Non-endoscopic gastrostomy device replacement

Abstract

The invention discloses a percutaneous endoscopic gastrostomy tube replacing device without assistance of an endoscope. The device is composed of a traction tong assembly and an internal fixation sheet removal assembly, wherein the traction tong assembly comprises a sheath pipe, a pair of traction tongs, a traction tong bracket and a regulating handle; the pair of traction tongs comprises two tong heads which are hinged on the traction tong bracket; hemispherical grooves are formed in the inner surfaces of the tong heads, and the surfaces of the hemispherical grooves of the tong heads are magnetic; the internal fixation sheet removal assembly comprises a clamping ferrule and a puncture sleeve; a cavity is formed in the clamping ferrule; a connecting line is connected to the inner bottom surface of the cavity; a magnetic guide ball is connected to the head end of the connecting line; the guide ball is mutually attractive with the surfaces of the hemispherical grooves in the tong heads of the traction tong; the puncture sleeve is detachably connected to the bottom end of the clamping ferrule; a lead wire is connected to the bottom end of the clamping ferrule; and the lead wire runs through an inner hole of the sleeve. The device disclosed by the invention has the beneficial effects that without the assistance of the endoscope, the device can directly implement operations beside a bed, so that patient's burden is relieved and doctor's operating convenience is enhanced.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a PEG tube insertion auxiliary device for percutaneous endoscopic gastrostomy. Background technique [0002] Percutaneous endoscopic gastrostomy (PEG) is a type of gastrostomy that uses endoscopically mediated enteral nutrition or gastrointestinal decompression without surgery and general anesthesia. The currently widely used PEG method is the pull method. The main steps are abdominal skin preparation, intravenous prophylactic antibiotics, adequate sedation and analgesia. After pyloric obstruction, gastric wall tumors, ulcers and other lesions, air is blown into the stomach, and the anterior gastric wall is pressed against the anterior abdominal wall through the endoscope, so that the stomach is close to the abdominal wall. Another person identifies the stomach cavity, determines the puncture point, performs infiltration anesthesia on the skin and subcutaneous tissue of the corres...
