1. A mechanism for securing expansible material to a carrier, comprising:
a recess in a wall of the carrier;
at least two opposing arms extending from the wall;
a bar connecting the at least two opposing arms, thereby creating a gap between the bar and the recess;
whereby expansible material is disposable in the gap and on non-recessed portions of the wall, such that the expansible material is securable at least in part by the bar.
2. The mechanism of claim 1, wherein the recess is not parallel to the wall.
3. The mechanism of claim 1, wherein the opposing arms extend from the recess in the wall.
4. The mechanism of claim 1, wherein the opposing arms extend from a region outside of the recess in the wall.
5. The mechanism of claim 1, wherein the securing mechanism further comprises:
a first edge of the wall having at least one beveled groove extending therethrough; and
whereby expansible material is extendable through at least a portion of at least one beveled groove.
6. A mechanism for securing expansible material to a carrier, comprising:
a first area of the carrier defined by at least one first rim;
at least one protuberance extending from the first area; and
a second area extending from the first area and being substantially perpendicular to the first area;
whereby expansible material is extendable through the first area and the second area, such that the expansible material is securable at least in part by at least one protuberance.
7. The mechanism of claim 6, wherein the second area is further defined by at least one second rim.
8. The mechanism of claim 6, wherein the expansible material is secured at least in part by a plurality of protuberances.
9. The mechanism of claim 6, wherein the protuberances are substantially cylindrical.
10. A mechanism for securing expansible material to a carrier, comprising:
a surface of the carrier having at least one wedged band thereon, the at least one wedged band having at least one angled side;
wherein expansible material is disposable on the surface and in contact with the surface and at least one angled side; and
wherein the expansible material is securable on the surface at least in part by at least one angled side.
11. The mechanism of claim 10, wherein the surface comprises at least one ledge substantially perpendicular to at least one wedged band and whereby expansible material is disposable on the surface and securable at least in part by at least one angled side and at least one ledge.
12. The mechanism of claim 10, wherein the surface comprises at least one recess area and wherein at least one wedged band protrudes from at least one recess area.
13. The mechanism of claim 10, wherein the surface of the carrier further comprises opposing sidewalls protruding from the surface such that expansible material spans the surface between the opposing sidewalls.
14. A mechanism for securing expansible material to a carrier, comprising:
a first area of the carrier defined by at least one first rim;
at least one protuberance extending from the first area;
a second area extending from the first area and being substantially perpendicular to the first area;
a recess in a wall of the carrier wherein at least a portion of the wall occupies the second area;
at least two opposing arms extending from the wall;
a bar connecting the at least two opposing arms, thereby creating a gap between the bar and the recess;
whereby expansible material is extendable through the first area and the second area and the gap, such that the expansible material is securable at least in part by at least one protuberance and the bar.
15. The mechanism of claim 14, wherein the securing mechanism further comprises:
a first edge of the wall having at least one beveled groove extending therethrough; and
whereby expansible material is extendable through at least a portion of at least one beveled groove.
16. The mechanism of claim 14, wherein the expansible material is reinforcement material.
17. The mechanism of claim 14, wherein the expansible material is baffle material.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A surgical access device comprising: a main frame having first and second members, each of said first member and said second member have a shape in the form of a U, the first and second members being angularly displaceable with respect to each other; a translation support translatably supported within the first member; a tilting support mounted within the second member; a first retractor blade securely mounted on the translation support, the first retractor blade defining a first concave interior portion; a second retractor blade pivotally coupled to the second member of the main frame, the second retractor blade defining a second concave interior portion, the first and second retractor blades assuming a first, approximated position and a second, spaced apart position, the first and second concave interior portions defining a channel therebetween in the first position, the channel configured and dimensioned to receive an elongate member; and first and second extension members slidably associated with the first and second retractor blades, respectively.
2. The surgical access device according to claim 1, wherein the first member includes a rotatable member rotatably associated with the translation support, whereby rotation of the rotatable member axially translates the translation support within the first member.
3. The surgical access device according to claim 2, wherein the second member includes a pinion rotatably associated with the tilting support, whereby rotation of the pinion pivotally moves the second retractor blade.
4. The surgical access device according to claim 1, wherein the main frame includes a locking screw to lock the angular displacement of the first and second members.
5. The surgical access device according to claim 1, further comprising an elongate member disposable in the channel.
6. The surgical access device according to claim 5, wherein the elongate member is an obturator.
7. The surgical access device according to claim 1, wherein the second retractor blade is connected to the tilting support of the second member.
8. The surgical access device of claim 7, wherein the tilting support of the second member is pivotable with respect to the second member.
