@Merc: Yes, we are placing it in the field. You are referring to recording as an outside party there to video, I am doing it as a surgical assist capturing what we do as we work. The reason for wanting the camera on the field is because we are doing small wrist/hand/finger surgeries that only occupy a few square inches. Then we have the doctor and myself seated on either side of the table looking over it, and the scrub on the end of the table blocking things from that direction too. On top of that, during about half of the case, an Xray machine is brought in over the table blocking any overhead view. Having the camera sterile allows me to have it beneath the xray machine obstruction, still viewing what we are doing.
For most of our cases we are using ceiling mounted cameras with pan-tilt-zoom controls and I have the remotes for them in a sterile bag. These work great unless we are blocking the view either with our bodies or the equipment.
As an aside, I have come up with a scheme to mount the gopro to a boom arm that can reach across from the non-sterile side of the patient, and get close enough to see what is going on without having to be sterile.
Cant wait to get my hands on the wifi bakpak so i can throw THAT in a sterile pouch and run it from the field. Throwaway bags are a lot cheaper, easier and faster to deal with than sterilizing camera housings.
