[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0021] like Figure 1 and Figure 2 As shown, a spinal fixation plate includes multiple support units connected end to end in sequence. Each support unit includes two parallel longitudinal rods 11, with a laterally extending support plate 12 between the two longitudinal rods 11. A one-way rotation connection assembly is installed between the ends of the longitudinal rods 11 of adjacent support units. The one-way rotation connection assembly includes a hinge 3 installed between the ends of the two longitudinal rods 11 and located on the rotation side of the longitudinal rods 11. A limiting device is provided between the ends of adjacent longitudinal rods 11 to prevent the longitudinal rods 11 from rotating in the opposite direction.

[0022] Furthermore, the width of the support plate 12 along the direction of the longitudinal rod 11 is less than the length of the longitudinal rod 11.

[0023] Furthermore, the limiting device includes a first wedge-shaped limiting block 41 and a second wedge-shaped limiting block 42. If the first wedge-shaped limiting block 41 is provided at the end of one of the two adjacent longitudinal rods 11, then the second wedge-shaped limiting block 42 that cooperates with the first wedge-shaped limiting block 41 is provided at the end of the adjacent longitudinal rod 11.

[0024] The support unit can only rotate to the hinge 3 side. When the fixed plate is unfolded, the first wedge-shaped limiting block 41 and the second wedge-shaped limiting block 42 of the two adjacent longitudinal bars 11 come into contact and form a limit. In this way, even if the fixed plate is supporting an injured person, the adjacent support units will remain in a straight state due to the existence of the limiting device.

[0025] Furthermore, the first wedge-shaped limiting block 41 is located on the limiting side of the longitudinal rod 11, and the size of the first wedge-shaped limiting block 41 is not smaller than that of the second wedge-shaped limiting block 42. By reasonably setting the sizes of the first wedge-shaped limiting block 41 and the second wedge-shaped limiting block 42, the longitudinal rods 11 of all support units can be in a straight state when unfolded, without any stepped surfaces.

[0026] Furthermore, each of the support units located at both ends is connected to a handle unit 5. A one-way rotating connection assembly is installed between the handle unit 5 and the adjacent support unit. The handle unit 5 includes two handles 5 coaxially arranged with the longitudinal rod 11, and the one-way rotating connection assembly is installed between the handle 5 and the adjacent longitudinal rod 11.

[0027] Furthermore, a hinge 3 is installed at the connection between the handle 5 and the longitudinal rod 11, and between the handle 5 and the longitudinal rod 11. A first wedge-shaped limiting block 41 or a second wedge-shaped limiting block 42 is provided at the end of the handle 5 facing the longitudinal rod 11, and a second wedge-shaped limiting block 42 or a first wedge-shaped limiting block 41 is correspondingly provided at the end of the connected longitudinal rod 11.

[0028] Furthermore, the end of the longitudinal rod 11 is provided with a groove (not shown in the figure) for installing the hinge 3. The hinge 3 is installed in the groove, and the depth of the groove is not less than the thickness of the hinge 3. The hinge 3 is installed in the groove and will not protrude outwards, which is more aesthetically pleasing.

[0029] Furthermore, each of the support plates 12 near the end of the longitudinal rod 11 is provided with an elongated hole 6 for mounting a patient immobilization strap. The elongated holes 6 can be provided in pairs on each support plate 12, or one can be provided every other support plate 12. A suitable patient immobilization strap can be fitted at the required location. The patient immobilization strap is made of flexible material, which can restrain the injured person to the immobilization plate without causing injury.

[0030] When not in use, each support unit can be folded up towards the hinge 3 sides for easy storage or carrying. When rolled up, it can be tied with a strap to prevent it from coming apart during transportation. When in use, the fixing plate can be unfolded. Under the action of the limiting device and the pressure of the injured person on the fixing plate, the entire fixing plate is in a flat plate shape, which facilitates the transport of the injured person.

[0031] The design of the rollable spinal fixation plate solves the inconvenience of traditional spinal fixation plates in terms of use and carrying. Especially in emergency rescue and medical transportation, this fixation plate needs to be lightweight and easy to carry to ensure the stability of the patient during movement and treatment.

[0032] The functional value of a rollable spinal fixation plate lies primarily in its portability. Due to its rollable design, this fixation plate is easier to carry and store, making it particularly suitable for outdoor emergency care and transportation.

[0033] Features of this spinal fixation plate:

[0034] (1) Structural design

[0035] Its lightweight design makes it easy for rescuers to lift, reducing their burden and allowing for more flexible movement and operation in rescue scenarios.

[0036] (2) Sturdiness and load-bearing capacity

[0037] During patient transport, the unfolded fixation plate will not be damaged by the patient's weight, ensuring the stability of the patient's spine and preventing secondary injury.

[0038] Advantages of this spinal fixation plate:

[0039] (1) Protection of the patient. To prevent secondary spinal injury, a sturdy spinal fixation plate can maintain the stability of the spine during transportation, avoiding more serious situations such as displacement of the spinal fracture site or damage to the spinal cord due to shaking, vibration and other factors, thus creating good conditions for subsequent treatment.

[0040] (2) Protection for the user (rescuer). Ease of operation: The spinal fixation plate has an easy-to-operate design, allowing for flexible and convenient operation. This helps rescuers quickly and accurately immobilize patients in emergency situations, reducing the possibility of operational errors and minimizing the time rescuers are exposed to hazardous environments during operation. Reduced workload: Due to its lightweight design, rescuers do not need to bear excessive extra weight, thus reducing workload and allowing them to maintain a better working condition during prolonged rescue operations.

[0041] Spinal fixation devices play a crucial role in rescue efforts, providing fixation, support, and rehabilitation solutions for patients with spinal diseases or injuries. Portable spinal fixation plates, as a new type of spinal fixation device, are convenient to carry and operate, allowing for rapid deployment on patients.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
