How Does a Surgical Robot Work Step by Step? Technology, Team, and the Surgical Procedure

How Does a Surgical Robot Work? The Technology Behind It

A surgical robot is not an autonomous device—it is an advanced telemanipulation system that replicates the surgeon’s movements in real time.

Robotic systems were developed to address some of the limitations of laparoscopy, such as:

• 2D visualization
• Limited range of instrument motion
• Ergonomic challenges for surgeons

Modern robotic platforms significantly reduce these limitations through:

• High-definition 3D visualization
• Tremor filtration
• Motion scaling to enhance precision in selected procedures
• Greater freedom of instrument movement

What Components Make Up a Robotic Surgical System?

Using the KANGDUO Robot SR2000 as an example, a robotic surgical system consists of four main components:

1. Surgeon Console

This is the surgeon’s workstation. The surgeon sits at the console and controls the system while viewing the surgical field in 3D.

2. Patient Cart with Robotic Arms

The robotic arms precisely replicate the surgeon’s hand movements while providing a greater range of motion than the human hand.

3. Vision Cart

The vision cart houses the endoscopic camera system, which delivers a high-quality view of the surgical field.

4. Surgical Instruments

Specialized instruments enable surgeons to perform complex minimally invasive procedures with a high degree of precision.

What Does a Robotic Procedure Look Like? Step by Step

1. Patient and Team Preparation

The procedure takes place in an operating room, similarly to laparoscopic surgery.

The surgical team typically includes:

• The surgeon
• A surgical assistant
• An anesthesiologist
• Nursing staff

2. Surgical Access (Small Incisions)

Small incisions are made through which surgical instruments and the camera are inserted into the patient's body.

3. Robot Positioning

The robotic system is positioned in relation to the patient, operating table, and surgical team in order to:

• Ensure optimal access to the surgical field
• Avoid collisions between robotic arms
• Enable smooth cooperation between the surgeon and the bedside team

4. Surgeon Control

The surgeon sits at the console and controls the robotic system.

The system:

• Filters hand tremors
• Scales movements (for example, a larger hand movement can be translated into a highly precise micro-movement of the instrument)

5. Performing the Procedure

Robotic technology makes it possible to:

• Operate in anatomically challenging areas
• Minimize tissue trauma
• Achieve greater precision during tissue dissection and anatomical structure identification

Research indicates that robotic surgery may, in certain procedures, be associated with:

• Reduced blood loss
• Shorter hospital stays
• Lower complication rates

6. Completion of the Procedure

Once the procedure is completed, the instruments are removed and the incisions are closed.

The patient is then transferred to the recovery or postoperative care unit.

What Is the Role of the Surgeon and What Is the Role of the Robot?

This is one of the most common questions about robotic surgery.

The answer is simple:

• The surgeon makes every clinical decision and performs every movement.
• The robot reproduces those movements and enhances their precision.

The system has no autonomy. A surgical robot is a tool—it does not replace the surgeon.

How Is KANGDUO Used in Practice?

As Beryl Med, we are responsible for the distribution of the KANGDUO Robot SR2000 across 15 Central European countries and are actively developing its presence throughout the region.

In recent months, the system has:

• Been evaluated at our headquarters in Józefów, Poland
• Been presented during industry events, including the Congress of the Polish Society of Surgeons
• Been used in training programs, including those conducted at the Medical University of Warsaw
• Been tested at the University Clinical Hospital No. 4 in Lublin

Since April 2026, the system has been installed at Mazovia Hospital in Ząbki, where it is being prepared for its first clinical procedures.

Why Are Surgical Robots So Important for the Future of Medicine?

The development of medical robotics is one of the most significant trends in modern healthcare.

Clinical experience and scientific research indicate that robotic technology can:

• Increase surgical precision
• Improve surgeon ergonomics
• Enable the development of new surgical techniques
• Support treatment in oncological surgery

At the same time, the market continues to expand rapidly. New manufacturers are entering the field, increasing competition and improving access to robotic technologies worldwide.
