Abstract: A surgical instrument includes a body member and a leg having a first end integrated with and extending from the body member. A head cavity is in the leg portion to hold a head. A channel is formed along a longitudinal length of the leg. An elongated rocker assembly includes an elongated lever arm coupled within the channel about a fulcrum and a spring actuation. A projection of the arm projects in a direction of the head cavity. A rocker slide lock has a collar slidably coupled around the body member and having a first position located between the body member and the actuation tab, such that a portion of the collar is under the actuation tab to limit pivotal motion of the rocker assembly, and a second position having a clearance from under the actuation tab.

Abstract: A modular surgical instrument is provided that includes a tower having a first end, a second end and a ratchet segment between the first end and the second end. The instrument includes a ratchet reduction mechanism. The ratchet reduction mechanism includes a ratchet lever, a linear ratchet rack integrated into a ratchet segment of the tower at a location between the first end and the second end, and a ratchet collar coupled to the ratchet lever. The ratchet collar is configured to slide along the ratchet segment by application of an applied force. The instrument includes a reducer that may be affixed to the ratchet reduction mechanism. The reducer is configured to move in unison with the slide of the ratchet collar.

Abstract: A system comprising surgical instruments of different types. Each surgical instrument includes a body member and a leg having a first end integrated with and a leg portion extending from the body member. The instrument includes a head cavity formed in a free end of the leg. The cavity holds a head. A channel is formed along a portion of a longitudinal length of the leg. The instrument includes an elongated rocker assembly pivotally coupled within the channel, with a spring actuation tab in proximity to the body member. The instrument includes a collar slidably coupled around the body member and having a first position located between the body member and the actuation tab such that a portion of the collar is under the actuation tab to limit pivotal motion of the rocker assembly and a second position of the collar has a clearance from under the actuation tab.

Abstract: A power tool includes a motor assembly, a base assembly, and a clamp assembly coupled to the motor assembly or the base assembly to selectively provide a retention force to the other to removably couple the motor assembly and the base assembly. The clamp assembly includes a handle member, a fulcrum member, and a biasing lever member. The lever member includes a first portion and a second portion disposed on opposite sides of the fulcrum member. The handle member is coupled to the first portion, and the handle member is movable between an open and closed position. The handle member rotates the first and second portions of the biasing lever member about the fulcrum member when moving from the open to the closed position, causing the second portion of the lever member to provide the retention force.
