[0048] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0049] Reference Figure 1-9An orthopedic nail removal device includes a base 1, and a lifting frame 3 is slidably arranged above the base 1 through two guide rods 2; wherein the lifting frame 3 is vertically arranged, and the two guide rods 2 are arranged in parallel.

[0050] A motor 4 is arranged on the lifting frame 3 , and a screwdriver head 5 or a nail head 6 is detachably arranged on the output end of the motor 4 .

[0051] When in use, the corresponding part of the patient is placed on the base 1, and the position of the steel nail to be removed is made to correspond to the output shaft of the motor 4; according to the specific structure of the steel nail, the corresponding screwdriver head 5 or nail head 6 is selected for installation; then, the nail is removed through this device.

[0052] It can be understood that when the screwdriver head 5 is used to unscrew the steel nail, the motor 4 provides rotational power, and the lifting frame 3 is lifted upward by other power components or manpower; for screws without a screw head slot, the nail head 6 is used to clamp the nail tail and pull it upward.

[0053] It should be noted that the nail head 6 can be implemented using components of the prior art; Figure 6 In one embodiment shown, the lower end of the nail head 6 is an open ring, and the opening and the interior are larger than the diameter of the push rod and smaller than the diameter of the nail tail; the nail is clamped from the opening and pulled out upward.

[0054] It should be noted that for the detachable installation of the screwdriver head 5 or the nail head 6, the existing conventional inner ridge hole sleeve form can be adopted; it should be noted that when installing the nail head 6, an additional locking piece needs to be provided to prevent the nail head 6 from being pulled out; in the specific setting, a rod-shaped body such as a pin shaft or a screw can be used to insert and penetrate the inner ridge hole sleeve and the nail head 6 to lock it.

[0055] In some embodiments, the base 1 includes a bottom plate 11 and a tow pillow 12 disposed on the bottom plate 11 .

[0056] It should be noted that rounded corners are provided at various locations of the drag pillow 12 to avoid scratching the patient.

[0057] Preferably, magic elastic bands 13 are provided on both sides of the drag pillow 12; wherein one end of the magic elastic band 13 is fixed to the side of the drag pillow 12, and the other end is adhered by a magic tape.

[0058] When in use, the base plate 11 can provide stable support to place the patient's body parts in the pillow 12; the pillow 12 is a soft structure, with an outer skin and an inner sponge, latex, etc.; the magic elastic band 13 is used for binding to prevent the patient from making large movements.

[0059] In some embodiments, an anti-slip strip 15 is provided at the lower end of the base 1 to make the placement more stable and reliable.

[0060] In some embodiments, the guide rod 2 and the base 1 are detachably connected, which is more convenient for movement, maintenance, storage, use, etc.

[0061] Specifically, a holder 14 is provided on both sides of the base 1, and an insert plate 21 is provided at the lower end of the guide rod 2; an opening is provided above the holder 14, and when the insert plate 21 is inserted into the holder 14 from one side, the guide rod 2 is inserted into the opening.

[0062] Furthermore, a locking nut 22 is also provided on the guide rod 2 .

[0063] Correspondingly, the guide rod 2 is provided with threads, and fixation is achieved by thread locking; when disassembling, the locking nut 22 is loosened accordingly to take out the guide rod 2.

[0064] Furthermore, a toggle rod 23 is provided on the outer side of the locking nut 22 to facilitate operation.

[0065] In some embodiments, sleeves 7 are rotatably provided at both ends of the lifting frame 3 .

[0066] The thickness of the sleeve 7 is greater than the thickness of the lifting frame 3, making it more stable.

[0067] In some embodiments, the upper portion of the guide rod 2 is provided with an external thread, and the interior of the sleeve 7 is provided with a corresponding internal thread; the lifting frame 3 is provided with a driving assembly 8 for providing power to the sleeve 7 .

[0068] Specifically, the driving assembly 8 includes a stepping motor 81 and a gear 82 respectively arranged at the output end of the stepping motor 81 and the outside of the sleeve 7 .

[0069] When in use, the two gears 82 are meshed, and the overall lifting is controlled by the stepping motor 81 .

[0070] It should be noted that the two stepper motors 81 on both sides need to be controlled synchronously; and their running speeds are preset with corresponding speed values ​​according to the thread and size of the steel nails.

[0071] In some embodiments, a control box 9 is also provided on the lifting frame 3 .

[0072] Among them, a battery is arranged in the control box 9, and a control button 91 is arranged on the control box 9 for quick and efficient operation.

[0073] Preferably, the control box 9 is provided with a display screen 92 which can display the current status, such as lifting height, working mode, operating parameters, etc.

[0074] It should be noted that a control panel is provided in the control box 9 to control the motor 4 and the stepper motor 81; and the system has a series of control parameters preset; when in use, the corresponding parameters are selected according to the patient's nail model to achieve a fully automated, high-precision controlled nail removal process.

[0075] When the utility model is used, after the base support 1 is placed on a stable platform, the corresponding part of the patient is placed in the drag pillow 12 and tied with a magic elastic band 13; thereafter, the corresponding screwdriver head 5 or the nail head 6 is installed according to the model of the patient's steel nails, the screwdriver head 5 is driven by the motor 4, and the lifting frame 3 is driven to be lifted by the stepping motor 81 to remove the nails.

[0076] It is understandable that when the nail head 6 is used, the motor 4 does not need power; at this time, only the stepper motor 81 is required to work.

[0077] In the utility model, a screwdriver head 5 or a nail head 6 can be optionally provided, which is suitable for removing various steel nails; the base 1 is provided with a drag pillow 12 and a magic elastic band 13 to prevent the patient from making large movements and to provide a more stable operating environment; the guide rod 2 is in a detachable form, which is convenient for movement, maintenance, storage, use and other operations; a control box 9 is provided with a control button 91 for quick and efficient operation; a display screen 92 is provided to display the current status for easy control; the system presets control parameters, which are selected according to the steel nail model to achieve a fully automated, high-precision controlled nail removal process.

[0078] In the utility model, the device as a whole is easy to store and move, and has low requirements on the operating environment and operators. The operation can be completed simply, which is conducive to promotion.
