A reduction device correction system for spinal surgery comprising two uniplanar clamps; a reduction rod having opposite pitch threaded ends, the reduction rod configured to be attached to each of the two uniplanar clamps; a stabilizing rod configured to be attached to each of the two uniplanar clamps; two provisional spine rods, each configured to be attached to a respective uniplanar clamp; and an adjustable force compression device comprising a constant force cable, the constant force cable configured to be attached to each of the two uniplanar clamps.

An imageless robotized device for guiding surgical tools to improve the performance of surgical tasks is provided. The method of using the robotized device may include the steps of: collecting anatomical landmarks with a robot arm; combining landmarks data with geometric planning parameters to generate a position data; and automatically positioning a guiding tool mounted to the robot arm. Particular embodiments for a limb fixation device are also described.

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 that includes a boot configured to hold the foot of the patient, a rigid sole coupled to the boot, a pivot arm having a first end rotatably coupled to the sole, a slider block pivotally coupled to a second end of the pivot arm and configured to be slidably mounted to a rail. The slider block includes a segmented body including a pair of longitudinal segments and a lateral segment, and a retainer disposed at an lateral interface of the pair of longitudinal segments and the lateral segment, wherein the retainer is configured to receive a second end of the pivot arm, wherein the pair of longitudinal segments and the lateral segment of the segmented body are each configured to move relative to one another in response to insertion of the second end of the pivot arm into the retainer.

A minimally invasive bone fracture positioning device includes a sleeve, a movable unit, and a support. The sleeve includes an alignment portion located on a longitudinal axis of the sleeve. The movable unit includes a positioning portion. The positioning portion is located on the longitudinal axis and is spaced from the alignment portion. The movable unit is mounted in a radial direction of the sleeve. The movable unit is slideable relative to the sleeve along the longitudinal axis. A support is coupled to the sleeve and the movable unit. The movable unit is spaced from the sleeve by the support.

An elastic traction system, including a driving mechanism to provide traction power, a connecting rod connected to an output shaft of the driving mechanism and rotating along with the output shaft, a traction wheel arranged at an end of the connecting rod for rotating along with the connecting rod, a traction wire connected to the traction wheel, and an elastic traction bow connected to the traction wire. An elastic body is arranged at a front end of the traction wire to be connected to various traction tools, the other end of the traction wire is wound around the traction wheel, and the traction wheel is driven by the traction system to rotate, so as to complete a traction operation. The elastic traction bow implements elastic traction of a fracture reduction surgery, provides an elastic activity space for a surgical operation, and greatly facilitates carrying out various reduction operations during traction.

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.
