Abstract
Disclosed is a femur stem compression locking blade plate which comprises a neck part, a body part and a rear part; compression holes are arranged on the body and the rear parts; the angle formed between the neck part and the body part is 160 degrees to 165 degrees corresponding to the near end anatomical surface of the femur; two screw holes with thread inside are arranged on the neck part and are conical; and the utility model has the advantages that in the utility model, the neck part is corresponding to the near end anatomical surface of the femur, the neck part is joint with the near end of the femur when the utility model is used; two screw holes with thread inside are arranged on the neck part and are conical; based on the design, a locking pin is in threaded connection with the utility model so that the compression effect inside the human body is realized, so the femur stem compression locking blade plate having a simple structure is a femur stem compression locking blade plate which can apply compression inside the human body and have the properties of rotation resistance and looseness-proof.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of neck of femur pressurizing locking blade plate.
Background technology
At present, Orthopeadic Surgery is done the bone fracture device that uses when the neck of femur cadre fractures internal fixation and is mainly comprised dynamic hip screw and lockplate clinically, and the dynamic hip screw blade plate partly is cervical region, body, afterbody; Design has the sleeve that stretches to femoral neck on the cervical region, cooperates the nail that slides to carry out fracture fixation, and the shortcoming of this blade plate is: complex structure, and operation easier is big, long incision, tissue is peeled off many, and wound is big, and the bone road is thick, anti-rotation performance is poor, and pressurization is limited, and anti-rotation performance is poor; Tail is followed closely easy slippage.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, can pressurize, resist the anti-slip neck of femur pressurizing locking blade plate of rotation in human body.
For achieving the above object, the technical scheme that this utility model adopted is:
A kind of neck of femur pressurizing locking blade plate comprises: cervical region, body and afterbody, body and afterbody are provided with the pressurization hole; It is characterized in that: cervical region becomes 160～165 ° of angles with body, corresponding with the near end of thighbone dissection surface; Cervical region has two screws, and screw is tapered, is provided with screw thread in the screw.
According to described neck of femur pressurizing locking blade plate, it is characterized in that: the axis of above-mentioned screw and blade plate body form angle, and for dissecting collodiaphyseal angle, the angle of dissecting collodiaphyseal angle is 90 °～135 °.
According to described neck of femur pressurizing locking blade plate, it is characterized in that: the planar vertical line of the axis of above-mentioned screw and blade plate cervical region constitutes angle, and for dissecting top rake, dissecting top rake is 10 °～30 °.
According to described neck of femur pressurizing locking blade plate, it is characterized in that: be parallel to each other between the axis of above-mentioned screw.
According to described neck of femur pressurizing locking blade plate, it is characterized in that: become cohesion angle or angle of splay, 5 °～15 ° of angles between the axis of described screw.
According to described neck of femur pressurizing locking blade plate, it is characterized in that: be provided with screw thread in the pressurization hole of described afterbody.
According to described neck of femur pressurizing locking blade plate, it is characterized in that: described afterbody is a semi-conical.
The utility model has the advantages that: because the cervical region in this utility model is corresponding with the near end of thighbone dissection surface, when using this utility model cervical region and near end of thighbone are fitted, and cervical region has two screws, screw is slightly tapered, be provided with screw thread in the screw, this design can make hollow locking and pressurizing peg be threaded with this utility model, in human body, produce pressurization function, so this utility model is a kind of simple in structure, the neck of femur pressurizing locking blade plate that the anti-rotation that can pressurize in human body is anti-slip.
Description of drawings
Fig. 1 is this utility model structural representation;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment this utility model is further described:
A kind of neck of femur pressurizing locking blade plate, as shown in Figure 1, 2, comprising: cervical region 5, body 2 and afterbody 1, body and afterbody are respectively equipped with pressurization hole 7; Cervical region becomes 160～165 ° of angles with body, corresponding with the near end of thighbone dissection surface; Cervical region has two screws 6, and screw 6 is tapered, is provided with screw thread in the screw, makes things convenient for pinning to lock.In the present embodiment, two screw centre distances are 12.5 millimeters, and the axis of screw and blade plate body form angle, for dissecting collodiaphyseal angle 3, are provided with 90 °, 100 °, 110 °, 120 °, 130 °, 135 ° multiple models.In the present embodiment, the planar vertical line of the axis of screw and blade plate cervical region constitutes angle, is to dissect top rake 9, and about branch two kinds, angle has 10 °, 15 °, 20 °, 25 °, 30 ° multiple models.In the present embodiment, can be parallel to each other between the axis of screw, perhaps become cohesion angle 4 or angle of splay, 5 °-15 ° of angles between the axis of screw.In the present embodiment, can be provided with screw thread 8 in the pressurization hole of afterbody, afterbody is a semi-conical, is convenient to Wicresoft's operation.
