Final answer:
During a cholecystectomy, blunt dissection of the gallbladder from the liver is likely performed using a Peanut dissector, an instrument for gentle tissue manipulation.
Step-by-step explanation:
The question pertains to a surgical procedure involving the gallbladder. Blunt dissection refers to a technique where tissues are separated or removed using instruments that are not sharp to minimize damage to other structures. The gallbladder is an accessory digestive organ that secretes bile into the duodenum to aid in fat digestion. During the surgical removal of the gallbladder, known as a cholecystectomy, blunt dissection of the gallbladder from the sulcus of the liver may be performed using a Peanut dissector, which is designed for gentle manipulation and separation of tissues.
