Detachable motor powered surgical instrument
A detachable motor-powered surgical instrument. The instrument may include a housing that includes at least one engagement member for removably attaching the housing to an actuator arrangement. A motor is supported within the housing for supplying actuation motions to various portions of a surgical end effector coupled to the housing. The housing may include a contact arrangement that is configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.
1. A surgical instrument removably couplable to an actuator arrangement, said surgical instrument comprising:
an end effector, comprising:
a first jaw; and
a second jaw movable relative to said first jaw between an open position and a closed position;
a drive system axially movable relative to said end effector between a starting position and an ending position;
a housing assembly operably couplable to the actuator arrangement, said housing assembly comprising:
an engagement member configured to operably couple said housing assembly to the actuator arrangement; and
a contact arrangement energizable independently of said housing assembly being coupled or decoupled to the actuator arrangement; and
a motor configured to drive said drive system, wherein said motor is supported by said housing assembly, and wherein said motor is prevented from being actuated by a power source if said housing assembly is not coupled to the actuator arrangement.
2. The surgical instrument of claim 1 , wherein said end effector further comprises a fastener cartridge comprising fasteners removably stored therein.
3. The surgical instrument of claim 1 , wherein the actuator arrangement is operably coupled to a tool holder of a robotic arm.
4. The surgical instrument of claim 1 , wherein said contact arrangement comprises first electrical contacts, and wherein said housing assembly comprises second electrical contacts configured to control the actuation of said motor.
5. The surgical instrument of claim 4 , wherein said second electrical contacts are configured to allow said first electrical contacts to transfer energy to said motor.
6. The surgical instrument of claim 1 , further comprising a threaded drive shaft operably coupled to said motor and said drive system, wherein the actuation of said motor is configured to drive said threaded drive shaft to move said drive system toward said ending position.
7. The surgical instrument of claim 1 , wherein said drive system is configured to position said second jaw relative to said first jaw.
8. A surgical instrument removably couplable to an actuator system, said surgical instrument comprising:
an end effector, comprising:
a first jaw; and
a second jaw movable relative to said first jaw between an open position and a closed position;
a drive system axially translatable relative to said end effector from a first position toward a second position;
a housing assembly operably couplable to the actuator system, said housing assembly comprising:
an engagement member configured to operably couple said housing assembly to the actuator system; and
first contacts energizable independently of said housing assembly being coupled or decoupled to the actuator system; and
a motorized system configured to actuate said drive system, wherein said motorized system is supported by said housing assembly, and wherein said motorized system is prevented from being energized by a power source absent said housing assembly being coupled to the actuator system.
9. The surgical instrument of claim 8 , wherein said end effector further comprises a fastener cartridge comprising fasteners removably stored therein.
10. The surgical instrument of claim 8 , wherein the actuator system is operably coupled to a tool holder of a robotic arm.
11. The surgical instrument of claim 8 , wherein said housing assembly further comprises second contacts configured to control actuation of said motorized system.
12. The surgical instrument of claim 11 , wherein said second contacts are configured to allow said first contacts to transfer energy to said motorized system.
13. The surgical instrument of claim 8 , further comprising a threaded drive shaft operably coupled to said motorized system and said drive system, wherein actuation of said motorized system is configured to drive said threaded drive shaft to translate said drive system toward said second position.
14. The surgical instrument of claim 13 , wherein said drive system is configured to position said second jaw relative to said first jaw.
15. A surgical instrument removably couplable to an actuator arrangement, said surgical instrument comprising:
an end effector, comprising:
a first jaw; and
a second jaw rotatable relative to said first jaw between an open position and a closed position;
a drive system translatable relative to said end effector from a proximal position toward a distal position;
an enclosure operably couplable to the actuator arrangement, said enclosure comprising:
an engagement member configured to operably couple said enclosure to the actuator arrangement; and
contacts energizable independent of said enclosure being coupled or decoupled to the actuator arrangement; and
a motor configured to translate said drive system, wherein said motor is supported by said enclosure, and wherein said motor is unable to translate said drive system based on said enclosure being decoupled from said actuator arrangement.
16. The surgical instrument of claim 15 , wherein said end effector further comprises a fastener cartridge comprising fasteners removably stored therein.
17. The surgical instrument of claim 15 , wherein the actuator arrangement is operably coupled to a tool holder of a robotic arm.
18. The surgical instrument of claim 15 , wherein said contacts comprise first contacts, and wherein said enclosure further comprises second contacts configured to control actuation of said motor.
19. The surgical instrument of claim 18 , wherein said second contacts are configured to allow said first contacts to transfer energy to said motor.
20. The surgical instrument of claim 15 , further comprising a threaded drive shaft operably coupled to said motor and said drive system, wherein actuation of said motor is configured to drive said threaded drive shaft to move said drive system toward said distal position.
