Abstract
A device for accessing a cavity includes a tube and a trocar. The trocar extends through the tube and includes a handle, a sheath, and a tip member. The sheath is opposite the handle. The tip member is disposed in the sheath. The tip member is biased in an extension direction away from the handle. The tip member also includes an indicator indicating a position of the tip member relative to the handle.
Claims20
A device for accessing a cavity, the device comprising:
- a tube;
- a trocar extending through the tube, the trocar including
- a handle,
- a sheath opposite the handle, and
- a tip member disposed in the sheath and biased in an extension direction away from the handle, at least a portion of the tip member extending beyond the sheath in the extension direction throughout operation of the device, the tip member including an indicator indicating a position of the tip member relative to the handle.

A device for accessing a cavity, the device comprising:
- a tube;
- and
- a trocar extending through the tube, the trocar including
- a handle,
- a power source disposed in the handle,
- an indicator light source disposed in the handle, the indicator light source electrically coupled to the power source and configured to project light outside of the handle,
- a sheath opposite the handle, the sheath including an interior passage,
- a tip member disposed in the sheath and movable from an extended position to a retracted position, the tip member biased in an extension direction away from the handle toward the extended position, the tip member including a distal end opposite the handle extending beyond the sheath in the extension direction in both the extended position and the retracted position, the distal end of the tip member being wider than the interior passage of the sheath,
- a photoresistor disposed in the tip member nearer to the distal end of the tip member than to the handle, the photoresistor electrically coupled to the power source and to the indicator light,
- a utility light source disposed in the tip member between the handle and the photoresistor, the utility light source electrically coupled to the power source, and
- a light shield disposed between the photoresistor and the utility light source to direct light from the utility light source around the photoresistor and out the distal end of the tip member.
