CataNet: Predicting remaining cataract surgery duration [PDF]

arXiv, 2021
Cataract surgery is a sight saving surgery that is performed over 10 million times each year around the world. With such a large demand, the ability to organize surgical wards and operating rooms efficiently is critical to delivery this therapy in routine clinical care. In this context, estimating the remaining surgical duration (RSD) during procedures

Liquid-Solid Phase Transition Alloy as Reversible and Rapid Molding Bone Cement [PDF]

arXiv, 2013
Bone cement has been demonstrated as an essential restorative material in the orthopedic surgery. However current materials often imply unavoidable drawbacks, such as tissue-cement reaction induced thermal injuries and troublesome revision procedure.

Numerics on the trajectory of nodule displacements by external compressions of the breast [PDF]

arXiv, 2019
We present a fast and reliable algorithm that gives precise location of breast tumours for a partial mastectomy. Our algorithm is fully implemented in the Surface Evolver, which is a general-purpose simulator of physical experiments. By starting from the X-rays images that show a tumour one takes its 2D coordinates in each view.

Assessment of Biomechanical Properties for Corneal Post Refractive Surgery [PDF]

arXiv, 2022
A stable shape for corneas experiencing refractive surgery has to be sustained so as to elude post-refractive surgery de-compensation. This de-compensation leads to visual complications and unsatisfactory procedure recovery. Variation in corneal lamellae and collagen fibres is induced by recent LASER refractive surgical procedures utilizing LASER ...

Vector variational problem with knitting boundary conditions [PDF]

arXiv, 2015
We consider a variational problem with a polyconvex integrand and nonstandard boundary conditions that can be treated as minimization of the stress energy during the suturing process in the plastic surgery. Ex- istence of minimizers is proved as well as necessary optimality conditions are discussed.

On Matching Faces with Alterations due to Plastic Surgery and Disguise [PDF]

arXiv, 2018
Plastic surgery and disguise variations are two of the most challenging co-variates of face recognition. The state-of-art deep learning models are not sufficiently successful due to the availability of limited training samples. In this paper, a novel framework is proposed which transfers fundamental visual features learnt from a generic image dataset ...

Strain gradient visco-plasticity with dislocation densities contributing to the energy [PDF]

arXiv, 2017
We consider the energetic description of a visco-plastic evolution and derive an existence result. The energies are convex, but not necessarily quadratic. Our model is a strain gradient model in which the curl of the plastic strain contributes to the energy.

Real-time Surgical Tools Recognition in Total Knee Arthroplasty Using Deep Neural Networks [PDF]

arXiv, 2018
Total knee arthroplasty (TKA) is a commonly performed surgical procedure to mitigate knee pain and improve functions for people with knee arthritis. The procedure is complicated due to the different surgical tools used in the stages of surgery. The recognition of surgical tools in real-time can be a solution to simplify surgical procedures for the ...

A 3D Finite Element model of the face for simulation in plastic and maxillo-facial surgery [PDF]

Lecture notes in computer science (LNCS) 1935 (2000) 1068-1075, 2006
This paper introduces a new Finite Element biomechanical model of the human face, which has been developed to be integrated into a simulator for plastic and maxillo-facial surgery. The idea is to be able to predict, from an aesthetic and functional point of view, the deformations of a patient face, resulting from repositioning of the maxillary and ...

General surgery vision transformer: A video pre-trained foundation model for general surgery [PDF]

arXiv
The absence of openly accessible data and specialized foundation models is a major barrier for computational research in surgery. Toward this, (i) we open-source the largest dataset of general surgery videos to-date, consisting of 680 hours of surgical videos, including data from robotic and laparoscopic techniques across 28 procedures; (ii) we propose
