A rod reducer assembly is provided and is selectively mountable to a pedicle screw assembly. The pedicle screw assembly includes a pedicle screw housing that defines a rod-receiving recess. The pedicle screw assembly includes an extension assembly that is coupled to the pedicle screw housing by a frangible member. The rod reducer is configured to reduce a spinal rod into the rod-receiving recess of the pedicle screw assembly. The rod reducer assembly may include a derotation sleeve configured to inhibit the frangible member from breaking while manipulating a spinal bone.

Rod reducer assembly

A liquid dispenser is provided. The liquid dispenser includes a reservoir portion having a first circumferential sidewall, a first partition and an opposing second partition. The first circumferential sidewall and first and second partitions define an interior chamber. A dispenser portion extends from the first partition and has a neck defined by a second circumferential sidewall. The second circumferential sidewall defines a first internal passage. A bottom portion extends from the second partition and has a third circumferential sidewall. The third circumferential sidewall and the second partition define an internal cavity. A base assembly has a pivotable lid and is configured for a first, seated orientation within the internal cavity of the bottom portion and a second, seated orientation on the first partition. In the second orientation, the pivotable lid allows fluid access to the first internal passage of the dispenser portion.

Pump-type liquid dispenser

A combination duster and sprayer device for both cleaning and spraying insecticide includes a housing that is tubular and has a bottom. The housing has a top that is open defining a rim, such that the housing is configured for insertion of an aerosol can. A coupler is coupled to the bottom, such that the coupler is configured to engage a complimentary connector of an extension device. A casing that has an open end is complimentary to the housing, such that the housing is insertable into the casing. The housing is frictionally couplable to the casing. A plurality of bristles is coupled to and extends outwardly from the casing. The bristles are pliable. An opening is positioned in a closed end of the casing. An actuator is insertable into the opening and configured to engage the nozzle of an aerosol can to direct spray to the area selected by the user.

A telescopic insertion assembly is configured to insert a pedicle screw into a vertebral body. The insertion assembly includes an attachment fixture having one end configured to mate with the pedicle screw and another end having a ridged portion. A center tube is provided having one end slidably attached to the attachment fixture and another end having an internally ridged portion. A telescoping member has one ridged end configured to slidably attach to the center tube and another end having a yoke. The telescoping member is configured to extend the yoke to different distances from the center tube. An alignment member is configured to hingeably attach to the yoke of the telescoping member. The alignment member is configured to rotate from a first position to a second position. The second position of the alignment member is above a top surface of a patient's skin.

Insertion assembly for minimally invasive spinal surgery

A cervical plate assembly facilitates the fusion of cervical vertebrae by quickly and easily causing the vertebrae to exert a preloading force against a bone graft interposed therebetween. A cervical plate assembly also facilitates the installation of the cervical plate assembly in an orthopedic surgical procedure by providing both a locking mechanism that positively retains one or more fasteners thereto and a viewing window that results in an unobstructed view of the vertebrae and the bone graft.

A pedicle screw assembly has a retractable screw tip that facilitates the securement of the pedicle screw assembly to a spinal vertebra in a minimally invasive fashion during an orthopedic surgical procedure. The pedicle screw assembly includes a body portion including a head and a shank. The shank includes an outer surface with a thread provided thereon, an end having a cutting tip provided thereon, and a bore extending inwardly from the end and having an internally threaded region provided therein. The pedicle screw assembly also includes a tip portion including a body having a cutting edge and a shank extending from the body. The shank has an externally threaded region provided thereon that cooperates with the internally threaded region of the bore to permit movement of the tip portion relative to the body portion between extended and retracted positions.

A scoliosis correction device includes a first fixed anchor that is adapted to be secured to a vertebra of a spine and a second fixed anchor that is adapted to be secured to a vertebra of a spine. A rotatory anchor includes a head portion, a shank portion that extends from the head portion and is adapted to be secured to a vertebra of a spine, and a sprocket that is supported on the head portion for rotational movement relative thereto. A cable extends from the first fixed anchor to the rotatory pedicle screw to the second fixed anchor. The rotatory anchor may be configured to allow unidirectional movement of the sprocket relative to the head portion. A rigid member may extend between the fixed anchor and an intermediate anchor.

A needle for use in a surgical procedure includes an outer cannula including a shaft portion having a side wall and an end wall. A first aperture extends through the side wall of the outer cannula, and a second aperture extending through the end of the outer cannula. The needle also includes an inner cannula that is disposed within the outer cannula and includes a shaft portion having a bore extending therethrough. The inner cannula is selectively movable relative to the outer cannula between a first orientation and a second orientation. In the first orientation, communication is provided between the bore of the inner cannula and a first external region that is located adjacent to the second end of the outer cannula. In the second orientation, communication is provided between the bore of the inner cannula and a second external region that is located adjacent to the second end of the outer cannula.

A lateral fixation assembly engages vertebrae in a spinal column. The lateral fixation assembly includes a housing having a first rod and a second rod supported thereon. The first rod is adapted to be secured to a first vertebra in the spinal column and is fixed in position relative to the housing. The second rod is adapted to be secured to a second vertebra in the spinal column and is movable relative to the housing. Respective pluralities of such first and second rods may be provided. Staples having varying thicknesses may be provided to facilitate the installation of the lateral fixation assembly on the vertebrae in the spinal column. A temporary blocking device can be used to prevent relative movement of the movable rod during the installation of the lateral fixation assembly.
