Surgical access port with ring actuated latching mechanism
View Patent ↗A surgical devices comprises a roll-up wound protector with a distal ring, a proximal ring, and a flexible sleeve having a length extending between the proximal and distal rings. The proximal ring has proximal, distal, medial, and lateral faces and is rollable to gather the flexible sleeve around the proximal ring and shorten the length of the flexible sleeve. A hand access port comprises a frame circumscribing an aperture. The aperture is aligned with the proximal and distal rings and is adapted to receive and seal against a surgeon's arm. A latching mechanism is connected to the frame and circumscribes the proximal ring, the latching mechanism having an engaged state wherein the hand access port is attached to the proximal ring and a disengaged state wherein the hand access port is not attached to the proximal ring. An actuation ring is operably connected to the latching mechanism to select between the engaged and disengaged states.
1. A surgical device, comprising:
a) a roll-up wound protector comprising a distal ring, a proximal ring, and a flexible sleeve having a length extending between the proximal and distal rings, the proximal ring having proximal, distal, medial, and lateral faces, the medial and lateral faces each comprising a circumferential recess, the proximal ring being rollable to gather the flexible sleeve around the proximal ring and shorten the length of the flexible sleeve;
b) a hand access port comprising a frame circumscribing an aperture, the aperture being aligned with the proximal and distal rings and being adapted to receive and seal against a surgeon's arm;
c) a latching mechanism connected to the frame and circumscribing the proximal ring, the latching mechanism having an engaged state wherein the latching mechanism engages the proximal ring at the circumferential recess in the lateral face to attach the frame to the proximal ring and a disengaged state wherein the latching mechanism disengages the proximal ring to detach the frame from the proximal ring; and
d) an actuation ring moveable relative the frame, the actuation ring being operably connected to the latching mechanism to select between the engaged and disengaged states.
2. The surgical device of claim 1 , wherein the actuation ring circumscribes the latching mechanism.
3. The surgical device of claim 1 , wherein the proximal ring has a figure eight cross sectional geometry.
4. The surgical device of claim 1 , wherein the proximal ring further comprises wire inserts.
5. The surgical device of claim 1 , wherein the hand access port comprises a flexible and compliant pad.
6. The surgical device of claim 5 , wherein the pad is a foam material.
7. The surgical device of claim 5 , wherein the pad is a gel material.
8. The surgical device of claim 1 , wherein the hand access port comprises an iris valve.
9. The surgical device of claim 1 , wherein the latching mechanism comprises a plurality of resiliently deflectable tabs attached to the frame.
10. The surgical device of claim 1 , wherein the actuation ring is axially actuated.
11. The surgical device of claim 1 , wherein the actuation ring is rotationally actuated.
12. The surgical device of claim 1 , wherein the actuation ring comprises cam surfaces.
13. The surgical device of claim 1 , wherein the latching mechanism comprises means for latching to the proximal ring.
14. A method of processing a device for surgery, comprising:
a) obtaining the surgical device of claim 1 ;
b) sterilizing the surgical device; and
c) storing the surgical device in a sterile container.
