“…To achieve such accuracy, a robotically assisted procedure which overcomes the inability to precisely position the surgical drill using hand held instruments [5] was suggested [6][7][8][9][10]. The safe and effective conduction of an image guided, robotically assisted DCA procedure, strongly relies on the quality of the surgical plan and the accuracy at which the surgical plan can be registered to the physical patient intraoperatively.…”

Abstract:Purpose: For the facilitation of minimally invasive robotically performed direct cochlea access (DCA) procedure, a surgical planning tool which enables the surgeon to define landmarks for patient-to-image registration, identify the necessary anatomical structures and define a safe DCA trajectory using patient image data (typically computed tomography (CT) or cone beam CT (CBCT)) is required. To this end, a dedicated end-to-end software planning system for the planning of DCA procedures that addresses current deficiencies has been developed.

“…Different approaches for bone attached platforms for interventions around the head already exist and some of them are already commercialized or are under clinical testing [1][2][3] . Target objects are the cochlea, granuloma in the temporal bone, or anatomical structures inside the brain during interventions for deep brain stimulation.…”

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 deep brain stimulation, where products are already on the market. The correct pose of the microstereotactic frame is either adjusted outside or inside the operating room and the frame is used for e.g. drill or electrode guidance. We present a patientspecific, disposable frame that allows intraoperative, sterile pose-setting. Key idea of our approach is bone cement between two plates that cures while the plates are positioned with a mechatronics system in the desired pose. This paper includes new designs of microstereotactic frames, a system for alignment and first measurements to analyze accuracy and applicable load.

Abstract. Principles of uncertainty evaluation for measurement processes and capability studies for production processes are established in many producing enterprises to ensure capable processes. Together with further quality management methods this allows to estimate and minimize the risk of producing defective parts and of taking wrong decisions about the part's conformity with its specification. This understanding is also desirable for a completely different field, for medical surgery. To quantify the risk of minimally invasive surgery for an individual patient, principles of metrology and production engineering are transferred to the medical domain and are exemplarily applied to minimally invasive surgery at the inner ear. It is shown how the main influencing factors, the uncertainty of the imaging and image processing and the uncertainty of the navigation process of the surgical instrument can be estimated with methods from production metrology. Furthermore, it is shown how these factors contribute to quantifying the patient's risk of a specific surgery by contributing to a therapeutic risk indicator (TRI).Abstract. Les principes et méthodes pour estimer l'incertitude de mesure et l'aptitude de procès de manufacture ont été établis dans beaucoup d'entreprises pour obtenir des procès capables. En combinaison avec d'autres méthodes de gestion de qualité, le risque de fabriquer des pièces endommagées et de prendre une décision non-fondée concernant la qualité d'une pièce peut être réduit. Ce concept est aussi souhaitable pour un autre domaine : les opérations chirurgicales mini-invasives. Les principes de métrologie et de technique de production sont transférés dans le domaine médical pour quantifier le risque d'une opération mini-invasive pour un patient, par exemple d'une opération mini-invasive de l'oreille interne. Ce travail montre comment les facteurs principaux, l'incertitude d'imagerie et l'incertitude de naviguer les instruments chirurgicaux, peuvent être estimés avec les principes de métrologie manufactures. En plus, cela montre comment ces facteurs contribuent à quantifier le risque d'une opération mini-invasive et à l'index thérapeutique de risque (TRI).
