During a robotic case, staff noticed the tip cover accessory for monopolar curved scissors are splitting at the seam.Staff went through 5 tips during the one case.One of them is missing a very small piece that became detached during the procedure.This piece was likely removed from the surgical site via suction.Without complete coverage on the monopolar scissors, patients are at risk for burns.The patient was not harmed as the covers were replaced when defects were noted.The procedure was completed as planned.Clinical engineering received 4 of these tip covers, all from the same lot #.Microscope images were obtained and demonstrate that the origin of each split is at the seam of the material.All pieces will be returned to intuitive surgical for failure analysis.Per site reporter: an rma will be issued and the device will be returned for failure analysis.We will monitor the analysis via the customer portal.
