Small incision and drilling technics using custom made skin protector

Incision shorter than the maximum width of the receiver-stimulator device (approximately 30mm) can be used, as
the skin and subcutaneous tissues stretch. We currently use a 25-30mm long incision. A spoon-like skin hook
(Li-Han instrument) is designed in order to position the receiver-stimulator device within the limitation of the
minimal incision (figure 1,2). The main purpose of using this skin hook is to give adequate release of soft tissue
and facilitate elevation of the scalp flap when drilling the well for the receiver-stimulator pedestal. Enlarging the
well safely to the required diameter and smooth-off the edges is feasible.
