Smoke-removing and eschar adhesion-preventing electrocoagulation rod for laparoscope

Abstract

The present invention discloses a smoke-removing and eschar adhesion-preventing electrocoagulation rod for laparoscope. The smoke-removing and eschar adhesion-preventing electrocoagulation rod for thelaparoscope comprises an outer sleeve pipe formed by a hollow insulating tubular body, a conductive rod and a control valve; an outer sleeve pipe mouth is arranged in front of the outer sleeve pipe,a front end of the conductive rod is provided with a metal electrocoagulation head, the conductive rod is axially arranged and fixed at a center of an inner cavity of the outer sleeve pipe, the outersleeve pipe is also axially provided with a water inlet passage and a smoke exhaust passage, and both ends are respectively provided with a water inlet and a smoke exhaust mouth, a water outlet, a smoke inlet and a control valve. Through the above arrangement, the smoke-removing and eschar adhesion-preventing electrocoagulation rod has functions of electrocoagulation, water flushing and smoking removing at the same time. When the electrocoagulation produces eschar, the smoke-removing and eschar adhesion-preventing electrocoagulation rod can prevent adhesion of the eschar with an electrocoagulation head by the water flushing, and avoids secondary bleeding caused by pulling. At the same time, the smoke-removing and eschar adhesion-preventing electrocoagulation rod can also suck smoke produced by the electrocoagulation, keeps clear and visible surgical field, and thus improves a hemostatic effect and surgery safety.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electrocoagulation rod for smoke removal and anti-eschar adhesion laparoscopy. Background technique [0002] In the field of liver surgery, laparoscopic partial hepatectomy has been widely used clinically. Because the liver parenchyma contains a large number of blood vessels and has an extremely rich blood supply, wound bleeding when the liver is severed is the most common intraoperative complication of this operation. disease. Electrocoagulation rod is a common clinical medical device accessory, especially suitable for hemostasis on bleeding wounds during minimally invasive laparoscopic surgery. Therefore, for the wound bleeding of liver, kidney, uterus and other solid organs with rich blood supply, the use of intraoperative electric coagulation rod plays a key role in hemostasis. However, the existing electrocoagulation rods often encounter the following two proble...

Problems solved by technology

However, the existing electrocoagulation rods often encounter the following two problems when hemostasis: When electrocoagulating wounds, a large amount of eschar is often produced, and the eschar and the electrocoagulation metal head are easy to adhere, resulting in secondary bleeding of the wound surface that has been hemostasis due to the pulling of the metal head away from the wound surface, resulting in time-consuming and time-consuming hemostasis during the operation. It is strenuous, and in severe cases, it is even impossible to completely stop the bleeding; A large amount of smoke is often produced during electrocoagulation, which makes the surgical field blurred and seriously interferes with the operation process of the surgery. The existing laparoscopic electrocoagulation rods either do not have the function of removing smoke, or although they are equipped with suction functions, the air intake holes often It is easy to be blocked, and the smoke removal effect is difficult to meet the needs of surgery
