Implanting guiding device for three cannulated screws for femoral neck fracture surgery

Abstract

The invention discloses an implanting guiding device for three cannulated screws for femoral neck fracture surgery. The implanting guiding device comprises a guiding plate, the center of the guiding plate is provided with a center circular hole, the right side of the center circular hole is provided with a rhombic circular hole array, any side of the rhombic circular hole array is constituted by three circular holes, the center of the rhombic circular hole array is further provided with a center circular hole, a connecting line of the center circular hole of the rhombic circular hole array andthe center circular hole of the guiding plate is located on a transverse center line of the guiding plate, the upper left corner of the center circular hole of the guiding plate is provided with an inverted trapezoidal circular hole array, the lower left corner of the center circular hole of the guiding plate is provided with a trapezoidal circular hole array, the inverted trapezoidal circular hole array is constituted by four transversely-arrayed circular holes, three transversely-arrayed circular holes and two transversely-arrayed circular holes in an arrayed mode in sequence, the trapezoidal circular hole array is constituted by two transversely-arrayed circular holes, three transversely-arrayed circular holes and four transversely-arrayed circular holes in sequence, and one side edgeof the guiding plate is provided with scales. Through in-vitro precise positioning, the three cannulated screws in the femoral neck fracture surgery are quickly and accurately implanted.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to an implant guide, in particular to an implant guide device for three hollow nails used in femoral neck fracture surgery. Background technique [0002] Femoral neck fractures often occur in middle-aged and elderly people. With the development of society, femoral neck fractures in young and middle-aged people caused by traffic injuries, falls from heights and other reasons are increasing year by year. The nonunion rate and femoral head necrosis rate of femoral neck fracture are even as high as 60%, which is the main problem of clinical treatment. [0003] For young and middle-aged patients with femoral neck fractures younger than 60 years old or elderly patients with better bone quality, fixation with three cannulated screws is still the preferred treatment option at present. However, due to inaccurate intraoperative positioning, it is often necessary to repeatedly implant hollow na...
