The Medtronic 90483 Biopsy Unit is a high-performance clinical instrument engineered for superior accuracy in diagnostic tissue acquisition. Developed by Medtronic, a global leader in medical innovation, the 90483 model is designed to streamline the biopsy process, ensuring that clinicians can obtain high-quality cellular and tissue samples with maximum efficiency.
This unit is a critical component in the diagnostic pathway, providing the reliability needed for laboratory analysis of complex pathologies. Its versatile design allows for integration into various clinical workflows, offering a standardized approach to tissue sampling across multiple organ systems.
Core Technology
The Medtronic 90483 utilizes advanced mechanical engineering to provide a controlled, high-velocity sampling action. This technology is focused on sample integrity, ensuring that the extracted tissue architecture remains preserved for histological examination. The unit is built with medical-grade, biocompatible materials that meet the stringent safety requirements of modern surgical and diagnostic suites.
Mechanism of Action
The 90483 Biopsy Unit operates through a specialized mechanical trigger system designed for precision. The mechanism follows a distinct procedural sequence:
-
Aspiration & Penetration: The unit supports both fine needle aspiration (FNA) for fluid/cytology and hollow needle techniques for core tissue samples.
-
Controlled Sampling: Upon activation, the device executes a rapid, precise stroke that captures a clean tissue specimen while minimizing trauma to the surrounding area.
-
Specimen Recovery: The design allows for the easy retrieval of the sample from the needle bed without compromising the cellular structure.
Clinical Applications and Uses
The Medtronic 90483 is a multi-organ diagnostic tool, highly effective for sampling both fluid and solid tissue from:
-
Pulmonary: Lung nodules and thoracic masses.
-
Hepatic: Liver parenchyma and focal lesions.
