The beneficial effect of the treatment fixator of protrusion of lumber intervertebral disc provided by the utility model is：Guide plate is placed on during use With patient, the compactness of guide plate is higher, and positioning is more accurate, and triangle fixed mount is arranged on guide plate, triangle fixed mount On upper locking cap flange collar insertion guide plate in the recessed circle of through hole, lead under the lower locking cap flange collar insertion guide plate on triangle fixed mount In the recessed circle in hole, realize that the positioning of triangle fixed mount will not be subjected to displacement,

When upper pedicle screw is fixed on lumbar vertebrae, first screw guide cylinder is arranged on upper locking cap, screw guide cylinder It is to coordinate to realize that screw guide cylinder is fixed with upper locking cap external screw thread by construction section screw guide cylinder internal thread, then by upper vertebra Pedicle screw on screw guide cylinder, fix external screw thread and match with positioning section screw guide cylinder internal thread by upper pedicle screw Close, pedicle screw moves down along screw guide cylinder in formation, pedicle screw is not wandered off when screwing in fixed, accurate True rate greatly improves, and will not by mistake put, avoid spinal cord, nerve root equivalent damage, after upper pedicle screw is screwed into bottom soon, upper pedicle of vertebral arch screw The fixed external screw thread of nail depart from positioning section screw guide cylinder internal thread and with upper locking cap screw-internal thread fit, realize that pedicle screw is consolidated Finally screw guide cylinder is pulled down from upper locking cap, similarly descends pedicle screw and side on triangle fixed mount in Dingan County Interarticular screw also in this way, will not be wandered off when realizing and screwing in fixed when fixed, accuracy rate greatly improves, and will not be missed Put, pedicle screw countersunk head inner hexagonal hole, lower pedicle screw countersunk head inner hexagonal hole and lateral joint are dashed forward in screw countersunk head in setting Hexagon ring is easier for installation, sets left side clip, right side clip and downside clip so that upper guide plate, lower-left guide plate and the right side There are more reconnections, the entirety of guide plate is more firm, and left side clip, right side clip and the dismounting of downside clip between bottom guide It is convenient, dismounting only need to be slided,

After upper pedicle screw, lower pedicle screw and lateral joint dash forward screw all on triangle fixed mount, Guide plate is pulled down, and left side clip, right side clip and downside clip first are pulled down into releasing locking during dismounting, then torn open from the first upper guide plate Unload hole insertion fine needle to open the first lower-left guide plate grab top so that the first lower-left guide plate grab and the first upper guide plate hole clipping are released and locked Only, bottom right guide plate grab top is opened from the second upper guide plate removal hole insertion fine needle so that bottom right guide plate grab and the second upper guide plate Hole clipping releases locking, opens the second lower-left guide plate grab top from bottom right guide plate removal hole insertion fine needle so that the second lower-left guide plate Grab releases locking with bottom right guide plate hole clipping, is dismantled so as to which guide plate is divided into upper guide plate, lower-left guide plate and bottom right guide plate, so i.e. It can position, and can, which avoids guide plate from staying in, influences health in patient body,

It should also be noted that, the side muscle of human body need to only be peeled off, you can realize fixed and lateral solid up and down It is fixed, realized by upper pedicle screw and lower pedicle screw and fixed up and down, entering the prominent screw of lateral joint by a side realizes side To fixation, the prominent screw of upper pedicle screw, lower pedicle screw and lateral joint is connected by triangle fixed mount, forms three The stable fixed relationship in angle, reaches the purpose of fixation, realizes Minimally Invasive Surgery, substantially reduce the pain that patient bears, perform the operation Efficiency greatly improves.

Further include it is upper reinforcing nut, it is lower reinforcing nut and side reinforce nut, it is described it is upper reinforcing nut with, it is described on Reinforce nut, lower reinforcing nut and side to reinforce on nut and be equipped with countersunk head inner hexagonal hole, the upper reinforcing nut and upper locking cap It 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, makes Obtain to install respectively on upper locking cap, the oblique locking cap of lower locking cap and left side and reinforce nut, lower reinforcing nut and side reinforcing Intensity is higher after nut.

Further the guide plate turns up paster provided with upper arc and arc lower turns up paster so that guide plate compactness is more Height, locating effect are more preferable.

Further the upper lateral connection post includes square upper lateral connection post and semicircle upper lateral connection post, described With being fixedly connected at the top of square upper lateral connection post, the lower vertical connecting pole includes for the bottom of lateral connection post in semicircle Square lower vertical connecting pole and it is semicircle under vertical connecting pole, it is described it is semicircle under vertical connecting pole bottom with it is square lower vertical It is fixedly connected at the top of connecting pole, the oblique connecting pole in left side includes vertically connecting under the oblique connecting pole in square left side and semicircle Connect post, the semi-circular left skew back to the bottom of connecting pole with being fixedly connected at the top of the oblique connecting pole in square left side, this knot Structure make it that the bulk strength of triangle fixed mount is higher.

The utility model will be further described with reference to the accompanying drawings and detailed description.
