  • Richter, Berna I.; Ostermeier, Sven; Turger, Anke; Denkena, Berend; Hurschler, Christof (London : BioMed Central Ltd., 2010)
    Background: Material wear testing is an important technique in the development and evaluation of materials for use in implant for total knee arthroplasty. Since a knee joint induces a complex rolling-gliding movement, ...
  • Amanov, E.; Nguyen, T.-D.; Burgner-Kahrs, Jessica (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Tubular continuum robots, which are composed of multiple concentric, precurved, elastic tubes, provide more dexterity than traditional surgical instruments at the same diameter. The tubes can be precurved such that the ...
  • Wirz, Raul; Lathrop, Ray A.; Godage, Isuru S.; Burgner-Kahrs, Jessica; Russell, Paul T.; Webster, Robert J. (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Anecdotally, surgeons sometimes observe large errors when using image guidance in endonasal surgery. We hypothesize that one contributing factor is the possibility that operating room personnel might accidentally bump the ...
  • Schoob, Andreas; Lekon, Stefan; Kundrat, Dennis; Kahrs, Lüder Alexander; Mattos, Leonardo S.; Ortmaier, Tobias (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Recent research has revealed that incision planning in laser surgery deploying stylus and tablet outperforms stateof-the-art micro-manipulator-based laser control. Providing more detailed quantitation regarding that approach, ...
  • Tinne, Nadine; Knoop, Gesche; Kallweit, Nicole; Veith, Sonja; Bleeker, Sebastian; Lubatschowski, Holger; Krüger, Alexander; Ripken, Tammo (Bellingham, WA : SPIE - International Society for Optical Engineering, 2014)
    We present a time-resolved photographic analysis of the pulse-to-pulse interaction. In particular, we studied the influence of the cavitation bubble induced by a fs-pulse on the optical focusing of the consecutive pulse ...
  • Fellmann, Carolin; Kashi, Daryoush; Burgner-Kahrs, Jessica (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    For those minimally invasive surgery where conventional surgical instruments cannot reach the surgical site due to their straight structure and rigidity, concentric tube continuum robots are a promising technology because ...
  • Erdmann, Nina; Bondarenko, Alexandr; Hewicker-Trautwein, Marion; Angrisani, Nina; Reifenrath, Janin; Lucas, Arne; Meyer-Lindenberg, Andrea (London : BioMed Central Ltd., 2010)
    Background: Recent studies have shown the potential suitability of magnesium alloys as biodegradable implants. The aim of the present study was to compare the soft tissue biocompatibility of MgCa0.8 and commonly used ...
  • Brand, Stephan; Bauer, Michael; Petri, Maximilian; Schrader, Julian; Maier, Hans Jürgen; Krettek, Christian; Hassel, Thomas (London : SAGE Publications Ltd., 2016)
    Treatment of periprosthetic femur fractures after total hip arthroplasty remains a major challenge in orthopedic surgery. Recently, a novel surgical technique using intraprosthetic screw fixation has been suggested. The ...
  • Vollmann, Benjamin; Müller, Samuel; Kundrat, Dennis; Ortmaier, Tobias; Kahrs, Lüder Alexander (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    This work proposes new methods for a microstereotactic frame based on bone cement fixation. Microstereotactic frames are under investigation for minimal invasive temporal bone surgery, e.g. cochlear implantation, or for ...
  • Grau, Michael; Seiler, Christian; Roland, Laura; Matena, Julia; Windhövel, Claudia; Teske, Michael; Escobar, Hugo Murua; Lüpke, Matthias; Seifert, Hermann; Gellrich, Nils-Claudius; Haferkamp, Heinz; Nolte, Ingo (Basel : MDPI AG, 2017)
    Metallic biomaterials are widely used in maxillofacial surgery. While titanium is presumed to be the gold standard, magnesium-based implants are a current topic of interest and investigation due to their biocompatible, ...
  • Bergmeier, Jan; Fast, Jacob Friedemann; Ortmaier, Tobias; Kahrs, Lüder Alexander (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Image-to-physical registration based on volumetric data like computed tomography on the one side and intraoperative endoscopic images on the other side is an important method for various surgical applications. In this ...
  • Baron, S.; Eilers, H.; Munske, B.; Toennies, J.L.; Balachandran, R.; Labadie, R.F.; Ortmaier, T.; Webster, R.J. (London : SAGE Publications Ltd., 2010)
    Image-guided robots have been widely used for bone shaping and percutaneous access to interventional sites. However, due to high-accuracy requirements and proximity to sensitive nerves and brain tissues, the adoption of ...
  • Schoob, Andreas; Kundrat, Dennis; Kahrs, Lüder Alexander; Ortmaier, Tobias (Amsterdam : Elsevier BV, 2017)
    Recent research has revealed that image-based methods can enhance accuracy and safety in laser microsurgery. In this study, non-rigid tracking using surgical stereo imaging and its application to laser ablation is discussed. ...
  • Lubatschowski, Holger (Amsterdam : Elsevier B.V., 2010)
    Ultrafast laser pulses have become a promising tool for microsurgery of the eye. Due to the low energy threshold, side effects are limited to the micrometer range This precision enables the use of ultrashort laser pulses ...
  • Ilango, Shivaraman; Knöchelmann, Marvin; Kahrs, Lüder Alexander; Wolf, Alexander; Ortmaier, Tobias; Lachmayer, Roland (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    Projector based augmented reality serves as an alternate visual guidance tool for surgeons when performing complicated open surgeries. In projector based augmented reality, image overlay projection is a technique that ...
