Abstract

A surgical access port comprises a cannula comprising a proximal portion and a distal portion comprising a flexible section. The access port further comprises an instrument guide configured to be positioned within the cannula. The instrument guide comprises a proximal end, a distal end, and a plurality of instrument guide channels between the proximal and distal ends of the instrument guide. Each instrument guide channel of the plurality of instrument guide channels defines a corresponding guide channel opening. An outside surface of the instrument guide fits closely to an inner wall surface of the cannula when the instrument guide is within the cannula. A guide channel opening of a first instrument guide channel of the plurality of instrument guide channels is open to the outside surface of the instrument guide.

Dependent claims

A surgical access port comprising:

a cannula comprising:
a proximal portion;
and
a distal portion comprising a flexible section;
and
an instrument guide being removably insertable into the cannula, the instrument guide comprising:
a proximal end;
a distal end;
and
a plurality of instrument guide channels between the proximal and distal ends of the instrument guide, wherein each instrument guide channel of the plurality of instrument guide channels defines a corresponding guide channel opening, wherein the guide channel openings comprise proximal-facing openings, and wherein the proximal-facing openings are coplanar with one another,
wherein an outside surface of the instrument guide fits closely to an inner wall surface of the cannula when the instrument guide is within the cannula, and
wherein a guide channel opening of a first instrument guide channel of the plurality of instrument guide channels is open to the outside surface of the instrument guide from the proximal end of the instrument guide to the distal end of the instrument guide.

9 more elements

A surgical access port comprising:

a cannula comprising:
a proximal end;
a proximal portion;
and
a distal portion;
wherein a first diameter of the proximal end of the cannula is larger than a second diameter of the proximal portion of the cannula, wherein the second diameter of the proximal portion of the cannula is larger than a third diameter of the distal portion of the cannula, and wherein the second diameter of the proximal portion of the cannula is constant along a length of the proximal portion, and
wherein the cannula tapers from the first diameter of the proximal end to the second diameter of the proximal portion and tapers from the second diameter of the proximal portion to the third diameter of the distal portion, and
wherein the distal portion of the cannula is configured to be positioned within a patient anatomy;
and
an instrument guide configured to be positioned within the cannula, the instrument guide comprising:
a proximal portion configured to fit within the proximal portion of the cannula;
a distal portion configured to fit within the distal portion of the cannula;
and
a plurality of instrument guide channels, wherein each instrument guide channel of the plurality of instrument guide channels includes a proximal portion within the proximal portion of the instrument guide and a distal portion within the distal portion of the instrument guide, wherein the distal portion of each instrument guide channel defines a corresponding guide channel opening,
wherein an outside surface of the distal portion of the instrument guide fits closely to an inner wall surface of the distal portion of the cannula when the distal portion of the instrument guide is within the distal portion of the cannula, and
wherein a guide channel opening of a first instrument guide channel of the plurality of instrument guide channels is open to the outside surface of the distal portion of the instrument guide.
