The DD-Lap has 3 functions (blunt, electro-cut, electrocautery) and the optional Suction-Irrigation Module (SIM) adds 3 more (suction, irrigation, smoke evacuation) for a total of 6 functions in a single, 5-mm-diameter shaft instrument. All are easily accessed with one hand, permitting rapid switch between functions, as demonstrated here. Note that the DD-Lap connects to standard electrogenerators, and the SIM connects simply to a bag and to house vacuum – no expensive, proprietary capital items are needed. (Total time = 0:30)
Smoke Reduction
Smoke evacuation with the Suction-Irrigation module provides a smoke-free surgical field without needing an expensive smoke handler. (Total time = 2:10)
Mesorectal Excision
Laparoscopic mesorectal excision in a human cadaver demonstrating the use of Differential Dissection and the Differential Dissector’s extendable monopolar hook. The result is a faster dissection that spares and skeletonizes vessels and nerves for safe electrosurgical division. (Total time = 3:14)
Mesh Removal
The DD-Lap is used to remove a large polypropylene mesh. It was placed 2 weeks earlier, and peritoneal ingrowth was extensive; nevertheless, the DD-Lap quickly removed the mesh, leaving the peritoneum with little trauma. (Total time = 3:03)
DD vs Electric Scissors
The DD-Lap is compared to monopolar scissors for removal of hernia mesh in a live pig lab. The DD-Lap was dramatically faster and far less traumatic. (Total time = 5:54)
Difficult Cholecystectomy with the DD-Lap
The DD-Lap is used on a human cadaver to safely complete a difficult cholecystectomy – scarred up, fatty field with adhesions holding the small intestine over the zone of safety, completely obscuring the view. The surgeon safely releases the intestine, exposes the critical anatomy, and completes the procedure without perforating the gall bladder, entering the liver bed, or traumatizing the cystic duct. (Total time = 7:56)
Cholecystectomy
Cholecystectomy in a live pig with almost no electrosurgery. The liver bed is pink and uncharred at the end. (Total time = 2:13)
Adhesiolysis
The DD-Lap is used to lyse a large, mature adhesion in a human cadaver between the liver and the abdominal wall. (Total time = 2:21)
Bowel Adhesiolysis
The DD-Lap is used to release a bowel stuck to the abdominal wall in a live pig lab. The bowel was not injured. The adhesion was caused by placement of polypropylene mesh (peritoneal overlay) 2 weeks earlier. (Total time = 4:10)
Spleen Adhesiolysis
The spleen in a pig is very large. Here, it is stuck to polypropylene mesh placed as an overlay on the peritoneum 2 weeks earlier. The spleen is removed with almost no bleeding and almost no cautery. (Total time = 3:34)
TAPP Hernia Repair with the DD-Lap
The DD-Lap is used on a human cadaver to perform peritoneal takedown for a TAPP hernia repair procedure and then to dissect the inguinal anatomy. Here, the surgeon deliberately tries to harm the inguinal anatomy and can not. (Total time = 2:58)
Peritoneal Takedown
The DD-Lap is used to take down the peritoneum in a live pig lab, as shown in the video above for the human cadaver. Note that while the peritoneum of the pig is much more fragile than in humans, the DD-Lap takes it down without any holes or other trauma. (Total time = 0:52)
