Hand-held instrument holder for surgical use
First Claim
1. A surgical instrument holder comprising a shank having first driveable end and second coupling end, the second end a having an interface for receiving a surgical instrument, wherein the interface is a recess in the coupling end of the shank with the recess being coaxial with a central axis of the shank and having a polygonal cross section which rotationally aligns the surgical instrument, the coupling device held in functional assembly to the shank by a releasable locking mechanism comprised of a ring having a catch, the ring being slideably disposed about the shank, a spring biased in a locking direction against the coupling device by the ring, and the catch disengageably retaining the ring in a fixed position during use, wherein the ring locks over the shank, and whereupon release of the catch enables quick disassembly for cleaning and component sterilization, the catch being engaged in such a way that the release of the locking ring allows for partial disassembly for cleaning while retaining all the components of the holder together.

Abstract
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.

29. A surgical instrument holder providing a connection to a surgical instrument, comprising a shank, the shank having first driveable end and second coupling end, a T-bar handle attached to the first end of the shank, a coupling device, and a locking mechanism, wherein the coupling end has an internal recess therein for receiving an instrument, wherein the locking mechanism comprises an annular locking sleeve, a helical spring, a ring which slides on the shank, and a ball-detent mechanism wherein the ball is held so as to prevent the ball from being able to drop out of the mechanism and, the annular locking sleeve mounted so as to slide along the shank, the ball-detent being disposed in the coupling end of the shank and received into an annular recess in the instrument, the locking sleeve sliding over the ball detent to bias a ball into the recess to minimize play in the connection, wherein the spring biases the locking sleeve in a locking direction and bears on the ring, the ring being disengageably lockable to the coupling end of the shank via a bayonet mechanism comprised of a bayonet slot and a locking pin so as to enable quick disassmbly for cleaning and componet sterilization, wherein release of the ring allows for partial dissembly for cleaning while retaining all the componets of the holder together.

30. A surgical instrument holder comprising:
-
a shank having first driveable end and second coupling end; a “
T”
-handle disposed at the first driveable end;a coupling device disposed at the second end, the coupling device held in functional assembly to the shank by a releasable locking mechanism and having an interface for receiving a surgical instrument; and the releasable locking mechanism comprising a ring slideably disposed about the shank, a spring biased against the coupling device by the ring, and a bayonet mechanism comprised of a bayonet slot and a locking pin, the bayonet slot disposed on the shank, the bayonet mechanism retaining the ring in a fixed position during use, whereupon release of the bayonet mechanism enables quick disassembly of the ring, spring and coupling device for cleaning and component sterilization, wherein release of the ring allows for partial disassembly for cleaning while retaining all the components of the holder together.

31. A surgical instrument holder comprising a shank having first driveable end and second coupling end, the second end comprising a coupling device operating a ball-detent mechanism wherein the ball is held so as to prevent the ball from being able to drop out of the mechanism, and having an interface for receiving a surgical instrument, wherein the interface is a recess in the coupling end of the shank with the recess being coaxial with a central axis of the shank and having a polygonal cross section which rotationally aligns the surgical instrument and corresponds to a cross section of the surgical instrument, the corresponding cross section selected from the group consisting of a hexagonal cross section and a cylindrical cross section having a flat, and the coupling device held in functional assembly to the shank by a releasable locking mechanism comprised of a ring having a catch, the ring being slideably disposed about the shank, a spring biased in a locking direction against the coupling device by the ring, and the catch disengageably retaining the ring in a fixed position during use, wherein the ring locks over the shank, and the shank has a smaller diameter than the coupling end, and whereupon release of the catch enables quick disassembly for cleaning and component sterilization, the catch being engaged in such a way that the release of the locking ring allows for partial disassembly for cleaning while retaining all the components of the holder together.
