Company Name:
ECMC Outpatient Rehabilitation
Company Background:
The Erie County Medical Center includes an advanced academic medical center with 602 inpatient beds, on-and off-campus health centers, more than 30 outpatient specialty care services and Terrace View, a 390-bed long-term care facility. ECMC is the regional center for trauma, burn care, behavioral health services, transplantation, and rehabilitation and is a major teaching facility for the University at Buffalo. Our amputee program includes pre-prosthetic training, prosthetic prescription, and prosthetic training. The prosthetic team includes a rehabilitation medicine physician, prosthetist, and physical therapist who meet regularly to evaluate patients and make recommendations.

Project Details

  1. Project Title: Rapid Design of a Pre-prosthetic for Upper Extremity Amputee
  2. Project Background
    The design and final configuration of a permanent prosthetic typically takes multiple months (up to a year) to be finalized. In the meantime, it is critical for patients to rehab using a “pre-prosthetic” device as soon as possible. Rehab includes the ability to perform basic functions like, eating with a fork and spoon, brushing teeth, baking and performing a variety of exercises using weights. In addition to recent amputation patients, there are increasingly individuals seen at ECMC that have been without a prosthetic for months or years. The ability to provide an inexpensive pre-prosthetic to rehab or retrain is an important capability that ECMC does not have the ability to provide. There is an amputee who is seen at ECMC with an upper extremity amputation, and for whom a prosthetic has been designed but not built.
  3. Project Objective
    The objective of this project is to rapidly build a pre-prosthetic for a patient who has an upper-extremity amputation. The design can be pictured below, however the prosthetic has not been built or tested yet. The prosthetic must be able to provide the following features: • An adjustable cuff that provides a sufficient holding force • An elbow joint that is easy to loosen/tighten and holds without slipping during activities that include lifting up to fifty pounds • A joint which provides functionality/motion similar to a wrist joint, but can be locked into position for each activity • End-effector(s) that support various activities, like: using fork/spoon, brushing teeth, holding weights, squeezing a ball between both hands/arms.
  4. Expected Deliverables
    The expected short term deliverable is the modeling and fabrication of a pre-prosthetic, inclusive of CAD models, basic analysis, technical documentation and fabrication of the device. The final design documentation must be developed in accordance with the standard represented in the design catalog []. All design documentation will be uploaded to the catalog for future use and additional development.
  5. Tentative Timeline
    The total time is about 10 weeks, this should include the following tentative breakdown: 2-3 weeks: generate CAD models, manufacturing instructions, and a bill of materials. 2-3 weeks: create the prototype and present it to ECMC. 3-4 weeks: iterate and
