when the upper pedicle screw is fixed on the lumbar, a screw guide cylinder is firstly installed on an upper fixing cap, the screw guide cylinder realizes the fixation of the screw guide cylinder by matching the internal thread of the installation section screw guide cylinder with the external thread of the upper fixing cap, then the upper pedicle screw is installed on the screw guide cylinder, the external thread of the upper pedicle screw is matched with the internal thread of the positioning section screw guide cylinder, so as to form that the upper pedicle screw moves downwards along the screw guide cylinder, so that the upper pedicle screw cannot deviate when being screwed in and fixed, the accuracy is greatly improved, the error arrangement is avoided, the injury of spinal cord, nerve root and the like is avoided, after the upper pedicle screw is screwed to the bottom, the external thread of the upper pedicle screw is separated from the internal thread of the positioning section screw guide cylinder and matched with the internal thread of the upper fixing cap, the pedicle screw is fixedly installed on a triangular fixing frame, and finally the, in the same way, the lower pedicle screw and the lateral articular process screw are fixed in the same way, so that deviation is avoided when screwing in and fixing is realized, the accuracy is greatly improved, misplacement is avoided, the arrangement of the upper pedicle screw countersunk head inner hexagonal hole, the lower pedicle screw countersunk head inner hexagonal hole and the lateral articular process screw countersunk head inner hexagonal hole is more convenient to install, the arrangement of the left side clamp, the right side clamp and the lower side clamp ensures that multiple connection is realized among the upper guide plate, the left lower guide plate and the right lower guide plate, the whole guide plate is more stable, the left side clamp, the right side clamp and the lower side clamp are convenient to disassemble, and only sliding disassembly is needed,
after the upper pedicle screw, the lower pedicle screw and the lateral zygopophysis screw are all arranged on the triangular fixing frame, the guide plate is detached, the left clamp, the right clamp and the lower clamp are detached to release the locking when the guide plate is detached, then inserting a fine needle from the first upper guide plate detaching hole to jack the first left lower guide plate hook, releasing the locking between the first left lower guide plate hook and the first upper guide plate clamping hole, inserting a fine needle from the second upper guide plate detaching hole to jack the right lower guide plate hook, so that the right lower guide plate hook and the second upper guide plate clamping hole are unlocked, a fine needle is inserted from the right lower guide plate dismounting hole to jack the second left lower guide plate hook, so that the second left lower guide plate hook and the right lower guide plate clamping hole are unlocked, thereby dividing the guide plate into an upper guide plate, a left lower guide plate and a right lower guide plate for disassembly, thus realizing positioning and avoiding the influence on body health caused by the guide plate remaining in the body of a patient,
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.
