Abstract

See full text

A cylindrical shaft may be gripped with an apparatus including a housing having an axis and an inner surface with multiple asymmetric cam surfaces, a proximal end including a means to rotate the housing, and a distal end having an opening configured to receive the cylindrical shaft, at least two cylindrical gripping members configured to grip the cylindrical shaft, where each cylindrical gripping member contacts a corresponding asymmetric cam surface at a first rest position, and a rotatable frame which holds each pair of cylindrical gripping members at a fixed angular orientation relative to each other. The rotatable frame is configured to rotate upon insertion of the cylindrical shaft into a space defined by the gripping members so that each gripping member moves away from the axis of the housing along a first portion of the corresponding asymmetric cam surface. After insertion of the cylindrical shaft, the housing is configured to rotate so as to cause each gripping member to move toward the axis of the housing along the corresponding asymmetric cam surface.
