It is designed to facilitate complex surgery using minimally invasive approach.

The system is controlled by a surgeon from a console

Enables surgeons to perform delicate and complex operations through a few tiny incisions with increased vision,

precision, dexterity and control.

It consists of a surgeon’s console that is typically in the same room as the patient and a patient-side cart with four interactive robotic arms controlled from the console

Three of the arms are for tools that hold objects such as - Scalpel- Scissors- Bovie

The fourth arm is for anendoscopic camera with two lenses that gives the surgeon full stereoscopic vision from the console.

Surgeon Console The surgeon operates seated comfortably at a console while viewing a high definition, 3D image inside the patient’s body.The surgeon's fingers grasp the master controls below the display with hands and wrists naturally positioned relative to his or her eyes.The system also translates the surgeon's hand, wrist and finger movements into precise, real-time movements of surgical instruments.

The patient is positioned during the surgery; includes either 3 or 4 robotics arms that carry out the surgeon’s commands.

The robotic arms move around the fixed pivot points which reduces trauma to the patient, improves the cosmetic outcome and increases overall precision.

The system also does repeated safety checks, which prevent any independent movement of the instruments or robotic arms.

ProsSimpler procedureMinimally invasiveBetter techniqueReduced bleedingLess painfulSmaller scarFaster healingDecreased hospital stay

ConsLonger learning periodHigh cost of the equipment and thereby the procedureReduction in space for assistantsLack of tactile sensation for the surgeon

Better ways of accomplishing delicate medical procedures

Possibly for next generation medical robotics to conduct surgical prep work remotely

Removing human contact during surgery  Reducing or eliminating infection intra-

operatively Reduce the cost of maintenance Easy to operate
