Abstract

A medical device includes a clevis, a first jaw, and a second jaw. The first jaw includes a first proximal gripping portion and a first distal gripping portion, and the first proximal gripping portion includes a first needle alignment portion. The second jaw is coupled to the clevis and includes a second proximal gripping portion and a second distal gripping portion, and the second proximal gripping portion includes a second needle alignment portion. The first and second needle alignment portions are located opposite each other when in the closed orientation. The first and second needle alignment portions define a clamp path when in the closed orientation within which the curved portion of the needle is received when the second jaw is in the open orientation. The first and second needle alignment portions are configured to rotate the needle when moving to the closed orientation.

First claim

What is claimed is:

1. An apparatus, comprising:
a clevis;
a first jaw coupled to the clevis, the first jaw including a first clamp support; and
a second jaw coupled to the clevis, the second jaw including a second clamp support, wherein:
at least one of the second jaw and the first jaw is movable relative to the other of the second jaw and the first jaw about a rotation axis between an open orientation and a closed orientation,
the first clamp support is rotatably fixed relative to the first jaw about a first axis orthogonal to each of a longitudinal axis and the rotation axis,
the second clamp support is rotatably fixed relative to the second jaw about a second axis orthogonal to each of the longitudinal axis and the rotation axis,
the second clamp support is displaced distally relative to the first clamp support on a condition that the first jaw and the second jaw are in the closed orientation,
the second clamp support and the first clamp support define a clamp path on the condition that the first jaw and the second jaw are in the closed orientation,
the clamp path has a path radius of curvature,
the clamp path lies within a lateral plane with respect to the longitudinal axis,
the lateral plane defines an oblique angle with the longitudinal axis and includes an axis that is parallel to the rotation axis,
the first clamp support and the second clamp support are configured to retain a needle in a needle orientation on the condition that the first jaw and the second jaw are in the closed orientation, and
the needle orientation extends along the clamp path in the lateral plane at an angle to the longitudinal axis either distally along the longitudinal axis or proximally along the longitudinal axis.

2. The apparatus of claim 1 , wherein:
the needle includes a first needle end portion, a second needle end portion and a curved portion between the first needle end portion and the second needle end portion, the first clamp support and the second clamp support engaging the needle and retaining the needle along the curved portion and the first needle end portion, and the second needle end portion extend at an angle to and distally along the longitudinal axis.

3. The apparatus of claim 2 , wherein:
the first clamp support and the second clamp support are configured to orient the needle received between the first clamp support and the second clamp support by clamping on the curved portion of the needle when the second jaw moves from the open orientation to the closed orientation to align the curved portion of the needle with the clamp path, and the curved portion of the needle is located within the needle orientation.

4. The apparatus of claim 3 , wherein:
the first clamp support comprises a pair of lateral clamp members laterally spaced apart from each other on the first jaw with respect to the longitudinal axis;
the second clamp support comprises a central clamp member located on the longitudinal axis; and
the pair of lateral clamp members and the central clamp member define the clamp path when the first jaw and the second jaw are in the closed orientation.

5. The apparatus of claim 4 , wherein:
the pair of lateral clamp members and the central clamp member are configured to orient the needle distally along the longitudinal axis.

6. The apparatus of claim 4 , wherein:
the pair of lateral clamp members and the central clamp member are configured to orient the needle proximally along the longitudinal axis.

7. The apparatus of claim 4 , wherein:
the central clamp member comprises a peaked clamp surface, the peaked clamp surface comprising a central peak and adjacent lateral surfaces, the central peak being located closer to the first jaw when in the closed orientation than the adjacent lateral surfaces; and
each of the pair of lateral clamp members comprises an inwardly angled clamp surface, an outer side of each inwardly angled clamp surface being closer to the second jaw when in the closed orientation than a corresponding inner side of each inwardly angled clamp surface.

8. The apparatus of claim 1 , wherein:
the first clamp support is a first distal clamp support, the second clamp support is a second distal clamp support, the clamp path is a distal clamp path, the needle orientation is a distal needle orientation; and
the apparatus further comprises a first proximal clamp support and a second proximal clamp support.

9. The apparatus of claim 8 , wherein:
the second proximal clamp support is located opposite and offset from the first proximal clamp support along the longitudinal axis when the first jaw and the second jaw are in the closed orientation;
the first proximal clamp support and the second proximal clamp support are configured to retain the needle in a proximal needle orientation when the first jaw and the second jaw are in the closed orientation; and
the first proximal clamp support and the second proximal clamp support define a proximal clamp path having a proximal path radius of curvature.

10. The apparatus of claim 9 , wherein:
the distal needle orientation includes an upward orientation configured to retain a curved portion of the needle within a first axial plane intersecting the longitudinal axis of the first and the second jaws when in the closed orientation, and a center of a distal clamp path radius of curvature being located on a side of the first jaw opposite from the second jaw.

11. The apparatus of claim 10 , wherein:
the proximal needle orientation includes a downward orientation configured to retain the curved portion of the needle within a second axial plane intersecting the longitudinal axis of the first and the second jaws when in the closed orientation, a center of a proximal clamp path radius of curvature being located on a side of the second jaw opposite from the first jaw.

12. The apparatus of claim 1 , wherein:
the first clamp support has a first apex line defined by a first ramped surface and a second ramped surface; the second clamp support has a second apex line defined by a third ramped surface and a fourth ramped surface; and
the first apex line is spaced apart from the second apex line by an offset distance along the longitudinal axis.

13. The apparatus of claim 12 , wherein:
the first apex line is orthogonal to the longitudinal axis; and
the second apex line is orthogonal to the longitudinal axis.

14. The apparatus of claim 1 , wherein:
the second jaw and the first jaw are movable relative to each other about the rotation axis between the open orientation and the closed orientation.

15. The apparatus of claim 1 , wherein:
the first clamp support is monolithically constructed with the first jaw; and
the second clamp support is monolithically constructed with the second jaw.
