Abstract :Surgeons use grippers for grasping and moving soft tissues during Laparoscopic surgery. The grasping jaws of these grippers have different toothed structures to prevent tissues from slipping. As a result of clamping tissues between grasping jaws, there is a risk of tissue damage. In this study, to eliminate this risk, a new Laparoscopic gripper that works on the Bernoulli principle and can lift tissues without clamping force was designed and produced, and its applicability tests were carried out with an experimental study. The gripper works by creating a vacuum with a high air flow rate with the Bernoulli principle between itself and the tissue. To not damage the lifted tissue by the strong air jet, a deflector was placed onto the center of the grasping surface to change the flowing direction of the air flowing in the axial direction. The study showed that a gripper working with the Bernoulli principle can be applicable to lift and move soft and flexible tissues without clamping force.
