GYNAECOLOGICAL SAMPLERS

摘要

Known endometrial samplers has an outer catheter and an inner plunger slidable within the catheter. The catheter has a single circular side opening close to its tip through which samples are aspirated into the catheter. In the present invention the catheter has two two side openings located diametrically opposite one another close to the tip, the side openings being elongate along the axis of the catheter. The catheter also has a coaxial opening at its tip. The tip of the plunger projects into the tip opening to form a smooth surface to the sampler. An O-ring seal on the plunger is located rearwardly of the side openings so that suction is applied to both the side openings and the tip opening when the plunger is pulled rearwardly.
