A front end attachment for a powered surgical tool comprises a nose and an irrigation fitting. The nose extends forward from a proximal end of the nose. The nose defines a bore and an enclosed channel. The bore is for receiving a cutting accessory for movement therein. The enclosed channel extends longitudinally and helically along the nose such that, as the channel extends longitudinally, the channel curves around the nose so as to curve around the bore. The irrigation fitting is received by the enclosed channel in the nose.

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.

A surgical bone cutting device, including a handle configured to facilitate operation and control of said device by an operator, and an elongated hollow member extending from the handle, the hollow member having a proximal end and a distal end; wherein the hollow member includes an opening at the distal end thereof and a rotatable cutting element extending through the opening, and wherein the hollow member includes a first bend at the proximal end thereof, such that the part of the hollow member distal to the proximal bend is offset a central axis of the hand.

A front end attachment for a powered surgical tool. The front end attachment includes a nose. The nose defines a bore for receiving a shaft of a cutting accessory that is connectable to a motor of the powered surgical tool. The nose also defines a groove separate from the bore. The groove is formed in an outer surface of the nose and extends longitudinally along the nose. An irrigation fitting includes a tube that is seated in the groove of the nose. The irrigation fitting is adapted to receive an irrigating fluid. A heat shrink tubing is disposed over the outer surface of the nose to extend over and enclose the groove. The heat shrink tubing secures the irrigation fitting to the nose.

An ultrasonic osteotome bit, comprising a bit body (1), a bit bar (2) and a bit tip (3). One end of the bit bar (2) is connected to the bit tip (3), and the other end of the bit bar (2) is connected to the bit body (1). The bit tip (3) is of a prism or substantially prism structure with the cross section of a polygonal structure, and the bit tip (2) has at least two cutting faces of different cutting widths. The bit is provided with a liquid flow hole (41), and the bit tip (3) is provided with a knurled structure that extends from a foremost end face of the bit tip (3) towards the bit bar (2) to form a file-type bit. The ultrasonic osteotome bit not only meets the requirement of a surgeon for the accuracy of bone cutting width, but also saves the time required to replace bits of different widths, thereby improving the surgical efficiency.

Medical devices and related methods for transforming bone, other tissue, or other material are disclosed herein. According to an aspect, a cutting device includes a static casing having a width of substantially a first distance. The cutting device also includes a blade working body including a first end and a second end. The first end is configured to operatively connect to a source of movement.
