Abstract
An orthopaedic surgical instrument system for use in preparing a patient's bone is disclosed. The surgical instrument includes a cutting guide block configured to be secured to a surgically-prepared surface of the patient's bone, and a cutting tool to be used in conjunction with the cutting guide block to resect a section of the patient's bone. A method of performing an orthopaedic surgery is also disclosed.
Claims26
An orthopaedic surgical instrument system comprising:
- a cutting tool including (i) a shank, (ii) a shaft extending distally from the shank, the shaft having a plurality of cutting flutes defined at its distal end, and (iii) an outer sleeve coupled to the shaft, and
- a cutting guide block, comprising:
- a superior surface,
- an inferior surface positioned opposite the superior surface, the inferior surface defining an imaginary plane, and
- a slot extending through the superior surface and the inferior surface, the slot defining a cutting guide that extends from a first end to a second end that is sized to receive the cutting tool,
- wherein when the slot is viewed in a cross-sectional plane extending perpendicular to the imaginary plane at each of a plurality of points between the first end and the second end, (i) the slot has a central axis that extends through the superior surface and the inferior surface, and (ii) an angle is defined between the central axis and the imaginary plane, the magnitude of the angle being non-constant between the first end of the cutting guide and the second end of the cutting guide.
An orthopaedic surgical instrument system comprising:
- a cutting tool including (i) a shank, (ii) a shaft extending distally from the shank, the shaft having a plurality of cutting flutes defined at its distal end, and (iii) an outer sleeve pivotally coupled to the shaft such that the shaft and the shank are permitted to rotate relative to the outer sleeve, and
- a cutting guide block including a slot that defines a cutting guide sized to receive the cutting tool.
A method of performing an orthopaedic surgery, the method comprising:
- positioning a cutting guide block on an end of a patient's bone,
- inserting a cutting tool into a slot defined in the cutting guide block such that a cutting angle is defined between the cutting tool and the patient's bone, and
- advancing the cutting tool along the slot to resect a portion of the patient's bone, wherein the shape of the slot causes the cutting angle to change as the cutting tool is advanced along the slot.
