Description
Technical Field
The invention belongs to the technical field of medical appliances, and particularly relates to an auxiliary hemostatic device for liver, gall and pancreas surgery.
Background
When bleeding, the blood is treated in a certain way, and the blood is stopped from flowing outwards quickly, which is called hemostasis. The hemostatic effect varies from person to person. Fast and slow, platelet-related.
Normally, bleeding caused by damage to small blood vessels stops itself within minutes, a phenomenon known as physiological hemostasis. Physiological hemostasis is one of the important protective mechanisms of the body, as a result of the interaction of multiple factors and mechanisms. The hemostatic process mainly comprises three processes of vasoconstriction, platelet thrombosis and blood coagulation.
When stopping bleeding, the blood platelets are quickened to aggregate to the edge of the wound and intertwine, so that the blood is quickened to coagulate, and fibrin is produced at the wound. The drugs for activating blood and removing stasis are properly matched. The blood goes up and down along with qi, and sometimes the drugs for regulating qi-flowing are properly matched. Can be used for treating various hemorrhagic diseases. It is indicated for various bleeding syndromes such as hematemesis, epistaxis, hemoptysis, hematochezia, hematuria and metrorrhagia. According to the different causes of bleeding, the specific application of the hemostatic method also includes three therapeutic methods of clearing heat and stopping bleeding, tonifying qi and stopping bleeding, and removing blood stasis and stopping bleeding. Heat-clearing and bleeding stopping are indicated for bleeding caused by bleeding due to blood heat or heat injury to blood collaterals. Qi tonifying and bleeding stopping are indicated for bleeding due to qi deficiency or yang deficiency failing to control the flow of qi and blood. The prescription is usually composed of astragalus root, kitchen soil, baked ginger, aconite root, mugwort leaf and other medicines, and represents the prescription such as Guipi decoction, loess decoction and the like. It is indicated for bleeding caused by obstruction of collaterals by blood, internal resistance of blood circulation and blood failing to circulate channel. Commonly used formulas are composed of peach kernel, red peony root, notoginseng, etc., which are indicated for ectopic pregnancy. The following 4 points should be noted when the method is used clinically specifically: (1) the symptoms and signs of the illness should be grasped. (2) Excessive bleeding, qi failing to nourish the qi and consolidate the blood, and sudden bleeding is caused. (3) Bleeding is easy to cause stasis.
The method for stopping bleeding mainly comprises compression hemostasis, ligation hemostasis, electrocoagulation hemostasis, topical medicine or biological hemostasis, tourniquet hemostasis, etc.; at present, the electrocoagulation hemostasis is widely applied to hepatobiliary pancreatic surgery; but the electrocoagulation hemostasis device in the prior art is low in intelligent degree, cannot be adjusted in multiple angles and various aspects, is time-consuming and labor-consuming to operate, and greatly increases the working strength of medical staff. And because some surgical procedures are lengthy, it is not possible to relieve the physician of the working pressure.
Aiming at the problems, the auxiliary hemostatic device for the hepatobiliary pancreatic surgery can reduce the labor intensity of medical staff and assist in hemostasis during the operation.
