Abstract

A medical device includes a wrist link. a tool member, and a tension element. The wrist link includes a discrete first link piece and a discrete second link piece. The first link piece includes a first clevis ear and the second link piece includes a second clevis car. The second link piece is coupled to the first link piece to position the second clevis ear opposite the first clevis car and to define a tension element guide channel between the first link piece and the second link piece. The tool member is coupled to rotate between the first clevis ear and the second clevis car about a tool member rotation axis. The tension element is coupled to the tool member and extends from the tool member through the tension element guide channel. Tension on the tension element urges the tool member to rotate about the tool member rotation axis.
