Description
Technical field
The present invention relates to technical field of medical instruments, be specially a kind of can the blade plate of universal lock.
Background technology
Form primarily of lock screw and steel plate for orthopaedics internal fixtion locking bone fracture plate clinically, we are referred to as locking steel plate screw device.In locking steel plate screw device, the angle between lock screw and steel plate is pre-set.But in order to make the lock screw in implantable bone have best fixed effect, then require that lock screw must by the implantable bone of specific direction, due to the different of damaged portion of fracturing, and the skeletal shape between Different Individual there are differences, therefore in clinical practice, existing locking steel plate screw system often there is implantation direction set between lock screw and steel plate and the best implants the inconsistent contradiction in direction, greatly have impact on surgical effect, also reduce the success rate of operation, and existing locking steel plate screw device roughly has two kinds of structures, one is that pressurization hole independently separates separately with lock hole, another kind is that pressurization hole and lock hole link together, namely through hole is by pressurizeing hole and lock hole part is overlapping forms, namely the pressurize center of clearing end in hole does not overlap with the center of lock hole, although the pressurization hole of the blade plate of this kind of structure and lock hole link together, but its pressurization is independently with lock function, therefore thus become impracticable, in clinical practice, in plate fixation process, position due to lockplate can not adjust or the attaching of blade plate not strong, therefore the success rate of operation is also reduced.
Summary of the invention
The object of the present invention is to provide a kind of can the blade plate of universal lock, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme: a kind of can the blade plate of universal lock, comprise lockplate, described lockplate is welded to each other by two locking columns and forms, described lockplate is disposed with universal locking device from left to right, temporary fixed kirschner pin hole for lockplate and the LCP lengthening combined hole for the adjustment of lockplate position, the bottom of described lockplate is provided with for increasing blood circulation, urge the arcuate groove into bone growth, described universal locking device comprises Universal lock fixed ring, lock hole, fin, accommodation space and screw hole, described Universal lock fixed ring is annular, the inwall of described Universal lock fixed ring is provided with female thread, the outer wall of described lock hole is provided with external screw thread, described Universal lock fixed ring and lock hole to be cooperatively interacted with external screw thread by female thread and are fixedly connected with, described fin is arranged on the inwall of lock hole, described fin is arc-shaped, the center of described fin arranges and is used for screw hole hard-wired with screw fit, gap between described screw hole and fin forms accommodation space.
Preferably, described universal locking device can be provided with 4 to 6.
Preferably, described fin and described screw hole are formed in one structure, and the thickness of fin is increased to outside gradually by inner side.
Preferably, described fin has four, and four fins are circumferentially around the outside being arranged on screw hole.
Preferably, the both sides of described lockplate are the circular arc camber of high polishing.
Preferably, the degree of depth of described arcuate groove can be 0.1 to 0.5mm.
Preferably, described LCP lengthens the length of combined hole can be 0.3 to 0.8mm.
Compared with prior art, the invention has the beneficial effects as follows: this can the blade plate of universal lock, structure is simple, complete pre-fix by arranging LCP lengthening combined hole and kirschner pin hole before fixing, this blade plate can adjust arbitrarily the implantation direction between screw and lockplate, and it has good attaching, better can carry out the fixing of fracture site, blood circulation can be increased by arranging arcuate groove, urge into bone growth, this blade plate is made to have good attaching, itself and surface of bone are had and good mates effect of fitting, both for fracture provides the effect of reset, pressurization can be produced again to sclerite, accelerate the rehabilitation speed of patient, both sides due to lockplate are the circular arc camber of high polishing, make this blade plate can in the process of fishplate bar, reduce the stimulation of soft tissue, this can the blade plate of universal lock easy to use, locking effect is good.
