Description
Technical Field
The utility model relates to the technical field of medical equipment, especially relate to a type drainage tube is prevented flowing backward in ultrasonic endoscope intervention treatment.
Background
In recent years, with the rapid advance of digestive endoscopy equipment and related instruments, the unprecedented development of minimally invasive surgeries under various endoscopes, particularly the deep fusion of ultrasonic technology and endoscope technology, is more open to an unprecedented new field, realizes a plurality of treatments which can be realized only through surgical operations and interventional operations before, these fields are often of a type that is less preferred by surgical and interventional procedures, such as endoscopic ultrasound-guided puncture and drainage of pseudocysts in the pancreas, endoscopic ultrasound-guided puncture and drainage of bile ducts/pancreatic ducts, the minimally invasive surgery punctures pathological changes under the guidance of an ultrasonic endoscope and is arranged in a corresponding drainage tube to achieve the drainage purpose, thereby eliminating the pathological changes or relieving obstruction, although the application of new technologies has brought great hopes to such patients and actually solved many patients' illnesses. However, with the deep development of new technology and new operation, the defects of the existing drainage tube are slowly revealed, such as the problems of backflow and blockage of gastric juice of a plastic drainage tube and a metal drainage support, which causes the problems of reduced drainage effect, delayed lesion healing, incapability of normal feeding of patients for a long time, and the like.
A drainage tube used for the drainage of digestive tract puncture under the existing common ultrasonic endoscope is a double-pigtail plastic drainage tube, after the puncture is successful, one end of the drainage tube is arranged in a pathological change, and the other end of the drainage tube is arranged in a gastric cavity.
The other drainage tube is a metal tubular or double mushroom head drainage tube used for the gastrointestinal puncture drainage under the ultrasonic endoscope, after the puncture is successful, one end of the drainage tube is arranged in the pathological change, and the other end of the drainage tube is arranged in the gastric cavity, the drainage tube is characterized in that the inner diameter is thicker and about 10mm, the drainage effect is obviously better than that of the former drainage tube, the defects that the drainage tube is opened in the stomach and the opening is large, gastric juice and food are easy to flow back into the pathological change and are not beneficial to the healing of the pathological change, and the external drainage tube is required to be added after the drainage tube is pulled out in the later period to promote the further. And the drainage tube is not made of special metal, so that the price is high, about 2 ten thousand on average, and the economic burden of a patient is obviously increased.

Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural view of the anti-backflow drainage tube for the interventional therapy of ultrasonic endoscopy of the present invention;
wherein: 1-head, 2-connecting part, 3-tail, 4-taper pipe, 5-side hole, 6-opening and 7-hole with side flap.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The utility model aims at providing a type of flowing backward type drainage tube is prevented in supersound scope intervention treatment to solve the problem that prior art exists, make the unobstructed validity of drainage tube increase, reduce the incidence of stomach content adverse current problem and the relevant infection of adverse current.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1: the embodiment provides a type drainage tube is prevented flowing backward in ultrasonic endoscope intervention treatment, including integrated into one piece's head 1, connecting portion 2 and afterbody 3 in proper order, head 1, connecting portion 2 and afterbody 3 all communicate each other, all are provided with a plurality of side opening 5 on the lateral wall of head 1 and afterbody 3, and head 1 is opening 6 annular, can effectively prevent to shift and flow backwards. The head 1, the connecting part 2 and the tail 3 are all made of TPE materials, and plasticity and resilience are good.
Specifically, the inner diameters of the pipelines of the head part 1, the connecting part 2 and the tail part 3 are all 2.5mm, and the outer diameters thereof are all 2.8 mm. The tail end of the head part 1 is connected with a section of taper pipe 4, so that the narrow part can be conveniently passed through, the small end of the taper pipe 4 is the tail end, and the diameter of the opening 6 is 2 mm. The diameter of the side holes 5 of the head 1 is 4mm, and the distance is 10 mm.
The side hole 5 of the tail part 3 is provided with a side valve hole 7, the diameter is 5mm, the distance is 20mm, the side valve is the same with the pipe inlet direction, and the backflow can be effectively prevented. The tail end of the tail part 3 is hemispherical, so that the damage to intestinal mucosa can be reduced, and the diameter of an opening 6 arranged at the top end of the hemisphere is 1mm, so that a guide wire is arranged in a penetrating way.
The connecting part 2 is provided with a plurality of specifications with different lengths of 20-40cm, the corresponding length can be selected according to requirements, and the anti-backflow drainage tube for the ultrasonic endoscope interventional therapy is suitable for the situation of draining a puncture channel or a natural cavity channel in cases such as pancreatic pseudocyst drainage, EUS-PD, EUS-BD and gallbladder.
When the tail part 3 is arranged at the descending part of the duodenum, the stomach content cannot directly enter the lesion area, the food rarely remains in the duodenum due to the peristalsis of the duodenum and is accelerated to be emptied, and a small amount of countercurrent part hardly reaches the lesion area in the emptying process; the backflow of intestinal contents can be reduced to the greatest extent by the side flap hole 7 on the tail portion 3, the blockage of the drainage tube is prevented, the unobstructed period of the drainage tube is prolonged, and the economic burden of a patient can be greatly reduced.
