In the surgery of the pituitary gland and other related areas of the skull base, the endoscopic endonasal surgery has established oneself as today's operation method. Although the surgeon is able to look around corners with the aid of an endoscope, the dissection in these areas is limited. Current suction devices are limited in their size, shape, bending and prone to kinking because of the narrow suction channel. The work with such inadequate instruments increase the risk of life-threatening complications, prolong the operation and limit the quality of a complete tumor resection. The ideal suction device would be adaptable to numerous surgery situations, easy to bend, maintain its lumen, adequate in their ratio of rigidity and formability, ergonomic and reformable to its original shape. In the following bachelor thesis, it is shown that this can be achieved with a suction device with shape memory alloy. After the development of a comfortable hand sample, the suction device went into preparation and a risk analysis was performed. The results of the evaluation process are reductions in operative risk, time and cost if this bendable suction device would be applied. Therefore, approval for the international market should be sought, to provide an opportunity for safer and more effective surgical procedures.
