Gynecological instruments (SIM`S VAGINAL SPERCULUM)

 SIM`S VAGINAL SPERCULUM:

   INDICATIONS:

1. Expose the anterior vaginal wall especially in cases of vesico- vaginal fistula, both for diagnosis (prolapse ) and for operative repair (episotomy).
2. It can also be of value to insert a vaginal pack.

      ADVANTAGES:

1. Gives an excellent view of the anterior vaginal wall.

      2. The grooved blade directs the blood or urine outside when used in the lithotomic position, and provides a space for operative work

      DISADVANTAGES:

1. Assistance is required especially when used to expose the cervix or during surgical procedures, as it is not self-retaining.

       2. In the presence of a large cystocele, exposure of the cervix is often difficult
