Surgical Hand Access Apparatus
View Patent ↗A hand access device includes a housing defining a longitudinal axis and having a passageway therethrough dimensioned to permit passage of a surgeon's arm and a fabric seal mounted within the opening and being dimensioned to form a substantial sealing relation with the surgeon's arm. The fabric seal is elongated extending along the longitudinal axis and may define a general hour glass configuration. A pair of flexible bands may be mounted about the fabric seal. The flexible bands are adapted to engage an outer surface of the seal to bias the fabric seal to a closed position thereof.
1. An assembly, which comprises:
a base retractor at least partially positionable within an opening in tissue and adapted to at least partially retract the tissue surrounding the opening, the base retractor defining a longitudinal axis and having a longitudinal channel extending along the longitudinal axis;
a hand access device mounted to the base retractor, the hand access device including a housing member having a passageway dimensioned to permit passage of a surgeon's arm or hand and a fabric seal disposed within the housing member, the fabric seal defining a seal opening adapted to form a substantial sealing relation with the surgeon's arm or hand; and
a pair of flexible bands mounted about the periphery of the fabric seal, the flexible bands normally biased to engage the fabric seal to substantially close the seal opening thereof, the flexible bands further adapted to move in a radial outward direction upon passage of the surgeon's arm or hand through the fabric seal.
2. The assembly according to claim 1 wherein the flexible bands are connected at respective end portions thereof and are adapted to bow outwardly upon passage of the surgeon's arm or hand.
3. The assembly according to claim 2 wherein the flexible bands include slots therein.
4. The assembly according to claim 1 , wherein the fabric seal generally defines an hourglass configuration.
5. The assembly according to claim 1 , wherein the flexible bands are connected to each other at respective end portions about respective pivot pins.
6. The assembly according to claim 1 , wherein the fabric seal comprises a lubricious coating.
7. The assembly according to claim 1 , wherein the fabric seal includes an elastomeric material formed with fabric material of the fabric seal.
8. The assembly according to claim 1 , wherein the fabric seal is coated with an elastomeric material.
9. The assembly according to claim 1 , wherein the housing member is mounted for rotational movement relative to the base retractor.
