Abstract
A positioning apparatus for use in surgical operating procedures and the like comprising a universal positioner which may be adjustably positioned along a support bar suspended from and substantially rigidly connected to an operating table or the like. The positioning apparatus includes a ball and circular jaw coupling including spaced apart clamp blocks having upper and lower clamp rings for forcibly engaging the ball in response to the urging of a plurality of compression springs. A lever actuated cam connected to a foot pedal is operable to release the biasing force on the support blocks whereby the position of the support arm connected at one end to the ball may be finely adjusted over a wide range of positions.
