A surgical stapler apparatus.

摘要

The end-to-end anastomosis apparatus is provided with a mounting means (17) which can receive a trocar (33) for making holes in tissue and, subsequently, an anvil shaft (13) for the mounting of an anvil assembly (16) for stapling purposes. The anvil shaft is provided with splines (47) which co-operate with splines (46) on a shell liner (19) within the housing of the apparatus to align the buckets (49) on the anvil assembly with the staples (24) in a cartridge (23) secured in the apparatus. In addition, the anvil assembly is provided with a spring (57) for locking of the anvil housing on the anvil shaft.
