A surgical instrument comprises a member configured for connection to an image guide defining an axis and being oriented relative to a sensor to communicate a signal representative of a position of the member. A stabilizer is aligned with the axis and configured to resist and/or prevent movement of the image guide from the orientation. Systems and methods are disclosed.

A medical device holding apparatus having a first arm with a holding portion to hold a medical device; a second arm connected to the rotatable first arm; a base connected to the rotatable second arm and having a support shaft standing in a vertical direction; and a first counterweight portion connected to the second arm, wherein the second arm has a fulcrum around which the second arm is rotatable, and the first counterweight has a slit being connected to the proximal end portion of the second arm for guiding the proximal end portion of the second arm when the second arm is rotated around the fulcrum; and a guide for moving the first counterweight in the vertical direction after the guide receives a force generated when the proximal end portion of the second arm is guided and moved in the slit.

A surgical microscope system includes a surgical microscope. When an additional unit is added to the microscope, the center of gravity of the microscope upwardly changes. In this case, an extension of a vertical-slider plate is joined with an upper joint location of a horizontal-slider plate, to raise a vertical slider together with a rotary shaft relative to the microscope, so that a weight balance of the microscope can be established only by sliding the vertical slider within its slidable range.

A stand apparatus for a surgical microscope includes a stand body and a parallel linkage. The parallel linkage is rotatably attached to the stand body by attaching a lower-end joint thereof instead of a vertical intermediate part thereof to the stand body. When the parallel linkage is tilted frontward, no part of the parallel linkage protrudes rearward. Weight balance of the frontward tilted parallel linkage is maintained by, instead of a counterweight, a compression spring arranged along a rear sub-arm.

Apparatuses and methods described herein relate to arm carts for transporting and securing a robotic arm to a surgical table. In some embodiments, an arm cart may include an arm support having two joints that can be manipulated to move an arm into a position in which a coupler of the arm is engageable with a coupling site of a surgical table. In some embodiments, an arm cart may include an arm support that is rotatable and translatable to permit movement of an attachment area for receiving and attaching a coupling site of a surgical table to a coupler attached to an arm. In some embodiments, an arm cart may include an arm support that releasably couples to a middle segment of the arm positioned at least two segments away from an end of the arm having a coupler for coupling to a coupling site of a surgical table.

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.

There is disclosed a mobile radiographic imaging apparatus including a component operable to emit radiation for imaging a subject, an arm rotatably connected at a proximal end thereof to a body section of the apparatus, such that it is supported by the body section and can slew relative to the body section about an upright axis, and to a distal end of which said component is connected, and a generator assembly arranged in the body section and including a generator arranged in the casing and electrically connected to said component, the apparatus being configured such that the generator assembly rotates with the arm, about said axis, wherein the generator assembly has a centre of mass which is radially offset from said axis in a second direction that is substantially opposite to said first direction.

Apparatus and systems herein support sharps containers and medical instruments trays, brackets, fasteners or holders on a mayo cart. Embodiments include an apparatus for attaching to a mayo cart to support a detachably mounted container, bracket or holder. A first portion has an arm extended to approximately the distance from the mayo cart vertical support pole to an outer edge of a mayo cart tray. A second portion attaches to the vertical pole proximate one end of the apparatus. A third portion attaches with the detachable container, bracket or holder proximate the opposite end of the apparatus. Embodiments may also include a detachable container, bracket or holder comprising an attachment portion to receive the third portion of the support apparatus for supportively attaching to the mayo cart. The support apparatus arm may also be extended to an adjustable length for attaching the container, bracket or holder with the mayo cart.

The invention relates to a medical apparatus having a medical optical appliance and a holding device with at least two holding arms which are connected movably to one another with at least one degree of freedom of movement via a joint and with an actuator which is connected to the two holding arms in such a way that a force can be exerted via the actuator between the two holding arms in the direction of the degree of freedom of movement. A control unit comprises a first regulator for outputting a first control signal to the actuator via an adjusting element. The medical optical appliance is mounted on the holding device.
