Robotic surgery has emerged as a transformative innovation in medicine, addressing critical challenges and delivering superior outcomes. Its journey began in the late 20th century, with early robotic systems like the PUMA 560 and the da Vinci Surgical System paving the way. These systems brought unprecedented precision, enabling surgeons to perform minimally invasive procedures that were previously impossible.

Traditional surgical methods face several limitations. Human hands, despite their skill, lack the precision required for microscale movements. Procedures often involve large incisions, leading to longer recovery times and higher risks of complications. Robotic systems overcome these challenges by offering greater dexterity, consistency, and access to anatomically difficult regions. By combining robotics with surgical expertise, robotic surgery enhances precision, reduces invasiveness, and minimizes human error.

Robotic systems offer numerous advantages:

• Minimally Invasive Procedures: Smaller incisions mean reduced blood loss, minimal scarring, and faster recovery.
• Enhanced Precision: Robots can perform sub-millimeter movements, improving outcomes in delicate procedures.
• Improved Visualization: High-definition, 3D imaging provides surgeons with better clarity and control.
• Reduced Fatigue: Robots relieve the physical strain on surgeons during lengthy procedures, maintaining accuracy throughout.

These benefits have made robotic surgery an integral part of modern healthcare.

Despite their remarkable capabilities, robotic surgical systems often lack the tactile or haptic feedback that surgeons rely on in traditional procedures. There are various reasons for this, some are system related, some are sensor related.  The absence of real-time feedback makes it difficult to gauge tissue resistance or pressure, increasing the risk of inadvertent tissue damage. This limitation has spurred innovation in sensor technology to bridge the gap between robotic precision and human sensitivity.

As a leader in sensor technology, HITEC Sensors has developed advanced multi-axis sensors specifically designed to address the demands of robotic surgery. Our sensors are meticulously engineered to measure forces and torques across multiple axes, offering the precise feedback and feel needed for delicate surgical applications.

Our multi-axis sensors are integral to the performance of robotic surgery systems, enabling advancements in several critical areas:

HITEC’s multi-axis sensors represent a pinnacle of engineering and innovation, delivering precise and reliable measurements critical to the success of robotic-assisted surgeries. These sensors are designed to measure forces and torques across six axes: three linear (F_x, F_y F_z) and three rotational (M_x, M_y, M_z). This capability provides comprehensive real-time data that enhances the performance and adaptability of robotic surgical systems.

At their core, multi-axis sensors use advanced strain gauge sensing technologies to detect and measure force and torque in multiple directions.

Strain Gauges: HITEC Sensors uses both bonded foil and semiconductor types depending on the application.  Bonded foil gauges are  thin, flexible components attached to the sensor structure.  Semiconductor gauges are also bonded to the structure but are typically silicon based crystals operating under a similar piezoresistive principle.  When force is applied, the strain gauges deforms slightly, causing a change in electrical resistance. This change is measured and translated into calibrated data about the magnitude and direction of the force.

By integrating these technologies (foil only, semiconductor only, or a mix of the two), HITEC’s multi-axis sensors deliver unparalleled accuracy and responsiveness, ensuring that robotic systems can adapt to the intricate demands of surgical procedures.
