Spinal deformity sequential persuader

A persuader instrument for advancing a fixation rod into a vertebral implant includes a housing and at least one arm. The at least one arm can include detents for detachable connection to the vertebral implant. The persuader instrument can also include a shaft coupled to an anchor. The anchor can include a fixation rod engagement surface. The shaft can be axially displaceable through the housing to axially displace the anchor and a rod engaged by the anchor. The persuader instrument can further include an auto-locking ratchet assembly in releasable engagement with the shaft. The auto-locking ratchet assembly can control axial displacement of the shaft through the longitudinal passage of the housing.

Minimally invasive spinal fixation system

This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. More specifically, the application describes instruments and methods for building a posterior fixation construct across one or more segments of the spinal column in a minimally invasive fashion.

LATERAL ROD REDUCER
20230143005 · 2023-05-11 · ·

The present invention is directed to a rod reducer that is both a lateral rod reducer and an axial rod reducer that uses an entirely different mechanism never before used for lateral rod reduction. The lateral rod reducer is configured to move a spinal fixation rod that is not aligned with the pedicle screw to a position above the tulip slot or U-shaped channel. Once in position, the lateral rod reducer also provides an axial rod reducer to advance the spinal fixation rod axially into the tulip slot. Splitting the reducer body geometry to create a hinged jaw that is then driven by a linkage system is novel. The lateral rod reducer of the present invention allows for incremental lateral reduction that utilizes a threaded linkage feature for increased power/mechanical advantage when laterally reducing. This will allow for new techniques of lateral rod manipulation in deformity cases.

MINIMALLY INVASIVE SPINAL FIXATION SYSTEM AND RELATED METHODS

This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. More specifically, the application describes instruments and methods for building a posterior fixation construct across one or more segments of the spinal column in a minimally invasive fashion.

MINIMALLY INVASIVE SPINAL FIXATION SYSTEM AND RELATED METHODS

This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. Extension guides are provided that attach to bone anchors implanted within the spine. The extension guides have a guide channel that align with a rod channel in the anchor to help direct the rod to the anchor. Instruments are provided to aid in insertion and positioning or the rod.

Transverse, and surgical instrument

Problem to be Solved A traverse that is percutaneously provided and a surgical instrument for percutaneously providing the transverse are provided. Solution A rod 10 is placed in each of two rod openings 113, 123 and a transverse bar 130 is inserted in two bar holes 111, 121. Set screws 140, 150 are screwed in screw holes 114, 124. The set screws 140, 150 press the transverse bar 130, thereby restraining the transverse bar 130 in the longitudinal direction. Since portions of the bar holes 111, 121 adjoin the rod openings 113, 123, the pressed transverse bar 130 contacts the rods 10 and pushes the rods 10 against the rod openings 113, 123. A protrusion 127 engages with the rods 10 to restrain hooks 110, 120 in the longitudinal direction and circumferential direction of the rods 10.

Deformable device for minimally invasive fixation

The present teachings provide one or more surgical implements for repairing damaged tissue, such as through a fixation procedure. A system for a percutaneous procedure is provided. The system can include a bone fastener including a receiver. The system can include a device having a first end, a second end and a middle portion. The first end, middle portion and second end can be disposed along a longitudinal axis, and the second end can be connected to the receiver. The middle portion can have a pair of deformable leg members extending between the first and second ends. The leg members can define a channel having a width. The leg members can be selectively movable between a retracted state and an expanded state with the width of the channel greater in the expanded state than in the retracted state.

SYSTEM OF A ROD INSERTION DEVICE AND A ROD
20220039845 · 2022-02-10 ·

A system for spine surgery includes a rod with a longitudinal axis and a connection portion, and a rod insertion device including a rod holding member with a central axis and a rod engagement portion, wherein at least part of a shape of the rod engagement portion substantially matches at least part of a shape of the connection portion to engage the connection portion in a fixed manner at more than one distinct rotational orientation around the longitudinal axis. When the connection portion is engaged with the rod engagement portion, when viewed in a plane perpendicular to the longitudinal axis, a cross-section of the connection portion has a maximum height measured in a direction of the central axis of the rod holding member that is greater than a maximum width of the connection portion measured in a direction transverse to the longitudinal axis.

Bi-planar persuader

The present disclosure relates generally to surgical instruments for spinal surgery. More specifically, the present disclosure relates to a bi-planar rod persuader for urging a spinal rod into a screw, and methods regarding the same. The bi-planar rod persuader may include an implant holder, which may also include a holding sleeve. A securing foot may be attached to the distal end of the holding sleeve, and the holding sleeve may also include a threaded opening at the proximal end for receiving a stem that drives the securing foot between a first position and second position. The implant holder may also include a threaded part to engage a reduction knob. A handle assembly may also be provided, which may include two pivotally attached arms. A rod hook may be connected to one of the arms and a guide attached to the other of the arms.
