Abstract
The utility model discloses an intertrochanteric fracture femoral handle. The femoral handle consists of a femoral neck, a cervical vertebra, a femoral section and a handle body; the top of the femoral section is provided with a bolt hole connected with a surgical tool; the near end of the femoral section is provided with one or more transverse through holes; and a neck support is arranged inside the lower edge of the femoral section. The femoral section can replace the defective femoral part to keep the length of a limb; the femoral section is provided with the holes, and a fractured big protrusion can be bound on the femoral section, so that original functions of a hip joint are kept by means of ligaments and soft tissues. Meanwhile, the neck support is arranged inside the lower edge of the femoral section, an implanted prosthesis is seated on a hard cortical bone layer nearby a small protrusion, so that supporting of the prosthesis is increased, sinking is prevented, and the aim of long-term stabilization is fulfilled.

Intertrochanteric fracture is seen the prominent grand splitting of size more, is broken, even pulverizes.At present, how the conventional femoral hip stem that first replacement operation uses or overhaul and use type femoral bone end prosthesis is not with femur fragment, suitablely treats this disease.
The utility model content
The purpose of this utility model is, to the problems referred to above, proposes a kind of band femur fragment intertrochanteric fracture femoral stem, and the femoral component of alternative damage keeps limbs length.
For realizing above-mentioned purpose; The technical scheme that this utility model adopts is: the intertrochanteric fracture femoral stem; It is made up of neck of femur, cervical vertebra, femur fragment and handle body; The top of femur fragment is provided with the bolt hole that is connected with operation tool, and the femur fragment near-end is provided with the through hole of one or more lateral direction penetratings, and inboard, femur fragment lower edge is provided with the neck holder.
Further, cervical vertebra is a truncated cone-shaped, and its gradient is 1:10, and the upper and lower opening diameter is respectively 12/14mm.
Further, femur fragment be the outside thick 15 to 25mm, inboard thick 10 to 25mm approximate trapezoid section, wide is 20 to 30mm.
Further, handle height 140 is to 280mm, 1 to 3 ° of tapering, and upper coarse and lower fine, distal diameter is that Φ 8 is to 14mm.
Further, intertrochanteric fracture femoral stem surface is dull surface or high burnishing surface.
Further, micropore surface is made for the rough surface of blasting treatment or through spraying, sintering and energetic ion smelting process in intertrochanteric fracture femoral stem surface.
Further, it is connected with the medullary cavity internal fixation through bone cement.
Further, it is connected with the medullary cavity internal fixation through medullary cavity self skeleton.
The beneficial effect of this utility model is following:
The intertrochanteric fracture femoral stem that this utility model provides, the band femur fragment, alternative damaged femoral component keeps limbs length, and is porose on it, can the original function of on femur fragment, borrowing its ligament and soft tissue to keep hip joint be pricked in the big prominent grand binding that fracture.Simultaneously, there is the neck holder the inboard lower edge of femur fragment, and after the implantation, prosthese is seated near the hard cortex osteoplaque little prominent the swelling, and increases the support of prosthese, helps stoping and sinks to reaching purpose steady in a long-term.
Through accompanying drawing and embodiment, the technical scheme of this utility model is done further detailed description below.
