Robotics Help Medical Providers Improve Care

By Wayne Shockloss | February 02, 2021

A new generation of robotic medical equipment is helping medical providers deliver automated care protocols, sterilize facilities, and conduct surgical procedures, as well as reduce risk and improve patient outcomes.

Surgical suites and intensive care units are some of the most high-risk work environments within hospitals. It is imperative to clean, disinfect, and sterilize surgical suites, patient rooms, and equipment between patients. The presence of highly infectious airborne pathogens like COVID-19 calls for even more stringent cleaning processes. The cleaning of medical devices and electronic systems must be accomplished using appropriate methods, and these devices are themselves becoming important tools in sterilization protocols.

SmartUVC’s Tru-D UVC disinfection robot (pictured here) uses UVC light (ultraviolet C radiation with 200–280nm wavelengths) to safely, efficiently, and effectively disinfect patient rooms, intensive care units, operating rooms, emergency rooms, and long-term care facilities. The medical robot deconstructs the DNA of even deadly pathogens that could compromise patient outcomes, allowing hospital staff to disinfect with ease and confidence.

Robotic Disinfection Equipment

To eliminate harmful bacteria and viruses, one of the most common germ-zapping technologies available for hospitals is ultraviolent light, specifically UVC, which utilizes the C frequency of the electromagnetic family of light frequencies. Offering 99.9% effectiveness at killing the DNA and RNA in viral pathogens, these light-based processes use wavelengths from 200–280 nanometers, delivered via handheld wands or robots designed to illuminate targeted areas with UVC light, effectively damaging viruses beyond recovery and stopping them from replicating and spreading infection. UVC has been recognized by the U.S. Center for Disease Control (CDC) and the U.S. Food & Drug Administration (FDA) as an approved method for disinfecting N95 face masks, medical supplies, and other personal protective equipment (PPE) during the pandemic.

UVC disinfection devices can be stationary or portable and are frequently operated by healthcare workers, who take on some exposure risk in the process. However, a new generation of robotic UVC disinfection equipment requires no human presence in infected areas. Autonomous robots can be programmed to disinfect entire rooms or specific areas and can be programmed to operate at preset times in routes within surgical suites, ICUs, COVID-19 suites, and other hospital environments. Sophisticated robotic systems may include lasers and passive infrared (PIR) motion sensors to detect and avoid obstacles in hospital rooms, hallways, elevators, and automated door vestibules. When autonomous UVC systems detect the presence of human beings, they turn off the emission of UVC light to ensure hospital staff and patient safety.

A growing number of companies is emerging in the specialized robotic disinfection market, including Akara Robotics, Finson Technologies, HELIOS, Keenon Robotics, LG, Omron,R-Zero, Sherpa Mobile Robotics, Siemens/Aucma, Skytron, TMI Robotics, TRU-D SmartUVC, UVD Robots, a subsidiary of Blue Ocean Robotics, XD Bot, and Xenex Disinfection Services. Based on UVC’s proven safety and effectiveness, experts predict that the use of this technology will become a widespread standard disinfection protocol used throughout hospitals and other medical facilities.

The global robotic disinfection market reached $343 million in 2019 and is expected to reach $2.3 billion by 2025 with a CAGR exceeding 36%, which could well be a conservative estimate. This growing demand for robotic equipment is pushing the electronics industry to provide connectors, cable assemblies, and sensor solutions that can endure the harsh operating conditions of both medical environments and sterilization processes.

TE Connectivity solutions for medical robotics

TE Connectivity’s wire-to-board and wire-to-wire connectivity solutions include signal and power connectors that enable connectivity between circuits and are well-suited for use in robotic disinfection equipment. TE’s wire-to-board connectors are designed for low-profile mating and secure terminations and are available with friction lock and full lock mechanisms. Its LCEDI connectors support both low-voltage differential signaling (LVDS) and embedded DisplayPort (eDP) applications, which are commonly used in medical imaging, surgical, and therapeutic applications.

Mill-Max Hybrid power and signal connectors for harsh environments like medical robotics

Mill-Max offers hybrid power and signal connectors designed to streamline device architectures and deliver reliable performance, including a compact, five-pin cable-to-board header and socket and a 40-pin board-to-board header and socket combination. The five-pin connectors have two contacts for power and three for signal, while the 40-pin connectors have 30 signal contacts and 10 power contacts, and both connectors are well-suited for critical applications in harsh environments.

Innovation Fuels Growth and Investments in Surgical Robotics

Newer robotic assisted devices include more unique features than earlier iterations and are trending smaller, more portable, and more affordable. The rising use of AI, automation, enhanced connectivity, haptic sensor technology, and other advanced technologies is enabling surgical robots to achieve higher levels of precision and putting more control in the hands of surgeons. New entrants have taken notice and are investing heavily in specialty surgical robotic companies and technologies to get in on the action. 

Robot-assisted surgery enables surgeons to perform many types of complex procedures with more precision, flexibility, and control than is possible with conventional techniques. Surgeons who use robotic systems find that this technology minimizes potential hand tremors or shakiness, provides more control, and allows for a better line of sight compared to traditional techniques. Some of the most notable patient benefits of minimally invasive robotic surgery include fewer complications, reduced likelihood of infection, less overall pain and blood loss, smaller incisions, less noticeable scaring, and quicker recovery.

Mako Surgical, a Stryker company, launched the Mako SmartRobotics platform (left) in 2017. This device combines 3-D imaging, AccuStop haptic technology, and insightful data analytics into a portable platform to improve patient outcomes for total knee, total hip, and partial knee replacements. In January 2021, Stryker announced the acquisition of OrthoSensor and its VERASENSE Sensor-Assisted Total Knee Arthroplasty technology (center and right), which enables surgeons to quantify ligament balance and customize knee implant position using a disposable wireless smart device.

When market-leader Intuitive Surgical introduced its da Vinci robotic surgical system more than 20 years ago, it was initially used for cardiology, urology, and gynecology procedures. Since then, robotic-assisted surgical procedures have expanded to include general surgeries, gallbladder removals, hernia repairs, orthopedic hip and knee replacements, spinal surgeries, laparoscopic and endoscopic visualization procedures, lung cancer treatments, and more.

Senhance digital robotic surgery system

In 2020, TransEnterix obtained FDA 510k clearance for its Senhance digital robotic surgery system, which is challenging the market-leading Intuitive da Vinci surgical system with features including haptic force feedback that heightens surgeons’ sense of pressure and tension, an eye-tracking camera that senses surgeons’ eye activity for greater camera control, and high-definition 3-D visualization for intelligent depth perception and enhanced visual recognition.

Many market-leading companies are making significant investments in surgical robotics, including Abbott, Becton Dickinson/BARD, Boston Scientific, CMR Surgical, Curexo Technologies, Hanson Medical, Intuitive Surgical, Johnson & Johnson, Medrobotics, Medtronic, Qiagen N.V., Siemens/Corindus, Stryker, Tecan Group, THINK Surgical/Robodoc, Titan Medical, and TransEnterix.

Hybrid and modular interconnect solutions that have the ability to combine signal, power, fiber, and other mediums are widely preferred by designers of surgical robotic systems. User-friendly mating and the ability to withstand rigorous cleaning, disinfection, and sterilization is the norm for interconnect solutions used in surgical and other medical equipment.
