Description
Technical field
This application involves the new device and technology of first aid and rehabilitation, the locking compress hole of more particularly to a kind of bone plate.
Background technology
Currently used metal bone fracture plate is divided into two classes, and one kind is conventional pressurized bone plate, another kind of to be locked out steel plate.It is general
Logical pressurized bone plate which is provided with pressurization hole, can carry out loaded reset to fracture site, coordinate the cortex bone or spongiosa of round end
Bone screws use, and are pressed on bone surface by screw, reach by the frictional force between bone and steel plate and be fixedly secured, with load
Cyclically-varying, screw gradually loosens, and frictional force reduces, and steel plate is caused to loosen, and it is unstable then to occur fracture, finally
Unstable internal fixation can occur.For metaphysis or sclerotin have it is loose in the case of, to keep screw always well it is fixed very
Difficulty, therefore being fixedly secured for fracture is difficult to maintain.Meanwhile the compressing that the fixation of conventional compression steel plate generates bone, it affects
Periosteum and the blood of fracture region fortune.Locking steel plate uses external fixator biomethanics settled principle, which is provided with threaded locking
Hole, by coordinating with lock screw, steel plate is integral with screw shaped, and stable angle is formed between screw and steel plate, allows
It is not contacted completely with bone face when placing locking steel plate, the compressing transported to periosteum and blood is small.It does not need to produce between steel plate and bone
Raw frictional force, from the point of view of biomethanics, should be known as internal fixation device.
In order to make locking steel plate that can also carry out loaded reset, the pressing mechanism of independence or dependent can be generally set thereon.Mesh
Former mode is to set lock hole and pressurization hole respectively on the steel plate, but due to lock hole on one block of steel plate and the position in pressurization hole
It is fixed, differ and surely fully meet the demand of practical surgical, may be lock hole in the position for needing to pressurize, and needing
The position of locking may be pressurization hole, and many inconvenience are brought to doctor.Another way is to set a kind of pressurization lock on the steel plate
Determine combined hole, than the more typical pass (patent No. 00818648) represented with 8 word Kong Wei, which is overlapped by two holes and formed,
Holes is again relatively independent, and in 8-shaped, the not threaded hole of a part can accommodate skin nail or pine nail carries out loaded reset, another portion
Point threaded hole is used cooperatively with lock screw, is realized and is locked, and longitudinal size is larger on the steel plate for this kind of pass its through-hole, and one
Determine to affect the intensity of steel plate in degree.So it needs to propose to improve.
Invention content
The purpose of the present invention is to provide a kind of locking compress hole of bone plate, to overcome deficiency of the prior art.
To achieve the above object, the present invention provides following technical solution：
The embodiment of the present application discloses a kind of locking compress hole of bone plate, and the side far from bone face is equipped with head successively
Pressurization hole, lock hole and the eccentric orfice that tail connects, the pressurization hole are trough type ball, and the lock hole is tapered thread
Hole, the eccentric orfice are ball, and the center line in the pressurization hole is overlapped with the center line of the lock hole, in the lock hole
Heart line and any diameter of the eccentric orfice are misaligned.
Preferably, in the locking compress hole of above-mentioned bone plate, the lock hole is close to the one end in the pressurization hole
Diameter is more than diameter of the lock hole close to one end of the eccentric orfice, and the taper of the lock hole is 20 °.
Preferably, in the locking compress hole of above-mentioned bone plate, double thread is machined in the lock hole.
Preferably, in the locking compress hole of above-mentioned bone plate, the both ends of the lock hole and the pressurization hole and inclined
Distinguish rounding off in heart hole.
Compared with prior art, the advantage of the invention is that：The locking compress hole of bone plate of the present invention is using peculiar
Form, middle part locking bore portion is machined with double thread, and have 20 ° of tapers, is length at the top of pressurization hole for common lock screw
Groove profile ball, forcing screw can be implanted into the range of certain angle, according to actual conditions choice direction during use.Under lock hole
Portion is an eccentric ball, for increasing angle during forcing screw implantation.
Description of the drawings
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or it will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments described in application, for those of ordinary skill in the art, without creative efforts,
It can also be obtained according to these attached drawings other attached drawings.
Fig. 1 show the structure diagram in the locking compress hole of bone plate in the specific embodiment of the invention.
Fig. 2 show the use schematic diagram in the locking compress hole of bone plate in the specific embodiment of the invention.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, detailed retouch is carried out to the technical solution in the embodiment of the present invention
It states, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, shall fall within the protection scope of the present invention.
Join shown in Fig. 1 and Fig. 2, the locking compress hole of the bone plate in the present embodiment, the side far from bone face is set successively
There are end to end pressurization hole 10, lock hole 20 and eccentric orfice 30, pressurization hole 10 is trough type ball, and lock hole 20 is taper
Threaded hole, eccentric orfice 30 are ball, and the center line in pressurization hole 10 is overlapped with the center line of lock hole 20, the center line of lock hole 20
It is misaligned with any diameter of eccentric orfice 30.
In the technical solution, using peculiar form, middle part lock hole 20 is in the locking compress hole of bone plate of the present invention
Conical screw hole, for common lock screw 1, pressurization is trough type ball at the top of hole, and forcing screw can be in the model of certain angle
