Identification

An obstetric-gynecologic specialized manual instrument is one of a group of devices used during obstetric-gynecologic procedures to perform manipulative diagnostic and surgical functions (e.g., dilating, grasping, measuring, and scraping), where structural integrity is the chief criterion of device performance. This type of device consists of the following:(1) An amniotome is an instrument used to rupture the fetal membranes. (2) A circumcision clamp is an instrument used to compress the foreskin of the penis during circumcision of a male infant. (3) An umbilical clamp is an instrument used to compress the umbilical cord. (4) A uterine curette is an instrument used to scrape and remove material from the uterus. (5) A fixed-size cervical dilator is any of a series of bougies of various sizes used to dilate the cervical os by stretching the cervix. (6) A uterine elevator is an instrument inserted into the uterus used to lift and manipulate the uterus. (7) A gynecological surgical forceps is an instrument with two blades and handles used to pull, grasp, or compress during gynecological examination. (8) A cervical cone knife is a cutting instrument used to excise and remove tissue from the cervix. (9) A gynecological cerclage needle is a looplike instrument used to suture the cervix. (10) A hook-type contraceptive intrauterine device (IUD) remover is an instrument used to remove an IUD from the uterus. (11) A gynecological fibroid screw is an instrument used to hold onto a fibroid. (12) A uterine sound is an instrument used to determine the depth of the uterus by inserting it into the uterine cavity. (13) A cytological cervical spatula is a blunt instrument used to scrape and remove cytological material from the surface of the cervix or vagina. (14) A gynecological biopsy forceps is an instrument with two blades and handles used for gynecological biopsy procedures. (15) A uterine tenaculum is a hooklike instrument used to seize and hold the cervix or fundus. (16) An internal pelvimeter is an instrument used within the vagina to measure the diameter and capacity of the pelvis. (17) A nonmetal vaginal speculum is a nonmetal instrument used to expose the interior of the vagina. (18) A fiberoptic nonmetal vaginal speculum is a nonmetal instrument, with fiberoptic light, used to expose and illuminate the interior of the vagina.

Special Controls

## Dimensional Analysis

Measurements were taken of both the smallest and the largest Konig Bell Circumcision Clamps to ensure that the devices meet the specifications on the engineering drawings. A total of thirteen samples of both the smallest and largest bell sizes were used. All thirteen samples of both sized clamps met the acceptance criteria for dimensions.

## Grip Testing

Comparison grip testing was performed on the predicate, Fine Surgical Circumcision Clamp and the Konig Bell Circumcision Clamp. To simulate use with actual foreskin, a latex substrate was loaded into the circumcision clamps and pulled vertically above and below the clamp with approximately 10N of force. The latex substrate was then inspected for slippage from the clamp and any signs of cuts, tears, or visible damage. Both the predicate and the subject devices met the acceptance criteria for grip strength.

## Corrosion Testing

Corrosion testing using the boil test per ASTM F1089-18 was performed on thirteen samples of the Konig Bell Circumcision Clamp. The instruments were thoroughly cleaned using an ultrasonic cleaner and then boiled in a glass container with distilled water for 30 minutes. After 30 minutes the circumcision clamps were removed and allowed to air dry for 2 hours. After drying, the instruments were inspected for any rust formation. All thirteen samples successfully met the acceptance criteria and did not show any signs of corrosion.
