Title:
INTERNAL PELVIC FIXATOR
Document Type and Number:
WIPO Patent Application WO/2016/209947
Kind Code:
A3
Abstract:
A system for internal pelvic fixation. Guide wires (108) can be inserted through guides (106) on opposing sides of a pelvic bone, and can indicate a depth for driving bone screws (122) into the pelvic bone. Offset rod tools positioned about each guide can assist in determining an offset distance between an implant rod and the pelvic bone. A template rod (126) may be coupled to the offset rod tools and used to select a length for the implant rod (140). Clamps (138) can be coupled to the bone screws, the clamps having multiple axes of rotation, the angular positions of the clamps being secured by the tightening of a single nut (146) of each clamp. Joysticks (166) used to tighten the nuts can be coupled to a reduction holder mechanism (200) that can decrease at least an axial distance between the clamps, and thus pelvic bones, before locking of the clamps via tightening of the nuts.
