<p>A removable coupling system (10) for motor operated surgical tools. A removable coupling system for motorised surgical tools is presented, these being of the type comprised of two complementary coupling items: a motor shaft (20) and a tool head (2). The motor shaft and the tool head are linked together by an intermediate coupling rod (1), this being coupled at one end to the motor shaft, and receiving the coupling of the tool head at the other, the intermediate rod and the tool head being provided, at their coupling ends, with corresponding mutual fitting items, constituted of a male (3) and a female (4) section respectively, which when fitted together are adjustedly coupled together, with no possibility of rotation between the two, and in that it comprises an elastic means (6) complementary to a retaining means (7) integrated respectively in the intermediate rod and in the tool head, or vice versa, in such a way that during the coupling operation the elastic means is press-fitted into the retaining means until it reaches a final coupled position in which the retaining means presents resistance to the axial separation of the two sections.</p> |
