Surgical instruments islamThe final designs of all the surgical instruments used in the world today are attributed to al-Zehravi, one of the Andalusian Umayyads. Some 200 surgical instruments, including scalpels, bone saws and eye surgery scissors, are still used in modern medicine.

Zehravi also discovered that the stitches he made with thread made from animal intestines disappeared on their own and made the first capsule from animal intestines.

Al-Zehravi's major work is Kitab ul-Tasrif, a thirty-volume encyclopedia of medical practices. The surgical section of this work was later translated into Latin and gained popularity, becoming the standard textbook in Europe for the next five hundred years.
