An articulating probe, comprises a first mechanism including a first link comprising a first longitudinal axis, a first articulation surface and a first motion-limiting element; and a second link comprising a second longitudinal axis, a second articulation surface and a second motion-limiting element. An articulation joint comprises the first articulation surface and the second articulation surface and constructed and arranged to allow two degree-of-freedom articulation of the second link relative to the first link. A motion resisting assembly comprises the first motion limiting element and the second motion limiting element, wherein the motion resisting assembly is constructed and arranged to resist rotation of the second link about the second longitudinal axis relative to the first longitudinal axis of the first link.

An instrument for applying fasteners such as bioabsorbable skull rivets, having a piston coaxially received within a housing. The piston has a tip at its distal end and the housing has a distal end sized to receive the tip and also to receive a portion of on of the fasteners. A slit in the housing allows it to flex and accommodate the fastener.

A self-centering bone drill comprises a drill bit having a proximal end and a distal end, a cutting surface at the distal end, and a first radially extending flange. A tubular housing coaxially receives the drill bit and a spring is coaxially received within the housing, and coaxially receives the drill bit. The spring is compressed between the first radially extending flange and an interior abutment surface on the housing distal of the first radially extending flange to urge the housing distally along the drill bit. A chamfered surface on a distal end of the housing engages a chamfered surface on a work piece to center the drill bit.
