Abstract
The utility model relates to a medical appliance for surgical operation, in particular to a femoral neck screw used for treatment of proximal femoral fractures, consisting of a screw head, a screw body and a screw tail which are integrated. The screw body is provided with thread which is trapezoidal, and the included angle between a side edge in a direction of the trapezoidal screw tail and a trapezoidal bottom edge ranges from 65 degrees to 75 degrees, and the included angle between a side edge in a direction of the trapezoidal screw head and the trapezoidal bottom edge ranges from 75 degrees to 85 degrees. The femoral neck screw is simple in structure, easy in processing, not easy to be loosened due to gripping force to bones and easy to be drawn off by aid of the thread, and reduces complications of surgery.
Description
Technical field
This utility model relates to a kind of surgical medical equipment, relates in particular to a kind of femur neck screw that is used for the treatment of fractured near end of thighbone.
Background technology
Human femur under loading fracture, the general now therapeutic modality that adopts be with screw and blade plate with the skeletal fixation that fractures, wait union of fracture, again screw is taken out.Screw is generally by the nail tail of drill bit shape, and the ailhead one of screwed nail body and band cross recess or hex slot constitutes.The screw thread of screw in the market is divided into two kinds, and a kind of is that the cross section is the screw thread of isosceles trapezoid, and a kind of is that the cross section is parabolic screw thread.These two kinds of screw threads respectively have weak point, and the screw thread in isosceles trapezoid cross section gets loose easily to the gmatjpdumamics deficiency of skeleton, and the screw thread in parabola cross section is at first processed difficulty relatively, and hammer into all inconveniences of choosing also.How to make a kind of simple in structurely, be difficult for getting loose, the screw that is easy to choose, inventor's problem that will solve just.
Summary of the invention
This utility model provides a kind of screw that is difficult for getting loose and is easy to choose.
Its concrete technical scheme is: a kind of femur neck screw that is used for the treatment of fractured near end of thighbone, ailhead, nail body, nail tail by integrated constitute, described nail is provided with screw thread on one's body, described thread segment is trapezoidal, and the angle that side on the described trapezoidal nail tail direction and trapezoidal base constitute is that 65 degree are to 75 degree angles; The angle that side on the described trapezoidal ailhead direction and trapezoidal base constitute is that 75 degree are to 85 degree angles.The cross section for tilt trapezoid screw thread since the angle of nail tail direction less than the angle of ailhead direction, hammer into and choose easilier.
As preferably, the angle that side on the described trapezoidal nail tail direction and trapezoidal base constitute is 65 degree angles; The angle that side on the described trapezoidal ailhead direction and trapezoidal base constitute is 80 degree angles.
As preferably, the described depth of thread is described trapezoidal height and the ratio of pitch is 5: 12.Wideer pitch makes gmatjpdumamics stronger.The ratio of the general depth of thread of the femur neck screw of selling on the market and pitch is 1.: 1.
This utility model is simple in structure, be easy to processing, the skeleton gmatjpdumamics is difficult for by force getting loose, because the structure of screw thread is easy to choose, reduced the generation of postoperative complication.
Description of drawings
Fig. 1 is this utility model structural representation;
Fig. 2 is this utility model thread segment structural representation.
The specific embodiment
Below in conjunction with Fig. 1, Fig. 2 this utility model embodiment 1 is described in further detail:
A kind of femur neck screw that is used for the treatment of fractured near end of thighbone, ailhead 3, nail body 2, nail tail 1 by integrated constitute, described nail body 2 is provided with screw thread 4, and described screw thread 4 cross sections are trapezoidal, and the angle that side on described trapezoidal nail tail 1 direction and trapezoidal base constitute is 65 degree angles; The angle that side on described trapezoidal ailhead 3 directions and trapezoidal base constitute is 80 degree angles.The described depth of thread is that described trapezoidal height is 0.5 millimeter, and described pitch is that each screw thread summit is 1.2 millimeters to the distance between the next screw thread summit.
Claims (3)
1. femur neck screw that is used for the treatment of fractured near end of thighbone, ailhead (3), nail body (2), nail tail (1) by integrated constitute, described nail body (2) is provided with screw thread (4), it is characterized in that, described screw thread (4) cross section is trapezoidal, and the angle that side on described trapezoidal nail tail (1) direction and trapezoidal base constitute is that 65 degree are to 75 degree angles; The angle that side on described trapezoidal ailhead (3) direction and trapezoidal base constitute is that 75 degree are to 85 degree angles.
2. a kind of femur neck screw that is used for the treatment of fractured near end of thighbone according to claim 1 is characterized in that, the angle that side on described trapezoidal nail tail (1) direction and trapezoidal base constitute is 65 degree angles; The angle that side on described trapezoidal ailhead (3) direction and trapezoidal base constitute is 80 degree angles.
3. a kind of femur neck screw that is used for the treatment of fractured near end of thighbone according to claim 1 is characterized in that, described trapezoidal height is 5: 12 with the ratio of pitch.
