This disclosure includes various embodiments of couplers for coupling intraosseous (IO) devices and drivers, and various embodiments of drivers and kits.

A hand-held power tool which includes a gear housing with a gear for transmitting a torque, generated by a drive motor, to a spindle. The gear housing is exchangeably connectable to a tool attachment via an interface in such a way that a torque is transmitted from the spindle to an input spindle of the tool attachment. The interface includes a housing-side interface element with a flange ring, which is connected to the gear housing in a torsionally stiff manner. The housing-side interface element corresponds to a tool attachment-side interface element which includes a fastening ring that is rotatably supported on the tool attachment. The fastening ring is brought into engagement with the flange ring by a coupled rotatory and axial relative movement of the fastening ring with respect to the flange ring so that the fastening ring and the flange ring together form a bayonet-type connector.

A surgical device comprising an adapter assembly is disclosed. The adapter assembly selectively interconnects a loading unit and a device housing, and includes at least one drive converter assembly for interconnecting a rotatable drive shaft and an axially translatable drive member of the loading unit. The at least one drive converter assembly converts and transmits a rotation of the rotatable drive shaft to an axial translation of the axially translatable drive member of the loading unit. The at least one drive converter assembly includes a drive element, a drive nut, and a distal drive member. The drive element defines a longitudinal axis. The drive nut is disposed about the longitudinal axis, and the distal drive member is disposed along the longitudinal axis.

An oscillating power tool includes a tool mount which can be articulated through a range of positions including less than zero degrees to ninety degrees. The tool mount can accept a variety of accessory tools which move in a reversing angular displacement as well as articulate throughout the range of positions. A locking mechanism is provided that can be manually actuated to prevent articulation or rotation of the articulator to thereby fix the tool mount to a pre-selected orientation.

A drill chuck having a chuck body that has a receptacle on its axially rearward end, having clamping jaws that can be moved relative to the chuck axis, and having a clamping sleeve that serves to move the clamping jaws. An adapter body can be placed in the receptacle and coupled in a torque-transmitting manner, which adapter body has an adapter receptacle for detachable connection to the drilling spindle of a power drill and has, in the wall of the adapter receptacle, at least one detent element that can be moved by a release sleeve.

A power tool adaptor for holding a tool adapted thereto including an adaptor body, a tool insertion cavity formed in an end of the adaptor body for receiving the tool, an elongated tool bit insertion cavity formed as a continuation of the tool insertion cavity, means for fixating the tool by protruding into one or more fixation recesses on the outer surface of the tool and means for attaching the power tool adaptor to a power tool; a reversible tool bit holder is further disclosed for holding two changeable tool bits, which reversible tool bit holder is adapted to fit into the power tool adaptor, along with a kit including a power tool adaptor and a reversible tool bit holder adapted to fit into the power tool adaptor.

A connecting device may have a tooth-shaped jacket, a locking body internally of the tooth-shaped jacket, a plurality of balls, a spring, and a spring base. The locking body has a rear end with an annular groove and has a neck with a plurality of spherical recesses containing the balls. Radial positioning between the locking body and the tooth-shaped jacket is realized through the balls. The spring is connected between the tooth-shaped jacket and the spring base and axial positioning between the spring base and the locking body is realized through a snap ring in the annular groove.

This disclosure includes various embodiments of couplers for coupling intraosseous (IO) devices and drivers, and various embodiments of drivers and kits.

A drill adapter apparatus for driving an input member which forms a loop includes a base, a first plate, and a second plate. The first and second plates are coupled to the base and are spaced from each other to accommodate a loop of an input member. Each of the first and second plates defines a hole which extends therethrough. A threaded fastener has a fastener shank sized such that the fastener shank is insertable through the holes of the first and second plates. The fastener shank is also sized and configured to insert through the loop of the input member. A nut is engageable with the threaded fastener to secure the threaded fastener to the first and second plates. A torque transfer member coupled to the base opposite the first and second plates which is shaped and configured to be rotatably driven by a drill.
