DEVICE: DORO LUNA® Retractor System (04250435519608)

A U-shaped surgical device intended to hold the head and neck in a particular fixed position during surgical procedures. It is connected to the skull with screws or pins (not included), typically on each side of the forehead, whilst the other end is fixed to an operating table or chair. Commonly known as a Mayfield skull clamp, it is made of metal materials (non-radiolucent) and may have adjustable joints (either incorporated or separate) for positioning/stabilization; it is not intended for applying traction forces to the cervical spine. This is a reusable device.

A distal component of a surgical retraction system, surgical retractor, and/or surgical instrument assist arm system designed to function as a parting edge to separate the margins of a wound/incision during a surgical procedure. It is intended to be attached to the frame (e.g., mounting ring/bar) of a surgical retraction system, or may be fixed onto a retractor handle; it does not include a handle. It is a metal device, sometimes referred to as a variable or vario retractor blade when assembled with a separate retractor handle, because it is available in a variety of lengths and sizes. This is a reusable device.

A frame-like assembly of surgical instruments/devices intended to be used to create a self-locking, self-retaining mechanism to temporarily part tissue (e.g., hold the edges of an incision open) to expose internal tissues or organs for access during open surgery; is not intended for neurosurgery or ophthalmic surgery. It includes a mounting frame (e.g., bar, ring) and a number of detachable retracting blades, may include additional features (e.g., ratchet mechanisms, fibreoptic lights), and might be intended to be mounted to the operating table or be non-fixed. It is typically made of high-grade stainless steel and synthetic materials. This is a reusable device.
