Abstract

The utility model relates to a distal radius universal locking bone plate which comprises a bone plate, a plurality of radial screw holes, a plurality of ulnar screw holes, a plurality of pinholes, and a plurality of combining holes, wherein the top of the bone plate is in a reversed triangle shape and the middle-lower portion of the bone plate is in a strip shape, the plurality of radial screw holes are formed in the upper right end of the bone plate and used for fixing with a radial column through screws, the ulnar screw holes are formed in the upper left end of the bone plate and used for fixing with a middle column through screws, the plurality of pinholes are formed in the middle of the bone plate and used for temporarily fixing the bone plate, and the plurality of combining holes are formed in the middle-lower portion of the bone plate and used for adjustment of bone plate position. The distal radius universal locking bone plate is simple in structure. The utilization of a universal locking technology enables the track of deviation between a locking screw deviate and a bone plate middle shaft to be flexible, so that a best effect of fixation of special fracture fragments can be achieved.

Description

The distal radius Universal locking fracture bone plate

Technical field

This utility model relates to a kind of blade plate, specifically a kind of distal radius Universal locking fracture bone plate.

Background technology

The gradient of the bone screw of existing blade plate can only be by plate hole the gradient of female thread determine, can not do adjusting; And some special fractures piece when inserting screw with existing blade plate, can't guarantee the optimum efficiency of support joint face.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of simple in structure, and the distal radius Universal locking fracture bone plate of the lock screw of different angulations can be provided at the blade plate head.

In order to address the above problem, this utility model provides a kind of distal radius Universal locking fracture bone plate, comprise: the top is the blade plate that handstand triangle and middle and lower part are strip, be located at a plurality of oar side screw holes that be used for to adopt screw and oar lateral column to fix of the upper right side of blade plate, be located at a plurality of ulnar side screw holes that be used for to adopt screw and intermediolateral column to fix of blade plate left upper end, be located at a plurality of pin holes that are used for temporary fixed this blade plate at blade plate middle part, be located at a plurality of combined holes that are used for blade plate position adjustment of the middle and lower part of blade plate.

The edge of described blade plate adopts high polishing, can near the palmar ridge, reduce soft tissue irritation.

Be distributed with the decile groove on described oar side screw hole and ulnar side screw hole, be suitable for making the screw that is mated to swing angulation in the abaxial all directions, the convenient latch-up structure that produces improves angulation stability; The spherical head of described screw is provided with screw thread.

The top of described blade plate and middle and lower part adopt the twin columns structure to be connected, and make blade plate in stable, have reduced and the contacting of bone, and have limited the blood vessel wound.

This utility model has positive effect with respect to prior art: distal radius Universal locking fracture bone plate of the present utility model is simple in structure, use the track motility that the universal lock technology can provide lock screw to depart from the blade plate axis, thereby reach the fixing optimum efficiency to the special fractures piece.

Description of drawings

For content of the present utility model is more likely to be clearly understood, below the specific embodiment and by reference to the accompanying drawings of basis, this utility model is described in further detail, wherein:

Fig. 1 is the structure chart of distal radius Universal locking fracture bone plate of the present utility model.

The specific embodiment

See Fig. 1, the distal radius Universal locking fracture bone plate of the present embodiment, comprise: the top is the blade plate that handstand triangle and middle and lower part are strip, be located at four oarside screw holes 1 that be used for to adopt screw and oar lateral column to fix of the upper right side of blade plate, be located at three ulnarside screw holes 2 that be used for to adopt screw and intermediolateral column to fix of blade plate left upper end, be located at twopin holes 3 that are used for temporary fixed blade plate at blade plate middle part, be located at five combinedholes 4 that are used for blade plate position adjustment of the middle and lower part of blade plate.

The edge of described blade plate adopts high polishing, can near the palmar ridge, reduce soft tissue irritation.

Be distributed with the decile groove on described oarside screw hole 1 and ulnarside screw hole 2, be suitable for making the screw that is mated to swing angulation in the abaxial all directions, the convenient latch-up structure that produces improves angulation stability; The spherical head of described screw is provided with screw thread, to coordinate with described oarside screw hole 1 and ulnarside screw hole 2.

The top of described blade plate and middle and lower part adopt the twin columns structure to be connected, and make blade plate in stable, have reduced and the contacting of bone, and have limited the blood vessel wound.

The track motility that the universal lock technology of this distal radius Universal locking fracture bone plate can provide lock screw to depart from the blade plate axis, thus reach fixing optimum efficiency to the special fractures piece.

Obviously, above-described embodiment is only for this utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among protection domain of the present utility model.
