be automatically rotated 180° through the transmission structure 10, so that the searchlight structure 11 can automatically emit light downward for position indication. During the process of the lifting part returning to the original position, the rotating outer shell 5 will first return to the original position, and then when the lifting part is completely restored to the original position, it directly or indirectly acts on the percussion part 12, so as to conduct kinetic energy transfer. Then, the percussion part 12 impacts the experimental part of the experimental object, which can prevent the searchlight structure 11 itself from contacting the experimental object, thus preventing contamination.

[0038] It is worth mentioning that it is impossible to perform position calibration only when starting to strike during the model establishment. After exposing the spinal cord of the experimental subject, the position of the striking device is calibrated first. The specific operation is to fix the experimental subject in a suitable position with the fixing component 7, then gently lift the lifting part, let the searchlight structure 11 irradiate and simultaneously adjust the position in real time through the adjustment structure until the light of the searchlight structure 11 is accurately aligned with the predetermined striking point. After ensuring that the initial position is correct, fix the adjustment structure so that the striking part 12 is aligned with the striking site in the vertical direction. At this time, adjust the initial position of the striking part 12 up and down so that the striking part 12 just touches the striking site on the body of the experimental subject, and then fix the overall position of the striking mechanism at this time. Subsequently, the lifting part can be manually lifted to the set height as needed, and it can be observed whether the light at the bottom of the searchlight structure 11 is still accurately aligned with the predetermined striking point. After confirmation, let the lifting part reset, so that the striking part 12 collides with the striking site. Since the striking site of the experimental subject is obtained through processes such as incision and resection, if the position of the striking part 12 is directly adjusted to align it with the striking site, the bottom of the striking part 12 will inevitably touch the uneven body surface of the experimental subject and the surface of the exposed position, which may act on the skin at the exposed position and cause the incised skin to turn back to the exposed position. As a result, the skin needs to be reopened later, which is likely to cause contamination and secondary injury. Therefore, it is not recommended to align the positions in this way.

[0039] Preferably, the searchlight structure 11 includes an irradiation part and a control part. The control part includes specific circuit structures such as circuits and batteries, and no excessive limitations are made. The searchlight structure 11 is preferably movably arranged inside the rotating housing 5. The transmission structure 10 includes two steering parts arranged on both sides of the rotating housing 5 and a winding structure 14 and a spring structure respectively arranged on the two steering parts. The lifting part is connected to the winding structure 14. When the lifting part is lifted, the winding structure 14 is stretched and the steering part rotates, so that the rotating housing 5 rotates. The irradiation part is the actual light-emitting component, which can be set as a spotlight, a low-power laser lamp, etc. It is necessary to ensure that the light has a certain focusing effect at a certain distance, and some light-focusing elements can be added, such as a conical light-focusing cover, etc. It is necessary to ensure that after it emits light, it irradiates vertically downward to the specific experimental location with obvious marks.

[0040] Of course, the above searchlight structure 11 can also be fixedly arranged with the striking part 12. In this way, the searchlight structure 11 and the striking part 12 can be regarded as a whole, and kinetic energy is transferred to this whole when the pull rod 3 descends and collides with the searchlight structure 11 and the striking part 12.

[0041] It is worth mentioning that in this specification, "kinetic energy transfer" mainly refers to the energy transfer when the pull rod 3 collides with the searchlight structure 11 and the knocking part 12. The moving pull rod 3 stops moving after the collision, and at the same time, the searchlight structure 11 and the knocking part 12 transfer the energy to the experimental object, thus completing the "kinetic energy transfer".

[0042] Among them, the coil spring structure is used to keep the rotating outer shell 5 vertical in the initial state and make the knocking part 12 stay below the searchlight structure 11. At the same time, the coil spring structure also needs to provide a restoring force for the winding structure 14 to ensure accurate reset each time. The winding structure 14 is to make the lifting part be able to straighten the wire group 23 when lifting the lifting part, and at the same time make the rotating part 17 rotate. When the wire group 23 is completely straightened, the rotating part 17 just rotates half a turn, so as to ensure the vertical state of the rotating outer shell 5 and ensure that the light of the searchlight structure 11 always accurately aims at the predetermined knocking point.

[0043] Refer to Figure 3 and Figure 7 , Figure 3 The general position of the winding structure 14 is marked. The winding structure 14 includes a wire group 23, a rotating cylinder 15 and a wire guiding part arranged on the rotating cylinder 15. The top of the wire group 23 is connected to the lifting part. When lifting the lifting part, the wire group 23 is dragged to make the rotating part 17 rotate. Since the rotating part 17 actually only rotates half a turn when the wire group 23 is straightened, and actually due to the small diameter of the rotating part 17 itself, the actual length of the wire group 23 may be short, resulting in too short a lifting distance of the lifting part. To avoid this problem, through the setting of the wire guiding part on the surface of the rotating part 17, the winding path of the wire group 23 is set to be inclined, or the outer diameter of the rotating part 17 at this place is appropriately increased.

[0044] Obviously, controlling the rotating outer shell 5 to rotate only 180° during the process is mainly achieved through the wire group 23. Of course, a limiting part can also be set on the inner wall of the sleeve 4, and through the setting of the limiting part, the rotating part 17 is directly restricted from rotating 180° and then abutting, so as to prevent it from rotating excessively.

[0045] Figure 3 and Figure 7 Neither shows the wire guiding part. In fact, the wire guiding part can be a wire groove for controlling the winding direction of the wire group, or a thickened outer shell of the rotating cylinder 15, and its purpose is to extend the wire group 23 as much as possible on the basis of winding half a turn (180°) around the rotating cylinder 15.

[0046] The winding structure 14 rotates the rotating part 17 and the rotating outer shell 5 integrally by pulling the wire group 23 or winding. In fact, the outer diameter of the rotating cylinder 15 and the actual path of the wire part determine the distance by which the wire group 23 is stretched when the rotating outer shell 5 rotates 180°. This distance corresponds to the actual stretching length of the stretching part. Therefore, when the outer diameter of the rotating cylinder 15 and the actual path of the wire part are sufficient to withstand the impact strength of the experiment, it can be used normally. In fact, due to the limitation of the internal space, the outer diameter of the rotating cylinder 15 and the actual path of the wire part may not be sufficient to stretch the stretching part to a sufficient height. Therefore, the winding structure 14 of this embodiment is also provided with a stretching component. After the stretching component stretches the wire group 23 and rotates the rotating outer shell 5 by 180°, the stretching of the stretching part is ensured through the deformation of the stretching component. At the same time, the wire group 23 remains in a taut state to keep the searchlight structure 11 continuously facing down for positioning. After setting the stretching component, there is no need to consider too much the outer diameter of the rotating cylinder 15 and the actual path of the wire part. The actual path of the wire part can be set for the purpose of facilitating the winding of the wire group 23. Correspondingly, after setting the stretching component, obviously as long as it is ensured that the stretching part stretches at least the distance that allows the rotating outer shell 5 to rotate 180°, and then it can be continuously stretched by a set distance as needed, so as to meet the experimental requirements of selecting different knocking intensities for different experimental objects or experimental purposes.

[0047] The stretching component includes an elastic element 20 and a first limiting part 21. The transmission structure 10 further includes a transmission rod 18. The elastic element 20 is arranged at the end of the transmission rod 18, and the elastic deformation coefficient of the elastic element 20 is greater than that of the spring structure. The first limiting part 21 is obviously slidably arranged on the transmission rod 18 and is kept at a certain height under the action of the elastic element 20. A second limiting part 19 is arranged at the top of the wire group 23. When the stretching part starts to rise, the moving amount of the wire group 23 is greater than the deformation amount of the elastic element 20. Until the wire group 23 is straightened, when the stretching part continues to rise, the elastic element 20 is compressed, and at the same time, the first limiting part 21 abuts against the second limiting part 19 to keep the wire group 23 in a taut state, thereby ensuring that the rotating outer shell 5 maintains its state. The reason for the larger elastic deformation coefficient of the elastic element 20 is to ensure that the wire group 23 can be completely straightened first, and then the elastic element 20 deforms. Of course, during the straightening process of the wire group 23, the elastic element 20 will also undergo some deformation under force, but the deformation amount will be much smaller.

[0048] The first limiting part 21 and the second limiting part 19 have a transmission interval 26 in the initial state, and the distance of the transmission interval 26 is greater than or equal to the length of the wire group 23. Refer to Figure 7 and Figure 9In (h), the position of the transmission interval 26 is marked; when the lifting part rises, the first limiting part 21 starts to act on the second limiting part 19 after rising by the transmission interval 26. Subsequently, when the lifting part continues to rise, the wire group 23 is straightened and finally the elastic element 20 is compressed; when the lifting part resets, the elastic element 20 resets first, then the rotating housing 5 is rotationally reset by the reset of the spiral spring structure, the wire group 23 recovers, and finally the transmission rod 18 is completely reset.

[0049] Refer to Figure 5 、 Figure 6 , Figure 6 For the initial states of the first limiting part 21, the second limiting part 19, the transmission rod 18, the elastic element 20 and the wire group 23 in the initial state; a prolonging rod 24 is arranged at the bottom of the second limiting part 19, and the bottom of the prolonging rod 24 is connected to the wire group 23. When the transmission rod 18 at the first limiting part 21 starts to be lifted, the first limiting part 21 slides on the prolonging rod 24 and does not act on the second limiting part 19, nor does it act on the wire group 23. Therefore, at this time, the rotating housing 5 does not rotate. At this time, reference can be made to Figure 8 In (a), until after being lifted by a certain length, the top of the first limiting part 21 starts to act on the bottom of the second limiting part 19. Reference can be made to Figure 8 In (b). At this time, when the transmission rod 18 continues to be lifted, the wire group 23 is tightened and pulled upwards, so the rotating housing 5 starts to rotate. Of course, at this time, the elastic element 20 also starts to deform, but the amount of deformation is small. Until the rotating housing 5 rotates 180°, the wire group 23 is completely pulled out and tightened. Refer to Figure 8 In (c). At this time, when the transmission rod 18 continues to be lifted, the elastic element 20 deforms. Refer to Figure 8 In (d); in the return stage of the transmission rod 18, it is actually similar to the reverse process of the lifting stage. At the beginning of the recovery, the elastic element 20 gradually recovers. At this time, actually the moving distance of the first limiting part 21 is small or it does not move. Refer to Figure 9 In (e) and (f). When the elastic element 20 resets, the height of the first limiting part 21 gradually starts to decrease. In this process, correspondingly, the second limiting part 19 also starts to descend (so at this time the spiral spring structure starts to reset to make the rotating housing 5 reset). Refer to Figure 9 In (g). When the second limiting part 19 and the wire group 23 are completely reset, the transmission rod 18 has not completely returned to the initial position, that is, before the transmission rod 18 continues to return to the initial position, the rotating housing 5 has completed the reset. Subsequently, after a period of time, the transmission rod 18 returns to the initial position. Refer to Figure 9 In (h). Therefore, during actual use, before the knocking starts, the rotating housing 5 can return to the normal state, so that when the bottom of the pull rod 3 descends, it can collide with the searchlight structure 11 and be transmitted to the knocking part 12 to act on the experimental object.

[0050] The provided extension rod 24 is actually to ensure that the pull rod 3 has sufficient pulling stroke. At the same time, it can also ensure that during the reset process of the pull rod 3, the rotating housing 5 has enough time to reset, and it does not affect the kinetic energy transfer of the pull rod 3 to the subsequent searchlight structure 11 and the knocking part 12. Therefore, when using the pull rod 3 to lift for indicating the position of the searchlight structure 11, it is recommended to pull the pull rod 3 to a relatively high height.

[0051] As Figure 1 shown, this spinal cord knocking device further includes an experimental bench 6, a sleeve 4, a height-adjusting rod 1, and a horizontal-adjusting rod 2. The sleeve 4 is fixedly installed on the horizontal-adjusting rod 2, the horizontal-adjusting rod 2 is fixedly installed on the height-adjusting rod 1, and the height-adjusting rod 1 is fixedly installed on the experimental bench 6. The height-adjusting rod 1 and the horizontal-adjusting rod 2 form an adjusting mechanism. The height-adjusting rod 1 is suitable for adjusting the height of the horizontal-adjusting rod 2 and the sleeve 4, and the horizontal-adjusting rod 2 is suitable for adjusting the horizontal position of the sleeve 4 in the initial state. The specific structures of the two can be simply replaced according to actual needs, and their implementation principles are simple, so no more description and limitation are made; both sides of the bottom of the sleeve 4 are provided with rotating grooves, and the two rotating parts 17 on both sides of the rotating housing 5 are respectively installed on the two non-opening sides of the bottom of the sleeve 4. When the rotating housing 5 rotates, it is always within the range of the rotating grooves, and the rotating grooves can refer to Figure 1 the notch formed at the bottom of the sleeve 4; the lifting part includes a pull rod 3 slidably arranged in the inner cavity of the sleeve 4, a pull block 8 formed at the top of the pull rod 3, and an indicating part 32 at least partially located outside the sleeve 4. Actually, scales are usually set on the outer peripheral side of the sleeve 4 for the convenience of controlling the knocking force. The fact that a part of the indicating part 32 is located outside the sleeve 4 can facilitate the operator to observe the lifting height of the lifting part in real time, so as to control the knocking force. A second spring 9 is also arranged in the inner cavity of the sleeve 4. The second spring 9 enables the lifting part to elastically recover after each lift. Of course, after the second spring 9 is set, the knocking force is not simply the conversion of the gravitational potential energy of the lifting part into kinetic energy for knocking. The spring's restoration also needs to be considered, but the deformation of the spring and the corresponding force are in a proportional relationship, so it is also easy to carry out specific control. The middle part of the knocking part 12 is slidably arranged at the center of the bottom of the rotating housing 5. A limiting protrusion is formed at the top of the knocking part 12, and a first spring 25 is arranged between the limiting protrusion and the bottom of the rotating housing 5. The first spring 25 enables the bottom of the knocking part 12 to extend a certain distance from the bottom of the rotating housing 5 in the initial state; in the initial state, the bottom of the pull rod 3 abuts against the searchlight structure 11, and the bottom of the searchlight structure 11 abuts against the top of the knocking part 12. After pulling the pull rod 3 and resetting, the bottom of the pull rod 3 elastically collides with the searchlight structure 11, and then the searchlight structure 11 and the knocking part 12 elastically collide to carry out kinetic energy transfer.

[0052] Since the entire striking part 12 is still installed on the sleeve 4, the position adjustment in this embodiment is actually the position adjustment of the sleeve 4. When adjusting the height adjustment rod 1, it is not actually necessary to accurately adjust it first. First, it is necessary to accurately adjust the initial position of the sleeve 4 through the horizontal adjustment rod 2 so that the sleeve 4 corresponds to the specific experimental striking site of the fixed experimental object in the vertical direction. At this time, fix the horizontal adjustment rod 2, and then adjust the specific height of the sleeve 4 through the height adjustment rod 1.

[0053] Obviously, in this embodiment, the process of the pull rod 3 being pulled up to reset does not directly contact the experimental object. When the pull rod 3 resets, it first contacts the searchlight structure 11, the searchlight structure 11 then contacts the striking part 12, and finally the striking part 12 contacts and collides with the experimental object. Therefore, in order to facilitate the transfer of the kinetic energy of the collision, the bottom of the striking part 12 is preferably not directly restricted from moving. If the striking part 12 is completely fixed, it is very difficult for the striking part 12 to move when transferring kinetic energy after the collision. At this time, the energy generated by the collision is very easy to make the striking part 12 generate internal energy, thereby consuming the energy during striking. For this reason, the first spring 25 is provided. The setting of the first spring 25 makes the striking part 12 extend a certain distance out of the rotating housing 5 in the initial state, but there is no position interference with the rotating housing 5, that is, the striking part 12 can have a certain range of up and down movement, so that it is closer to an elastic collision during the collision, thereby reducing energy loss.

[0054] In order to prevent the movably installed searchlight structure 11 from slipping out of the rotating housing 5, an anti - detachment structure 29 is provided on the inner side of the top of the rotating housing 5. Refer to Figure 12 、 Figure 13 , the anti - detachment structure 29 is inclined towards the inner side of the inner cavity of the rotating housing 5 to form a conical socket. The bottom of the pull rod 3 is set to be conical. In the initial state, the bottom of the pull rod 3 is inserted into the top of the inner cavity of the rotating housing 5 and contacts the searchlight structure 11. When the lifting part is lifted in the initial state, at this time the rotating housing 5 will start to rotate. Therefore, the movable space of the searchlight structure 11 inside the rotating housing 5 cannot be set too large. Otherwise, in the initial condition, the length of the bottom of the pull rod 3 entering the rotating housing 5 is too large, and during the rotation of the rotating housing 5 and the rising of the pull rod 3, the top of the rotating housing 5 may interfere with the pull rod 3. Therefore, setting the bottom of the pull rod 3 to be conical and forming a conical socket inside the anti - detachment structure 29 can avoid interference when the bottom of the pull rod 3 leaves the rotating housing 5.

[0055] Continue to refer to Figure 12 and Figure 13 , a conductive structure is provided inside the rotating housing 5. The positive and negative conductive sheets of the searchlight structure 11 are respectively arranged on its two end faces. Figure 12On one side of the searchlight structure 11 is connected a negative conductive sheet 30, and on one side of the anti - detachment structure 29 is connected a positive conductive sheet 31. One side of the conductive structure is in contact with the searchlight structure 11, and the other side of the conductive structure is in contact with the anti - detachment structure 29. When the outer shell 5 is rotated 180° from the initial state, the searchlight structure 11 moves downward under the action of gravity until it abuts against the anti - detachment structure 29, and a conductive circuit is formed through the conductive structure (that is, the positive conductive sheet 31 and the negative conductive sheet 30 are connected and form a path), thereby automatically turning on the searchlight structure 11. As Figure 13 When the searchlight structure 11 falls, it abuts against the anti - detachment structure 29, and at this time, the positive and negative conductive sheets at the edge are in contact to make the circuit connected. The cooperative setting of the conductive structure and the anti - detachment structure 29 can achieve that after the outer shell 5 is rotated 180° from the initial state, the searchlight structure 11 can be automatically powered on after moving downward, so as to automatically start the position indication, making it more convenient to use. Of course, the searchlight structure 11 can also obtain the rotation state by setting a sensor, and thus a similar automatic switch can also be used in this embodiment.

[0056] Referring to Figure 10 and Figure 11 , the spinal cord percussion device further includes a hovering structure. The hovering structure includes a movable buckle 27 and a positioning member. The movable buckle 27 is arranged on the indicating part 32, and the movable buckle 27 is adapted to adjust the locking state of the indicating part 32 to be fixed at the hovering position. In order to ensure the simplicity of adjusting the sleeve 4 in the experiment, when adjusting the position of the sleeve 4, the lifting part can be manually lifted. At this time, the searchlight structure 11 starts to indicate the position. During the process, the actual position of the sleeve 4 is accurately adjusted by the height - adjusting rod 1 and the horizontal - adjusting rod 2. During this process, it is necessary to keep the continuous illumination of the searchlight structure 11. Therefore, the set hovering structure can ensure that the lifting part is maintained, so that the searchlight structure 11 keeps the illumination state, allowing the operator to free his hands for adjustment operations. As a preferred hovering structure solution, the movable buckle 27 includes a movable pin 28, and the positioning member is set as a plurality of positioning grooves arranged at a certain distance outside the sleeve 4. After the lifting part is lifted, the pin 28 is inserted into the positioning groove at the corresponding position of the sleeve 4 to complete the locking, and the pin is pulled out to unlock.

[0057] Of course, on the one hand, the reset of the pull rod 3 can be carried out by its free - fall motion due to gravity. However, in order to ensure complete reset and sufficient knocking force, it can also be as Figure 2 shown, a spring is arranged at the top of the sleeve 4, and the spring acts on the pull rod 3, so that the bottom of the pull rod 3 penetrates into the outer shell 5 and abuts against the searchlight structure 11 in the initial state.

[0058] As a preferred technical solution of the coil spring structure, the coil spring structure includes a coil spring body 22 and a socket housing 13. The socket housing 13 is disposed on the outer peripheral side of the end of the steering portion. The two ends of the coil spring body 22 are respectively connected to the end of the rotating portion 17 and the socket housing 13. The socket housing 13 is fixedly installed and cannot rotate after installation. When the rotating portion 17 on one side rotates, it drives the coil spring body 22 to rotate and deform, while the socket housing 13 remains fixed. Of course, the coil spring body 22 can not only adopt a coil spring, but also other types such as a snap ring that can be stably reset. The coil spring in this embodiment is only disclosed as a preferred embodiment.

Those skilled in the art should understand that the present application is not limited by the above embodiments. The above embodiments and the description in the specification only illustrate the principles of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and all these changes and improvements fall within the scope of the present application claimed. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
