DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-4 The utility model discloses a limb placement structure for nail removal, comprising a placement device 1, a positioning device 2 is arranged on the top of the placement device 1, the number of the positioning devices 2 is two, and the two positioning devices 2 are located at the front and rear ends of the placement device 1; the placement device 1 comprises a placement table 3, a placement groove 4 is provided on the top of the placement table 3, and a positioning groove 5 is provided on the top of the placement groove 4; the positioning device 2 comprises a positioning arc plate 7, a slide rail 15 and a hinged tooth pin 12, the bottom ends of the positioning arc plate 7 are respectively fixedly connected with a rack 8 and a vertical rod 9, the slide rail 15 is fixedly connected to the inner wall of the left positioning groove 5, the hinged tooth pin 12 is hinged to the inner wall of the left positioning groove 5, the rack 8 The vertical rod 9 is respectively located inside the positioning groove 5, and the inner wall of the slide rail 15 is slidably connected with a gear 17 through a moving rod 16, and the gear 17 and the hinged tooth pin 12 are both meshed with the rack 8; by setting the positioning device 2, the rack 8 can be lifted and lowered along the direction of the slide rod 11 through the rotation of the gear 17, so that the rack 8 can drive the protective arc plate to move toward the patient's limb inside the placement groove 4, so that the protective arc plate and the placement groove 4 can clamp the patient's limb therein, thereby achieving the purpose of taking effective positioning measures for the patient's limb with bone nails, avoiding the patient's limb involuntary movement due to pain during the nail removal process, and ensuring the normal progress of the nail removal work.
[0022] Specifically, the interior of the placement groove 4 is provided with anti-skid protrusions 6, and the anti-skid protrusions 6 are soft silicone grease dots.
[0023] In this embodiment, the anti-slip protrusions 6 can be used to lift the patient's limbs located inside the placement groove 4, thereby increasing the placement friction between the patient's limbs and the placement groove 4, thereby improving the patient's stability when removing the nails.
[0024] Specifically, the opposite sides of the rack 8 and the vertical rod 9 are both provided with a follower block 10 , the inner wall of the positioning groove 5 is fixedly mounted with a slide bar 11 , and the follower block 10 is slidably connected to the surface of the slide bar 11 .
[0025] In this embodiment, the follower block 10 can follow the rack 8 and the vertical rod 9 to slide along the surface of the slide rod 11, so that the movement of the rack 8 and the vertical rod 9 is more stable.
[0026] Specifically, a damping spring rod 13 is provided on the outer side of the hinge pin 12, and the other end of the damping spring rod 13 is connected to the inner wall of the vertical groove. A rotating rod 14 is fixedly installed on the front end of the hinge pin 12, and the rotating rod 14 extends to the front side of the placement table 3.
[0027] In this embodiment, the automatic rebound resilience of the damping spring rod 13 can drive the hinged tooth pin 12 to automatically contact the rack 8, and then produce the meshing positioning process, thereby avoiding the situation where the rack 8 automatically slides down due to the gravity factor of the positioning arc plate 7, and ensuring the positioning effect of the positioning arc plate 7.
[0028] Specifically, the moving rod 16 is located inside the slide rail 15 and is slidably connected to the inner wall of the slide rail 15. The front end of the moving rod 16 is rotatably connected to the back side of the gear 17. The front end of the gear 17 is fixedly equipped with a turning handle 18, which extends to the front side of the placement table 3.
[0029] In this embodiment, when the positioning arc plate 7 does not need to be rotated, the turning handle 18 is pulled, so that the turning handle 18 drives the gear 17 to slide inside the slide rail 15 through the moving rod 16, causing the gear 17 to gradually move away from the rack 8, so that the meshing transmission between the gear 17 and the rack 8 is released, so that the rack 8 will neither drop nor rise.
[0030] When in use, the patient's limb with bone screws is first placed in the placement groove 4, and then the rotating rod 14 is rotated so that the rotating rod 14 can drive the hinge pin 12 to rotate, so that the hinge pin 12 can rotate with the rotating rod 14 as the center of the circle, so that the hinge pin 12 is separated from the rack 8, and then the gear 17 is driven to rotate by the turning handle 18, so that the rotation of the gear 17 can drive the rack 8 to move, so that the movement of the rack 8 drives the placement arc plate to move toward the patient's limb inside the placement groove 4, so that the inner side of the placement arc plate gradually contacts the patient's limb, so that the protective arc plate and the placement groove 4 can clamp the patient's limb therein;
[0031] Then, the rotating rod 14 is loosened, so that the automatic rebound elasticity of the damping spring rod 13 can drive the articulated tooth pin 12 to rebound to the initial position, so that the articulated tooth pin 12 is meshed with the rack 8 again, so that the articulated tooth pin 12 limits the height point of the rack 8, and then the turning handle 18 is pulled, so that the turning handle 18 drives the gear 17 to slide inside the slide rail 15 through the moving rod 16, causing the gear 17 to gradually move away from the rack 8, so that the meshing transmission between the gear 17 and the rack 8 is released at this time, so that the rack 8 is limited under the positioning of the articulated tooth pin 12.
[0032] To sum up, the limb placement structure for nail removal, by setting a positioning device 2, utilizes the rack 8 to be able to move up and down along the direction of the slide rod 11 through the rotation of the gear 17, so that the rack 8 can drive the protective arc plate to move toward the patient's limb inside the placement groove 4, so that the protective arc plate and the placement groove 4 can clamp the patient's limb therein, thereby achieving the purpose of taking effective positioning measures for the patient's limb with bone nails, avoiding the patient's limb involuntary movement due to pain during the nail removal process, and ensuring the normal progress of the nail removal work.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
