A device for surgical assistance is disclosed. The device comprising one or more rails, and a plurality of side posts. The rails are configured to attach to a hand table via one or more engagement members. The plurality of the side post comprises an upper part and a lower part. The lower part of the said side post is engaged to the rails via a clamp mechanism. The upper part of the said side post is configured to hold surgical equipment. Further, each of the side post is height adjustable. The device further comprises a rail extension system, which is attached to an end portion of rails lying close to a trunk portion of the patient.

Systems and methods for ligament balancing during robotic surgery. One or more transducers are positioned within a knee joint to detect forces indicative of tension in ligaments and to provide output based on the detected forces. A distraction device is used to provide a distraction force to cause movement of a distal end portion of a femur relative to a proximal end portion of a tibia to increase tension in the ligaments. Information associated with output from the transducers is displayed for viewing.

A system for positioning and restraining a hand during hand surgery and similar may include a support plate and a plurality of finger restraining elements, wherein each of the finger restraining elements is removably connectable to a finger or a plurality of fingers, and is detachably attachable to the support plate. The support plate may include a magnetic material, and each of the finger re-straining elements may include a rigid ring portion for receiving a finger, and a fastening portion with a permanent magnet for detachably attaching the finger restraining element in a desired position on the support plate, so that a finger received in the ring portion can be secured to the support plate in the desired position.

A clamping system and method of clamping a rod includes a single knob coupled to a control screw. The single knob can increase or decrease a clamping force on the control screw. A clamp housing includes a control screw channel, wherein the control screw is disposed in the screw channel. A rod channel is capable of receiving a rod. A cleat channel extends into the rod channel. A cleat block has a clamping surface capable of entering at least a portion of the rod channel as the clamping force is increased on the cleat block.

Methods for preparing a bone in surgery using an imaging system, a navigation system having a locating device, and a robotic system having a cutting tool. A cannula is guided into an incision to expand the incision and provide access to the bone so that the cutting tool is insertable through the cannula to remove material from the bone. An implant is insertable through the cannula to be placed in the bone.

An apparatus for supporting an arm of a human patient during a medical procedure can include a base, an arm pad, and barriers for shielding scatter radiation. A medial portion of the base can lie between the human patient and a table on which the human patient is supported. The arm pad can be positioned on a lateral portion of the base. A first barrier can be mounted to the base and can be positioned laterally intermediate the medial and lateral portions, the first barrier extending upwardly from the base to above the arm pad. A second barrier can be mounted to the lateral portion of the base and extend downwardly. The arm pad can include a radiopaque panel that is horizontal.

Devices to secure the hand of a patient to a limb positioning device while evenly distributing the applied traction load across the patient's hand and wrist are disclosed. The hand is placed in the open position into a soft mitten, while an anatomically-shaped plate is attached to the mitten for supporting the palm of the hand in the open position. Straps are then secured around the patient's wrist and hand. Finally, the entire device is overwrapped an elastic bandage and secured to the limb positioning device. When traction is applied, the shape of the plate, the construction of the mitten, and the straps combine to allow low-contact pressure across the patient's hand and wrist.
