[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] This utility model provides an anterior reduction device for cervical dislocation, comprising: a reduction rod 1; a push rod 2 slidably connected to the top of the reduction rod 1, and an adjustment groove 3 is provided on one side of the bottom of the push rod 2, and a sliding groove 4 corresponding to the adjustment groove 3 is provided on the top of the reduction rod 1; wherein, an adjustment component is provided in the adjustment groove 3 to move the push rod 2 on the top of the reduction rod 1; a handle 5 is connected to one end of the reduction rod 1 near the adjustment groove 3, the surface of the handle 5 is made of silicone anti-slip texture, and the grip portion is stepped in diameter.

[0020] It should be noted that the reduction rod 1, as the core component of the anterior cervical dislocation reduction device, plays a crucial role in support and positioning. It provides a stable structural framework for the entire device, allowing other components such as the push rod 2 to operate systematically. The push rod 2 is slidably connected to the top of the reduction rod 1, a design that gives the reduction device flexible adjustment capabilities. By sliding the top of the reduction rod 1, the push rod 2 can adjust its relative position according to the specific situation of the cervical dislocation during surgery, thereby better adapting to the different cervical anatomy and degree of dislocation of different patients. The corresponding setting of the adjustment groove 3 and the sliding groove 4, in conjunction with the adjustment components, makes the sliding operation of the push rod 2 more precise and controllable. The handle 5 is connected to the end of the reduction rod 1 near the adjustment groove 3. Its design fully considers the convenience and comfort of the surgeon's operation. The surface uses a silicone anti-slip texture. During surgery, the surgeon's hands may sweat or be stained with blood or other liquids. The anti-slip texture increases the friction between the handle and the hand, preventing the reduction device from slipping and ensuring operational stability. The grip section features a stepped-down diameter design, which conforms to ergonomic principles and better fits the doctor's hand curve, reducing hand muscle fatigue during prolonged operation. This allows doctors to operate the repositioning device more easily and accurately, improving surgical efficiency and quality.

[0021] In an embodiment of this utility model, the adjustment component includes a push block 21 connected to the adjustment groove 3, and the push block 21 is located on the side close to the handle 5. A push plate 22 is connected to the side of the push block 21 away from the handle 5. A push rod 23 is connected to the side of the push plate 22 away from the push block 21. An abutment block 24 is provided in the adjustment groove 3 on the side of the push rod 23 away from the push plate 22. A hole is opened on the abutment block 24 for the push rod 23 to pass through. A spring 25 is sleeved on the outside of the push rod 23. The push block 21 is slidably connected to the sliding groove 4. The bottom of the abutment block 24 is installed in the sliding groove 4. A trigger 6 is rotatably connected to the bottom side of the reset rod 1 near the handle 5. The top of the trigger 6 is located in the sliding groove 4 and abuts against one side of the push block 21.

[0022] It should be noted that: the push block 21, as the component that directly interacts with the trigger 6, slides within the sliding groove 4 when the trigger 6 is pulled, serving as the starting point for force transmission. The push plate 22 and the push rod 23 are connected to the push block 21, converting the displacement of the push block 21 into a thrust on the push rod 2, allowing the push rod 2 to move at the top of the reset rod 1. The abutment block 24 serves as a limit and support, and its opening ensures that the push rod 23 moves along a predetermined path, preventing it from deviating and ensuring the accuracy of the direction of movement of the push rod 2. The spring 25, sleeved on the outside of the push rod 23, is compressed and stores elastic potential energy when the push block 21 moves. When the trigger 6 is released, the spring 25 releases its elastic potential energy, causing the push block 21, push plate 22, and push rod 23 to reset, achieving reversibility of the push rod 2 position adjustment. This allows the doctor to adjust the position of the push rod 2 multiple times according to the actual surgical situation. The connection design between the trigger 6 and the adjustment components greatly improves the ease of operation. The doctor only needs to pull trigger 6 to activate the entire adjustment assembly via push block 21, thereby controlling the movement of the push lever 2, without complicated operating procedures or unnecessary hand movements. This design, similar to a gun trigger, conforms to the human hand's operating habits, allowing the doctor to quickly and accurately adjust the push lever 2, improving surgical efficiency. Simultaneously, the connection between push block 21 and sliding groove 4, and between abutment block 24 and sliding groove 4, ensures the stability of the adjustment assembly during operation, preventing loosening or wobbling during repeated trigger 6 operations.

[0023] In an embodiment of this utility model, a push foot 7 is connected to the bottom of the reset rod 1 at the end away from the handle 5, and a hook foot 8 is connected to the top of the push rod 2 at the end near the push foot 7.

[0024] It should be noted that the push foot 7 and hook foot 8 are designed to specifically contact the dislocated cervical spine. Push foot 7 is connected to the bottom of the reduction rod 1, away from the handle 5, and conforms to the surface of the cervical vertebra. During surgery, it transmits the pushing force applied by the surgeon through the reduction rod, directly acting on the dislocated vertebra and pushing it back into the correct position. Hook foot 8 is connected to the top of the push rod 2, near the push foot 7, and can hook onto adjacent suitable sites, such as the lamina, generating a pulling force through the movement of the push rod. The synergistic effect of these two forces, one pushing and one pulling, compared to a single force application method, more precisely counteracts the dislocation force, improving the success rate of reduction. Because the degree and direction of cervical spine dislocation vary among patients, the push rod 2 can slide on the reduction rod 1, allowing for flexible adjustment of the hook foot 8's position. By adjusting the movement of the push rod 2 using the adjustment component, the relative position and distance between the hook foot 8 and push foot 7 can be changed, thus adapting to various complex cervical spine dislocation situations.

[0025] In an embodiment of this utility model, a guide plate 9 is connected to the bottom of the push rod 2 near the hook foot 8, and a guide block 10 that is slidably connected to the guide plate 9 is provided at the top of the reset rod 1 below the guide plate 9.

[0026] It is important to note that in cervical spine reduction surgery, the direction of movement of the push rod 2 must be precise; otherwise, reduction failure or even damage to surrounding tissues may occur. The sliding connection between the guide plate 9 and the guide block 10 provides a clear guiding path for the movement of the push rod 2. The guide plate 9 is installed at the bottom of the push rod 2 near the hook foot 8, while the guide block 10 is positioned at the corresponding position on the top of the reduction rod 1; the two work together to restrict the push rod 2 to slide only in a specific direction, preventing lateral deviation or wobbling during movement. This allows the surgeon to more accurately control the position of the hook foot 8 and the push foot 7 during the operation, ensuring that the reduction force is applied to the dislocated cervical spine in the correct direction, greatly improving the accuracy and reliability of the reduction operation.

[0027] The working principle of the anterior reduction device for cervical dislocation provided by this utility model is as follows: The doctor first holds the handle 5, which has a silicone anti-slip texture and a stepped, tapered grip. This ergonomic design provides the doctor with a comfortable and stable grip, facilitating subsequent precise operation. Next, the push foot 7 and hook foot 8 of the reduction device are placed near the cervical dislocation site requiring reduction. At this point, the doctor pulls the trigger 6. Since the top of the trigger 6 is located within the sliding groove 4 and abuts against one side of the push block 21, the rotation of the trigger 6 pushes the push block 21 to slide within the sliding groove 4. The push block 21 drives the connected push plate 22 and push rod 23 to move. The push rod 23 passes through the hole on the abutment block 24 and compresses the outer sleeve spring 25, thereby moving the push rod 2 relative to the reduction rod 1. This adjusts the position of the push foot 7 and hook foot 8, ensuring they are in close contact with the cervical dislocation site. Afterward, the trigger 6 is operated again to further adjust the extension length of the push rod 2. During this process, the push foot 7 is connected to the bottom of the reduction rod 1, transmitting the pushing force applied by the doctor to the dislocated vertebra to facilitate vertebral reduction; the hook foot 8 is connected to the top of the push rod 2, generating a pulling force as the push rod 2 moves, hooking onto an adjacent suitable location to assist in reduction. The pushing force of the push foot 7 and the pulling force of the hook foot 8 work together, pushing and pulling precisely to counteract the misalignment force caused by the dislocation. Throughout the movement of the push rod 2, the guide plate 9 is connected to the bottom of the push rod 2 near the hook foot 8, slidingly connected to the guide block 10 at the top of the reduction rod 1. The two work together to provide precise guidance for the movement of the push rod 2, preventing lateral deviation or wobbling, and ensuring that the reduction force is applied to the dislocated cervical vertebrae in the correct direction.
