What Is a Nasal Speculum?
Nasal endoscope is an otolaryngology device. It is an optical device that can carry out detailed inspection of the nasal cavity. Generally referred to as a rigid tubescope, it has an angle ranging from 0 to 90 degrees. Due to the good lighting, plus itself It is relatively thin, only 2.7-4.0mm in diameter, but nasal endoscopes are sometimes referred to as tubescopes. Nasal endoscope can easily check the internal structure of the nasal cavity, nasopharynx and even the sinus through the narrow nasal cavity and the structure in the nasal passage. It is an important method to diagnose sinusitis and nasal polyps. Sinusitis and nasal polyps are delicately treated to enable surgery to reach areas not accessible with traditional surgery.
Nasal endoscope
- Nasal endoscope system with cold light source, camera and display
- Using LED light source, white LED light source, the illuminance of the light source is above 300LUX within the working range, eliminating the bulky cold light source, the color is close to daylight, making the displayed image more realistic, reducing the cost, longer life, and clearing the scene , Changed the external approach adopted by traditional rhinologists. This is especially important for rhinologists who deal with "Dongdongyanyan" all day, like seeing light in the dark.
- Large perspective. 6.2 (0 °), 5.2 (0 °), 4.4 (0 °), 6.2mm (90 °), with four different diameters and angles of the endoscope, the doctor can do a complete nasal cavity, sinus Observation of orientation.
- High resolution, no focal length limitation, and both near and far scenes are very clear.
- Nose endoscope has a magnifying effect. Moving the nasal endoscope from 3 cm to 1 cm from the observation object can enlarge the observation object
- The nasal endoscope can be connected with the camera system, so that the surgical method, the surgical cavity and other conditions are completely displayed on the monitor, which is beneficial to the surgical instructor, the operator, and the assistant to observe. Changed the rhinology surgery for many years, one person can not be seen by others, and the surgery is all based on their own "understanding" sexual disadvantages
- 1,
- 1. Hypertension and severe cardiopulmonary insufficiency.
- 2.Yes
- The brightness of this new technology is equivalent to 20 times that of the shadowless lamp. The 3 mm small hole can magnify the diseased tissue several times. During the treatment, the patient's lesions can be seen by the doctor at a glance. The clear field of vision enables the surgery to achieve a more detailed effect. It is a functional operation that removes the diseased tissue and preserves the recovery of the physiological function of the nasal cavity.
- Nasal endoscopic surgery
- If general anesthesia is used for surgery, water and fasting should be avoided for six hours after operation to prevent vomiting and asphyxia.
- If local anesthesia is used during surgery, or after six hours of general anesthesia, patients are advised to consume semi-liquid food and a semi-recumbent position.
- After removing the gauze that blocks the nasal cavity, you can eat the ordinary diet, but do not eat spicy and irritating food.
- Remove the gauze 1 ~ 2 days after operation. Before that, it is easy to feel dry mouth. Patients should drink warm water in small quantities.
- After nasal endoscopic surgery, do not spit hard, and try to avoid coughing and sneezing. The nasal stuffing cannot be removed by itself.
- To reduce headaches and bleeding, apply ice to your forehead for about six hours.
- Before and after eating for the first time after surgery, you should rinse your mouth with Dobe's solution and pay attention to your oral hygiene.
- There may be some complications after nasal endoscopic surgery. This point is described in detail in Preparation and understanding of possible complications of nasal endoscopic surgery, and patients should pay attention to it.
- Clean up the surgical cavity the next day after pulling out the sliver. At this time, if you are using nasal endoscopic surgery + traditional Chinese medicine treatment, you should also wash with traditional Chinese medicine. Thereafter, clean the surgical cavity once a day until you are discharged.
- Pay attention to follow-up visits after discharge. The initial follow-up visits last three to four weeks, and then change to two weeks based on the recovery of the surgical cavity. Generally, the follow-up visits take three months.
- Bleeding This is a more common postoperative complication. Generally speaking, patients will have bleeding and bleeding to varying degrees after surgery. Generally, patients are required to fill the nasal cavity with Vaseline gauze for 2 to 3 days.
- Orbital and intraorbital complications
- Since 1806, doctors have tried to observe the inside of the bladder with candlelight and mirrors. Edison invented the light bulb and soon applied it to the endoscope.
- The first work to be regarded as an endoscope is "Lichtleiter" (German, meaning light transmission device) made by Philip Bozzini in 1806, which is used to explore the various channels of the human body And lumen, but at the time the Medical Association of Vienna did not allow such an exploratory study; it was not until 1853 that the endoscope was really applied to the human body. With the advent of electric lamps, the light source of the endoscope has made a great leap forward, but initially the bulb was larger and placed outside the body. Shortly afterwards, the small bulb realized the ideal of in-vivo lighting.
- Jacobeus was well known for his thoracoscope in 1910 and laparoscope in 1912. By the 1930s, Heinz Kalk of Germany used laparoscopy to examine liver and gallbladder lesions. In 1937, Hope reported a laparoscopic diagnosis of ectopic pregnancy. In 1944, Raoul Palmer placed the patient in a Trendelenburg lying position with his head down and feet lowered at an angle of about 15 degrees, moving the abdominal organs to the head, and injecting gas into the abdominal cavity. More secure and reliable.
- In the 1960s, rod lenses greatly improved the image quality of endoscopes. Basil Hirschowitz invented a glass fiber with excellent light conductivity and created a flexible diagnostic endoscope. This innovation not only created the first practical medical endoscope, but also evolved all kinds of endoscopes to the era of fiberscopes (light sources and images are transmitted by optical fibers and endoscopes with flexible body).
- Endoscopes with both examination and surgical functions did not appear until the 1970s, and at that time were only used for young and healthy patients. In the 1980s, laparoscopic surgery for tubal ligation and pelvic examination has become an essential skill for gynecologists.
- The first laparoscopic cholecystectomy was completed in 1984, and the first external laparoscopic cholecystectomy was performed in 1987.
- By the 1990s, laparoscopic surgery was further extended to the appendix, spleen, colon, stomach, kidney, liver and other organs. Photocoupler (CCD) is widely used in the transmission of endoscope images. From then on, when doctors use endoscopes, they no longer have to work hard to put their eyes on the eyepieces. Instead, they can transfer the images to monitors for other medical treatments. Both personnel and patients can see what is happening inside the body.
- With the invention of surgical robotic arms, physicians can remotely perform robotic operations from a distance. The first trans-Atlantic operation was called Lindbergh's operation.
- In 2001, the first capsule camera came out. In the following years, companies successively introduced new models with improved functions. For example, a capsule camera in 2004, capsules as small as 2 cm long and 1 cm wide, capable of transmitting 30 frames and 400,000 pixels per second. Some models can even be controlled by a physician, can take tissue sections, or can deliver drugs to specific parts of the patient's body. These capsules start at $ 120 and can be powered by batteries or wirelessly.
- ENT endoscope
- ENT electronic LED endoscope adopts special capture capture software (optional), one-click capture, humanized design. And it is powerful, easy to install, does not require an external power supply, is powered by a USB interface, is convenient to carry and easy to operate, and integrates image acquisition, processing, and text editing functions. During operation, you can take photos with the button. The ENT electronic LED endoscope is equipped with professional medical electronic medical record software, which can save the patient's name, gender, age, main symptoms, diagnosis results and other clinical data and recorded images into the computer, which can be printed by editing. Examination reports are also convenient for patient follow-up and medical record statistical research, remote consultation and teaching, etc.
