Abstract

A surgical clamp in certain embodiments may be configured to operate with a surgical installation tool. The clamp may have two elongated members with a bight portion that joins the two elongated members at a proximal end of the clamp and that may bias the two elongated members in an open position at a distal end. The bight portion may have one or more engagement features, such as a slotted aperture or other engagement or coupling feature. A clasp mechanism at the distal end of the clamp may have a male or first component disposed on or adjacent one of the two elongated members and a female or second component disposed on or adjacent the other of the two elongated members at the distal end of the clamp. The installation tool may include an elongated member with a proximal end and a distal end that has an engagement feature to engage the clamp, such as at the bight portion. A handle in one embodiment may be provided at the proximal end of the installation tool, while a head at the distal end may be configured to receive and/or engage the proximal end of the clamp and may also be operable to articulate in at least one plane.

Claims

1. A surgical clamp comprising:

at least two elongated members each having an elongated length, wherein at least one surface of the at least two elongated members has a padding material positioned adjacent at least a portion of the surface;

a bight portion joining said two elongated members at a proximal end of the surgical clamp and biasing said two elongated members in an open position at a distal end of the surgical clamp, wherein said bight portion has an exterior surface, an interior surface, and at least one engagement feature provided therein, wherein the at least one engagement feature of the bight portion includes at least one opening formed in the bight portion, and wherein the at least one opening of the bight portion extends from the exterior surface to the interior surface; and

a clasp mechanism having a male component disposed on one of the two elongated members at the distal end of the surgical clamp and a female component disposed on the other of the two elongated members at the distal end of the surgical clamp.

2. The surgical clamp of claim 1, wherein the at least two elongated members are attached to elongated members of a spring component that serves as the bight portion.

3. The surgical clamp of claim 2, wherein the spring component includes steel.

4. The surgical clamp of claim 2, wherein the at least two elongated members of the surgical clamp are attached to interior surfaces of the elongated members of the spring component by welding.

5. The surgical clamp of claim 2, wherein the elongated members are comprised of titanium, and a surface of the at least two elongated members of the surgical clamp is curved and contacts at least one of the elongated members of the spring component.

6. The surgical clamp of claim 1, wherein spacing between the interior surfaces of said at least two elongated members includes a partition forming section located nearer the distal end of the surgical clamp than the proximal end of the surgical clamp, and a passage forming section located nearer the proximal end of the surgical clamp than the distal end of the surgical clamp.

7. The surgical clamp of claim 6, wherein the bight portion includes a spring portion that serves at least partially as the passage forming section.

8. The surgical clamp of claim 7, wherein said padding material is connected to at least one of the two elongated members at least at a location on the surface corresponding to at least part of the partition forming section.

9. The surgical clamp of claim 8, wherein the padding material is comprised predominantly of silicone.

10. The surgical clamp of claim 1, wherein the at least one opening formed in the bight portion comprises a slotted aperture having a width and a length, wherein the length is greater than the width.

11. The surgical clamp of claim 10, wherein the length of the slotted aperture is oriented perpendicular to a longitudinal axis of the surgical clamp.

12. The surgical clamp of claim 1, wherein the male component of the clasp mechanism corresponds to an end of the elongated member that flares away from a longitudinal axis of the surgical clamp when the surgical clamp is placed in a closed position.

13. The surgical clamp of claim 12, wherein the female component of the clasp mechanism corresponds to a loop disposed to engage the end of the elongated member when the surgical clamp is placed in the closed position, and a hinge formation engaging the loop has a detent distally positioned to retain the loop in a plane parallel to a plane in which a longitudinal axis of the clamp predominately lies when the clamp is closed.
