Blunt dissection in laparoscopic surgery is made difficult by the long length of the instruments, impaired haptic feedback (“sense of feel”), and restricted angle of approach. As such, we believe Differential Dissection will have greatest impact in laparoscopic surgery.

The Model DD-Lap is being designed with a 5 mm diameter shaft and different lengths (27 cm to 35 cm).

The DD-Lap has been used successfully by over 50 surgeons in a broad range of surgical procedures: adhesiolysis; lymphadenectomy; cholecystectomy; mesorectal excision and colectomy; peritoneal takedown and inguinal dissection for TAPP and TEP hernia repair; TAR hernia repair; hernia mesh removal; mobilization of veins, arteries, nerves, ureter, urethra, Fallopians, and urinary bladder; partial and complete nephrectomy; mobilization & skeletonization of the gastroepiploic and other gastric arteries; and many others. Surgeons suggest Differential Dissection technology would also be helpful in a broad range of other procedures, including organ transplant (lung, heart, liver, kidney), lung decortication, myomectomy (uterine fibroids), hysterectomy, cystectomy, prostatectomy, breast lumpectomy, subcutaneous tunneling for lead placement, esophagectomy, and others.

The Model DD-Lap has also been designed to be highly multi-functional to alleviate the disruption caused by instrument changes during laparoscopy. The Model DD-Lap, with an optional Suction/Irrigation/Smoke Evacuation Module (SISE) combines 6 functions in a single shaft:

1. Blunt dissection (Differential Dissection)
2. Electro-cut (via an extendable electro-hook)
3. Electro-coagulation (via the same hook)
4. Suction
5. Irrigation
6. Smoke evacuation

All functions can be controlled easily with one hand. Surgeons in preclinical labs (cadaver and live porcine) have completed multiple procedures in a row without a single instrument change.

Additionally, electrosurgery, suction, irrigation, and smoke evacuation don’t require expensive, dedicated pumps or controllers. Electrosurgery connects to commonly used electrogenerators. Suction and smoke evacuation connect to a standard suction chamber attached to house vacuum. Irrigation attaches to a bag on an IV pole via a bag stick. No multi-thousand dollar units. No additional equipment and lighted control panels in the already crowded OR. No additional load on medical engineering.
