Staple Instrument
There is provided a staple instrument for inserting and removing staples from bone. A rotational drive shaft is turned to provide finite adjustments to open and close jaws used to hold and adjust the legs of a staple. A converter coupling converts the rotational motion of the drive shaft to liner motion to operate an articulated linkage system that moves the jaws. The jaws include a sharp edge to engage under a bridge of a staple inserted in bone segments and a convex pry surface that cooperates with the edge to pry a staple from the bone segments when the instrument is pulled away from the bone segments.
MEDICAL IMPLANT DELIVERY SYSTEM AND RELATED METHODS
An implant delivery system including a fixation member delivery system including an elongate shaft, first and second rails, a plurality of fixation members with each fixation member slidably disposed on the first and second rails and an actuation assembly. The actuation assembly includes a first elongate member including a first plurality of engagement members disposed along the first elongate member with a distal end region of each engagement member in engagement with one of the fixation members, a second elongate member including a second plurality of engagement members disposed along the second elongate member with a distal end region of each engagement member in engagement with one of the fixation members. Additionally, cyclical actuation of the actuation assembly is configured to incrementally move the fixation members distally along the first and second rails to deploy each of the plurality of fixation members in sequence.
DUAL-FUNCTION ANCHOR SYSTEM
The present invention provides a surgical anchor comprising a screw and a coil; said coil having a conical shape, wound around the screw shaft with the first end of the coil being tapered and having a ring circumference smaller than that of the screw head and being engaged to the bottom of the screw head and the second end of the coil being flared with a larger ring circumference and positioned along the screw shaft.
SYSTEMS AND METHODS FOR JOINT FUSION
Apparatus and methods are disclosed for correcting deformities in a patient's foot. In one example, a metatarsus adductus is addressed using a pin placement guide that is angulated to be placed in alignment with a cuneiform and a metatarsal, such that the TMT joint can be subsequently cut, and the metatarsal moved into proper alignment. Th pin placement guide can be a variable angle guide, or a kit of fixed-angle pin placement guides can be provided.
Method and apparatus for bone fixation
An orthopedic implant can be used for fixation of a joint or fracture and can include a tapered member and at least one fixation member. The tapered member can be configured for placement in association with one or more bone segments. The tapered member can have a longitudinally extending body that defines an upper surface portion, an opposed lower surface portion and first and second sides, where at least the first and second sides can be formed of porous metal and can have a porous metal outer surface. The at least one fixation member can be integrally formed with the tapered member and can extend laterally outwardly from the tapered member body. The at least one fixation member can be configured to secure the implant to the one or more bone segments to provide fixation of the one or more bone segments relative to the tapered member.
METHODS AND APPARATUS FOR RADIALLY COMPRESSIVE SHAPE MEMORY IMPLANTS
A radially compressive implant, which includes a central vertical axis, is configured to transition between a natural shape and an insertion shape. A transition of the implant from the natural shape to the insertion shape facilitates the implant storing energy deliverable radially relative to the central vertical axis. A transition of the implant from the insertion shape toward the natural shape facilitates the implant delivering the energy stored therein radially relative to the central vertical axis. An implant delivery device in an implant engagement position is configured to engage the implant and constrain the implant in the insertion shape. The implant delivery device in an implant release position is configured to release the implant.
Surgical bending instrument
A system and a method are provided for a surgical bending instrument for bending surgical implants. The surgical bending instrument comprises a body including a center lever comprising a wheel and a cam. A distal force applicator comprises a driver centered between a first grip and a second grip. In some embodiments, the distal force applicator is configured to retain a surgical staple, such that the surgical staple may be changed to a distracted configuration suitable for implantation at a bone fixation or fusion site of a patient. In some embodiments, the distal force applicator is configured to bend a bone fusion plate so as to tailor the plate to specific anatomy of the patient's bone.
VERTEBRAL JOINT IMPLANTS AND DELIVERY TOOLS
A spinal joint distraction system for treating a facet joint including articular surfaces having a contour is disclosed and may include a delivery device including a generally tubular structure adapted to engage a facet joint, an implant adapted to be delivered through the delivery device and into the facet joint, the implant comprising two members arranged in opposed position, and an implant distractor comprising a generally elongate member adapted to advance between the two members of the implant causing separation of the members and distraction of the facet joint, wherein the implant is adapted to conform to the shape of the implant distractor and/or the articular surfaces of the facet upon being delivered to the facet joint. Several embodiments of a system, several embodiments of an implant, and several methods are disclosed including a method for interbody fusion.
DEVICE AND ASSEMBLY FOR REPAIRING SOFT TISSUES, FOR EXAMPLE TENDONS AND LIGAMENTS
A bio-compatible and bio-resorbable implantable device for repairing soft tissue which has a first plate and a second plate and a plurality of connecting elements for connecting the first and second plates is provided. The first plate has a first surface suitable for being placed on a first side of the soft tissue. The second plate has a second surface suitable for being placed on a second side of the soft tissue. Each connecting element has a first portion integral with the first plate and a second portion integral with the second plate. The connecting elements extend from at least one of the first surface of the first plate and the second surface of the second plate to reach the other one of the first surface of the first plate and second surface of the second plate for locking the first and second plates in a definable respective position.
Orthopedic implant, method, and kit
Disclosed in an orthopedic implant that comprises a spacer portion having a superior portion and an inferior portion, and a staple portion. The staple portion is integral with the spacer portion and comprises a crown portion and first and second leg portions, the first and second leg portions having distal end that converge from the crown portion and that are composed of a material that has superelastic properties at body temperatures, whereby the first and second leg portions are configured to impart a compressive biasing force when the implant is installed with the legs under tension.
