Description

Catheter for protecting stoma intestinal canal in operation

Technical Field

The invention relates to the field of medical instruments, in particular to a catheter for protecting an ostomy intestinal canal in operation.

Background

Parastomal hernia is one of the common complications after enterostomy. Most PSH patients are asymptomatic and can receive conservative treatment. However, 11-70% of patients will eventually require at least one surgery due to an emergency situation of increased symptoms, difficulty in ostomy care (leakage, discomfort) or the occurrence of obstruction, incarceration, etc. In a patient with parastomal hernia, because the fascia is defective at the side of the stomal, the intestinal canal is convoluted and adhered after entering the hernia sac, so that the risk of damaging the intestinal canal exists in the process of separating the adhesion of the intestinal canal in the hernia sac in the parastomal hernia repair operation. Also, the ostomy and embedded intestine are convoluted with each other, and the differentiation during the operation is difficult, which causes difficulties and challenges to the operation

At present, in order to avoid injuring the intestinal canal by mistake in the operation, some measures are also taken by a clinician, the most common is foley's urinary catheter, and the specific use method is as follows: after the towel is disinfected and laid, the aseptic catheter is inserted into an intestinal canal through a stoma, and then 15-20ml of normal saline is injected into the saccule through the syringe interface. In the operation, the stoma intestinal canal can be judged by observing the intestinal canal uplift and the method that the instrument touches the intestinal canal. However, this method has a great disadvantage: (1) the water injected by Foley's urinary catheter balloon cannot exceed 30ml, otherwise the balloon is ruptured because the internal pressure is too large, and the bulge of the intestinal canal at the balloon is difficult to observe; (2) the maximum model of the Foley's ureter is 24Fr, the corresponding diameter is 8mm, the touch sense of the endoscopic instrument is much worse than that of the endoscopic instrument which is directly touched by hands, and the ureter in the intestinal canal is difficult to sense by the instrument; (3) foley's urinary catheter is difficult to fix, is influenced by intestinal peristalsis during operation, and can slowly slip off, so that a catheter for protecting an ostomy intestinal tube during operation is provided.
