Then position of the locking pin 92 of connection mechanism 9 in the adjustment hole 71 of the first tranverse connecting rod 7 is locked with locking cap 93 again.
Embodiment 2 is identical with the other structures of embodiment 1.
Tranverse connecting rod of the invention has universal adjustment and fixes two kinds of structure types, can be according to need in specific surgical procedure
Select suitable structure type.
If selecting fixed structure form, i.e. the first tranverse connecting rod 7 and arc connection sheet 91 and the second tranverse connecting rod 8 are integral type
Structure, use process are:
A, after being previously implanted two pedicle nail nail seats in the course of surgery, then first by pitman radially across corresponding nail seat
It is interior, then again by 12 assembly connection of the first engaging lug of the plug-in opening 71 of the first tranverse connecting rod 7 and the first nail seat 1, the second tranverse connecting rod 8
Plug-in opening 81 and the second nail seat 2 22 assembly connection of the second engaging lug, since horizontal continuous cropping is firmly directly used in nail by the present invention
On seat, nail seat opening expansion is prevented, this kind of structure can play a protective role to nail seat；
B, after being packed into tranverse connecting rod, then it is respectively charged into corresponding locking plug into each nail seat, locking plug is made to pass through corresponding horizontal company
Bar applies active force, while locking tranverse connecting rod and pitman, prevents from moving axially, completes the horizontal company of two pedicle nail nail seats.
If selecting universal adjustment structure type, use process is:
A, after in the course of surgery, being previously implanted the second nail seat 2, according to operation it needs to be determined that the first nail seat 1 implantation position, so
Afterwards by pitman radially across corresponding nail seat, then again by one end of the first tranverse connecting rod 7 and 1 assembly connection of the first nail seat,
One end of two tranverse connecting rods 8 and 2 assembly connection of the second nail seat,
B, class rotates tranverse connecting rod as needed after being packed into tranverse connecting rod, then corresponding locking plug is respectively charged into each nail seat, makes
Locking plug applies active force by corresponding tranverse connecting rod, while locking tranverse connecting rod and pitman, prevents from moving axially,
C, according to operation needs, locking pin 92 is determined in the position of the adjustment hole 71 of the first tranverse connecting rod 7, then by the locking pin 92
Be interior across the elongated adjustment hole 71 of the first tranverse connecting rod 7 and the round connecting hole 81 of the second tranverse connecting rod 8, then with locking cap 93 by its
It is fixed, complete the horizontal company of two pedicle nail nail seats.
Tranverse connecting rod of the present invention is directly assembled with nail seat, prevents tranverse connecting rod from rotating around nail seat, has rotation preventing function, connection
There is universal joint at place, and locking device has the function of universal adjustment, is connect by tranverse connecting rod with pedicle of vertebral arch screw nail seat, then pass through cross
Connecting rod universal structure, last locking device lock to form stable fixed structure, instead of the both ends point of connecting bar horizontal in prior art
Do not existed using lock screw with horizontal the advantages of even detaining the technical solution being fixedly connected, designing in this way on pitman or locking cap
In: first, not only reducing the quantity of surgery implant, reduce operation incisura, and reduces operation cost；Second, will
Horizontal continuous cropping is firmly directly used in nail seat, and deform, be broken etc. during effectively preventing tranverse connecting rod and horizontal even padlock tightly mistake
The risk of effect, increases the stability of structure, and improves safety in utilization；Third, since horizontal continuous cropping firmly directly being used
In in nail seat, it is ensured that the problem of nail seat opening expansion will not occur during being screwed into nail seat for locking cap, play protection to nail seat
Effect, so that integrally fixation will not fail pedicle nail, and is ensured.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
