摘要:
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.
