Definitions
- the invention relates to a device for external fixation of broken bones according to the preamble of claim 1.
- a device of this type is known from DE 19746687 AI.
- This known device is disadvantageous in that the balls and ball sockets of the ball joints are designed with a smooth surface, with the result that excessively high locking forces have to be applied to determine the relative positions of the links if the fixing device is to be really stiff even under load.
- the object of the invention is therefore to improve a device of the type mentioned in the introduction so that it has better dimensional stability in the fixed state.
- FIG. 1 shows the fixing device according to the invention attached to a finger
- Fig. 2 (a) - (d) a link of the fixing device according to the invention in a view from the side, from behind, from above and in perspective, and
- Fig. 1 shows the device for external fixation of broken bones attached to a finger.
- the devices device has a multi-bar with links 1, as shown in FIGS. 2 and 3.
- links 1 as shown in FIGS. 2 and 3.
- those are provided which carry a bone nail 9.
- the members 1 Apart from the end members, the members 1 have a ball 2 at one end and a ball socket 3 at the other end.
- the ball socket 3, and thus also the ball 2 extends geometrically over more than one hemisphere, so that joined links do not easily separate from one another. Links are joined together with elastic deformation of the ball socket, which is facilitated by slots 4.
- the relative position of adjacent links 1 is determined with the aid of clamping brackets 6 which surround the ball socket on the outside, by means of which, in the tensioned state, the ball socket 3 is pressed against the ball 2 of the adjacent link which surrounds the ball socket.
- the surfaces of ball 2 and ball socket 3 are provided with a surface roughening.
- This roughening can be achieved in the case of metal parts, that is to say in the case of a ball and ball socket made of metal or in any case with a metal surface, by die sinking erosion.
- a similar surface structure can be achieved with plastic ball and ball socket by EDM the surface of the mold in which these parts are cast, at least in the parts that determine the ball and ball socket. The roughness of the mold surface obtained in this way is then reflected on the product cast in the mold.
- Another possibility for obtaining the surface roughness is knurling the ball and ball socket.
