摘要：
A circular stapler includes a staple body and an anvil assembly. The staple body includes an annular staple cartridge and an annular cutter located at a distal end thereof. The anvil assembly includes an annular anvil, an annular cutting pad and an anvil shaft. When the staple body and the anvil assembly are closed, the annular staple cartridge is associated with the annular anvil and the annular cutting pad to form at least two connected fixing spaces having height difference. The circular stapler facilitates fixing the severed staples for easily cutting. A buffer may be formed between the tissues near the new formed staples and the tissue near the severed staples in order to avoid or reduce lateral slipping, thereby reducing dragging the tissues on the end face of the anvil.
