Multifunctional high-frequency electrosurgical pencil

Abstract

The invention provides a multifunctional high-frequency electrosurgical pencil. The multifunctional high-frequency electrosurgical pencil is characterized in that a head end and a tail end are arranged at two ends of a shell; a conductive slide is arranged in the shell, one end of the conductive slide is connected with the head end, and an electrode through hole is formed in the head end and in the position where the head end is connected with the conductive slide; an electrode is arranged in the conductive slide, and a knife head and a conductive limit portion are arranged at two ends of the electrode; one end of the electrode with the knife head extends out of the electrode through hole, and the conductive limit portion is conductively contacted with the conductive slide; the electrode and the knife head are sleeved with an insulating cleaning blade, one end of the knife head extends out of the cleaning blade, and a limit section is arranged on the electrode; LED lamps and blow holes are arranged in the head end, and the blow holes are connected with an air inlet connector via an air duct. The cleaning blade is used for cleaning the knife head; the LED lamps are used for lighting the surgical field; the electrode is telescopic and is suitable for different situations, and frequent exchanging of the knife head is not needed; the air blowing function is arranged, and air blowing can be performed during surgical operation to remove smoke, bleeding, drainage and the like of the surgical field.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multifunctional high-frequency electric knife pen. Background technique [0002] Surgical knife is a necessary instrument in surgery, which can be used for tissue electric cutting and electrocoagulation to stop bleeding. In the process of using electric knife to cut and electrocoagulate hemostasis, there will inevitably be active tissue bleeding, smoke and knife head being stained by cauterized tissue, which will affect the operation and the operative field will be unclear. The doctor needs to stop the bleeding and clean up before continuing the operation. . During the operation, due to the fast bleeding speed, the blood quickly covers the bleeding point, and the doctor cannot precisely electrocoagulate the hemostasis. It is necessary to use a suction device or auxiliary materials to remove the bleeding first, and then stop the bleeding after exposing the bleeding poin...
