The surgical stapling device of claim 1 wherein said swing arm member includes a reset tab element to engage said clamp lock member to reset said clamp lock member and said reset tab element also configured to engage said deploy release member. A surgical stapling device, comprising: a mode switch member to select a drive assembly to a deployment mode; a trigger member to activate said drive assembly to advance a deployment assembly to staple and cut a target tissue; a deployment slide member to advance said deployment assembly in a first direction to drive both a wedge assembly to deploy staples into said target tissue and a knife member to cut said target tissue; and a swing arm member with a reset tab element to release a clamp lock to unclamp a jaw assembly to release said target tissue and to reset said mode switch member to a neutral state to disengage said drive assembly from the deployment mode. A surgical stapling device, comprising: a mode switch member to select a drive assembly to a deployment mode; a trigger member to activate said drive assembly to advance a deployment assembly to staple a target tissue; a deployment slide member to advance said deployment assembly in a first direction to drive a wedge assembly to deploy staples into said target tissue; and a swing arm member with a reset tab element to release a clamp lock to unclamp a jaw assembly to release said target tissue and to reset said mode switch member to a neutral state to disengage said drive assembly from the deployment mode. A method of stapling and cutting tissue by a surgical stapling device, comprising: setting a mode switch member to select a drive assembly to a deployment mode; activating a trigger member to drive said drive assembly; advancing a deployment slide member of a deployment assembly; urging forward by the deployment assembly a wedge assembly to deploy staples in a target tissue; urging forward by the deployment assembly a knife member to cut said target tissue; and placing a swing arm member with a reset tab element in a first reset position to release a clamp lock to unclamp a jaw assembly. The method of claim 5 , further comprising: placing said swing arm member in a second reset position to release a deployment release member to reset said mode switch member to a neutral state to disengage said drive assembly from deployment. A surgical stapling device, comprising: a handle assembly; a shaft assembly coupled to the handle assembly; and an end-effector coupled to the shaft assembly, wherein the end-effector comprises: a jaw assembly configured to clamp, staple, and cut a target tissue, wherein the handle assembly comprises: a trigger element to activate a drive assembly to advance a deployment assembly to staple and cut said target tissue, wherein the deployment assembly comprises: a deployment slide member to either advance said deployment assembly in a first direction or retreat said deployment assembly in a second direction, and a reset switch member configured to retreat said deployment assembly to a first reset position causing an unclamp tab element of a swing arm member to release a clamp lock member from a clamp lock state. The surgical stapling device of claim 7 , wherein said reset switch further configured to retreat said swing arm member without displacing said deployment assembly to cause said unclamp tab element to engage a deployment release member to reset a mode switch member from a deployment mode. A surgical stapling device, comprising: a mode switch member to select a drive assembly to a deployment mode; a trigger member to activate said drive assembly to advance a deployment assembly to staple and cut a target tissue; a deployment slide member to advance said deployment assembly in a first direction to drive both a wedge assembly to deploy staples into said target tissue and a knife member to cut said target tissue; and a reset switch member to place a swing arm member with a reset tab element in a first reset position to release a clamp lock member to unclamp a jaw assembly to release said target tissue. The surgical stapling device of claim 9 , wherein the reset switch member further places the swing arm member in a second reset position without causing displacement of the deployment assembly to release a deployment reset member. A surgical stapling device, comprising: a mode switch member to select a drive assembly to a deployment mode; a trigger member to activate said drive assembly to advance a deployment assembly to staple a target tissue; a deployment slide member to advance said deployment assembly in a first direction to drive a wedge assembly to deploy staples into said target tissue; and a reset switch member to place a swing arm member with a reset tab element in a first reset position to release a clamp lock member to unclamp a jaw assembly to release said target tissue. The surgical stapling device of claim 11 , wherein the reset switch member further place the swing arm member in a second reset position without causing displacement of the deployment assembly to release a deployment reset member. A method of stapling and cutting tissue by a surgical stapling device, comprising: setting a mode switch member to engage a drive assembly to a deployment mode; activating a trigger member to drive said drive assembly; advancing a deployment slide member of a deployment assembly; urging forward by the deployment assembly a wedge assembly to deploy staples in a target tissue; urging forward by the deployment assembly a knife member to cut said target tissue; and placing a swing arm member with a reset tab element in a first reset position to release a clamp lock to unclamp a jaw assembly. The method of claim 13 , further comprising: placing said swing arm member in a second reset position, without causing displacement to the deployment assembly, to release a deployment release member to reset said mode switch member to a neutral state to disengage said drive assembly from deployment. The method of claim 14 , further comprising: placing said swing arm member in a second reset position release a clamp lock to unclamp a jaw assembly to disengage said target tissue. A surgical stapling device, comprising: a handle assembly; a shaft assembly coupled to the handle assembly; and an end-effector coupled to the shaft assembly, wherein the end-effector comprises: a jaw assembly configured to clamp, staple, and cut a target tissue, wherein the handle assembly comprises: a trigger element to activate a drive assembly to advance a deployment assembly to staple and cut said target tissue, wherein the deployment assembly comprises: a deployment slide to either advance said deployment assembly in a first direction or retreat said deployment assembly in a second direction, and a reset switch member configured to retreat said deployment assembly to a first reset position causing an unclamp tab element of a swing arm member to engage a deployment release member to reset a mode switch button from a deployment mode. The surgical stapling device of claim 16 , wherein said reset switch further configured to retreat said swing arm member to cause said unclamp tab element to engage a clamp lock member from a clamp lock state to release said jaw assembly from a clamped state.
