Mechanism for managing and retaining a surgical drape
A cinch assembly affixed to a surgical drape may include at least two pairs of links connected by a hinge joint, with each link foldable relative to one another about the hinge joint between an unfolded configuration and a folded configuration. A portion of the surgical drape may be in an extended configuration when the pairs of links are in the unfolded configuration and may be in a gathered configuration when the pairs of links are in the folded configuration. The cinch assembly may further include at least two alignment and attachment element assemblies including first and second attachment elements configured to align with and engage with first and second complementary attachment elements of equipment of a surgical system.
1 . A sterile drape assembly for a surgical system, comprising:
a sterile drape; and
a cinch assembly affixed to the sterile drape, the cinch assembly comprising at least two of:
a hinged cinch assembly comprising a pair of links connected by a hinge joint, wherein:
the hinge joint is a scored region of material between the pair of links,
each link of the pair of links is foldable relative to one another about the hinge joint between an unfolded configuration and a folded configuration,
wherein a portion of the sterile drape is in an extended configuration in the unfolded configuration of the pair of links and is in a gathered configuration in the folded configuration of the pair of links, and
wherein, in the unfolded configuration, the pair of links define an elongate dimension and the scored region extends perpendicular to the elongate dimension;
an alignment and attachment assembly comprising a first attachment element and a second attachment element, wherein the first and second attachment elements are configured to align with and engage with respective first and second complementary attachment elements of equipment of a surgical system; or
an attachment assembly comprising another pair of links with a third attachment element mounted on one link of the another pair of links, wherein the third attachment element is configured to engage with a third complementary attachment element of equipment of a surgical system.
2 . The sterile drape assembly of claim 1 , wherein the attachment assembly further comprises a second cinch assembly affixed to the sterile drape, wherein the second cinch assembly comprises a plurality of links connected by an additional hinge joint.
3 . The sterile drape assembly of claim 2 , wherein the additional hinge joint comprises a living hinge.
4 . The sterile drape assembly of claim 1 , wherein the first and second attachment elements are configured to engage with the first and second complementary attachment elements of an active manipulator link of a manipulator system of a surgical system.
5 . The sterile drape assembly of claim 4 , wherein the third attachment element is configured to engage with a third complementary attachment assembly located at an opposite end of the active manipulator link from the first and second complementary attachment elements.
6 . The sterile drape assembly of claim 1 , wherein the hinged cinch assembly further comprises:
a first connector component mounted on a first link of the pair of links; and
a second connector component mounted on a second link of the pair of links,
wherein the first and second connector components are configured to mate together to be placed in a mated state, and
wherein in a state of the first and second connector components mated together, the pair of links is in the folded configuration.
7 . The sterile drape assembly of claim 6 , wherein the first and second connector components comprise a hook and loop fastening mechanism.
8 . The sterile drape assembly of claim 1 , wherein the hinged joint comprises a living hinge.
9 . The sterile drape assembly of claim 1 , wherein the first, second, and third attachment elements are configured to attach with the first, second, and third complementary attachment elements by magnetic force.
10 . The sterile drape assembly of claim 1 , wherein the hinged cinch assembly is configured to gather and cinch the portion of the sterile drape around an entry guide manipulator portion of a manipulator system of a surgical system.
11 . The sterile drape assembly of claim 1 ,
wherein the pair of links of the hinged cinch assembly is a first pair of links and wherein the portion of the sterile drape is a first portion of the drape,
wherein the hinged cinch assembly further comprises a second pair of links and at least one additional hinge joint connecting adjacent links of the second pair of links,
wherein the second pair of links are foldable relative to one another about the at least one additional hinge joint between an unfolded configuration and a folded configuration, and
wherein a second portion of the sterile drape is in an extended configuration in the unfolded configuration of the second pair of links and is in a gathered configuration in the folded configuration of the second pair of links.
12 . The sterile drape assembly of claim 1 , wherein the cinch assembly comprises each of the hinged cinch assembly, the alignment and attachment assembly, and the attachment assembly.
13 . The sterile drape assembly of claim 1 , wherein the cinch assembly is affixed to the sterile drape via pressure-sensitive adhesive.
14 . The sterile drape assembly of claim 1 , wherein the cinch assembly is made of high density polyethylene.
15 . The sterile drape assembly of claim 1 , wherein manipulation of the pair of links from the unfolded configuration to the folded configuration creates a fold in the sterile drape.
