A surgical stapler includes a stapler head with a stapler cartridge from which staple blanks are ejected against an anvil with grooves that bend the staple blanks into staples that hold together tissue layers interposed between the anvil and stapler cartridge. The anvil and stapler head each includes magnetic members, at least one of which is a magnet and the other of which is either another magnet or a non-magnetized magnetically permeable member. Placing the anvil and stapler head in proximity with each other causes them to be magnetically coupled together with the anvil opposing the stapler cartridge. The anvil is then locked to the stapler head mechanically so that the tissues captured therebetween can be secured together by actuating the stapler to eject staple blanks against the anvil. In another aspect of the invention, the staple cartridge is removably secured to the stapler head by a similar magnetic arrangement.
