Technical Field
[0001] The present invention relates to the technical field of portal nail positioning, and more particularly to a positioning device for orthopedic portal nails. Background Art
[0002] Portal nails, also known as bone nails or bone fixation nails, are medical devices used to fix bone structures during surgical operations. They are usually made of metal materials and generally have high strength and corrosion resistance characteristics to achieve the purpose of providing stable support after surgery and promoting bone healing.
[0003] Patent Publication No. CN117958945A discloses a positioning device and usage method for orthopedic portal nails, including a lying bed. A restraint structure is slidably connected to the top of the lying bed. A positioning structure and a portal nail fixing structure that cooperate with the positioning structure are slidably connected to both sides of the lying bed in sequence from left to right. A cavity is provided in the inner wall of the lying bed, and a driving structure for providing power to the positioning structure and the portal nail fixing structure is installed inside the cavity. When the A screw rod rotates, it can drive the movable block to move. While the movable plate is moving, it can drive the drilling assembly to move. After the drilling assembly moves to the position where the patient needs to be nailed, drilling is performed. Subsequently, the portal nail fixing structure installs according to the reserved hole drilled by the drilling assembly, thereby reducing the problems of high requirements for medical staff, high risk, and poor accuracy of traditional devices.
[0004] Although the above device realizes the positioning and precise movement of the portal nail to reduce the problem of high requirements for staff operation, in its overall operation steps, since the drilling assembly and the portal nail fixing structure need to be adjusted separately in the front, back, left, and right directions for precise positioning, there is a correspondingly complex operation process, which in turn leads to a low installation efficiency. Finally, in the two independent adjustment processes, there may also be a situation where the drilling position is different from the position of the subsequent portal nail adjustment and positioning, thus unable to ensure the consistency of the position adjustment of the two. Therefore, a positioning device for orthopedic portal nails is proposed here to solve the above problems. Summary of the Invention

After the positioning rods 53 are inserted into the positioning grooves 4, the bottom end of the support plate 31 is locked, improving the stability of the support plate 31 after installation.
[0053] During the actual operation process, when this device is in use, first, the device is powered on. The patient receives treatment on the bed body 1. The support plate 31 in this device can be flexibly disassembled and assembled. Specifically, when operating, rotate the threaded auxiliary rod 52. The threaded auxiliary rod 52 drives the connecting plate 51 to move up and down. The connecting plate 51 drives the positioning rod 53 to move. When the positioning rod 53 moves out of the positioning groove 4, the support plate 31 can be taken out from the placing seat 35 for disassembly. Similarly, when installing, after the bottom end of the support plate 31 is placed in the placing seat 35, control the positioning rod 53 to insert into the positioning groove 4, and then the installation of the support plate 31 is completed. In this way, convenient disassembly and assembly are carried out, improving the flexibility during use. When the bed body 1 does not need to perform surgical treatment tasks, it is convenient to remove the support plate 31 to save space and add convenience for personnel to get on and off the bed body 1;
[0054] A clamping groove 398 is provided on the portal nail body 397. During installation, after inserting the two lifting plates 396 into the two clamping grooves 398, the first motor 387 works and drives the bidirectional threaded rod 386 to rotate. The bidirectional threaded rod 386 drives the movable block 394 to move. The movable block 394 drives the base frame 395 to move. The base frame 395 drives the lifting plate 396 to move. The lifting plate 396 can slide horizontally left and right on the long plate 388. Therefore, the movement of the lifting plate 396 will not affect the long plate 388. When the lifting plate 396 moves to fit inside the clamping groove 398, the installation of the portal nail body 397 is completed. When installing the drill rod 384, after inserting the rectangular block 385 at the top of the drill rod 384 into the rectangular groove 383, screw in the fixing bolt 375 to fix the rectangular block 385 inside the fixing rod 382. Similarly, when disassembly is required, repeating the above opposite operations can achieve the disassembly of the portal nail body 397 and the drill rod 384. Correspondingly, the portal nail body 397 and the drill rod 384 can be quickly disassembled and assembled, with a low operation threshold and can be quickly mastered for operation;
[0055] During use, after the fifth motor 367 operates, it drives the second threaded rod to rotate. The second threaded rod drives the moving block 36 to move. The moving block 36 drives the auxiliary frame 37 to move. The auxiliary frame 37 drives the first electric push rod 39 to move. The first electric push rod 39 drives the U-shaped plate 38 to move. The U-shaped plate 38 drives the connecting rod 391 to move. The connecting rod 391 drives the rotating platform 392 to move horizontally. After the fourth motor 365 operates, it drives the first threaded rod to rotate. The first threaded rod drives the control board 32 to move. The control board 32 drives the control block 33 to move. The control block 33 drives the placement seat 35 to move. The placement seat 35 drives the support plate 31 to move. From the above connection relationship, it can be known that at this time, the horizontal forward and backward movement of the rotating platform 392 can be controlled;
[0056] When the rotating platform 392 is controlled to move to the working area, after the third motor 376 operates, it drives the third gear 377 to rotate. The third gear 377 drives the fourth gear 378 to rotate. The fourth gear 378 drives the connecting rod 391 to rotate. The connecting rod 391 drives the rotating platform 392 to rotate. From the above connection relationship, in this way of controlling the rotation of the rotating platform 392, the drill rod 384 and the door-shaped nail body 397 can be respectively controlled to face the patient in sequence. Moreover, after the drill rod 384 and the door-shaped nail body 397 face the patient, based on this step, small-range angle adjustment can continue to be carried out to adjust the drilling inclination angles of the drill rod 384 and the door-shaped nail body 397 to achieve the purpose of multi-angle drilling. On this basis, when dealing with situations such as when the patient's arm or leg is in a spread state and needs treatment, after the fourth electric push rod 363 operates, it pushes the moving plate 379. The moving plate 379 drives the rack 361 to move. After the rack 361 moves, the fifth gear 362 rotates. The fifth gear 362 drives the first electric push rod 39 to rotate. The first electric push rod 39 drives the U-shaped plate 38 to rotate. From the above operations, it can be known that in this way, the horizontal angles of the drill rod 384 and the door-shaped nail body 397 can be adjusted to meet the operation requirements of the arm or leg placed at different angles;
[0057] After the first electric push rod 39 works, it pushes the U-shaped plate 38 up and down. Accordingly, the overall height of the drill rod 384 and the door-shaped nail body 397 can be adjusted. After the overall height is adjusted, when the second electric push rod 389 works, it can push the long plate 388. The long plate 388 drives the lifting plate 396 to move. At this time, the long plate 388 drives the door-shaped nail body 397 to be pushed along the axis of the lifting plate 396 to achieve the positioning purpose. Similarly, after the third electric push rod 374 works, it pushes the frame plate 381. The frame plate 381 drives the fixed rod 382 to move.
