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 polyaxial external fixation strut including a strut member and a first ball joint coupled to an end portion of the strut member. The first ball joint includes a first ball joint body and a first ball member. The first ball member is rotatably coupled to the first ball joint body to allow for variable angle adjustable positioning of the first ball member within the first ball joint body. The first ball joint additionally includes a friction member. The friction member is configured to create friction between the first ball member and the first ball joint body.

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.

A self-locking spindle traction mechanism for use in surgical procedures has a longitudinal axis (L). The mechanism may include an operating end, a connecting end for connecting a surgical accessory, and a threaded spindle drive. The spindle drive may include a spindle having an external thread, and a spindle nut that is seated on the spindle and has an internal thread. The mechanism may include a slide that is movable along the longitudinal axis by a relative rotation between the spindle and the spindle nut, a drive device that is situated on the operating end for rotationally driving the threaded spindle drive, and a gear. The gear may be connected between the drive device and the threaded spindle drive, so that the gear is configured for stepping up the speed of a rotational movement of the drive device and delivering it to the threaded spindle drive.

The present invention includes a system, kit and apparatus to aid in the realignment of one or more bones of a patient. The present invention provides a substantially rigid orthopedic stabilization scaffold for attachment of one or more external fixators for the realignment of one or more bones of a patient. The orthopedic stabilization scaffold includes a first anchorable frame and a second anchorable frame that are removably attachable to an operating table and connected adjustably by one or more crossbars.

An active variable stiffness clamping device for pelvic fracture reduction robot, belonging to the technical field of medical robots. The clamping device includes an affected side adjusting support module and a healthy side fixing module which are in fit with each other. The affected side adjusting support module is provided with a pair of electric pin rod connector modules connected to the affected side adjusting support module. The healthy side fixing module includes a healthy side bed clamp seat, the healthy side bed clamp seat is provided with a healthy side support rod, the healthy side support rod is provided with a healthy side spherical hinge base, and the healthy side spherical hinge base is provided with a pair of healthy side fixers which are in clearance fit with each other.

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.
