Abstract
The invention discloses an orthopaedic implant locking elastic bone fracture plate and belongs to medical apparatuses. The orthopaedic implant locking elastic bone fracture plate comprises a bone fracture plate, wherein a locking hole is formed in the bone fracture plate. The orthopaedic implant locking elastic bone fracture plate is characterized in that: the locking hole in the bone fracture plate is a taper thread hole; a screw matched with the taper thread hole is a taper screw; the taper thread hole and the taper screw are connected through taper screw threads; and slots are formed in the two sides of the taper thread hole. After the screw and the bone fracture plate are connected, an elastic effect is achieved between the screw and the bone fracture plate. Because the taper screw thread connection is adopted, the slots are formed in the two sides of the taper screw hole, and the elastic effect is achieved between the screw and the bone fracture plate, the elastic modulus of the traditional implant material can be compensated, the fatigue resistance of a system can be improved, the corrosion of a screw clearance can be reduced, and the bone fracture plate has a very good effect on the promotion of the healing and the rehabilitation of a bone fracture. The orthopaedic implant locking elastic bone fracture plate is reasonable in structure, simple in manufacture and ideal in effect.
Description
Technical field
The invention belongs to medical mechanical domain, specifically is a kind of orthopaedics implant locking elastic bone plate.
Background technology
Existing orthopaedics implant locking blade plate generally adopts higher titanium alloy of elastic modelling quantity and stainless steel material; Lock hole is arranged on the locking bone fracture plate, and lock hole and bone screw form and are rigidly connected, in the bone-setting treatment of this connection; Early stage, the system resilience effect was undesirable; There is stress-shielding effect in later stage, and in fracture healing process, system's fatigue resistance is lower; And, be unfavorable for union of fracture and rehabilitation because lock hole is connected the easy generation corrosion in gap between rear thread with screw.
Summary of the invention
The objective of the invention is deficiency, a kind of better orthopaedics implant locking elastic bone plate of more reasonable structure, effect that adopts taper thread band elasticity hole slot is provided to prior art.
Technical scheme of the present invention is: a kind of orthopaedics implant locking elastic bone plate; Comprise blade plate, lock hole is arranged on the blade plate, it is characterized in that: the lock hole on the blade plate is the taper thread hole; Matching used with it screw is the awl screw; Both connect through the taper thread hole, have hole slot in both sides, taper thread hole, when producing buoyancy effect between the nail-plate after screw and the blade plate connection.
The invention has the beneficial effects as follows: the present invention is owing to adopted the taper thread connection; And the elasticity hole slot is set in both sides, taper thread hole; Produce buoyancy effect between the plate nail, can remedy the elastic modelling quantity of existing implant material, improve system's fatigue resistance; And can reduce the corrosion of thread pitch, to promoting union of fracture and rehabilitation good effect is arranged.The present invention is rational in infrastructure, makes simple, satisfactory for result.

Fig. 2 is screwed hole and the hole slot sketch map of Fig. 1 embodiment.
Fig. 3 is screwed hole and the hole slot sketch map of another kind of embodiment.
Fig. 4 is screwed hole and the hole slot sketch map of another embodiment.
The specific embodiment
Like Fig. 1,2 illustrated embodiments, a kind of orthopaedics implant locking elastic bone plate comprises blade plate 1; Lock hole 3 is arranged on the blade plate 1; It is characterized in that: the lock hole 3 on the blade plate 1 is the taper thread hole, and matching used with it screw 2 is the awl screw, and both connect through the taper thread hole; Have hole slot 4 in both sides, taper thread hole, when producing buoyancy effect between the nail-plate after screw 2 and blade plate 1 connection.
The hole slot 4 of both sides, taper thread of the present invention hole is can width different in size, and hole slot 4 embodiment illustrated in fig. 2 is an elongated shape, and Fig. 3, Fig. 4 are the hole slot of two kinds of broads.
