Hinged fixation devices for combined upper jaw correction
Instrumentation and methods are provided for upper jaw correction surgery. The application discloses an orthopedic system and method that can be used to perform both a first distraction (for example a maxillary distraction) and a second distraction (for example a maxillary expansion) within the same surgical procedure. The instrumentation for separating first and second bone segments can include a first footplate; a second footplate; an actuator arranged to vary a distance between the first and second footplates; and a hinge that rotatably attaches the first and second footplates such that the first and second footplates can be angularly adjusted relative to each other about a pivot axis. Additionally, instrumentation and methods are provided for a hinged fixation device capable of securing and adjusting both the linear separation and angular orientation of bone structures.
Fixation Clamp
A fixation clamp for use in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements has at least one clamping assembly having a pair of jaws with at least two different size grooves to accommodate a bone fixation element such as a pin or rod. An alternate clamping assembly has at least three grooves wherein at least two of the grooves have a different size adapted to accommodate a correspondingly sized bone fixation element such as a bone pin. The longitudinal axes of the grooves define a polygon. The jaw pairs can be rotated about a central longitudinal axis to present different size reception cavities towards the pins or rocks depending on their diameter.
Distractor with bidirectional rotation control
A distractor, such as a pediatric mandibular distractor, includes a housing member elongated along a longitudinal axis. At least one distal footplate is attached to the housing member. A drive rod and at least one proximal footplate configured to be driven by the drive rod are provided. A housing engaging member is configured to engage a drive rod engaging member to prevent the housing from being rotated in either a first or second direction of rotation relative to the drive rod when a rotational force less than a predetermined force is applied to the housing or drive rod. The drive rod can be rotated relative to the housing in either the first or second rotational direction when a force greater than the predetermined force is applied to the drive rod or the housing.

Bioresorbable Inflatable Devices, Incision Tool And Methods For Tissue Expansion And Tissue Regeneration
Bioresorbable inflatable devices and tunnel incision tool and methods for treating and enlarging a tissue or an organ or a tube or a vessel or a cavity. The device is composed of a hollow expanding pouch made of a resorbable material that can be attached to a filling element. The pouch can be filled with a biocompatible materials, one or more times in few days interval, after the insertion of the device. While filling the pouch every few days the tissue expands and the filling material if it is bioactive start to function. The tunnel incision tool composed of a little blade that emerges from the surface of the tool in order to make shallow incisions in the surrounding tissue therefore enabling easy expansion of the tissue. This device and method can be used for example for: horizontal and vertical bone augmentation in the jaws and the tunnel incision tool is used to make shallow incisions in the periosteum when using the tunnel technique, sinus augmentation when the device is placed beneath the Schneiderian tissue, vessels widening if the pouch become a stent etc.
Implant for bone distraction
An implant includes an implant body and a distraction membrane. The distraction membrane is connected to the implant by a connection element. The connection element is arranged movably at least over a portion of a longitudinal axis of the implant body such that the distraction membrane is slidable along at least a portion of the longitudinal axis of the implant body.
Cantilever protraction device
The present invention provides body anchored protraction devices. The protraction devices direct the negative forces of protraction over a large surface area on the chest and abdomen of a patient. The protraction devices employ a cantilever support rod and ultra-low friction joints to enable low compression on the head without restricting free movement.
Curved alveolar bone distractor
The curved alveolar bone distractor includes an elongate curved and threaded traction rod supported on opposite ends by anchor brackets. The anchor brackets fix the traction rod onto bony foundation of a patient's jaw. Endcaps cap opposing ends of the traction rod to prevent dislodging and define the extent of working length of the traction rod. A traction bracket freely slides along the traction rod, and the traction bracket is fixed to a movable bony segment. A translator nut is threaded onto the traction rod to abut against a side of the traction bracket. Selective rotation of the translator nut pushes the traction bracket to move the movable bony segment a predetermined distraction distance. When assembled and installed, the working components of the curved distractor are exposed in the oral cavity to the facial side for easy access. Tools are provided to operate the translator nut.
