    Abstract: A wound retractor includes a sleeve with proximal and distal ends, an inner ring inside the sleeve between the proximal and distal ends, and an outer ring outside the sleeve between the proximal and distal ends. The inner ring includes a tapered outer surface that increases in diameter from a proximal end of the inner ring toward a distal end of the inner ring. The outer ring includes a tapered inner surface that increases in diameter from a proximal end of the outer ring toward a distal end of the outer ring. A portion of the sleeve is captured between the tapered outer surface and the tapered inner surface.

    Abstract: Disclosed are medical devices for surgical procedures, especially procedures that involve the manipulation of surgical instrument end effectors close to the skin surface at an incision site. In accordance with some embodiments, an instrument access device is configured to couple to a wound retractor at a distal end of the device and to receive a multiple instrument entry guide in a port at the proximal end of the instrument access device, with an envelope between the distal and proximal ends defining a sealed cavity for maintaining insufflation pressure. Various embodiments provide means for rotating an assistant port in the envelope about a port that receives the instrument entry guide without twisting the envelope. Also disclosed are various envelope shapes. Also disclosed is an instrument entry guide that aligns surgical instrument shafts.

    Abstract: A sheath for a surgical instrument may include a sleeve having a distal end and proximal end, and a retention mechanism at a proximal end portion of the sleeve. The retention mechanism may comprise a sleeve attachment portion configured to be attached to the sleeve at the proximal end portion, and a locking collar extending from the sleeve attachment portion, wherein the locking collar is configured to receive a connector portion of a surgical instrument. The locking collar further may include a locking feature movable between a first configuration, in which the sheath is moveable relative to the surgical instrument, and a second configuration, in which the locking feature is configured to engage with the connector portion to retain the sheath in position on the surgical instrument.
