FIELD: medicine.
SUBSTANCE: group of inventions relates to medicine. Phacoemulsification tip comprises: a body having proximal and distal ends; a channel having proximal and distal ends; Pressure transducer housing comprises path for irrigation fluid passing through pressure transducer housing. Pressure transducer housing comprises joint with seal at one end of pressure sensor housing, wherein end with joint with pressure sensor housing seal is connected to channel proximal end such that channel irrigation channel passage is in fluid communication with housing irrigation path pressure sensor. Channel is connected to housing so that proximal end of channel is located on proximal end of housing, and distal end of channel is located near distal end of housing, besides, channel has passage for irrigation fluid. Second version of the phacoemulsification tip further comprises a pressure sensor assembly having a flexible printed circuit board, wherein a pressure sensor is connected to the flexible printed-circuit board, wherein pressure sensor is located in cavity of housing of pressure sensor, and pressure sensor measures liquid pressure in path for irrigation fluid.
EFFECT: use of this group of inventions enables to minimize delay in tracking eye pressure.
