Description
Technical field
The utility model relates to a kind of steel plate screw system with universal lock function, is a kind of surgical implants system for fixed reset after human limb fracture.
Background technology
Be soft flexible and plastic originally when skeleton is just formed, along with the growth at age, the composition of cartilage is gradually few, and the composition of os osseum becomes many gradually, and fracture starts easily to occur.
Locking steel plate screw system clinically for orthopaedics internal fixtion is formed primarily of lock screw and steel plate, and in locking steel plate screw system, the angle between lock screw and steel plate presets.In order to make the lock screw of implant 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, often there is implantation direction set between lock screw and steel plate and implant the inconsistent contradiction in direction with best in this locking steel plate screw system, affects surgical effect.
Summary of the invention
This utility model object provides a kind of steel plate screw system with universal lock function for above-mentioned weak point.A kind of steel plate screw system design with universal lock function is reasonable, implants set direction scope large, the advantages such as locking effect is good.Can change to the relative position between lock screw and steel plate in art, when ensure that operation, most suitable implantation direction can be selected according to the Bone fracture characteristics of Different Individual.
A kind of steel plate screw system with universal lock function takes following technical scheme to realize:
A kind of steel plate screw system with universal lock function comprises steel plate and lock screw composition.Described steel plate is provided with screwed hole; The screwed hole that steel plate is arranged is conical screw hole.
Described lock screw comprises lock-screw thread rod part and screw head.Described screw head is provided with universal groove.Described universal groove is for be provided with some cannelures at screw head.Screw head periphery is provided with external screw thread, and steel plate is provided with corresponding threaded holes and closes.
The external screw thread arranged in screw head periphery is tapered thread.
Operation principle
When a kind of steel plate screw system with universal lock function is for performing the operation, according to the Bone fracture characteristics of Different Individual, select best implantation direction, fracture is loaded onto the steel plate being threaded hole, utilize Universal drill guider and drill bit on bone, accomplish fluently the prebored hole in the most applicable implantation direction, by bottle opener by the lock-screw with universal groove, utilize the principle of screw thread of staggering, by lock screw at variable-angle internal fixtion in steel plate screwed hole.Now screw enters the direction of fracture for operation optimum orientation.
A kind of steel plate screw system advantage with universal lock function:
A kind of steel plate screw system design with universal lock function is reasonable, structure is simple, because screw head is provided with universal groove, can solve implantation direction set between the lock screw of clinical middle locking steel plate screw system existence and steel plate and implanted the inconsistent contradiction in direction with best, when determining operation, most suitable implantation direction can have been selected according to the Bone fracture characteristics of Different Individual.
Accompanying drawing explanation
Below with reference to accompanying drawing, the utility model is described in further detail:
Fig. 1 a kind ofly has lock screw schematic diagram in the steel plate screw system of universal lock function.
Fig. 2 a kind ofly has the steel plate screw system of universal lock function and is arranged on fracture schematic diagram.
In figure, labelling lists as follows:
1, lock-screw thread rod part, 2, screw head, 3, universal groove, 4, steel plate, 5, screwed hole, 6, screw driver, 7, bone, 8, external screw thread.
Detailed description of the invention
With reference to accompanying drawing 1,2, a kind of steel plate screw system with universal lock function comprises steel plate 4 and lock screw composition.Described steel plate 4 is provided with screwed hole 5; The screwed hole 5 that steel plate 4 is arranged is conical screw hole.
Described lock screw comprises lock-screw thread rod part 1 and screw head 2.Described screw head 2 is provided with universal groove 3.Described universal groove 3 is for be provided with some cannelures at screw head.Screw head 2 periphery is provided with external screw thread 8, and steel plate 4 is provided with corresponding threaded holes and closes.
The external screw thread arranged in screw head 2 periphery is tapered thread.
When a kind of steel plate screw system with universal lock function is for performing the operation, select best implantation direction, fracture is loaded onto the steel plate 4 with steel plate screwed hole 5, drill bit best implantation on direction on bone 7 is utilized to accomplish fluently prebored hole, by screw driver 6, lock-screw thread rod part 1 is screwed in bone 7 through steel plate screwed hole 5, continue to turn screw driver 6, utilize the screw thread of the steel plate screwed hole 5 that to stagger with the universal groove 3 of the screw head 2 of universal groove, screw head 2 with universal groove is tightened with steel plate screwed hole 5 is angled, realize lock-screw the best and implant direction.
