An instrument for endoscopic surgery includes a shaft having active and inactive portions, the active portion being reciprocable relative to the inactive portion. First and second operative elements are pivoted to the inactive portion of the shaft along substantially the same longitudinal plane. A handpiece includes an active and inactive branch hinged together, movement of the active and inactive branches of the handpiece together or apart shifting the active portion of the shaft relative to the inactive portion of the shaft. |
