Robotic phrenic nerve harvest: a feasibility study in a pig model

Area of Science:

• Minimally Invasive Surgery
• Neurosurgery
• Surgical Robotics

Background:

• The phrenic nerve is crucial for diaphragmatic function.
• Harvesting the phrenic nerve is a potential strategy for brachial plexus reconstruction.
• Minimally invasive techniques may offer advantages over traditional open surgery.

Purpose of the Study:

• To assess the feasibility of robotic phrenic nerve harvest.
• To evaluate the safety and efficiency of the procedure in a preclinical model.
• To explore the potential clinical applications of robot-assisted phrenic nerve harvesting.

Main Methods:

• A Da Vinci S surgical robot was utilized.
• Three ports were placed in the left chest of a pig model.
• The phrenic nerve was transected distally at its diaphragmatic entry point.

Main Results:

• Robotic phrenic nerve harvest was successfully completed in 45 minutes.
• The procedure was performed without major intraoperative complications.
• Key robotic advantages include motion scaling, tremor elimination, and enhanced dexterity.

Conclusions:

• Robotic phrenic nerve harvest is a feasible and safe procedure in a porcine model.
• Robot-assisted neurolysis offers potential benefits for phrenic nerve harvesting.
• This technique may prove clinically valuable for brachial plexus reconstruction.
