摘要： Disclosed is an expandable percutaneous sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion to a second, enlarged cross-sectional configuration. The sheath is maintained in the first, low cross-sectional configuration by a removable tubular restraint or by structural elements built into the wall of the expandable portion of the sheath. In one application, the sheath is utilized to introduce a formed in place orthopedic fixation rod such as for use in spinal fixation procedures, preparation of a spinal segment, or placement of a vertebral body spacer. The sheath can further comprise structural elements to permit re-collapse of the sheath under fluid pressure following completion of the procedure and prior to removal from the patient.

摘要： Devices and methods are provided for assisting in spinal stabilization. An access device is provided that includes an outer sleeve, inner sleeve, spring latch and lock nut. The inner sleeve includes compressible grasping elements. The access device can be coupled to a screw head by sliding the outer sleeve relative to the inner sleeve and compressing the grasping elements. The coupled access device and screw can then be delivered to a target location in a patient. After providing two or more access devices, a rod member can be delivered using a rod insertion device. The rod member can serve as a connection between the two screws, and can provide spinal stabilization. An anti-torque device and a persuading device can be used to help ensure that the rod member is placed and secured in a proper location within a patient.

摘要： An improved system and method for positioning screws and rods to immobilize bones is provided. Specifically, the system and method is optimal for performing transforaminal lumbar interbody fusion (TLIF) and other interbody fusions in the spine. The system involves pedicle screws detachably connected to wires that guide rods down to the screws. The wires are strong, narrow, flexible, adjustable in tension, and easily disconnected from the screws after rod placement via a process such as cutting, radiating, burning, dissolving, etc. The use of wires to place the rods avoids the conventional bulky tower apparatuses of the prior art while at the same time enhancing the accuracy of placement. One of the preferred methods involves relying upon the natural lordotic curvature of the spine and the narrow diameter of the wires to insert many elements through a single minimally invasive incision.

摘要： A surgical instrument for the distraction or compression of bones or bone portions comprises a pair of elongate cross members pivotally coupled for relative movement having at one end a respective pair of handles and at the other end a respective pair of jaws. The jaws are generally parallel to each other and define a first plane within which the jaws are relatively movable, the space on both sides of the plane defining a work space between the jaws. The instrument further comprises a fulcrum supported by at least one of the cross members projecting into the work space and having an axis spaced from the jaws.

摘要： The present application is directed to various spinal stabilization systems. The systems can include one or more guiding elements attached to screw members to assist in guiding rod implants and tools to desired locations within a patient. The guiding elements can include a plurality of wires, blades, or tabs. The guiding elements can be capable of criss-crossing or intersecting at or near an incision, such that only a single incision may be needed to perform a surgery. The guiding elements can also include telescoping features that allow the height of the guiding elements to be adjusted in use, thereby allowing multiple telescoping guiding elements to be used with the same incision.

摘要： Featured are methods for fixing adjacent vertebrate of a spine that utilize an implant member, which preferably is arcuate. Preferred methods of the invention for stabilizing adjacent vertebrae of the spine, include forming an aperture in each of the adjacent vertebrae and inserting an implant into the apertures formed in each of the adjacent vertebrae so that the implant extends between the adjacent vertebrae and through the intervertebral space. An alternative method for fixing adjacent vertebrae of a spine includes the step of forming a common channel in and between the adjacent vertebrae and inserting an implant in the channel so as to bridge between the adjacent vertebrae. Also featured are methods for stabilizing adjacent segments of a bone, fixation systems and fixation kits.

摘要： Devices to grasp a medical element that may include a first member, a second member that fits within the first member, and a locking element. The first and second members may move relative to one another to move the locking element between locked and unlocked positions. In an unlocked position, the device may move along the element. In the locked position, the device may lock to the element and motion is prevented. In one application, the device can be placed in the locked position to maintain a desired amount of tension on the element. Methods of grasping the medical element may include moving the first and second members relative to each other thereby moving the locking element to grasp and release the medical element.

摘要： Apparatus for applying sustained tension on tether in treatment site includes a positioning mechanism, gripping mechanism and pressurized fluid actuated mechanism. The positioning mechanism is operable to position the pressurized fluid actuated mechanism at a fixed distance relative to treatment site, and to engage a target at treatment site and secure the tether proximate to the target. The gripping mechanism is operable to selectively grip the tether and maintain tether when tether is held in tension. The pressurized fluid actuated mechanism is selectively operable to apply desired pulling force on gripping mechanism directed away from treatment site so as to transmit and apply in a sustained manner the desired pulling force on the tether independently from the tether displacement and place it under desired level of tension while the tether is being secured.

摘要： A surgical instrument for applying and fixing a fixation screw to a threaded section of a head of a bone anchorage element comprises a distal end and a proximal end, a first tool member and a second tool member. The first tool member is arranged at the distal end and adapted for engaging the threaded section of the bone anchorage element head. The second tool member is adapted for engaging a tool-engaging member of the fixation screw. The instrument is constructed such that in a working position of the instrument the second tool member is supported on the instrument in a torque proof manner relative to the first tool member about a longitudinal axis and is movable parallel to the longitudinal axis relative to the first tool member. Moreover, an osteosynthesis device comprising at least two bone anchorage elements and at least one connection member is suggested. Further, a method for fixing an osteosynthesis device on two vertebrae of a spinal column in a minimal invasive manner is proposed.
