Identify the following denoted instrument.

Appeared in: NORCET 2 - 2021 (shift-1)

Explanation

The instrument in the image is a Deaver retractor, identified by its distinct long, S-shaped or question-mark-like curve.
It features a wide, flat, and smooth blade designed for atraumatic retraction of large organs.
This type of handheld retractor is essential for providing exposure in deep abdominal and thoracic surgeries, such as retracting the liver or stomach.

Option B: A Doyen retractor has a blade that is perpendicular (at a right angle) to the handle, which is a different configuration than the gentle, continuous curve of the Deaver retractor.
Option C: Morris forceps are grasping instruments. While a Morris retractor exists, it is a heavy, right-angled instrument, unlike the one pictured.
Option D: Allis forceps are tissue-grasping instruments characterized by sharp, interlocking teeth at the tip, used for holding tissue firmly.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of Surgical Instruments as background academic context rather than a clinical decision trigger.
A nurse's familiarity with surgical instruments like the Deaver retractor is crucial for ensuring patient safety and operative efficiency. This includes anticipating the surgeon's needs, passing the correct instrument, and understanding its potential for causing tissue injury if used improperly.
During surgery, the scrub nurse must ensure that moist laparotomy pads are placed between the retractor blade and the organ to cushion the tissue and prevent pressure injury or ischemia from prolonged retraction.
What if? If the surgeon needed to retract a more superficial layer, like the skin and subcutaneous tissue for a smaller incision, a Deaver retractor would be too large and cumbersome. In that case, a smaller, shallower retractor like an Army-Navy or a Senn retractor would be more appropriate.

How to Approach the Question

First, carefully observe the key features of the instrument in the image. Note its overall shape, size, blade type, and handle.
The instrument is long, metallic, and has a continuous, gentle S-curve, ending in a wide, flat blade.
Consider the function suggested by its design. The smooth, broad, curved blade is designed to hold back large, soft structures without causing damage (retraction).
Evaluate the given options based on your knowledge of surgical instruments.
Compare the visual evidence with the characteristics of each option. A Deaver retractor matches the description of a deep, curved retractor. Doyen and Morris retractors are typically right-angled, and Allis forceps are toothed grasping tools.
Conclude that the instrument is a Deaver retractor based on the visual match.
