Vaginal Dilators
A speculum (Latin for 'mirror'; : specula or speculums) is a medical tool for investigating body orifices, with a form dependent on the orifice for which it is designed. In old texts, the speculum may also be referred to as a diopter or dioptra. Like an endoscope, a speculum allows a view inside the body; endoscopes, however, tend to have optics while a speculum is intended for direct vision. History Vaginal and anal specula were used by the ancient Greeks and Romans, and speculum artifacts have been found in Pompeii. The modern vaginal speculum, developed by J. Marion Sims, consists of a hollow cylinder with a rounded end that is divided into two hinged parts, somewhat like the beak of a duck. This speculum is inserted into the vagina to dilate it for examination of the vagina and cervix. The modern vaginal speculum was developed by J. Marion Sims, a plantation doctor in Lancaster County, United States. Between 1845 and 1849, Sims performed dozens of surgeries, without anest ...

Single-use Medical Devices
Single-use medical devices include any medical equipment, instrument or apparatus having the ability to only be used once in a hospital or clinic and then disposed. The Food and Drug Administration defines this as any device entitled by its manufacturer that it is intended use is for one single patient and one procedure only. It is not reusable, therefore has a short lifespan, and is limited to one patient. There are countless types of single use medical devices, ranging from external, such as plastic gumboots, gloves and bandages merely used to assist a patient to more complex and internal devices, consisting of sharp blades, needles and tubes. Both these devices are single used, because of multiple reasons, but mainly, as it came in contact with radioactivity, blood, infection and disease or human tissue and must therefore be terminated. Each country has its own strict legislation regarding medical waste and the reprocessing of medical devices in hospitals and clinics.__TOC__ ...

Anoscopy
An anoscopy is an examination using a small, rigid, tubular instrument called an anoscope (also called an anal speculum). This is inserted a few inches into the anus in order to evaluate problems of the anal canal. Anoscopy is used to diagnose hemorrhoids, anal fissures (tears in the lining of the anus), and some cancers. Process This test is usually done in a doctor's office. The patient is required to remove their underwear, and must either lie on their side on top of an examining table, with their knees bent up towards the chest, or bend forward over the table. The anoscope is 3 to 4 inches long and the width of an average-to-large bowel movement. The doctor will coat the anoscope with a lubricant and then gently push it into the anus and rectum. The doctor may ask the patient to "bear down" or push as if they were going to have a bowel movement, and then relax. This helps the doctor insert the anoscope more easily and identify any bulges along the lining of the rectum. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Anus
In humans, the anus (from Latin ''anus'' meaning "ring", "circle") is the external opening of the rectum, located inside the intergluteal cleft and separated from the genitals by the perineum. Two sphincters control the exit of feces from the body during an act of defecation, which is the primary function of the anus. These are the internal anal sphincter and the external anal sphincter, which are circular muscles that normally maintain constriction of the orifice and which relaxes as required by normal physiological functioning. The inner sphincter is involuntary and the outer is voluntary. It is located behind the perineum which is located behind the vagina or scrotum. In part owing to its exposure to feces, a number of medical conditions may affect the anus such as hemorrhoids. The anus is the site of potential infections and other conditions, including cancer (see Anal cancer). With anal sex, the anus can play a role in sexuality. Attitudes toward anal sex vary, and it i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cusco's Speculum
In gynaecology, Cusco's self-retaining bivalved speculum is a kind of speculums, used for vaginal and cervical examinations. It has a jaw that opens up like a duck bill. The instrument was named after French surgeon Édouard-Gabriel Cusco (1819–1894). It comes in three models: side screw, centre screw, and special narrow virgin size. Cusco's speculum is usually long and broad. However, smaller and larger sizes are available. Cusco's speculum is used for introducing an intrauterine contraceptive device, taking a Pap smear, cauterization of vaginal erosion, and colposcopic examination. It is preferred in cryosurgery because it protects the anterior and posterior vaginal wall. The advantage of Cusco's speculum is that it is self-retaining. Therefore, an assistant's help is not needed to keep the speculum in place. It also acts as the vaginal wall retractor. However, it reduces the space in the vaginal cavity and therefore is not a preferred instrument for vaginal surgery. Be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lithotomy Position
The lithotomy position is a common position for surgical procedures and medical examinations involving the pelvis and lower abdomen, as well as a common position for childbirth in Western nations. The lithotomy position involves the positioning of an individual's feet above or at the same level as the hips (often in stirrups), with the perineum positioned at the edge of an examination table. References to the position have been found in some of the oldest known medical documents including versions of the Hippocratic oath (see lithotomy); the position is named after the ancient surgical procedure for removing kidney stones and bladder stones via the perineum. The position is perhaps most recognizable as the 'often used' position for childbirth: the patient is laid on the back with knees bent, positioned above the hips, and spread apart through the use of stirrups. The position is frequently used and has many obvious benefits from the doctor's perspective. Most notably the position ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgery
Surgery ''cheirourgikē'' (composed of χείρ, "hand", and ἔργον, "work"), via la, chirurgiae, meaning "hand work". is a medical specialty that uses operative manual and instrumental techniques on a person to investigate or treat a pathological condition such as a disease or injury, to help improve bodily function, appearance, or to repair unwanted ruptured areas.

Iodine
Iodine is a chemical element with the Symbol (chemistry), symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at , and boils to a violet gas at . The element was discovered by the French chemist Bernard Courtois in 1811 and was named two years later by Joseph Louis Gay-Lussac, after the Ancient Greek 'violet-coloured'. Iodine occurs in many oxidation states, including iodide (I−), iodate (), and the various periodate anions. It is the least abundant of the stable halogens, being the sixty-first most abundant element. As the heaviest essential mineral nutrient, iodine is required for the synthesis of thyroid hormones. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities. The dominant producers of iodine today are Chile and Japan.
