Surgical port feature
A surgical port feature may include a funnel portion, a tongue, a waist portion, and surgical instrument channels. The waist portion may be located between the funnel portion and the tongue. The surgical instrument channels may extend from the funnel portion through the waist portion. The surgical port feature may further include a second tongue, with the wait portion being located between the funnel portion, the tongue, and the second tongue.
1. A surgical port feature for insertion into an incision site, the surgical port feature comprising:
a hollow funnel portion at a proximal end portion of the surgical port feature, wherein the hollow funnel portion comprises a wide opening at a first end of the hollow funnel portion and a narrow opening at an end opposite the first end;
a waist portion proximate the narrow opening of the funnel portion, wherein the waist portion has a central longitudinal axis and an outer surface radially spaced from and extending around the central longitudinal axis;
a first tongue member at a distal end portion of the surgical port feature, wherein the first tongue member extends distally from the waist portion in a direction away from the funnel portion, and wherein the first tongue member extends in a radial direction, relative to the central longitudinal axis, beyond the outer surface of the waist portion;
a second tongue member extending distally from the waist portion in a direction away from the funnel portion, wherein the second tongue member extends in a radial direction, relative to the central longitudinal axis, beyond the outer surface of the waist portion;
a rotatable portion positioned within the waist portion, wherein the rotatable portion is coupled to the second tongue member, and wherein the rotatable portion is rotatable about the central longitudinal axis relative to the funnel portion from a first orientation in which the first and second tongue members are positioned diametrically opposite one another across the central longitudinal axis to a second orientation in which the first and second tongue members are aligned at a same angular position about the central longitudinal axis; and
at least two channels extending through the waist portion and opening into the hollow funnel portion, wherein the channels are configured to receive surgical instruments.
2. The surgical port feature of claim 1 :
wherein the funnel portion has an oblique cone shape.
3. The surgical port feature of claim 2 :
wherein the oblique cone shape is one of an oblique circular or elliptical cone shape.
4. The surgical port feature of claim 1 :
wherein a first one of the channels comprises a socket positioned in the waist portion and configured to receive a ball joint.
5. The surgical port feature of claim 4 further comprising:
a ball joint positioned in the socket;
wherein the ball joint comprises an opening contiguous with the first one of the channels.
6. The surgical port feature of claim 1 , wherein the rotatable portion further comprises an indicator arranged to indicate a rotational position of the second tongue member.
7. The surgical port feature of claim 1 , wherein the channels extend through the rotatable portion.
8. The surgical port feature of claim 1 , wherein the first tongue member is longer than the second tongue member.
9. The surgical port feature of claim 1 , wherein, in a position of the surgical port feature inserted into an incision site, the incision is reoriented in response to moving an edge surrounding the wide opening of the funnel portion toward a plane of the incision.
10. The surgical port feature of claim 1 , wherein the funnel portion has a longitudinal axis that is angled relative to the central longitudinal axis of the waist portion.
11. The surgical port feature of claim 10 , wherein the tongue member is angled relative to the central longitudinal axis of the waist portion.
12. The surgical port feature of claim 1 , wherein the second tongue member extends in a different direction than the direction in which the first tongue member extends.
13. The surgical port feature of claim 1 , wherein the funnel portion and the first tongue member are integrally molded.
14. The surgical port feature of claim 1 , wherein the first tongue member comprises a material chosen from polyether ether ketone (PEEK), polyetherimide, polyethylene, and polypropylene.
