Detachable End Effector with Lateral Lock

A surgical device comprises an elongate shaft comprising a distal end and a proximal end. An actuator is operably connected to the proximal end of the elongate shaft. The actuator may be a manual handle. An end effector is adapted for in vivo attachment to and detachment from the distal end of the elongate shaft. A loader is sized to receive the end effector. A lock extends laterally from the end effector and is operative to prevent the end effector from leaving the loader. The lock may move medially relative the end effector to allow the end effector to leave the loader.

Multifunctional Surgical Instrument With Flexible End Effector Tools

A surgical tool having proximal and distal ends and adapted to transverse a curved passageway comprises an end effector disposed on the distal end of the surgical tool, the end effector having a first body section and a second body section and a releasable connector joining the end effector first body section with the end effector second body section. The connector is operable to reversibly engage the first and second end effector body sections in a first fixed position and in a second movable position. The surgical tool further comprises an actuation device for moving the first and second end effector body sections from the first fixed position to the second movable position.
