An instrument holder ( 10 ) for surgical use has a remote locking mechanism ( 12 ) and is elongated having a proximal end ( 14 ) and a distal end ( 16 ). The holder ( 10 ) has an elongated shank ( 20 ), a ring ( 22 ), a locking component ( 28 ) and a spring ( 32 ). The elongated shank ( 20 ) is equipped, at the distal end ( 16 ), with a head ( 26 ) adapted to receive an instrument ( 24 ). The locking component ( 28 ) is substantially cylindrical, elongated and is biased in a first direction ( 30 ) toward the head ( 26 ) by a spring ( 32 ). The locking component ( 28 ) includes structures ( 34 ) capable of locking the instrument ( 24 ) onto the distal end ( 16 ). The ring ( 22 ) is biased by the spring ( 32 ) in a second direction ( 36 ) against the locking component ( 28 ) towards the proximal end ( 14 ) constrained to slide longitudinally on the shank ( 20 ), at the proximal end. The remote locking mechanism ( 12 ) permits releasable connection to the shank ( 20 ) and is engaged by rotation of the ring ( 22 ) such that release of the ring from the shank allows the spring ( 32 ) and locking component ( 28 ) to slide freely off the shank in order to permit cleaning of the instrument holder.
