Uses |

A specialized form of vaginal speculum is the weighted speculum, which consists of a broad half tube which is bent at about a 90 degree angle, with the channel of the tube on the exterior side of the angle. One end of the tube has a roughly spherical metal weight surrounding the channel of the speculum. A weighted speculum is placed in the vagina during vaginal surgery with the patient in the lithotomy position. The weight holds the speculum in place and frees the surgeon's hands for other tasks. |

SpiraBrush CX |
An ectocervical biopsy brush used in place of punch forceps during colposcopy to collect a full transepithelial tissue sample. The resulting sample is then sent to a pathology lab for evaluation and diagnosis of cervical cancer. Abnormalities in these samples are similar to those seen in traditional cervical biopsies, and range from reactive squamous and glandular epithelial cells to overt invasive carcinoma.[4] |

This type of Long Curved Obstetric Forceps is invented by Sir Kedarnath Das. It is comparatively lighter and slightly shorter than its Western counterpart. But it is quite suited for the comparatively small pelvis and small baby for the Indian women. |
