Development of a Virtual Training Simulator to Model Shoulder Replacement Surgery

在我们的老龄化人口中，上肢矫形手术的发生率急剧增加。尽管一些 目前采用的关节置换手术是成功的，大多数外科医生往往发现他们的技术 挑战性最近，人们对使用模拟器来训练外科工作人员的兴趣越来越大， 类似于飞机驾驶员所采取的方法。因此，合乎逻辑的假设是， 将通过在常规系统中实施虚拟模拟器， 培训课程。 为了解决这个问题，建议研究的主要目标是开发一个虚拟模拟器，作为一个可靠的培训 这是Schulich医学院和牙科学院参与肩关节置换手术的外科工作人员使用的工具 以及手部和上肢中心。为了提高开发的模拟器的质量和有效性， 将配备增强的触觉反馈，旨在为外科医生提供真实的截骨感觉 与关节盂表面处理程序相关的手术。 系统的准确性和可行性将通过广泛的实验测试来保证， 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术前计划 在给病人做手术之前从长远来看，据设想，开发的虚拟模拟器将提供 手术时间和翻修率的大幅减少，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.
