In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it includes bone plate ontology, the locking of φ 5.0 Screw, 3.5 lock screw of φ；The bone plate ontology includes head, long plate body, short slab body；Long plate body, short slab body are set side by side In the lower section on head；Long plate body, the thickness of short slab body are gradually thinning by top terminad；Head is equipped with two rows of lock screws Hole, upper row be three 5.0 screw holes of φ, lower row be two 3.5 screw holes of φ and 5.0 screw hole of φ, And this 5.0 screw hole of φ is located between two φ, 3.5 screw hole；Four 5.0 screw holes of φ and two φ 3.5 lock The longitudinal axis for determining screw hole intersects at a point；It is locked there are four being set on long plate body along the φ 5.0 of long slab body length directional spreding Screw hole；Along 3.5 screw hole of φ of short slab body length directional spreding there are three being set on short slab body.

Further, 5.0 screw hole of φ and 5.0 lock screw of φ are cooperatively connected；

Further, 3.5 screw hole of φ and 3.5 lock screw of φ are cooperatively connected；

Further, 5.0 lock screw of φ, 3.5 lock screw entire body screw thread of φ；

Further, the hole column pitch of 5.0 screw hole of φ is greater than 3.5 screw hole of φ on short slab body on long plate body Hole column pitch.

After adopting the above structure, the utility model has the beneficial effect that tibial plateau osteotomy described in the utility model is orthopedic Locking bone fracture plate, stability is good, promotes knitting, using 5.0 lock screw of φ, 3.5 lock screw of φ, avoidable bone nail is locked Interference effect each other afterwards improves operation accuracy, validity, and have structure is simple, setting rationally, cost of manufacture it is low etc. Advantage.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, is also possible to obtain other drawings based on these drawings.

Fig. 1 is the structural schematic diagram of the utility model.

Description of symbols:

1, long plate body；2,5.0 lock screw of φ；3, head；4,3.5 lock screw of φ；5, short slab body.

Specific embodiment

With reference to the accompanying drawing, the utility model is further described.

Referring to shown in Fig. 1, present embodiment the technical solution adopted is that: it includes that bone plate ontology, φ 5.0 are locked Screw 2,3.5 lock screw 4 of φ；The bone plate ontology includes head 3, long plate body 1, short slab body 5；Long plate body 1, short slab body 5 are located at the lower section on head 3 side by side；Long plate body 1, the thickness of short slab body 5 are gradually thinning by top terminad；Head 3 is equipped with two Screw hole is arranged, upper row is three 5.0 screw holes of φ, and lower row is that two 3.5 screw holes of φ and a φ 5.0 lock Determine screw hole, and this 5.0 screw hole of φ is located between two φ, 3.5 screw hole；Four 5.0 screw holes of φ and two The longitudinal axis of a 3.5 screw hole of φ intersects at a point；Along long slab body length directional spreding there are four being set on long plate body 1 5.0 screw hole of φ；Along 3.5 screw hole of φ of short slab body length directional spreding there are three being set on short slab body 5.

5.0 screw hole of φ and 5.0 lock screw 2 of φ is cooperatively connected；

3.5 screw hole of φ and 3.5 lock screw 4 of φ is cooperatively connected；

5.0 lock screw 2 of φ, 3.5 lock screw of φ, 4 entire body screw thread；

The hole column pitch of 5.0 screw hole of φ is greater than the hole location of 3.5 screw hole of φ on short slab body 5 on long plate body 1 Spacing.

After adopting the above scheme, the orthopedic locking bone fracture plate of tibial plateau osteotomy described in present embodiment, have with Lower advantage:

1, four 5.0 screw holes of φ on head 3 and the longitudinal axis of two 3.5 screw holes of φ intersect at one Point forms angulation and stablizes, makes to form strong fixation between bone plate and bone, to keep knitting more quick；

2, it is designed using 5.0 lock screw 2 of φ, the big tingle of 3.5 lock screw of φ 4, takes into account bone plate hole location and bone hole The comprehensive consideration of both holes intensity, while interference effect each other after effectively screw being avoided to lock；

3, it is designed by hole location on long plate body 1, short slab body 5, avoids contradicting each other for bone screw holes and gap position, simultaneously After reduction bone nail is locked, there is a situation where intersect to pass through bone notch；

4, long plate body 1, the thickness of short slab body 5 are gradually thinning by top terminad, and the end of bone plate is facilitated to be inserted into.

The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope should all cover in the scope of the claims of the utility model.
