The operative introduction of a tube into the colon, usually the cecum, in the surgical management of intestinal obstruction or as a complementary procedure after resection often requires cumbersome manipulation. Incision into the bowel wall may lead to spillage before the tube is introduced, even when protected by rubber-shod clamps. The use of a trocar and cannula followed by threading of a catheter through the cannula or by direct insertion of the catheter after the cannula is removed entails awkward maneuvering and invites the hazard of gross contamination.
The device herein described was planned in order to permit the direct introduction of a tube into the colon with ease and safety. The same instrument is also suitable for intubation of any hollow viscus or body cavity (e.g., closed tube drainage of the thorax).
The instrument consists of a catheter containing a removable obturator with a sharp end (Fig. 1).
