Abstract
A fluid source on a carrier is configured to rotate relative to a probe to direct a fluid stream from the source toward an opening of an evacuation lumen. This may help to remove material that may collect near the opening, such as blood clots and tissue. Also, directing the fluid stream toward the evacuation lumen can draw flowable material from the surgical site toward the evacuation lumen to improve removal of material from the surgical site.
Claims16
An apparatus to treat tissue at a surgical site of a patient, the apparatus comprising:
- an elongate carrier comprising a nozzle configured to emit a fluid stream, the elongate carrier comprising a longitudinal axis;
- and
- a probe configured for insertion into a patient, the probe comprising an evacuation lumen to remove material from the surgical site, the evacuation lumen extending to an opening;
- wherein the fluid stream comprises a jet, and wherein the opening comprises a cross-sectional area sized larger than the jet and wherein the probe extends beyond the elongate carrier to at least partially define the opening and wherein the probe comprises a portion with a recess sized and shaped to receive a distal end of an energy delivery probe extending from the elongate carrier to stabilize the energy delivery probe;
- wherein the elongate carrier is configured to rotate the nozzle around the longitudinal axis to a first position toward the opening to direct the fluid stream toward the opening of the evacuation lumen;
- wherein the elongate carrier is configured to rotate the nozzle around the longitudinal axis to a second position opposite the first position and away from the opening to the evacuation lumen to treat the tissue.
An apparatus to treat tissue at a surgical site of a patient, the apparatus comprising:
- a lens to view the tissue at the surgical site;
- an energy delivery probe comprising an energy source to emit an energy toward the tissue, the energy delivery probe comprising a longitudinal axis;
- and
- an elongate carrier to support the energy delivery probe, the elongate carrier configured to rotate the energy delivery probe to direct the energy to treat the tissue, the elongate carrier comprising an evacuation lumen extending to an opening to remove material from the surgical site;
- a probe configured to be inserted into the patient, the probe comprising an evacuation lumen to remove material from the surgical site, the evacuation lumen extending to the opening and wherein the probe extends beyond the energy delivery probe and at least partially defines the opening and wherein the probe comprises a portion with a recess sized and shaped to receive a distal end of the energy delivery probe to stabilize the energy delivery probe;
- wherein the elongate carrier supports the lens and is configured to translate the energy delivery probe and the lens together;
- wherein the energy delivery probe is configured to rotate the energy source around the longitudinal axis to a first position away from the opening of the evacuation lumen to treat the tissue and to rotate the energy source around the longitudinal axis to a second position toward the opening to remove the tissue, the second position opposite the first position.
