A3.3 - A Miniaturised Piezoresistive Multi-Component Force Sensor for Minimally Invasive Surgery

Jacqueline Rausch & Roland Werthschuetzky
Conventional tools used in minimally invasive abdominal surgery (MIS) suffer from workspace restrictions and loss of haptic perception of the manipulated tissue. Operations are more complicated, expert surgeons are needed and longer operation time is the consequence. On this, a novel hand-held instrument with a force feedback system for gentle manipulation of soft tissue is being developed. Driven by integrated piezoelectric actuators an operation platform with four additional degrees of freedom carries manipulators and positions...
