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

Abstract

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.

User experiences of virtual reality technologies for healthcare in learning: an integrative review

“…Quality was quantified by assigning a 0 (not mentioned or unclear) to 1 (mentioned) score per criterion question. The majority of the articles were rated as being of fair quality (Benham-Hutchins and Lall 2015;Chow 2012;Chow et al 2012;Koo et al 2015;Polivka et al 2019;Reznek, Rawn, and Krummel 2002;Süncksen et al 2018) to good quality (Awtrey et al 2015;Bracq et al 2019b;Butt, Kardong-Edgren, and Ellertson 2018;Chow 2016;Färber et al 2009;Girod et al 2016;Johannesson et al 2013;Kardong-Edgren et al 2019;Kidd, Knisley, and Morgan 2012;Kurenov et al 2017;Leung et al 2013;Nicolaidou et al 2015;Padilha et al 2018;Prasad et al 2018;Sankaranarayanan et al 2011;Schvartzman et al 2014;Schwaab et al 2011;Verkuyl, Betts, and Sivaramalingam 2019;Vottero 2014) (Table 1 in the Appendix). The main factors which impacted the quality scores related to the lack of clear inclusion or exclusion criteria or to the study setting having been poorly described.…”

“…All of the studies were published between 2002 and 2019 (Figure 2). The studies were conducted in the USA (Awtrey et al 2015;Benham-Hutchins and Lall 2015;Butt, Kardong-Edgren, and Ellertson 2018;Girod et al 2016;Kardong-Edgren et al 2019;Kidd, Knisley, and Morgan 2012;Koo et al 2015;Kurenov et al 2017;Polivka et al 2019;Reznek, Rawn, and Krummel 2002;Sankaranarayanan et al 2011;Schvartzman et al 2014;Schwaab et al 2011;Vottero 2014), Hongkong (Chow 2012(Chow , 2016Chow et al 2012), Canada (Leung et al 2013;Verkuyl, Betts, and Sivaramalingam 2019), Germany (Färber et al 2009;Süncksen et al 2018), France (Bracq et al 2019b), Sweden (Johannesson et al 2013), Greece (Nicolaidou et al 2015), Portugal (Padilha et al 2018) and India (Prasad et al 2018).…”

The Effect of Haptic Feedback on Efficiency and Safety During Preretinal Membrane Peeling Simulation

“…Since touch is the earliest sense developed during human embryology, haptic technology should not be underestimated for surgical specialties that rely on sensory input 11. Implementation of haptic technology into retina surgery is anticipated to improve efficiency and safety while reducing the training required to perform surgical procedures 8,15–17…”

Scissors-Type Haptic Device Using Magnetorheological Fluid Containing Iron Nanoparticles

“…Tactile feeling is useful for perceiving the physical properties of objects; however, existing surgical robots cannot display tactile information when surgical tools come in contact with living tissues [6][7][8]. Computer-assisted surgical systems combined with haptic interfaces demonstrated better user experience compared with the presently available common computer-aided design system [9].…”
