20140263570 | SURGICAL STAPLER WITH PARTIAL POCKETS - A surgical stapler includes a jaw assembly at a distal end connected to a handle assembly that is configured to control the stapler and actuate the deployment of staples. The surgical stapler successfully eliminates intermediate caming portions commonly known as pushers that are located between the staples and a translating slider. The staples are located in pockets at an angle such that the base of the staple is parallel to an angled caming surface of the slider. The translating slider comes into direct contact with staples during deployment as the slider moves through each staple pocket where staples are partially supported by recesses along the slider pathway. The staples are deployed at an angle against the anvil surface. Because there are no pushers, a great deal of space is saved resulting in a much smaller diameter surgical stapler that is particularly suitable for laparoscopic stapling applications. | 09-18-2014 |
