“…Hence, operators can still acquire realistic experience of making incisions on facial skin through this system. Tactile feedback was proved to be meaningful for operators to practice skills and improve their performance [ 13 , 30 ]. In most of proposed virtual surgical systems, haptic feedback was not realized or haptic rendering was not authentic for the reasons that interaction between surgical instruments and bio-tissue has not been studied too much and real deformation and experimental force data are insufficient.…”

“…In recent years, a series of virtual surgical systems have been developed to simulate maxillofacial surgery. Most of them targeted to bone operations such as drilling on the jaws [ 5 – 7 ], sawing or osteotomy in orthognathic surgery [ 6 – 8 ], moving bone segments [ 9 – 11 ], mandibular angle reduction [ 12 , 13 ], dental implant surgery (stepwise drilling) [ 14 ], bone fractures reduction [ 15 ] and bone defects reconstruction [ 16 ]. Few virtual surgical systems were incorporated with facial soft tissue models or were developed specially for soft tissue surgery [ 17 , 18 ].…”

Purpose Lack of biomechanical force model of soft tissue hinders the development of virtual surgical simulation in maxillofacial surgery. In this study, a physical model of facial soft tissue based on real biomechanical parameters was constructed, and a haptics-enabled virtual surgical system was developed to simulate incision-making process on facial soft tissue and to help maxillofacial surgery training. Methods CT data of a 25-year-old female patient were imported into Mimics software to reconstruct 3D models of maxillofacial soft and skeletal tissues. 3dMD stereo-photo of the patient was fused on facial surface to include texture information. Insertion and cutting parameters of facial soft tissue measured on fresh cadavers were integrated, and a maxillofacial biomechanical force model was established. Rapid deformation and force feedback were realized through localized deformation algorithm and axis aligned bounding box (AABB)-based collision detection. The virtual model was validated quantitatively and qualitatively. Results A patient-specific physical model composed of skeletal and facial soft tissue was constructed and embedded in the virtual surgical system. Insertion and cutting in different regions of facial soft tissue were simulated using omega 6, and real-time feedback force was recorded. The feedback force was consistent with acquired force data of experiments conducted on tissue specimen. Real-time graphic and haptic feedback were realized. The mean score of the system performance was 3.71 given by surgeons in evaluation questionnaires. Conclusion The maxillofacial physical model enabled operators to simulate insertion and cutting on facial soft tissue with realization of realistic deformation and haptic feedback. The combination of localized deformation algorithm and AABB-based collision detection improved computational efficiency. The proposed virtual surgical system demonstrated excellent performance in simulation and training of incision-making process.

“…The sawing procedure should minimize force and temperature rise to avoid or alleviate interference with the surgeon and the incidence of complications. Therefore, high-precision models of the sawing force and sawing temperature are becoming increasingly important for VR surgical training and surgical simulations [1][2][3].…”

Bone sawing is one of the most common operations during traditional dental and cranio-maxillofacial surgery and training systems based on virtual reality technology. It is necessary to predict and update conditions (including the sawing force, temperature and tool wear) in real time during VR surgical training and surgical simulation. All the specimens used in this study were fresh bovine scapula. The forces and temperatures were measured during the sawing process. Additionally, the thermal conductivity was measured via a laser flash instrument. Response surface methodology (RSM) was adopted to analyze and model the sawing force and sawing temperature. Meanwhile, tool wear was observed using a scanning electron microscope. The regression models of the sawing force and temperature rise under different experimental conditions were acquired. To obtain the minimum force within the recommended parameter ranges of commonly used medical reference parameters for bone sawing, a higher rotational speed combined with a lower feed rate were recommended. When considering the sawing force and temperature rise comprehensively, the rotational speed should not be extremely high (about 13,000 rpm is recommended). Meanwhile, abrasive wear is the main wear mode of saw blades. In order to avoid surgery failure, it is necessary to replace the saw blade in time. The experimental data were confirmed to be scientific and accurate for the predicted models of sawing conditions. To minimize the main cutting force, a feed rate of 40 mm/min combined with a rotational speed of 13,700 rpm is recommended. High cutting temperatures have the potential to cause irreversible tissue damage, so surgeons using dental reciprocating saws need to avoid excessively high-speed gears.
