Abstract
One embodiment of the present application is directed to a method and system for performing a unilateral surgical procedure to implant a prosthetic device between two spinous processes. During this procedure at least one side of one of the processes remains covered by soft tissue. An instrument is magnetically coupled to cabling that is routed beneath this soft tissue and remains visually hidden during such routing. The cabling is also configured to engage the prosthetic device positioned between the spinous processes.
Claims24
A method, comprising:
- performing surgery to implant a prosthesis between two spinous processes, one of the spinous processes remaining covered by soft tissue throughout the surgery;
- magnetically coupling an instrument to a cable;
- while the instrument is coupled to the cable, advancing the cable beneath the soft tissue and about the one of the spinous processes, an end portion of the cable being visually hidden during performance of the advancing;
- and
- engaging the cable to the prosthesis.
2 more elements
An apparatus, comprising:
- a surgical instrument to perform a unilateral surgical procedure to implant a prosthetic device between two spinous processes, the instrument including a longitudinal portion extending along a longitudinal axis and a first end portion, the longitudinal portion extending a greater distance along the longitudinal axis than the first end portion, the first end portion including multiple turns in different directions to laterally extend away from the longitudinal axis and provide a hook-shaped structure with a tip, the hooked-shaped structure including one or more of a first magnet and a magnetically attractable material and being shaped and sized to turn about one of the spinous processes at least 90 degrees to magnetically couple with a portion of a cable visually hidden by soft tissue covering one side of the one of the spinous processes.
A system, comprising:
- an interspinous prosthesis device structured to be implanted between two spinous processes of a spine of a patient;
- cabling to engage the prosthetic device and tissue of the patient;
- and
- a surgical instrument including a central longitudinal portion that defines a longitudinal axis and a first end portion, the longitudinal portion extending a greater distance along the longitudinal axis of the instrument than the first end portion, the first end portion including a hook-shaped structure that turns away from the longitudinal axis, the hook-shaped termination carrying one or more of a magnet and a magnetically attractable material to magnetically couple to a portion of the cabling when visually hidden by soft tissue covering at least a portion of one of the spinous processes.
1 more element
A method, comprising:
- performing a surgical procedure with a cable;
- utilizing an instrument during the procedure, the instrument including a hook-shaped structure;
- magnetically coupling the hook-shaped structure of the instrument to the cable;
- while the instrument is coupled to the cable, moving the instrument to advance the cable through tissue while at least an end portion of the cable is visually hidden beneath at least part of the tissue;
- and
- securing the cable after advancement.
