Digestive endoscopy ercp surgery multifunctional scalpel

Abstract

The invention discloses a multifunctional scalpel for digestive endoscopic ERCP surgery, which belongs to the field of electric knife for endoscopic surgery. The multifunctional scalpel for digestive endoscopic ERCP surgery includes a knife body, an insulating tube and an electrode body; The fixed operating part, the first movable operating part and the second movable operating part which are sleeved outside the fixed operating part and slide along its length direction, the second movable operating part is located between the first movable operating part and the insulating tube, and the present The combination of needle-shaped head electric knife and conventional incision knife in the technology makes it have the functions of needle knife incision and conventional incision at the same time. The direction of conventional incision has the function of forward incision and reverse incision. Open and conventional incision can be switched at will without replacing the entire electrotome. During conventional incision, the incision can be reversed, which is beneficial to duodenal papillatomy for patients diverted after gastrointestinal surgery, which greatly improves the operation speed and greatly reduces The operation time is shortened, and the patient's pain time caused by the operation is reduced.

Description

technical field [0001] The invention relates to the field of endoscopic surgery electric knife, more specifically, relates to a multifunctional scalpel for digestive endoscopic ERCP surgery. Background technique [0002] With the continuous development of the medical and health industry, the degree of informationization of hospitals is gradually improving, and the medical system is gradually improving. Various digital applications based on hospital information systems are also becoming more and more extensive. [0003] At present, the most commonly used in the gastrointestinal endoscopy department is the conventional incision electrosurgical knife. During the operation, through the doctor's operation, the electrode at the surgical end in the patient's body is exposed in an arc shape, so that the electrode is energized, and the exposed arc is used to energize the electrode. In addition, sometimes it is necessary to use a needle-shaped electric knife to open the duodenal papil...

Problems solved by technology

[0003] At present, the most commonly used in the gastrointestinal endoscopy department is the conventional incision electrosurgical knife. During the operation, through the doctor's operation, the electrode at the surgical end in the patient's body is exposed in an arc shape, so that the electrode is energized, and the exposed arc is used to energize the electrode. In addition, sometimes it is necessary to use a needle-shaped electric knife to open the duodenal papilla. The former is line resection, and the latter is point resection. When using it, high-frequency and high-voltage are passed through the electrodes inside the electric knife. However, the two kinds of electrosurgical units usually exist independently. When the needle-shaped electrosurgical unit breaks the nipple, it needs to be replaced when the conventional incision electrosurgical unit is used for resection, which is cumbersome and greatly improves the manufacturing cost
