A Monocular Variable Magnifications 3D Laparoscope System Using Double Liquid Lenses [PDF]

open access: yesIEEE Journal of Translational Engineering in Health and Medicine, 2023
During minimal invasive surgery (MIS), the laparoscope only provides a single viewpoint to the surgeon, leaving a lack of 3D perception. Many works have been proposed to obtain depth and 3D reconstruction by designing a new optical structure or by ...

Calibration‐free structured‐light‐based 3D scanning system in laparoscope for robotic surgery [PDF]

open access: yesHealthcare Technology Letters
Accurate 3D shape measurement is crucial for surgical support and alignment in robotic surgery systems. Stereo cameras in laparoscopes offer a potential solution; however, their accuracy in stereo image matching diminishes when the target image has few ...

Design, simulation and experimental analysis of a monolithic bending section for enhanced maneuverability of single use laparoscopic devices [PDF]

open access: yesScientific Reports
Standard laparoscopes, which are widely used in minimally invasive surgery, have significant handling limitations due to their rigid design. This paper presents an approach for a bending section for laparoscopes based on a standard semi-finished tube ...

Evaluation of a calibration rig for stereo laparoscopes [PDF]

open access: yesMedical Physics, 2023
BACKGROUND: Accurate camera and hand-eye calibration are essential to ensure high quality results in image guided surgery applications. The process must also be able to be undertaken by a non-expert user in a surgical setting. PURPOSE: This work seeks to

A dual-view multi-resolution laparoscope for safer and more efficient minimally invasive surgery [PDF]

open access: yesScientific Reports, 2022
Minimally invasive surgery (MIS) is limited in safety and efficiency by the hand-held nature and narrow fields of view of traditional laparoscopes. A multi-resolution foveated laparoscope (MRFL) was invented to address these concerns.

Improved illumination system of laparoscopes using an aspherical lens array

open access: yesBiomedical Optics Express, 2016
The current fiber-based illumination systems of laparoscopes are unable to uniformly illuminate a large enough area in abdomen due to the limited numerical aperture (NA) of the fiber bundle.
