Single port access system
First Claim
1. A surgical access system comprising a trocar comprising:
- a fixation cannula comprising a tubular cannula body comprising a proximal end, a distal end, a longitudinal axis extending from the proximal end to the distal end; and
a cannula wall defining a cannula lumen;
a seal assembly coupled to the proximal end of the cannula body;
a retainer extending from the cannula body;
a locking component disposed on the cannula body and spaced from the retainer; and
a bolster engagable to the locking component, wherein the trocar has an insertion configuration in which the bolster is not engaged to the locking component, the trocar has a fixation configuration in which the bolster is engaged to the locking component, an artificial body wall, wherein the artificial body wall comprises a gel pad, wherein the gel pad is coupled to a cap ring, thereby defining a gel cap;
an adjustable wound retractor, wherein the adjustable wound retractor is couplable to the gel cap, and in the fixation configuration, the retainer and the bolster are dimensioned and configured to capture the artificial body wall therebetween, thereby fixing the cannula to the artificial body wall.

Abstract
Embodiments of a surgical access system useful for single or limited port procedures comprise a trocar comprising a fixation cannula, a retractor, and a gel cap removably coupled to the retractor. The gel cap comprises a gel pad that acts as an artificial body wall, through which instruments may be inserted into a body cavity, either directly or through one or more trocars. The fixation cannula comprises a retainer and a bolster, which together, capture the artificial body wall therebetween, thereby fixing the trocar thereto. The gel pad permits flexible instrument placement, as well as translational and angular degrees of freedom for the instruments while maintaining a gas tight seal.

17. A surgical access system comprising:
-
an adjustable wound retractor comprising; an proximal ring, distal ring, and a flexible, tubular retraction sheath extending between the proximal ring and the distal ring, wherein the proximal ring is rotatable around an annular axis thereof, thereby adjusting a length of the retraction sheath between the proximal ring and the distal ring; a gel cap comprising a cap ring and a gel pad coupled with the cap ring, wherein the cap ring is engagable with the proximal ring; and a trocar comprising; a fixation cannula comprising a tubular cannula body comprising a proximal end, a distal end, a longitudinal axis extending from the proximal end to the distal end; and
a cannula wall defining a cannula lumen;a seal assembly coupled to the proximal end of the cannula body; a retainer extending from the cannula body; a locking component disposed on the cannula body and spaced from the retainer; and a bolster engagable to the locking component, wherein the trocar has an insertion configuration in which the bolster is not engaged to the locking component, the trocar has a fixation configuration in which the bolster is engaged to the locking component, and in the fixation configuration, the retainer and the bolster are dimensioned and configured to capture the gel pad therebetween, thereby fixing the cannula to the gel pad. - View Dependent Claims (18, 19, 20, 21, 22, 23)
