Title:
INTESTINAL TUBE WELDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/139084
Kind Code:
A1
Abstract:
An intestinal tube welding device, comprising: two welding heads (10), each welding head comprising a main body (11) and a ring electrode (12) disposed at an end of the main body; the ring electrode is electrically connected to a high-frequency power source used for providing a high frequency voltage; the main body comprises a pair of clamping pieces (111-112) that are movably connected; the ring electrode is composed of a pair of semi-ring sub-electrodes (121-122), and the pair of semi-ring sub-electrodes are respectively disposed at ends of the pair of clamping pieces. The welding device has a simple structure and, when used for welding an intestinal tube, can improve the hemostasis effect, prevent intestinal stenosis, and prevent secondary injury to a patient caused by an intestinal side wall incision, thereby reducing the pain of the patient and speeding up recovery by the patient.
