Multifunctional scalpel for digestive ERCP

Abstract

The invention discloses a multifunctional scalpel for digestive ERCP, and belongs to the field of electric scalpels for endoscopic surgeries. The multifunctional scalpel for the digestive ERCP comprises a scalpel body, an insulating tube and an electrode body, wherein the scalpel body comprises a fixed operation part fixedly connected with the insulating tube, a first movable operation part and asecond movable operation part; the fixed operation part is sleeved with the first movable operation part and the second movable operation part; the first movable operation part and the second movableoperation part slide in the length direction of the fixed operation part; and the second movable operation part is located between the first movable operation part and the insulating tube. A needle head electric scalpel and a conventional incision knife in the prior art are combined, so that the needle knife incision and conventional incision functions can be achieved at the same time; the forwardincision and reverse incision functions are achieved in the conventional incision direction; needle knife incision and conventional incision can be freely switched without replacing the whole electric scalpel; and the reverse incision can be realized during the conventional incision, so that the duodenal papilla incision of a patient after a gastrointestinal operation can be facilitated, the operation speed is greatly increased, the operation time is greatly shortened, and the pain duration of the patient due to the operation is shortened.

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.

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
