Abstract

Cerrahlar, Laparoskopik cerrahi sırasında yumuşak dokuları tutmak ve hareket ettirmek için tutucular kullanmaktadır. Bu tutucuların kavrama çeneleri, dokuların kaymaması için değişik yapılarda dişli yapıya

sahiptirler. Dokuların tutucu çeneler arasında sıkıştırılması sonucunda doku hasarı riski oluşmaktadır. Bu çalışmada bu riskin ortadan kaldırılması için Bernoulli prensibi kullanılarak çalışan, dokuları sıkmadan

kaldırabilen yeni bir Laparoskopik tutucu tasarlanıp üretilerek deneysel çalışma ile uygulanabilirlik testleri yapılmıştır. Tutucu, doku ile arasında Bernoulli prensibi ile yüksek hava akış hızı ile vakum oluşturularak

çalışmaktadır. Kaldırılan dokuların kuvvetli hava jetinden zarar görmemesi için eksenel yönde akan havanın akış yönünü değiştirmek amacıyla tutucu yüzey merkezine deflektör yerleştirilmiştir. Çalışma, Bernoulli prensibi ile çalışan bir tutucunun yumuşak ve esnek dokuların sıkıştırılmadan kaldırılması ve hareketi için uygulanabileceğini göstermiştir.

Design and Feasibility Tests of A New Laparoscopic Gripper for Grasping Soft Tissues of Variable Shape Without Clamping Force

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.
