Abstract
The utility model discloses a marrow inner nail with lock which can replace five kinds of compound bags that are applied in different fracture part of the thigh bone. Three proximal end lock pin hole devices are provided so that the lock pin can be crossed vertically or obliquely upper left or right with the degree of 45 degrees or the lower left or right with the same degrees. The utility model has the similar functions of common marrow inner nail with lock, G-K nail and rebuild nail. The remote end device can be freely installed with two lock pins to be applied as common remote end lock or the remote end device can be provided with three lock pins to be applied as thigh bone condyles nail.
Description
Affiliated technical field
This utility model relates to a kind of orthopaedics inner fixing device of medical domain, especially can make five kinds of single femur intramedullary nail with lock be simplified to a kind of femur composite band lock intramedullary nail.
Background technology
At present, known femur intramedullary nail with lock divides five kinds because of it is suitable for different fracture sites: follow closely on plain edition intramedullary nail with lock, G-K nail, coffee nail, reconstruction nail, the condyle of femur.The basic structure of all nails is that a main nail and two ends are made up of the intersection pinning respectively, and the difference in them is far away, near pinning mode difference.And each nail all is furnished with one and overlaps complicated accordingly guider, makes troubles for producing and selling increase cost and use.
Summary of the invention
The technical problem that solves is: in order to overcome the deficiency that waits of a great variety of existing femur intramedullary nail with lock, this utility model provides a kind of femur composite band lock intramedullary nail, this nail not only can replace five kinds of femur intramedullary nail with lock that are applicable to femur different parts fracture, and can reduce cost to producing and selling, increase easy to use.
The technical scheme that its technical problem that solves this utility model adopts is: on a femoral interlocking nail, near, far-end has compound pinning aperture apparatus.Near-end device: three holes are arranged in the near-end 80mm, and three hole appearance are respectively water droplet shape, ellipse, turn one's coat and drip a shape from top to bottom, and pinning promptly can be crossed to the left and right, also can to upper left or following, upper right or following 45 ° tiltedly wear.Far end device: two cross-drilled holes are arranged in the far-end 80mm, and the edge of distal aperture is apart from main nail far-end 5mm, and there is same diameter groove in the place ahead middle in two holes, main nail, this groove promptly is used as the locating slot of locating rod, also can lay one piece of pinning, make it have the effect of following closely on the condyle of femur, promptly " follow closely on the condyle in the marrow ".
The beneficial effects of the utility model are: a kind ofly replace five kinds of numerous and diverse femur intramedullary nail with lock, reduce cost to producing and selling, provide easy to use, reduce the complication of operation.

The specific embodiment
In Fig. 1, be the compound locking nail hole of femur composite band lock intramedullary nail far-end (1) (2) (A), lay pinning groove (3), two pieces of pinnings can be installed arbitrarily do general distal locking nail use, three pieces of pinnings also can be installed make nail usefulness on the condyle of femur.(B) be femur composite band lock intramedullary nail, the compound locking nail hole of near-end (6) promptly can cross pinning to the left and right, also can to upper left or following, upper right or following 45 ° tiltedly wear.
In Fig. 2, a pinning (a 7) upwards left side or right 45 ° tiltedly is through at when locking nail hole (6) is locked in the neck of femur head and can replaces coffee nail (A) treatment intertrochanteric fracture; Cross two pinnings (7) and replace normal tape lock intramedullary nail (B) when locking nail hole (6), be used for the treatment of fracture of shaft of femur; A pinning (7) can replace G-K nail (C) to bottom left or right 45 ° when tiltedly being through at locking nail hole (6), is used for the treatment of the following fracture of femoral bone tuberosity; Two pinnings (a 7) upwards left side or right 45 ° tiltedly are through at and can replace rebuilding nail (D) when locking nail hole (6) is locked in the neck of femur head, treatment intertrochanteric fracture or complicated serious tuberosity and bottom fracture thereof.
In Fig. 3, pinning (4) can replace intramedullary nail treatment supracondylar fracture of the femur on the condyle of femur during cross locking continuously at two distal locking nail holes (1) (2), a prelocalization groove (3).Also available two pinnings (4) are installed arbitrarily in distal locking nail hole (1) (2) (3), as the far-end lock of various forms femur intramedullary nail with lock.
Claims (3)
1, a kind of femur composite band lock intramedullary nail also is in femoral bone cavitas medullaris, and multi-form pinning is laid by needed function in the two ends of main nail, reaches the purpose of treatment fracture.It is characterized in that: on a femoral interlocking nail, near, far-end has compound pinning aperture apparatus.Near-end device: three holes are arranged in the near-end 80mm, and three hole appearance are respectively water droplet shape, ellipse, turn one's coat and drip a shape from top to bottom, and pinning promptly can be crossed to the left and right, also can to upper left or following, upper right or following 45 ° tiltedly wear.Far end device: two cross-drilled holes are arranged in the far-end 80mm, and there is the groove of same diameter in the place ahead middle in two holes, main nail, and two or three pieces of pinnings can laterally be installed arbitrarily.
