| Abstract: | Accurate placement of the ablation needles is crucial to ensure complete liver tumour ablation in both microwave ablation (MWA) and irreversible electroporation (IRE). When using multiple needles, they must be placed parallel to each other and 15 mm apart. Currently, this is done freehand, which often requires the needles to be repositioned. Robots are being developed to place the needles more accurately. However, these robots are expensive. Therefore, there is a need for the design of a cheap, easy-to-use instrument. Hence, the main question is: ‘How to develop an instrument that simplifies the process of accurate placement of multiple ablation needles when treating liver tumours (up to 50 mm) with MWA or IRE compared to freehand needle placement?’ To answer this question the design cycle was used and completed three times. In each cycle, relevant background information was researched, and requirements were defined. Based on these, brainstorm sessions were held after which the possible designs were tested by evaluating them with the supervisors. This resulted in a final design that considered the requirements. However, it was not tested whether the target values are achieved. Future work is necessary to determine whether the instrument meets the requirements and whether it can be implemented in pratice. |
