| 摘要 |
The invention relates to a device for connecting surgical clearing or drilling tools with a shaft, comprising the following: A) a shaft (1) with a central axis (2) and a front end (3); and B) a hollow body (5) comprising a first end (6), a second end (7), a wall (8) and a hollow space (4) which is coaxial to the central axis (2). The shaft (1) is guided into the hollow space (4) coaxially from the first end (6), with its front end (3), while the hollow body (5) can be or is connected to an implant or instrument component with its second end (7). After the shaft (1) has been guided coaxially into the hollow space (4) from the first, shaft-side end (6) of the hollow body with its front, drill head-side end (3), a stamping tool (not included in the drawing) is used to plastically deform the wall (8) of the hollow body (5) in such a way as to produce four impressions (10), each with a projection (11) in the hollow space (4). The projections (11) cause the shaft (1) to become deformed on the periphery in accordance with the projections (11), so that a form-fit fixture is created coaxially to the central axis (2) in terms of rotation about the central axis (2) and displacement between the shaft (1) and the hollow body (5). |
