A fine ivory and silver hydrocoele syringe with trocar and silver cannula by Maw Sons & Thompson dating to 1870.
The mechanism here is similar to a modern Venflon and this would be the antique equivalent. The trocar, sheathed in its silver cannula would be initially be inserted into hydrocoele (or other fluid filled cavity). With the trocar removed the syringe could be attached to the cannula to remove the bulk of fluid immediately. The cannula could then be left in place to allow continuing drainage. The set comes in a leather velvet and silk lined case.
