This new operation is carried out through two or three incisions only 4 ~ 5 mm long. The doctor inserted a color imaging device called "articulator" into a stainless steel probe with an incision. After seeing the joint and determining the operation to be taken on the diseased tissue, they inserted the optical fiber in the stainless steel probe into the second incision. Under the doctor's observation, the laser energy is guided to the joint through the optical fiber to cut off the injured cartilage without damaging the adjacent tissues. Because this operation uses thermal cutting, it produces instantaneous ablation and almost eliminates bleeding. Another difference from mechanical excision is that the cartilage after mechanical excision will not regenerate and the incision has burrs. Laser excision of the wound is smooth and can stimulate beneficial self-healing regeneration.
Ho: YAG laser is chosen because the laser beam with the wavelength of 2. 1 micron can be transmitted through very thin flexible optical fiber, so that doctors can reach places that were impossible to get close to before. Therefore, similar surgery is not only suitable for knee joint cavity. For example, under the control of an endoscope, laser energy can be transmitted into the bladder through an optical fiber to crush bladder stones. At present, it is also reported that endoscopic cholecystectomy can be performed, because the stones in the gallbladder can be crushed by laser through optical fiber, otherwise doctors will often have a laparotomy because the stones are too big to be pulled out from the small holes.
Some diseases often become secrets of some people because of their special reasons, which afflicts patients more than diseases with common indictable symptoms.
A patient with penile cancer had to go to Shandong Institute of Cancer Prevention to prepare for surgery because the tumor had covered the whole penis.
According to conventional treatment, patients like this should be totally removed, and the consequences can be imagined. After careful examination, Wu, director of the institute, thinks that laser treatment is effective, because the involved blood vessels and lymph are rich, and conventional surgery can not guarantee hemostasis and prevent cancer cells from spreading with lymph. Laser surgery only cuts and separates blood vessels and lymph at the same time. To the excitement of both doctors and patients, the patient recovered normal urination and sexual function two months after operation. The case was reported at the fifth academic conference of Laser Medical Branch.
"Ten people and nine hemorrhoids" is a description of many patients with hemorrhoids. In Zhejiang Xiaoshan Chengdong Laser Hospital, the operation of laser treatment of hemorrhoids can only be regarded as "pediatrics". At the invitation of Wang Chuang Lianxing, the reporter watched his operation of treating hemorrhoids for an old man with carbon dioxide laser, which ended smoothly in less than 2 minutes before and after the operation. The dean told the reporter that after the son was cured, the patient was relieved to receive laser treatment here.
Some young men and women often get into marriage difficulties because of underarm odor. A girl looks pretty, but because of her "body odor", she found some boyfriends and told them to blow out the lights. Living in the dormitory of the factory is not welcome, and no one even wants to sit at a table with her when eating in the canteen. I bought a well-publicized cosmetic, and it tasted even more strange after using it. For this reason, the girl almost lost confidence in life and is still in Chengdong Laser Hospital. After laser treatment, all the symptoms disappeared. Later, I got married and made a special trip to thank you!
At present, a considerable number of women go to the hospital for induced abortion for various reasons. However, induced abortion requires cervical dilatation in advance, which makes patients very painful. A hospital in Xi 'an uses laser to selectively irradiate relevant acupoints, which plays the role of analgesia and anesthesia, and helps abortion patients relax their cervix naturally. The whole operation is completed in a few minutes, which has no harm to human body, no side effects and no pain, and is very popular among surgeons.
Affiliated Hospital of Shandong Binzhou Medical College, from April 1988 to June19910, * * * admitted patients with imperforate hymen10/. If the traditional treatment method is adopted, X-shaped incision is needed to suture the bleeding point to stop bleeding, which is more troublesome. The hospital used carbon dioxide laser vaporization to cut and close the hymen, and the aperture was about 1 cm. It has the characteristics of convenient operation, less injury, less bleeding, no need for suture and hospitalization. No adhesion occurred after follow-up, and the success rate was 100%.
Viral dermatosis will bring a very heavy mental burden to patients. Some affect the face, and some have unbearable pain. For example, herpes zoster damages people's nervous system, herpes simplex specifically invades reproductive parts and skin mucosa, and warts can often spread to infect family members by themselves. These viral skin diseases are treated by traditional methods, which are either incurable for a long time or difficult to eradicate. The curative effect of laser treatment is very good. Because laser not only ablates and gasifies, but also interacts with organisms to produce various biological effects, which can dilate local blood vessels, improve blood circulation and enhance local immunity. More than 2000 patients with viral dermatosis were treated by laser in a domestic hospital, and the cure rate reached 100%, which confirmed the reliable curative effect of laser.
