Abstract
The invention relates to a device for treating the human and/or animal body, for example a core drill, especially an intramedullary reamer for tubular bones, which has a drill head (12). Said drill head (12) is connected to a flexible shaft (14) which is in turn connected by a shank (16) to a drilling machine. The core drill also has a rinsing unit (18) by which means drilled material is removed in the area of the drill head (12). The rinsing unit (18) is connected to a rinsing channel (30) for this purpose, said rinsing channel being configured between the bore and the outside diameter of the flexible shaft (14). The drill head (12) has slits (34) which are connected to an inner cavity (36) of the drill head (12). Said cavity (36) is in turn connected to an inner channel (40) provided in the flexible shaft (14). The rinsing medium is guided into a rinsing head (42) through said inner channel. In the rinsing head (42), the rinsing medium enters a ring-shaped channel (58) through slits (60) provided in the flexible shaft (14). Said ring-shaped channel (58) is connected to a channel (54) to a which a suction device is connected by flexible tubing (56).
Claims (12)
1. A device for working human and/or animal tissue, in particular an ar-throscope, an endoscope or a core drill, in particular an intermedullary reamer for tubular bones, comprising - a flexible shaft (14) with an inner channel (40), - a working head (12) connected with the flexible shaft (14) and hav-ing openings (34) communicating with the inner channel (40), and - a washing unit (18) with a contact surface (64) for a substantially sealed application on an object (10), - the diameter (D) of the working head (12) being greater than the outer diameter (d) of the flexible shaft so that a washing channel (30) is formed by the outer surface of the flexible shaft (14) and a bore made in the object (10), the washing channel serving to pass a washing medium therethrough.
2. The device of claim 1, wherein the washing unit (18) is connected with a suction device for create a vacuum at the working head (12).
3. The device of claim 2, wherein the suction device is connected with the inner channel (40) of the shaft (14) so that the washing medium is sucked off through the inner channel (40) together with the remove material.
4. The device of one of claims 1-3, wherein the flexible shaft (14) has a plurality of articulately connected shaft segments (44) and a hose (50) is provided in the flexible shaft (14).
5. The device of one of claims 1-4, wherein the washing unit (18) com-prises a washing head (42) in which the flexibie shaft (14) is rotatably supported.
6. The device of claim 5, wherein the washing head (42) is supported for displacement in a guiding element (22) of the washings unit (18).
7. The device of one of claims 1-6, wherein the flexible shaft (14) has a plurality of shaft segments (44) with mutually engaging projections (46) and recesses (48) which engage behind each other in the longitu-dinal direction, leaving a gap around the shaft circumference, so that the shaft segments (44) are permanently connected in the longitudinal direction having mutual play.
8. The device of claim 7, wherein all projections (46) are of the same size and are distributed regularly over the circumference of the shaft (14).
9. The device of claim 7 or 8, wherein the gulp has a constant width in the circumferential direction.
10. The device of one of claims 7-9, wherein the ratio of gap width and shaft diameter (d) is between 1:100 and 1:10.
ii. The device of one of claims 1-10, wherein the flexible shaft (14) is connected to a tensioning device for stiffening the shaft.
12. The device of claim 11, wherein the flexible shaft (14) his an anchor-ing device for anchoring the shaft in the bone.
