It can precisely reduce fractures according to the surgeon's plan and instructions, thereby reducing the surgeon's workload and improving surgical efficiency and quality.

[0003] Currently, when using fracture reduction surgery robots, nurses push the robot into the operating room and move it to the desired position. They then need to step on the buckles on the moving wheels to limit the wheels and prevent them from moving during use.

[0004] Existing equipment typically has multiple casters installed on its bottom. To secure the equipment, it is necessary to step on the clips on multiple casters, making the process cumbersome and time-consuming, thus limiting the usability of the equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fracture reduction surgical robot. By activating the drive device, two movable plates on the bidirectional screw move along the thread, bringing the two movable plates closer to each other. During the movement of the two movable plates, two rotating rods pull the lifting frame to move. The lifting frame slides within the guide frame, retracting the lifting frame so that the support frame contacts the ground, thus fixing the equipment and improving the convenience of using the equipment.

[0006] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: A fracture reduction surgical robot, comprising a base: a driving device is fixedly installed on one side of the base; a bidirectional screw is rotatably connected to the center of the base; one end of the bidirectional screw is connected to the output end of the driving device; movable plates are connected to the outer surfaces of the bidirectional screw via screens on both sides; rotating rods are rotatably connected to one side of each of the two movable plates; lifting frames are rotatably connected to one end of each of the two rotating rods; guide frames are slidably connected to both sides of each of the two lifting frames; the upper ends of the four guide frames are fixedly connected to the lower end of the base; and support frames are fixedly connected to the four corners of the lower end of the base.

[0007] Preferably, the top of the base is fixedly connected to a guide rail, and the outer surfaces of the guide rails are slidably connected to the inner walls of the two movable plates on both sides.

[0008] Preferably, a reinforcing rib is fixedly connected to one side of the guide frame, and one side of the reinforcing rib is fixedly connected to one side of the base.

[0010] Preferably, a mounting frame is fixedly installed at one end of the robotic arm, and three cylinders are fixedly installed inside the mounting frame. One end of the telescopic rod of each of the three cylinders is fixedly connected to a pull rope. A memory nickel-titanium alloy wire is fixedly connected to the middle of the lower end of the mounting frame. Multiple stabilizing discs are fixedly connected to the outer surface of the memory nickel-titanium alloy wire. One end of the memory nickel-titanium alloy wire is fixedly connected to a surgical instrument mounting platform. One end of each of the three pull ropes is fixedly connected to the upper end of the surgical instrument mounting platform, and the outer surface of each of the three pull ropes is fixedly connected to the inner wall of each of the multiple stabilizing discs.

[0011] Preferably, a protective cover is provided between the mounting frame and the surgical instrument mounting table, and the two ends of the protective cover are fixedly connected to the surgical instrument mounting table and one side of the protective cover, respectively.

[0013] Preferably, both of the lifting frames are fixedly equipped with casters at their lower ends, and a handrail is fixedly connected to one side of the surgical robot body.

[0014] Beneficial Effects: This utility model provides a fracture reduction surgical robot. Compared with the prior art, it has the following beneficial effects: 1. By activating the drive device, two moving plates on the bidirectional screw move along the thread, bringing the two moving plates closer to each other. During the movement of the two moving plates, two rotating rods pull the lifting frame to move. The lifting frame slides in the guide frame, retracting the lifting frame, thereby making the support frame contact the ground, fixing the equipment, and improving the convenience of using the equipment.

[0015] 2. Through the structural design of three sets of cylinders, when one cylinder is opened, the cylinder's extension rod pulls the rope, causing the shape memory nickel-titanium alloy wire to bend in one direction. When all three cylinders are opened at the same time, and the extension lengths of the three cylinders are different, the shape memory nickel-titanium alloy wire can bend without dead angles, so that the angle of the instruments installed on the surgical instrument mounting table is without dead angles. Thus, the fracture reduction surgical robot can be precisely controlled, improving the surgical accuracy.

[0016] 3. Through the structural design of the protective plate and the return spring, when the nurse pushes the fracture reduction surgery robot and accidentally lets go, the fracture reduction surgery robot will move forward due to inertia. When the protective plate hits the wall, the return spring and the buffer rod will absorb the impact force, thereby protecting the equipment. Attached Figure Description

[0027] This application provides a fracture reduction surgery robot, which solves the problem of cumbersome fixation during fracture reduction surgery and makes the device more convenient to use.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1 - Figure 5A fracture reduction surgical robot includes a base 1. A drive device 5 is fixedly installed on one side of the base 1. A bidirectional screw 11 is rotatably connected to the center of the base 1. One end of the bidirectional screw 11 is connected to the output end of the drive device 5. Movable plates 12 are connected to both sides of the outer surface of the bidirectional screw 11. Rotating rods 13 are rotatably connected to one side of each of the two movable plates 12. Lifting frames 10 are rotatably connected to one end of each of the two rotating rods 13. Guide frames 9 are slidably connected to both sides of each of the two lifting frames 10. The upper ends of the four guide frames 9 are fixedly connected to the lower end of the base 1. Support frames 6 are fixedly connected to the four corners of the lower end of the base 1. When the drive device 5 is turned on, the two movable plates 12 on the bidirectional screw 11 move along the thread, so that the two movable plates 12 move closer to each other. During the movement of the two movable plates 12, the two rotating rods 13 pull the lifting frames 10 to move. The lifting frames 10 slide in the guide frames 9 and are stored in the guide frames, so that the support frames 6 contact the ground, thereby fixing the equipment and improving the convenience of using the equipment.

[0030] In a further embodiment, a guide rail 16 is fixedly connected to the top of the base 1. The outer surfaces of the guide rail 16 are slidably connected to the inner walls of the two movable plates 12 respectively. Through the structural design of the guide rail 16, the two movable plates 12 are guided and limited when they move, preventing the movable plates 12 from rotating when they move with the thread of the bidirectional screw 11.

[0031] In a further embodiment, a reinforcing rib 14 is fixedly connected to one side of the guide frame 9, and one side of the reinforcing rib 14 is fixedly connected to one side of the base 1. Through the structural design of the reinforcing rib 14, the connection strength between the guide frame 9 and the base 1 is strengthened.

[0032] In a further embodiment, the upper end of the base 1 is fixedly connected to the surgical robot body 2, and the upper middle part of the surgical robot body 2 is fixedly installed with a robotic arm 3. Through the surgical robot body 2 and the robotic arm 3, the medical instruments on the surgical instrument mounting table 26 can be moved to an approximate position.

[0033] In a further embodiment, a mounting frame 4 is fixedly installed at one end of the robotic arm 3. Three cylinders 21 are fixedly installed inside the mounting frame 4. Each of the three cylinders 21 has a pull rope 22 fixedly connected to one end of its telescopic rod. A memory nickel-titanium alloy wire 23 is fixedly connected to the lower middle part of the mounting frame 4. Multiple stabilizing discs 25 are fixedly connected to the outer surface of the memory nickel-titanium alloy wire 23. A surgical instrument mounting platform 26 is fixedly connected to one end of the memory nickel-titanium alloy wire 23. One end of each of the three pull ropes 22 is fixedly connected to the upper end of the surgical instrument mounting platform 26. The outer surface of the device is fixedly connected to the inner wall of multiple stabilizing discs 25. Through the structural design of three sets of cylinders 21, when one of the cylinders 21 is opened, the telescopic rod of the cylinder 21 pulls the pull rope 22, causing the shape memory nickel-titanium alloy wire 23 to bend in one direction. When the three cylinders 21 are opened at the same time, and the telescopic lengths of the three cylinders 21 are different, the shape memory nickel-titanium alloy wire 23 can bend without dead angles, so that the angle of the instruments installed on the surgical instrument mounting table 26 is without dead angles. Thus, the fracture reduction surgical robot can be precisely controlled, improving the surgical accuracy.

[0034] In a further embodiment, a protective cover 24 is provided between the mounting frame 4 and the surgical instrument mounting table 26. The two ends of the protective cover 24 are fixedly connected to the surgical instrument mounting table 26 and one side of the protective cover 24, respectively. Through the structural design of the protective cover 24, the shape memory nickel-titanium alloy wire 23 and the pull rope 22 can be protected, thereby improving the service life of the equipment. The protective cover 24 is made of rubber.

[0035] In a further embodiment, a telescopic frame 8 is fixedly installed on the other side of the base 1. A protective plate 7 is fixedly connected to one end of the telescopic frame 8. A return spring 20 is provided on one side of the protective plate 7. Mounting plates 18 are fixedly connected to both ends of the return spring 20. A buffer rod 19 is provided between the two mounting plates 18. The two ends of the buffer rod 19 are rotatably connected to one side of the two mounting plates 18 respectively. The other sides of the two mounting plates 18 are fixedly connected to one side of the protective plate 7 and one side of the base 1 respectively. Through the structural design of the protective plate 7 and the return spring 20, when the nurse pushes the fracture reduction surgery robot and accidentally lets go, the fracture reduction surgery robot will move forward due to inertia. When the protective plate 7 hits the wall, the return spring 20 and the buffer rod 19 will absorb the impact force, thereby protecting the equipment.

[0036] In a further embodiment, the lower ends of the two lifting frames 10 are fixedly equipped with moving wheels 15, and a handrail 17 is fixedly connected to one side of the surgical robot body 2. The nurse pushes the device by holding the handrail 17, and the moving wheels 15 move, thereby realizing the movement of the device.

[0037] This utility model provides a surgical robot for fracture reduction, the specific working principle of which is as follows:

[0038] When moving the fracture reduction surgery robot into the operating room, the nurse first pushes the device by holding the handrail 17, pushing the robot to the working area. Then, the drive device 5 is activated, and the two moving plates 12 on the bidirectional screw 11 move along the thread, bringing them closer together. During the movement of the two moving plates 12, the two rotating rods 13 pull the lifting frame 10, which slides within the guide frame 9, retracting the lifting frame 10. This brings the support frame 6 into contact with the ground, fixing the robot in place. After fixing, when using the robot, the surgical robot body 2 and the robotic arm 3 are activated, and the surgical instruments are moved to their approximate positions. Simultaneously, the three cylinders 21 are activated. When the extension and retraction lengths of the three cylinders 21 are different, the memory nickel-titanium alloy wire 23 can bend without any blind spots, ensuring that the angles of the instruments mounted on the surgical instrument mounting table 26 are without any blind spots. This allows for precise control of the fracture reduction surgery robot, improving surgical accuracy.

[0039] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
