Put, in setting, 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
Hexagon ring is easier for installation,
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 inserts fine needle from the first upper guide plate removal hole and back down the first lower-left guide plate grab so that the first lower-left during dismounting
Guide plate grab and the first upper guide plate hole clipping release locking, insert fine needle by bottom right guide plate grab top from the second upper guide plate removal hole
Open so that bottom right guide plate grab and the second upper guide plate hole clipping release locking, left by second from bottom right guide plate removal hole insertion fine needle
Bottom guide grab backs down so that the second lower-left guide plate grab releases locking with bottom right guide plate hole clipping, thus guide plate is divided into leading
Plate, lower-left guide plate and the dismounting of bottom right guide plate, so can position, and be avoided that guide plate is stayed impact body in patient body and is good for again
Health,
Also, it should be noted only the side muscle of human body need to be peeled off, you can realize fixing up and down and laterally solid
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 side
To fixation, the prominent screw of upper pedicle screw, lower pedicle screw and lateral joint is connected by triangle fixed mount, forms three
Fixed relationship is stablized at angle, reaches the purpose of fixation, realizes Minimally Invasive Surgery, so that the misery that patient bears is substantially reduced, operation
Efficiency greatly improves.
