Novel magnetic anchored endoscopes offer a solution to port crowding in uniportal video-assisted thoracic surgery (VATS). These wirelessly actuated endoscopes are designed for improved ergonomics and maneuverability in confined thoracic spaces.
Area of Science:
- Medical Devices
- Surgical Technology
- Thoracic Surgery
Background:
- Rod lens endoscopes have been pivotal in advancing video-assisted thoracic surgery (VATS).
- The emergence of uniportal VATS necessitates innovations in surgical instruments to address limitations like trocar crowding and instrument interference.
- Existing articulated flexible endoscopes offer expanded views but still face challenges in crowded surgical sites.
Purpose of the Study:
- To design novel magnetic anchored and steered endoscopes specifically for uniportal VATS.
- To overcome the spatial constraints and port crowding issues inherent in single-incision thoracic surgery.
- To develop wirelessly actuated endoscopic solutions that enhance maneuverability and surgeon ergonomics.
Main Methods:
- Design and conceptualization of two distinct magnetic anchored endoscope prototypes.
- One prototype features a soft, silicone rubber body for safety and compactness.
- The second prototype is a compact 40 mm capsule designed for optimal fit within VATS spatial constraints.
- Wireless actuation via magnetic interaction is employed for both designs.
Main Results:
- Successful design of two novel magnetic anchored and steered endoscopes tailored for uniportal VATS.
- The developed endoscopes are wirelessly actuated, addressing the need for reduced instrument crowding.
- One design prioritizes a lightweight, safe soft body, while the other offers a compact capsule form factor optimized for thoracic surgery environments.
Conclusions:
- Magnetic anchored endoscopes present a promising alternative to traditional rigid rod endoscopes in uniportal VATS.
- The novel designs address key limitations of current flexible endoscopes, offering improved maneuverability and reduced port occupancy.
- These innovations have the potential to enhance surgical technique and patient outcomes in minimally invasive thoracic procedures.
