  • Patent number: 9072947
    Abstract: Golf club heads are releasably engaged with shafts so that the club heads and shafts can be readily interchanged and/or so that the shaft position with respect to the club head can be readily changed. Golf clubs are provided that have spherical releasable connections between the golf club head and the golf club shaft along with head/shaft position adjusting features to allow interchange of shafts and heads and to allow modification of the head/shaft positioning properties. Assemblies for connecting the club head and shaft may include: a shaft adapter, a shaft retainer, and a hosel insert located within an interior chamber of the club head. The club head and shaft may be changed by releasing the securing system and exchanging the original parts with different parts. Furthermore, the shaft adapter may be rotated within the hosel insert to create different angles from the shaft so as to allow adjustment of the shaft position with respect to the club head.

  • Publication number: 20140214029
    Abstract: An apparatus comprises a body, a shaft, an end effector, and a firing beam. The shaft extends distally from the body. The end effector is positioned at the distal end of the shaft. The end effector comprises a first jaw and a second jaw, with the first jaw being pivotable toward the second jaw. The firing beam is operable to translate relative to the end effector to thereby drive the first jaw toward the second jaw. The firing beam includes a deformable portion operable to deform in response to a stress imposed by the end effector on the firing beam as the jaws clamp on dense or thick tissue. The deformable portion is defined in part by a cutout. A compliance restriction feature restricts deformation in the firing beam. A resilient member biases the firing beam to a non-deformed configuration.
