摘要： A haptic robotic system for reaming an acetabulum prior to inserting an acetabular cup is more accurate than conventional instruments and may reduce the risk of dislocation and improve durability of a hip implant. Disclosed is a three-dimensional tool path, referred to as a haptic volume. Once the haptic volume is implemented into the software of a haptically constrained surgical robotic system, the cutting tool or reamer can only be utilized within the haptic volume. The haptic volume guides the surgeon in preparing the final reamed bone surface with a greatly reduced chance of the reaming unintended bone and greatly increases the chance that the reaming procedure may be carried out using one reaming tool, or using a single-stage reaming process.

摘要： Provided are a bending structure and a joint function part, capable of stabilizing bending operation and simplifying a structure. In the bending structure, an inner coiled part 5 is located into an outer coiled part 3. The outer coiled part 3 has a plurality of gaps 3c distancing adjacent coils 3b in an axial direction, and coils 5b of the inner coiled part 5 are provided so as to correspond to the gaps 3c of the outer coiled part 3 and fit between the adjacent coils 3b of the outer coiled part 3 while being in contact with the adjacent coils 3b . A dimension P is set in a range meeting πR/4N≤P

摘要： A blade assembly (22, 210) for use with a sagittal saw assembly comprising a handpiece (24) having a forwardly directed front face and a drive assembly (30, 34, 48) disposed inside said handpiece (24) is described. The blade assembly (22, 210) comprises an elongate guide bar (110, 212) adapted to, when coupled to the handpiece, extend forwardly from the handpiece front face and terminate at a distally directed face spaced from the handpiece front face. The guide bar (110, 212) includes a bottom bar (116, 218), an inner bar (118, 220) and an outer bar (120, 222) that are stacked together. The inner bar (118, 220) holds the bottom bar (116, 218) and the outer bar (22) in spaced relationship from each other, and contributes to the overall rigidity of the guide bar (110, 212). A saw blade (112, 214, 302) is movably attached to said guide bar (110, 212) between the bottom and outer bars (218, 222). Said saw blade (112, 214, 302) has teeth (168, 308) which extend outwardly beyond said guide bar distally directed face, and said saw blade has a thickness dimension defined transversely to the elongated direction of said guide bar (110, 212). A connecting member (114, 216, 312) extends in the space between the bottom and outer bars (218, 222) and has a first end adapted to be connected to the drive assembly (30, 34, 48) of the sagittal saw. A second end of the connecting member is connected to said saw blade (112, 214, 302) such that said connecting member (114, 216, 312), when driven by the drive assembly (30, 34, 48), is adapted to displace said saw blade (112, 214, 302) so that said teeth (168, 308) oscillate back and forth across said guide bar distally directed face. Said guide bar (110, 212) has a thickness dimension defined transversely to the elongated direction thereof, said thickness dimension being no greater than the thickness dimension of said saw blade (112, 214, 302). Said connecting member (114, 216, 312) and said saw blade (112, 214, 302) comprise a monolithic, one-piece component.

摘要： The invention is directed to a single surgical saw that will drive both sheathed blade assemblies (108) as well as non-sheathed (standard) blades (200), and a sheathed blade (108) that prevents the potential contact between the moving interior blade and the exterior sheath (106). The surgical saw comprises a saw head (160) comprising a collet (162) with an opening configured to receive a movable blade (108; 200), wherein the blade is removably connected within the collet. A handpiece (166) is connected to the saw head, the handpiece having a drive mechanism. The drive mechanism is configured to move the blade.
