A neat hole made by a sharp instrument.
The making of a hole in an organ or swelling to take a sample of the contents or to remove fluid.
To pierce with a sharp instrument. N. wound made by a sharp instrument; it may be made accidentally as a result of trauma or deliberately as in a diagnostic procedure to withdraw fluid for examination.
A wound made accidentally or deliberately by a sharp object or instrument. Puncture wounds need careful treatment as a small entry hole in the skin can disguise serious injury in an underlying organ or tissue. Punctures are also performed for diagnostic purposes, in order to withdraw tissue or fluid for examination.
Description of a wound made by a sharp object, such as a knife, or by a surgical instrument. Puncture wounds are potentially dangerous. Despite an often small entry hole, serious damage may have been done to underlying tissues for example, heart, lungs, liver, or large blood vessel and surgical exploration may be required to assess the extent of the injury. Punctures through the skin are also done deliberately in medicine to extract fluid or tissue through a hollow needle so that it can be examined in the laboratory. Lumbar puncture, where cerebrospinal fluid is withdrawn, is one example.
A hole or wound made by a sharp pointed instrument.
A wound resulting from the deep penetration of the skin by a slender and pointed object.
