Abstract
A novel device and method for surgical inducement of cervical vertebra fusion as a treatment for cervical spinal disease using a guide wire, slide knife, and a minimally invasive portal access device and an inter-vertebra linking member.
Claims6
An apparatus for the minimally invasive surgical implantation of instrumentation to aid in bone fusion of two adjacent vertebra, the apparatus comprising:
- a docking rod suitable to be posteriorly purchased within and parallel to the facet joint of said two adjacent vertebra;
- a cauterizing slide knife possessing a cannulated shaft and a blade having a cutting edge;
- a cannulated minimally invasive portal access device, said minimally invasive portal access device having a maximum diameter smaller than the height said cauterizing slide knife;
- and
- an inter-vertebra linking member, said inter-vertebra linking member being releasably attached to said cannulated surgical minimally invasive portal access device;
- wherein when said docking rod is posteriorly purchased within and parallel to said facet joint of said two adjacent vertebra and said cannulated shaft of said cauterizing slide knife is placed over said docking rod, said cutting edge of said blade is approximately parallel with the posterior surface of said two adjacent vertebras' lateral masses.
An apparatus for the minimally invasive surgical implantation of instrumentation to aid in bone fusion of two adjacent vertebra, the apparatus comprising:
- a cannulated docking rod suitable to be posteriorly purchased within and parallel to the facet joint of said two adjacent vertebra, said docking rod able to be inserted over a guide wire;
- a cauterizing slide knife possessing a cannulated shaft and a blade having a cutting edge;
- a cannulated minimally invasive portal access device, said minimally invasive portal access device having a maximum diameter smaller than the height said cauterizing slide knife;
- and
- an inter-vertebra linking member, said inter-vertebra linking member being releasably attached to said cannulated surgical minimally invasive portal access device;
- wherein when said docking rod is posteriorly purchased within and parallel to said facet joint of said two adjacent vertebra and said cannulated shaft of said cauterizing slide knife is placed over said docking rod, said cutting edge of said blade is approximately parallel with the posterior surface of said two adjacent vertebras' lateral masses.
A method for the minimally invasive surgical implantation of instrumentation to aid in bone fusion of two adjacent vertebra, the method comprising:
- purchasing a docking rod within and parallel to the facet joint of said two adjacent vertebra;
- sliding a cauterizing slide knife down said docking rod, said cauterizing slide knife being guided by said docking rod, thereby creating an operating portal;
- sliding a cannulated minimally invasive portal access device over said docking rod, and down within said operating portal;
- and
- fastening an inter-vertebra linking member, said inter-vertebra linking member being releasably attached to said cannulated surgical minimally invasive portal access device.
