Natural orifice bariatric procedure and apparatus for use therewith
View Patent ↗A method of performing a bariatric procedure through a natural body orifice is disclosed. The method comprises the step of providing a surgical instrument, comprising a handle portion, an elongated portion extending distally from the handle portion, and an end effector disposed adjacent a distal end of the elongated portion. The method also comprises the steps of inserting the surgical instrument through a natural body orifice of a patient such that the end effector is adjacent a portion of the patient's stomach, and using the surgical instrument to perform a surgical task.
1. A method of performing a bariatric procedure through a vaginal orifice, the method comprising:
providing a surgical instrument, the surgical instrument comprising:
a handle portion including an actuation mechanism disposed in mechanical cooperation therewith;
an elongated portion extending distally from the handle portion, including a length, and defining a longitudinal axis, the elongated portion being non-flexible along at least a majority of its length; and
an end effector disposed adjacent a distal end of the elongated portion and being disposed in mechanical cooperation therewith;
wherein the actuation mechanism controls at least one function of the end effector;
inserting the surgical instrument through a vaginal orifice of a patient such that the end effector is adjacent a portion of the patient's stomach;
using the surgical instrument to perform a surgical task; and
positioning a portion of the elongated portion adjacent the patient's pelvis and pivoting the surgical instrument while using the pelvis as a fulcrum.
2. The method of claim 1 , wherein the surgical instrument includes a length and wherein the length of the surgical instrument is between about 30 inches and about 45 inches.
3. The method of claim 1 , wherein the surgical instrument is a surgical stapling instrument.
4. The method of claim 3 , wherein the surgical stapling instrument includes a length and wherein the ratio of the length of the surgical stapling instrument to a diameter of the elongated portion is between about 63.5 and about 95.
5. The method of claim 1 , wherein the elongated portion of the surgical instrument is non-flexible along its entire length.
6. The method of claim 1 , wherein a distal portion of the elongated portion is flexible and wherein a proximal portion of the elongated portion is non-flexible.
7. The method of claim 1 , wherein the surgical task includes a vertical sleeve gastrectomy.
8. A method of performing a transvaginal bariatric procedure, the method comprising:
providing a surgical instrument, the surgical instrument comprising:
a handle portion;
an elongated portion extending distally from the handle portion, including a length, and defining a longitudinal axis, the elongated portion being non-flexible along at least a majority of its length; and
an end effector disposed adjacent a distal end of the elongated portion and being disposed in mechanical cooperation therewith;
creating an incision in the vaginal wall;
inserting the surgical instrument through the incision;
using the surgical instrument to perform a bariatric procedure; and
positioning a portion of the elongated portion adjacent the patient's pelvis and pivoting the surgical instrument while using the pelvis as a fulcrum.
9. The method of claim 8 , wherein the surgical instrument includes a length and wherein the length of the surgical instrument is between about 30 inches and about 45 inches.
10. The method of claim 8 , wherein the entire length of elongated portion of the surgical instrument is non-flexible.
11. The method of claim 8 , wherein the elongated portion of the surgical instrument is non-flexible along its entire length.
12. The method of claim 8 , wherein a distal portion of the elongated portion is flexible and wherein a proximal portion of the elongated portion is non-flexible.
13. The method of claim 8 , further comprising removing excised tissue through the incision in the vaginal wall.
14. A method of performing a bariatric procedure through a vaginal orifice, the method comprising:
providing a surgical instrument, the surgical instrument comprising:
a handle portion including an actuation mechanism disposed in mechanical cooperation therewith;
an elongated portion extending distally from the handle portion, including a length, and defining a longitudinal axis, the elongated portion being substantially rigid along at least a majority of its length; and
an end effector disposed adjacent a distal end of the elongated portion and being disposed in mechanical cooperation therewith;
wherein the actuation mechanism controls at least one function of the end effector;
inserting the surgical instrument through a vaginal orifice of a patient such that the end effector is adjacent a portion of the patient's stomach;
using the surgical instrument to perform a surgical task; and
positioning a portion of the elongated portion adjacent the patient's pelvis and pivoting the surgical instrument while using the pelvis as a fulcrum.
15. A method of performing a transvaginal bariatric procedure, the method comprising:
providing a surgical instrument, the surgical instrument comprising:
a handle portion;
an elongated portion extending distally from the handle portion, including a length, and defining a longitudinal axis, the elongated portion being substantially rigid along at least a majority of its length; and
an end effector disposed adjacent a distal end of the elongated portion and being disposed in mechanical cooperation therewith;
creating an incision in the vaginal wall;
inserting the surgical instrument through the incision;
using the surgical instrument to perform a bariatric procedure; and
positioning a portion of the elongated portion adjacent the patient's pelvis and pivoting the surgical instrument while using the pelvis as a fulcrum.
