摘要:
A textile-based plate implant (and related methods) that supports tissue ingrowth within the implanted implant structure and is suitable for use in a variety of surgical applications, including but not limited to anterior, posterior and lateral surgical approaches directed towards the lumbar, thoracic and cervical regions of the spine.
摘要:
Total disc replacement systems and related methods involving a lateral, trans-psoas surgical approach to the spine while performing at least one of continuous and intermittent intra-operative neural monitoring of the psoas muscle to avoid injury during introduction.
摘要:
Disc prostheses, particularly for use in the lumbar region of the spine are provided. The disc prosthesis includes a core comprising one or more filling elements provided within an inner component of fabric. The inner component is provided within an outer component of fabric. By providing a smooth inner contact surface between the inner component and the core filling, movement between the inner and outer components is facilitated in preference to movement between the inner component and core. Core abrasion is thus avoided. The use of an inner component and an outer component also means that the characteristics of each can be optimised to meet different aims.

The present invention involves systems (20) and related methods for performing dynamic pedicle integrity assessments involving the use of neurophysiology.
摘要:
A surgical instrument positioning system, comprising: at least one support (20); a cross member (12) having at least one curved end portion (14), the at least one curved end portion (14) being held by the at least one support (20) such that the cross member (12) is rotatable about an axis (A) extending through a center of curvature of the at least one curved end portion (14) of the cross member (12); and at least one surgical instrument holder (40) suspended from the cross member (12). A laser alignment system for an image intensifier, comprising: at least one laser source (300) which emits planar laser beams in a first and second intersecting planes.
摘要:
A method of aligning a C-arm (26) of an image intensifier for rotation in a selected plane, the C-arm having a transmitter (22) mounted at one end and a receiver (24) mounted at an opposite end, comprising: identifying the selected plane by viewing the location of bony structure (12) with the image intensifier; and aligning indicia disposed on a radio-opaque reticle (25) covering at least a portion of the receiver with the selected plane, the indicia being aligned with the plane of rotation of the C-arm, thereby aligning the plane of the C-arm with the selected plane.
摘要:
An expandable tip cannula system, comprising: a hollow cannula shaft having a proximal end and a distal end; and an expandable tip mounted at the distal end of the hollow cannula shaft, the expandable tip comprising a plurality of generally-triangular shaped petals held together in a radially-inwardly tapered arrangement between adjacent petals, each petal comprising a nerve sensing electrode disposed therein.
摘要:
Various implementations include anchoring nails, fixation apparatuses, spinal fixation systems, and related methods described in this disclosure. Certain implementations include a fixation nail (10) for an interbody (30) fusion procedure, the fixation nail (10) including: a body (30) having an arcuate primary axis (ap) extending from a distal end to a proximal end thereof, the body (30) having an outer surface that enables complete insertion and removal of the fixation nail (10) into an interbody (30) without threaded engagement, and the body (30) further including an elongated recess (90) spanning a majority of a length of the body (30), the elongated recess (90) sized to at least partially encompass at least one of tissue or bone during insertion into a patient.
