Connect the Obturator to the Obturator Handle
(Figure 3a) and insert into the Cannula, engaging
the flange on the Obturator into the Cannula slot
Lift the skin and subcutaneous tissue and insert
the Obturator and
Cannula into the cubital tunnel and advance it
proximally between
the ulnar nerve and the roof of the cubital tunnel
(Figure 3b).
Do not force the Cannula into the cubital tunnel.
Simultaneously, as the Cannula is placed in
the cubital tunnel, the
retractor is advanced superficial to the deep
fascia and deep to
the subcutaneous nerves/tissues
Remove the Obturator with Handle
Endoscopic Visualization
- Proximally
Insert the endoscope between the Cannula and
retractor (Figure 4a)
Use the endoscope to confirm that no superficial
nerves are in harms way (Figure 4b)
Insert the endoscope into the Cannula (Figure
4c)
Look through the series of slots at the inferior
surface of the Cannula to confirm that the ulnar
nerve is located directly beneath the Cannula
(Figure 4d). The Cannula may need to be rotated
slightly to capture the nerve beneath the flat
surface of the Cannula. Use the endoscope to visualize
the fascia stretched above the Cannula.
If the nerve is not clearly identified, pull
the endoscope back to the open portion of the
exposure and identify the nerve with a probe visually
through the open incision and then through the
endoscope
Trace the nerve proximally with the endoscope.
Make sure the nerve is under the Cannula throughout
the entire length of the Cannula.
