Claim:
1. An orthopaedic surgical instrument, comprising: a handle including (i) an elongated body extending from a distal end to a proximal end, the elongated body having (a) a first side wall having a first elongated opening defined therein, (b) a second side wall having a second elongated opening defined therein, (c) a cavity defined therein, and (ii) a guide pin extending from the proximal end, a first lever extending outwardly from the cavity to a distal end through the first opening, the first lever including a proximal end that is pivotally coupled to the elongated body within the cavity, a second lever including (i) a lever body extending outwardly from the cavity to a proximal end through the second opening, the lever body having a distal end that is pivotally coupled to the elongated body within the cavity, and (ii) a catch extending from the proximal end of the lever body, and a leaf spring connecting the first lever to the second lever such that movement of the first lever causes movement of the second lever, wherein the first lever is pivotal between (i) an unclamped position in which the distal end of the first lever is spaced a first distance from the elongated body and (ii) a clamped position in which distal end of the first lever is spaced a second distance from the elongated body that is less than the first distance, wherein (i) when the first lever is in the unclamped position, the second lever is in a first position in which the catch is spaced a first distance from the guide pin and (ii) when the first lever is in the clamped position, the second lever is in a second position in which the catch is spaced a second distance from the guide pin that is less than the first distance, wherein the leaf spring is placed in tension when the first lever is in the clamped position to lock the second lever in the second position, and wherein the cavity includes an interior wall facing the second opening wherein the interior wall and the second side wall define an oblique angle, the lever body of the second lever includes an arm coupled to the catch and a shoulder coupled between the arm and the distal end, wherein an angled surface of the shoulder faces the interior wall, and the angled surface of the shoulder defines an oblique angle with respect to an interior surface of the arm, and the angled surface of the second lever engages the interior wall when the second lever is in the second position.
