Lightning and thunder the night before surgery

Don’t worry, this won’t affect tomorrow’s surgery.

Surgery (shǒu shù) refers to the treatment that doctors use medical instruments to perform excision, suturing and other treatments on the patient's body. Use knives, scissors, needles and other instruments to operate on parts of the human body to maintain the patient's health. It is the main treatment method of surgery, commonly known as "operation". The purpose is to treat or diagnose diseases, such as removing diseased tissue, repairing damage, transplanting organs, improving the function and form of the body, etc. Early surgeries were limited to simple manual methods of cutting, cutting, and suturing on the body surface, such as abscess drainage, tumor resection, and trauma suturing. Therefore, surgery is an operation that destroys the integrity of the tissue (incision), or restores the integrity of the tissue (suture). With the development of surgery, the field of surgery continues to expand and can be performed on any part of the human body. The instruments used are also constantly updated. For example, scalpels include electric scalpels, microwave scalpels, ultrasonic scalpels, laser scalpels, etc. Surgery therefore also has a broader meaning.
