It is provided by the present invention for the beneficial effect of the holder of lumbar spinal fusion:Guide plate is placed on patient's body when usingOn, the laminating degree of guide plate is higher, and more accurately, triangle fixed mount is arranged on guide plate positioning, upper on triangle fixed mountThe recessed circle of lower locking cap flange collar insertion guide plate lower through-hole on locking cap flange collar insertion guide plate in the recessed circle of through hole, on triangle fixed mountIt is interior, realize that triangle fixed mount positioning will not be subjected to displacement,
When upper pedicle screw is fixed on lumbar vertebra, first screw guide cylinder is arranged on upper locking cap, screw guide cylinderIt is to coordinate to realize that screw guide cylinder is fixed with upper locking cap external screw thread by construction section screw guide cylinder female thread, then by upper vertebraPedicle screw is mounted on screw guide cylinder, and upper pedicle screw is fixed external screw thread and matched with positioning section screw guide cylinder female threadClose, pedicle screw is moved down along screw guide cylinder in formation, make pedicle screw not wander off when screwing in fixed, it is accurateReally rate is greatly improved, and will not be put by mistake, it is to avoid spinal cord, nerve root equivalent damage, upper pedicle screw is screwed into soon behind bottom, upper pedicle of vertebral arch screwThe fixed external screw thread of nail depart from positioning section screw guide cylinder female thread and with upper locking cap screw-internal thread fit, realize that pedicle screw is consolidatedDingan County is mounted on triangle fixed mount, finally pulls down screw guide cylinder from upper locking cap, and pedicle screw and side are descended in the same mannerInterarticular screw is also adopted by this mode when fixed, realizes that screw-in will not wander off when fixed, accuracy rate is greatly improved, will not be by mistakePut, in setting in the prominent screw countersunk head of pedicle screw countersunk head inner hexagonal hole, lower pedicle screw countersunk head inner hexagonal hole and lateral jointHexagon ring is easier for installation, and spring is connected and downside is connected bullet by arranging be connected spring, right side of left sideSpring so that have between upper guide plate, lower-left guide plate and bottom right guide plate and reconnect more, the entirety of guide plate is more consolidated, and it is leftBe connected spring, right side of side is connected spring and the downside spring dismounting that is connected is very convenient, wherein left side connection is solidDetermine spring in the left groove so that the left side spring that is connected is installed and more consolidated, and will not be subjected to displacement, right side connectionFixed spring is arranged in right groove so that the right side spring that is connected is installed and more consolidated, and will not be subjected to displacement, and downside connectsFixed spring is connect on the groove of downside so that the downside spring that is connected is installed and more consolidated, and will not be subjected to displacement,
After the prominent screw of upper pedicle screw, lower pedicle screw and lateral joint is all arranged on triangle fixed mount,Guide plate is pulled down, and be first connected spring, right side of left side is connected into spring and the downside spring that is connected is pulled down during dismounting, soAfterwards the first lower-left guide plate grab is backed down from the first upper guide plate removal hole insertion fine needle so that the first lower-left guide plate grab and firstUpper guide plate hole clipping releases locking, backs down bottom right guide plate grab from the second upper guide plate removal hole insertion fine needle so that bottom right guide plateGrab and the second upper guide plate hole clipping release locking, and from bottom right, guide plate removal hole insertion fine needle backs down the second lower-left guide plate grab,So that the second lower-left guide plate grab releases locking with bottom right guide plate hole clipping, so as to guide plate is divided into into upper guide plate, lower-left guide plate and the right sideBottom guide is dismantled, and so can be positioned, and being avoided that guide plate is stayed in patient body again affects healthy,
Also, it should be noted that only need to peel off to the side muscle of human body, you can realize fixed and lateral solid up and downIt is fixed, realize fixing up and down by upper pedicle screw and lower pedicle screw, the prominent screw of lateral joint is entered by a side and realizes sideTo fixation, the prominent screw of upper pedicle screw, lower pedicle screw and lateral joint is connected by triangle fixed mount, forms threeThe stable fixed relationship in angle, reaches the purpose of fixation, realizes Minimally Invasive Surgery, substantially reduces the pain that patient bears, and performs the operationEfficiency is greatly improved.
Further include that upper reinforcing nut, lower reinforcing nut and side reinforce nut, the upper reinforcing nut with, it is described onReinforce on nut, lower reinforcing nut and side reinforcing nut and be equipped with countersunk head inner hexagonal hole, the upper reinforcing nut and upper locking capIt is engaged, the lower reinforcing nut is engaged with lower locking cap, and the side reinforces nut and is engaged with the oblique locking cap in left side, makesObtain and reinforcing nut, lower reinforcing nut and side reinforcing are respectively mounted on upper locking cap, the oblique locking cap of lower locking cap and left sideIntensity is higher after nut.
Further the guide plate is provided with that arc turns up paster and arc lower turns up paster so that guide plate laminating degree is moreHeight, locating effect is more preferable.
Further the upper lateral connection post includes square upper lateral connection post and semicircle upper lateral connection post, describedThe bottom of lateral connection post is fixedly connected with the top of square upper lateral connection post in semicircle, and the lower vertical connecting pole includesVertical connecting pole under square lower vertical connecting pole and semicircle, the bottom of vertical connecting pole is lower vertical with square under the semicircleIt is fixedly connected at the top of connecting pole, the oblique connecting pole in the left side includes vertically connecting under the oblique connecting pole in square left side and semicirclePost is connect, the semi-circular left skew back to the bottom of connecting pole is fixedly connected with the top of the oblique connecting pole in square left side, this knotStructure causes the bulk strength of triangle fixed mount higher.
With reference to the accompanying drawings and detailed description the invention will be further described.
