  • Patent number: 10082384
    Abstract: A detection device, such as a camera-enabled smart phone, may be used to take one or more pictures of an external fixation frame attached to a patient. The pictures may be transmitted to a computer system accessible by the patient's physician. The computer system may uniquely identify each strut of the external fixation frame and determine the length of each strut. The computer system may compare the determined length of each strut to a planned length of the struts for a particular time interval as outlined in a correction plan. If the struts are the correct length for the particular time interval, the fact may be indicated to the physician and transmitted to the patient. If the struts are not the correct length, the computer system may update the correction plan to account for the discrepancy plan, with the updated correction plan transmitted to the patient.

  • Patent number: 10010350
    Abstract: An adjustable length strut includes two joints, a threaded rod extending between the joints, and a tube adapted to receive the threaded rod. An actuation mechanism with gear teeth extending radially outward of the strut axis is rotatably fixed to the threaded rod. A protrusion may be coupled to an end of the threaded rod by a rotatable collar, with the protrusion extending through a slot in the tube to mark the length of the strut. A modular attachment member may be adapted to be couple to the first joint and include a worm gear adapted to engage gear teeth of the actuation mechanism. The modular attachment member may include a radiofrequency identity tag mechanism adapted to be read by a tag reader of a tool, the tool adapted to couple to the attachment member to rotate the worm gear to increase or decrease the effective length of the strut.

  • Patent number: 9987043
    Abstract: A tool for implementing a correction plan in an external fixation frame having a plurality of adjustment elements or screws, for example, generally includes a driver, a motor, a controller, and a processor. The driver is adapted to engage and rotate each of the screws. The motor is coupled the driver and adapted to rotate the driver. The controller is connected to the motor and configured to control operation of the motor. The controller may determine whether the tool is engaged with a strut and which strut is engaged, and may determine how much the strut has rotated, taking into account intentional or unintentional manual rotation of the tool. The tool may also include features to help ensure proper engagement between the drive and the strut. Variations may be provided in which similar functionality is provided with manual rotation of a motorless tool.

  • Patent number: 9888943
    Abstract: An external fixation clamp for receiving a fixation element includes an inner jaw and an outer jaw movable between an open position that permits the fixation element to be placed between the inner and outer jaws and a closed position that restricts removal of the fixation element from between the inner and outer jaws. A latch assembly may cooperate with the inner and outer jaws to secure the jaws in a closed position. The latch assembly may comprise a latch and a latch biasing member. The latch may be configured to translate linearly relative to one of the inner and outer jaws, and the latch biasing member may have a first higher level of stored energy when the inner and outer jaws are in the open position and a second lower level of stored energy when the inner and outer jaws are in the closed position.
