Abstract
The invention provides an apparatus and method for manipulating parts of the body in surgical procedures, particularly useful for peritoneal distension in laparoscopic surgery. The apparatus comprises a positionable support structure having an extendible horizontal arm rotatably mounted to an extendible vertical post, the post having a clamp at its lower end for mounting to a surgical table. An end segment at the distal end of the horizontal arm has a mount for mounting end-of-arm tooling, for example, peritoneal distension instruments. Locking mechanisms are disposed in the horizontal arm, vertical post and end segment to lock the support structure in a desired position. A motor is disposed within the vertical post for power-assisted extension and retraction of the vertical post. Preferably, the locking mechanisms and motor are controllable using switches mounted on the end segment. The method comprises providing a support structure as described mounted to a surgical table, positioning the distal end of the horizontal arm over a patient on the table, activating locking mechanisms in the horizontal arm and vertical post to lock the support structure in position, attaching peritonea…
