Company profile

researched Aug 2026

Vicarious Surgical is developing a robotic-assisted surgery platform focused on abdominal access and visualization through a single port. The system is designed so that all robotic motion occurs inside the patient's body, entering through a single small incision for the insertion of a camera and two robotic instruments. The company states the system is capable of incision sizes as low as 1.2 cm; currently available disposables require a 1.8 cm incision, and the company is developing disposables intended to require a 1.5 cm incision.

The platform consists of two main components: a patient cart, which interfaces with the patient and facilitates entry of the robot through a single incision while the surgeon retains control of the instrument arms, and a surgeon console, from which the operator drives the robotic instruments and a 3D high-definition camera using proprietary software and hand controllers. The system is also being designed for setup, breakdown, mobility, and storage within medical facilities.

The company describes a staged engineering development path progressing from nine early prototypes to an integrated surgical platform. Vicarious Surgical states that the system's information published on its website represents design goals that have not been evaluated by the FDA other than for the purpose of granting a Breakthrough Device Designation, and that the product is not FDA-cleared and not available for commercial sale in the United States.

▸Full profile — market position, technology, go-to-market, risks & controversies

Market position

Positions itself in robotic-assisted minimally invasive surgery, differentiating on single-port abdominal access, internal articulation and 3D visualization rather than multi-port external robotic arms.

Single-port entry through an incision as small as 1.2-1.5 cm, articulation occurring entirely inside the patient's body, human-inspired arm motion with 28 sensors per arm, 360-degree 3D stereoscopic visualization, and a system designed for mobility, rapid setup and storage in hospital environments.

Technology

The robot is designed to replicate a surgeon's natural upper-body movements from shoulders to elbows to wrists, using 28 sensors per arm. The arms are designed to move in all directions — downward, sideways, upward and backward — with centered pivoting inside the abdomen intended to let the surgeon work from any direction through any entry point. Visualization uses immersive 3D stereoscopic imaging of patient anatomy with responsiveness to the surgeon's movements, delivered via a surgeon console with proprietary software and hand controllers. Placing all robotic motion inside the patient through a single incision is intended to increase freedom of movement and reduce the risk of external instrument collisions around the surgical field.

Go-to-market

Medical facilities and surgical care teams performing robotic-assisted minimally invasive abdominal surgery, with the system positioned around surgeon control and patient recovery outcomes.

Risks & controversies

The system has not been cleared by the FDA and is not for commercial sale in the United States; the company notes that claims on its website represent design goals that have not been evaluated by the FDA aside from evaluations for the purpose of granting a Breakthrough Device Designation. Planned disposables requiring a 1.5 cm incision are still in development.
