Abstract: A handheld surgical instrument having a handpiece and a shaft extending from the handpiece is provided. The instrument includes a cutting implement disposed at a distal end of the shaft and an articulation portion disposed proximate to the cutting implement. The articulation portion includes a set of first slits and a set of second slits opposite the first set of slits. The articulation portion also has first and second passageways disposed in the slits along with first and second flat pull wires disposed in the passageways. The instrument also has an articulation control assembly that includes an articulator having first and second anchor points coupled with the first and second flat pull wires. The articulator moves the first flat pull wire in a first direction and moves the second flat pull wire in a second direction opposite the first direction during actuation.

Abstract: An elevator for an endoscope comprises a first end secured to the endoscope, a second end movable by an actuator, a flexible portion positioned between the first and second ends that is rotatable when the second end is moved by the actuator, and a guide portion extending between the flexible portion and the second end to receive an endotherapy instrument extending from the endoscope, the guide portion comprising a chute to guide the endotherapy instrument leaving the endoscope. A method of forming an elevator comprises forming from a planar sheet of material an elongate body comprising a length between first and second ends, a width, and a thickness, forming a guide body in the elongate body, bending the elongate body such that first and second lengths of the elongate body oppose each other to form an interior space, and bending the guide body to extend into the interior space.

Abstract: A rotatable surgical instrument and method includes an outer tubular member and an inner tubular member contained, at least in part, within the outer tubular member and configured to rotate relative to the outer tubular member, the inner tubular member and outer tubular member forming a gap therebetween. A distal tip is coupled to and configured to rotate with the inner tubular member. Bearings, each positioned in the gap and encircling the inner tubular member, are configured to maintain a separation between the outer tubular member and the inner tubular member. A spacer is positioned within the gap and between two of the bearings, wherein the spacer is configured to maintain a spacing between the bearings.
