  • Patent number: 11806053
    Abstract: Vertebral retaining devices and instruments are provided. A retaining device may include a first monolithic body having a first handle and first jaw pivotably coupled to a second monolithic body having a second handle and a second jaw. The first body and the second body may be pivotably coupled to one another at an intermediate region between the respective handles and jaws. In some aspects, the first and second bodies may be polymeric. The first jaw and second jaw may be shaped to provide an access region between the first jaw and the second jaw when the retaining device is coupled to bone fasteners attached to the vertebrae. The retaining device may include a locking assembly coupled to the first handle and the second handle, and configured to retain the first jaw and the second jaw in a spaced relationship relative to one another.

  • Publication number: 20230285122
    Abstract: A transfer part for removable attachment and handling of a dental implant, the transfer part including a body portion having a longitudinal axis and including a traversing hole along the longitudinal axis, a center portion arranged in the traversing hole of the body portion, and a fastening mechanism for reversibly securing the transfer part to the dental implant, wherein the center portion and the body portion are configured for a relative motion between each other to switch from a first position to a second position and vice versa, wherein in the first position, the fastening mechanism is in a released state to allow a removal of the transfer part from the dental implant, and in the second position, the fastening mechanism is in an engaged state to allow a securing of the transfer part to the dental implant.

  • Patent number: 11446123
    Abstract: An instrument for holding and torque control tightening of a threaded implant device with an extender, the instrument including a frame forming a gripping handle and a holder, an elastic device that is arranged at the frame to provide a predefined elasticity to the frame, and a torque measurement device arranged on the frame, wherein the holder is configured to (i) removably hold the threaded implant device and to (ii) hold the extender for tightening the threaded implant device to an object after the threaded implant device has been removed from the holder, and the torque measurement device is configured to measure a torque applied to the threaded implant device via the extender by a deformation of the frame.

  • Patent number: 11173582
    Abstract: An instrument for torque controlled tightening of a threaded device, including a handle, an articulable head that is articulably connected to the handle, the articulable head including a drive ratchet configured to rotate relative to the articulable head and to engage with the threaded device or a tool for engaging with the threaded device, an elastic device arranged at the handle, and a pulling mechanism operatively connecting the articulable head with the handle, the pulling mechanism having a ratchet head mechanism to engage with the drive ratchet of the articulable head, and configured to engage with the elastic device at the handle such that the elastic device is compressed or expanded upon an application of a torque to the drive ratchet and simultaneously the ratchet head mechanism blocks the rotation of the drive ratchet.

  • Patent number: 10966802
    Abstract: A method for manufacturing an implant including the steps of providing an implant element, the implant element made of a non-metallic material, depositing a thin layer of titanium-based material directly over an outer surface of the implant element, and forming a titanium-based structural body in direct contact with the thin layer by three-dimensional (3D) printing, the structural body being thicker than the thin layer of titanium-based material.
