An access port for use with a surgical system, the access port comprising:
- a cannula;
- an entry guide seal coupled to the cannula;
- an instrument entry guide comprising:
- a funnel portion including an upper part separately formed from and coupled to a lower part;
- a channel portion integral with the lower part of the funnel portion;
- first and second instrument channels;
- a single-piece seal body comprising a first instrument seal aligned with the first instrument channel and a second instrument seal aligned with the second instrument channel, wherein:
- the channel portion is removably received in the cannula through the entry guide seal;
- the entry guide seal is fixed in position relative to the cannula and seals against the channel portion as the channel portion is received in the cannula through the entry guide seal;
- the first and second instrument seals are arranged between the coupled upper and lower parts of the funnel portion;
- the single-piece seal body is arranged between the upper and lower parts of the instrument entry guide and comprises a pyramid portion;
- the pyramid portion comprises a first face and a second face;
- the first instrument seal comprises a first opening in the first face that aligns with the first instrument channel of the instrument entry guide;
- the second instrument seal comprises a second opening in the second face that aligns with the second instrument channel of the instrument entry guide;
- and
- the entry guide seal comprises a cross-slit seal comprising a curved concave distal end surface.
An access port for use with a surgical system, the access port comprising:
- a cannula;
- an entry guide seal coupled to the cannula;
- an instrument entry guide comprising first and second instrument channels, the instrument entry guide being removably received through the entry guide seal, the entry guide seal sealing against the instrument entry guide;
- a single-piece seal body comprising a first instrument seal aligned with the first instrument channel and a second instrument seal aligned with the second instrument channel;
- and
- a cap that couples the entry guide seal to the cannula, wherein:
- the cap comprises a clip;
- the instrument entry guide is coupled to the clip;
- the clip simultaneously inhibits translational movement of the instrument entry guide with respect to the clip and allows rotational movement of the instrument entry guide relative to the clip;
- single-piece seal body is arranged between the upper and lower parts of the instrument entry guide and comprises a pyramid portion;
- the pyramid portion comprises a first face and a second face;
- the first instrument seal comprises a first opening in the first face that aligns with the first instrument channel of the lower part of the instrument entry guide;
- the second instrument seal comprises a second opening in the second face that aligns with the second instrument channel of the lower part of the instrument entry guide;
- and
- the entry guide seal comprises a cross-slit seal comprising a curved concave distal end surface.
