Keyhole surgeries rely on the use of so-called endoscopes that are essentially camera-guided instruments. Surgeons heavily rely on the visual feedback provided by such endoscopes in performing minimally invasive surgeries. However, the image quality provided by such endoscopes is routinely compromised when body fluids and fogging occlude the lens.
In this project you will explore the use of novel nanomaterial in the role of hydrophobic and anti-fogging layer towards preventing the vision loss after repeated submersions in synthetic blood and similar fluids. The material properties of the coating, including conformability, mechanical adhesion, transparency, and biocompatibility, will be investigated in detail.
This work will be performed in medical and healthcare robotics lab. You will have access to state of the art knee arthroscopes to acquire two sets of images (with and without) to compare the effectiveness of hydrophobic and anti-fogging nanomaterial.
Key activities will include but are not limited to:
- camera calibration and image acquisition using an arthroscope in different recording conditions
- development of a test unit for fog and smudge prevention that is applicable to MIS procedures
- arthoscopic/endoscopic image acquisition and real-time image correction/processing of images
- fabrication and Evaluation of mechanical and optical properties of anti fogging coatings
- optical simulations for optimum layer thickness required to give a balance between desired mechanical and optical properties.
Expected outcomes of this project include:
- exposure to image acquisition systems used in keyhole surgeries
- fabrication and characterisation of nano materials to avoid optical occlusion.
