A surgeon's precision is paramount to have an effective surgery. The SOMATEX® localisation set S.-R. assists surgeons to find the right spots before operation starts. The puncture needle (2-part / 20G) comes with a sharp echogenic tipm while the rigid hook firmly holds its position so that there is no excess shifting or moving that could potentially cause the accidental severing. The set helps to marking our preoperative areas that cannot be touched as well as mammary lesions. With this it makes it easier for the surgeon to locate the areas with precision. There is a fixing part that makes it easy for wire place so that excess movement does not affect the security and safety of the area.
