Medical Devices

Prosthesis is a noun referring to an artificial device that replaces a missing body part, such as a limb or tooth, to restore function. It also describes the field of prosthetics and the process of designing and fitting such devices. The term emphasizes engineered replacement rather than natural tissue restoration and is commonly used in medical, clinical, and orthopaedic contexts.

Thermometer (noun) is a device that measures temperature, typically consisting of a glass or digital tube with a calibrated scale. It enables readings of environmental or bodily heat. The term combines root elements referring to heat (thermo) and measure (meter).

Colposcope is a medical instrument used to examine the cervix, vagina, and vulva more closely under magnified, illuminated view. It helps identify abnormal tissue for diagnosis or treatment planning. The term combines roots for ‘hollow instrument’ and ‘to view,’ reflecting its purpose in gynecologic visualization.

Crutches are a pair of small, movable supports used to aid walking after injury or surgery, helping bear weight and maintain balance. They’re typically made of wood or metal with rubber tips and hand grips. The term also metaphorically describes something that tempers or reduces one’s own effort. Used in medical or everyday contexts, crutches are a practical mobility aid for temporary use.

Forceps are a pair of curved or straight surgical instruments used to grasp and extract objects, such as a baby’s head during delivery or foreign bodies. The term also denotes the instruments themselves. The word is of Latin origin and entered English in the medical lexicon, carrying a precise technical meaning rather than everyday use.

Laparoscope is a medical instrument, a slender, rigid or flexible tube with a camera and light at the end, used to view the abdominal cavity. The term refers to the apparatus and its use in laparoscopy, a minimally invasive surgical technique. It is pronounced with emphasis on the second syllable, yielding a precise, clinical /ləˈpær.əˌskoʊp/ in American usage, though variations exist in other English dialects.

Pacemaker refers to a medical device implanted to regulate the heart’s rhythm, or to a person or thing that sets the pace in various contexts. In healthcare, it typically denotes a small electronic device placed under the skin with leads guiding electrical impulses to the heart, maintaining a steady beat. The term can also be used metaphorically to describe something that drives routine or tempo in a system or process.

Sutures are fibrous joints where bones are held together by tough tissue, often allowing minimal movement. In biology, it also refers to the surgical stitching used to close wounds or incisions. The word appears in medical contexts (anatomy, surgery) and in dental or cranial discussions, typically as plural noun for bands or stitches and singular for a stitch itself.

Transducer is a device that converts one form of energy into another, typically turning electrical signals into sound or mechanical motion, or vice versa. In engineering contexts, it denotes components such as microphones, speakers, or sensors that transfer energy between domains. It is a technical term used across electronics, acoustics, and instrumentation.

Ultrasound refers to sound waves with frequencies higher than the upper audible limit of human hearing, typically used for medical imaging or industrial testing. The term combines 'ultra-' (beyond) with 'sound,' indicating waves beyond the normal range. In clinical contexts, ultrasound devices emit waves and interpret echoes to form images, while in non-destructive testing it reveals internal structures without invasive procedures.
