when the upper pedicle screw, the lower pedicle screw and the lateral articular process screw are all arranged on the triangular fixing frame, the guide plate is detached, the left side locking plate, the right side locking plate and the lower side locking plate are detached to release the locking when the upper pedicle screw, the lower pedicle screw and the lateral articular process screw are detached, then the thin needle is inserted from the detaching hole of the first upper guide plate to jack the first lower guide plate hook open, so that the first lower guide plate hook and the first upper guide plate clamping hole are released from the locking, the thin needle is inserted from the detaching hole of the second upper guide plate to jack the right lower guide plate hook open, so that the right lower guide plate hook and the second upper guide plate clamping hole are released from the locking, the guide plate is divided into the upper guide plate, the left lower guide plate and the right lower guide plate to be detached, the positioning can be realized, the influence on the health of a patient caused by the guide plate remaining in the body can be avoided,
it should also be noted that the upper and lower fixation and the lateral fixation can be realized only by peeling one side muscle of the human body, the upper and lower fixation can be realized by the upper pedicle screw and the lower pedicle screw, the lateral fixation can be realized by one lateral side-entering articular process screw, and the upper pedicle screw, the lower pedicle screw and the lateral articular process screw are connected and fixed by the triangular fixing frame to form a triangular stable fixation relation, so that the purpose of firm fixation is achieved, the minimally invasive surgery is realized, the pain born by the patient is greatly reduced, and the surgery efficiency is greatly improved.
Further including last reinforcement nut, consolidate nut and side reinforcement nut down, go up reinforcement nut with, go up reinforcement nut, all be equipped with the hexagon socket in the countersunk head on reinforcement nut and the side reinforcement nut down, it cooperatees with last locking nut to go up reinforcement nut, it cooperatees with lower locking nut to consolidate the nut down, the side is consolidated the nut and is cooperateed with left side slant locking nut for install respectively on last locking nut, locking nut and left side slant locking nut down and consolidate the nut back strength higher with the side.
Furthermore, the upper arc-shaped folded patch and the lower arc-shaped folded patch are arranged on the guide plate, so that the fitting degree of the guide plate is higher, and the positioning effect is better.
Further go up horizontal spliced pole including square horizontal spliced pole and the horizontal spliced pole on the semicircle, the top fixed connection of the bottom of the horizontal spliced pole on the semicircle and square horizontal spliced pole on, vertical spliced pole includes vertical spliced pole under square vertical spliced pole and the semicircle, the bottom of vertical spliced pole and the top fixed connection of the vertical spliced pole under the semicircle, the slant spliced pole in left side includes square left side slant spliced pole and the vertical spliced pole under the semicircle, the bottom of the slant spliced pole in semicircle left side and the top fixed connection of square left side slant spliced pole, this kind of structure makes the bulk strength of triangle-shaped mount higher.
The invention is further described with reference to the following figures and detailed description.
