This present invention relates to medical procedures and distraction devices for internal joint distraction.

A fixing tool is disclosed, which can help reduce a possibility that heat may be transferred to a user when a state is changed in a material of a member for fixing a predetermined site of a human body. The fixing tool has a deformation portion that is configured to be deformable, that at least partially covers an outer periphery of any site of a limb, a trunk, a neck, and a head, and that is deformed to align with the site through the deformation, and a heat insulating material that is disposed in a portion corresponding to at least the site on an outside surface of the deformation portion.

Internal fixation systems and methods for prone lateral spine surgery on a patient. The system comprises a lateral lumbar interbody fusion (LLIF) retractor and a posterior compressor/distractor including a posterior distractor rack assembly having a rack and a posterior distractor carriage assembly configured to operably engage the posterior distractor rack assembly. The posterior distractor rack assembly includes a first swivel tube subassembly having a first swivel tube, and the posterior distractor carriage assembly includes a second swivel tube subassembly having a second swivel tube. The first and second swivel tubes are each configured to receive a pedicle screw and screw tower therein. The first and second swivel tube subassemblies are configured to be moved and positioned with respect to each other, such that a surgeon can access the patient's disc space from the left and right sides, and without the need for a bolster.

A foot holding assembly for securing a foot of a patient during a surgical or diagnostic procedure includes a boot configured to hold the foot of the patient. In addition the assembly includes a rigid sole coupled to the boot. Further, the assembly includes a pivot arm having a first end rotatably coupled to the sole with a rotatable coupling configured to allow the sole to rotate relative to the first end of the pivot arm about an axis oriented perpendicular to the sole. The rotatable coupling includes an incremental locking mechanism including a locked position and an unlocked position. When the incremental locking mechanism is in the locked position, the rotational position of the sole about the axis is releasably locked. When the incremental locking mechanism is in the unlocked position, the sole is free to rotate relative the first end of the pivot arm only about the axis.

A system and method for securing a patient's leg during a medical or diagnostic procedure having a rail assembly including a first rail pivotally coupled to a second rail, a slider block, a pivot arm, and a sole assembly with a boot to restrain and support the patient's foot.

A long-bone fracture-reduction robot is provided, and includes a machine base; a support slidably connected onto the machine base and able to move up and down; a plurality of electro-hydraulic drivers; and a six-degrees-of-freedom parallel robot arranged on the support, with the motion of the robot in six degrees of freedom hydraulically controllable using the plurality of electro-hydraulic drivers. The long-bone fracture-reduction robot includes two long-bone-fixing frames, one frame being coupled to the support and other being coupled to the six-degree-of-freedom parallel robot. The two long-bone-fixing frames are arranged to be side by side. Each of the two long-bone-fixing frames is fixedly connected to a corresponding mounting-and fixing plate.

This present invention relates to medical procedures and distraction devices for internal joint distraction.

The skull clamp system with pressure limiting and alarm systems includes at least one and preferably multiple inwardly power driven immobilizing pins adjustably engaging the skull of a patient. The pin power drive systems includes at least one sensor capable of sensing the degree of back pressure on the pin from contact of the pin against the bone of the patient, the sensor being capable of signaling the drive system to stop when the sensor detects a preselected degree of back pressure. The sensor is also capable of signaling an alarm to warn of any reduction of pressure applied to the pins that might result from pin slippage.

Systems and methods include stabilizing a leg and providing femoral distraction during a knee arthroplasty surgery. The disclosed systems include a leg holder to receive a foot of a patient and a femoral distractor received in the leg holder and disposed underneath a knee of the patient. The femoral distractor is actuated to increase or decrease in length to distract the femur such that a surgeon may cut to resection the femur without also simultaneously providing distraction of the femur.

The present application provides external bone fixation systems. The systems include one or more pairs of bone fixation platforms in the form of rings or partial rings. The platforms may be coupled to corresponding bone segments. The pair of platforms are configured to accept a plurality of struts extending therebetween. The struts are configured to attach to the platforms via joints that provide three degrees of rotation. The struts are also configured such that their longitudinal length extending between the joints/platforms can be incrementally adjusted while attached to the platforms. The struts are further configured such that their total range of length adjustment can be increased by coupling at least one add-on component to the struts in situ. The lengths of each of the plurality of struts may be adjusted to arrange the platforms, and thereby the bone segment coupled thereto, in particular relative positions and orientations.
