Abstract

A needle for use with an endoscopic stitching device includes a first end portion that is movable relative to a second end portion to allow the needle to convert from a first, mis-aligned orientation to a second, aligned orientation, thereby allowing the length of the needle in the aligned orientation to exceed the height of an end effector.

First claim

What is claimed is:

1. An endoscopic stitching needle comprising:
a first end portion configured to engage a first jaw member of an endoscopic stitching device; and
a second end portion configured to engage a second jaw member of an endoscopic stitching device;
the first end portion movable relative to the second end portion;
wherein the endoscopic stitching needle is configured to be separable from an endoscopic stitching device; and
wherein the first end portion is adapted to receive the second end portion, the first end portion and the second end portion supporting a compressible element configured to enable the first and second end portions to move between extended and compressed positions.

2. The needle of claim 1 , wherein the compressible element includes at least one of a spring or a gas.

3. An endoscopic stitching device, comprising:
an end effector including a first jaw member and a second jaw member, the first jaw member movable relative to the second jaw member between an open state and a closed state;
a needle removably coupled to the end effector and including a first end portion and a second end portion, the first end portion movable relative to the second end portion, each of the first and second end portions selectively engageable with one of the respective first and second jaw members of the end effector; and
wherein the first end portion is adapted to receive the second end portion, the first end portion and the second end portion supporting a compressible element configured to enable the first and second end portions to move between extended and compressed positions.

4. The endoscopic stitching device of claim 3 , wherein, in the closed state, the end effector defines a height measured between a bottom-most surface of the end effector and a top-most surface of the end effector, the needle defining a working length that is greater than the height of the end effector.

5. An endoscopic stitching needle comprising:
a first end portion configured to engage a first jaw member of an endoscopic stitching device; and
a second end portion configured to engage a second jaw member of an endoscopic stitching device;
the first end portion movable relative to the second end portion, the first end portion configured to receive the second end portion, the first and the second end portions supporting a compressible element configured to enable the first and second end portions to move between a first, compressed position and a second, extended position.
