Methods and devices that displace bone or other hard tissue to create a cavity in the tissue. Where such methods and devices rely on a driving mechanism for providing moving of the device to form a profile that improves displacement of the tissue. These methods and devices also allow for creating a path or cavity in bone for insertion of bone cement or other filler to treat a fracture or other condition in the bone. The features relating to the methods and devices described herein can be applied in any region of bone or hard tissue where the tissue or bone is displaced to define a bore or cavity instead of being extracted from the body such as during a drilling or ablation procedure.

A surgical tool that includes a nose through which a cutting accessory extends. The nose is formed with an enclosed channel through which irrigating fluid is flowed. The enclosed channel has a helical shape such that as the channel extends longitudinally along the nose, the channel curves around the nose and the cutting accessory disposed in the nose.

A medical drill bit comprises an accommodating slot disposed concavely on a main body of the medical drill bit, a separate board disposed in the accommodating slot to separate the accommodating slot into a first slot and a second slot, and a lid engaging with the separate board and covering the accommodating slot. The lid and the separate board do not rotate with the main body when the main body in rotation. The accommodating uses to fill with cooling liquid which able to be pumped out from the accommodating slot, and fresh cooling liquid is able to inject into the accommodating slot for cooling the drill bit in rotation.

An orthopaedic tool cluster clamp includes a pair of jaws held together and defining a distance therebetween, the jaws being movable relative to one another to adjust the distance; a connector holding the jaws together, with actuation of the connector adjusting the distance between the jaws; a cam base including a ramped portion statically associated with one of the jaws; and a cam lever pivotally connected to the connector about an axis of rotation and held against the cam base. The cam lever defines a profile such that rotating the cam lever along the ramped portion and pivoting the cam lever about the axis of rotation both cause actuation of the connector.

A surgical drill type cutting tool includes a shank and an active portion extending in the extension of the shank, with chip areas extending along the active portion, and a ring surrounding a part of the active portion, an inner surface of the ring engaging the active portion without closing off the chip areas, allowing irrigation fluid to provides useful irrigation over most of the length of the active portion of the surgical drill bit.

Disclosed herein is a surgical device. The surgical device includes a cutting burr, a flexible/deflectable shaft, an elongated fluted shaft, a sheath, and an outer tube. The cutting burr has a fluted extension. The flexible/deflectable shaft has a distal end and a proximal end, the distal end is configured to be connectable to the fluted extension of the cutting burr. The elongated fluted shaft is configured to be connectable to the proximal end of the flexible shaft. The sheath is configured to receive all or portion of the flexible shaft and the elongated fluted shaft. The outer tube is configured to receive the sheath such that there is enough space for fluid irrigation between the outer tube and the sheath.

A surgical instrument includes a first member defining an axis and including a cutting surface. A second member includes a cutting surface that is rotatable relative to the first member. A third member includes an outer surface. The cutting surface of the second member is rotatable relative to the outer surface to transfer the cut tissue along the axis. Systems and methods are disclosed.

A rotary tool configured for high speed condensing and/or cutting action to form a hole. The tool has a body around which is formed a plurality of flutes. Each flute has a cutting face on one side and a densifying face on the other side. A land between adjacent flutes establishes a substantially margin-less working edge along each cutting face. The working edges are configured to produce osseodensification when the tool is operated in the condensing mode. A cavity is formed inside the body with access through its apical end. A plurality of spurs rim the apical end. Each spur has a grinding edge that is offset from said longitudinal axis in the cutting direction of rotation. Some of the flutes open directly into a gullet formed between adjacent spurs. Some of the flutes open directly into leading flanks that fall away from each grinding edge.

A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the images generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as at least partially transparent. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

An ultrasonic osteotome bit, comprising a bit bar (1), a bit body (3), and a bit grinding portion (2) located at a front end of the ultrasonic osteotome bit. The bit grinding portion (2) is in the shape of a triangular pyramid, the bottom face of the triangular pyramid is the rear end of the bit grinding portion (2), and the tip of the triangular pyramid directly facing the bottom face is the front end of the bit grinding portion (2). One end of the bit bar (1) is connected to the rear end of the bit grinding portion (2), and the other end of the bit bar (1) is connected to the bit body (3). Two of the three lateral pyramidal faces of the triangular pyramid are respectively used as a first grinding face (21A) and a second grinding face (21B). By means of the ultrasonic osteotome bit, a normal bone-grinding operation can be completed, and since the front end thereof is small in area, the grinding speed is high. In addition, owing to the design in which the front end is small while the rear end is large, a good visual field can be provided for a surgeon. Moreover, with the unique full V-shaped structures design, the surgeon can guarantee that bone grooves at a hinge side after grinding form fully closed V-shaped grooves at any operating angle, thereby reducing the area of an incision window, facilitating the use by a surgeon and improving the surgical efficiency.
