摘要
A surgical instrument includes a body portion, a shaft, and an end effector that is operable to compress, staple, and cut tissue. The end effector includes and anvil and a staple cartridge. The anvil has a body and a modular releasable curved tip that connects with the body. The curved tip may be elastically deformable. The curved anvil tip and the tip of the cartridge include cooperating features that assist in gripping tissue during clamping. A separate cartridge may be provided that retains a replacement anvil tip and a replacement staple cartridge, where the replacement anvil tip and staple cartridge include the cooperating features. The separate cartridge may also include anvil tip and staple cartridge removal features to assist in removal of previously installed anvil tips and staple cartridges.
