Research Project Cerrahi Aletlerle Yönlendirilebilen Robot Yardımlı Endoskop Kontrol Sistemi (neuroboscope)(2018) Berker, Mustafa; Işıkay, Ahmet İlkay; Çağıltay, NergizNeuRoboScope 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-Article Randomised Comparison Between Navigation and Non-Navigation Camera Control Performance in a Surgical Simulation Task Using a Haptic Device Interface(Wolters Kluwer Medknow Publications, 2026) Cagiltay, Nergiz Ercil; Topalli, Damla; Tuner, Emre; Berker, MustafaIntroduction:Navigation skills for controlling the camera in the surgical field are critical for many minimally invasive surgery (MIS) procedures. Currently, endoscopes lack integrated navigation aids, making camera control a challenging task. This experimental study aims to investigate the effect of navigation guidance on the performance of beginners.Patients and Methods:A custom computer-based simulation environment was developed for this study, featuring two conditions - one with navigation guidance and one without - focussed on a camera-cleaning task. Participants (64 beginners) were randomly assigned to one of these groups and used two haptic devices to simulate the endoscope and surgical tools.Results:Participants in the guided condition performed significantly better than those in the unguided condition. Notably, female participants completed the task in significantly less time under the guided condition compared to the unguided one.Conclusion:These findings suggest that incorporating navigation aids into endoscope interfaces could improve user performance, especially for beginners. Medical device manufacturers should consider adding navigation features to enhance usability. In addition, simulation-based instructional systems should integrate navigation aids to better support surgical training.Article Citation - WoS: 3Citation - Scopus: 5Technology-Enhanced Surgical Education: Attitudes and Perceptions of the Endoscopic Surgery Community in Turkey(Bmj Publishing Group, 2019) Cagiltay, Nergiz Ercil; Berker, MustafaThe education programme of surgery has unique problems. In this study, first, a literature review is conducted to cover the studies found in the literature reporting on the problems of surgical education. Additionally, a survey study is conducted with 31 participants, who are either currently enrolled in endoscopic surgery education programmes in Turkey or are experts in the field. Supportively semistructured individual interviews are also conducted with five participants. These data are collected to better understand the instructional methods being used, their problems and the participants' preferred methods to be used. Additionally, the participants' attitudes are also investigated regarding the use of new technologies to enhance the current education programmes. The results indicate that, in Turkey, surgical education programmes are still mostly offered in traditional ways while other educational methods are used in an extremely limited manner. In general, the authors emphasise that more research needs to be conducted to better understand the characteristics of the medical students and develop standards for surgical education programmes, educational tools specific for related surgical domains and guidelines for the curriculum integration. The results of this study aimed to guide the instructional system designers for the endoscopic surgery education programmes.
