A surgical instrument holder has a shank having a coupling end, a handle attached to an opposite end of the shank, a coupling device, and a locking mechanism. The coupling end has an interface thereon for receiving an instrument. The locking mechanism has an annular locking component, a spring, a ring which slides on the shank, and a locking device. The annular locking component is mounted so as to slide along the shank. The locking device cooperates with the locking component so as to lock the instrument onto the interface. The spring biases the locking component in a locking direction and bears on the ring. The ring is disengageably lockable to the shank via a connection device so as to enable quick disassembly for cleaning and component sterilization.

The surgical instrument holder of claim 2, wherein the surface corresponding to the surface of the surgical instrument is an inner surface of an annular piston, which piston slides within the recess and is biased toward the instrument by an elastic device, the piston contacting the instrument as the instrument enters the recess and is aligned with the inner surface, and wherein a locking element prevents the annular piston from exiting the recess, the locking element being a pin for engaging a bayonet slot on the instrument so as to enable locking of the instrument in an axially aligned configuration. 11. The surgical instrument holder of claim 1, wherein the coupling device comprises a coupling sleeve against which the spring is biased by the ring, the sleeve being slideable about the shank so as to operate a ball-detent mechanism wherein a ball is held so as to prevent the ball from being able to drop out of the mechanism when the holder is partially disassembled for cleaning. 12. The surgical instrument holder of claim 11, wherein a chamfered surface aligns the instrument axially, the chamfered the surface disposed on an annular piston which slides within the recess, the annular piston biased toward the instrument by an elastic device, wherein further, a locking element prevents the annular piston from exiting the recess, the piston contacting the instrument as the instrument enters the recess prior to and as the instrument is aligned with the ball-detent, so as to enable locking of the instrument in an axially aligned configuration. 13. The surgical instrument holder of claim 1, wherein a handle is attached to the first end of the shank. 14. The surgical instrument holder of claim 1, wherein the spring is a helical compression spring. 15. The surgical instrument holder of claim 1, wherein the locking direction is toward the coupling end of the shank. 16. The surgical instrument holder of claim 1, wherein the catch is a bayonet mechanism. 17. The surgical instrument holder of claim 16, wherein the bayonet mechanism is comprised of a bayonet slot and a locking pin. 18. The surgical instrument holder of claim 17, wherein the bayonet slot is disposed on the shank. 19. The surgical instrument holder of claim 1, wherein the interface is a recess intersected by a transverse slot wherein a wall of the slot engages a corresponding flat surface of the instrument. 20. The surgical instrument holder of claim 19, whercin the recess includes a seat shaped to receive the end of the instrument about its entire circumference. 21. The surgical instrument holder of claim 20, wherein a ball-detent enters an annular groove in the instrument along an axis perpendicular to the flat surface of the instrument. 22. The surgical instrument holder of claim 21, wherein the locking device slides over the ball detent to bias a ball into the recess in order to minimize play in the connection. 23.
