Peritoneal distension robotic arm
First Claim
1. A positionable support structure adapted to be mounted on a table, said support structure comprising:
- an extendible vertical post having a lower end and an upper end and comprising plurality of telescoping vertical segments;
means for removably securing the lower end of the vertical post to the table;
an extendible arm extending generally horizontally from the vertical post and having a proximal end and a distal end, said proximal end being pivotally secured to the a distal end, said proximal end being pivotally secured to the upper end of the vertical post, whereby the horizontal arm can be rotated about an axis defined by the vertical post;
means for releasably locking the position of the horizontal arm relative to the vertical post; and
means for vertical extension and retraction of the vertical post while the horizontal arm remains locked relative to the vertical post.

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 peritoneal distension instruments to the distal end of the horizontal arm, and vertically extending the vertical post while the horizontal arm remains locked relative to the post, thereby distending the peritoneum of the patient.
