Cusco's self-retaining bivalved speculum is a surgical instrument used for vaginal and cervical examination. It has a jaw that opens up like a duck bill.
The instrument was named after French surgeon Édouard-Gabriel Cusco (1819–1894). [1]
It comes in three models: side screw, centre screw, and special narrow virgin size. [2] Cusco's speculum is usually 80 millimeters (3.1 in) long and 22 millimeters (0.87 in) 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. [3] 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. Because it covers most of the vaginal wall, small lesions on the vaginal wall may be masked by the blades of the device. [4]
In mammals, the vagina is the elastic, muscular part of the female genital tract. In humans, it extends from the vulva to the cervix. The outer vaginal opening is normally partly covered by a membrane called the hymen. At the deep end, the cervix bulges into the vagina. The vagina allows for sexual intercourse and birth. It also channels menstrual flow (menses), which occurs in humans and closely related primates as part of the monthly menstrual cycle.
A micrometer, sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw widely used for accurate measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are usually, but not always, in the form of calipers. The spindle is a very accurately machined screw and the object to be measured is placed between the spindle and the anvil. The spindle is moved by turning the ratchet knob or thimble until the object to be measured is lightly touched by both the spindle and the anvil.
Gynaecology or gynecology is the medical practice dealing with the health of the female reproductive system. Outside medicine, the term means "the science of women". Its counterpart is andrology, which deals with medical issues specific to the male reproductive system.
Prostate massage is the massage or stimulation of the male prostate gland for medical purposes or sexual stimulation.
A scalpel, or lancet, or bistoury, is a small and extremely sharp bladed instrument used for surgery, anatomical dissection, podiatry and various arts and crafts. Scalpels may be single-use disposable or re-usable. Re-usable scalpels can have permanently attached blades that can be sharpened or, more commonly, removable single-use blades. Disposable scalpels usually have a plastic handle with an extensible blade and are used once, then the entire instrument is discarded. Scalpel blades are usually individually packed in sterile pouches but are also offered non-sterile. Double-edged scalpels are referred to as "lancets".
A speculum, 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.
A pessary is a prosthetic device inserted into the vagina for structural and pharmaceutical purposes. It is most commonly used to treat stress urinary incontinence to stop urinary leakage, and pelvic organ prolapse to maintain the location of organs in the pelvic region. It can also be used to administer medications locally in the vagina or as a method of contraception. Pessaries come in different shapes and sizes, so it is important that individuals be fitted for them by health care professionals to avoid any complications.However, there are a few instances and circumstances that allow individuals to purchase pessaries from a store without a prescription or without seeking help from a health care professional. Some side effects may occur if pessaries are not sized properly or regularly maintained, but with the appropriate care, pessaries are generally safe and well tolerated.
Vaginoplasty is any surgical procedure that results in the construction or reconstruction of the vagina. It is a type of genitoplasty. Pelvic organ prolapse is often treated with one or more surgeries to repair the vagina. Sometimes a vaginoplasty is needed following the treatment or removal of malignant growths or abscesses in order to restore a normal vaginal structure and function. Surgery to the vagina is done to correct congenital defects to the vagina, urethra and rectum. It will correct protrusion of the urinary bladder into the vagina (cystocele) and protrusion of the rectum (rectocele) into the vagina. Often, a vaginoplasty is performed to repair the vagina and its attached structures due to trauma or injury.
Medical gloves are disposable gloves used during medical examinations and procedures to help prevent cross-contamination between caregivers and patients. Medical gloves are made of different polymers including latex, nitrile rubber, polyvinyl chloride and neoprene; they come unpowdered, or powdered with corn starch to lubricate the gloves, making them easier to put on the hands.
Vaginal photoplethysmography is a technique using light to measure the amount of blood in the walls of the vagina. The device that is used is called a vaginal photometer.
Vaginal atresia is a condition in which the vagina is abnormally closed or absent. The main causes can either be complete vaginal hypoplasia, or a vaginal obstruction, often caused by an imperforate hymen or, less commonly, a transverse vaginal septum. It results in uterovaginal outflow tract obstruction. This condition does not usually occur by itself within an individual, but coupled with other developmental disorders within the female. The disorders that are usually coupled with a female who has vaginal atresia are Rokitansky-Mayer- Küster-Hauser syndrome, Bardet-Biedl syndrome, or Fraser syndrome. One out of every 5,000 women have this abnormality.
Vaginal hypoplasia is the underdevelopment or incomplete development of the vagina. It is a birth defect or congenital abnormality of the female genitourinary system.
A pelvic examination is the physical examination of the external and internal female pelvic organs. It is frequently used in gynecology for the evaluation of symptoms affecting the female reproductive and urinary tract, such as pain, bleeding, discharge, urinary incontinence, or trauma. It can also be used assess a patient's anatomy in preparation for procedures. The exam can be done awake in the clinic and emergency department, or under anesthesia in the operating room. The most commonly performed components of the exam are 1) the external exam, to evaluate the external genitalia 2) the internal exam with palpation to examine the uterus, ovaries, and fallopian tubes, and 3) the internal exam using the speculum to visualize the vaginal walls and cervix. During the pelvic exam, sample of cells and fluids may be collected to screen for sexually transmitted infections or cancer.
The endometrial biopsy is a medical procedure that involves taking a tissue sample of the lining of the uterus. The tissue subsequently undergoes a histologic evaluation which aids the physician in forming a diagnosis.
The following is a list of instruments that are used in modern obstetrics and gynecology.
Surgical mesh is a loosely woven sheet which is used as either a permanent or temporary support for organs and other tissues during surgery. Surgical mesh is created from both inorganic and biological materials and is used in a variety of surgeries. Though hernia repair surgery is the most common application, it can also be used for reconstructive work, such as in pelvic organ prolapse.
A well woman examination is an exam offered to women to review elements of their reproductive health. The exam includes a breast examination, a pelvic examination and a pap smear but may also include other procedures. Hospitals employ strict policies relating to the provision of consent by the patient, the availability of chaperones at the examination, and the absence of other parties.
Pediatric gynaecology or pediatric gynecology is the medical practice dealing with the health of the vagina, vulva, uterus, and ovaries of infants, children, and adolescents. Its counterpart is pediatric andrology, which deals with medical issues specific to the penis and testes.
Sims' vaginal speculum is a double-bladed surgical instrument used for examining the vagina and cervix. It was developed by J. Marion Sims out of pewter spoon, but nowadays it is manufactured out of stainless steel or plastic. The plastic speculum is disposable, but the stainless steel one is not. Therefore, the stainless steel speculum should be sterilized before each use. Sims' speculum is inserted into the vagina to retract posterior vaginal wall. It gives more exposure of the vaginal walls than Cusco's Speculum and therefore is preferred for gynaecological surgeries. it is possible to slide the instrument around the vaginal wall to enable better visualization. The groove in the middle of Sims' speculum allows free flow of secretions and blood to the outside, thereby keeping the area dry. Sims' speculum is available in various sizes, and the size appropriate to the vaginal dimensions of the woman is chosen for use. The disadvantage of Sims' speculum is that it is not self-retracting. The examiner might want to use an anterior wall retractor in addition to Sims' speculum for better visualization of the cervix.
Vaginal cysts are uncommon benign cysts that develop in the vaginal wall. The type of epithelial tissue lining a cyst is used to classify these growths. They can be congenital. They can present in childhood and adulthood. The most common type is the squamous inclusion cyst. It develops within vaginal tissue present at the site of an episiotomy or other vaginal surgical sites. In most instances they do not cause symptoms and present with few or no complications. A vaginal cyst can develop on the surface of the vaginal epithelium or in deeper layers. Often, they are found by the women herself and as an incidental finding during a routine pelvic examination. Vaginal cysts can mimic other structures that protrude from the vagina such as a rectocele and cystocele. Some cysts can be distinguished visually but most will need a biopsy to determine the type. Vaginal cysts can vary in size and can grow as large as 7 cm. Other cysts can be present on the vaginal wall though mostly these can be differentiated. Vaginal cysts can often be palpated (felt) by a clinician. Vaginal cysts are one type of vaginal mass, others include cancers and tumors. The prevalence of vaginal cysts is uncertain since many go unreported but it is estimated that 1 out of 200 women have a vaginal cyst. Vaginal cysts may initially be discovered during pregnancy and childbirth. These are then treated to provide an unobstructed delivery of the infant. Growths that originate from the urethra and other tissue can present as cysts of the vagina.
