Identify the below Instrument?
Appeared in: AIIMS Delhi NO - 2018
Explanation
- The instrument shown is a core biopsy needle, specifically a Bard Max-Core model, which falls under the general category of a True Cut biopsy needle.
- It is designed to obtain a solid core of tissue for histological analysis, which is crucial for diagnosing diseases like cancer.
- Key features visible are the long needle, the spring-loaded handle (indicated by the buttons), and markings for brand (BARD) and size (22 mm), all characteristic of this device.
- This type of needle allows for a rapid, automated cutting action that provides a high-quality, intact tissue sample.
Why Other Options Were Wrong
- Option B: An infusion pump is an electronic device used to deliver fluids, nutrients, or medications into a patient's body in controlled amounts. It is a machine, not a handheld biopsy needle.
- Option C: An insulin pen is a reusable or disposable device used for injecting insulin for diabetes management. It has a very short, fine needle and a dial to set the dose.
- Option D: A USG (ultrasound) probe, or transducer, is a device that uses sound waves to create images of internal body structures. It is used on the surface of the skin and does not have a needle.

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.
- The nurse's role in a core biopsy procedure includes patient education, ensuring informed consent, preparing the sterile field, assisting the physician, and providing post-procedure care.
- Post-procedure monitoring is critical. The nurse must assess the biopsy site for bleeding, hematoma, and signs of infection. Vital signs are monitored to detect any internal hemorrhage, a rare but serious complication.
- Proper handling and labeling of the biopsy specimen are essential nursing responsibilities to ensure accurate diagnostic results.
How to Approach the Question
- This is an image-based identification question.
- First, carefully examine the instrument in the image. Note its overall shape, size, and key components.
- Identify any text or symbols on the instrument. In this case, 'BARD' and '22 mm' are visible clues.
- Analyze the functional parts: a long needle suggests a piercing or sampling function, and the handle with buttons suggests a mechanical or automated action.
- Synthesize these observations: a handheld device with a long needle and a firing mechanism is likely a biopsy tool.
- Evaluate the given options. 'True Cut biopsy needle or Core biopsy needle' accurately describes the instrument's appearance and function, while the other options describe visually and functionally distinct devices.
