Product Application

Surgical robots

Harnessing robotic technology, proficient medical practitioners execute intricate surgical procedures with unparalleled precision, flexibility, and control, surpassing the capabilities of conventional techniques.

Medical pumps

From bedside infusions to insulin delivery and on-the-go infusions for healthcare professionals in the field, the versatility of medical pumps spans various applications, delivering fluids into a patient's body. This includes a wide array of substances such as nutrients, medications, hormones, or contrast materials, catering to diverse medical needs.

Exoskeletons & Assistive Devices

Unlike powered orthotics or exoskeletons, assistive devices like exoskeletons are crafted to enhance mobility and support individuals with various physical challenges. These innovative solutions serve individuals who may face mobility issues due to injuries, medical conditions, or congenital disorders, providing them with the support they need for improved independence and quality of life.

Surgical tools

While technology, including robotics, is increasingly prominent in the medical arena, many diagnostic procedures still rely on manual intervention. Powered diagnostic tools play a pivotal role in a wide range of medical examinations and procedures, ensuring precision and efficiency in delivering accurate diagnostic results.
