Tumours are, as a rule, removed surgically, by separating them from the tumour bed and finally rinsing the tumour bed with a cytotoxic fluid. The above represents two sequential working steps which prolongs surgery unnecessarily. The real disadvantage, however, is that the cytotoxic fluid in the post- operative treatment only reaches and kills superficial tumour cells. The use of a cytotoxic fluid by means of a high pressure liquid jet device is thus disclosed, for separation of the biological structure and concomitant treatment of the tumour bed.

En général, des tumeurs sont retirées par opération chirurgicale, en étant séparées du lit tumoral puis aspergées d'un liquide cytotoxique. Ce sont deux étapes qui nécessitent inutilement une opération chirurgicale. L'inconvénient essentiel réside dans le fait que, lors du traitement ultérieur, le liquide cytotoxique n'atteint et n'élimine que les cellules tumorales de surface. Ainsi, selon la présente invention, un liquide cytotoxique est utilisé pour séparer la structure biologique et traiter simultanément le lit tumoral au moyen d'un dispositif à jet de liquide haute pression.
