The disclosure relates to methods of preparing a femur for hemi arthroplasty or total hip replacement. An aim is to create a channel through the femur, for receipt of a vent tube, which can be attached to a surgical suction device to lower the pressure on the mid and distal femur and thereby prevent or at least reduce a risk of embolisation. The channel may be created from (and accessed via) a proximal end of the femur or a distal end of the femur. Furthermore, the methods disclosed herein may be selectively used with cemented or uncemented components and with flat (blade-shaped) or rounded (conical) femoral stem components.

The invention provides a cold region orthopedics department digital intelligence diagnosis and treatment intelligent operation planning system comprising a total knee joint replacement planning module used for planning according to an acquired knee joint medical image and cold region specificity data; the total hip replacement planning module is used for planning according to the acquired hip joint medical image and cold region specificity data; the unicondylar joint replacement planning module is used for planning according to the obtained knee joint medical image and cold region specificity data; the acetabulum periphery osteotomy planning module is used for planning according to the obtained hip joint medical image and cold region specificity data; the sports medical planning module is used for planning according to the acquired joint medical image and cold region specificity data; the spine planning module is used for planning according to the spine medical image and the cold region specificity data; and the trauma planning module is used for performing trauma operation planning according to the trauma part medical image and the cold region specificity data.

The utility model relates to the field of positioning devices, in particular to a complete positioning device for artificial total hip replacement, which is characterized in that a leg support bracket is mounted at the upper part of a bottom plate through a rotating seat, a cover plate is mounted at the upper part of the leg support bracket in a covering manner, and a pair of double-end opposite lead screws is mounted in the middle of the cover plate; threaded sections with opposite rotating directions are arranged at the two ends of the double-end opposite lead screw respectively, sliding blocks are connected to the threaded sections at the two ends in a threaded mode respectively, positioning rods are installed at the bottoms of the sliding blocks, and when the double-end opposite lead screw rotates, the sliding blocks at the two ends are driven by spiral rotation to achieve opposite displacement. According to the utility model, the leg supporting bracket supports and positions the thighs of a patient, the leg supporting bracket realizes a rotary locking function through the components such as the rotary seat and the fastening bolt, the cover plate is matched with the solid rod to press the legs so as to finish a vertical positioning function, and meanwhile, the double-end opposite screw rod is rotated to drive the positioning rods to move in opposite directions, so that the leg supporting bracket can be used for supporting the thighs of the patient. Therefore, the legs are clamped and locked, the left-right positioning function is achieved, and the stable positioning effect is achieved.
