The phrase “robotic surgery” can create the impression that a machine is independently carrying out an operation. That is not how current commercial systems work.

The FDA is explicit: robotic-assisted surgical devices remain under direct human control. The surgeon operates from a console, viewing the surgical field and controlling the movements of the instruments attached to the robotic arms. The robot may translate, scale or refine those movements, but it cannot perform the procedure without the surgeon.

That distinction matters. The surgeon is still making the decisions, applying clinical judgement and responding to anatomy in real time. But those decisions are transmitted through a complex chain of digital and mechanical technology before they reach the tissue. Every link in that chain has to behave as intended.

A control input may be translated into movement through multiple joints and interfaces before reaching the end of a wristed instrument. Intuitive’s EndoWrist instruments, for example, offer seven degrees of freedom, while systems such as Versius use small, fully wristed instruments intended to provide dexterity and accuracy within minimally invasive procedures.

The more articulation, control and functionality an instrument provides, the more carefully its constituent parts must work together.

In robotic surgery, precision is often discussed in terms of the accuracy of the robot’s movement. From a manufacturing perspective, however, precision has a broader meaning.

It means producing complex geometries consistently. Maintaining the relationship between connected parts. Controlling surfaces, dimensions and interfaces. Selecting materials that can withstand repeated mechanical use and, where relevant, cleaning and sterilisation. It also means ensuring that manufacturing variation does not gradually undermine the performance designed into the instrument.

A small gripping pad, jaw insert, pin, drive feature or machined interface may help determine whether an instrument closes correctly, moves smoothly or holds tissue and materials securely. Robotic platforms can offer extraordinary control at the console, but that control must still be converted into dependable physical action at the instrument tip.

This is where Serrations provides a particularly relevant example. The business manufactures tungsten carbide gripping inserts used in surgical instruments such as needle holders and tweezers. These inserts are designed to help the instrument grip securely without slipping when accuracy matters most. Serrations grinds individual teeth into hardened tungsten carbide, laps the components to controlled thicknesses and checks every part throughout the manufacturing process.

Serrations is already working with around 20 robotic surgery companies developing systems internationally. One customer progressed from purchasing small trial quantities to ordering 6,000 inserts each month. That is a useful illustration of how a relatively specialised component can become increasingly important as a robotic platform moves from development into broader production.

The growth of robotic surgery will not only increase demand for individual components. It will increase the need to manufacture those components repeatedly, consistently and at greater scale.

A prototype may prove that a mechanism works. Commercialisation asks a harder question: can it work in the same way across hundreds or thousands of instruments?

That requires much more than achieving a target dimension once. It requires controlled processes, reliable tooling, appropriate inspection, traceability and the ability to understand how variation across several parts may accumulate within an assembly.

This is particularly important in systems designed to translate fine surgeon movements into equally fine instrument actions. The mechanical performance expected at the instrument tip can be affected by the combined behaviour of every interface behind it.

As robotic surgery expands, medical-device innovators are therefore likely to need manufacturing partners that can contribute earlier. Design for manufacture, prototyping and feasibility work become essential in identifying parts that are unnecessarily difficult to produce, assemble or inspect before those problems become embedded in a commercial design.

AI increases the value of good hardware; it does not remove it Artificial intelligence and data analytics are also becoming more prominent within robotic-surgery ecosystems.

Medtronic’s Hugo system, for example, is accompanied by the Touch Surgery ecosystem, which uses surgical video and performance data to provide analytics and support continuous improvement. CMR similarly positions its digital ecosystem around actionable data and insights.

Arguably, it makes dependable hardware even more important. Data can only describe the performance of the system that generated it. An intelligent platform still depends on stable, repeatable mechanical behaviour if its analytics are to be useful and if surgeons are to build confidence in how the system responds.

AI may help teams understand performance, identify patterns and improve workflows. It cannot compensate indefinitely for an instrument that grips inconsistently, an interface that wears unpredictably or a component that varies from one manufactured batch to another. The digital and physical elements have to advance together.
