The Zeus System

ZEUS® Surgical System

The ZEUS® Surgical System is made up of an ergonomic surgeon control console and three table-mounted robotic arms, which perform surgical tasks and provide visualization during endoscopic surgery. Seated at an ergonomic console with an unobstructed view of the OR, the surgeon controls the right and left arms of ZEUS, which translate to real-time articulation of the surgical instruments. A third arm incorporates the AESOP® Endoscope Positioner technology, which provides the surgeon with magnified, rock-steady visualization of the internal operative field.

Peerless voice control capabilities allow the surgeon to precisely guide the movements of the endoscope with simple spoken commands, freeing the surgeon's hands to manipulate the robotic surgical instrument handles. ZEUS custom scales the movement of these handles and filters out hand tremor, enabling surgeons with greater capability to perform complex micro-surgical tasks.

In 1999, ZEUS made history in the world's first robotic-assisted beating-heart bypass surgery, by Douglas Boyd, MD.
The event ushered in a new era in Minimally Invasive Surgery, as promising and inspiring for patients as it is for surgeons and hospitals. Today ZEUS is being integrated into a broad range of procedures encompasing cardiac, bariatrics, general surgery, urology, and neurology.**

ZEUS® Surgical System—Features
  • The ZEUS® Surgical System features the following components:
    • Video Console
    • Primary Video Monitor up to 23"W x 23"D
    • Flat Panel Monitor: with support for an additional flat panel monitor
  • Surgeon Control Console
    • Touch Screen Monitor
    • Support Arms and Surgeon Handles
    • Mounting Areas: for speakers; access to controller front panels; access to PC and HERMES™ Control Center; mounting shelves for housing Control Units

Industry Standard Mechanism - Easy Sterilization

  • Incorporates mechanism design based on standard flushing port and push-pull rod technology, the same makeup as industry-standard endoscopic equipment. Provides easy sterilization.

Instrument Reusabilty

  • Uses robust, reusable instruments, built to withstand the rigorous OR environment.

Instrument and Port Size

  • Offers unparalleled precision through 3.5 to 5-mm instrument and endoscope accommodation.

Wide Array of Instruments

  • Offers a suite of more than 40 ZEUS®-compatible instruments, available in a variety of shaft diameters, from industry leaders Scanlan, Storz and US Surgical.

Quick Instrument Changes

  • Incorporates a quick-change mechanism to seamlessly swap instruments and safely guide the placement of the instrument tips.

Console Placement

  • Provides total flexibility in overall console placement, easily converting from setup directly at the operating table to setup as a physically removed console.

Rapid Setup

  • Takes less than 15 minutes to set up.

Visualation

  • Designed to adapt to individual surgeon preferences in viewing modes, permits both 2D and 3D visualization and accommodates a wide variety of endoscopes and monitor setups.

Secondary Monitors

  • Secondary flatscreen video monitors mount parallel to the main monitor to provide additional patient data including vitals, image guidance reference display and a redundant view of the operative field for use with SOCRATES™.

Profile

  • Built lightweight for easy installation and flexible adjustment, ZEUS® maintains a low profile. Its twin instrument positioning arms adhere equally to this design imperative, allowing assistant to retract, suction and irrigate during surgery.

Operation

  • A user-friendly, single foot pedal provides device engagement and disengagement. When engaged, specific controls are easily accessed using voice control and touch screen interfaces.

Microwrist Hand Controls

  • MicroWrist form-fitting hand controls translate the surgeon's movements with precise scaling and hand tremor filtering.

Six Degrees of Freedom

  • 4 Motorized
    • Up and Down
    • In and Out
    • Shoulder: Back and Forth
    • Elbow: back and forth
  • 2 Floating
    • Forearm: back and forth - safety function: float away to avoid ramming something
    • Wrist
  • 1 Fixed change in angle
    • Elbow Tilt (+/- 3 degrees)

Scaling

  • Offers infinite motion scaling, without limitation to arbitrarily defined increments. Scaling adjustment can be accomplished using either touchscreen or voice command.

Seating Accomodation

  • Ergonomic console and seat provides optimal surgeon comfort for long procedures

Repositioning

  • During surgery, endoscopic and instrument positioning arms tilt with the operating table; this flexible design eliminates the need to readjust or recalibrate the arms.

Re-Indexing

  • At any time, the foot pedal releases the clutch, allowing surgeons to relax and reposition (center and re-index) their hands and arms.

Endiscopic Position Saving

  • Provides the powerful capability to save 3 different endoscopic positions, retaining x-y-x axis coordinates that can be quickly and easily returned to at any time.

Voice Control

  • Voice control components leverage the advantages of a sophisticated overall communications paradigm: individual surgeon voice modeling; context sensitive tree command structure; limited vocabulary for error avoidance; voice and visual feedback on command success; compensation for ambient OR noise.

Pendant Control

  • Device control and communications options are embedded also in ZEUS®' portable pendant device, allowing flexible, duplicate control options that transcend the OR's sterile boundary.

Mirror Redundancy

  • Uses mirror redundancy technology at a rate of up to 1000 times per second to ensure patient safety.
