Development of a Virtual Training Simulator to Model Shoulder Replacement Surgery

在老龄化人口中，上肢骨科手术的发生率急剧增加。虽然有些 目前采用的关节置换手术中的 % 是成功的，大多数外科医生倾向于在技术上发现它们 具有挑战性。最近，人们对使用模拟器来培训外科手术人员越来越感兴趣，其方式是 类似于飞机飞行员采取的方法。因此，假设联合的长期结果是合乎逻辑的 通过在常规系统中实施虚拟模拟器，更换程序将得到显着增强。 培训课程。 为了解决这个问题，拟议研究的主要目标是开发一个虚拟模拟器，用作可靠的训练 舒立克医学和牙科学院参与肩关节置换手术的外科手术人员使用的工具 以及手和上肢中心。为了提高所开发模拟器的质量和有效性，该系统 将配备增强触觉反馈，旨在为外科医生提供真实的去骨感觉 与关节盂表面处理程序相关的操作。 所开发系统的准确性和可行性将通过大量的实验测试和验证来确保 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进行术前计划 在对患者进行手术之前。从长远来看，预计开发的虚拟模拟器将提供 程序时间和修改率的大幅减少，这最终将转化为显着的成本节省 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.
