Requirements and design specifications

During operations of removal of the femoral head and subsequent replacement, the leg is subjected to a series of movements to expose part of the bone. Normally, a manual device is used for this purpose, or a nurse takes charge of moving the leg. The project is the result of the customer’s willingness to automate the manual device in order to:

• free nurses from a strenuous activity;
• allow the surgeon to manage the limb movements autonomously;
• limit the forces applied to the limb;
• monitor the operation parameters (applied forces, imposed movements);
• configure the device according to the patient.

Performed activities

• Global support, from concept to prototype:
  – Concept
  – Detailed Design
  – Realisation (mechanics, electrical system, assembly, start)
  – Development of control system software
  – HMI development
  – Test
• Optimisation on the basis of the comments received and production of the pre-series.
