Description
Technical field
The present invention relates to a kind of spinal orthopedic bar apparatus for placing, for Via Posterior Spinal Approach Minimally Invasive Surgery.
Background technology
In Via Posterior Spinal Approach Minimally Invasive Surgery, restoring backbone is made by the mating reaction of pedicle screw and Orthopedic rod, pedicle screw is arranged on spinal column relevant position by usual employing pedicle screw clamping device, again Orthopedic rod is inserted in the U-lag of pedicle screw, by interior pinning, Orthopedic rod is fixed in the U-lag of pedicle screw, because the U-lag size of pedicle screw is limited, in Minimally Invasive Surgery, require that Orthopedic rod can directly be inserted in the U-lag of pedicle screw by doctor exactly, very high to the requirement of doctor, and operating difficulties.
In order to address this problem, partial monopoly discloses on pedicle screw clamping device, to offer an opening solve this technical problem, such as US Patent No. 2011/0040328A1 just discloses a kind of spinal orthopedic bar apparatus for placing, accompanying drawing 17 is the spinal orthopedic bar apparatus for placing schematic diagram of US Patent No. 2011/0040328A1, the clamping part of pedicle screw clamping device 1 is provided with female thread 17, female thread 17 matches with the external screw thread of interior pinning 16, pressing device 8 is relied on to rotate interior pinning 16 under the female thread 17 of pedicle screw clamping device 1 guides, Orthopedic rod 11 is placed in pedicle screw 19.Pedicle screw 19 top has U-lag 20, and this U-lag 20 matches with the U-shaped opening of pedicle screw clamping device 1.Wherein, after pedicle screw clamping device 1 clamps pedicle screw 19, the female thread 17 of pedicle screw clamping device 1 forms a continuous print screw thread collection, so that Orthopedic rod 11 is pressed in the U-lag 20 of pedicle screw 19 by interior pinning 16 smoothly with the female thread 18 of pedicle screw 19.The major defect of this technology is that the pushing of Orthopedic rod 11 relies on the interior external screw thread of pinning 16 and the female thread 17 of pedicle screw clamping device 1 to guide to push, therefore this technology necessarily requires the female thread 17 of pedicle screw clamping device 1 to be positioned at the clamping part of pedicle screw clamping device 1, the female thread 17 of pedicle screw clamping device 1 forms a continuous print screw thread collection with the female thread 18 of pedicle screw 19, a kind of pedicle screw must coordinate a kind of pedicle screw clamping device to use, make poor universality, and if the female thread 17 of pedicle screw clamping device 1 is oversize, Orthopedic rod 11 is then installed need to spend the more time, if female thread 17 is too short, that then leaves that Orthopedic rod 11 penetrates the U-shaped opening of pedicle screw clamping device 1 for can will become too little by operative space.
Based on above-mentioned objective fact, a kind of in operation versatility spinal orthopedic bar apparatus for placing that is good, convenient operation become this area problem demanding prompt solution.
