Description
Technical field
The present invention relates to orthopedic medical device fields, in particular to a kind of bone plate structure.
Background technique
It is directed to the symptom of the long bone fractures such as patient's shin bone, femur, the form medically fixed in advance using bone plate at present
It keeps skeletal stabilization, promote bone healing.The fixed form of bone plate mainly has screw to fix, tired bundle is fixed etc..In order to guarantee
Relative position is stable between bone, avoids generation activity, and bone plate generallys use the higher material of hardness and planform to protect
Fixed effect is demonstrate,proved, while also there is very high stability in human body.With the gradually healing of subjects bones, bone plate is in the later period
It can take out.
But generated for teenager in the treatment of fracture, although can be played well using traditional bone plate in early period
Therapeutic effect, but since teenager is in growth and development quick period, the excessively stable easy limitation bone of bone plate
Normal growth, and then cause teenager's skeleton development asymmetric.
Summary of the invention
The present invention is intended to provide a kind of bone plate structure, to solve in the prior art, the excessively stable limitation bone of bone plate is being just
The problem of being frequently grown.
To achieve the goals above, multiple the present invention provides a kind of bone plate structure, including sliding rail and multiple bones plate
Bone plate is arranged on the slide rail, is connected between two adjacent bones plate by connector, and connector can be when implantation be default
Between after ablation separate two adjacent bones plate.
Further, sliding rail is two disposed in parallel, and multiple bones plate are arranged between two sliding rails.
Further, it is provided with dovetail groove on sliding rail, sliding block compatible with dovetail groove is provided on bone plate.
Further, multiple bones plate include two end plates and at least one connecting plate, and connecting plate is arranged in two end plates
Between, it is connected between end plate and connecting plate by connector.
Further, connecting plate is multiple, is connected between multiple connecting plates by connector.
Further, there are two screw holes, two screw holes to shift to install for setting on connecting plate.
Further, screw hole is counter sink.
Further, the material of connector is degradable biomaterial.
Further, degradable biomaterial is magnesium alloy materials or degradable high polymer material.
Further, the material of bone plate is titanium alloy, ceramics or high molecular material.
It applies the technical scheme of the present invention, connector melts the work for disconnecting two neighboring bone plate after preset time
With such bone plate can be slided with being grown in sliding rail for subjects bones, weakened bone plate structure and grown in subjects bones
Limitation on direction, to avoid the asymmetric problem of teenager's skeleton development.Meanwhile sliding rail still plays bone plate and bone
To certain support fixed function, secondary injury is avoided.
Detailed description of the invention

Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figures 1 to 4, the bone plate structure of the present embodiment includes sliding rail 10 and multiple bones plate 20, multiple synthetisms
Plate 20 is arranged on sliding rail 10, is connected between two adjacent bones plate 20 by connector 30, connector 30 can be implanted into
Ablation separates two adjacent bones plate 20 after preset time.
The degradable biomaterial for being suitable for being implanted into organism, such as magnesium alloy, degradable high score can be selected in connector 30
Sub- material etc., these materials can be dissolved or degrade after a period of time in implantation organism, so that disconnection acts on, make
Bone plate 20 can be free to slide in sliding rail 10.Titanium alloy, ceramics or high molecular material etc. can be selected in the material of bone plate 20
Metastable medical material simultaneously provides for subjects bones at the initial stage of implantation and enough fixes and supports effect.
Using the technical solution of the present embodiment, connector 30 melts after preset time disconnects two neighboring bone plate
20 effect, such bone plate 20 can be slided with being grown in sliding rail 10 for subjects bones, weakened bone plate structure and suffered from
Limitation on person's bone growth direction, to avoid the asymmetric problem of teenager's skeleton development.Meanwhile sliding rail is still to synthetism
Plate 20 and bone play certain support fixed function, avoid secondary injury.
The specific degradation time of connector 30 can be according to the characteristic of the degradable material of concrete application and the body of patient itself
Body situation and sclerotin situation are set.
Preferably, as shown in figure 3, the sliding rail 10 of the present embodiment is two disposed in parallel, multiple settings of bone plate 20 exist
Between two sliding rails 10.It is provided with dovetail groove 11 on sliding rail 10, sliding block compatible with dovetail groove 11 is provided on bone plate 20.
The dovetail groove 11 of sliding rail 10 can also be effectively prevented bone plate 20 and sliding rail in addition to that can limit the moving direction of bone plate 20
10 are detached from, and make bone plate stable structure, guarantee fixed effect.
As shown in Figure 1, the bone plate 20 of the present embodiment includes two end plates 22 and multiple connecting plates 21, the setting of end plate 22 exists
Both ends, connecting plate 21 is arranged between two end plates 22, between two connecting plates 21 between end plate 22 and connecting plate 21, adjacent
Connected by connector 30.The factors such as the quantity of connecting plate 21, the length of end plate 22 can be increased and decreased according to patient's actual conditions,
Make bone plate structure that can provide enough support fixed effects and end plate 22 in subjects bones' growth course
The case where deviating from sliding rail 10.
The side of connecting plate 21 and end plate 22 towards bone is in curved surface, with the compactness between raising and bone；Connecting plate
21 and side of the end plate 22 far from bone it is also in curved surface, it is sharp to reduce with the contact area between increase and surrounding soft tissue
Edge bring sense of discomfort.
In the bone plate structure of the present embodiment, a screw hole 23 is provided on each end plate 22, in each connecting plate
There are two screw holes 23, two screw holes 23 to shift to install for setting on 21.Preferably, screw hole 23 is counter sink, such murices
Head of screw can be hidden in bone plate 20 when in nail implantation bone, reduce head of screw to the thorn of subjects bones surrounding soft tissue
Swash, reduces pain, improves comfort.Sliding rail 10 does not contact directly with bone, will not influence the elongation of bone plate 20, dovetail groove 11
There is certain resistance between bone plate 20, therefore sliding rail 10 will not be skidded off from bone plate 20.
It can be seen from the above description that the above embodiments of the present invention realized the following chievements:
Connector melts the effect for disconnecting two neighboring bone plate after preset time, and such bone plate can be with
Being grown in sliding rail for subjects bones is slided, and weakens limitation of the bone plate structure in subjects bones' direction of growth, to avoid
The asymmetric problem of teenager's skeleton development.Meanwhile sliding rail still plays certain support fixed function to bone plate and bone,
Avoid secondary injury.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
