Let's go ahead and review nuances for maximizing the microscope's potential via use of the mouth switch and a foot pedal. I'm also going to review the ergonomics necessary for making the surgeon comfortable and minimize fatigue. Here's a posterior fossa operation. You can see the surgeon is in the sitting position. I like the sitting position because it allows me to use the armrest, allows me to have my wrist dangle, or hang over the operative field. This upright posture, a very relaxed posture, minimizes fatigue, especially during the long operations. Importantly, the assistant is across the table from the surgeon, therefore transferring the instruments efficiently. I continue to use the mouth switch in order to keep the image in focus, and minimize the use of the microscope's handles to improve operator's efficiency. Here you can see the slight vertical movements to keep the image in focus. The pedals of the mouth switch are approximated continuously. Microscope surgery continues uninterrupted. If radical movements are necessary, the handles may be used, as you can see here. The upper pedal of the mouth switch is resting against the upper teeth of the surgeon and the lower jaw moves to approximate the pedals and relieve the brakes of the microscope. Here you can see the foot pedal is used to provide motion across multiple axes. Again, allowing the surgeon to continue microsurgery uninterrupted. For the standing position, similar principles apply. The mouth switch is used. You can see the pedals against the jaws of the surgeon. Their height is adjusted during the earlier part of the operation. So very relaxed posture. The mouth switch is used effortlessly making the microscope part of the face of the surgeon. Thank you.
