Description

Watson Skin Graft Knife

Watson Skin Graft Knife with an overall Length 12″ (30.5 cm).
Modified Braithwaite design with a fine smooth rod which glides on the skin. It is a versatile and accurate hand held knife with an adjustable cut depth of 0.1mm to 1.0mm.
The roller bar is smooth and does not oscillate or rotate in use. The graft thickness is controlled by slackening the locking nut and rotating the adjuster nut until the required thickness and then set by tightening the locking nut. The graft thickness is consistent as the roller bar can only be adjusted in parallel.

The Watson Handle (1960 John Watson) addresses some of these issues as it has a fixed, polished, stainless steel guard and a simpler, more rigid thickness adjustment. The rod has no independent movement, either sliding or rotation, while the graft is being taken. At its end-bearings, it passes eccentrically through the bushes, hence the depth of cut can be set by rotation of the rod with the single knurled control knob, the rod remaining parallel to the blade settings. The bearings therefore have a precision fit and there is no “play” in use. While taking the graft, spontaneous rotation of the rod is slight, but the locking lever is provided to avoid accidental alteration of the setting once it has been made. The fixed guard reduces skin rolling however introduces a considerable degree of “drag” since it cannot slide to and fro with the skin surface. As a result the edges of both the graft and donor site can be ragged, an effect that can only partially be avoided by lubricating with liquid paraffin.
