Development of a Virtual Training Simulator to Model Shoulder Replacement Surgery

在我们老龄化的人口中，上肢矫形手术的发生率正在急剧增加。尽管有些人 在目前使用的关节置换手术中，大多数外科医生倾向于从技术上找到它们 很有挑战性。最近，人们对使用模拟器培训外科工作人员的兴趣越来越大，这种方式是 类似于对飞机飞行员采取的方法。因此，假设联合行动的长期结果是合乎逻辑的 更换程序将通过将虚拟模拟器实施为常规程序而大大增强 培训课程。 为了解决这一问题，拟议研究的主要目标是开发一个虚拟模拟器，用作可靠的培训 舒利希医学院和牙科参与肩关节置换手术的外科工作人员使用的工具 以及手和上肢中心。为了提高开发的模拟器的质量和效率，该系统 将配备增强的触觉反馈，旨在为外科医生提供逼真的去骨感觉 与关节窝表面处理相关的手术。 通过广泛的实验测试，保证了所开发系统的准确性和可行性 验证阶段。此外，外科医生将使用模拟器来磨练他们的技能并执行手术前计划 在给病人做手术之前。从长远来看，开发的虚拟模拟器将提供 大幅减少程序时间和修改率，这最终将转化为显著的成本节约 加拿大人。

The incidence of orthopaedic procedures of the upper limb is increasing dramatically in our aging population. Although some of the currently employed joint replacement procedures are successful, most surgeons tend to find them technically challenging. Recently, there has been growing interest in the use of simulators to train surgical staff, in a manner that is similar to the approaches taken for airplane pilots. As such, it is logical to postulate that the long term outcome of the joint replacement procedures will be significantly enhanced through the implementation of virtual simulators into the regular training curriculum. To address this, the primary goal of the proposed research is to develop a virtual simulator to be used as a reliable training tool by the surgical staff involved with shoulder joint replacement procedures at Schulich School of Medicine and Dentistry as well as Hand and Upper Limb Centre. To enhance the quality and effectiveness of the developed simulator, the system will be equipped with augmented haptic feedback, aiming to provide surgeons with a realistic feel on the bone removal operation associated with glenoid surfacing procedure. The accuracy and feasibility of the developed system will be ensured through an extensive experimental testing and validation phases. Furthermore, surgeons will use the simulator to hone their skills and perform pre-operative planning before operating on patients. Over the longer term, it is envisioned that the developed virtual simulator will provide substantial reductions in procedure time and revision rates, which will ultimately translate into significant cost savings to Canadians.
