Abstract
An orthopaedic surgical instrument for use in resecting a patient's bone is disclosed. In some embodiments, the instrument may be for single patient use and may be disposed of at the end of each surgical procedure.
Claims15
An orthopaedic surgical instrument, comprising:
- an intramedullary rod configured to be inserted into a medullary canal of a patient's bone,
- a housing coupled to the intramedullary rod, the housing including a pair of arms spaced apart to define an elongated slot, each arm including a first longitudinal rib formed on a proximal surface and a second longitudinal rib formed on a distal surface positioned opposite the proximal surface,
- a translation frame configured to slide along the pair of arms, the translation frame comprising:
- a first body including a central section positioned in the elongated slot of the housing and a pair of first flanges extending outwardly from the central section, each first flange including a proximal surface that engages the first longitudinal rib of one of the pair of arms,
- a second body coupled to the first body, the second body including a pair of second flanges, and each second flange includes a distal surface that engages the second longitudinal rib of one of the pair of arms to couple the first body and the second body to the housing, the second body also includes a base plate and an elongated shaft that extends outwardly from the base plate through the central section of the first body,
- a fastener secured to the elongated shaft of the second body to couple the second body to the first body, and
- a mounting bracket coupled to the first body and the second body, and
- a cutting block coupled to the mounting bracket such that the cutting block is configured to slide with the translation frame, the cutting block including a cutting slot sized to receive a cutting tool to guide a resection of the patient's bone.
