atraumatic grasper
Laparoscopic instrument designed to hold tissues without causing damage or perforation.
Full Definition
An atraumatic grasper is a specialized laparoscopic instrument designed with smooth, non-crushing jaw surfaces to grasp and manipulate delicate tissues without causing trauma, perforation, or tissue damage. These instruments typically feature broad, flattened jaws with fine serrations or specialized coatings rather than sharp teeth. They are essential for handling structures such as bowel, ovaries, fallopian tubes, and other organs where tissue integrity must be preserved. Common designs include Babcock graspers, DeBakey forceps, and various proprietary atraumatic designs. The term 'atraumatic' emphasizes the instrument's gentle action, though proper surgical technique is still required to prevent inadvertent injury.
Usage
Usage note: Hyphenated when used as a compound adjective (atraumatic-grasper design).
