“…Kappert et al (5) reported 29 successful beating heart TECAB procedures. To date, we have performed 16 successful single-vessel beating heart TECAB procedures (1,2). The rate of conversion to another minimally invasive or standard approach is still approximately 30%.…”

“…The experience gathered from TECAB on the arrested heart is expected to become a milestone for more complex procedures such as off-pump or multivessel TECAB (1). Despite the first TECAB on the beating heart being reported in 2001, the number of these procedures has not approached to the desired level and CPB still remains a prerequisite for TECAB (2).…”

“…Tissue deformation combined with restricted workspace and visibility of an already cluttered environment imposes significant challenges that raise critical issues related to surgical precision and safety. With the availability of robotic assisted MIS, existing research has explored the use of motion stabilisation to simplify the execution of delicate surgical tasks such as small vessel anastomosis [1]. Current work also suggests that global stabilisation of the soft tissue may not be necessary and local stabilization of the foveal field-of-view (FOV) is sufficient [2].…”

Abstract. The use of master-slave surgical robots for Minimally Invasive Surgery (MIS) has created a physical separation between the surgeon and the patient. Reconnecting the essential visuomotor sensory feedback is important for the safe practice of robotic assisted MIS procedures. This paper introduces a novel gaze contingent framework with real-time haptic feedback by transforming visual sensory information into physical constraints that can interact with the motor sensory channel. We demonstrate how motor tracking of deforming tissue can be made more effective and accurate through the concept of gazecontingent motor channelling. The method also uses 3D eye gaze to dynamically prescribe and update safety boundaries during robotic assisted MIS without prior knowledge of the soft-tissue morphology. Initial validation results on both simulated and robotic assisted phantom procedures demonstrate the potential clinical value of the technique.

“…In current surgical practices, it is common to use epicardial mechanical stabilizers to dampen the cardiac motion. However, the residual deformation may still be large enough to hinder tasks such as small vessel anastomosis [1] [2]. To overcome this problem, a number of techniques have been proposed for introducing virtual stabilisation to the surgical scene based on soft-tissue deformation tracking and image warping [3] [4][5] [6].…”

Abstract.With the increasing sophistication of surgical robots, the use of motion stabilisation for enhancing the performance of micro-surgical tasks is an actively pursued research topic. The use of mechanical stabilisation devices has certain advantages, in terms of both simplicity and consistency. The technique, however, can complicate the existing surgical workflow and interfere with an already crowded MIS operated cavity. With the advent of reliable vision-based real-time and in situ in vivo techniques on 3D-deformation recovery, current effort is being directed towards the use of optical based techniques for achieving adaptive motion stabilisation. The purpose of this paper is to assess the effect of virtual stabilization on foveal/parafoveal vision during robotic assisted MIS. Detailed psychovisual experiments have been performed. Results show that stabilisation of the whole visual field is not necessary and it is sufficient to perform accurate motion tracking and deformation compensation within a relatively small area that is directly under foveal vision. The results have also confirmed that under the current motion stabilisation regime, the deformation of the periphery does not affect the visual acuity and there is no indication of the deformation velocity of the periphery affecting foveal sensitivity. These findings are expected to have a direct implication on the future design of visual stabilisation methods for robotic assisted MIS.
