Innovation at MercyAscot 

VELYS™ Robotic-Assisted Solution

Our orthopaedic surgeons were among the first in the world to access the VELYS™ Robotic-Assisted Solution – a robotic surgical assistant for knee replacement surgery developed by DePuy Synthes, The Orthopaedics Company of Johnson & Johnson. 

A leading orthopaedic knee specialist who operates at MercyAscot, worked closely with DePuy Synthes on the development of the robotic-assisted solution, including using the technology for the first time in the world at Ascot Hospital in Greenlane.

The VELYS is an exciting new development for a number of reasons.

• It is a first-of-its-kind table-mounted solution, with an efficient design that integrates into any operating room.
• The system adapts to the surgeon’s workflow, is designed to give them the control they are used to, and helps them execute accurate bony cuts.²
• Every knee is different, and it allows the surgeon to individualise the total knee joint replacement to match the variable bony anatomy and soft tissue envelope of the patient’s knee. This patient-specific technique enables the surgeon to tailor the alignment of the knee replacement to the patient’s anatomy.
• It works exclusively with the ATTUNE Knee System, which studies have shown can improve clinical outcomes and patient-reported outcomes, as well as contribute to a shorter length of stay in hospital. ^{2, 3, 4, 5}

ROSA Robotic Surgical Assistant

The ROSA Robotic Surgical Assistant is robotic technology for total knee replacement developed by Zimmer Biomet that is efficient and accurate.^6,7

• The surgical procedure using the ROSA Knee is similar to traditional total knee replacement, but with a robotic assistant that personalises the surgical approach for the patient’s unique anatomy. 
• During the procedure, ROSA Knee utilises a camera and optical trackers attached to the leg to know exactly where the knee is in space. If the leg moves even a fraction of an inch, the robot can tell and adjusts accordingly. 
• Throughout the surgery, ROSA Knee provides the surgeon with data. This information, combined with the surgeon’s skill, helps them know how to position the implant based on the patient’s unique anatomy.
• Unlike traditional knee replacement methods, with ROSA Knee a series of x-rays may be used to create a three-dimensional (3D) model of the patient’s knee anatomy. This 3D model enables the surgeon to plan the specifics of the knee replacement prior to the surgery taking place. 
   

Da Vinci Xi Surgical System

The da Vinci Xi Surgical System is a robotic technology that continues to advance minimally invasive surgery across a range of specialities and procedures, including urology and gynaecology. 

• The da Vinci system allows surgeons to skilfully perform surgical procedures through tiny incisions. 
• Guided by magnified, high-definition images, the surgeon controls small robotic arms that can bend and rotate in ways the human hand cannot, providing greater dexterity, control, precision and vision. 
• The system is so precise that the instruments recheck their position by computer 1,500 times per second.
