Microvascular vessel dilator
Spring-loaded, modified jeweler's-forceps instrument with elongated, smooth, non-tapering, highly polished tips, introduced into the vessel lumen to gently open and evert its cut edge; distinct from the already-catalogued microvascular clamp, which occludes/holds the vessel rather than stretching its edge.
How it is used
Held inside the artery/vein lumen during microvascular anastomosis while each suture is placed, to avoid suturing the back wall to the front wall ("back-walling").
