Problems solved by technology

The proximal femoral intramedullary nail belongs to the intramedullary fixation, the torque is short, and it can bear early load. However, because the proximal end of the intramedullary nail is too thick, it will cause great damage to the bone of the femoral trochanter. When the main nail is nailed, the fracture displacement will be aggravated, resulting in increased postoperative internal bleeding

Embodiment Construction

[0016] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0017] see figure 1 , the embodiment of the present invention includes:

[0018] An osteosynthesis device for treating intertrochanteric fractures of the femur, comprising: a bone plate 1, a helical knife 2, and a fixation screw 3; the bone plate 1 includes the upper part 6 of the bone plate, the middle part 7 of the bone plate, and the bone plate connected in sequence The lower part 8; the upper part 6 of the bone plate corresponds to the greater trochanter 10 of the femur 9 in an arc shape, the middle part 7 of the bone plate is obliquely arranged at the lower end of the upper part 6 of the bone plate, and the middle part 7 of the bone plate is...

Abstract

The invention discloses a bone connecting device for treating femoral intertrochanteric fracture. The bone connecting device for treating femoral intertrochanteric fracture comprises a bone connecting plate, a circular knife and fixing screws, wherein the bone connecting plate comprises a bone connecting plate upper portion, a bone connecting plate middle portion and a bone connecting plate lower portion which are sequentially connected to one another; the bone connecting plate upper portion is arc-shaped; the bone connecting plate middle portion is obliquely arranged at the lower end of the bone connecting plate upper portion; the outer side of the bone connecting plate middle portion and the outer side of the bone connecting plate lower portion are straight; the bone connecting plate middle portion is thicker than the bone connecting plate upper portion and the bone connecting plate lower portion; a sleeve is arranged on the bone connecting plate middle portion; threads are arranged at the front end of the circular knife; and the rear of the circular knife does not have threads. When the bone connecting device is used, the circular knife is obliquely placed in a femoral head via a femoral neck from a greater trochanter, the threads of the circular knife are fixed in the femoral head, and the rear of the circular knife is slidably connected with the femoral neck and the sleeve; and the bone connecting plate upper portion and the bone connecting plate lower portion are provided with locking screw holes which are locked with the fixing screws in a threaded manner. By the mode, a fracture portion can be compressed, and a fracture line is reduced; and angular stability is high, displacement fracture can be prevented, injury is reduced, and healing on femoral intertrochanteric fracture is facilitated.

Description

Technical field [0001] The invention involves a improvement of a bone device that treats the fractures of the femoral bone rough. Especially a kind of pressing the fracture line to the fracture in the healing process, it has good angle stability, which can prevent fracture shift.Reduce the bone device that will be reduced to the femoral coarse damage and promote fracture healing. Background technique [0002] Bone thick bone fracture is a more common clinical fracture. Generally, the treatment method is to closely reset and slide the hip screw internal fixation (DHS), the internal fixation of the locking nail system, and the proximal femoral intraction (PFNA). Due to various internal internal internalThe fixed design is different, the characteristics of mechanics are different, and the efficacy and corresponding complications are different. [0003] Sliding hip screws in the hip screw (DHS), consisting of a bone panel with a sliding sleeve and a hollow tensile screw and number of...
