摘要： Surgical support instruments are described herein that can couple to, e.g., an implanted anchor and provide a platform for coupling other surgical implements thereto. In one embodiment, an instrument can include an elongate body having opposed projections extending laterally from a distal portion thereof that can at least partially surround a shank of an implantable anchor such that a longitudinal axis of the elongate body is laterally offset from a longitudinal axis of the anchor. The instrument can further include a lock configured to exert a drag force on a head of the anchor to control polyaxial movement of the instrument relative to the anchor. Further, a proximal portion of the elongate body can be configured to receive a retractor assembly including a plurality of tissue manipulating implements and selectively lock the retractor assembly at any of a plurality of positions along a length of the elongate body.

摘要： A control member for mounting to an end of an access tube includes a body that defines a proximal end and a distal end spaced from each other along a central axis. The control member defines a bore extending between the proximal and distal ends along the central axis, a handle portion that extends to the proximal end, and a mounting formation that extends to the distal end. The mounting formation includes an insertion portion that is insertable within the access tube and a lip that is opposed to the insertion portion so as to define a receptacle configured to receive an end portion of the access tube.

摘要： A retractor member is configured for insertion through a channel of an access member and for moving soft tissue at a treatment site that is accessible through the channel. The retractor includes a body having a proximal end and a distal end and spaced from each other along a longitudinal direction. The distal end defines a retractor blade and the body defines a first surface and a second surface opposite each other along a transverse direction substantially perpendicular to the longitudinal direction. The retractor includes an attachment device configured to selectively attach the body to a portion of the access member such that the body is extendable through the working channel while the body is attached to the portion of the access member.

摘要： Surgical tissue retraction systems and methods are described herein. Such systems and methods can be employed in some embodiments to provide medial-lateral tissue retraction to increase access to a surgical site. In one embodiment, a surgical instrument can include a body configured to couple to an implantable anchor, a first tissue manipulating implement coupled to the body and capable of polyaxial movement relative thereto, and a second tissue manipulating implement coupled to the body and capable of polyaxial movement relative thereto. Further, the first and second tissue manipulating implements can be opposed to one another such that they can move any of toward and away from one another.

摘要： Connectors for connecting or linking one instrument or object to one or more other instruments or objects are disclosed herein. In some embodiments, a connector can include a first arm with a first attachment feature for attaching to a first object, such as a surgical access device, and a second arm with a second attachment feature for attaching to a second object, such as a support. The connector can have an unlocked state, in which the position and orientation of the access device can be adjusted relative to the support, and a locked state in which movement of the access device relative to the support is prevented or limited. Locking the connector can also be effective to clamp or otherwise attach the connector to the access device and the support, or said attachment can be independent of the locking of the connector.

摘要： Embodiments of bone and tissue resection devices are disclosed herein. In one embodiment, a device can include a stationary assembly having a housing, an elongated sleeve extending distally from the housing, and a cutting region disposed distal to the sleeve. The device can further include a drive assembly having a blade shaft extending through the elongated sleeve, the blade shaft having a distal tip with a cutting surface configured to extend into the cutting region when the drive assembly advances distally relative to the stationary assembly. The drive assembly can further include an oscillator coupled to the blade shaft and configured to engage with a source of continuous rotational motion to convert the continuous rotational motion into oscillating motion of the drive shaft. Further, the drive assembly can be configured to slidably couple to the stationary assembly to permit selective translation of the drive assembly relative to the stationary assembly.

摘要： A system for delivering flowable biomaterial to an intervertebral disc space between adjacent vertebral bodies includes a delivery body defining a proximal end, a distal end spaced from the proximal end along a longitudinal direction, a cannulation extending from the proximal end to an opening adjacent the distal end, and a distal region including a tip that extends to the distal end. The distal region defines a maximum height at a location proximal of the distal end and measured along a second direction perpendicular to the longitudinal direction. The distal region is for indicating a distance between the adjacent vertebral bodies. The system includes a carrier having a longitudinally elongate channel for carrying biomaterial and being insertable within the cannulation, as well as an advancement member configured for insertion within the cannulation to forcibly advance the biomaterial from the cannulation, through the opening, and into the disc space.
