SURGICAL SYSTEM WITH SENSORY PERCEPTION FOR ROBOTIC LAPAROSCOPIC SURGERY Russian patent published in 2025 - IPC A61B18/14 

FIELD: medicine.

SUBSTANCE: sensory sensing system for robotic laparoscopic surgery comprises an electrosurgical forceps connected to a surgical instrument, a radiofrequency signal generator for electrocautery and an impedance measurement circuit. Latter includes a measuring sensor for measuring a signal representative of a value corresponding to a contact impedance value between the forceps and the patient's tissue; oscillator; a first electrical circuit with resistors and a voltage limiter for protecting the measuring sensor and the oscillator; and a second electronic circuit with switches. Sensor and the oscillator are connected to the forceps by a power cable of the surgical instrument. Processor connected to the measurement circuit receives said measured signal and converts it into a force vector, is a function of the measured contact impedance, and the argument is a function of the traversed trajectory.

EFFECT: use of this group of inventions enables to determine properties of tissue/tissues and to quantify the contact force applied to the tissue/tissues in the process of a remote surgical intervention by a sensory back channel.
