Abstract

A surgical instrument includes an end effector having a clevis and first and second jaws mutually rotatable between open and closed positions. The jaws are proximally directed and laterally displaced relative to a longitudinal axis of a control shaft of the instrument. The jaws hold first and second parts of a fastener, respectively. The first part includes a base having upstanding tissue piercing posts, and the second part includes another base defining apertures for receiving the posts, as well as a portion movable relative to the second base. When the upstanding posts are inserted into the apertures, the movable portion can be moved into a second configuration to lock the parts of the fastener together. The instrument is adapted to move the second part into the second configuration. A method for using the apparatus and fastener are also provided.

Claims

1. A surgical fastener, comprising:

a) a first part including a first base provided with at least one stiff upstanding tissue piercing post having at least one groove; and

b) a second part including;

a second base defining an aperture for receiving each of said at least one stiff upstanding tissue piercing post; and

a movable portion movable relative to said second base between first and second configurations, engaging with said at least one post in said second configuration, and including a catch engaging said at least one groove when said movable portion and said second base are in said second configuration,

wherein when said movable portion is in said first configuration and said at least one stiff upstanding post is inserted into a respective aperture, movement of said movable portion into said second configuration locks said first part relative to said second part.

2. The surgical fastener according to claim 1, wherein:

said movable portion and second base are movable from said second configuration into said first configuration to unlock said first part relative to said second part.

3. The surgical fastener according to claim 1, wherein:

said at least one post is adapted to assume a position in which said at least one posts extends substantially perpendicular to said first base.

4. The surgical fastener according to claim 1, wherein:

said movable portion is slidable relative to said second base.

5. The surgical fastener according to claim 1, wherein:

said catch is spring-biased.

6. The surgical fastener according to claim 1, wherein:

each of said at least one post includes a tip;

said movable portion includes a first cover portion;

said second base includes a second cover portion; and

when said at least one post is received through respective apertures in said second base, said first and second cover portions shield said tips of said at least one post when said second base and said movable portion are in said second configuration.
