A method or device for illuminating the biliary tree utilizing differential light absorption of biliary ducts and surrounding tissues (BioDesign) (Hadasit)
- 总结
- Need:
Laparoscopic cholecystectomy is a minimally invasive procedure for gallbladder removal surgery. Over 750,000 cholecystectomy procedures are carried out each year in the United States alone. The most serious complication is bile duct injury, which occurs in 1 in every 200 surgeries, primarily due to misidentification of biliary anatomy.
Current solutions utilize intravascular injection of fluorescent dyes, ultrasound, or X-ray images to visualize the bile duct anatomy, significantly increasing the complexity of the laparoscopic procedure, and therefore their use is seldom.
Innovation:
Our solution utilizes back-lit illumination of the biliary tree. By using a solid-state fiber optic which is inserted into a clip applier or a standard clamp, light is preferentially absorbed by bile acids. Bile absorbs visible light at a wavelength range of 600-700 nm, providing significant contrast over the surrounding tissue without changing the standard laparoscopic procedure.
Indication / Application:
Minimally Invasive Surgery
- 技术优势
- Real time visualization of the biliary tree
Enhanced procedure safety
No pre-op preparation or change in surgical technique are required
- 其他
- Proof of concept achieved in small animal model
