Medical Devices and Medical Equipment Design QuikDrive Battery Powered Screwdriver by Peter Hess and Raimund Erdmann The battery powered screwdriver QuikDrive was developed for use in neuro-, craniomaxillofacial and hand surgery. This optimally balanced instrument with touch sensors for continuous, variable speed control enables the surgeon to insert and remove the smallest Stryker implant screws with a diameter of 1.2 to 2 mm. The reduced pencil-shaped form is tapered at the tip allowing the surgeon free vision within the operating area, freedom of movement and a very precise mode of operation in difficult applications.
