(google.de)
  • The invention of surgical forceps is attributed to Stephen Hales. (wikipedia.org)
  • invasive
  • The use of needles and needle systems in invasive procedures in various medical fields has become routine due, in part, to the ability of needles to pass through most tissues without causing significant destruction to the tissues. (google.com)
