Instrument
Uses
Speculum
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.
Auvard's speculum
Speculum used in standard vaginal procedures.
Cusco's speculum
Bivalved self retaining speculum. Its advantage over Sim's speculum is that no assistance is required to hold it in place. Hence, minor procedures like papsmear, IUCD insertions can be performed independently. Its disadvantage is the limited visualization of vagina walls.

Scalpel
Vulsellum
Single toothed vulsellum
Multiple toothed vulsellum
Giant vulsellum
Mucus sucker - disposable or metal
Forceps
Long straight hemostatic forceps
Allis tissue forceps
Babcock's forceps
Lanes tissue forceps
Uterus holding forceps
Sponge holding forceps
Kocher's artery forceps
Kocher's forceps with toothed jaws [3]
Green-Armytage hemostatic forceps
- Can be used during Myomectomy.
Willet's scalp traction forceps
Ovum forceps
Punch biopsy forceps
- Used in Premalignant lesions of the cervix. Its provides a specimen.
Uterine dressing forceps
FemCerv Endocervical Sampler
The FDA cleared disposable FemCerv endocervical Sampler can be used to biopsy the endocervical canal during colposcopyor the evaluation of abnormal uterine bleeding. FemCerv is intended to collect a 360° Endocervical tissue sample for histological evaluation. After collection the device is closed to contain and protect the sample within the patented collection chamber. To release the tissue sample the device is opened and the tip swished in a vial of fixative. The sample is then sent to the pathology lab for processing..
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]
SoftECC
The FDA Compliant disposable Soft-ECC endocervical curette can be used to biopsy the endocervical canal during colposcopy or the evaluation of abnormal uterine bleeding. Unlike the conventional sharp endocervical curette, the Soft-ECC is intended to gently frictionally abrade and collect abundant trans-epithelial tissue samples into the patent pending KYLON fabric. The tip device containing the sample can be placed in the fixative vial and transported to the lab. In the lab, the tissue can be easily and efficiently removed from the curette fabric for processing that is identical to the conventional endocervical curettage tissue sample.
SoftBiopsy
The FDA Compliant disposable SoftBiopsy can be used to biopsy the exocervix and lower genital tract during colposcopy or when a suspicious lesion is detected. Unlike the “sharp edge” biopsy design of gynecological biopsy devices, the SoftBiopsy design is intended to gently frictionally abrade and collect abundant trans-epithelial tissue samples into the patent pending KYLON fabric. The tip device containing the sample can be placed in the fixative vial and transported to the lab. In the lab, the tissue can be easily and efficiently removed from the curette fabric for processing that is identical to the conventional lower genital tract biopsy or curettage tissue sample.
