Abstract

See full text

A normally closed clamp is provided which is formed from two extruded elements which are connected together in their midregion by means of a non-circular cam on a base element and a corresponding non-circular cam surface on a clamping element. In the normally closed position, the cam and cam surface urge the device into a jaw-closed position with the handles being spaced-apart. When the handles are brought together, the jaw members separate and the relative position of the cam surface and the cam member is altered. The device may be used as a tissue separator. Two of the devices may be assembled together as a tendon approximator.
