摘要： 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.

摘要： 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.

摘要： 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.
