A collection of devices intended to support and stabilize in a desired position a patient, or their body parts, on an operating table during a medical procedure (e.g., bariatric surgery, orthopaedic surgery, endotracheal tube intubation); some types may be intended to prevent patient sliding while in the Trendelenburg position or when applying traction. The set consists of multiple items which include two or more of the following: padded positioners dedicated to a body part such as arm, leg, shoulder, neck, or feet positioner, a headrest, a non-slip pad/bolster placed underneath the patient (e.g., cervical notch), and securing devices (e.g., straps). This is a single-use device.
