Embodiment Construction

[0038] According to the invention, the core drill can in particular be used for core drilling in a tubular bone 10 such as a femur. For this purpose, the core drill contains a drill bit 12 connected to a flexible shaft 14 . Rod 16 connects flexible shaft 14 to the chuck of a drill, such as a pneumatic drill. The core drill also contains a flushing unit 18 for flushing out drill cuttings present in the region of the drill head 12 with a flushing medium. In the medical field, the flushing medium is preferably a saline solution. In other technical fields, gas or other liquid media can be used as flushing medium.

[0039] The rinsing unit 18 contains a connection device 20 connected by a hose for storing the contained rinsing medium. The rinsing medium passes through a channel 24 of a guide element 22 provided in the rinsing head 18 . From the channel 24 , flushing medium is supplied into a cylindrical cavity 26 in the guide element 22 . From there, the flushing medium flows ...

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).

Description

technical field [0001] The present invention relates to devices for treating human and / or animal tissue, in particular arthroscopes, endoscopes or coring drills, especially drills for intramedullary reaming of long bones such as the femur. Background technique [0002] Arthroscopes are used to access human or animal joint cavities, for example to treat bone surfaces. The treatment may be a flat surface. Furthermore, arthroscopy may also be used to remove tissue, such as by grinding, scraping, etc., to remove portions of bone from a joint. Human tissue is treated in a similar manner with an endoscope; however, instead of being used in a joint cavity, the endoscope is used anywhere else in the human or animal body. [0003] When a long bone such as a femur is fractured, the two parts of the broken bone are aligned and a hole is drilled longitudinally. Nails are then inserted into the drilled holes to secure the two parts of the broken bone. [0004] The drill holes are for...
