US 12,599,389 B2 · Multi-sided cutting instrument for mobilizing small bones in the foot

Abstract

An orthopedic cutting instrument can be used to cut and release soft tissue to mobilize a bone for subsequent realignment of the bone. In some examples, the cutting instrument is configured with a handle and a cutting head. The cutting head has multiple cutting surfaces, such as a lead cutting surface and side cutting surfaces extending angularly away from the lead cutting surface. A mirror set of cutting surfaces may be provided on the opposite side of the cutting head. The cutting surfaces may be arranged to allow controlling cutting of soft tissue while limiting inadvertent deep penetration of the cutting instrument. In addition, the cutting surfaces may be arranged to allow back-and-forth cutting movement of the cutting head, which can be useful when working in a tight joint space.

Dependent claims

An orthopedic cutting instrument comprising:

(a) a handle having a length extending from a first end to a second end;
and
(b) a cutting head extending from the second end of the handle, the cutting head comprising:
(i) a leading cutting surface;
(ii) a first side cutting surface extending angularly outwardly from the leading cutting surface on a first side of the cutting head;
and
(iii) a second side cutting surface extending angularly outwardly from the leading cutting surface in a direction opposite the first side cutting surface on a second side of the cutting head,
wherein the leading cutting surface defines a trapezoid having a long base, a short base, a first leg joining the long base to the short base, and a second leg joining the long base to the short base, the long base of the trapezoid defining a distal-most end of the cutting head.
