Abstract: The present invention provides a spinal plate which is used to perform fixation surgery on a spine in orthopedic surgery and neurosurgery. The spinal plate comprises a central body and a pair of rotation portions which are disposed on both sides in a longitudinal direction of the central body and each of the pair of rotation portions has bone screw. The spinal plate also comprises spike screw in each of the pair of rotation portions. Each of the pair of rotation portions include a rotation connection portion, and the central body includes a rotation support portion. Rotation pins are used to connect the central body with the pair of rotation portions disposed on both sides in a longitudinal direction of the central body and enable the pair of rotation portions to rotate clockwise or counterclockwise with respect to the central body.

Abstract: A reducer comprises a reducing shaft for engaging a stabilization member, a reducer body for engaging a pedicle screw extender and receiving the reducing shaft along an axis, and one or more of a three-pawl clutch mechanism, a three-stage locking mechanism and a closure mechanism. The clutch mechanism comprises a clutch housing comprising a central passage into which the reducing shaft extends and ports intersecting the central passage, a clutch knob surrounding the clutch housing, and clutch pawls disposed within the ports. The locking mechanism attaches the reducer body to the pedicle screw extender and comprises a first pivoting lever comprising a toothed end, a second pivoting lever comprising a socket for engaging the tooth, and a protrusion configured to engage the pedicle screw extender. The closure mechanism comprises a driver shaft extending through the reducing shaft and a biasing element to bias the driver shaft to a retracted position.

Abstract: The invention relates to a medical system comprising a tool including: a body; a location measurement device adapted to emit an ultrasound location signal and receive a reflected location signal; a location processing device adapted to compare each of the echoes of the reflected location signal to a pre-determined location threshold, emit an information signal if no target location echo corresponding to the interface between first and second anatomical structures has been identified within an analysis time window, the target location echo having an amplitude that exceeds the location threshold.

Abstract: A surgical implant device configured to adjust in planar orientation or angular orientation or both to correspond to the structure of the lamina to be spanned at the site of a cut of the laminoplasty surgery. The device includes a base having slots extending adjacent thereto, and an extension having a head configured to be adjustably positionable within the slots.

Abstract: In some embodiments, a spinal stabilization system may be formed in a patient using quick-connect sleeve assemblies. Each quick-connect sleeve assembly can be coupled to a bone fastener assembly in a fast and intuitive way. In one embodiment, a quick-connect sleeve assembly has a detachable member and a movable member. Both members engage a collar of the bone fastener assembly. In one embodiment, the engagement can be locked via one or more locking features to facilitate screwing a bone fastener of the bone fastener assembly onto a vertebral body in a minimally invasive surgical procedure. Each quick-connect sleeve assembly has a low profile and is particularly shaped for minimally invasive entry.

Abstract: A single device desirably configured for use at complete cut location of an open door laminoplasty surgical site, and to be adjustable in size and orientation so that they may be adapted to the site at the time of surgery. The device is a one-piece construct of a base with an integrated spacer, with an extension hingedly connected to the base. The base and spacer are integrally formed of material that is not bone or bone-like, such as titanium. The spacer is devoid of void or open areas and includes arched proximal ends.

Abstract: The present invention provides a spinal plate which is used to perform fixation surgery on a spine in orthopedic surgery and neurosurgery. According to the present invention, a rotation device and a locking device may be installed so as to be used by fixing any one or more of longitudinal ends of the plate with being rotated at any angle, thereby allowing a doctor to modify a shape of the spinal plate to the shape desired by the doctor, and to perform the surgery by coping with various spin shapes of patients. In addition, according to the present invention, since the shape of the spinal plate may be rotated at any angle, it is possible to cope with various spin shapes of the patients.

Abstract: Embodiments described herein provide systems and methods for vertebral reduction using sleeves detachably coupled to collars of bone fasteners. The reduction can be performed during a minimally invasive procedure for implanting spinal stabilization systems. A sleeve can include internal threads that match threads on the respective collar to form a continuous set of threads. Threads on a closure member can be engaged with the threads on the sleeve and the closure member turned to translate the closure member along the sleeve. The closure member can be used to push a rod relative to the collar to which the sleeve is attached to cause a vertebral body to move.
