Surgical system

1. A surgical system for treating patient tissue, comprising:

an elongate shaft comprising a longitudinal axis;

a stapling head coupled to the elongate shaft and configured to perform the following operations:

clamp the patient tissue;

staple the patient tissue;

rotate about the longitudinal axis of the elongate shaft; and

articulate relative to the elongate shaft; and

a rigid housing assembly coupled to the elongate shaft and comprising four or more rotary disc members configured to be driven by a robotic surgical device, wherein each rotary disc member is rotatable about an axis, and wherein at least one of the four or more rotary disc members is configured to rotate more than a full rotation about its axis to generate one of the stapling head operations.

2. The surgical system of claim 1 , further comprising a firing member operably coupled to one of the rotary disc members.

3. The surgical system of claim 2 , wherein the firing member comprises a cutting portion.

4. A surgical system for use with a robotic surgical device, wherein said surgical system comprises:

an elongate shaft assembly comprising a longitudinal axis;

a jaw assembly coupled to and extending from the elongate shaft assembly, wherein the jaw assembly is movable between an unclamped configuration and a clamped configuration, wherein the jaw assembly is configured to support a staple cartridge comprising staples removably stored therein, wherein the jaw assembly is configured to eject the staples from the staple cartridge, wherein the jaw assembly is configured to rotate about the longitudinal axis, and wherein the jaw assembly is configured to articulate relative to the elongate shaft assembly; and

a rigid housing, wherein the elongate shaft assembly is coupled to and extends from the housing, wherein the housing comprises at least four rotary disc members configured to be driven by the robotic surgical device, and wherein at least one of the at least four rotary disc members is configured to rotate at least one complete rotation to operate the jaw assembly.

5. The surgical system of claim 4 , wherein the jaw assembly comprises the staple cartridge.

6. The surgical system of claim 5 , wherein the staple cartridge comprises a replaceable staple cartridge.

7. The surgical system of claim 4 , further comprising a firing member coupled to one of the at least four rotary disc members.

8. The surgical system of claim 7 , wherein the firing member comprises a cutting portion.

9. A surgical system for use with a robotic surgical system, comprising:

a stapling head;

an elongate shaft coupled to the stapling head; and

a rigid housing coupled to the elongate shaft, wherein the housing comprises a first rotary disc member, a second rotary disc member, a third rotary disc member and a fourth rotary disc member, wherein each of the rotary disc members are configured to be driven by the robotic surgical system, wherein each rotary disc member is rotatable about a different axis to operate the stapling head, and wherein the first rotary disc member is configured to rotate more than a complete rotation about its axis to operate the stapling head.

10. The surgical system of claim 9 , wherein the stapling head is configured to perform the following operations:

clamp patient tissue;

staple patient tissue;

rotate about a longitudinal axis of the elongate shaft; and

articulate relative to the elongate shaft.
