Abstract: A guidance device for determining the angular orientation of the distal end of a surgical instrument, comprising an indicator portion containing a constant vertical reference attached to a securing portion for attaching to the surgical instrument shaft. The guidance device has graduated markings upon it for indicating angle of surgical instrument rotation from the vertical reference.

Abstract: A golf club swing training apparatus provides for several aspects of training in the game of golf with a single relatively simple device. The swing trainer is collapsible, and thus may be carried within a golf bag or the like for use by an individual golfer. The trainer may be unfolded, whereupon the two guides may be aligned with the intended ball trajectory and the guide connecting links adjusted to provide visual alignment cues to the desired trajectory. Adjustable positioning markers may be adjusted to provide assistance in the placement of the ball, the golfer's left and right foot, and the club swing arc, thus defining the proper placement and positioning for the club swing arc to properly strike the ball to drive it along the desired trajectory. A fence extends upward from each guide, so the swing trainer will be displaced if the club head is too far either side of the desired arc.
