摘要： A surgical device comprising: a handle assembly; a locking collar; and a set of replaceable bits that load along an axis into the handle assembly; wherein the locking collar is fully removable from the handle assembly, the locking collar loads axially to a first position, and the locking collar rotates between the first position and a second position; wherein, in the first position, the locking collar is free to be axially removed from the handle assembly and the replaceable bits are free to be loaded or unloaded from the handle assembly; wherein, in the second position, the locking collar is prevented from axial movement relative to the handle assembly and the replaceable bits are prevented from being received within, or removed from, the handle assembly; and the locking collar is guided to the first position and between the first position and the second position by a groove in the handle assembly mating with a member carried by the locking collar. And a surgical device comprising: a handle assembly comprising a rotatable drive shaft; a removable handle assembly adapter for connection to the handle assembly, the removable handle assembly adapter comprising a rotatable transmission shaft for connection to the rotatable drive shaft of the handle assembly; and a removable nosepiece assembly for connection to the removable handle assembly adapter and for selectively securing the shaft of a working element to the rotatable transmission shaft of the removable handle assembly adapter; wherein the removable handle assembly adapter and the removable nosepiece assembly each comprise a locking collar; and wherein the removable handle assembly adapter and the handle assembly each comprise a connector assembly, the connector assembly comprising: a housing comprising an opening; a collet sleeve disposed within the opening and connected to an input shaft, the collet sleeve comprising a lumen for receiving an output shaft; a locking element movable relative to the collet sleeve between (i) a locked position in which the output shaft is secured to the collet sleeve, and (ii) an unlocked position in which the output shaft is not secured to the collet sleeve; and a cam element movable relative to the collet sleeve between (i) a first position in which the locking element is free to assume its unlocked position, and (ii) a second position in which the cam element cams the locking element into the locked position; such that movement of the locking collar causes the cam element to move between the first position and the second position.

摘要： Collet chucks are described herein having design and architecture for minimizing and/or mitigating collet misalignment during rotary tool coupling operations. For example, a collet chuck comprises a housing for connection and rotation with a spindle about an axis of rotation, wherein the housing defines a socket for receiving a collet. The collet comprises a nose end engaging the socket and a second tapered end engaging a locknut assembly.

摘要： The chuck (10) is comprised of a chuck body (11) having an inner cone surface and a grip head (12) with a corresponding outer cone surface. The grip head (12) is subdivided into individual clamping jaws (21) by several seperating slots, said clamping jaws being connected to the grip head (12) by means of elastic connecting elements (22). Recesses (25) are provided on the inner cone surface of the chuck body (11) at least in the peripheral area of each seperating slot of the grip head (12), preferably also in the peripheral area of the apex line of each clamping jaw (21). Said recesses (25) have peripheral extension which is greater than that of the separating slots of the grip head (12) or the apex region of the clamping jaws (21). The axial extension of the recesses (25) is at least identical to the largest overlap area of both cone surfaces. The recesses (25) are filled with a filling body (27), made of an elastic, compressible material, up to the imaginary inner cone surface. The filling bodies (27) are permanently connected to the chuck body (11).

摘要： A chuck with a chuck body having a guide opening and an actuating element, and with at least one interchangeable clamp that can be inserted into the guide opening. The clamp has associated therewith a rotary disk with a blocking element that secures the rotary disk against rotation relative to the chuck body during insertion of the clamp into the guide opening. This makes it possible that, upon a rotation of the clamp about the longitudinal axis in the guide opening, a segment can be displaced outward toward the chuck body by the rotation relative to the rotary disk, via which the clamp is detachably secured on the chuck body. A clamp with a clamp body, a pivot body located in the clamp body, and a chucking element is also provided. The clamp has, at the opposite end of the clamping element, a locking unit that carries the pivot body.
