Final answer:
The suitable needle for liver repair is the blunt needle, used to minimize damage to the friable liver tissue during surgical procedures.
Step-by-step explanation:
When performing surgical procedures on the liver, surgeons prefer to use blunt needles because the liver tissue is friable and easily damaged. Blunt needles reduce the risk of causing unintended punctures or lacerations which can lead to excessive bleeding.
Unlike sharp needles, which are ideal for cutting through tough, fibrous tissue, blunt needles gently push the parenchymal cells aside. This action minimizes trauma and aids in the healing process. It's important to use the correct needle to prevent complications and promote efficient surgical repair.
