  • Patent number: 8784429
    Abstract: A distance indicator for indicating the distance that a device has traveled includes an elongate housing with a guidewire connector configured for operative connection to a guidewire to hold the housing stationary with respect thereto. A plunger is operatively connected to the housing for longitudinal motion with respect to the housing. A first plunger end is configured to operatively contact the device. As the guidewire connector is holding the housing stationary with respect to the guidewire, the first plunger end is placed into operative contact with the device with the plunger and housing in a first relative plunger/housing position. The device moves longitudinally. The plunger moves into a second relative plunger/housing position assisted by the operative connection between the first plunger end and the device. The longitudinal difference between the first and second relative plunger/housing positions indicates a distance that the device has moved longitudinally with respect to the guidewire.

  • Patent number: 8771285
    Abstract: A drive tool for accepting and rotationally locking the head portion of an orthopedic screw, such as a dental implant, to impart driving torque to the screw. In one exemplary embodiment, the drive tool includes an elongate body having an opening at its proximal end which is sized to receive the head portions of at least two different dental implants, the head portions of the dental implants being oriented at different angles with respect to the implant body portions. When the head portion of an implant is received within the opening, the drive tool is rotationally locked with respect to the implant. In this position, the body of the drive tool remains oriented so that same is substantially colinear with the body portion of the implant. Although the invention is described in the context of a drive tool used with a dental implant having a body portion and a head portion or abutment portion, the invention is more broadly applicable to drive tools which may be used with other types of orthopedic screws.

  • Patent number: 8764764
    Abstract: A plate puller device can include a head portion and extension rod portion. The device enables the fastener receiving member to be pulled against a bone surface before a head section of the fastener is advanced within the fastener receiving member into a locked position. The head portion can be positioned between the head section of the fastener and a surface of the fastener receiving member not adjacent to the bone surface. Also, a plate puller device can include a screwdriver, a grasper portion and a grasper sleeve. The grasper portion and grasper sleeve can be threadingly mated wherein rotation of the grasper sleeve forces a head portion of the grasper portion to grip the head section of the fastener to prevent the head section from advancing within the fastener receiving member.
