A surgical reamer driver provides a fully closed tube which prevents the invasion of debris and minimizes abrasion of soft tissue during use. The reamer device includes a minimum number of component assemblies, so as to permit easy replacement and minimize wear. The surgical reamer driver has four basic components, being: a housing assembly (10), a transmission drive train (21) enclosed in the housing assembly and having a surgical tool connector (4) at its distal end and a motor shaft coupling (11) at its proximal end, and a handle assembly (9), forming a driver which in a fully assembled state effectively prevents debris from access in the inner workings of the driver. A surgical kit comprises the surgical reamer driver and various surgical tools (227), and a case (221) for storing these. A method of disassembling the surgical reamer driver is also disclosed.L'invention concerne un système, un procédé et/ou un dispositif d'entraînement d'alésoir permettant d'obtenir un tube entièrement fermé qui empêche la pénétration de débris et limite au minimum l'abrasion des tissus mous pendant l'utilisation. L'alésoir comprend un nombre minimum d'ensembles de composants, pour permettre un remplacement aisé et réduire l'usure au minimum.
