Abstract
A laparoscopic stapler with a blocking body is disclosed. The blocking body allows the stapler to be inserted into the abdominal cavity through a cannula and removed therefrom until the staples are fired. When the staples are fired, the blocking body allows the stapler to be removed from the abdominal cavity of the patient through the cannula. After the staples have been fired and the stapler is removed from the abdominal cavity, the blocking body is in a blocking position where it then prevents the stapler from being reinserted through the cannula.
