Abstract
Lysing surgical instruments and related systems and methods. In some embodiments, the instrument may comprise a lysing tip comprising a plurality of beads and at least one lysing member defining at least one lysing segment extending between each pair of adjacent beads or between a tip of the instrument and an adjacent bead. Some embodiments may comprise rearward-facing lysing segments to facilitate retrograde lysing movement through patient tissue.
Claims14
A surgical lysing device, comprising:
- a shaft;
- a lysing tip positioned at a distal end of the shaft;
- a first bead positioned at a first end of the lysing tip;
- a second bead positioned at a second end of the lysing tip opposite from the first end;
- a nonconductive strut extending between the first bead and the second bead, wherein the nonconductive strut is configured to receive one or more lysing members therein;
- at least one distal conductive lysing segment between each pair of adjacent beads of the lysing tip at a distal end of the lysing tip, wherein the at least one distal conductive lysing segment is configured to deliver energy to tissue during a surgical procedure;
- and
- at least one proximal conductive lysing segment positioned within at least one proximal recess, wherein the at least one proximal conductive lysing segment faces at least generally in a proximal direction relative to the surgical lysing device, and wherein the at least one proximal conductive lysing segment is configured to deliver energy to tissue during a surgical procedure.

A surgical lysing device, comprising:
- a shaft;
- a lysing tip positioned at a distal end of the shaft;
- a first bead positioned at a first end of the lysing tip;
- a second bead positioned at a second end of the lysing tip opposite from the first end;
- a nose extending from the shaft in between the first bead and the second bead, wherein a distal portion of the first bead defines a first protrusion, wherein a distal portion of the second bead defines a second protrusion, and wherein the nose defines a third protrusion;
- a first strut extending between the first bead and the nose, wherein the first strut at least in part defines a distal recession and a proximal recession;
- a second strut extending between the second bead and the nose, wherein the second strut at least in part defines a distal recession and a proximal recession;
- and
- at least one electrode defining at least one distal lysing segment at a distal end of the lysing tip, wherein the at least one distal conductive lysing segment is configured to deliver energy to tissue during a surgical procedure, wherein the at least one electrode further defines at least one proximal lysing segment at a proximal end of the lysing segment, wherein the at least one proximal lysing segment is configured to deliver energy to tissue during a surgical procedure.
