A system comprising: a. a grasper (118, 218) comprising: i. a grasper housing having a distal end and a proximal end, the grasper housing defining a docking opening at the distal end, the docking opening having a shape, and ii. a jaw at the distal end of the grasper housing, the jaw including a first jaw portion and a second jaw portion, wherein at least one of the first and second jaw portions is movable relative to the other; b. a tool comprising: i. a tool housing having a distal end and a proximal end and defining an inner surface, ii. a docking assembly defined by the tool housing at the proximal end of the tool housing, the docking assembly comprising a first protrusion extending proximally from the proximal end of the tool housing and having a first protrusion shape complementary to the shape of the docking opening, and iii. an operative assembly at the distal end of the tool housing, the operative assembly comprising an instrument operably connected to the tool housing; and c. a robotic device operably coupled to the proximal end of the grasper (118, 218) and configured to actuate the first and second jaw portions of the grasper (118, 218) between a first position and a second position. a. a grasper (118, 218) comprising: i. a grasper housing having a distal end and a proximal end, the grasper housing defining a docking opening at the distal end, the docking opening having a shape, and ii. a jaw at the distal end of the grasper housing, the jaw including a first jaw portion and a second jaw portion, wherein at least one of the first and second jaw portions is movable relative to the other; i. a grasper housing having a distal end and a proximal end, the grasper housing defining a docking opening at the distal end, the docking opening having a shape, and ii. a jaw at the distal end of the grasper housing, the jaw including a first jaw portion and a second jaw portion, wherein at least one of the first and second jaw portions is movable relative to the other; b. a tool comprising: i. a tool housing having a distal end and a proximal end and defining an inner surface, ii. a docking assembly defined by the tool housing at the proximal end of the tool housing, the docking assembly comprising a first protrusion extending proximally from the proximal end of the tool housing and having a first protrusion shape complementary to the shape of the docking opening, and iii. an operative assembly at the distal end of the tool housing, the operative assembly comprising an instrument operably connected to the tool housing; and i. a tool housing having a distal end and a proximal end and defining an inner surface, ii. a docking assembly defined by the tool housing at the proximal end of the tool housing, the docking assembly comprising a first protrusion extending proximally from the proximal end of the tool housing and having a first protrusion shape complementary to the shape of the docking opening, and iii. an operative assembly at the distal end of the tool housing, the operative assembly comprising an instrument operably connected to the tool housing; and c. a robotic device operably coupled to the proximal end of the grasper (118, 218) and configured to actuate the first and second jaw portions of the grasper (118, 218) between a first position and a second position.
