Trocar with oblique needle insertion port and perpendicular seal latch
First Claim
1. A surgical access device, comprising:
- (a) a cannula having a proximal end, a distal end, and a cannula lumen extending therebetween through a medial portion of the cannula, wherein the proximal end includes a hub having a larger diameter than the distal end and the medial portion;
(b) a housing assembly coupled to the proximal end of the cannula, wherein the housing assembly comprises;
(i) a proximal housing, and(ii) a latch ring arranged distally of the proximal housing and having a user engagement feature, wherein the latch ring is rotatable by the user engagement feature to selectively couple and decouple the proximal housing with the latch ring and the cannula,wherein an interior of the housing assembly communicates with the cannula lumen to define a working channel extending from a proximal end of the surgical access device to a distal end of the surgical access device along a central axis thereof, wherein the working channel is configured to receive a surgical instrument therethrough;
(c) a first needle port that opens to the working channel through a first side of the hub of the cannula; and
(d) a second needle port that opens to the working channel through a second side of the hub of the cannula;
wherein each of the first and second needle ports is configured to direct a suture passer needle through the surgical access device, across the working channel, at an oblique angle relative to the central axis of the surgical access device,wherein the user engagement feature of the latch ring is circumferentially offset from each of the first and second needle ports.

Abstract
A surgical access device includes a cannula having proximal and distal ends and a cannula lumen. A housing assembly coupled to the proximal end includes a proximal housing and a latch ring having a user engagement feature. The latch ring is rotatable by the user engagement feature to selectively couple and decouple the proximal housing with the cannula. An interior of the housing assembly communicates with the cannula lumen to define a working channel extending along a central axis of the surgical access device. First and second needle ports open to the working channel through respective first and second side portions of the surgical access device. Each needle port is configured to direct a suture needle across the working channel at an oblique angle relative to the central device axis. The user engagement feature is circumferentially offset from each of the first and second needle ports.

15. A surgical access device, comprising:
-
(a) a cannula having a proximal end, a distal end, and a cannula lumen extending therebetween; (b) a housing assembly coupled to the proximal end of the cannula, wherein the housing assembly comprises; (i) a proximal housing, (ii) a distal housing secured to the cannula, and (iii) a latch member arranged distally of the proximal housing and having a user engagement feature, wherein the latch member is movable by the user engagement feature to selectively couple and decouple the proximal housing with the distal housing and the cannula, wherein an interior of the housing assembly communicates with the cannula lumen to define a working channel extending from a proximal end of the surgical access device to a distal end of the surgical access device along a central axis thereof, wherein the working channel is configured to receive a surgical instrument therethrough; (c) an insufflation port configured to direct insufflation fluid into the working channel; (d) a first needle port that opens to the working channel through a first side portion of the surgical access device; and (e) a second needle port that opens to the working channel through a second side portion of the surgical access device; wherein each of the first and second needle ports is configured to direct a suture passer needle through the surgical access device, across the working channel, at an oblique angle relative to the central axis of the surgical access device, wherein the latch member is movable to a position in which the user engagement feature is diametrically opposed from the insufflation port. - View Dependent Claims (16, 17)
