Disposable Vaginal Speculum is a medical tool for probing body perforations, with a form dependent on the perforation for which it's designed. In old textbooks, the speculum may also be appertained to as a diopter or dioptra. (1) Like an endoscope, a speculum allows a view inside the body; endoscopes, still, tend to have optics while a speculum is intended for direct vision.

Specula have been made of glass or essence. They were formerly (when?) made of pristine sword and castrated after use. Still, in the 21st century, numerous — especially those used in exigency departments and croaker's services — are now made of plastic, and are disposable, single- use particulars. Those used in surgical suites are still generally made of pristine sword.

Specula come in a variety of shapes grounded on their purpose, and a variety of sizes; (9) in any case the cylinder or blade (s) of the instrument allow the driver a direct vision of the area of interest and the possibility to introduce instruments for farther interventions similar as a vivisection.
The best- known speculum is the bivalved vaginal speculum; the two blades are depended and are" unrestricted"when the speculum is fitted to grease its entry and" opened"in its final position where they can be arrested by a screw medium, so that the driver is freed from keeping the blades piecemeal.
A spherical-structured speculum, introduced in 2001, the dilating vaginal speculum ( also known as the Veda- compass (10)) constructed by Clemens van der Weegen, (11) inflates the vagina with filtered air. (12) ( see illustration) The device has two main functions a) to take a normal Pap smear with a cervical encounter or a cytology encounter; and b) as an internal colposcope so that the driver can pivot the Veda- compass to view any part of the vagina barrel and cervix eased by an internal light source that can illuminate the vaginal wall and cervix withmulti-coloured light pollutants, which can descrypre-cancerous cells with the aid of acetic acid result and iodine result. It also has a installation to attach a digital camera for viewing and recording. (13)

A technical form of vaginal speculum is the weighted speculum, which consists of a broad partial tube which is fraudulent at about a 90 degree angle, with the channel of the tube on the external side of the angle. One end of the tube has a roughly globular essence weight girding the channel of the speculum. A weighted speculum is placed in the vagina during vaginal surgery with the case in the lithotomy position. The weight holds the speculum in place and frees the surgeon's hands for other tasks. A vaginal speculum is also used in fertility treatments, particularly artificial copulation, and allows the vaginal depression to be opened and observed thereby easing the deposit of semen into the vagina.
