Abstract
A surgical instrument including a handle portion, a body portion, a movable handle, a tool assembly, a drive beam and a closure apparatus is disclosed. At least one of the closure apparatus and a contact surface of the tool assembly include a plastic surface. The body portion extends distally from the handle portion. The movable handle is located on the handle portion and is in mechanical cooperation with a drive member. The tool assembly includes an anvil, a cartridge assembly and a contact surface. The drive beam includes a proximal engagement portion and is configured to engage a portion of the drive member. The closure apparatus is configured to engage the contact surface of the tool assembly. At least a partial actuation of the movable handle moves the closure apparatus distally into engagement with the contact surface to approximate the anvil and the cartridge assembly.

- A surgical instrument, comprising;
a body portion; a drive member extending through the body portion; a tool assembly positioned at a distal end of the body portion, the tool assembly including an anvil assembly and a cartridge assembly which are repositionable in relation to each other; and a closure apparatus operably connected to the drive member and including a pair of end portions of metallic construction configured and dimensioned to engage the anvil assembly and the cartridge assembly, whereby movement of the drive member effectuates distal advancement of the closure apparatus to move the tool assembly towards the closed position, the closure apparatus further including an intermediate portion positioned between the end portions and a cap member of non-metallic construction associated with at least one end portion to minimize friction between a metallic portion of the closure apparatus and a metallic portion of the tool assembly during distal movement of the closure apparatus, the cap member including a reinforced section extending at least partially into the intermediate portion to reduce inadvertent disconnection of the cap member from the end portion.
