The da Vinci robot is the most advanced platform for minimally invasive surgery currently on the market. This pride of robotic technology is available in two systems:
da Vinci Xi HD
Transcends the limitations of conventional surgery, enabling the surgeon to carry out complex operations in a minimally invasive manner, thanks to the integration of 3D, high definition vision, with the Endowrist instrument and an intuitive system of controlling the instruments.
It has three main components: the surgical console, the patient-side cart and the viewing trolley.
This is the control centre of the da Vinci Xi system. Via the console, located outside the sterile field, the surgeon manoeuvres the 3D endoscope and the EndoWrist instruments through two master controls and pedals.
In the stereo visor, the tips of the instruments are aligned with the surgeon’s hands, which grasp the master controls. The aim is to simulate the typical, natural alignment of the eyes, hands and instruments of open surgery, despite using a minimally invasive procedure. The scaling of the movements and damping of any tremor provide further control, minimising the impact of the physiological tremor or involuntary movements of the surgeon.
The person at the surgical console has the option of passing from a whole screen view to simultaneous multiple images (TilePro™ display), which show the 3D image of the operating field together with two other images (ultrasound, ECG..) delivered via axillary inputs.
This is the operative component of the da Vinci system and consists of four arms which hold the instruments and endoscope.
The da Vinci system uses remote-centred technology, a fixed point in space around which the arms of the patient-side cart move. This technology enables the system to manoeuvre the instruments and endoscopes within the site of surgery minimising the force exerted on the walls of the patient’s body.
In the posterior part of the cart, in correspondence with the handles for movements, the da Vinci Xi system has a touchpad and commands for pre-operative selection of the type of intervention, on the basis of which the arms are positioned automatically. It is also possible to position the arms manually, as far as concerns their height and advancement with respect to the base and rotation of the arm block, up to a maximum of 270°.
This contains the central processing unit and the image processing unit. It includes a 24 inch touchscreen display, an ERBE VIO dV electrosurgical generator for the delivery of monopolar and bipolar energy, and adjustable shelves for optional axillary surgical equipment, such as insufflators. The da Vinci Xi system also includes a full, high-definition video system.
The EndoWrist® instruments for da Vinci Xi have a diameter of 8 mm and are about 60 cm long. They have a ‘wrist’ that gives freedom of movement in seven axes and rotation of almost 360°. The range of robotic instruments includes needle holders, electrocautery forceps, cold forceps, grasping forceps and various types of bipolar dissectors.
