Abstract
Provided is a shelf bracket type locking steel plate. The shelf bracket type locking steel plate belongs to the field of medical instruments. By means of the triangle-supporting form shelf bracket type locking steel plate composed of a steel plate and a fixing nail, the shelf bracket type locking plate aims to solve problems of an existing fracture fixation. The steel plate which matches with an outside of a thighbone and a shaft of thighbone comprises a main locking screw hole and a supporting lever hole. A thread matching with a tail end of a main locking screw is arranged in the main locking screw hole, and a thread matching with a tail end of a supporting lever is arranged in the supporting lever hole. In addition, the front end of the main locking screw is provided with a groove, and a front top of a supporting screw is abutted in the groove. The shelf bracket type locking plate is simple in structure and convenient to operate and use. By means of an installation of the shelf bracket type locking plate, a triangle-supporting state is achieved, reasonable supporting effect can be achieved in mechanics, each angle is stressed uniformly, and secondary fracture can be avoided.
Description
Technical field
This utility model belongs to field of medical.
Background technology
Owing to multiple reason, the phenomenon of possibly fracturing need carry out fixing through steel plate etc. at fracture site this moment, guarantees that the normal growth of skeleton recovers.Yet the existing fixed mode is when some angle is stressed; Cause the secondary fracture easily; Fracture of the femoral head for example causes fractured near end of thighbone, just intertrochanteric fracture of the femur or femoral subtrochanteric fracture etc. when in being easy under the existing fixed mode to receive, turning over power.
Summary of the invention
The purpose of this utility model is to solve the problem that existing fracture fixation mode exists, through steel plate, staple being formed the A-frame formula locking steel plate of gusseted form.
This utility model is to join on the steel plate of type with the femur femoral shaft outside to comprise main locking nail hole and support rod hole; Screw thread with main pinning tail end coupling is arranged in main locking nail hole; Screw thread with support bar tail end coupling is arranged in the support rod hole, at the front end of main pinning groove is arranged, the preceding top of a nail withstands in the groove.
This utility model master locking nail hole and femoral shaft vertical angle are 70 degree, and a nail hole and femoral shaft vertical angle are 40 degree.
The internal diameter of this utility model master locking nail hole is 10mm, and the external diameter of main pinning is 8.5mm; Support rod hole internal diameter 7mm, support bar external diameter are 5mm.
This utility model is simple in structure, and is easy for operation, and its installation becomes the gusseted state, on mechanics, can reach reasonable support effect, and all angles are evenly stressed, prevents that secondary fracture phenomenon from taking place.
Description of drawings
Fig. 1 is the structural representation of this utility model with the femoral head fixed form.
The specific embodiment
This utility model is to join on the steel plate 1 of type with the femur 5 femoral shaft outsides to comprise main locking nail hole 6 and support rod hole 7; Screw thread with main pinning 2 tail ends coupling is arranged in main locking nail hole 6; Screw thread with support bar 3 tail ends coupling is arranged in the support rod hole 7; Front end at main pinning 2 has groove 4, and the preceding top of a nail 3 withstands in the groove 4.
This utility model master locking nail hole 6 is 70 degree with the femoral shaft vertical angle, and a nail hole 7 is 40 degree with the femoral shaft vertical angle.
The internal diameter of this utility model master locking nail hole 6 is 10mm, and the external diameter of main pinning 2 is 8.5mm; Support rod hole 7 internal diameter 7mm, support bar 3 external diameters are 5mm.
With the femoral head fixed form is that example is described in detail:
At first main pinning being passed main locking nail hole imports into; Femoral shaft end and femoral head are fixed; And keep under groove 4 correspondences, will prop up nail then and pass a nail hole, till being to support in the groove 4 that the screw top end withstands on main pinning; Like this, main pinning, a nail and steel plate are formed a firm triangular support.
