Abstract

Surgical access devices having wound closure features incorporated as part of the device are provided. The devices allow suture to be inserted directly into the device and operated to close an opening through which the device is disposed as or shortly after the device is removed from the surgical site. Further, the wound closure features allow for various orientations of wound closure to be achieved by adjusting an angle at which the suture enters tissue surrounding the opening to be closed. Some of the wound closure features provided for include openings formed in both the housing and cannula of the surgical access device, multiple openings formed in one or both the housing and cannula, locations of the openings being adjustable or otherwise movable, and various flexible seals. Other features, as well as methods of closing an opening through which the surgical access device was disposed, are also provided.

Claims27

Dependent claims

A surgical access device, comprising:

(a) a housing having a top surface, a central lumen extending therethrough, and a sidewall disposed around the central lumen, the sidewall defining a side surface of the housing, the housing having at least one opening extending transversely through the side surface, the at least one opening having an opening seal associated therewith;
(b) a cannula extending distally from the housing and in fluid communication with the central lumen to define a working channel that is sized and configured to receive a surgical instrument, the cannula having at least one sealed opening extending transversely through a sidewall thereof;
and
(c) a seal disposed within the working channel and configured to seal the working channel when no surgical instrument is disposed therethrough,
wherein the at least one opening of the housing is radially outward of the at least one sealed opening of the cannula,
wherein the at least one opening of the housing and the at least one sealed opening of the cannula communicate directly and transversely with the working channel, wherein the at least one opening of the housing defines a proximal-most transverse opening to the working channel,
wherein the at least one opening of the housing and the at least one sealed opening of the cannula are configured to form a suture path such that a suture can be passed from an outside environment, through the at least one opening of the housing, across the working channel, through the at least one sealed opening of the cannula, and to a surgical site.

A surgical access device, comprising:

(a) a housing having a top surface and a side surface;
(b) a cannula extending distally from the housing, the housing and the cannula defining a working channel extending therethrough that is sized and configured to receive a surgical instrument;
(c) a seal disposed within the working channel and configured to seal the working channel when no instrument is disposed therethrough;
(d) at least one entry port, wherein the at least one entry port opens to the working channel through the side surface of the housing;
and
(e) at least one exit port, wherein the at least one exit port opens to the working channel through a sidewall of the cannula,
wherein the side surface of the housing is positioned radially outward of the sidewall of the cannula such that the at least one entry port is positioned radially outward of the at least one exit port,
wherein the at least one entry port and the at least one exit port cooperate to define a suture path that extends across the working channel.
