In-hospital and remote surgery

During the projected period 2021-2031, the worldwide surgical robotics market is expected to rise at a robust CAGR of 10.2%. In terms of revenue, the surgical robots market generated $5.46 billion in 2020 and is expected to reach $16.77 billion by 2031.

Despite the inherent risks associated with human error and mechanical issues, robotic surgery represents a paradigm shift in minimally invasive surgery, one which has resulted in increased competitiveness. AngioDynamics, Titan Medical, CMR Surgical, Johnson & Johnson, Auris Health, and Medtronic, to mention a few, are competing with investors’ favorite Vicarious Surgical.

The Vicarious Surgical robot-assisted surgery technology is intended to imitate the surgeon’s upper-body joints, allowing them full access to the abdominal cavity with only a 1.5-cm incision.The camera moves in sync with the surgeon’s head movements, creating a totally immersive experience.

The company offers technological advantages over conventional robotic platforms that to date have worked to improve the comfort of procedures for both patients and doctors.

Remote consultations and patient care

The immersion factor of AR/VR technologies has opened the door to encompass new treatment strategies. XRHealth was the first company to develop virtual reality clinics that give remote care to patients across the United States, and it is covered by most major health insurance companies including Medicare. Virtual support groups, where patients with comparable diseases can connect anonymously and remotely with expert physicians monitoring the group, represent one of the distinctive elements of VR therapy.

Karuna Labs is using evidence-based approaches to treat chronic pain through virtual reality simulations. The solutions offer patients at-home and local clinic programs that address chronic pain and help to “unlearn” it. Using a combination of physical and cognitive retraining, the brain is ‘re-taught’ to see painful movements from a different perspective, sparing the body from feeling any further pain.

As part of a pilot study, patients undergoing surgery at St George’s Hospital in London had the option of wearing a virtual reality headset prior to and during their procedure which would allow them to enjoy relaxing landscapes. The feedback was overwhelmingly positive. Wearing the headset improved the overall hospital experience for 100% of the participants, and 94% indicated it made them feel more relaxed. Furthermore, 80% stated they experienced less discomfort and 73% indicated they felt less worried after putting on the headset.

Improved diagnosis and treatment

Visual-driven technology such as X-rays and CT scans are common in the healthcare industry; they assist medical practitioners in detecting, diagnosing and treating patients by allowing them to look deep within their patients’ bodies.

Augmented reality is building on these established technologies to create accurate and realistic 3D images that can be accessed and scrutinized by practitioners via augmented reality hardware.

These days, nurses and doctors can use augmented reality to improve vein detection. AR-driven technologies such as Accuvein use a portable, handheld device that houses a laser-based scanner, processing system, and digital laser projection. This allows practitioners not only to see a virtual real-time image of the underlying vasculature beneath the skin’s surface, but helps them to detect veins more efficiently and provides advice on how to give intravenous injections with the least amount of discomfort to the patient.

Improved physical therapy and rehabilitation

Time is of the essence for people who have survived traumatic injuries. The sooner they begin therapy, the greater the chance that they will restore lost functions.

For cases like these, Neuro Rehab VR uses a gamified approach to physical rehabilitation. The company develops VR training exercises with machine learning in collaboration with physicians and therapists, adapting each activity to the therapeutic needs of patients. The goal is to promote patient participation by making physical therapy more fun.

The fun factor becomes even more important when it’s a case of VR’s potential to aid functional development in children.

According to recent findings, researchers discovered that children with cerebral palsy experienced a significant improvement in their mobility after VR therapy. The study’s authors suggested that this method should be combined with traditional rehabilitation techniques to improve outcomes.

Emergency navigation

Healthcare Apps can also benefit from augmented reality. For example, the AED4EU app, when used in conjunction with Layar reality browser, the first mobile augmented reality browser to hit the market, allows users to add locations where automated external defibrillators, or AEDs can be found.

As a result, augmented reality provides critical information to those in need — they simply have to reach for their phone.

VR as an empathy tool for doctors

Some hospital systems use virtual reality simulations to assist clinicians in establishing sympathetic relationships with their patients. Doctors can be more engaged with their patients’ needs and better grasp what it’s like to be in their patients’ shoes by using VR as a tool for empathy.

In a study at the University of New England, virtual reality was used to simulate age-related disorders. According to the findings, VR enhanced students’ comprehension of age-related health issues and boosted empathy for older people with visual and hearing loss or Alzheimer’s disease.

Researchers at the University of Michigan tackled the empathy problem by using revolutionary virtual human technology called MPathic-VR. Students utilized the program to practice communication skills with a virtual human in real time, which proved to be very helpful when delivering difficult news.
