Davis herniotomy instrument
Used in hernia surgery
Instrument constructed from ebony and silver and is comprised of a cylinder hinged in two halves, a needle and a cover. After restoring the hernia the apparatus was inserted and the handle then removed, leaving the cover in place for 6-8 days to produce adhesions which would seal off the hernia. Which "By the most earnest advocates have been considered applicable to the to the smallest most recent and least troublesome hernias" their value being otherwise "denied or seriously questioned."
