Device for repositioning bone fracture fragments

A device for repositioning bone fracture fragments, comprising:

• a carrier assembly fastenable to an operating table and including a rail member;
• a first arm assembly attached to the carrier assembly, the first arm assembly configured to hold a first bone fracture fragment;
• a second arm assembly attached to the carrier assembly, the second arm assembly comprising:
• a first articulated joint, a second articulated joint, a third articulated joint, a first connection plate, and a second connection plate;
• the first articulated joint is attached to the carrier assembly;
• the first connection plate is disposed between the first articulated joint and the second articulated joint;
• the second connection plate is disposed between the second articulated joint and the third articulated joint;
• and a holder assembly disposed on the third articulated joint is configured to hold a second bone fracture fragment;
• an actuator assembly configured to adjust the second arm assembly;
• and
• an operating assembly configured to control an adjustment of the second arm assembly via the actuator assembly, the operating assembly disposed on the second arm assembly in a region of the third articulated joint such that the operating assembly is configured to undergo no movement with respect to the holder assembly of the second arm assembly when the second arm assembly is adjusted via the actuator assembly, and such that the operating assembly and the holder assembly move together with respect to the first arm assembly, and also with respect to the operating table when present, when the operating assembly activates the actuator assembly.

An operating table, comprising:

• a table portion having a leg supporting surface, the leg supporting surface being for supporting a patient's leg when present;
• and
• a device for repositioning bone fracture fragments, including:
• a carrier assembly including a fastening assembly configured to fasten the device to the table portion;
• a first arm assembly attached to the carrier assembly, the first arm assembly configured to hold a first bone fracture fragment;
• a second arm assembly comprising a first end attached to the carrier assembly and a second end extending laterally over the leg supporting portion, the second end having a holder assembly that is configured to hold a second bone fracture fragment;
• an actuator assembly configured to adjust the second arm assembly;
• and
• a manually operable operating assembly located on the second end of the second arm assembly and configured to control an adjustment of the second arm assembly via the actuator assembly such that the operating assembly undergoes no movement with respect to the holder assembly of the second arm assembly when the second arm assembly is adjusted via the actuator assembly;
• and
• wherein the second arm assembly, the holder assembly, and the operating assembly undergo movement via the actuator assembly with respect to the first arm assembly, and with respect to the leg supporting surface, upon operation of the operating assembly.

A device for repositioning bone fracture fragments, comprising:

• a first arm assembly comprising a first end and a second end, the first arm assembly configured to hold a first bone fracture fragment at the second end of the first arm assembly via a first bone fragment holding assembly;
• a second arm assembly comprising a first end and a second end, the second arm assembly spaced apart from the first arm assembly and configured to hold a second bone fracture fragment at the second end of the second arm assembly via a second bone fragment holding assembly;
• an operating assembly operatively connected to an actuator assembly to control one or more motors which in turn adjust the position and/or orientation of the second end of the second arm assembly with respect to a the second end of the first arm assembly via user hand contact applied to the operating assembly;
• wherein the operating assembly is disposed at a distal region of the second arm assembly such that the operating assembly undergoes no movement with respect to the second bone fragment holding assembly of the second arm assembly when the second arm assembly is adjusted via the actuator assembly.
