The Therapeutic Method of fracture of femoral neck is divided into expectant treatment and operative treatment, for labile fracture of femoral neck, generally all adopt operative treatment, for younger patient, the general internal fixation treatment that adopts more, three pieces of hollow screw technique for fixing of the many employings of Fixation Treatment of Femoral Neck Fracture at present, inserting needle from femoral bone tuberosity, through femoral trochanteric, femoral neck is to femoral head, play fixing fracture site effect, the defect of this kind of technology is: because three pieces of hollow screws do not interrelate, there is no other supports and fixing yet, in the process of neck of femur healing, easily cause locking pin to exit, fixing stability is also poor in addition, easily produce in femoral head and receive and be shifted, cause receiving in hip joint lopsided.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of stability good near end of thighbone locking system.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of near end of thighbone locking system, comprise: lockplate and the lock screw matching with lockplate, described lockplate comprises: tuberosity supporting plate part and gripper shoe part, tuberosity supporting plate part is provided with a pilot hole and three the first fixing holes, described supporting board is arranged with second fixing hole, the setting triangular in shape of described three the first fixing holes, described lock screw comprises three the first lock screw and second lock screw, described three the first lock screw match with three the first fixing holes respectively, described the second lock screw matches with the second fixing hole.
As the preferred technical scheme of one, described the first fixing hole and the second fixing hole are screwed hole.
As the preferred technical scheme of one, one end that described the first lock screw matches with the first fixing hole is provided with the first thread segment, and the other end is provided with the second thread segment, and the pitch of described the second thread segment is greater than the pitch of the first thread segment.
As the preferred technical scheme of one, described lockplate and lock screw are made by titanium alloy material.
As the preferred technical scheme of one, between the plate face of described tuberosity supporting plate part and the plate face of gripper shoe part, be bending setting, the plate face of bending place is arc transiting surface.
The beneficial effects of the utility model are: this utility model is an entirety after lockplate and lock screw are tightened, and femoral head and neck is had to stable supporting role, is conducive to the healing of fracture and prevents the shortening of neck of femur and move back nail.

The specific embodiment
In order further to understand this utility model, below in conjunction with embodiment, this utility model preferred embodiment is described, but should be appreciated that these describe just as further illustrating feature and advantage of the present utility model, rather than restriction to this utility model claim.
Refer to Fig. 1 to Fig. 6, a kind of near end of thighbone locking system, comprise: lockplate 1 and the lock screw 2 matching with lockplate 1, described lockplate 1 comprises: tuberosity supporting plate part 3 and gripper shoe part 4, tuberosity supporting plate part 3 is provided with a pilot hole 30 and three the first fixing holes 31, described gripper shoe part 4 is provided with second fixing hole 40, the setting triangular in shape of described three the first fixing holes 31, described lock screw 2 comprises three the first lock screw 20 and second lock screw 21, described three the first lock screw 20 match with three the first fixing holes 31 respectively, described the second lock screw 21 matches with the second fixing hole 40.Described the first fixing hole 31 and the second fixing hole 40 are screwed hole.One end that described the first lock screw 20 matches with the first fixing hole 31 is provided with the first thread segment 201, and the other end is provided with the second thread segment 202, and the pitch of described the second thread segment 202 is greater than the pitch of the first thread segment 201.Described lockplate 1 and lock screw 2 are made by titanium alloy material.Between the plate face of described tuberosity supporting plate part 3 and the plate face of gripper shoe part 4, be bending setting, the plate face of bending place is arc transiting surface.In this utility model, the overall structure of lockplate is irregular curved-surface structure, and the benefit of design is to make lockplate better to fit in femoral bone tuberosity and femoral shaft like this, to improve postoperative stability.
