Sir William Arbuthnot Lane, Bt, CB, FRCS, Legion of Honour (4 July 1856 – 16 January 1943), was a British surgeon and physician. He mastered orthopaedic, abdominal, and ear, nose and throat surgery, while designing new surgical instruments toward maximal asepsis. He thus introduced the "no-touch technique", and some of his designed instruments remain in use.
