Description
Technical field
A kind of external bone-knitting device is the utility model is related to, specifically a kind of external synthetism dress of macromolecule universal lock
Put.
Background technology
Bone-knitting device of the prior art also has the following disadvantages：On the one hand, while fixing bone, because synthetism fills
It is development in itself to put, and have impact on the observation to the reduction of the fracture and healing effect；On the other hand, the outer fixed bone-knitting device of tradition
Incisura is high, influences patient and normally wears the clothes trousers, walking with load.
In addition, the fixed-direction of the screw of traditional bone-knitting device is single, it is impossible to is flexibly adjusted according to patients with fractures's situation
Angle.
In view of the above-mentioned problems, it is necessary to develop a kind of novel external bone-knitting device.
Utility model content
The utility model is primarily to solving existing bone-knitting device of the prior art influences the observation reduction of the fracture and be cured
The problem of fixed-direction of conjunction effect and screw is single.
The utility model is a kind of external bone-knitting device of macromolecule universal lock, including bone plate, on bone plate
Multiple lock holes and the metallic screw being engaged with lock hole, it is characterised in that：The bone plate is by nonvisualized macromolecule material
Material is made, and the lock hole is made up of round platform hole, internal thread hole and cylindrical hole three parts, and the head of screw of the metallic screw is ball
Shape is lacked, can be swung in cylindrical hole internal rotation；The lock hole is also equipped with the locking tail cap being engaged with the internal thread of internal thread hole,
The lower surface of the locking tail cap is provided with groove, and when locking tail cap and internal thread hole screws, metallic screw is also fixed.
Further, the material of the bone plate is polyether-ether-ketone.
Further, the diameter of the cylindrical hole is less than the diameter of internal thread hole.
Further, external screw thread is carved with the outer surface of the head of screw of the metallic screw, is carved on the inwall of the cylindrical hole
There is the external screw thread being engaged with external screw thread.
The beneficial effects of the utility model and feature are：1. knot hone lamella is made up of nonvisualized material, do not influence to fracture
Reset and the observation of healing effect；2. relatively conventional external bone plate incisura is low, patient can normally wear the clothes trousers, and bear a heavy burden row
Walk；3. freely-increased/decreased the number of screws, more screws, multi-angle are fixed, stability is strong；Release fracture is faced juxta-articular to greatest extent
Function；

Embodiment
The utility model is further described below in conjunction with the accompanying drawings：
As shown in Figures 1 and 2, a kind of external bone-knitting device of macromolecule universal lock, including bone plate 2, positioned at bone plate
On multiple lock holes 1 and the metallic screw 3 that is engaged with lock hole；Wherein, the bone plate 2 is by nonvisualized macromolecule material
Material is made, and the material of the bone plate 2 is preferably the high polymer material polyether-ether-ketone that do not develop of intensity and hardness close to steel plate, is connect
Hone lamella 2 is made into close to skeleton dissection form, is connected, realized to fracture with metallic screw 3 by lock hole 1 and locking tail cap 4
Fixation.
The lock hole 1 is made up of round platform hole 11, internal thread hole 12 and the three parts of cylindrical hole 13, when the cylindrical hole 13
Diameter design is the diameter less than internal thread hole 12, can obtain preferable fixed effect.
As shown in Figures 3 and 4, the head of screw of the metallic screw 3 is segment-shaped, can be swung in the internal rotation of cylindrical hole 13,
The fixed angle of metallic screw 3 is adjusted flexibly；The lock hole 1 is also equipped with matching with the internal thread of internal thread hole 12
The locking tail cap 4 of conjunction, the lower surface of the locking tail cap 4 is provided with groove 41, when locking tail cap 4 and internal thread hole 12 screws,
Metallic screw 3 is also fixed.
Fig. 5 illustrates another form of metallic screw, and now the outer surface of the head of screw of metallic screw 3 is carved with and cylinder
The external screw thread 31 that hole 12 is engaged, tail cap 4 can need not be locked with regard to fixation bone fracture plate 2, this spiral shell can be played a part of during use
Follow closely for needing metallic screw 3 and occasion during 2 perpendicular positioning of bone plate.
It in actual use, can be used cooperatively using multiple bones plate, to reach the effect that more flat and stereos are fixed, enhanced
Stability, the influence to fracture site blood supply can be also reduced to greatest extent.
The present apparatus meets early stage strong fixation, and late period biology is fixed, there is provided compression stimulates, and promotes fracture quick more
Close, be not concerned about fixing postoperative infection, the treatment available for internal fixation postoperative infection eliminates without waiting for swelling, can at any time fix, subtract
Few patient suffering, if resetted dissatisfied, also adjustable and simple to operate.
