Medium-sized, right-angled handheld retractors, available in a range of sizes (can be single-bladed or double-bladed). These are commonly used to retract larger incisions in thoracic, abdominal and pelvic surgery. Sir Henry Morris was a British urologist who pioneered nephrolithotomy for renal calculi and was President of both the Royal College of Surgeons and the Royal Society of Medicine from 1910-1912. 21 Figure 10. Morris retractor 19 St Mark’s hospitalRetractors are used to hold incisions open and move structures such as skin, fascia and internal organs out of the way. They are essential surgical instruments, as they ensure optimal exposure of the operative field. This maximises the surgeon’s visibility and ability to safely reach deep structures, and provides a bigger workspace for dissection, suturing and knot tying. Retractors can be categorised into “handheld,” “self-retaining” and “table-mounted”. Handheld retractors Cat’s paw (a.k.a Volkmann/Senn-Mueller/rake retractor)
