Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of universal locking device of locking bone fracture plate.
Background technology
The internal fixation system of locking bone fracture plate and bone screw has used a lot of year clinically, is to treat the most frequently used internal fixation material of fracture at present.Tradition locking bone fracture plate system is provided with screw hole on steel plate, by assembling with the screw with conical external screw thread, and the internal fixation system that composition angulation is stable.But the method also has its fraud, locking screw thread cannot adjusting angle, and especially fracture site is when metaphysis, and screw cannot fix free ossiculum block, clinically troublesome poeration during process, thus affects surgical quality.For this reason, there has been proposed bulletin CN101999927A " blade plate universal lock pressue device ", its structure is provided with long slide opening on blade plate body, in long slide opening, locking sliding block is installed, locking sliding block is provided with cone screw hole, and cone screw hole, built with cone-head screw, is characterized in that: the two sides of long slide opening are intrados, the two sides shape of locking sliding block is the extrados adapted with it, and the middle part of locking sliding block is with concave indentation.But there is following disadvantage in above-mentioned technical scheme: one is because long slide opening can only make locking sliding block and cone-head screw swing adjustment, and can not make adjustments at three-dimensional, namely need can not make adjustments as three-dimensional according to performing the operation; Two is because the two sides of long slide opening are intrados, the two sides shape of locking sliding block is the extrados adapted with it, so when cone-head screw is when frequently stressed, slip can be produced between cambered surface, position between the long slide opening of blade plate body and locking sliding block, poor stability, therefore can affect the locking fracture quality of blade plate; Three is first can only fix in long slide opening at the fracture site of human body the blade plate body being provided with locking sliding block, could in locking sliding block spinning cone-head screw, this makes troubles to operation.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned the deficiencies in the prior art, and provide a kind of universal locking device of locking bone fracture plate, it has the following advantages: one is in the angle that can regulate bone screw at three-dimensional; Two is both can in the first fixation bone fracture plate of fracture site in operation, the bone screw that spins is filled again from the screw that the Universal lock of blade plate is smashed, also first bone screw can be fixed at fracture site, the universal snap close being provided with screw screwed in blade plate is filled again on the threaded head of a nail of system, again in fracture site fixation bone fracture plate, thus the operation that can conveniently perform the operation; Three is screws that blade plate is provided with fixing universal snap close, can fixedly secure the universal snap close in blade plate with finger spiral shell head.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of universal locking device of locking bone fracture plate, comprise blade plate, bone screw, its main points are that blade plate is provided with spherical pore, be provided with wall glomeration and spherical pore in spherical pore to match the universal snap close rotated, Universal lock is smashed and is provided with screw, and the head of a nail outer wall of bone screw is shaped with the screw thread screwed that to match with screw; Universal snap close is provided with cross open groove, the degree of depth of open slot is greater than the radius of universal snap close, Universal lock fastener is made to have enough elasticity, when Universal lock is buckled in the spherical pore loaded in blade plate, rely on outside pressure, Universal lock is smashed and to be loaded after top can be drawn in spherical pore and still flick glomeration, can do three-dimensional rotation at spherical pore; Blade plate is provided with the positioning screw hole of fixing universal snap close.
As preferably, the screw thread that the described head of a nail outer wall connecing bone screw is shaped with is tapered thread, is also conical bolt hole with the match screw of the universal snap close screwed of screw thread.
The beneficial effects of the utility model: one is the angle that can regulate bone screw at three-dimensional, overcome prior art bone screw can only swing regulate disadvantage; Two is both can in the first fixation bone fracture plate of fracture site in operation, the bone screw that spins is filled again from the screw that the Universal lock of blade plate is smashed, also first bone screw can be fixed at fracture site, Universal lock is buckled in the spherical pore of blade plate and overturns 180 °, the universal snap close being provided with screw screwed in blade plate is filled again on the threaded head of a nail of system, again in fracture site fixation bone fracture plate, thus the operation that can conveniently perform the operation; Three is positioning screw holes that blade plate is provided with fixing universal snap close, can fixedly secure the universal snap close in blade plate with finger spiral shell head.
