The instrument used for bladder retraction during a cesarean section is C. De Lee.
During a cesarean section, various surgical instruments are used for different purposes. The De Lee retractor is specifically designed for bladder retraction to provide visibility and space for the surgeon to safely perform the procedure. It is important for the surgical team to use the correct instrument for bladder retraction to minimize the risk of injury to the organ.
Instruments such as Graves and Auvard are typically used as vaginal speculums, while the Heaney clamp is primarily used for gripping and clamping tissues, such as in hysterectomies. Understanding the function of each surgical instrument is crucial for efficient and safe surgical practice.
