Problems solved by technology

Such as: femoral neck fractures, forward and reverse intertrochanteric fractures, subtrochanteric fractures, etc., but its biggest advantage is the use of multi-segment femoral fractures, such as: femoral neck fractures combined with shaft fractures, for A2 and A3 fractures, intramedullary nails It is more firmly fixed than the bone plate. For femoral fractures, the intramedullary nail often penetrates the medial wall of the femur due to angle problems during nailing. After repeated adjustments through the C-arm fluoroscopy machine, there will be angle deviation during the operation, and it consumes time consuming

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing:

[0022] like Figure 1-Figure 8 As shown, the proximal femoral intramedullary nail guide includes a base 1, a support rod 3, a scale 5, a fixed vertical rod 8, a guide cylinder 11 and a cross rod 14, and the support rod 3 is fixed by the support rod fixing adjustment knob 2 On the base 1, a fixed vertical bar 8 is connected to the top of the support bar 3, and the fixed vertical bar 8 is provided with a sliding sleeve 20 and a sliding sleeve 2 23. The sliding sleeve 20 is welded with a dial A6, and the sliding sleeve 2 23 is provided with There is a scale plate B10, the sliding sleeve 2 23 is set under the sliding sleeve 1 20, and the side of the dial A6 marked with the scale is provided with a scale 15, the scale 1 5 passes through the rotating shaft 21 and is fixed by the scale 1 adjusting knob 4, and the rotating shaft is fixed The knob 18 passes through the sliding slee...

Abstract

The invention discloses a guiding device for placement of proximal femoral nails. The guiding device includes a base, a supporting rod, a first ruler, a fixing vertical rod, a guiding sleeve and a cross bar. The supporting rod is fixed to the base through a supporting rod fixing adjustment rotary knob, the fixing vertical rod is connected to the upper portion of the supporting rod, a first slidingsleeve and a second sliding sleeve are arranged on the fixing vertical rod, a dial A is welded to the first sliding sleeve, and a dial B is welded to the second sliding sleeve; the second sliding sleeve is arranged below the first sliding sleeve, the first ruler arranged on the graduated surface of the dial A penetrates through a rotating shaft and is fixed by a first ruler adjusting rotary knob,a rotating shaft fixing rotary knob penetrates through the second sliding sleeve to fix the rotating shaft, and a retractable contrast ruler is perpendicularly connected to one side of the first ruler. The guiding device has the advantages of being simple in structure, low in cost, easy to operate and capable of preventing a nail embedding device from penetrating through the lateral side of the femur during dismounting surgery so that surgical risks can be reduced.

Description

technical field [0001] The invention relates to the field of orthopedic medical instruments, in particular to a guider for placing intramedullary nails in the proximal femur. Background technique [0002] Intramedullary femoral nails have a wide range of indications and can be used for almost all femoral fractures. Such as: femoral neck fractures, forward and reverse intertrochanteric fractures, subtrochanteric fractures, etc., but its biggest advantage is the use of multi-segment femoral fractures, such as: femoral neck fractures combined with shaft fractures, for A2 and A3 fractures, intramedullary nails It is more firmly fixed than the bone plate. For femoral fractures, the intramedullary nail often penetrates the medial wall of the femur due to angle and other problems during nailing. After repeated adjustments through the C-arm fluoroscopy machine, there will be angle deviation during the operation, and it consumes a lot of time. Time consuming. Therefore, a precise p...
