Description

Technical Field

[0001] This utility model relates to the field of orthopedic spinal surgery technology, and in particular to a vertebral universal repositioning device. Background Technology

[0002] In orthopedic spinal treatment, it is necessary to surgically remove the diseased or deformed vertebrae. After complete removal, a repositioning and fixation procedure is required. A vertebral universal repositioning device is used to temporarily fix the two vertebrae above and below the patient to facilitate surgical repositioning. However, existing vertebral universal repositioning devices have the following problems: The purpose of using a vertebral universal repositioning device is to locate and fix the vertebral junction. It is usually placed on the operating table for fixation to facilitate repositioning. However, existing vertebral universal repositioning devices are large, inconvenient to store and deploy, and difficult to carry and use. Furthermore, when fixing the vertebrae with the vertebral universal repositioning device, it needs to be easy to adjust the height to suit patients of different body types.

[0003] In existing technology patent CN213129856U, a vertebral universal repositioning device for orthopedic spinal surgery is disclosed. This device uses positioning rods that engage with positioning slots, which are evenly spaced on a support frame. When the support frame slides within the slot, the positioning rods engage with their corresponding slots, fixing the support frame's position and facilitating its deployment and retraction. This makes the device easy to carry and store, space-saving, and convenient to use. An adjusting rod is slidably connected to an adjusting slot via a screw. The adjusting rod has a rectangular structure, and its cross-sectional area is equal to that of the adjusting slot. When the screw is rotated by a knob, the adjusting rod, threaded to the screw, slides up and down within the adjusting slot. By changing the height of the adjusting rod, the height of the clamping rod can be adjusted, making it suitable for patients of different body types.

[0004] However, in the aforementioned prior art patents, the device is not fixed on either side of the bed and is located directly outside the bed, which makes the device prone to shaking during use, which is not conducive to the stable operation of the patient's surgery. Utility Model Content

[0005] The purpose of this utility model is to provide a vertebral universal repositioning device, which aims to solve the technical problem that in the prior art, the device is not fixed on both sides of the bed and is directly located outside the bed, which makes the device prone to shaking during use and is not conducive to the stable operation of the patient's surgery.

[0006] To achieve the above objectives, this utility model employs a vertebral universal repositioning device, comprising two support frames, a repositioning frame, a clamping assembly, a moving assembly, two fixed frames, and two sets of fixing assemblies. The repositioning frame has a retraction groove, and both support frames are movably connected to the repositioning frame and located within the retraction groove. The clamping assembly is disposed below the repositioning frame, and the two fixed frames are respectively fixedly connected to the corresponding support frames. Each fixed frame contains a fixing assembly.

[0007] The moving component includes a disc, a rotating shaft, two first circular shafts, two second circular shafts, two connecting rods, and two limiting blocks.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please see Figures 1-4 This utility model provides a vertebral universal repositioning device, including two support frames 101, a repositioning frame 102, a clamping assembly, a moving assembly, two fixed frames 104, and two sets of fixing assemblies. The repositioning frame 102 has a receiving groove 103. The two support frames 101 are movably connected to the repositioning frame 102 and are located in the receiving groove 103. The clamping assembly is disposed below the repositioning frame 102. The two fixed frames 104 are respectively fixedly connected to the corresponding support frames 101. Each fixed frame 104 is provided with a fixing assembly.

[0021] The moving assembly includes a disc 105, a rotating shaft 106, two first circular shafts 107, two second circular shafts 108, two connecting rods 109, and two limiting blocks 110. The rotating shaft 106 is rotatably disposed above the reset frame 102. The disc 105 is fixedly connected to the rotating shaft 106 and sleeved on the outer wall of the rotating shaft 106. The two first circular shafts 107 are both fixedly connected to the disc 105 and are eccentrically disposed with respect to the disc 105. The reset frame 102 has two through slots 111. The two limiting blocks 110 are respectively fixedly connected to the corresponding support frame 101 and are respectively located in the corresponding through slots 111. The two second circular shafts 108 are respectively fixedly connected to the corresponding limiting blocks 110. The two ends of each connecting rod 109 are rotatably connected to the corresponding first circular shaft 107 and the second circular shaft 108, respectively.

[0022] In this embodiment, during use, the two support frames 101 are first placed on both sides of the hospital bed. Then, the motor on the reset frame 102 is started. The motor drives the rotating shaft 106 to rotate, the rotating shaft 106 drives the disc 105 to rotate, and the disc 105 drives the two first round shafts 107 to rotate. At this time, each connecting rod 109 is pulled by the first round shaft 107, and the two ends of each connecting rod 109 rotate on the first round shaft 107 and the second round shaft 108 respectively. Subsequently, each limiting block 110 will be in the through groove 1 of the reset frame 102. The device moves laterally within the 11th section, causing the support frame 101 to move outward from the receiving slot 103, gradually fixing the support frame 101 to the outside of the bed until the fixing frame 104 on the inner side of the support frame 101 engages with the outside of the bed. The fixing component secures the fixing frame 104 to the outside of the bed. Then, the clamping component below the repositioning frame 102 is activated to clamp and fix the patient's spine. In this way, the device can be fixed on both sides of the bed, adapting to beds of different widths, preventing the device from shaking, and facilitating the stable operation of the patient's surgery.

[0023] Furthermore, the movable component also includes a protective cover 112 and two sets of connectors. The protective cover 112 is fixedly connected to the reset frame 102 and is located above the reset frame 102. Each set of connectors is connected to the protective cover 112 and the reset frame 102 respectively. The connectors include a first magnetic block 113 and a second magnetic block 114. The first magnetic block 113 is fixedly connected to the reset frame 102 and is located on the reset frame 102. The second magnetic block 114 is fixedly connected to the protective cover 112 and is located on the protective cover 112. The second magnetic block 114 and the first magnetic block 113 are magnetically attracted to each other.

[0024] In this embodiment, by setting the protective cover 112, the disc 105, the connecting rod 109 and the limiting block 110 are protected to prevent them from being exposed and damaged. At the same time, the protective cover 112 is fixed to the reset frame 102 by two magnetic blocks, which makes it easy to remove the protective cover 112 and facilitates the subsequent maintenance of the components on the reset frame 102.

[0025] Furthermore, the fixing assembly includes a fixing plate 115, an arc block 116, and a spring 117. The fixing plate 115 is disposed inside the fixing frame 104. The two ends of the spring 117 are fixedly connected to the fixing frame 104 and the fixing plate 115, respectively. The arc block 116 is fixedly connected to the fixing plate 115 and is located on the outer side wall of the fixing plate 115.

[0026] In this embodiment, when the support frame 101 is moved on the reset frame 102, the fixing frame 104 moves along with it, bringing the fixing frame 104 closer to the outside of the bed. The arc block 116 in the fixing frame 104 will first contact the outside of the bed. The force on the arc block 116 will drive the fixing plate 115 to press down the spring 117. Then, the fixing frame 104 continues to move, so that the fixing frame 104 clamps the outside of the bed. At this time, the fixing plate 115 is located below the outside of the bed. The elastic force of the spring 117 is used to fix the fixing frame 104 on the outside of the bed, thereby stabilizing the support frame 101 next to the bed, which is conducive to the stable operation.

[0027] Furthermore, the clamping assembly includes an installation chamber 118, two clamping plates 119, two sleeves 120, a forward and reverse threaded rod 121, and a handwheel 122. The installation chamber 118 is fixedly connected to the reset frame 102 and is located below the installation chamber 118. The two sleeves 120 are movably disposed within the installation chamber 118. Each clamping plate 119 is fixedly connected to the corresponding sleeve 120. Both ends of the forward and reverse threaded rod 121 are rotatably connected to the installation chamber 118 and pass through the two sleeves 120. The forward and reverse threaded rod 121 is threadedly engaged with the two sleeves 120. The handwheel 122 is connected to the forward and reverse threaded rod 121.

[0028] In this embodiment, when fixing the patient's vertebral body, the handwheel 122 is rotated, which drives the positive and negative threaded rod 121 to rotate within the mounting chamber 118. Since both sleeves 120 are threadedly engaged with the positive and negative threaded rod 121, the two sleeves 120 move laterally within the mounting chamber 118. At this time, the two clamping plates 119 move relative to each other until the patient's spinal part is clamped and fixed.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
