Abstract: An adjustable height field post includes an inner shaft and an outer tube configured to receive and slidably engage the inner shaft. A clamp body is provided at one end of the inner shaft such that the field post can be securely attached to an operating table. An adjustment mechanism is incorporated into the inner shaft and the outer tube such that the height of the field post can be adjusted to accommodate various working conditions and also prevent any portion of the same from extending beyond an upper most attached post coupling.

Abstract: A laparoscopic retractor comprises a shaft having a distal end, a proximal end and a channel extending longitudinally from the distal end to the proximal end, and a handle connected to the proximal end of the shaft and having a longitudinal channel therethrough. There are a plurality of links pivotally connected in a linear arrangement, with one of the links connected to the distal end of the shaft. Each link has a longitudinal channel therethrough. The shaft and links form a continuous line terminating in a tip formed by an end link. There is a cable extending from the tip through the channels in the links, shaft and handle and an adjustment mechanism connected to the handle opposite the shaft and connected to the cable. There is spring mounted between the handle and adjustment mechanism to bias movement of the adjustment mechanism relative to the handle.

Abstract: An instrument holder which provides rapid and secure positioning of any diameters of laparoscopic instruments through the use of a specially designed grid in a cantilevered-style rack by employing, in a preferred embodiment, a pair of double swivel-ball locking positioners with an adjustable clamp for securement to an operating room table rail, with the grid having front and rear sides having upwardly and downwardly extending holding bars, respectively, of spaced notch segments between which the cannulas of the instruments extend, in adjusting the angle and attitude of the grid and instruments, and the height of the instruments about and above the surgical field.

Abstract: An abdominal wall elevator device including a pair of retractable tabs rotatable to 90.degree. with respect to the vertical axis of the device, and selected of a dimension to enter the port of a Trocar in allowing low pressure pneumoperitoneum laparoscopic surgery. In a preferred embodiment of the invention, a removable push-rod incorporates a flat tip to operate on the tenons of a pair of hinges to swing the retractor tabs to the desired angle, to be locked in place.
