  • Patent number: 10898238
    Abstract: An instrument for spinal procedures is a vertebral endplate spreader device having a vertebral endplate spreader and a driver handle. The vertebral endplate spreader includes a linkage with a drive sprocket operatively connected for rotation relative thereto and with a secondary sprocket. The secondary sprocket is operatively connected for rotation relative to the linkage. The vertebral endplate spreader includes a belt operatively connected to the drive sprocket and the secondary sprocket to be driven about a belt axis. The driver handle has a distal end and a proximal end. The distal end is operatively connected to the drive sprocket to actuate rotation of the belt.

  • Patent number: 10595750
    Abstract: A device for orthopedic measurements includes a main housing, a center member, a measurement indicator, and a flexible member. The main housing has a proximal end with a top opening and a distal end with a side opening, and defines a longitudinal axis and includes a main housing cavity. The center member is disposed along the longitudinal axis within the main housing cavity. The measurement indicator is operatively connected to the center member, and is configured and adapted to display a measurement of a distance. The flexible member is threaded through the main housing cavity, and includes a first end and an opposed second end with an eyelet disposed proximate the side opening of the main housing. The eyelet is configured to be drawn away from the main housing, extending the flexible member outward with respect to the side opening to display a measurement on the measurement indicator.

  • Patent number: 8936599
    Abstract: An instrument includes a distraction mechanism having a proximal end and an opposed distal end. The distal end includes opposed first and second end members. A first vertebral endplate spreader includes a proximal spreader section mounted to the first end member of the distraction mechanism. The first spreader also includes a distal spreader section operatively connected to the proximal spreader section for lateral movement relative to the proximal spreader section. A second vertebral endplate spreader is mounted to the second end member of the distraction mechanism. The distraction mechanism is configured and adapted to distract the spreaders apart and to retract the spreaders together along a distraction axis. The distal spreader section of the first spreader is configured to move relative to the second spreader in a lateral direction relative to the distraction axis for correction of vertebral alignment, as in treatment of spondylolisthesis, scoliosis, and the like.

  • Patent number: 8656924
    Abstract: The subject devices and methods retain surgical instruments and sterile portions of any accompanying cables within sterile surgical fields. One such surgical device includes a surgical instrument for performing surgical procedures within a sterile field. A cable is attached to the surgical instrument for connecting the surgical instrument located within the sterile field to support equipment located outside the sterile field. A self-retracting coil is operatively connected to the surgical instrument. The self-retracting coil is adapted and configured to be anchored within the sterile field to ensure that the surgical instrument and the sterile portion of the cable remain within the sterile field during performance of the surgical procedure.
