Abstract

A surgical clamp includes a support frame clamp member, a retraction shaft clamp member and a handle linked to the support frame clamp member and the retraction shaft clamp member for moving the clamp members between loosened and tightened positions. Both the support frame clamp member and the retraction shaft clamp member permit transverse attachment. The shaft clamp and the support frame permit pivoting of the retraction shaft relative to the support frame. The handle is always in alignment with the retractor shaft, with a gripping portion extending above and in line with the shaft but attached to the clamp below the shaft. With this clamp and handle configuration, the clamp maintains a very low profile while still allowing easy access to the handle from above during the tightening and/or loosening motions, permitting a single handed “scissors action” tightening.

Claims19

Dependent claims

A surgical clamp comprising:

a first clamp member having a frame rod opening for receiving a support frame rod, the frame rod opening being accessible for transverse application onto the first rod, the frame rod opening defining a frame rod opening axis;
a second clamp member having a retractor rod opening for receiving a retractor rod, the retractor rod opening being accessible for transverse application of the retractor rod into the retractor rod opening at an orientation wherein the retractor rod extends in a retractor rod plane above the frame rod, with the retractor rod plane being defined parallel to the frame rod opening axis and the retractor rod opening defining an axis within the retractor rod plane, the second opening changing dimensions to receive the retractor rod in a loosened second clamp position and in a tightened second clamp position, the second clamp member being attached to the first clamp member;
a handle having a handle linkage for moving the second clamp between its loosened second clamp position and its tightened second clamp position, the handle linkage coupled to the second clamp at a position below the retractor rod plane, the handle having a grip portion which is above the retractor rod plane in both the loosened second clamp position and in the tightened second clamp position.

A surgical clamp comprising:

a first clamp member having a first rod opening for receiving a first rod, the first opening changing dimensions to receive the first rod in a loosened first clamp position and in a tightened first clamp position;
a second clamp member having a second rod opening for receiving a second rod, the second opening changing dimensions to receive the retractor rod in a loosened second clamp position and in a tightened second clamp position, the second clamp member being attached to the first clamp member;
a handle having a handle linkage both for moving the first clamp between its loosened first clamp position and its tightened first clamp position and for moving the second clamp between its loosened second clamp position and its tightened second clamp position, the handle linkage comprising:
a cam member biasing off a bearing surface about a cam center plane, the cam member pivotally rotating about a cam axis;
a shaft portion extending along the cam axis off a single side of the cam member for applying torque to rotate the cam member;
and
a handle extension extending to grip portion, the handle extension being bent such that the grip portion extends through or within the cam center plane.
