Fulcrum wedge clamp
View Patent ↗A surgical joint includes a first clamping member comprising a first clamping surface for engaging a first surgical rod and an attachment end. A second clamping member is mounted with respect to the first clamping member wherein the second clamping member comprises a second clamping surface for engaging a second surgical rod. A shaft is disposed through and positioned within the attachment end of the first clamping member and wherein the shaft is in communication with the second clamping member. A force providing mechanism is disposed between the first and second clamping members and disposed about the shaft wherein when the force providing mechanism and the shaft are movable with respect to each other and place the first and second clamping members in either a non-clamping position or a clamping position.
1. A surgical joint comprising:
a first clamping member comprising a first clamping surface for engaging a first surgical rod and an attachment end;
a second clamping member mounted with respect to the first clamping member wherein the second clamping member comprises a second clamping surface for engaging a second surgical rod;
a shaft disposed through and positioned within the attachment end of the first clamping member and wherein the shaft is in communication with the second clamping member; and
a camming mechanism having a handle fixedly attached thereto and wherein the camming mechanism directly contacts an external surface of the handle and wherein the camming mechanism is disposed between the first and second clamping members and disposed about the shaft wherein when the camming mechanism and the shaft are movable with respect to each other to position the first and second clamping members in either a non-clamping position or a clamping position by gripping and applying a manual force to the handle.
2. A low profile surgical clamp mounted to a retractor support apparatus comprising:
a first clamping member for engaging the retractor support apparatus and an attachment end;
a second clamping member for engaging a retractor and being mounted with respect to the first clamping member;
a shaft extending through the attachment end of the first clamping member;
an actuating mechanism having a camming surface engaging the shaft and positioned between the first and second clamping members wherein the actuating mechanism is movable to position the first and second clamping members between a nonclamping position and a clamping position; and
a handle fixedly connected to the actuating mechanism and wherein the actuating mechanism directly contacts an external surface of the handle.
3. A surgical clamp for clamping surgical devices, the clamp comprising:
a clamping member with a clamping cavity;
a pin extending through the clamping member and into the clamping cavity; and
a camming mechanism that moves the pin within the cavity placing the clamping member in a clamping position.
4. The surgical clamp of claim 3 and further comprising a spring that biases the pin into the clamping cavity.
