AI Technical Summary

Benefits of technology

The extender kit provided in this patent is designed for use in spine surgical procedures. The kit includes tools to attach an implant to the spine of a patient using distal extenders and a collar to stabilize the extenders. The collar can be attached to the extenders before or after the implant is inserted. The collar keeps the extenders parallel to each other to prevent splaying and stabilize them during the procedure. The technical effect is improved stability and alignment during spine surgery procedures.

Problems solved by technology

Non-surgical treatments, such as medication, rehabilitation and exercise can be effective, however, may fail to relieve the symptoms associated with these disorders.

Embodiment Construction

[0024]The exemplary embodiments of the collar, and the extender system including the collar, are discussed in terms of medical devices for the treatment of musculoskeletal disorders and more particularly, in terms of extenders and surgical instruments for implant delivery to a surgical site for treating a spine. It is envisioned that the collar attaches to the proximal end of the extenders so as to keep the extenders parallel to one another so as to prevent splaying and premature break-off of the extenders. The extender system can be used to introduce an implant, such as a rod or a bone fastener, for attachment to a spine. In one embodiment, a kit is provided that includes the extenders, collar, implants, such as rods and fasteners, and may also include specific surgical instruments to be used with the extender system for attachment of the implants to the spine of a patient. One or all of the components of the extender system can be disposable, peel-packed, pre-packed sterile device...

Abstract

A collar for extenders and an extender assembly including a collar is disclosed. The collar is configured to receive extenders and maintain the extenders in a parallel orientation so as to prevent splaying and premature beak-off of the extenders from the spine. Methods of use are disclosed.

Description

TECHNICAL FIELD[0001]The present disclosure generally relates to medical devices for the treatment of musculoskeletal disorders, and more particularly to a surgical system for implant delivery to a surgical site and a method for treating a spine.BACKGROUND[0002]Spinal pathologies and disorders such as scoliosis and other curvature abnormalities, kyphosis, degenerative disc disease, disc herniation, osteoporosis, spondylolisthesis, stenosis, tumor, and fracture may result from factors including trauma, disease and degenerative conditions caused by injury and aging. Spinal disorders typically result in symptoms including deformity, pain, nerve damage, and partial or complete loss of mobility.[0003]Non-surgical treatments, such as medication, rehabilitation and exercise can be effective, however, may fail to relieve the symptoms associated with these disorders. Surgical treatment of these spinal disorders includes correction, fusion, fixation, discectomy, laminectomy and implantable pr...
