Surgery you know

Early surgery is limited to simple manual methods to cut, cut, and sew on the body surface, such as abscess drainage, tumor resection, and traumatic suture. Therefore, surgery is an operation that destroys the integrity of the tissue (incision) or restores the tissue whose integrity has been damaged (suturing). With the development of surgery, the field of surgery continues to expand and can be performed on any part of the human body. The applied instruments are also constantly updated. For example, scalpels include electric knife, microwave knife, ultrasonic knife and laser knife. In the treatment of pre-excitation syndrome, high-function electronic computer positioning can be used. Some surgical operations do not necessarily require cutting to destroy tissues, such as removing stones or foreign bodies in the biliary tract, urinary tract, or gastrointestinal tract through various endoscopes; dilating coronary arteries with balloons through puncture catheters, or occluding them with lasers Vascular recanalization etc. Therefore, surgery also has a broader meaning. However, the vast majority of operations are still manual operations by physicians.
