The common term “tweezers” refers to a simple, spring-action tool used for grasping small objects, but in a medical setting, this instrument is known by a much more specific name: a forceps. The transition from the general, lay term to the professional medical vocabulary represents a necessity for precision in healthcare. Every instrument used in surgery or patient care has a detailed designation that describes its exact function, design, and intended use. This strict terminology ensures patient safety and procedural accuracy, as slight variations in an instrument’s tip or handle determine whether it safely manipulates delicate tissue or clamps a blood vessel.
Forceps: The Correct Medical Terminology
A forceps is defined as a hinged, handheld instrument used to grasp, hold, or manipulate objects, similar to pincers. In medical fields, the term describes tools that allow a practitioner to apply pressure or traction in areas too small or sensitive for fingers. These tools are engineered, often from high-grade carbon steel, to endure repeated sterilization required for surgical use.
Forceps fall into two main functional categories that determine their design. One category includes instruments designed for simple grasping and holding, similar to household tweezers, used to manipulate tissue or apply dressings. The second category involves clamping or locking instruments, frequently called hemostats. These instruments feature an integrated mechanism that allows them to maintain a continuous grip without requiring constant manual pressure. The instrument’s final name is determined by the combination of its handle style, locking mechanism, and the specific shape of its working tip.
Distinguishing Between Thumb and Ring-Handle Instruments
Forceps classification is based on the way the instrument is operated, separating them into two major design groups. Thumb forceps, often called “pick-ups” or “non-locking forceps,” resemble spring-tension tweezers. They are held between the thumb and index finger, requiring the practitioner to apply continuous pressure to maintain the grip. Examples include Adson and DeBakey forceps, used for delicate tasks like handling fine tissue, removing sutures, or manipulating surgical dressings.
Conversely, ring-handle forceps are hinged like scissors and feature finger rings and a locking mechanism called a ratchet. The ratchet consists of interlocking teeth that allow the jaws to be securely locked closed, providing a sustained, hands-free grip. This locking feature makes these instruments ideal for clamping blood vessels or securely holding tissue for an extended period. Locking forceps are often referred to as clamps and are favored for securing large structures or providing traction during a procedure.
Specific Designations Based on Function
The final, specific designation of a forceps depends entirely on the design of its jaw, which determines its intended surgical purpose.
Tissue Forceps
Tissue forceps are designed for handling internal, often delicate, biological structures and frequently feature teeth at the tip for a secure grip. For instance, Adson Tissue Forceps have fine teeth that intermesh to hold skin or fascia with minimal trauma. DeBakey Forceps have multiple fine, longitudinal serrations to provide an atraumatic grip, making them suitable for use on blood vessels or the gastrointestinal tract.
Dressing and Hemostatic Forceps
In contrast, Dressing forceps are designed for manipulating gauze, sponges, or other non-biological materials, and their tips are typically smooth or have blunt serrations. Using a toothed tissue forceps on a dressing could damage the material, emphasizing the need for specialization. Hemostatic forceps, such as Kelly or Crile forceps, are a subclass of ring-handle instruments designed for hemostasis (stopping bleeding). Their jaws feature transverse serrations that crush and occlude a blood vessel temporarily until it can be tied off with a suture.
Specialized Forceps
Another functional category includes Sponge Forceps, which have wide, often oval or circular tips to securely hold gauze sponges for swabbing the surgical field. Instruments designed for extraction or biopsy, such as Tischler Forceps, feature a specialized, often cup-shaped jaw to cleanly remove a sample of tissue for laboratory analysis.
