Abstract

The present invention relates to surgical access devices (or surgical access ports) and related methods. More particularly, the present invention relates to such devices that are advantageously adapted for use in single-incision laparoscopic surgical (“SILS”) procedures The present invention also relates to kits and methods involving such surgical access devices.

Claims

1. A method of performing a laparoscopic surgical procedure through a single incision, comprising the steps of:

a) creating a single incision through the abdominal wall of a patient to gain access to the patient'"'"'s abdominal cavity;

b) providing an insertion device having a handle assembly with pivotable latching arms moveable between open and closed positions and an elongated trocar shaft;

c) providing a plurality of access ports each having a housing and an elongated body, wherein the housing of each access port includes a flange and the elongated body of each access port includes a telescopic tube assembly surrounded by an elastomeric sheath, wherein the tube assembly includes an outer tube fixed to the housing and an inner tube fixed to the sheath;

d) sequentially mounting each access port to the insertion device by;

i) extending the trocar shaft into the elongated body to elongate the telescopic tube assembly and thereby stretch and reduce the profile of the elastomeric sheath; and

ii) engaging the flange of the housing with the pivotable latching arms of the handle assembly to releasably secure the elastomeric sheath in a stretched condition;

e) sequentially inserting the elongated body of each access port through the incision and into the abdominal cavity of the patient, while the elastomeric sheath is in the stretched condition; and

f) sequentially disengaging the housing of each access port from the handle assembly to allow the elastomeric sheath to return to an unstretched condition within the incision.

2. A method according to claim 1, further comprising the step of arranging the plurality of access ports adjacent to one another in a nested configuration within the incision so that the housing of at least one access port nests above and overlaps the housings of the other access ports.

3. A method according to claim 2, wherein the step of arranging the plurality of access ports adjacent to one another in a nested configuration involves arranging three access ports in such a manner so that the housing of a center access port nests above and overlaps the housings of two outer access ports.

4. A method according to claim 2, wherein the step of arranging the plurality of access ports adjacent to one another in a nested configuration involves arranging three access ports in such a manner so that the housings of two outer access ports nest above and overlap the housing of a center access port.

5. A method according to claim 2, wherein the step of arranging the plurality of access ports adjacent to one another in a nested configuration involves arranging three access ports in such a manner so that the housing of an outer access port nests above and overlaps the housing of a center access port, while the housing of another outer access port remains even with the housing of the center access port.

6. A method according to claim 2, wherein the step of arranging the plurality of access ports adjacent to one another in a nested configuration involves arranging four access ports in such a manner so that the housings of two of the access ports nest above and overlap the housings of the other two access ports.
