Hegar Dilators
Hegar dilators are dilators used to treat vaginismus and induce cervical dilation, and for inflatable penile implant procedures, though for penile implants it has been shown that outcomes are better ''without'' dilation. Description Hegar dilators were developed and introduced by Alfred Hegar in 1879 originally for use in the field of gynecology. Typically, dilators are a set of metal rods of increasing diameters, from a few millimeters up to 26 millimeters. The rods are round, slightly curved, and have a conal tip. Some sets have conal tips at both ends, while others have one end flattened for easy handling. Hegar dilators are typically marked with a Hegar number that is equivalent to its size in millimeters (e.g., a Hegar size 8 is 8 mm thick). Commercially available Hegar dilators are commonly sold in sets of 8, 10, or 14 individual rods. Each set includes a range of sizes, popularly from 3 mm to 17 mm for single-ended dilators or 3 mm / 4 mm to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dilator
Dilator or dilatator is a medical term with a number of uses, including: *A surgical instrument or medical implement used to induce dilation, that is, to expand an opening or passage such as the cervix (see cervical dilator), urethra, esophagus, or vaginal introitus. *A pharmacological treatment used to induce dilation, such as cervical dilation, vasodilation, or pupillary dilation. For example, a bronchodilator. *A muscle which causes dilation of a part, for example, the iris dilator muscle or the dilator naris muscle. See also *Stent In medicine, a stent is a tube usually constructed of a metallic alloy or a polymer. It is inserted into the Lumen (anatomy), lumen (hollow space) of an anatomic vessel or duct to keep the passageway open. Stenting refers to the placement of ... * Vaginal dilator {{medical-equipment-stub Medical equipment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaginismus
Vaginismus is a condition in which involuntary muscle spasm interferes with vaginal intercourse or other penetration of the vagina. This often results in pain with attempts at sex. Often it begins when vaginal intercourse is first attempted. Vaginismus may be considered an older term for pelvic floor dysfunction. The formal diagnostic criteria specifically require interference during vaginal intercourse and a desire for intercourse, but the term ''vaginismus'' is sometimes used more broadly to refer to any muscle spasm occurring during the insertion of objects into the vagina, sexually motivated or otherwise, including speculums and tampons. The underlying cause is generally a fear that penetration will hurt. Risk factors include a history of sexual assault, endometriosis, vaginitis, or a prior episiotomy. Diagnosis is based on the symptoms and examination. It requires there to be no anatomical or physical problems (e.g., pelvic floor dysfunction, vulvodynia, vestibu ...

Cervix
The cervix (: cervices) or cervix uteri is a dynamic fibromuscular sexual organ of the female reproductive system that connects the vagina with the uterine cavity. The human female cervix has been documented anatomically since at least the time of Hippocrates, over 2,000 years ago. The cervix is approximately 4 cm long with a diameter of approximately 3 cm and tends to be described as a cylindrical shape, although the front and back walls of the cervix are contiguous. The size of the cervix changes throughout a woman's life cycle. For example, women in the fertile years of their reproductive cycle tend to have larger cervixes than postmenopausal women; likewise, women who have produced offspring have a larger cervix than those who have not. In relation to the vagina, the part of the cervix that opens to the uterus is called the ''internal os'' and the opening of the cervix in the vagina is called the ''external os''. Between them is a conduit commonly called the cervic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penile Implant
A penile implant is an Implant (Medicine), implanted device intended for the treatment of erectile dysfunction, Peyronie's disease, ischemic priapism, deformity and any traumatic injury of the penis, and for phalloplasty or metoidioplasty, including in gender-affirming surgery. Men also opt for penile implants for aesthetic purposes. Men's satisfaction and sexual function is influenced by discomfort over genital size, which leads some to seek surgical and non-surgical solutions for penis alteration. Although there are many distinct types of implants, most fall into one of two categories: malleable and inflatable transplants. History The first modern prosthetic reconstruction of a penis is attributed to NA Borgus, a German physician who performed the first surgical attempts in 1936 on soldiers with traumatic Penectomy, amputations of the penis. He used Costal cartilage, rib cartilages as prosthetic material and reconstructed the genitals for both Urination, micturition and Sexua ...

Alfred Hegar
Ernst Ludwig Alfred Hegar, ''aka'' Alfred Hegar, was a German gynecologist famous for developing new medical tools and techniques. He was born on 6 January 1830 in Darmstadt, Germany and died on 5 August 1914. He was buried in Breisgau. Hegar was the son of Johann August Hegar (1794–1882), a country Doctor. He studied medicine in Giessen, Heidelberg, Berlin and Vienna, and after graduation went into the army and worked as military physician. He later went into private practice as an obstetrician in the city of Darmstadt. Alfred Hegar was chosen to be the successor of Otto Spiegelberg as professor for gynecology and obstetrics at the University of Freiburg in 1864 and was the first head of the Universitäts-Frauenklinik of the University Medical Center Freiburg when it opened in 1868. Hegar also founded the journal "Beiträge zur Geburthilfe und Gynäkologie" in 1898. He was a pioneer of antiseptics and antiseptic procedures. Hegar retired in 1904. Among the many techniques and ...

Gynecology
Gynaecology or gynecology (see American and British English spelling differences) is the area of medicine concerned with conditions affecting the Female reproductive system, female reproductive system. It is often paired with the field of obstetrics, which focuses on pregnancy and childbirth, thereby forming the combined area of obstetrics and gynaecology (OB-GYN). Gynaecology encompasses both Primary care, primary and Preventive healthcare, preventative care of issues related to female reproduction and sexual health, such as the uterus, vagina, fallopian tubes, ovaries, and breasts; subspecialties include family planning; minimally invasive surgery; pediatric and adolescent gynecology; and pelvic medicine and reconstructive surgery. While gynaecology has traditionally centered on Cisgender, cisgender women, it increasingly encompasses anyone with female organs, including transgender, intersex, and Non-binary gender, nonbinary individuals; however, many non-cis women face acce ...

Hymen
The hymen is a thin piece of mucosal tissue that surrounds or partially covers the vaginal opening. A small percentage of females are born with hymens that are imperforate and completely obstruct the vaginal canal. It forms part of the vulva and is similar in structure to the vagina. The word is from the Greek ''ὑμήν'' meaning a thin skin or membrane. In children, a common appearance of the hymen is crescent-shaped, although many shapes are possible. Each shape in the natural range has a Latinate name. During puberty, estrogen causes the hymen to change in appearance and become very elastic. Normal variations of the post-pubertal hymen range from thin and stretchy to thick and somewhat rigid. Very rarely, it may be completely absent. The hymen can rip or tear during first penetrative intercourse, which usually results in pain and, sometimes, mild temporary bleeding or spotting. Minor injuries to the hymen may heal on their own, and not require surgical intervention. His ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cervical Dilation
Cervical dilation (or cervical dilatation) is the opening of the cervix, the entrance to the uterus, during childbirth, miscarriage, induced abortion, or gynecological surgery. Cervical dilation may occur naturally, or may be induced surgically or medically. In childbirth In the later stages of pregnancy, the cervix may already have opened up to 1–3 cm (or more in rarer circumstances), but during labor, repeated uterine contractions lead to further widening of the cervix to about 6 centimeters. From that point, pressure from the presenting part (head in vertex births or bottom in breech births), along with uterine contractions, will dilate the cervix to 10 centimeters, which is "complete." Cervical dilation is accompanied by effacement, the thinning of the cervix. General guidelines for cervical dilation: * Latent phase: 0–3 centimeters * Active labor: 4–7 centimeters * Transition: 8–10 centimeters * Complete: 10 centimeters. Delivery of the infant takes place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uterus
The uterus (from Latin ''uterus'', : uteri or uteruses) or womb () is the hollow organ, organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic development, embryonic and prenatal development, fetal development of one or more Fertilized egg, fertilized eggs until birth. The uterus is a hormone-responsive sex organ that contains uterine gland, glands in its endometrium, lining that secrete uterine milk for embryonic nourishment. (The term ''uterus'' is also applied to analogous structures in some non-mammalian animals.) In humans, the lower end of the uterus is a narrow part known as the Uterine isthmus, isthmus that connects to the cervix, the anterior gateway leading to the vagina. The upper end, the body of the uterus, is connected to the fallopian tubes at the uterine horns; the rounded part, the fundus, is above the openings to the fallopian tubes. The connection of the uterine cavity with a fallopian tube is called the utero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
