Description

Foreign matter catheter device is got to alimentary canal

Technical Field

The utility model relates to the field of medical equipment, concretely relates to foreign matter pipe device is got to alimentary canal.

Background

With the rapid development of endoscope diagnosis and treatment, the endoscopic surgery is more and more active in clinic; bleeding from the mucosa of the digestive system such as intestine and stomach due to surgery or other causes can form a large amount of blood clots, affect the surgical field and can not stop bleeding effectively. The current method for dealing with blood clots in the stomach is to ensure that a patient vomits in advance, but the vomit often induces large bleeding to threaten the life of the patient. In emergency, even only the wound surface hemostasis or suture operation can be performed with the help of a surgeon depending on an open surgery; the laparotomy has large wound surface and long recovery time, and is very high in economy and time cost, because the laparotomy is percutaneous invasive treatment, the hospitalization time is increased, and medical resources are occupied to a certain extent.

At present, medical instruments such as a basket and the like are used for taking out blood clots in the market, but the blood clots are taken out under an endoscope and are not taken out under direct vision like surgery, so that the taking-out efficiency is extremely low, and the expected quick hemostasis operation effect cannot be achieved.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

referring to fig. 1 and 2, the foreign body catheter device for the digestive tract comprises an endoscope 2, a catheter 4 and a double cap 1, wherein the endoscope 2 is fixed with one end of the catheter 4 through the double cap 1, a limiting block 3 for fixing the endoscope 2 and the catheter 4 is arranged at the other end or the part of the middle part of the endoscope 2, which is attached to the catheter 4, and the limiting block 3 is provided with a limiting block buckle 301.
