Surgical devices and methods for bariatric and gastroesophageal surgery
Disclosed are various embodiments for improved surgical devices and methods of using the same in connection with bariatric and gastroesophageal surgery. The present disclosure includes a lighted bougie device that can include an elongate member and a light source. The light source can be configured to emit near-infrared light. The light source can also be positioned about the bougie such that light emitted from the light source illuminates along a portion of the bougie.
1. A lighted device for use in a surgical procedure, the lighted device comprising:
an elongate member having a distal end for inserting into an operative field of a patient and having a proximal end; and
a handle coupled to the proximal end of the elongate member, the handle having a larger exterior diameter than an exterior diameter of the elongate member; and
a plurality of light sources disposed along the elongate member and configured to emit light in a first wavelength range and a second wavelength range, wherein the plurality of light sources is disposed along at least 50% of the elongated member wherein:
the light emitted by the plurality of light sources in the first wavelength range is able to transmit through one or more first tissues of the patient but unable to transmit through one or more second tissues of the patient;
the light emitted by the plurality of light sources in the second wavelength range is able to transmit through both the one or more first tissues and the one or more second tissues of the patient; and
each respective light source in at least a subset of the plurality of light sources is located at a corresponding distance in a plurality of distances relative to the distal end of the elongate member and adjacent light sources in at least the subset of the plurality of light sources are spaced apart along a length direction of the elongated member at a predetermined interval of between 0.5 cm and 5 cm, thereby allowing a user of the lighted device to locate light sources on the elongate member in the operative field of the patient and use the elongated member for one or more intraoperative measurements by detecting light emitted by at least the subset of the plurality of light sources in the first and second wavelength ranges and transmitted through the one or more first tissues of the patient, the one or more second tissues of the patient or both and to use the elongated member and the located light sources on the elongated member in the operative field of the patient as a ruler for one or more intraoperative measurements.
2. The lighted device of claim 1 , wherein the plurality of light sources comprises at least one LED light, at least one optic fiber, a polymer containing a near infrared fluorescent material, or any combination thereof.
3. The lighted device of claim 1 , wherein the operative field is a gastrointestinal tract of the patient and the light emitted from the plurality of light sources is detectable by a camera positioned outside of the gastrointestinal tract.
4. The lighted device of claim 3 , wherein the camera is configured to detect the light in the first wavelength range, in the second wavelength range, or both.
5. The lighted device of claim 1 , wherein the elongated member comprises a suction channel, and one or more apertures extending from an exterior surface of the elongate member into the suction channel.
6. The lighted device of claim 1 , wherein the elongate member is a bougie configured to be inserted into an esophagus and/or a stomach of the patient.
7. The lighted device of claim 1 , wherein each of the plurality of light sources is configured to emit light in the first wavelength range and the second wavelength range.
8. The lighted device of claim 1 , wherein the first and second wavelength ranges are two distinct wavelength ranges.
9. The lighted device of claim 8 , wherein the first wavelength range is a white light range and the second wavelength range is a near-infrared light range.
10. The lighted device of claim 9 , wherein the first wavelength range is about 400 nm to about 650 nm.
11. The lighted device of claim 9 , wherein the second wavelength range is about 700 nm to about 1300 nm, or about 700 nm to about 850 nm.
12. The lighted device of claim 1 , wherein a first tissue in the one or more first tissues is thinner than a second tissue in the one or more second tissues.
13. The lighted device of claim 1 , wherein the plurality of light sources is operated to alternately emit the light in the first wavelength range and in the second wavelength range.
14. The lighted device of claim 13 , wherein the elongate member is a bougie configured to be inserted into a stomach of the patient, and the light emitted by the plurality of light sources allows visualization of an outside of the stomach and the bougie in the stomach of the patient.
15. The lighted device of claim 1 , wherein a measurement in the one or more intraoperative measurements is selected from the group consisting of:
a measurement of a length of a Heller Myotomy during a laparoscopic or robotic Heller operation;
a measurement of a distance between an esophageal hiatus and a gastric angle of His during a laparoscopic or robotic hiatal hernia repair;
a measurement of a length of a gastric pouch in laparoscopic or robotic bypass surgery; length of gastric sleeve during a laparoscopic or robotic sleeve gastrectomy; and
a measurement to localize gastric and lower esophageal tumors during laparoscopic or robotic operations.
16. The lighted device of claim 15 , wherein the measurement in the one or more intraoperative measurements is performed during a surgery taking place in a rectum, colon, upper and lower gastrointestinal tract, urologic organ, or gynecological organ.
17. The lighted device of claim 1 , wherein the lighted device is configured to be used as a guide during the medical procedure.
18. The lighted device of claim 1 , wherein the lighted device is configured to be used for a laparoscopic or robotic surgery.
19. The lighted device of claim 1 , wherein a first respective light source in at least the subset of the plurality of light sources is located at a first corresponding distance relative to the distal end of the elongate member and a second respective light source in at least the subset of the plurality of light sources is located at a second corresponding distance relative to the distal end of the elongate member that is different than the first corresponding distance.
20. The lighted device of claim 1 , wherein the elongate member has a diameter of 34 French, 36 French, 38 French, or 40 French.
21. The lighted device of claim 1 , wherein the elongate member has a length of about 32 inches.
22. The lighted device of claim 1 , wherein the plurality of light sources comprises at least 10 individual light sources.
23. The lighted device of claim 1 , wherein adjacent light sources in at least the subset of the plurality of light sources are spaced apart evenly along the length direction of the elongated member.
