Argon Plasma ESU Clinical Application

Argon Plasma ESU Clinical Application

(1) Surgery

A. Application of General Surgery and Hepatobiliary Surgery: The argon plasam is particularly suitable for surgeries involving substantial organs and large areas of bleeding. The argon ion beam scans back and forth on the wound, and the argon airflow can blow away blood, making the surgical field of view clearer. Thus achieving a hemostatic effect.

B. Liver transplantation: The argon Plasam ESU is particularly suitable for recipient patients undergoing liver transplantation, who often suffer from portal hypertension with many collateral circulation in the separation area, especially in the anhepatic phase. For severe bleeding of the liver bed, the argon knife is a reliable hemostatic device.

C. Application of thoracic surgery: During routine lung resection, sometimes the lung segment is removed or the plane of the lung segment is torn during surgery without passing through the interlobular fissure resection surface. The use of an argon knife can effectively stop bleeding and seal air leakage. For solid tumors, especially those located under the pleura, when biopsy is needed for diagnosis, the diseased tissue can be completely removed, and then effective hemostasis can be performed using an argon knife or a combination of traditional electric knives. In summary, the advantages of using argon knife in thoracic surgery are to preserve lung function as much as possible and reduce intraoperative bleeding and transfusion.

D. At present, cardiac surgery, especially coronary artery bypass grafting, has significantly increased the complexity of the surgery, often requiring extensive dissection, which inevitably leads to infiltration of blood. In this case, bleeding can be completely controlled using an argon knife. The use of an argon knife on the surface of the heart, like traditional bipolar electrocoagulation, can cause ventricular fibrillation. Therefore, when treating myocardial surface exudation, an argon knife should be used to stop bleeding before the heart resumes beating.

E. Orthopedic application: In the surgery of pathological fractures of the femur, during the exposure process of the vascular tumor, an argon knife is used to form a layer of scab on the soft tissue and bone surface of the cut vascular tumor, which has a very good hemostatic effect. In fact, the argon knife has a good hemostatic effect on the extremely rich soft and bone tissues of blood vessels, indicating the bright future of this equipment in orthopedic surgery.

F. Application to tumors: In the past, non massive resection surgery can be performed to reduce cancer cells in areas where ovarian cancer cannot be removed. The surgery for incubating nest cancer includes transabdominal total hysterectomy with bilateral ovariectomy, omentectomy, and primary tumor block resection. During the surgery, it can be used to stop bleeding and destroy tumor tissue outside the resection line. For metastatic tumors in the pelvic cavity, such as the anterior and posterior walls of the rectum and uterus, after sharp resection of the tumor from the (bone volume) artery and vein, an argon knife (40W power) is used to stop bleeding and destroy the small residual tumor tissue. Whether using an argon knife, intraperitoneal chemotherapy, or full abdominal radiotherapy, as long as the visible tumor tissue can be completely destroyed, patients can have several years of tumor free survival. The application of argon knife in the surgery of primary and secondary reduction of tumor tissue in ovarian cancer.

(2) Internal Medicine Department

A. Digestive tract diseases: including Barrett's esophagus, Zenke diverticulum, advanced esophageal cancer, malignant stenosis, restenosis of the upper and lower ends of the mesh and stent after esophageal stent placement;

B. Gastrointestinal bleeding, gastric vascular disease, colitis with bleeding, gastric and colon cancer bleeding;

C. Gastric tract polyps, especially suitable for flat and wide base polyps with a diameter less than or equal to 1.5cm;

D. Early gastrointestinal tumors;

E. Other indications: including Dieulafoy ulcer, verrucous gastritis, etc

(3) Scope of application: Argon knife is mainly used in general surgery, hepatobiliary surgery, thoracic surgery, obstetrics and gynecology, etc
