A surgical stapling or fastening instrument for applying surgical staples or fasteners to tissue having a controlled closure mechanism to approximate the distance between the jaw members of the instrument. The controlled closure mechanism consists of a catch member having a resilient material secured thereto which engages a pivotable lance member which freezes the rotation of the catch member at an infinite number of desired locations along its path of rotation. Controlling the position of the catch member controls the distance between the jaw members of the stapling or fastening device.
