ABSTRACT
Surgery relies on the scalpel; the surgeon's first instrument in every case. From early knives crafted in the pre-historic era to today, the scalpel has evolved along with medical and surgical fields but maintained its critical role and symbolism of operative intervention. A significant catalyst for change in surgical instrument development in the late 1800s was the evolution of anesthesia and antisepsis. Surgical instruments were affected by harsh sterilization techniques, creating need for a method to maintain surgical scalpel sharpness. Mathilde Schott, an early female biomedical engineering innovator, filed a patent (US431153) in 1890 for a detachable scalpel blade. Schott identified and responded to the needs of surgeons at the turn of the 20th century and created a detachable blade and stabilizing lever. Schott persevered in a society unaccustomed to women leaders, subsequently improving medicine, surgery, and engineering.
