AKTORmed, based in Regensburg, Germany, develops robotic assistance systems for minimally invasive surgery. Its Soloassist II robotic arm is designed to guide and position an endoscope during laparoscopic procedures, helping surgeons maintain a stable view of the operating field while reducing dependence on manual camera guidance.
Minimally invasive surgery relies on a laparoscope or endoscope to provide a visual reference of the surgical field through small incisions. Maintaining a stable and accurately positioned image is therefore essential throughout the procedure. Robotic camera guidance systems can help the operating surgeon control the position of the endoscope more consistently and reduce dependence on manual camera handling.
SOLOASSIST II is designed to hold and position a rigid laparoscope or endoscope during minimally invasive surgery. The system provides 360° rotation, tilt of up to 90° and more than 300 mm of zoom movement, giving the surgeon controlled positioning of the endoscope throughout the procedure.
SOLOASSIST II can be operated using different control interfaces, including joystick, remote control and voice control. With the voice control option, the surgeon can issue directional and zoom commands while keeping both hands available for the surgical procedure. The system also allows positions to be stored and offers three preset movement speeds.
Compact linear motion is an important part of many automated medical systems, particularly when movement must be integrated into a limited space. In the SOLOASSIST II application, a REGNER RAMINI microactuator provides the linear movement required within the robotic system.
In medical equipment, motion control must be considered as part of the complete system. Positioning, available space, control architecture, mechanical integration and the operating profile all influence the selection of the actuator. For OEM applications, this makes early integration between the device manufacturer and the actuator supplier particularly important.
The RAMINI microactuator was selected for integration into the SOLOASSIST II, where compact dimensions and controlled linear motion are important design requirements. Its integration shows how a linear microactuator can become part of a larger robotic architecture without occupying unnecessary space inside the device.
RAMINI is designed for applications where compact dimensions and controlled linear movement are required. In OEM medical equipment, parameters such as stroke, force, speed, mounting, electrical connection and control interface must be considered together to achieve an effective integration within the final device.
REGNER works with equipment manufacturers to adapt microactuation solutions to the mechanical and electrical requirements of each project, helping integrate motion into devices where available space and system architecture are critical design constraints.
The SOLOASSIST II case illustrates how compact linear actuation can be integrated into a medical robotic system as part of a broader motion and control architecture. For actuator manufacturers, understanding the complete application is essential when developing components for medical equipment with demanding requirements for space, movement and integration.
REGNER develops electric linear actuators and microactuation solutions for OEM medical equipment, taking into account the mechanical, electrical and control requirements of each application. If your project requires compact motion, specific integration constraints or a customised actuator configuration, our engineering team can help you evaluate the most suitable solution.
On 26–27 August 2026, REGNER’s engineering team visited All About Automation Zürich, held alongside maintenance Schweiz at Messe Zürich, to take stock of the latest trends in motion control, collaborative robotics and mechatronics — and to compare them against REGNER’s own developments in diagnostic-ready linear actuators.
Choosing a microactuator for analytical instrumentation takes more than force, speed and stroke. These are the seven technical questions an OEM engineer should answer before deciding, drawn from REGNER’s experience with instrumentation manufacturers.
Oriol Garay, a Materials Engineering student at the UPC, has joined REGNER to work on an applied tribology project focused on the interface between the lead screw and the nut. The project will examine how surface treatments and finishes affect friction, wear and the functional repeatability of microactuators.
Expoquimia and Equiplast 2026 confirmed that water management has become a strategic priority for the process industries. This evolution calls for more compact, automated and reliable systems to monitor, dose and control fluids precisely in analytical instrumentation and treatment equipment.
