Summary
This study introduces a novel sensing system for minimally invasive surgery, enhancing surgeon’s tactile feedback. The system uses photonics sensors to improve tissue interaction perception and surgical navigation.
Area of Science:
- Surgical Technology
- Biomedical Engineering
- Robotics
Background:
- Minimally invasive surgery (MIS) enhances patient recovery but reduces surgeon's tactile and visual feedback.
- Current MIS tools lack advanced sensory capabilities for precise tissue interaction.
Purpose of the Study:
- To present experimental evidence of a novel sensing system for actuated flexible digit elements in MIS.
- To enhance surgeon's perception of tissue contact and interaction during procedures.
Main Methods:
- Integration of a novel sensing system into a steerable flexible digit element for surgical instruments.
- Utilizing four photonics sensing elements for real-time data acquisition.
- Employing a distributive sensory method analyzing coupled sensory data transients.
Main Results:
- The system effectively discriminates types of tissue contact and interaction.
- Quantifiable descriptors like force level and distribution are evaluated.
- Full perception of tissue contact and digit shape is achieved via feedback.
Conclusions:
- The novel sensing system offers a pragmatic solution to improve tactile feedback in MIS.
- The system's polymer construction allows for disposable elements suitable for MRI environments.
- Real-time discrimination of tissue interaction enhances surgical navigation and palpation.
