Summary
This study introduces an all-optical method for tracking surgical needles using fluorescent markers in simulated tissues. This technique enhances minimally invasive surgery safety and shows potential for robot-assisted procedures.
Area of Science:
- Biomedical Engineering
- Optical Imaging
- Surgical Technology
Background:
- Minimally invasive surgery (MIS) relies on advanced imaging for safety.
- Current techniques often involve complex imaging equipment.
- There is a need for simpler, optical-based tracking methods in MIS.
Purpose of the Study:
- To explore an all-optical alternative for tracking surgical needles in simulated tissues.
- To evaluate fluorescent markers for real-time needle tip localization.
- To assess tissue characterization capabilities using photoluminescence.
Main Methods:
- Investigated inorganic (Perovskite, PbS) and organic (carbon dots, Rhodamine 6G) fluorescent nanoparticles.
- Utilized Rhodamine 6G dye for its high fluorescence signal.
- Tracked a surgical needle within homogeneous and inhomogeneous gelatin tissue models.
Main Results:
- Successfully tracked a surgical needle's 3D position in simulated tissues.
- Demonstrated the potential of fluorescent markers for identifying tissue layers of varying stiffness.
- Rhodamine 6G proved effective for needle tracking due to its strong fluorescence.
Conclusions:
- An all-optical photoluminescence technique shows promise for in vitro needle tracking.
- This method can enhance safety and real-time feedback in minimally invasive procedures.
- Potential for future application in robot-assisted needle insertions during in vivo surgeries.
