Rigid sternal fixation
An anchor assembly, for securing a first portion and a second portion of a separated sternum, can include a lock, an anchor, and a cerclage. The anchor can include a body locatable between the first portion and the second portion of the sternum, where the body can define an end portion. The anchor can include a collar connected to the body and extending outward from the end portion of the body. The collar can engage an outer surface of the sternum to limit movement of the body beyond the outer surface of the sternum. The cerclage can be connected to and can extend from the anchor. The cerclage can be configured to at least partially surround the first portion and the second portion of the separated sternum.
APPARATUS AND METHODS FOR INTRODUCING PORTALS IN BONE
An apparatus and method for introducing portals into bone is described herein. An example apparatus for introducing portals into bone includes a handle, a base, and a driving member. The driving member can be made to project past the base by operating the handle. The base is detachable from the handle. The apparatus also includes a guide coupled at a first end to the handle and at a second end to the base. The base is detachably coupled to the guide. A base coupling detachably coupling the base to the guide includes an actuating member movable between a coupled configuration wherein the base is coupled to the guide and an uncoupled configuration wherein the base is released from the guide. The actuating member is arranged so that motion of the handle toward the base moves the actuating member from the coupled configuration to the uncoupled configuration.
Surgical Tool And Method Of Use
The present disclosure generally relates to a surgical tool for use in shoulder arthroplasty. The surgical tool includes a humeral head cut guide configured to fit within a rotator interval of a subject in need of shoulder arthroplasty. The cut guide can further include a top surface, a bottom surface, a front surface, a back surface, and at least two sides. The surgical tool can also have at least two nonconverging pin holes and a receiving portion configured to permit reversible attachment of the cut guide to an attachment arm assembly.
Intraosseous access device and locator assembly
An intraosseous access device for accessing an intraosseous space of a patient includes a manual driver and a sternal locator. The handle is connected to an inner penetrator hub, and an inner penetrator extends from the inner penetrator hub. An outer penetrator hub is releasably engaged to the inner penetrator hub. A protective cover is slidably coupled to the handle. The protective cover is operable to move from an extended position where the inner penetrator is covered, to a retracted position where the inner penetrator is exposed. The sternal locator includes a base; a collar extending from a first surface of the base for securing the intraosseous access device to restrict longitudinal separation of the intraosseous access device from the locator. The locator may be removed from the patient while the outer penetrator remains inserted in an intraosseous space of the patient.
Sternotomy closure technique using polymeric cable
A sternotomy closure technique is suitably carried out with a cerclage mechanism, which is capable of maintaining proper bony compression (within a desired range) across the sternum cut, in spite of a range of external forces and significant lateral distraction due to these external forces. The sternum fragments are aligned in apposition disposed around a longitudinal seam and secured with a resilient element. The resilient element is tensioned to a desired tension to compress the sternum to a desired compression range. The resilient element is then elongated and contracted while accepting multiple cycles of physiological distracting forces across the sternum while maintaining contact pressure across the longitudinal seam within a desired range for a length of time sufficient for bony healing. The resilient element is preferably a polymer cable comprising an elongated elastic polymeric core coaxially surrounded by a sheath woven from ultra-high molecular weight polyethylene strands.
Bone Plating Assembly Having a Screw Guide, And Related Systems And Methods
A screw guide for connecting to a bone plate includes a body having proximal and distal ends spaced from each other along a direction. The distal end has a coupling mechanism for coupling to the bone plate at an orientation. The body defines at least one channel that extends along a central axis and is configured to receive a bone fastener therein in a pre-loaded position. The coupling mechanism is configured such that the central axis substantially aligns with a central axis of a fastener hole of the bone plate when coupled to the bone plate at the orientation. The body has a retention mechanism at least partially located within the at least one channel and configured to apply a retention force to the bone fastener for retaining the bone fastener within the channel in the pre-loaded position.
Fixation devices and surgical techniques such as for rib stabilization
A system for surgically repairing a rib of a patient is described. The system can include a first rib bracket, one or more fasteners, a driver and a caddy. The first rib bracket can be configured to be fixedly attached to a first side of the rib that faces a thoracic cavity of the patient. The one or more fasteners can be configured to fixedly attach the first rib bracket to the rib. The driver can have an end effector configured to drive the one or more fasteners into the rib. The caddy can be configured to retain the one or more fasteners and deliver these to a position adjacent the rib. The end effector can engage the one or more fasteners to drive the one or more fasteners from the caddy and into the rib to fixedly attach the first rib bracket to the first side of the rib.
APPARATUS AND METHOD FOR IMPLEMENTATION OF BRIDGED STAPLE AND STERNAL PLATE
A surgical kit can include a drill plate assembly for drilling multiple pilot holes. The drill plate assembly can include a guide plate defining guide holes and a support plate defining an aperture. A gear assembly can include a receiving shaft extending through the aperture, a drive gear coupled with the receiving shaft, and follower gears engaged with the drive gear. Drill bits may be coupled with the follower gears. Rotation of the drive gear can cause rotation of the follower gears and rotation of the drill bits. The support plate may move toward the guide plate to move the drill bits through the guide holes to drill the multiple pilot holes. The kit can include an implant configured to be inserted into the multiple pilot holes. The implant may be a bridged, multi-prong staple and/or a sternal plate with fixation members.
