摘要： Devices are described relating to the retaining of surgical tools within the chuck of a reciprocating surgical instrument, such as a reciprocating saw. A securing chuck is disclosed for securing a surgical tool to a reciprocating surgical instrument that comprises a shaft and a securing member. The shaft defines an axis and has a cylindrical bore extending along the axis. The bore is shaped to receive a substantially rounded tool shank. A pair of transverse slots extends into the shaft along a plane passing through the axis for receiving a substantially flattened tool shank. The transverse slots intersect with the cylindrical bore. The securing member is carried by the shaft and is radially movable relative to the bore both inwardly and outwardly to secure the surgical tool in the chuck.

摘要： A manual robotic tool changer provides a compact, lightweight means to manually selectively couple a robotic tool, such as a surgical tool, to a robot arm. The tool changer includes numerous safety features to prevent inadvertent decoupling of the robotic tool. These include a dual-button handle locking mechanism operative to lock the tool changer closed in the fully coupled position, and requiring simultaneous actuation of both of two latch buttons to unlock; a one-way clutch mechanism that prevents rotation of the coupling mechanism towards the decoupled position, unless the handle is actuated to unlock the tool changer; and a spring biasing the tool changer to an at least partially coupled state when no force is applied to the handle, thus requiring a positive force against the spring, moving the handle to a fully open position, to insert or remove a robotic tool.

摘要： In a robotic tool coupler, a rotating cam member having a plurality of surfaces formed therein urges a plurality of ball members in one tool coupling unit radially to contact an angled surface in the other tool coupling unit. Further rotation of the cam member exerts a radial force through the ball members onto the angled surface. A component of that force is directed by the angled surface toward the opposite tool coupling unit, locking the two units together. The cam member may include a failsafe surface and/or a failsafe lobe to maintain the two units locked together in the event of a loss of power to positively actuate the cam member.

摘要： The invention relates to a hand jig saw having a chucking device for a tool that can be moved back and forth, particularly a jig saw blade (15), the device having a centering piece (18) firmly connected to a drivable rod (13), the centering piece having an axial insertion slot (26) for a shank of the tool and at least one clamping body (19), which can be displaced in a transverse channel (27) extending transversely to the insertion slot (26) and immerses into the insertion slot (26), for clamping the shank (153). For displacement, the clamping body interacts with a chucking cam (28) configured on a chucking sleeve (20), which can be rotated relative to the centering piece (18), is disposed concentrically thereto and spring-loaded in the direction of rotation. In order to achieve a symmetrical chucking position of the tool in the chucking device and improved handling during replacement of the tool, two clamping bodies (19) arc disposed in two mutually aligned transverse channels (28) ending in the insertion slot (26) and displaceable in relation to each other, the chucking sleeve (20) is provided with two diametrically opposed chucking cams (28) arranged point-symmetrically relative to the axis of the chucking sleeve (20) for displacing the clamping bodies, and in the insertion slot (26) an axially displaceable spacer (22) that is spring-loaded in the extension direction of the jig saw blade (15) out of the centering piece (18) is held, on the longitudinal sides of which facing away from each other the clamping bodies (19) are non-positively applied by the chucking cams (28).
