Abstract
A surgical method utilizes a surgical instrument having an elongate probe with a distal end having at least one egress or outlet port. The method comprises inserting a distal end portion of the elongate probe into a spinal disc space adjacent two spinal vertebrae, ejecting or streaming a plasma jet from the at least one egress or outlet port into spinal disc material in the spinal disc space, and subsequently removing the elongate probe from the spinal disc space.
Claims13
A surgical method comprising:
- providing a surgical instrument including an elongate probe with a distal end having at least one egress or outlet port;
- inserting a distal end portion of said elongate probe into a spinal disc space adjacent two spinal vertebrae;
- generating plasma outside of the spinal disc space;
- conducting the plasma through said elongate probe;
- emitting or ejecting the plasma as a plasma jet from said at least one egress or outlet port into spinal disc material in said spinal disc space in a predetermined amount effective to vaporize tissue and other organic material at the surgical site at or in a spinal disc space;
- and
- subsequently removing said elongate probe from said spinal disc space.

A surgical method comprising:
- providing a surgical instrument including an elongate probe with a distal end having at least one egress or outlet port;
- inserting a distal end portion of said elongate probe into a spinal disc adjacent two spinal vertebrae;
- prior to the inserting of said distal end portion of said elongate probe into said spinal disc, operating said surgical instrument to direct a plasma jet towards an outer surface of the spinal disc;
- by operating said surgical instrument to direct said plasma jet towards the spinal disc, forming at least one incision in said spinal disc, thereby enabling the inserting of said distal end portion of said elongate probe into said spinal disc;
- after the inserting of said distal end portion of said elongate probe into the spinal disc, emitting or ejecting the plasma from said at least one egress or outlet port into spinal disc material between said two spinal vertebrae in a predetermined amount effective to vaporize tissue and other organic material at the surgical site at or in a spinal disc space;
- and
- subsequently removing said elongate probe from said spinal disc.

A surgical method comprising:
- conducting a surgical procedure on a patient to enable access to a spinal disc space adjacent two spinal vertebrae;
- inserting a distal end portion of a plasma jet instrument into the spinal disc space;
- generating plasma outside of the spinal disc space;
- after the inserting of said distal end portion of said plasma jet instrument into said spinal disc space, conducting the plasma through said plasma jet instrument;
- and
- operating said plasma jet instrument to direct the plasma as a jet stream toward tissue and spinal disc material in said spinal disc space to thereby ablate the tissue and spinal disc material.

A surgical method comprising:
- conducting a surgical procedure on a patient to enable access to a spinal disc space adjacent two spinal vertebrae;
- inserting a distal end portion of a plasma jet instrument into the spinal disc space;
- prior to the inserting of said distal end portion of said plasma jet instrument into said spinal disc space, operating said plasma jet instrument to direct a plasma jet towards an outer surface of a spinal disc in said spinal disc space between said adjacent spinal vertebrae;
- by the operating of said plasma jet instrument to direct said plasma jet towards said outer surface of said spinal disc, forming at least one incision in said spinal disc, thereby enabling the inserting of said distal end portion of a plasma jet instrument into said spinal disc space;
- and
- operating said plasma jet instrument to ablate tissue and spinal disc material in said spinal disc space.
