Research Project Cerrahi Aletlerle Yönlendirilebilen Robot Yardımlı Endoskop Kontrol Sistemi (neuroboscope)(2018) Berker, Mustafa; Işıkay, Ahmet İlkay; Çağıltay, Nergiz; Isikay, IlkayNeuRoboScope Projesi ile hipofiz bezinden kaynaklanan tümörlerin minimal invaziv cerrahisi sırasında, bu islemde kullanılan görüntüleme aracını (endoskop) cerrahın istedigi sekilde yönlendirilmesine yarayan özel bir robotik sistem gelistirmesi amaçlanmıstır. Ameliyatı gerçeklestiren cerrahın -biri endoskop olmak üzere- üç adet ameliyat aletini aynı anda kullanması hedeflenmistir. Önerilen sistemde, giyilebilir bir ana kumanda sistemi ile cerrahın el hareketleri istedigi anda algılanarak ve uygun bir sekilde islenerek endoskopu yönlendiren robot kola hareket bilgisini ulastırması amaçlanmıstır. Bu sayede, cerrah iki eliyle farklı cerrahi aletleri kullanırken ameliyat boyunca istedigi zaman operasyona ara vermeden endoskopu yönlendirebilmesi hedeflenmistir. Bu kritik ameliyat için, cerrahi operasyonun performansının ve verimliliginin arttırılması ve ameliyat süresinin kısalması önemlidir. Bu amaca ulasmak için robotik ameliyat sisteminin gereksinimleri cerrah ekibi ile yapılan ön-prototip testleri ve toplantılarla belirlenmis; robot sisteminin mekanik, elektronik ve yazılımsal tasarımları gerçeklesitirilmis; tasarım dogrulama gerek bilesenler üzerinde gerekse alt-sistemler için yapılmıs; ilk nesil prototipler üretilip üzerlerinde yapılan testler neticesinde tasarım degisiklikleri islenerek ikinci nesil prototipler üretilmis; simülatör ve kafatası maketi üzerinde gelistirilen sistemin performansı ve kullanılabilirligi test edilmistir. Cerrahla robotun aynı anda hasta üzerinde ameliyatı gerçeklestirdigi ve cerrahın gerekli gördügü durumlarda robot ile fiziksel etkilesime geçerek beraber çalıstıgı bu sistem, ameliyat robotu sınıflandırmasında isbirlikçi ameliyat robotu olarak yeni bir kategoriye yerlesmistir.Research Project Endoskopik Cerrahisi Eğitim (ece)'inde Teknoloji ile Zenginleştirilmiş Ortamların Etkinliğinin Araştırılması(2015) Çağıltay, Nergiz; Şengül, Gökhan; Özçelik, Erol; Berker, Mustafa; Işıkay, Ahmet İlkay; Maraş, Hadi Hakan; Isikay, Ilkay-Conference Object Simulations for Surgical Education: a Case Study for Endoneurosurgery(Iated-int Assoc Technology Education A& development, 2015) Berker, Mustafa; Cagiltay, Nergiz Ercil; Isikay, IlkayToday, introduction of the microscope and later the extensive use of the video camera have changed the way operations are performed which have replaced the direct vision by a video image. These types of surgical techniques are generally called as minimal invasive surgery (MIS). Laparoscopic surgery and endoscopic surgery fall in this category. These new technologies require some additional skills to be gained during the surgical education and training programs. Most of the traditional surgical training takes place in the operating theater under the supervision of an experienced surgeon which does not allow any try-and-error type of learning, and does not tolerate errors. Hence, alternative educational methods by providing try-and-error type of learning are a critical for medical education. This study presents a simulation environment developed specifically for the pituitary surgery operations. The simulation environment composed of two main parts: the skill-based education and the procedure-based education for the novice surgeons. This study shows the design and implementation of educational modules developed to provide try-and-error type of educational environments as a case study on pituitary surgery operations.Article Citation - WoS: 13Citation - Scopus: 14The Effect of Training, Used-Hand, and Experience on Endoscopic Surgery Skills in an Educational Computer-Based Simulation Environment (ece) for Endoneurosurgery Training(Sage Publications inc, 2019) Cagiltay, Nergiz Ercil; Ozcelik, Erol; Isikay, Ilkay; Hanalioglu, Sahin; Suslu, Ahmet E.; Yucel, Taskin; Berker, MustafaToday, virtual simulation environments create alternative hands-on practice opportunities for surgical training. In order to increase the potential benefits of such environments, it is critical to understand the factors that influence them. This study was conducted to determine the effects of training, used-hand, and experience, as well as the interactions between these variables, on endoscopic surgery skills in an educational computer-based surgical simulation environment. A 2-hour computer-based endoneurosurgery simulation training module was developed for this study. Thirty-one novice- and intermediate-level resident surgeons from the departments of neurosurgery and ear, nose, and throat participated in this experimental study. The results suggest that a 2-hour training during a 2-month period through computer-based simulation environment improves the surgical skills of the residents in both-hand tasks, which is necessary for endoscopic surgical procedures but not in dominant hand tasks. Based on the results of this study, it can be concluded that computer-based simulation environments potentially improve surgical skills; however, the scenarios for such training modules need to consider especially the bimanual coordination of hands and should be regularly adapted to the individual skill levels and progresses.
