A medical device, a cooling-fluid/rinsing-fluid hose, and a method for using a medical device. The medical device includes a handpiece with an interior enclosed by a handpiece housing, preferably for receiving a drive. The medical device also has an effector arranged on or coupleable to the handpiece and a supply device for supplying cooling fluid and/or rinsing fluid to the effector. The supply device includes a guide tube or guide cannula that passes through the interior in the handpiece longitudinal direction and is rigidly connected to the handpiece. The guide tube or guide cannula, which opens to the outside in a distal and in a proximal handpiece region, longitudinally guides a preferably single-use cooling-fluid/rinsing-fluid hose that is pushed into the guide tube.

Medical device and cooling-fluid/rinsing-fluid hose

A keyless coupling for a tool shaft and a handpiece of a surgical instrument having a first coupling section, which is provided on a proximal section of the tool shaft, a second coupling section, which is provided on a distal section of a shaft holder of the handpiece, and a locking/unlocking element. The locking/unlocking element is arranged on the tool shaft and forms a latching section, and the shaft holder has an undercut for receiving the latching section in a locking position of the two coupling sections such that the latching section and the undercut are in latching engagement with one another and secure the two coupling sections against a relative axial movement with respect to one another at least in the pulling direction.

A saw blade of a bone saw machine includes a distally arranged or configured row of saw teeth and a proximally arranged or configured coupling region for coupling the saw blade with an oscillating rotating tool receptacle of the bone saw machine. The saw blade is designed with two counter-rotating curvatures or bends approximately in the manner of an S shape.
