Abstract
Abstract A medical instrument includes an elongated shaft, a plurality of implements mounted to the shaft, and an actuator coupled to produce relative movement between the implements. At least one of the implements is detachable from the shaft and the actuator and from another one of the implements. The actuator includes a distal portion with an inclined slot. One of the implements is detachably coupled to the slot such that movement of the actuator causes the relative movement between the implements. A coupler including an opening for receiving the actuator is mounted to a handle for rotation relative to the handle.
