Abstract
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.
