 Perhaps the largest contribution to Islamic surgical development, came from Abū al-Qāsim Khalaf ibn al-‘Abbās al-Zahrāwī, Abū al-Qāsim, or Al-Zahrawi (936–1013).He contributed to advancements in surgery by inventing and developing over 200 medical instruments which constituted the first independent work on surgery.Such instruments included tools like forceps, pincers, scalpels, catheters, cauteries, lancets, and specula, which were accompanied by detailed drawings of each tool.
