Surgical stapling (surgical stapling) and cutting mechanism is through the surgical opening, in particular, the position over the cannula of the trocar (trocar) in the handle and an elongate shaft upper and lower tank (jaw) (i.e., anvil and staple channel) by having a surgical procedure allows a minimal infringement. A pair of fluid bladder (bladder) (lift bag; lift bag) is positioned within the staple channel below the lever projecting proximally, thus, the transfer of fluid from the handle causes closing and clamping of the anvil. Two-way fluid control may be mechanically generated in the handle or by activating an electroactive polymer actuators (electroactive polymer actuator). Once trigger is detected, EAP plunger medical materials in the medical substance syringe inserted into the elongate shaft is activated to dispense [e.g., anesthetics, adhesives, cauterizing substances (cauterizingg substance) antibiotics, etc.], material on the incision during tissue a is guided along a percussion bar (firing bar) the cleavage plane of the E- beam to place. Handle, an elongate shaft, the end-effector, percussion member, a control circuit, a surgical instrument.
