Extractable filler for inserting medicine into animal tissue

摘要

An extractable device (10) is used to insert a medicinal filling into an animal tissue. The device comprises a filling member (20) and a pasty medicine. The filling member (20) is made of a flexible and hermetic wall (21) and is provided with a holding portion (22) and an injection port (23) via which the pasty medicine is injected into the holding portion (22) after the filling member (20) is inserted into the animal tissue. The holding portion (22) is provided with an opening (24) which is releasably lashed by one end of one or more threads (50,51) so as to make the opening leakproof. Upon completion of solidification of the pasty medicine in the holding portion (22) of the filling member (20), other end of the thread (50,51) is pulled to unlash the opening (24) of the holding portion (22), thereby enabling the filling member (20) to be extracted from the animal tissue so as to leave only the medicine in the animal tissue. <IMAGE>
