Method for use when performing end-to-side anastomosis and anastomosis instrument

摘要

A method of establishing end-to-end anastomosis using a device (501) having a bypass channel passageway (502D) terminated by a peripheral anvil (502A, 503B), the end of a bypass channel Such as the coronary artery, and then the tissue edges to be joined are first clamped together by the clamping slide 505 and then stapled together by the stapling plunger 506 A major novel feature is that the stapling plunger 506 is arranged not to be parallel to the passage 502D but to move at an angle relative to its passage. With this arrangement, it is possible to use a greater number of staples than was possible in the prior art methods. Preferably, the mechanism is adapted to be separated in the longitudinal direction of the passage 502D.
