Information about Scoop Trocar
Illustration from the Truax catalogue (1899), 208 fig. 382, which
notes that trocars originally consisted of triangular pointed
instruments used to puncture the wall of a cyst, organ or abscess,
for the purpose of evacuating any contained fluid. Generally such
trocars were constructed with an outer canula, the latter designed
to remain within the wound, thus supplying a channel for fluid
escape.... The Scoop Trocar...consists of a suitable shaft,
point, and canula, the latter terminating in a scoop or spout of
such form that it may be used to conduct the flow of liquid into
a basin or such receptacle."
