A blade adapter couples a sagittal saw handpiece to an end effector of a robot to actuate a saw blade. The end effector has a first mechanical interface, and the sagittal saw handpiece has a second mechanical interface. The blade adapter includes a first coupling mechanism at a first side of the blade adapter and a second coupling mechanism at a second side of the blade adapter. The first coupling mechanism is coupleable to the first mechanical interface, and the second coupling mechanism is coupleable to the second mechanical interface.

Provided is a fixed point mechanism. In the fixed point mechanism, when a drive torque acts on a first connecting rod member (100) or a slide block device (110), the fixed point mechanism can realize a rotation movement around a fixed point; when a drive torque acts on a fourth connecting rod member (103) or a sixth connecting rod member (105), the fixed point mechanism can realize a telescopic movement relative to the fixed point; and when a drive torque acts on the first connecting rod member (100) or the slide block device (110), and another drive torque acts on the fourth connecting rod member (103) or the sixth connecting rod member (105), the fixed point mechanism can realize a rotation movement around the fixed point and a telescopic movement relative to the fixed point. That is, the fixed point mechanism has two degrees of freedom of the rotation movement around the fixed point and the telescopic movement relative to the fixed point.

Various embodiments concern locking release mechanisms that allow an articulated support arm to be moved between various vertical orientations. A locking release mechanism may include a handle release mechanism positioned within the handle of the articulated support arm, and a gas spring release mechanism positioned within the body of the articulated support arm. The articulated support arm can include a gas spring that remains locked until the handle release mechanism is activated, e.g. by applying pressure to a grip actuator. Other embodiments concern cable management techniques for articulated support arms. Oftentimes, an articulated support arm will include cables routed through the arm that are configured to support an attachment. For example, the cable(s) may be adapted for audio signals, video signals, power, etc. The cable(s) can be readily cleaned and/or serviced when routed through an articulated support arm composed of one or more removable pieces.

A memory device includes a first and second conductor respectively included in a first and second layer stack stacked in a first direction and separated from each other; a first and second portion of a semiconductor extending in the first direction between the first and the second layer stack, and separated from each other in same layer; a first film between the first conductor and the first portion; a second film between the second conductor and the second portion; a first insulator between the first conductor and the first film; a second insulator between the second conductor and the second film; a third insulator between the first insulator and the first film; and a fourth insulator between the second insulator and the second film. The third and fourth insulator have a higher dielectric constant than the first and second insulator.

A medical arm assembly according to an embodiment disclosed includes: a remote joint where a remote point is located; a positioning arm section configured to support the remote joint, move the remote joint that a position of the remote point relative to the reference point is changed only in the direction of a virtual reference straight-line through the reference point and the remote point, and fix the relative position of the remote point; an operating arm section connected to the remote joint and configured to fix a medical tool, rotate the tool about a remote rotation axis perpendicular to the reference straight-line and through the remote point, and move the tool in a direction perpendicular to the remote rotation axis and through the remote point; and an arm supporting section where the positioning arm section and the operating arm section are supported by connecting and the reference point is located.

A surgical end effector may comprise first and second jaw members. The second jaw member may comprise an offset proximal supply electrode that is positioned to contact an opposing member of the first jaw member when the first and second jaw members are in the closed position. The second jaw member may also comprise a distal supply electrode that is positioned distal of the offset proximal electrode and is aligned with a conductive surface of the first jaw member when the first and second jaw members are in the closed position. When the first and second jaw members are in the closed position, the proximal supply electrode may be in contact with the opposing member and the distal supply electrode is not in contact with the conductive surface of the first jaw member.
