Robotic surgery is transforming the medical field by providing patients with numerous benefits over traditional open surgery. With less pain, blood loss, risk of infection, scarring, hospital stay, and recovery time, robotic surgery is becoming the preferred choice for many patients.

The new colonoscopic surgical robots show improvements in four critical areas: adjustable stiffness, detectability, flexibility, and controllability. For example, the Endotica miniature robotic system uses vacuum mobility similar to an inchworm to improve the accuracy of colonoscopic diagnostics and surgery. The Limited Tendon Motion (CTSM) Coil Mechanism overcomes obstacles with an extended working space and better control of the flexure section. The NeoGuide Colonoscopy System is an advanced soft robot that combines compliance, safe body interaction, actuation, and perception, greater agility, and an increased workspace.

In neurosurgery, the Minimally Invasive Neurosurgical Intracranial Robot (MINIR) uses CTSM with SMA drives for the removal of brain tumors. The Flex System uses variable tension cables to adjust the flexibility of the endoscope, allowing multiple procedures to be performed using only a fraction of the space required by the da Vinci System.

Non-invasive robots are also useful in image-guided therapies, including CyberKnife or image-guided radiosurgery, the first such platform to be approved by the FDA. The use of non-invasive thermotherapy using high-intensity focused ultrasound (HIFU) in combination with robotic manipulators is also described.

The in vivo miniature robots, developed by Virtual Incision and the Center for Surgical Excellence (CAST), represent a new approach in which the entire MIS surgical platform is inserted into the abdominal cavity. They have two arms with multiple functions, with multiple joints for unlimited flexibility. With a miniature entrance incision, miniature hand motors, and a high degree of flexibility, they offer scarless surgery and can be used by inexperienced surgeons under the guidance of veterans, greatly expanding patient access.

Capsule robots are miniature endoscopes that can be used in many diagnostic tests, surgery, or drug delivery. They can be manipulated using magnetic interactions, which provide an untethered structure with tremendous freedom of movement, and they are extremely small, causing less tissue damage and faster accessibility.

Hiring a robot worker for surgical procedures offers numerous benefits for patients and medical professionals alike. With advanced technology and precision, robotic surgery is revolutionizing patient care and improving outcomes.
