EDITORS COMMENTS
This 18th century print depicts the screw-type tourniquet designed by renowned French surgeon Jean Louis Petits. The intricately detailed copperplate engraving, created by Robert Benard for Denis Diderot's Encyclopedia published in Geneva in 1779, offers a fascinating glimpse into the medical practices of the time. At the heart of the device lies the tourniquet itself (1), which consists of a double band (2) designed to adjust the pressure applied to the limb. The bands are made of chamois leather (3), a material known for its ability to evenly distribute pressure and minimize damage to the underlying tissue. The tourniquet is secured in place by a ball bearing (4), which allows for easy application and removal. The use of a screw-type tourniquet marked a significant advancement in surgical procedures, enabling surgeons to effectively compress blood vessels during operations. By applying pressure to the affected area, the flow of blood could be temporarily halted, allowing the surgeon to perform intricate procedures with greater precision and control. This engraving not only showcases the ingenuity of Petits' design but also provides a captivating window into the world of 18th century anatomy and surgery. The intricate details of the device, from the double bands to the ball bearing, are beautifully rendered, offering a testament to the skill and artistry of the engraver, Robert Benard. This historical artifact remains an essential addition to any collection focused on the history of medicine or surgical instruments.
