Cutting device for pediatric orthopedic nails

Pega Medical是一家致力于儿科骨科的医疗器械制造商。Pega Medical的两款产品是Fassier-Duval望远镜IM系统(FD)和简单锁定髓内系统(SLIM)，这两种系统分别是用于矫正畸形的自我延伸杆和用于在长骨中实现稳定固定的销。在手术中，由于每个患者的解剖结构不同，植入物被切割成不同的长度，以获得尽可能好的配合。目前，在植入FD时，术中女性假体被金刚石涂层的切割盘切割，并用去毛刺工具去毛刺。用专门设计的切割器原位切割男性种植体。在SILM的情况下，医院提供了不同长度和直径的植入物，外科医生在手术中使用原样。为了覆盖所有病例，这种方法需要外科医生为每次介入订购和准备多套植入物，从而增加了介入的成本。为了消除在每次手术中都有许多长度的植入物的需要，标准长度的植入物可以与切割设备一起使用。本项目从该切割装置的构思出发，分三个主要阶段进行，即设计与制造、测试与验证和装置制造准备。该项目将带来的好处是减少了固定系统的成本，而且还节省了干预期间的时间，并简化了库存管理。此外，PEGA将受益于我们的专业知识，PIS实验室将受益于行业合作伙伴关系。

Pega Medical is a medical devices manufacturer dedicated to pediatric orthopaedics. Two of Pega Medical'sproducts are the Fassier-Duval Telescopic IM System (FD) and the Simple Locking IntraMedullary System(SLIM) which are a self-extending rod designed to correct deformities and a pin designed to create a stablefixation in long bones respectively. During surgery, as the anatomy of every patient differs, the implants are cutat various lengths to get the best fits as possible.Currently, when implanting the FD, the female component is cut intra-operatively with a diamond-coatedcutting disc and de-burred with a de-burring tool. The male implant is cut in-situ with a specially designedcutter. In the case of the SLIM, the hospitals are provided with implants of different lengths and diameters thatsurgeons use as-is in surgery. In order to cover all the cases, this method requires surgeons to have many sets ofimplant ordered and prepared for every intervention and therefore increases the cost of the interventions.To eliminate the need to have many lengths available during every surgery, a standard length implant could beused along with a cutting device. This project consists in the conception of this cutting device and will berealized through three main phases that are the design and fabrication, the testing and validation and thepreparation for manufacturing the device. The benefits that this project will bring are the cost reductions forthe fixation system, but also for the time saved during the interventions and for the simpler inventorymanagement. Moreover, Pega will benefit of our expertise and the PIs lab will benefit of an industrialpartnership.
