ABSTRACT:
An irrigating fluid from irrigating bottle (10) is supplied to the eye under operation through the tip of US handpiece (2) and sucked in through flexible aspirating tube (16) together with the residue in the eye. Peristaltic pump (20) sucks in the liquefied residue in the eye by means of rollers (21) which compress the aspirating tube (16) to collapse as they rotate. Block (28) is provided just prior to the point where the rollers (21) start compressing the aspirating tube (16) to collapse, such that the aspirating tube (16) is flattened while securing the aspirating path in the tube (16) as it is held between the block (28) and tube receptacle (25). The change in the capacity of the aspirating tube (16) which occurs when the rollers (21) compress the aspirating tube (16) is limited so that only a small volume of the liquefied residue will flow back. Thus, it is possible to reduce the pulsation from aspiration, thereby ensuring consistent rate of inflow.
