Final answer:
The retractor suitable for lifting the liver edge during surgical procedures is the Harrington Retractor, which is specifically designed to handle such tasks effectively without damaging tissues.
Step-by-step explanation:
The retractor used to lift the liver edge during a surgical procedure is a Harrington Retractor. Retractors are surgical instruments designed to hold back underlying organs and tissues, allowing surgeons access to body parts under incision. The Harrington Retractor is specifically designed with a deep, curved blade that is ideal for retracting the liver and preventing it from obscuring the surgical field. This type of retractor is widely used for abdominal and thoracic surgery due to its shape and the ability to provide substantial retraction without causing damage to the tissues.
