Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
Please joining shown in Fig. 1 to Fig. 6, the orthopedic positioning guide plate of this utility model personalization near end of thighbone 100 is one-body molded by rapid shaping technique.The described personalized orthopedic positioning guide plate of near end of thighbone 100 is mounted on femur 500 near-end and can coordinate with nail (not shown) for fixing to carry out osteotomy, orthotic procedure or to install tradition blade plate in the punching of femur 500 relevant position. The described personalized orthopedic positioning guide plate of near end of thighbone 100 includes substantially base portion 1 in strip, by the extended straight up abutting part 2 in base portion 1 top and by the outwardly extended reinforcement 3 in the side of abutting part 2.
Described base portion 1 includes the main body 10 substantially arranged and the projection 16 being protruded out setting by main body 10 both sides along main body 10 thickness direction in tabular. The bottom thickness of described main body 10 is consistent, and the top of described main body 10 is that thickness is gradually increased trend setting. Described main body 10 front surface 11 includes plane 111 and the inclined plane 112 being connected with plane 111. Described base portion 1 has multiple interruption-like the first through hole 13 running through setting. Described main body 10 also has multiple interruption-like groove 14 running through setting. Described first through hole 13 connects with groove 14, is conducive to the blanking in guide plate 100 course of processing, it is to avoid the generation in solid hole, reduces consumptive material simultaneously. Described first through hole 13 is arranged along the rear surface 12 of front surface 11 and main body 10 that the thickness direction of main body 10 runs through main body 10. Described groove 14 is arranged along the right flank 18 of left surface 17 and main body 10 that the width of main body 10 runs through main body 10. Enclose between described projection 16 and main body 10 to set and be formed with accommodation space 161, be used for holding the organizational structuries such as corresponding ligament, to prevent main body 10 from extruding the organizational structuries such as the ligament on femur 500 when entirely conforming on femur 500, reduce the wound to patient. Described projection 16 has and the binding face 162 of surface, femur 500 relevant position laminating. The rear surface 12 of described main body 10 has interval when guide plate 100 is mounted on femur 500 and between the surface of femur 500 corresponding site.
Described base portion 1 also has and the friction part 15 of the described alternate setting of groove 14. Described friction part 15 is respectively arranged on the opposite sides of the main body 10 of base portion 1, for the holding guide plate 100 convenient for doctor. Described friction part 15 is located on left surface 17 and the right flank 18 of main body 10.
