  • Coupling assembly for variable diameter surgical instrument
    Patent number: 11602619
    Abstract: An apparatus may be used with an elongate member that includes an engagement member, a hollow shaft, a compression member, a compression element, and a resilient gripping member. The hollow shaft extends from the engagement member along a longitudinal axis. The compression member is slidably disposed over the hollow shaft. The hollow shaft is disposed over the resilient gripping member and supports the compression element. The compression member has a conical inner surface including a detent feature. The conical inner surface is configured to urge the compression element radially inwards as the collar advances from the unlocked position toward the locked position where the detent feature retains the compression element. The compression element deforms the resilient gripping member radially inwards to grip the elongate member and prevents translation of the elongate member. When unlocked, the resilient gripping member moves radially away from the elongate member allowing translation.

  • Adapter assembly to enable navigation for ENT instruments
    Patent number: 11484366
    Abstract: An apparatus includes a proximal portion and a distal portion attached to the proximal portion. The proximal portion includes a proximal surface. The proximal portion defines a first pathway and a second pathway that both extend distally from the proximal surface. The first pathway is dimensioned to receive a shaft while the second pathway is dimensioned to receive a navigation guidewire. The distal portion includes a distal tip terminating into a distal end. The second pathway extends from the proximal portion into the distal tip.
