By using the steel plate fixer, temporary fracture fixation after long bone fracture reduction can be performed, pressing of the fracture end and temporary fixation through the steel plate can be realized, the operation can be convenient, and the operation time can be saved, therefore the steel plate fixer is favorable for fracture union.
Description
Technical field
This utility model relates to a kind of orthopaedics reduction of the fracture steel plate holder, the interim fracture fixation behind the especially suitable long bone fracture operative reduction, fracture end pressurization and the temporary fixed operating theater instruments of steel plate.
Background technology
The part long bone fracture needs surgical operation therapy.In the operation process, after fracture appears and resets, need temporarily keep the temporary fixed of the reduction of the fracture and steel plate, so that further pedicle screw is finished finally fixing completely.But after the reduction of the fracture and finish final fixing before, fracture and steel plate regular meeting are shifted once more, especially for unstable fracture, to such an extent as to operation is wasted time and energy, surgical result is dissatisfied.
Summary of the invention
For overcoming fracture and the easy problem of displacement once more of steel plate in the long bone fracture therapeutic process, this utility model provides a kind of reduction of the fracture steel plate holder, and this holder can not only temporarily be kept the position of fracture and steel plate, can also carry out the therapeutic compression of fracture end.
For achieving the above object, this utility model adopts following technical proposals:
A kind of reduction of the fracture steel plate holder, comprise adapter, support bar, threaded rod and bone fixation means, threaded rod vertically passes adapter by screw thread, support bar is two, laterally be fixed in the both sides of adapter respectively, the inboard of support bar is that cross section is polygonal slide bar, and the outside is the pressurization threaded rod that has nut spanner, and support bar is provided with slide cartridge; Described bone fixation means is: the mid portion of two metal arms is hinged, and the one end is a clamp-holding hole, and the other end is for stinging the bone tooth; Also be provided with lock pincers device on the bone fixation means; Two metal arm hinged places are provided with the hollow joint, and the hollow parts in hollow joint matches with the shape of slide bar cross section.
The upper end of described threaded rod is provided with spanner, and the lower end flexibly connects a silicagel pad.
The diameter of described pressurization threaded rod cross section is not more than slide bar cross section polygon inscribe diameter of a circle, and the inner core of described slide cartridge matches with the shape of cross section of slide bar.
The cross section of described slide bar can be regular hexagon.
Reduction of the fracture steel plate holder of the present utility model can be kept fracture and the steel plate position after resetting temporarily, avoids fracture and steel plate to be shifted once more, thereby is convenient to the smooth implantation of screw, avoids repeatable operation, reduces wound, saves operating time; Centrality by holder is drawn close, and realizes the pressurization of fracture end, and fracture end is closely contacted, thus the immediate union that helps fracturing.

The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified.
As Fig. 1, Fig. 3 and shown in Figure 5, a kind of reduction of the fracture steel plate holder comprises adapter 11, support bar, threaded rod 10 and bone fixation means.
As shown in Figure 3, threaded rod 10 vertically passes adapter 11 by screw thread, and the upper end of described threaded rod 10 is provided with spanner 9, and spanner 9 passes the through hole of being located at threaded rod 10 upper ends, and spanner 9 is detachable spanner, and the lower end flexibly connects a silicagel pad 12.Threaded rod 10 can move up and down by regulating the relative adapter 11 of screw thread, makes the steel plate 13 that is fixed on silicagel pad 12 belows closely be attached to long bone 14 surfaces, avoids steel plate 13 to be shifted once more, thus carrying out smoothly of helping performing the operation.
As shown in Figure 4, support bar is two metallic rod that structure is identical, laterally be fixed in the both sides of adapter 11 respectively, the inboard of support bar is that cross section is orthohexagonal slide bar 8, the outside is for having the pressurization threaded rod 5 of nut spanner 6, the diameter of pressurization threaded rod 5 cross sections is not more than slide bar 8 cross section regular hexagon inscribe diameter of a circles, support bar is provided with the slide cartridge 7 that its inner core matches with slide bar 8 shape of cross sections, its purpose is to make slide cartridge 7 to horizontally slip on slide bar 8 and pressurization threaded rod 5, swivel nut spanner 6, nut spanner 6 pressurizes by 7 pairs of bone fixation means that are located on the slide bar 8 of slide cartridge, the bone fixation means of both sides is drawn close to the center, thereby realized the pressurization of fracture end.
As shown in Figure 1 and Figure 2, described bone fixation means is: the mid portion of two metal arms is hinged, and the one end is a clamp-holding hole 1, and the other end is for stinging bone tooth 4; Also be provided with lock pincers device 2 on the bone fixation means; Two metal arm hinged places are provided with hollow joint 3, the hollow parts in hollow joint 3 matches with the shape of slide bar 8 cross sections, be that its cross section also is regular hexagon, the structure of positive six shapes can prevent that bone fixation means from rotating in the axial direction, keeps the firmly steady of bone fixation means.Lock pincers device 2 is that two opposite faces are the dentalation long bonding jumper of interlock mutually, is separately fixed on 2 metal arms, and when metal arm clamped long bone 14, lock pincers device 2 fastened, and can keep bone fixation means in a certain position.
Among Fig. 5, the hollow joint 3 of 2 bone fixation means is placed on the hexagon slide bar 8 of support bar.After the reduction of the fracture, the bone tooth 4 of stinging of bone fixation means closely attaches to long bone 14 surfaces, bites the sclerotin of fracture both sides, tightens detachable spanner 9, and silicagel pad 12 is pressed on long bone 14 surfaces with steel plate 13.Two bone fixation means reduction of the fracture steel plate holders and the rectangular structure of long bone, by swivel nut spanner 6 to the inside, the both sides bone fixation means is drawn close to the fracture line 15 at center, thereby realizes the pressurization of fracture end.Steel plate 13 is inserted the appropriate location of long bone 14, tighten detachable spanner 9 downwards, silicagel pad 12 closely is attached to long bone 14 surfaces with steel plate 13, avoids steel plate 13 to be shifted once more, thus carrying out smoothly of helping performing the operation.
