Abstract
The utility model discloses a universal locking bone fracture plate screw system. The universal locking bone fracture plate screw system comprises a bone fracture plate and a screw, wherein the bone fracture plate is provided with a screw hole. The universal locking bone fracture plate screw system further comprises a screw cap provided with external threads, the head of the screw is in an outer spherical shape, a pressing portion pressing the upper side of the head of the screw is arranged at the bottom end of the screw cap, the screw hole is provided internal threads matched with the external threads, and a supporting part supporting the lower side of the head of the screw is arranged at the bottom end of the screw hole. The universal locking bone fracture plate screw system has the advantages of having a large selection range of the implantation direction and being good in locking effect.
Description
Technical field
This utility model relates to a kind of orthopedic medical device, particularly relates to a kind of locking bone fracture plate screw system.
Background technology
For locking bone fracture plate screw system fixing in orthopaedics, mainly lock screw and blade plate, consist of clinically, the angle between lock screw and blade plate is predefined.In order to make the lock screw in implantable bone there is best fixed effect, require the lock screw must be by specific direction implantable bone; Due to the different of damaged portion of fracturing, and the skeletal shape between Different Individual there are differences, therefore in clinical practice, often there is implantation direction and the best inconsistent contradiction of direction of implanting set between lock screw and steel plate in this locking bone fracture plate screw system, affects surgical effect.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of Universal locking fracture bone plate screw system, and the universal lock screw in this system has advantages of that the set direction of implantation scope is large, locking effect good.
For achieving the above object, the technical solution of the utility model is as follows: a kind of Universal locking fracture bone plate screw system, and this system comprises blade plate and screw, and described blade plate is provided with screw hole, and this system also comprises the head of a nail, and the described head of a nail is provided with external screw thread; Described screw head is that ectosphere is planar; Described head of a nail bottom is provided with the compressed part that compresses described screw head upside; Described screw hole is provided with the female thread with described external screw thread coupling, and described screw hole bottom is provided with the supporting part of the described screw head downside of support.
Preferably, described supporting part is that endosphere is planar.
Preferably, the angle of the inclined-plane of described compressed part and described head of a nail axis is 20 °.
The beneficial effect of technical solutions of the utility model is:
1, after the screw hole of screw placement blade plate, the supporting part support screw head downside of screw hole bottom, because screw head is that ectosphere is planar, screw head can be in screw hole universal rotational, the implantation direction of screw can be selected in a larger scope.
2, the screw hole of the head of a nail and blade plate is threaded, and after the head of a nail screws in screw hole, on the compressed part of the head of a nail and screw head, side compression makes the screw locks in place, and locking effect is good.

A kind of concrete structure schematic diagram that Fig. 5-Fig. 7 is the head of a nail described in the disclosed a kind of Universal locking fracture bone plate screw system of this utility model embodiment, wherein Fig. 5 is front view, and Fig. 6 is right view, and Fig. 7 is the enlarged drawing of Fig. 5.
A kind of concrete structure schematic diagram that Fig. 8 and Fig. 9 are the screw hole of the described blade plate of screw placement described in the disclosed a kind of Universal locking fracture bone plate screw system of this utility model embodiment, wherein Fig. 9 is the partial enlarged drawing of Fig. 8.
The structural representation of the specific embodiment that Figure 10 and Figure 11 are the disclosed a kind of Universal locking fracture bone plate screw system of this utility model embodiment, wherein Figure 11 is the partial enlarged drawing of Figure 10.
The specific embodiment
Fig. 1 is to an embodiment who Figure 11 shows that this Universal locking fracture bone plate screw system, and this system comprises blade plate 100, screw 200 and the head of a nail 300.Referring to Fig. 1 to Fig. 3, blade plate 100 is provided with screw hole 101, and this screw hole 101 is provided with female thread 101-2, and these screw hole 101 bottoms are provided with the planar supporting part 101-1 of endosphere.Referring to Fig. 4, screw head 201 is that ectosphere is planar.Referring to Fig. 5 to Fig. 7, the head of a nail 300 is provided with external screw thread 301, these head of a nail 300 bottoms are provided with compressed part 302, and the angle of the inclined-plane of this compressed part 302 and the head of a nail 300 axis is 20 °, and the center of these head of a nail 300 upper surfaces is provided with the inner hexagonal hole 303 for screwing in the head of a nail 300.
Referring to Fig. 8 and Fig. 9, behind screw 200 pedicle screw holes 101, the supporting part 101-1 support screw head downside 201-2 of screw hole 101, screw head 201 can carry out the rotation of certain angle scope in screw hole 101, and then be suitable for adjusting arbitrarily the implantation direction between screw 200 and blade plate 100, finally make the implantation direction that sets between screw 200 and blade plate 100 and best implantation direction consistent.
Referring to Figure 10 and Figure 11, the female thread 101-2 of screw hole 101 and the external screw thread 301 of the head of a nail 300 mate mutually.When the head of a nail 300 screws in screw hole 101, the compressed part 302 of the head of a nail 300 compresses with screw head upside 201-1, makes screw 200 locks in place.
