US 12,433,654 B2 · Lisfranc reconstruction device, kit, and method

Abstract

A Lisfranc reconstruction device includes a pair of operator grips mechanically linked to a first arm that includes a barrel and a second arm that includes a jaw whereby motion of the grips is mechanically transformed into relative translation of the barrel and the jaw for compression of a portion of a Lisfranc joint complex therebetween. The device includes a retention mechanism, such as a ratchet, to enable retention of the barrel and jaw when the desired position has been reached. The device may be provided in the form of a kit that includes a wire guide sleeve, a pilot wire, and a Lisfranc screw, in particular a cannulated Lisfranc screw that is sized to travel over the wire in a defined trajectory to facilitate proper screw placement. The device may be used for reconstruction of a traumatic injury to the Lisfranc joint complex.

Dependent claims

A Lisfranc reconstruction device comprising:

first and second operator grips, said first operator grip connected to a first link and said second operator grip connected to a second link, said first and second operator grips being movable relative to one another upon manual compression;
a mechanical linkage coupling said first link and said second link to a first arm that includes a barrel and a second arm that includes a jaw, the mechanical linkage including at least a prismatic joint, the mechanical linkage converting motion of the first and second operator grips into relative translation of the barrel and jaw;
a retention mechanism for retaining a relative position of the barrel and jaw relative to one another.
