“…The compliance of an object is an estimate of its elasticity (Bergmann Tiest & Kappers, 2009). Zhou et al (2012) discovered that the reduced tactile feedback experienced in laparoscopic surgery reduces the surgeon's ability to discriminate the compliance of tissue.…”

This paper describes a psychophysical experiment which investigates the effect of the source of vision on the perception of compliance with a specific focus on palpation; a basic surgical task. Twelve participants were asked to complete four forced-choice compliance discrimination tasks representing different modes of surgery when assessing soft human tissue. These tasks were compliance discrimination using direct vision; indirect vision on a computer monitor; only haptic information; and only indirect visual information. In the first 3 tasks, the subjects actively indented pairs of silicone stimuli covering a range of compliances simulating soft human tissue using a tool and were asked to choose which stimulus within each pair felt harder. In the fourth task, participants watched video recordings of the stimuli being indented on a monitor without touching the stimuli themselves. As a control task, participants performed discriminations using their index finger without any visual cues present. The results were used to determine psychometric functions of group behaviour for all conditions. These functions suggest that participants performed best during the control task followed by that involving a combination of touch using tool and direct vision. The latter task presented higher compliance discriminability than the three remaining tasks. Moreover, the task using only indirect vision without any haptic information presented similar compliance discriminability to that using only touch through a tool without any visual information. We conclude that while compliance discrimination via a tool is achievable under direct visual conditions, it remains significantly more challenging than through direct cutaneous information. The research shows the importance of visual cues for the discrimination of compliance as well as a cross-modal integration of visual and haptic sensory information in compliance discrimination, with key implications for the development of new surgical tools and training systems.--

“…Moreover, combined hapticvisual training modes have an advantage over either haptic or visual modes alone for tasks that have a force component, such as surgical simulation [15]. However, limitations to surgical training with a haptic feedback simulator were reported in one study; even though haptic feedback enabled a significant improvement in a laparoscopic suturing and knot-tying task with a higher learning rate, the surgeons reached a plateau after 5 h of training with the haptic device [16]. Recent work by Olsson et al reported an immersive virtual environment setup with a colocated visuohaptic display and head-tracking capabilities [17].…”

Haptic feedback improves surgeons’ user experience and fracture reduction in facial trauma simulation

Abstract-Computer-assisted surgical (CAS) planning tools are available for craniofacial surgery but are usually based on computer-aided design (CAD) tools that lack the ability to detect the collision of virtual objects (i.e., fractured bone segments). We developed a CAS system featuring a sense of touch (haptic) that enables surgeons to physically interact with individual, patient-specific anatomy and immerse in a threedimensional virtual environment. In this study, we evaluated initial user experience with our novel system compared to an existing CAD system. Ten surgery resident trainees received a brief verbal introduction to both the haptic and CAD systems. Users simulated mandibular fracture reduction in three clinical cases within a 15 min time limit for each system and completed a questionnaire to assess their subjective experience. We compared standard landmarks and linear and angular measurements between the simulated results and the actual surgical outcome and found that haptic simulation results were not significantly different from actual postoperative outcomes. In contrast, CAD results significantly differed from both the haptic simulation and actual postoperative results. In addition to enabling a more accurate fracture repair, the haptic system provided a better user experience than the CAD system in terms of intuitiveness and self-reported quality of repair.

“…This hesitation was caused, at least partially, by technical reasons: in early surgical robotic systems, haptic feedback was either patched on or estimated/simulated, the performance of which was rather limited, hence surgeons were less in favor of the outcomes [48]. However, with the fast developments in robotic technology, recent surgical systems with haptic feedback are equipped with new force sensors and very well implemented control [52,53], and as a result, more and more studies showed that haptic feedback became one of the most wanted features for the next generation of surgical robots [54][55][56][57][58][59].…”

The chronicle of surgical robots is short but remarkable. Within 20 years since the regulatory approval of the irst surgical robot, more than 3,000 units were installed worldwide, and more than half a million robotic surgical procedures were carried out in the past year alone. The exceptionally high speeds of market penetration and expansion to new surgical areas had raised technical, clinical, and ethical concerns. However, from a technological perspective, surgical robots today are far from perfect, with a list of improvements expected for the next-generation systems. On the other hand, robotic technologies are lourishing at ever-faster paces. Without the inherent conservation and safety requirements in medicine, general robotic research could be substantially more agile and explorative. As a result, various technical innovations in robotics developed in recent years could potentially be grafted into surgical applications and ignite the next major advancement in robotic surgery. In this article, the current generation of surgical robots is reviewed from a technological point of view, including three of possibly the most debated technical topics in surgical robotics: vision, haptics, and accessibility. Further to that, several emerging robotic technologies are highlighted for their potential applications in next-generation robotic surgery.
