Ochsner trocar 22fr for 18fr catheter

A specialized surgical instrument designed to facilitate the insertion of an 18 French catheter through a controlled puncture. The 22 French Ochsner trocar features a sharp, pointed obturator housed within a cannula, allowing precise entry into body cavities such as the bladder or pleural space. The slightly larger size (22Fr) provides the necessary clearance for the 18Fr catheter to pass smoothly.
