Abstract: A surgical end effector includes a clevis and one or more jaws pivotally coupled to the clevis. At least one jaw includes a slot. An axle assembly includes a bearing axle that rotatably supports a bearing, which may be a plain bearing. An actuator coupling is coupled to the bearing axle. The bearing engages the slot such that pushing and pulling on the actuator coupling causes one jaw to close against the other jaw. The bearing axle and the jaws may be made from materials that are prone to galling and the bearing may be made from a material that resists galling. The slot may include a lip that supports the bearings in a spaced apart relationship. The bearing axle may be less than 1.5 millimeters in diameter and each bearing may be less than 3.0 millimeters in diameter.

Abstract: A cleaning device for a surgical instrument can include a body; at least one passage extending through the body from a first open end of the body to a second open end of the body. The first and second open ends and the at least one passage can be dimensioned to receive and guide a shaft of a surgical instrument during a cleaning procedure. At least one aperture in flow communication with a port and the at least one passage can define a cleaning fluid path from the port to the passage.

Abstract: An actuation element guide for a surgical instrument comprises a first piece, a second piece, at least one guide channel defining a twisted path about a longitudinal axis of the guide. The guide channel may be between the inner piece and the outer piece. A cross-section of the at least one guide channel, at a location along an axial length of the guide, may be defined by a surface portion of the first piece and by a surface portion of the second piece. Exemplary embodiments further regard medical devices including an actuation element guide and methods of manufacturing an actuation element guide.
