Laparoscopy – conventional and robotic

Configurable instrumentation for laparoscopic surgery

Based on the multi-DOF SATA technology, Surge-on Medical is developing a new line of configurable and reusable laparoscopic instrument in the 5 to 8 mm range: steerable laparoscopic handhelds.

Characteristics of the steerable handhelds:


  • Configurable instrument tip, providing better reach to surgical areas and superior alignment with critical structures.
  • Reusable, due to its modular design easy to detach, clean and rinse.
  • Operated by two steering wheels that are aligned with the shaft for intuitive instrument tip actuation.

Our innovative instrument designs are fully compliant with future regulations for endoscopic instruments, as visioned by the FDA. This gives us a competitive advantage over all the other devices that are not detachable.


The benefits of laparoscopic surgery with configurable and steerable instrument tips are endless.

Aside of optimizing the articulation and steering mechanisms that we integrated into our instruments, we recently started the development of a wide range of (energy powered) end effectors.

We can adapt to our steerable handheld scissors, atraumatic graspers, needle drivers and clip appliers towards fulfilling the needs of our partners and customers.

Steerable instrumentation for robotic systems

Surge-on Medical is pioneering in the integration of SATA powered instrument tip steering onto a robotic master-slave system.

In a prototype, we demonstrated that a simplified flexor based version of our SATA steering mechanism is promising for a new type of semi-rigid endoscopes or fluid applying instruments due to the large open diameter in the center of the instrument that can be used for fibers, wires or tubing.

The two instrument lines that we are currently developing for robotic surgery have the following benefits:

  • The instrument remains hollow. This open space can be used to facilitate multiple functions in the future.
  • The instrument is easy to clean with prolonged lifespan.
  • If it breaks down, the modular design allows specific part replacement, instead of the entire instrument.

This technology let to the development of our portable robot PoLaRS
