Description

Technical Field

[0001] The present invention relates to the field of prosthetic repair equipment, and in particular to a personalized repair system for 3D printed prostheses. Background Art

[0002] A prosthesis is an artificial prosthesis specially designed, manufactured and assembled using engineering technology to compensate for the limbs of amputees or those with incomplete limb loss. After the prosthesis is 3D printed, it needs to be polished according to the wearer's leg shape before it can be installed and used. Although the existing polishing device can achieve fixed polishing of the prosthesis, the prosthesis needs to be placed vertically in the polishing device, and dust cannot be effectively isolated during the polishing process.

[0003] According to a prosthesis grinding device disclosed in the existing patent document with publication number CN208866934U, the prosthesis grinding device includes a flat plate, a plurality of nails and a clamping device, the nails pass through the flat plate, a thin rope for connection is provided between the flat plate and the clamping device, a grinding box with an opening on one side is provided at one end of the clamping device, a support frame is provided on the top of the grinding box, a plurality of electric motors are provided on the support frame, and the output end of the electric motor passes through the grinding box. When using this technical solution, it is only necessary to place one end of the nail cap of the nail in the clamping device, so that all the nail tips can protrude a part after being subjected to pressure, thereby facilitating subsequent grinding, avoiding different shapes of the nails after grinding, and further avoiding the uneven surface of the prosthesis after being polished by the nails. With respect to the above technical solution, although this solution completes the grinding of the nails, it is impossible to achieve the wrapping grinding of the prosthesis when grinding the prosthesis, and it is impossible to provide limiting support for both ends of the prosthesis during grinding, which is inconvenient when using it.

[0030] In this embodiment, a mounting hole is provided on the inner wall of the opening 19, and a reset mechanism 30 is fixed inside the mounting hole. The reset mechanism 30 is a reset spring. The reset spring provides an upward thrust for the movable column 21. The limit block 20 quickly returns to its original position under the push of the movable column 21.

[0031] In this embodiment, the collecting assembly 3 includes a filter box 31, the top of the filter box 31 is provided with an air outlet 32, one side of the air outlet 32 ​​is fixedly installed with a handle 33, the side of the filter box 31 is provided with a fixing groove 34, the interior of the fixing groove 34 is movably installed with a baffle 35, the inner wall of the baffle 35 is installed with a limiting mechanism 36, the limiting mechanism 36 is a card bead, the card bead cooperates with the card hole inside the fixing box 1 to realize the limiting fixation of the baffle 35, the inner wall of the fixing groove 34 is fixed with a connecting pipe 40, one end of the connecting pipe 40 cooperates with the baffle 35, the interior of the filter box 31 is fixed with a filter assembly 37, the filter assembly Component 37 is a filter plate, which effectively filters dust in the air. A fixing frame 38 is installed on the side of the filter component 37, and the fixing frame 38 is fixed inside the filter box 31. An exhaust fan 39 is fixedly installed on the fixing frame 38. A lifting mechanism 41 is fixed to the bottom of the filter box 31, and a movable plate 42 is fixed at one end of the lifting mechanism 41. The movable plate 42 is installed at the bottom of the filter box 31. The lifting mechanism 41 is an electric push rod, which pushes the movable plate 42 to move to complete the lifting of the filter box 31 as a whole. The filter box 31 shrinks inside the cavity 2 to avoid the top of the filter box 31 occupying too much space.

[0032] The device provides the required electric energy for the electrical appliances inside the device through an external power supply. When using the device, first hold the prosthesis by hand through the rubber sealing sleeve inside the opening 6 to enter the interior of the fixed box 1, and start the power mechanism through the external switch. The power mechanism drives the active roller 27 to rotate, and the rotation of the active roller 27 drives the grinding belt 18 to rotate on the limiting wheel 28 and the supporting roller 29. While the grinding belt 18 rotates, the grinding belt 18 is limited by the inner wall of the groove 17. When grinding, the face of the grinder looks down from the observation plate 5, which is a glass plate, and the grinding condition of the prosthesis can be observed through the glass plate. Later, on the observation plate 5 After dust adheres to the inner wall, the movable seat 4 is moved upward through the positioning column 8. The downward movement of the movable seat 4 provides a rotating space for the observation plate 5. After the observation plate 5 rotates, the inner wall is cleaned for the next use. When grinding, the two ends of the prosthesis are placed on the limit blocks 20 respectively. In the later stage, the prosthesis presses the limit blocks 20 downward. As the limit blocks 20 descend, the prosthesis contacts the grinding belt 18. The prosthesis applies pressure to the grinding belt 18. When the grinding belt 18 applies pressure, the grinding belt 18 drives the movable rollers 26 on both sides to move toward the middle. When the movable rollers 26 move inward, they squeeze the supporting mechanism 23 through the slider 24, and the supporting mechanism 23 is squeezed into a sliding The movement of the block 24 provides space, so that the grinding belt 18 is deformed inside the opening 19. The deformation allows the grinding belt 18 to wrap and grind prostheses of different shapes. After the grinding is completed, the prosthesis is squeezed out, and the reset mechanism 30 provides an upward thrust for the movable column 21. The movable column 21 moves upward through the limit block 20 to quickly separate the prosthesis from the grinding belt 18 to avoid excessive grinding of the prosthesis by the grinding belt 18. During grinding, the lifting mechanism 41 is started to move the movable plate 42 downward. The reaction force generated by the movable plate 42 pushes the filter box 31 upward, and the top of the filter box 31 is exposed. After being exposed, the baffle 35 is moved upward, and one end of the connecting pipe 40 is opened and connected to the pump The air outlet 10 cooperates with the exhaust fan 39 to generate suction, and the suction force drives the dust from the exhaust port 10 into the interior of the connecting pipe 40, and then enters the interior of the filter box 31 and is filtered by the filter assembly 37. The filtered air is discharged from the air outlet 32, and the baffle 35 is limited by the limiting mechanism 36 and the card hole inside the fixed box 1. Later, when it is necessary to clean the dust inside the filter box 31, the filter box 31 moves upward, and the bottom of the fixed groove 34 cooperates with the bottom of the baffle 35. The fixed groove 34 drives the baffle 35 to be taken out together. While taking it out, the baffle 35 seals one end of the connecting pipe 40 to prevent dust from being discharged from the inside of the connecting pipe 40.
