In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

The utility model provides a nail taking device for orthopedic surgery as shown in figures 1-6, which comprises a bracket 1, wherein the top of the bracket 1 is fixedly provided with a first motor 2, the output end of the first motor 2 is connected with a screw rod 3 in a transmission way, the outside of the screw rod 3 is sleeved with a sliding plate 4, the top of the sliding plate 4 is fixedly provided with a second motor 5, the output end of the second motor 5 is connected with a nail taking device 6 in a transmission way, the bottom of the bracket 1 is welded with a bearing plate 7, a clamping plate 8 is fixedly arranged above the bearing plate 7, one side of the outside of the clamping plate 8 is provided with a knob 9, the output end of the knob 9 is connected with a first rotating shaft 10 in a transmission way, the outside of the first rotating shaft 10 is sleeved with an upper clamping ring 11, the outside of the first rotating shaft 10 is connected with a belt 12, the other end of the belt 12 is connected with a connecting shaft 13, and one end of the connecting shaft 13 is connected with a second rotating shaft 14 in a thread way, a lower clamping ring 16 is sleeved outside the second rotating shaft 14, and an adjusting button 17 is installed on one side of the outside of the supporting plate 7.

Further, in the above technical solution, the upper clamping ring 11 and the lower clamping ring 16 are arranged in a "C" shape, and the size of the upper clamping ring 11 is equal to that of the lower clamping ring 16, the upper clamping ring 11 and the lower clamping ring 16 arranged in a "C" shape are beneficial to conform to the radian of the arm and the leg to make the arm and the leg more fit, and the clamping effect is conveniently performed by using the upper clamping ring 11 and the lower clamping ring 16.

Further, in above-mentioned technical scheme, the surface two-thirds department of connecting axle 13 is provided with the external screw thread, the inside of second pivot 14 is provided with the internal thread, internal thread and external screw thread phase-match, and the rotation direction of the external screw thread setting to and connecting axle 13 is opposite direction, and the external screw thread through reverse setting can be favorable to being opposite direction with the rotation direction of second pivot 14 and the rotation direction of first pivot 10 to be convenient for synchronous with last clamp ring 11 and the change of clamp ring 16 down adjusting and angle.

Further, in the above technical scheme, the fixed bracing piece 15 that is provided with in outside of second pivot 14, the quantity of bracing piece 15 sets up to two, two bracing piece 15 is about second pivot 14 symmetric distribution, is favorable to second pivot 14 through two bracing pieces 15 in the pivoted in-process through the effect that can be fine play a support to prevent that second pivot 14 can take place the phenomenon of removal when connecting axle 13 rotates.

Further, in above-mentioned technical scheme, grip block 8, last clamp ring 11 and lower clamp ring 16 constitute the centre gripping subassembly jointly, the quantity of centre gripping subassembly sets up to two sets of, two sets of centre gripping subassembly is favorable to adjusting according to patient's girth through setting up of two sets of centre gripping subassemblies about bearing board 7 symmetric distribution, makes it to be suitable for not unidimensional centre gripping, and through the use of centre gripping subassembly, makes things convenient for the centre gripping patient to get the position of nail, has prevented to take place the phenomenon of displacement at the in-process of getting the nail to improve and get nail work efficiency.

Further, in the above technical scheme, the output end of adjusting knob 17 is connected with screw rod 18 in a transmission manner, opposite threads are arranged on the outside of screw rod 18, sleeve plates 19 are connected to both ends of the outside of screw rod 18 in a threaded manner, and opposite threads arranged on the surface of screw rod 18 are beneficial to moving two groups of clamping assemblies relatively or oppositely, so that the effect of adjusting the position distance is well achieved.

This practical theory of operation:

referring to the attached drawings 2-4 of the specification, when a patient needs to be nailed, the arm or the leg of the patient needs to be fixedly clamped so as to generate displacement, the girth of the arm or the leg of the patient is observed at first, then the size of the clamping component is adjusted according to the girth, the first rotating shaft 10 is driven to rotate by rotating the knob 9, the first rotating shaft 10 directly drives the upper clamping ring 11 to rotate by rotating, then the first rotating shaft 10 drives the connecting shaft 13 to rotate by the belt 12 through the connection of the belt 12, because the external thread is arranged on one part of the surface of the connecting shaft 13 and the internal thread matched with the external thread is arranged in the second rotating shaft 14, the second rotating shaft 14 connected by the thread is driven to rotate when the connecting shaft 13 rotates, and the second rotating shaft 14 can well play a supporting role through the supporting rod 15 in the rotating process, therefore, the phenomenon that the second rotating shaft 14 moves when the connecting shaft 13 rotates is prevented, and the additional threads arranged on the connecting shaft 13 are opposite to the rotating direction, so that the rotating direction of the second rotating shaft 14 is opposite to the rotating direction of the first rotating shaft 10 when the connecting shaft 13 rotates, the rotation of the upper clamping ring 11 and the rotation of the lower clamping ring 16 are opposite, the angle between the upper clamping ring 11 and the lower clamping ring 16 can be adjusted, the upper clamping ring 11 and the lower clamping ring 16 can be adjusted with the girth of a patient conveniently, the sizes of the two clamping components are adjusted, the legs and the arms of the patient can be clamped and fixed better, and the nail taking work is facilitated;

referring to the attached drawing 1 and fig. 5-6 of the specification, when the size is adjusted according to the circumference of a patient, the adjusting button 17 is rotated to drive the screw rod 18 to rotate, the screw rod 18 rotates to drive the two sleeve plates 19 to move, due to the fact that the screw rod 18 is provided with opposite threads, the sleeve plates 19 can move oppositely or reversely until the two groups of clamping components move to the outer portion of the clamping position of the patient to be clamped, then the first motor 2 is started to drive the screw rod 3 to rotate, the screw rod 3 rotates to drive the sliding plate 4 to move up and down, the lifting sliding plate 4 drives the nail extractor 6 until the nail extractor 6 moves to the optimal height for taking nails, and then the second motor 5 is continuously started to drive the nail extractor 6 to rotate to pull out the bone nails on the bone of the patient.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
