Today, robots in combination with AI use the data from past operations to perform new surgeries and are yielding much better results.

To the patients, robots mean reduced hospital-stay and fewer complications. Robots are extensively being used for surgical procedures such as orthopedic, urological, bariatric, gynecological, and many others. The surgical-robots hold substantial future growth potential. To gain a competitive advantage, some of the key companies at the global level, such as Intuitive Surgical, Johnson & Johnson, Zimmer Biomet, Stereotaxis, Accuray, Smith & Nephew, Mazor Robotics, Auris Health, Globus Medical, Stryker, Siemens Healthineers (Corindus), and Medtronic are involved in developing surgical robots. 

Clinical Training – Clinical Training Robots are realistic simulation devices that can enhance the healthcare provider’s skills and knowledge. One of the latest and most advanced examples of a training robot is Pediatric Hal. Pediatric Hal is an artificial intelligence robot manufactured by Gaumard Scientific. Pediatric Hal can mimic like a five-year-old child and exhibit symptoms of cardiac arrest and arrhythmia. It can also perform a dozen of facial expressions, mimic crying, and imitate rapid breathing, providing a real “working under pressure” condition to the healthcare trainees. 

Prescription Dispensing / sensitive materials – Dispensing robots are used to distribute medication and handle sensitive materials in hospital settings. Dispensing robots are quite beneficial as they can dispense medicine at a very high speed and accuracy. Similarly, they can also handle sensitive liquids or viscous materials. 

Care/Services – The demand for robots in the care segment is also increasing significantly. The challenges faced by the elderly population and the people affected by dementia and other mental diseases is the main driver for care robot demand. Care robots help patients perform some necessary day-to-day activities such as providing mobility and transportation support, performing routine body check-ups (like temperature, blood pressure, sugar levels), fetching food and water, reminding medication, and many others. The care robots are quite handy and ease the daily burden on healthcare professionals. With the increase in capabilities and growing aging population, the demand for care robots is likely to increase in the coming years. 

Disinfection and Sanitation – Lack of hygiene and poor sanitation can lead to many diseases, and to carry out the disinfection and sanitation process, hospitals are deploying robots. These specialized robots scan the hospital environment and carry out the air circulating and surface disinfection process. UV sterilization robots, in particular, kill bacteria, viruses, and other harmful microorganisms that can cause infections. Due to the Covid-19 pandemic, the disinfection and sanitation robots segment observed a significant demand. Blue Ocean Robotics, Intellibot Robotics LLC, IRobot Corporation, Skytron, Bioquell, Ecovacs Robotics, Lumalier Corp, Siemens are some of the key companies involved in developing disinfection and sanitation robots at the global level. 

Telepresence – Telepresence, also known as Telemedicine Robots, makes it accessible for the doctor to connect with the patient from remote locations. 

Surgical Robots – Robots are now employed to performed surgery. Surgical Robots are capable of performing sophisticated surgical procedures through small incisions with minimal scarring. These robots are equipped with high-definition 3-D cameras, mechanical arms, and several other small tools.

Logistics/Delivery  – To perform hospitals’ logistics tasks, a new type of robot called logistics robots are available in the market today. The logistics robots are equipped with navigation systems that help them to perform basic tasks such as moving food and water, lab samples, beddings, and medications within the hospital premises. 

Rehabilitation Robots, Receptionist Robots, Nursing Robots, Ambulance Robots, and Physical Therapy Robots are also generating significant demand.

What are the Major Benefits of Robotics in Healthcare?

In the medical field, robots are changing how surgeries are performed, streamlining supply delivery and disinfection, and freeing up time for providers to interact with patients. Robots are now used in clinical settings to assist health workers and improve patient care, in addition to the operating room. During the COVID-19 pandemic, hospitals and clinics began using robots for a broader range of tasks to help reduce pathogen exposure. It has become clear that the operational efficiencies and risk reduction provided by health robotics add value in a variety of ways. Robots offer a variety of benefits of robotics in healthcare. For example, robots can clean and prepare patient rooms on their own, reducing person-to-person contact in infectious disease wards. Robots in healthcare are equipped with AI-enabled medicine identifier software to shorten the time it takes to identify, match, and distribute medicine to patients.

Furthermore, the extensive use of robots in delivering healthcare services makes it crystal clear that the use of robots is going to be a common sight in near future.
