To achieve these goals, the technical solution of the utility model is:
A thigh-bone small tuberosity resetting fixer for tape guide device, comprises and holds hamulus of hamate bone, controls hamulus of hamate bone, guider, pressure rod and base bar outward; Describedly hold hamulus of hamate bone and base bar is one-body molded; Describedly outer control hamulus of hamate bone and pressure rod is one-body molded; Described pressure rod can slidably reciprocate on described base bar; Described guider is arranged on described pressure rod, with described pressure rod motion; Described guider is provided with the first through hole; Outside described, control hamulus of hamate bone and be provided with the second through hole; Described the first through hole and the second through hole are point-blank.
Further, described pressure rod is provided with screw rod, pressure rod motion described in described screw drive.
Further, described base bar is provided with the first chute and the second chute.
Further, described pressure rod one end is arranged on described the first chute slides within by locking nut; The other end of described pressure rod is arranged on described the second chute slides within by screw.
Further, described screw is also fixedly connected with described screw rod and pressure rod.
This utility model is owing to having adopted above-mentioned technology, and the good effect that makes it compared with prior art to have is:
This utility model is held hamulus of hamate bone and hamulus of hamate bone is controlled in outside owing to being provided with, and that holds that hamulus of hamate bone can be strong grasps the little tuberosity sclerite of free femur, and controls hamulus of hamate bone with outside and form three-jaw and grip; This utility model is owing to being provided with screw drive pressure rod, reseting fracture that can be reliable and stable; This utility model is owing to being provided with wire installation, and the second through hole that the guide pin that utilizes apparatus lower end is controlled hamulus of hamate bone through the first through hole on guider and outside, can squeeze into fixation guide pin accurately.
