Seal port with adjustable height
View Patent ↗A surgical apparatus, for positioning within a tissue tract to access an underlying body cavity, is provided. The surgical apparatus includes a first and second member. The first member has a proximal ramp section, an accordion section, and a retaining portion. The first member defines a first longitudinal axis, a first proximal end, and a first distal end. The second member has a tubular proximal section, a portal portion, and a distal flange. The second member defines a second longitudinal axis, a second proximal end, and a second distal end. The second member includes a retaining structure to couple the first member to the second member. The first member is located at least partially in the tubular section of the second member.
1. A surgical apparatus for positioning within a tissue tract to access an underlying body cavity, the surgical apparatus comprising:
a first member defining a proximal ramp section, an accordion section, a retaining portion, and a longitudinal passage, the retaining portion located at a distal end of the first member; and
a second member defining a tubular section, a portal portion, and a distal flange, the second member having a plurality of ports defined by the portal portion;
the second member including a retaining structure located in a distal portion of the second member to couple the first member to the second member;
the first member being located at least partially in the tubular section of the second member, the longitudinal passage defined by the first member providing access to the plurality of ports defined by the portal portion of the second member, wherein the surgical apparatus is translatable between a first position where the second member has a first length and a second position where the second member has a second length different from the first length.
2. The surgical apparatus of claim 1 , wherein the first member has a proximal flange immediately adjacent to the proximal ramp section, the proximal ramp section being configured to increase an outer diameter of the first member from the accordion section to the proximal flange.
3. The surgical apparatus of claim 2 , wherein the surgical apparatus further includes a drawstring attached to the portal portion of the second member and to a post extending proximally from the proximal flange of the first member.
4. The surgical apparatus of claim 3 , wherein the drawstring is configured to translate the surgical apparatus between the first position and the second position.
5. The surgical apparatus of claim 1 , wherein the second member is deformable.
6. The surgical apparatus of claim 5 , wherein the second member is constructed of an elastic material.
7. The surgical apparatus of claim 5 , wherein the second member is constructed of a material selected from the group consisting of an open-cell polyurethane foam, a thermoplastic elastomer (TPE), a gel, and a polyisoprene material.
8. The surgical apparatus of claim 5 , wherein the second member defines a concave recess extending proximally into the second member.
9. The surgical apparatus of claim 1 , wherein the accordion section of the first member includes a plurality of convolutions configured to be folded onto each other to decrease a longitudinal length of the first member.
10. The surgical apparatus of claim 1 , wherein the retaining portion of the first member is a distal flange extending radially along the distal end of the first member.
11. The surgical apparatus of claim 1 , wherein the second member is molded with the first member.
12. The surgical apparatus of claim 1 , wherein at least one of the plurality of ports is adapted for the substantially sealed reception of a surgical object therein.
13. The surgical apparatus of claim 1 , wherein the accordion section of the first member is located at least partially in the tubular section of the second member.
14. The surgical apparatus of claim 1 , wherein translating the surgical apparatus from the first position to the second position causes the tubular proximal section to roll outward.
