Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fixing devices, and particularly to a traditional Chinese medicine physical therapy fixing device for cervical spine bone injuries. Background Art
[0002] Cervical spine bone injuries are usually caused by injuries, accidents, long-term labor and other reasons, resulting in damage or destruction of the cervical spine bone structure. Cervical spine bones include cervical spine bone strain, osteophytes, intervertebral disc prolapse and ligament thickening, resulting in different types of injuries such as compression of the cervical spinal cord, nerve roots or vertebral arteries. For cervical spine bone injuries, surgical treatment or traditional Chinese medicine hot compress physical therapy is usually adopted. However, traditional Chinese medicine hot compress physical therapy usually requires multiple times of hot compress physical therapy on the patient's cervical spine first, and then the use of a physical therapy fixing device for cervical spine bone injuries to fix the patient's cervical spine. This method requires multiple removals of the physical therapy fixing device for cervical spine bone injuries and the performance of hot compress physical therapy work, which may cause the patient's cervical spine to move, thereby causing secondary damage to the cervical spine and being unfavorable for the healing of the patient's cervical spine.
[0003] Therefore, the Chinese patent with the publication number "CN221712397U" discloses "a traditional Chinese medicine physical therapy fixing device for cervical spine bone injuries". Its main structure includes a neck sleeve and two shoulder support cylinders. The lower parts of the outer walls on both sides of the neck sleeve are fixedly connected to the shoulder support cylinders. The front ends of the lower surfaces of the shoulder support cylinders are fixedly connected with first nylon straps. The middle part of the outer wall of one side of the neck sleeve is fixedly connected with a first elastic spandex strap. The middle part of the outer wall of the neck sleeve on the side away from the first elastic spandex strap is fixedly connected with a second elastic spandex strap. For this traditional Chinese medicine physical therapy fixing device for cervical spine bone injuries, through the coordinated use of the first nylon strap and the second nylon strap, the two shoulder support cylinders are fixed under the armpits of the patient, and the pressure of the traditional Chinese medicine physical therapy fixing device on the patient's neck is reduced through the shoulder support cylinders, and the wear of the shoulder support cylinders on the patient's shoulders is reduced through the shoulder pads arranged on the inner walls of the shoulder support cylinders, thereby improving the comfort of the patient's wearing.
[0004] When the above-mentioned traditional Chinese medicine physical therapy fixing device for cervical spine bone injuries fixes the patient's cervical spine, the device is fixed at the patient's mandible and shoulders. The distances between the mandibles and shoulders of different patients are different. Therefore, the applicable population range of the above-mentioned traditional Chinese medicine physical therapy fixing device for cervical spine bone injuries is relatively narrow, and it is easy to occur the phenomenon of secondary injury to the patient due to different support heights. For example, when the support height is too high and the support force is too large, the phenomenon of secondary injury to the patient is likely to occur. Summary of the Invention

[0019] Please refer to Figures 1 to 8 , which is an embodiment of the present invention.
[0020] Please refer to Figure 1 and Figure 2 , a traditional Chinese medicine cervical bone injury physical therapy fixation device, including two bottom fixed base plates 1, two horizontal connection brackets 2 located above the bottom fixed base plates 1, two fixed sleeve bases 3 fixedly installed at one end of the horizontal connection brackets 2, a top fixed base plate 4 installed at the bottom of the fixed sleeve base 3, and a horizontal mounting shaft 5 horizontally installed at the other end of the horizontal connection bracket 2. The bottom fixed base plate 1 is fixedly installed in the working area, and the height of this working area is preferably the same as the height of the patient's shoulder.
[0021] In order to achieve the assembled limit effect on the patient's neck, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, it is necessary to set up an assembled neck limiting mechanism 6, which is internally provided with a rear clamping plate 61 and a front clamping plate 62 that can be stuck around the patient's neck, and a positioning bolt 67 that can fixedly connect the rear clamping plate 61 and the front clamping plate 62. Move the rear clamping plate 61 and the front clamping plate 62 from the outside of the patient's neck towards the center. Finally, the patient's neck is stuck inside the neck sleeve hole 63, and then fixedly installed through the positioning bolt 67. When the rear clamping plate 61 and the front clamping plate 62 are subjected to an upward traction force, the rear clamping plate 61 and the front clamping plate 62 will move upward. Finally, the two buffer pads 64 will abut against the patient's lower jaw and the back of the head, thereby generating an upward traction and positioning effect on the patient's neck.
[0022] For the specific structure of the assembled neck limiting mechanism 6, please refer to Figure 3 and Figure 4 , including a rear clamping plate 61 and a front clamping plate 62. The centers of the rear clamping plate 61 and the front clamping plate 62 form a neck sleeve hole 63. Buffer pads 64 are installed on the upper surfaces of the rear clamping plate 61 and the front clamping plate 62 at the periphery of the neck sleeve hole 63. Annular clamping grooves 65 for clamping the two flat ends of the front clamping plate 62 are provided at the two flat ends of the rear clamping plate 61. Bolt mounting holes 66 are provided in the overlapping area of the rear clamping plate 61 and the front clamping plate 62 at the annular clamping grooves 65. The rear clamping plate 61 and the front clamping plate 62 are fixedly connected by a positioning bolt 67 installed inside the bolt mounting hole 66. Two symmetric rod mounting grooves 68 are provided on the upper surface of the rear clamping plate 61. The buffer pad 64 is made of a textile material with elastic contraction function.
[0023] To achieve telescopic traction with controllable traction force, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, it is necessary to set up two pressure-controlled traction mechanisms 7, which are internally provided with a longitudinal hollow rod 71 that is rotatably installed outside the horizontal mounting shaft 5 and has a hollow interior, a piston plate 79 placed inside the longitudinal hollow rod 71 and capable of moving axially along the longitudinal hollow rod 71, a traction rod 715 for connecting the piston plate 79, the rear clamping plate 61 and the front clamping plate 62, a movable valve plate 710 placed inside the longitudinal hollow rod 71 and capable of controlling the air pressure required when external gas enters the interior of the longitudinal hollow rod 71, and a helical spring 713 that produces an upward elastic damping effect on the movable valve plate 710. Before use, it should be noted that it is necessary to push the traction rod 715, and at the same time pass a wire through the second gas flow hole 714 and the gas-limiting flow chamber 78, and exert a downward force on the movable valve plate 710 to make the movable valve plate 710 move downward, and then make the top of the piston plate 79 located at the top of the lower part movable chamber 74. During the height adjustment process, the horizontal mounting shaft 5 drives the longitudinal hollow rod 71 to move upward. At this time, the traction rod 715 will pull the rear clamping plate 61 and the front clamping plate 62 to move upward. When the two buffer pads 64 abut against the patient's lower jaw and the back of the head, continuing to move the longitudinal hollow rod 71 upward will cause the piston plate 79 to tend to move downward. However, since the space where the upper end face of the piston plate 79 is located is a closed area, under the action of gas negative pressure, it will hinder the downward movement of the piston plate 79. At this time, the gas pressure inside the upper part movable chamber 77 will decrease and exert a downward suction force on the movable valve plate 710. Due to the further increase of the traction force, the air pressure inside the upper part movable chamber 77 will be further reduced. Once the air pressure is greater than the elastic strength of the helical spring 713, the movable valve plate 710 will move downward, and the external gas will flow downward into the lower part movable chamber 74 along the second gas flow hole 714, the gas-limiting flow chamber 78, the movement gap of the movable valve plate 710 and the gas flow groove 712. At this time, the traction force formed by the gas negative pressure will not continue to increase, thus realizing the telescopic traction with controllable traction force. Once it is found that gas enters the second gas flow hole 714, the upward adjustment of the horizontal connecting bracket 2 can be stopped.
[0024] For the specific structure of the pressure-controlled traction mechanism 7, please refer to Figure 5 and Figure 6, including a longitudinal hollow rod 71. A fixed sleeve structure 72 integrated with it is provided at the top of the longitudinal hollow rod 71. A shaft body placement hole 73 sleeving the outer part of the horizontal mounting shaft 5 is provided at the center of the fixed sleeve structure 72. A lower component moving cavity 74 is provided inside the longitudinal hollow rod 71. A rod body perforation 75 communicating the outside space and the bottom end of the lower component moving cavity 74 is provided at the bottom end of the longitudinal hollow rod 71. A first gas flow hole 76 is provided at the top of the longitudinal hollow rod 71 where it is located at the top of the lower component moving cavity 74. An upper component moving cavity 77 is provided at the top of the longitudinal hollow rod 71 where it is located at the top of the first gas flow hole 76. A gas limiting flow cavity 78 is provided at the top of the longitudinal hollow rod 71 where it is located at the top of the upper component moving cavity 77. A second gas flow hole 714 communicating the outside space and the side surface of the gas limiting flow cavity 78 is provided inside the longitudinal hollow rod 71. A piston plate 79 capable of moving axially along the lower component moving cavity 74 is placed inside the longitudinal hollow rod 71 where it is located at the lower component moving cavity 74. A traction rod 715 penetrating the rod body perforation 75 is fixedly installed at the bottom end of the piston plate 79. The bottom end of the traction rod 715 is fixedly installed inside the rod body installation groove 68. An active valve plate 710 capable of moving axially along the upper component moving cavity 77 is placed inside the longitudinal hollow rod 71 where it is located at the upper component moving cavity 77. A plurality of concave gas flow grooves 712 for gas flow are provided on the circumferential surface of the active valve plate 710. An annular gas sealing ring 711 is embedded in the upper end surface of the active valve plate 710. A helical spring 713 in a compressed state is installed at the bottom of the active valve plate 710. The structural radius of the gas limiting flow cavity 78 is the same as that of the first gas flow hole 76, and the structural radii of both are smaller than the structural radii of the upper component moving cavity 77 and the lower component moving cavity 74. The height of the upper end surface of the annular gas sealing ring 711 is higher than that of the upper end surface of the active valve plate 710. The structural radius of the inner circumferential surface of the annular gas sealing ring 711 is larger than the structural radius of the gas limiting flow cavity 78, and the structural radius of the outer circumferential surface of the annular gas sealing ring 711 is smaller than the distance between the gas flow groove 712 and the axis of the active valve plate 710.
[0025] In order to achieve the height adjustment of the horizontal connection bracket 2, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8, it is necessary to set up a threaded longitudinal height support mechanism 8, which is internally provided with a first external threaded rod 86 and a second external threaded rod 87 fixedly connected to the ends of the bottom fixed substrate 1 and the top fixed substrate 4, a longitudinal threaded sleeve 81 that is threadedly connected to the first external threaded rod 86 and the second external threaded rod 87 and can change the distance between the first external threaded rod 86 and the second external threaded rod 87 when rotating, and a polygonal limiting rod 811 inserted at the axis of the first external threaded rod 86 and the second external threaded rod 87 to prevent relative rotation between the first external threaded rod 86 and the second external threaded rod 87. When the longitudinal threaded sleeve 81 is rotated directionally, since the spiral direction of the first thread structure 84 is opposite to that of the second thread structure 85, and during the rotation process, the presence of the polygonal limiting rod 811 makes the first external threaded rod 86 and the second external threaded rod 87 not rotate relative to each other. Therefore, the distance between the first external threaded rod 86 and the second external threaded rod 87 will change, driving the horizontal connecting bracket 2 to move, thereby changing the height of the horizontal connecting bracket 2.
[0026] For the specific structure of the threaded longitudinal height support mechanism 8, please refer to Figure 7 and Figure 8 , including a longitudinal threaded sleeve 81, a first external threaded rod 86 and a second external threaded rod 87. One end of the longitudinal threaded sleeve 81 is provided with a first internal thread cavity 82 with a concave structure, and the other end of the longitudinal threaded sleeve 81 is provided with a second internal thread cavity 83 with a concave structure. The rod body of the first external threaded rod 86 is installed inside the first internal thread cavity 82 through a first thread structure 84, and the rod body of the second external threaded rod 87 is installed inside the second internal thread cavity 83 through a second thread structure 85. The opposite ends of the first external threaded rod 86 and the second external threaded rod 87 are provided with a polygonal limiting cavity 810 with a concave structure. A polygonal limiting rod 811 inserted into the inside of the polygonal limiting cavity 810 is fixedly installed at the center of the longitudinal threaded sleeve 81. One end of the first external threaded rod 86 is provided with a first connecting plate 88 integrally formed with it and fixedly connected to the upper end surface of the bottom fixed substrate 1, and one end of the second external threaded rod 87 is provided with a second connecting plate 89 integrally formed with it and fixedly connected to the bottom end of the top fixed substrate 4. The structural shape of the cross-section of the polygonal limiting cavity 810 is the same as that of the cross-section of the polygonal limiting rod 811, both are polygonal structures, and the structural dimensions of the cross-section of the polygonal limiting cavity 810 match the structural dimensions of the cross-section of the polygonal limiting rod 811. The first thread structure 84 includes an internal thread structure arranged inside the first internal thread cavity 82 and an external thread structure arranged on the rod body of the first external threaded rod 86. The second thread structure 85 includes an internal thread structure arranged inside the second internal thread cavity 83 and an external thread structure arranged on the rod body of the second external threaded rod 87, and the spiral direction of the first thread structure 84 is opposite to that of the second thread structure 85.
[0027] During use, the bottom fixing base plate 1 is fixedly installed in the working area, and the height of this working area is preferably the same as the height of the patient's shoulder. Move the rear clamping plate 61 and the front clamping plate 62 from the outside of the patient's neck towards the center. Finally, make the patient's neck stuck inside the neck sleeve hole 63, and then fixedly install it through the positioning bolt 67. Rotate the longitudinal threaded sleeve 81 directionally. Since the spiral directions of the first thread structure 84 and the second thread structure 85 are opposite, and during the rotation process, due to the existence of the polygonal limiting rod 811, the first outer threaded rod 86 and the second outer threaded rod 87 will not rotate relative to each other. Therefore, the distance between the first outer threaded rod 86 and the second outer threaded rod 87 will change, driving the horizontal connection bracket 2 to move. The horizontal mounting shaft 5 drives the longitudinal hollow rod 71 to move upward. At this time, the traction rod 715 will pull the rear clamping plate 61 and the front clamping plate 62 to move upward. When the two buffer pads 64 abut against the patient's lower jaw and the back of the head, continue to move the longitudinal hollow rod 71 upward, which will cause the piston plate 79 to tend to move downward. However, since the space above the upper end surface of the piston plate 79 is a closed area, under the action of gas negative pressure, it will prevent the piston plate 79 from moving downward. At this time, the gas pressure inside the upper component activity cavity 77 will decrease and generate a downward suction force on the activity valve plate 710. Due to the further increase in the traction force, the air pressure inside the upper component activity cavity 77 will further decrease. Once the air pressure is greater than the elastic strength of the spiral spring 713, the activity valve plate 710 will move downward, and the external gas will flow into the lower component activity cavity 74 along the second gas flow hole 714, the gas limiting flow cavity 78, the movement gap of the activity valve plate 710, and the gas flow groove 712. At this time, the traction force formed by the gas negative pressure will not continue to increase, thus realizing a telescopic traction with controllable traction force. Once it is found that gas enters the second gas flow hole 714, the upward adjustment of the horizontal connection bracket 2 can be stopped, and finally the two buffer pads 64 will abut against the patient's lower jaw and the back of the head.
