Description

Technical Field

[0001] The utility model relates to the technical field of soft endoscopic surgical instrument structure design and application, in particular to a disposable flushable hemostatic forceps for an endoscope. Background Art

[0002] At present, the commonly used surgical instruments for digestive tract lesion surgery (such as endoscopic submucosal dissection (ESD)) performed via flexible endoscope are disposable mucosal cutters or high-frequency cutters, and disposable hemostatic forceps or thermal biopsy forceps. Hemostatic forceps or thermal biopsy forceps are used for intraoperative hemostasis. The exposure of the bleeding point requires flushing with the supplied water at the front end of the endoscope, and the blood can only be seen after it is flushed away. The hemostatic forceps extends from the endoscope clamp channel and needs to be aligned with the bleeding point for treatment. The existing hemostatic forceps only have the function of clamping and hemostasis. The discovery of the bleeding point depends on the auxiliary water supply at the front end of the endoscope. The flushing outlet and the hemostatic forceps outlet are not at the same point, so there is a deviation.

[0003] The existing clamp channel and auxiliary water supply flushing pipe are both independent of each other and are arranged in the endoscope body at the same time. In addition, there is inevitably a distance difference between the auxiliary water supply outlet position of the existing endoscope and the position of the clamp channel, which inevitably makes it impossible to achieve that the flushing point and the hemostatic forceps are aimed at the same point at the same time. Often, after the bleeding point is exposed after flushing, the position of the front end of the endoscope is adjusted to make the hemostatic forceps aim at the bleeding point to complete the hemostatic treatment. This is not conducive to seeing the bleeding point and treating it in the first time, which may miss the best time for hemostasis, affect the success rate and effect of hemostasis, and increase the risk of surgical treatment.

[0004] People are eager to obtain an endoscopic hemostatic forceps with better technical effects that can solve the existing technical problems. Utility Model Content
