Middle digestive tract implanted tube instrument and rapid implantation method thereof

Abstract

The invention discloses a middle digestive tract implanted tube instrument. The middle digestive tract implanted tube instrument comprises a bendable elastic hollow tube with a proximal end and a distal end, and at least one fixed line fixed at a distance of 15 to 30 cm from the distal end of the hollow tube; a head end of the fixed line penetrates into the tube from the outside of the tube, threads the inner wall of the tube for a distance, then passes through the tube, threads the outer wall of the tube for a distance, then penetrates back into the tube to form a single line loop outside thetube, threads the inner wall of the tube for a distance, threads out of the tube, and ties a line knot with a tail end of the fixed line, wherein the line knot is close to the distal end of the hollow tube, the single line loop is away from the distal end of the hollow tube, and the line knot is fixed to the outer wall of the hollow tube by glue and / or a film. The middle digestive tract implantedtube instrument is ingenious in structure, easy to operate, safe and effective, can be retained for a long time, and solves the problems of nasal mucosal damage and bleeding when a nasointestinal feeding tube is implanted rapidly under a traditional endoscopy and high possibility of tube blockage caused by intracavitary coagulation after implantation.

Description

technical field

[0001] The invention relates to a pipeline device and an implantation method in the field of medical devices, in particular to a pipeline device implanted in the middle digestive tract and a rapid implantation method thereof. Background technique

[0002] The traditional nasointestinal (usually including duodenum and proximal jejunum) tube administration route is mainly used for enteral nutrient solution infusion and drug administration, and can be used for a long time, but the infusion tube cannot be fixed In the intestinal wall, it is also easy to slip into the stomach or outside the body; the operation time often exceeds 10 minutes, and the patient suffers during the period, and the operation risk increases. After some pipelines need to be implanted into the duodenum with an endoscopic clamp, the pipeline in the oral cavity needs to be diverted to the nasal cavity through a replacement device, which brings pain to the patient. Some jejunal tubes are diffi...
