About Asensus Surgical

Asensus Surgical, now a part of the KARL STORZ family, is at the forefront of revolutionizing minimally invasive surgery by integrating advanced digital solutions, robotics, and augmented intelligence (AI). Their core offering, the Senhance Surgical System, and the next-generation LUNA Surgical System, are powered by the Intelligent Surgical Unit (ISU). This technology aims to digitize the interface between the surgeon and the patient, providing capabilities such as machine vision, deep learning, and real-time surgical guidance. The goal is to enhance surgeon control, reduce procedural variability, and ultimately lead to consistently superior patient outcomes in various laparoscopic procedures.

For physicians, the Senhance Surgical System offers features designed to improve the surgical experience and patient care. These include enhanced control through surgeon eye-sensing camera control and 3DHD vision, improved precision via tremor filtration and robotic stabilization, and enhanced focus due to optimized ergonomics and haptic feedback—a first in robotic surgery. The Intelligent Surgical Unit (ISU) captures and analyzes laparoscopic video feeds, delivering actionable, real-time information to surgeons during the procedure. This “Performance-Guided Surgery” approach leverages AI to provide insights beyond traditional robotic capabilities, akin to a GPS system for surgery, which becomes smarter as surgeons build their digital legacy.

Asensus Surgical’s commitment extends to addressing clinical, cognitive, and economic challenges in surgery. Their systems are designed to be cost-effective, utilizing reusable 3mm and 5mm instruments to align with sustainability goals and offer a responsible pricing model similar to traditional laparoscopy. The company’s focus on augmented intelligence and digital surgery platforms aims to make advanced surgical techniques more accessible and predictable, benefiting patients, surgeons, and hospitals worldwide.

What Physicians Need to Know

Robotic Surgery & Surgical Robotics
Asensus Surgical specializes in advanced robotic-assisted surgery with its Senhanceu00ae Surgical System, designed to provide surgeons with an unprecedented level of control and precision. The system features robotic precision with selectable scaling for delicate tasks and offers a broad portfolio of 3mm and 5mm fully reusable instruments, which are among the smallest available on a robotic surgical platform. They are also developing LUNAu2122, their next-generation robotic surgery system.
Augmented Intelligence & Digital Laparoscopy
At the core of Asensus Surgical's offerings is Augmented Intelligence (AI), powered by the Intelligent Surgical Unitu2122 (ISUu2122). This technology goes beyond traditional robotics by providing real-time insights, processing data, and presenting information to surgeons to enhance their capabilities rather than replace them. The ISU integrates innovative digital tools with advanced surgical robotics, offering features like AI Sight (eye-tracking camera control), AI Precision (intraoperative measurement), and AI Annotation (digital tagging) to support decision-making and improve surgical efficiency. The Senhance System is the first digital laparoscopic platform to leverage augmented intelligence.
Performance-Guided Surgery
Asensus Surgical is pioneering a new era of Performance-Guided Surgery (PGS) by digitizing the interface between the surgeon and patient. PGS combines advanced robotic manipulation, real-time Augmented Intelligence, and machine learning to generate and enhance intraoperative insights, aiming to reduce surgical variability and enable consistently superior outcomes. This framework includes pre-operative simulation and training, intraoperative real-time digital tools, and post-operative data analysis for continuous improvement.
Computer Vision & Deep Learning
The company utilizes computer vision and deep learning capabilities to enable its robotic-assisted surgery platform to perceive, learn, and assist surgical decision-making in real-time. This technology allows for automatic identification of anatomical structures and safety hazards, providing critical insights during procedures. They are actively enhancing their platforms through advanced AI, computer vision, and machine learning, including for their next-generation LUNA system.
Minimally Invasive Surgery
Asensus Surgical's technology is designed to enhance minimally invasive surgery (MIS) by providing greater precision and control, with the goal of smaller incisions, less pain, and shorter recovery times for patients. The Senhance System maintains familiar laparoscopic techniques while upgrading safety and efficiency, making it accessible for surgeons already skilled in laparoscopy.
Physician Tip

For physicians, Asensus Surgical's Senhanceu00ae Surgical System, powered by the Intelligent Surgical Unitu2122 (ISUu2122) and its Augmented Intelligence, offers several key advantages. The system provides real-time, data-driven insights during surgery, helping to lighten cognitive load and support more efficient, precise, and safe medical decisions. Surgeons benefit from enhanced precision and control through robotic manipulation, including selectable scaling and articulating instruments. nnUnique features like haptic feedback transmit forces to the surgeon's hands, providing heightened awareness and an added layer of security. Eye-tracking camera control allows for intuitive navigation of the surgical field, freeing up assistants and enabling the surgeon to maintain focus. The system's improved ergonomics, with a comfortable seated position and an open cockpit, aim to increase surgeon career longevity and facilitate clear communication with the surgical team. nnFurthermore, the use of reusable 3mm and 5mm instruments not only supports less invasive procedures but also offers a responsible per-procedure pricing model similar to traditional laparoscopy. The digital tools for intraoperative measurement (AI Precision) and annotation (AI Annotation) enhance procedural reproducibility and team coordination. The Senhance system is also designed for multi-specialty and multi-quadrant use, applicable in general laparoscopic, gynecological, and colorectal surgeries, and is indicated for both adult and pediatric patients.

Asensus Surgical's Senhanceu00ae Surgical System features an open-platform architecture, allowing for compatibility with 3DHD and HD fluorescence vision systems, as well as integration with other existing hospital investments in laparoscopy. The Intelligent Surgical Unitu2122 (ISUu2122) is designed to integrate with the Senhance System and is compatible with a wide selection of laparoscopic camera platforms. Asensus Surgical has a strategic collaboration with Google Cloud to integrate secure cloud data architecture and machine learning technologies to expand the capabilities of their Performance-Guided Surgery framework. They also partner with KARL STORZ, a global leader in medical technologies, to market and sell the ISU as a standalone device and integrate it into KARL STORZ's laparoscopic vision systems. Eye trackers for the Senhance System are supplied by Tobii. Additionally, Asensus Surgical has partnered with GlobalLogic to develop their next-generation LUNAu2122 robotic surgery system and enhance their intelligent surgical platforms through advanced AI, computer vision, and machine learning.
