摘要：
Instruments and methods are described for performing hysteroscopy and/or combined hysteroscopy and endometrial biopsy. According to some embodiments, the handle, electronics and integrated display screen form a re-usable portion of the instrument while the fluid hub and cannula which includes a CMOS imaging module and LED lighting, form a single use portion of the instrument. The cannula is semi-flexible such that the operator can easily grasp the cannula at some intermediate point along the shaft (e.g. 5 inches from the distal tip) to bend and/or steer the cannula during use. According to some embodiments, the distal tip has a larger diameter than the shaft which has been found to improve fluid management during use in some applications.
