Exactech将Equinoxe无茎的肩部生产转移到基于激光的3D打印

医疗设备制造公司Exactechis transitioning the manufacturing process of its Equinoxe Stemless Shoulder to laser based additive manufacturing.

The Stemless Shoulder, a bone-conserving anatomic total shoulder prosthesis released in 2018, previously used electron beam melting (EBM) additive manufacturing. Prior to switching processes, Exactech是GE增材获得的ARCAM的客户,拥有专有EBM专利,2010年是最早获得FDA批准的人之一for an implant product made usingArcam’s EDM technology.

Now, the prosthesis will be made using laser-based additive manufacturing to create its porous bone cage.

“我们对我们最初的EBM无茎肩植入物以及我们从外科医生客户那里收到的早期积极临床反馈感到非常满意,” Exactech四肢副总裁Chris Roche说。“新的激光印刷设备建立在这一坚实的基础上,同时还使我们能够增加生产以服务于更多的患者,从而驱动我们并实现我们的任务。”

假体和3D打印

3D打印非常适用于植入物的创建,因为它们的设计可以定制并更改为患者及其目的。与通过常规方法相比,不仅如此,而且3D打印也可以为植入物提供改善的功能。

医疗添加剂制造领域的公司已经研究了几年来研究植入物雷电竞充值的各种潜在材料和方法。2017年,英国化学公司约翰逊·马特西(Johnson Matthey)identified the3D打印的潜力与贵金属to create anti-bacterial prosthesis.

A弗吉尼亚理工学院由助理教授布莱克·约翰逊(Blake Johnson)领导的团队released new research详细说明在人造肢体和佩戴者组织之间的交点上集成电子传感器的能力,以创建真正合适的假体。今年早些时候,研究人员在Paulista University(UNIP)在巴西圣保罗,实施了一种方法使用智能手机捕获数字面部印象颌面缺陷的患者中,数据用来创建具有成本效益的3D印刷面部假体的患者。

The Stemless Shoulder in use

位于俄亥俄州阿克伦的水晶诊所的柯蒂斯·诺埃尔(Curtis Noel)和密歇根州底特律的亨利·福特卫生系统的斯蒂芬妮·穆(Stephanie Muh)是上个月使用无茎肩进行手术的骨科医生。

According to Muh, the Stemless Shoulder is unique from other 3D printed prosthetics: “One of my favorite features of the Stemless implant is its bone cage structure that is designed to provide initial press-fit fixation while also allowing for bone-through growth. That intentional design element, along with the porous structure being designed to mimic the trabecular nature of cancellous bone, differentiates it from competitors.”

“As a member of the design team, I am very proud to be one of the first to implant the laser-printed Stemless Shoulder,” Noel added. “The bone conserving design, along with its compatibility to the Equinoxe Shoulder System, make this a great solution for both patients and surgeons.”

In addition to Noel, the design team responsible for the Stemless Shoulder includes Felix Savoie, MD,杜兰大学在新奥尔良;医学博士Pierre-Henri FlurinClinique du Sport在波尔多 - 米尔加纳克;医学博士Ryan Simovitch,HSS佛罗里达在西棕榈滩;医学博士托马斯·赖特(Thomas Wright)佛罗里达大学在盖恩斯维尔;和医学博士约瑟夫·扎克曼(Joseph Zuckerman)NYU Langone骨科医院在纽约市。

Exactech said it plans to transition all U.S Stemless Shoulder procedures to its laser-printed devices throughout the rest of this year.
