Description
Technical Field
The invention relates to the field of surgical instruments, in particular to an extracorporeal membrane lung use scene monitoring system.
Background
Early surgery was limited to simple manual methods of cutting, incising, and suturing the body surface, such as abscess drainage, tumor excision, and trauma suturing. Surgery is a procedure that destroys the integrity of tissue (incision), or restores the integrity of the destroyed tissue (suture). With the development of surgery, the field of surgery is expanding and can be performed at any part of the human body. The applied instruments are also updated continuously, such as scalpels including electric scalpels, microwave scalpels, ultrasonic scalpels, laser scalpels and the like. Therefore, surgery also has a broader meaning.

Surgery is a procedure that destroys the integrity of tissue (incision), or restores the integrity of the destroyed tissue (suture). With the development of surgery, the field of surgery is expanding and can be performed at any part of the human body. The applied instruments are also updated continuously, such as scalpels including electric scalpels, microwave scalpels, ultrasonic scalpels, laser scalpels and the like.
