Article
Background The accurate distal locking of intramedullary (IM) nails is a clinical challenge for surgeons. Although many navigation systems have been developed, a real-time guide method with free radiation exposure, better user convenience, and high cost performance has not been proposed. Methods This paper aims to develop an electromagnetic naviga...

The patient‐specific templates for osteotomy often have complex surface features. Using current commercial software to design such templates is quite complicated, tedious and unrepeatable. In this study, a novel surgical planning system for oral and maxillofacial surgery named EasyTemplate is developed, aiming to help doctors shorten the modeling t...

Background: Dental implant placement navigation systems based on optical tracking have been widely used in clinics. However, Electromagnetic (EM) navigation method that does not suffer from problems of hidden line-of-light has not yet been described. Methods: This work proposes an EM-guided navigation method named TianShu-ESNS with virtual calibra...

Zygomatic implant technology has been successfully applied to the repair of atrophic maxilla to avoid a large number of grafting surgery and shorten the recovery time. However, because of the long trajectories of zygomatic implant placement, the destruction of normal anatomical landmark and the narrow operating space, it is difficult to operate and...

PurposeRobot-world calibration, used to precisely determine the spatial relation between optical tracker and robot, is regarded as an essential step for optical-navigated surgical robot system to improve the surgical accuracy. However, these methods are complicated with numerous computation. Therefore, a more efficient method of a robot-world calib...
Article
Introduction: Various prefabricated maxillofacial implants are used in the clinical routine for the surgical treatment of patients. In addition to these prefabricated implants, customized CAD/CAM implants become increasingly important for a more precise replacement of damaged anatomical structures. This paper reviews the design and manufacturing of...
Article
The amount of supporting structure usage has been a major research topic in layer-based additive manufacturing (AM) over the past years as it leads to increased fabrication time and decreased surface quality. Previous studies focused on deformation and topology optimization to eliminate the number of support structures. However, during the actual f...
Article
Purpose Analyses of the morphology of proximal femora are essential for preoperative planning and designing customized femoral stems in total hip arthroplasty as well as intramedullary nailing fixation. Various studies reported measurements and analyses on the general geometry of proximal femora three-dimensionally. However, the modeling and measur...
Article
Introduction: Traditional medical training in oral and maxillofacial surgery may be limited by its low efficiency and high price due to the shortage of cadaver resources. With the combination of visual rendering and feedback force, surgery simulators become increasingly popular in hospitals and medical schools as an alternative to the traditional t...
Conference Paper
The haptic-based virtual reality simulation which can create a visual and tactile fusion in virtual environment for operators is an important application in surgical training. The catheter’s deformation and force feedback are key techniques in the catheter interventional simulator. The simulation of catheter interventional surgery is developed with...
