A colposcopic surgical punch instrument includes a hoEow tube and a push rod extending through the hoEow tube. A handle is coupled to the proximal end of the tube and an actuation lever is pivotaEy coupled to the handle and the proximal end of the push rod for effecting axial movement of the push rod relative to the tube. A stationary jaw in the form of a die having an open top and bottom is coupled to the distal end of the tube and a movable jaw in the form of a punch is pivotaEy coupled to the stationary jaw by a tongue and groove arrangement In one embodiment, the stationary jaw is provided with a pair of ramped projections on its sides and a tab projection on its distal end. A removable plastic sleeve fits over the stationary jaw. The plastic sleeve has an open proximal end and an open top. A pair of holes in the sides of the sleeve engage the ramped projections on the sides of the stationary jaw and a hole in the distal end of the sleeve engages the distal tab on the stationary jaw. The top opening of the sleeve is dimensioned to aEow free movement of the movable jaw into and out of the stationary jaw. When attached to the stationary jaw, the sleeve functions as a multiple sample basket beneath the open bottom of the stationary jaw. In another embodiment the jaw has surface recesses and the sleeve has interior projections.
