Cannula can be performed through a single access point,
and the extended length of a cannula allows for the selection of the safest incision area.
Also it can be bent around tissue structures and push away bloodvessels and nerve,
where a needle would simply pass through. Thus, cannula can reduce pain and shorten recovery time,
making the procedure more comfortable for the patient. Furthermore, blunt cannula helps to reduce
the risks of intravenous arterial embolism, enhancing patient safety.
