Abstract
A clamping device includes a first clamping member and a second clamping member that are pivotally mounted with respect to each other. The first clamping member is fabricated from a unitary structure. The first clamping member has a first clamping end, a second clamping end, and a first fulcrum portion located between the first clamping end and the first attachment end.
Claims19
A clamping device comprising:
- a first clamping member fabricated from a unitary structure, wherein the first clamping member has a first clamping end, a first attachment end, and a first fulcrum portion located between the first clamping end and the first attachment end;
- and
- a second clamping member pivotally mounted with respect to the first clamping member so that the second clamping member engages the first clamping member proximate to the first attachment end, wherein the second clamping member is fabricated from a unitary structure, and wherein the second clamping member has a second clamping end, a second attachment end, and a second fulcrum portion located between the second clamping end and the second attachment end.
A clamping device comprising:
- a first clamping member fabricated from a unitary structure, wherein the first clamping member has a first clamping end, a first attachment end, and a first fulcrum portion located between the first clamping end and the first attachment end;
- and
- a second clamping member fabricated from a unitary structure, wherein the second clamping member has a second clamping end, a second attachment end, and a second fulcrum portion located between the second clamping end and the second attachment end, and wherein the second clamping member is pivotally mounted with respect to the first clamping member so that the second clamping member engages the first clamping member proximate to the first attachment end.
A clamping device for use in conjunction with a retractor support apparatus, the clamping device comprising:
- a first clamping member having:
- a first clamping surface formed therein;
- and
- a first fulcrum portion;
- and
- a second clamping member having:
- a second clamping surface formed therein;
- and
- a second fulcrum portion;
- wherein the first and second clamping members are pivotally mounted together so that:
- the first fulcrum portion is between the first clamping surface and a point at which the first clamping member pivotally mounts to the second clamping member;
- and
- the second fulcrum portion is between the second clamping surface and a point at which the second clamping member pivotally mounts to the second clamping member.
A clamping device for use in a retractor support having a cylindrical shaped support portion, the clamping device comprising:
- a first clamping member having a first clamping surface formed therein;
- and
- a second clamping member having a second clamping surface defining a clamping slot, wherein the clamping slot is configured to receive the cylindrically shaped support portion of the retractor support and wherein the second clamping member further includes a spring element for securing the second clamping member onto the cylindrically shaped support portion of the retractor support with sufficient force to retain the clamping member in a selected rotational position with respect to the retractor support.
