Abstract
The utility model discloses a bone plate with double-thread locking and pressurization holes shaped like a Chinese character 'ba'. The bone plate comprises a bone plate body and a plurality of screw holes formed in the bone plate body, wherein the screw holes are the double-thread locking and pressurization holes. The two ends of each screw hole are respectively provided with internal threads with the taper of 20 degrees. The width of the joint of each screw hole shaped like the Chinese character 'ba' is larger than the diameter of a screw connected into the screw hole. According to the bone plate with the double-thread locking and pressurization holes shaped like the Chinese character 'ba', more fixing methods are integrated in one structure for various complex therapies, the taper of the threads at each end of each screw hole is 20 degrees, the two ends of each screw hole have locking functions respectively, and any side can be locked according to the clinical needs; the two ends of each hole has the pressurization function and the universal pressurization function, the maximum longitudinal included angle between the screws is 80 degrees, the maximum transverse included angle between the screws is 10 degrees, any end can be selected for conducting pressurization, the directions of the screws can be adjusted according to the clinical needs, and therefore the operation difficulty is lowered, and operation quality and the therapeutic effect are improved.
Description
Technical field
This utility model belongs to the technical field of orthopaedic medical treatment operating theater instruments, relates to a kind of blade plate with the two thread lock pressurization of Eight characters hole.
Background technology
At present, the important means that steel plate screw osteopathy is fractures.Locked pressurized bone plate is to treat at present the most frequently used internal fixation apparatus of fracture both at home and abroad, and existing locked pressurized bone plate roughly has two kinds of structures, and one is that pressurization hole and lock hole are independent separately, separately; Another kind is that pressurization hole and lock hole link together, be through hole by pressurizeing hole and lock hole part is overlapping forms, the pressurize center of clearing end and the center of lock hole in hole do not overlap, although pressurization hole and the lock hole of the blade plate of this kind of structure link together, but its pressurization is independently with lock function, needs first to pressurize with ball screw, then in other lock hole, locks by lock screw, finally ball screw is taken out, can lock by lock screw as required.The blade plate of these two kinds of structures all needs first to pressurize with ball screw, and then lock by lock screw, pressurization separates and carries out with locking, and screw orientation is unadjustable, or can adjustment screw direction, but without pressurization effect, troublesome poeration caused, impact operation quality, operating time is long.
Utility model content
This utility model is exactly in order to solve above-mentioned the problems of the prior art, and a kind of two ends locking that hole both can be provided is provided, again can two ends pressurization and the blade plate with the two thread lock pressurization of Eight characters hole of universal pressurization.
In order to achieve the above object, this utility model adopts following technical scheme:
The blade plate with the two thread lock pressurization of Eight characters hole of the present utility model, comprises blade plate main body and is arranged on the multiple screw holes in blade plate main body; Screw hole is the two thread lock pressurization of splayed hole.
It is the female thread of 20 ° that the two ends of described screw hole are tapering, and is provided with two pcketing that add.
The width of described screw hole splayed junction is greater than the diameter that is connected to the screw in screw hole.
Advantage and the good effect that the utlity model has are:
The blade plate with the two thread lock pressurization of Eight characters hole of the present utility model, the structure of more fixed form for Various Complex fractures is provided, two ends female thread tapering is 20 °, and there is lock function at two ends, thereby it is tight to carry out any side chain according to clinical demand; Because two ends, hole have again pressurization and universal pressurization, the longitudinal maximum angle of its screw is 80 °, and laterally maximum angle is 10 °, can select any one end to pressurize, make screw need to adjust direction by clinical, reduced operation technique difficulty, improved operation quality and therapeutic effect.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the blade plate with the two thread lock pressurization of Eight characters hole of the present utility model is described further.Following each embodiment is only not limitation of the utility model for this utility model is described.
Fig. 1 is the structural representation of the blade plate with the two thread lock pressurization of Eight characters hole of the present utility model; Fig. 2 is the structural representation that the blade plate with the two thread lock pressurization of Eight characters hole of the present utility model is combined with screw; Fig. 3 is the structural representation of the screw hole of blade plate of the present utility model; Fig. 4 is that the longitudinal maximum angle of screw is the structural representation of 80 °; Fig. 5 is that the horizontal maximum angle of screw is the structural representation of 10 °.As shown in Figures 1 to 5, the blade plate with the two thread lock pressurization of Eight characters hole of the present utility model, comprises blade plate main body 1 and is arranged on the multiple screw holes 2 in blade plate main body 1.Screw hole 2 is the two thread lock pressurization of splayed hole, os integumentale screw that can outfit standard, cancellous bone screw and lock screw, the standard screws 4 and the lock screw 3 that are widely used in plate are combined with, more fixed form is provided, and is a structure for Various Complex fractures.
It is the female thread of 20 ° that the two ends of screw hole 2 are tapering, and two ends lock function can be provided, and is suitable for lock screw, and this structure is not compressed periosteum or destroyed fracture, hematoma, thus improve the chance of union of fracture; Be provided with and two add pcketing, two ends pressurization and universal pressurization can be provided, be suitable for os integumentale screw and cancellous bone screw.
The width of screw hole splayed junction is greater than the diameter that is connected to the screw in screw hole, and the longitudinal maximum angle of its screw is 80 °, and laterally maximum angle is 10 °, makes screw need to adjust direction by clinical, reduces operation easier, improves therapeutic effect.
The blade plate with the two thread lock pressurization of Eight characters hole of the present utility model can adopt medical stainless steel material, titanium alloy and pure titanium to process.Can be equipped with the bone screw of corresponding material.Eight characters two ends all have locking and pressurization function can use separately lock screw or forcing screw in any side in hole according to clinical demand, forcing screw can be adjusted angle according to clinical demand, thereby there is high degree of flexibility and better therapeutic effect, increase the reliability of fracture fixation, make bone fracture internal fixing device tool more solid and reliable, the accelerating bone healing time, thus guarantee successful surgery, reduce patient suffering.
