Laparoscopic instrument and related surgical method
First Claim
1. An instrument holder assembly for laparoscopic surgical operations,said instrument holder assembly having an insertion configuration for at least partial insertion of said instrument holder assembly through an incision at an operative site, andan in use configuration for use of said instrument holder assembly for access to said operative site, said instrument holder assembly comprising:
- a flexible member having a surrounding edge;
an at least partially flexible wall surrounding said flexible member, said at least partially flexible wall being connected to said flexible member all along said surrounding edge, said at least partially flexible wall having a longitudinal axis, said flexible member extending substantially transversely to said longitudinal axis, said at least partially flexible wall extending away from said flexible member at least in a direction away from the operative site; and
a plurality of cannulas connected to and extending from said flexible member inside said at least partially flexible wall, said plurality of cannulas defining a plurality of separate and mutually spaced apertures for receiving respective elongate laparoscopic surgical members, a first cannula of the plurality of cannulas being movable with respect to a second cannula of the plurality of cannulas;
wherein, for the insertion configuration, the flexible member and the at least partially flexible wall are folded into a compact configuration wherein the at least partially flexible wall has a compressible cross-sectional dimension, said compressible cross-sectional dimension along the longitudinal axis of said at least partially flexible wall being less than a dimension of the incision at the operative site where said at least partially flexible wall extends at least partially through the incision, andwherein during the in use configuration, the first cannula configured to receive a first curved instrument having a handle, a shaft and first and second jaws, the first and second jaws being rotatable relative to the shaft and the shaft being rotatable relative to the handle; and
the second cannula configured to receive a second curved instrument having a handle, a shaft and third and fourth jaws, the third and fourth jaws being rotatable relative to the shaft and the shaft being rotatable relative to the handle.
