Research Articleof wrist arthroscopy to resect synovial cysts [4]. Secondly, the procedure was performed by a robot-assisted installation of wrist arthroscopy to check the loss of synovial cysts Figure 1.A Free Hand® device (OR Productivity™, London, UK) has been connected to an arthroscopic 2D camera 2.4mm. An IR radiation emitting device was placed on the operator's head. An IR receiver was placed above the monitor to the arthroscopy column. Some movements of the operator's head were programming commands. The arm guided by IR sensor (top, bottom, right, left, and zoom) for example, to move the camera to the ulnar side, the surgeon should move his head towards right meanwhile his head is being tracked by an infra-red camera that translates this movement into a lighting arrow. Once the arrow turned on towards the desired direction, the surgeon validates the action with a foot pedal. The surgeon has to push the pedal again to activate the movement and hold it as long he wants to
AbstractThe purpose of this study was to test the use of an arm guided by an infrared sensor to move the endoscopic camera in wrist arthroscopy. Three synovial cysts resections were performed arthroscopically using the "hands-free camera" technique using the Free Hand® device (OR Productivity ™, London, UK). In 3 cases, the advantage was to free the 2 hands of the operator. Among the disadvantages, the time of surgery was longer, the operator had to make mental images rotations to orient the camera in space, and the steric bulk of the device caused friction with the instruments in the positions extremes. Overall, our results show that if the "hands-free camera" is not used in the state in wrist arthroscopy, its adaptation would have the advantage of freeing the two hands of the operator.
