ORTHOPAEDIC SURGICAL CUTTING BLOCK AND SAW CAPTURE APPARATUS

摘要

This invention is a surgical instrument (10) for shaping a patient's bone tissue at the joint to receive implant including a cutting block body (11) that is sized and shaped to fit a patient's long bone at the joint during joint replacement surgery. The block (11) is attachable to the patient's bone tissue at the joint area. A flat cutting guide surface (34) on the block body is provided for guiding a surgeon's saw blade (39) when the surgeon cuts bone tissue at the joint. A saw capture (12) removably attaches to the block body (11) at or near the flat cutting guide surface (34). The saw capture (12) also provides a flat cutting guide surface (20) thereon that is positioned generally parallel to the cutting guide surface (34) on the block body (11) during use, and a gap (40) being formed therebetween. Wedge locking connections (22, 23) are provided for affixing the saw capture (12) to the block body (11) at the flat cutting guide surface (34).
