METHOD OF PUNCTURE BIOPSY OF ORBIT NEOPLASM Russian patent published in 2010 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to ophthalmology, and can be used in diagnostics of tumours and tumour-like diseases of orbit. Computer and/or magnetic resonance tomography of orbit with further introduction of biopsy needle into orbit and orbit neoplasm is performed. For this purpose primarily three-dimensional model of patient's orbit is created, after that carried out is modelling of course of puncture biopsy of orbit neoplasm on three-dimensional orbit model (TOM), during which location of point of biopsy needle entrance into TOM is determined, angle of biopsy needle inclination and depth of biopsy needle introduction into TOM are measured. After that points are transferred from TOM to patient's eye orbit. Biopsy needle is introduced into patient's orbit and into orbit neoplasm in point of entrance, determined on TOM, at angle between introduce biopsy needle and perpendicular, determined on TOM, to the depth of biopsy needle introduction into orbit, determined on TOM, after which, sampling of biopsy material is performed.

EFFECT: method allows to increase accuracy of introduction of biopsy needle into orbit and orbit neoplasm and reduce trauma of intraorbital structures in course of puncture biopsy.
