Surgical Technologies
Surgical Technologies covers the development, design, testing and analysis of implants, surgical instruments and medical devices. In cooperation with our industrial partners and leading research clinics, we develop new implants and test procedures. Thereby, we count on most modern laboratory infrastructure (current testing machines and industrial robots) as well as functional simulators developed in-house.
The laboratory has ISO 17025 Type C accreditation for the development of test procedures for endoprostheses, implants & traumatology products.
For analysis, we have a wide range of measurement technologies as force sensors, strain gauges, acceleration sensors and digital image correlation

OsteoFusion: Highly osteoconductive and fast incorporating ceramic implant solutions for Sports Medicine (and Orthopedics)
In Sports Medicine, a faster return to full activity, a better cost-benefit ratio, and maximized patient comfort are paramount. OsteoFusion provides a solution with an innovative ceramic implant that transforms into bone being anchored by ultrasonic liquefaction of a fiber-reinforced biocomposite. ...

Mechanobiological plastic model
Plastics are experiencing increased interest in medical technology. Due to their mechanical properties, plastics correspond more closely to human tissue than metallic materials such as titanium or cobalt-chromium. The so-called mechanobiology of human soft tissue, especially cartilage and intervertebral discs, is ...

Robot-based experimental in vitro studies to evaluate two surgical techniques for a meniscal lesion with respect to knee kinematics
In this project, the following hypotheses will be investigated with experimental robot-based in vitro tests on human leg specimens 1) Ramp lesion of the posterior horn of the medial meniscus leads to increased anterior translation and rotational instability in a knee with an ACL rupture. 2) In a knee with an ACL ...

Influence of additional weight carrying on load-induced changes in glenohumeral translation in patients with rotator cuff tear - a translational approach
This project aims to explore human shoulder biomechanics using a functional shoulder model. The experimental tests are compared with subject measurements for a better characterization of the muscle and joint forces acting on the shoulder.

Development of a unicondylar knee joint prosthesis with physiological kinematics
This project has two objectives: 1. to optimise the surface geometry of an existing unicondylar knee prosthesis in order to enable natural knee kinematic 2. to model and validate a generally valid parameter model of the knee ligaments in FEA. In the development process, both experimental robot-supported tests on ...
