Abstract
A cannula cap is disclosed. A cannula cap according to some embodiments of the invention includes an instrument guide attachment; a cannula attachment; and a seal captured between the instrument guide attachment and the cannula attachment. In some embodiments, a cannula cap can include a lid; a locking ring; a base; and a cannula seal captured between the lid and the base.
Claims19
A cannula seal assembly, comprising:
- an instrument guide having a proximal end and a distal end, the instrument guide including an annular flange and multiple instrument channels extending distally into the instrument guide, each channel being sized and shaped to guide a corresponding instrument into a cannula, and wherein the instrument guide is configured to rotate with respect to the cannula;
- an instrument guide attachment including a clip that contacts a proximal side of the annular flange on the instrument guide, wherein the instrument guide attachment prevents proximal movement of the instrument guide with respect to the instrument guide attachment and allows rotational movement of the instrument guide relative to the instrument guide attachment;
- a cannula attachment sized and shaped to removably engage with the cannula;
- and
- a seal captured between the instrument guide attachment and the cannula attachment, the seal including seal walls that seal against the instrument guide when the instrument guide is inserted through the seal, and that seal against each other when the instrument guide is not inserted through the seal.
2 more elements
A cannula seal assembly, comprising:
- an instrument guide including an annular flange, the instrument guide being configured to simultaneously receive a plurality of surgical instrument shafts into a proximal end of the instrument guide;
- a lid having a clip configured to contact the annular flange on the instrument guide to prevent proximal movement of the instrument guide with respect to the lid while allowing the instrument guide to rotate relative to the lid;
- a locking ring sized and shaped to releasably engage with a cannula, the instrument guide being configured to be received into the cannula when the instrument guide is coupled to the lid;
- a base coupled to the lid and the locking ring;
- and
- a cannula seal captured between the lid and the base, the cannula seal configured to seal against the instrument guide when the instrument guide is inserted through the cannula seal and configured to seal against itself when the instrument guide is not inserted through the cannula seal.
3 more elements
A surgical port kit, comprising:
- a cannula cap that removably engages with a cannula, the cannula cap including a cannula seal and a clip portion;
- and
- an instrument guide having a proximal end, a distal end, and a body extending between the proximal end and the distal end, the instrument guide including a plurality of channels, each channel being configured to receive an instrument shaft through a proximal opening, the instrument guide being sized and shaped for insertion through the cannula cap and the cannula seal, the instrument guide having an annular flange, and the clip portion of the cannula cap removably engaging the annular flange prevent proximal movement of the instrument guide with respect to the clip portion, wherein the instrument guide is rotatable with respect to the cannula when the clip portion of the cannula cap is engaged with the instrument guide.
