Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of near end of thighbone universal lock steel plate.
Background technology
Along with the arrival of aging society, fractured near end of thighbone sickness rate increases day by day.Especially intertrochanteric fracture of the femur, elderly patient, owing to often merging serious osteoporosis and more internal medicine illness, causes great trouble to the treatment of this type of fracture; And intertrochanteric fracture of the femur sorting technique is more, Accurate classification carries out to the intertrochanteric fracture of complexity more difficult.Current application is applied to the Therapeutic Method of fractured near end of thighbone, immobilization material is more, current near end of thighbone steel plate is all fixed angle, can not good selected angle in clinical course, more single, the fracture of femoral neck case for complexity well can not play the effect of the reduction of the fracture.Very easily occur interfering between primary election locking lock screw when the different skeleton of adaptation.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of near end of thighbone universal lock steel plate, engaged with lock screw by crosswise groove, turn locking screw adjustment screw tab axial location, is convenient to prevent lock screw from mutually interfering when the different bone of adaptation.
This utility model solves the technical scheme that its technical problem adopts: described a kind of near end of thighbone universal lock steel plate, this locking steel plate is an arc fixed plate, it body comprising head and be attached thereto, described head plate body is provided with three threaded locked holes, described three holes are in falling the distribution of " product " word, for being screwed into the locking screw of spongy bone, axis direction and the plate body structure of these three threaded locked holes have angle, multiple screw is had at described lockplate body, described head is provided with several guide pinholes, described threaded locked holes sidewall is cambered surface, the disc screw tab around own axis is provided with in described threaded locked holes, the sensing of described screw tab its axis when own axis changes, described screw tab end face offers the crosswise groove of intersection point at screw tab.
Engaged with lock screw by crosswise groove in above-mentioned design, turn locking screw adjustment screw tab axial location, is convenient to prevent lock screw from mutually interfering when the different bone of adaptation.
As the better improvement of the design, described threaded locked holes is ellipse perpendicular to the cross section of own axes, and namely described screw tab is inclined and mounted in threaded locked holes, and its axis is circular along with screw tab rotates inswept track.The cross section of threaded locked holes is that ellipse is convenient to its orientation of its axis change while screw tab rotates.
As the better improvement of the design, the described body back side is provided with towards the breach of sides of body.Described breach is convenient to curved body portion and body surface there will not be gauffer.
As the better improvement of the design, each described screw edge is also provided with the pressurization hole overlapping with described threaded bore portion.
The beneficial effects of the utility model are: this utility model is engaged with lock screw by crosswise groove, and turn locking screw adjustment screw tab axial location, is convenient to prevent lock screw from mutually interfering when the different bone of adaptation.

Detailed description of the invention
This utility model is described in detail, illustrative examples wherein and illustrate and be only used for explaining this utility model below in conjunction with accompanying drawing and specific embodiment, but not as to restriction of the present utility model.
As shown in the figure, described a kind of near end of thighbone universal lock steel plate, this locking steel plate is an arc fixed plate, it body 1 comprising head 4 and be attached thereto, described head 4 plate body is provided with three threaded locked holes 6, described three holes are in falling the distribution of " product " word, for being screwed into the locking screw of spongy bone, axis direction and the plate body structure of these three threaded locked holes 6 have angle, multiple screw 8 is had at described lockplate body 1, described head 4 is provided with several guide pinholes 2, described threaded locked holes 6 sidewall is cambered surface, the disc screw tab 3 around own axis is provided with in described threaded locked holes 6, the sensing of described screw tab 3 its axis when own axis changes, described screw tab 3 end face offers the crosswise groove 7 of intersection point at screw tab 3.
Engaged with lock screw by crosswise groove 7 in above-mentioned design, turn locking screw adjustment screw tab 3 axial location, is convenient to prevent lock screw from mutually interfering when the different bone of adaptation.
As the better improvement of the design, described threaded locked holes 6 is ellipse perpendicular to the cross section of own axes, and namely described screw tab 3 is inclined and mounted in threaded locked holes 6, and its axis is circular along with screw tab 3 rotates inswept track.The cross section of threaded locked holes 6 is that ellipse is convenient to its orientation of its axis change while screw tab 3 rotates.
As the better improvement of the design, described body 1 back side is provided with towards the breach 5 of body 1 side.Described breach 5 is convenient to curved body portion 1 and body 1 surface there will not be gauffer.
As the better improvement of the design, each described screw 8 edge is also provided with pressurization hole 9 partly overlapping with described screw 8.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize this utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
