Abstract
The invention relates to a bellow type anti-falling esophageal stent. According to the structure of the esophageal stent, the two ends of the anti-falling esophageal stent are respectively with a horn mouth, the middle of the anti-falling esophageal stent is provided with an anti-falling corrugated protrusive ring, and the anti-falling esophageal stent is formed by weaving stainless steel wires or a titanium alloy in a net tube shape. The esophageal stent is placed on the canceration portion of the esophagus through a general placing instrument, under the elastic action of the esophageal stent, the canceration portion of the esophagus is opened slowly so that the esophagus can be unblocked, while being opened by the esophageal stent, a cancerous lump must adapt to the shape of the esophageal stent and therefore wraps the esophageal stent according to the appearance of the esophageal stent, under the damping action of the anti-falling corrugated protrusive ring, the wrapped esophageal stent can be completely prevented from falling off due to physiological peristalsis of the esophagus, the trouble of repeated installation through operations due to repeated falling of the esophageal stent is saved, and pains and risks brought to a patient due to the repeated operations are greatly reduced.
Description
Technical field
The present invention relates to technical field of medical instruments, specifically a kind of bellows-type slip-off preventing Esophageal Stent.
Background technology
If there is canceration in human body esophagus, esophagus can be stopped up, cause patient can not swallow food and hungry and dead, in order to extend patient's life, prior art is to be placed in esophagus diseased region esophagus is strutted recalling netted straight tube Esophageal Stent that alloy makes, expand the intracavity diameter at pathological changes esophagus position, with instant food, pass through, the operation of laying of this Esophageal Stent is implemented under gastroscope helps, but the problem existing is, after Ultimum Ti Esophageal Stent is laid, the esophageal canceration position that finds that there is a lot of patients is blocked again, cause and swallow food difficulty, through x-ray fluoroscopy, discovery is because of esophageal peristalsis and swallow coarse granule food Ultimum Ti Esophageal Stent is pushed away in stomach, the solution of prior art is that the Esophageal Stent that uses special-purpose shearing apparatus under the help of gastroscope, Ultimum Ti to be made is sheared broken bit by bit, by biopsy forceps, take out one by one again, and then lay the Esophageal Stent of a new Ultimum Ti, perform the operation very complicated, patient is very painful, operation increases doctor's labor intensity for a long time, also increased patient's medical expense, the solution also not had at present.
Summary of the invention
Technical assignment of the present invention is to solve the deficiencies in the prior art, and a kind of bellows-type slip-off preventing Esophageal Stent is provided.
Technical scheme of the present invention realizes in the following manner, and the two ends of slip-off preventing Esophageal Stent are provided with horn mouth, and the centre of slip-off preventing Esophageal Stent is provided with slip-off preventing ripple bulge loop.
Described slip-off preventing Esophageal Stent is to be woven into net tubular by stainless steel silk or titanium alloy.
thisinvention
'sa kind of bellows-type slip-off preventing Esophageal Stent
there is following outstanding beneficial effect:
This Esophageal Stent has simple in structure, with low cost, has good anti-drop function, and slip-off preventing principle is as follows:
Esophageal Stent is laid apparatus by being put into esophageal canceration position by general, under the elastic reaction of Esophageal Stent, esophageal canceration position is slowly strutted, make esophagus unimpeded, when Esophageal Stent struts cancerous protuberance piece, cancerous protuberance piece must adapt to the shape of Esophageal Stent, thereby cancerous protuberance piece wraps up the profile according to Esophageal Stent to Esophageal Stent, parcel is later under the damping action of slip-off preventing ripple bulge loop, can avoid Esophageal Stent to come off under esophagus peristalsis completely, avoided repeatedly coming off and repeatedly implemented the trouble that operation is installed, misery and risk that greatly having alleviated performs the operation repeatedly brings to patient.
This Esophageal Stent can be used common stainless steel silk to make, replace the Ultimum Ti that tradition is expensive, before operation, need not carry out freezing memory to Esophageal Stent, using the tradition mode of laying to lay puts in place, not only facilitating operation, operating time are short, patient's misery is little, and doctor's labor intensity is low, can also greatly alleviate patient's medical expense.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of bellows-type slip-off preventing Esophageal Stent.
Labelling in accompanying drawing represents respectively: slip-off preventing Esophageal Stent 1, slip-off preventing bulge loop 2, horn mouth.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A kind of slip-off preventing Esophageal Stent of the present invention, its structure is that the two ends of slip-off preventing Esophageal Stent 1 are provided with horn mouth 3, the centre of slip-off preventing Esophageal Stent 1 is provided with slip-off preventing ripple bulge loop 2.
Described slip-off preventing Esophageal Stent 1 is to be woven into net tubular by stainless steel silk or titanium alloy.
Embodiment
It is as follows that slip-off preventing Esophageal Stent is laid operating procedure:
Under the supervision of X-ray machine, slip-off preventing Esophageal Stent is enclosed within on general slip-off preventing Esophageal Stent placing device, after stretched distortion, send into esophageal canceration position, after putting in place, slip-off preventing Esophageal Stent takes out laying bracket, the Esophageal Stent shape of recovering before stretcher strain that slowly expands struts the esophagus of obstruction, patient's liquid food of can swallowing.
Except the disclosed technical characterictic of description of invention, be the known technology of those skilled in the art.
Claims (2)
1. a bellows-type slip-off preventing Esophageal Stent, comprises slip-off preventing Esophageal Stent, it is characterized in that, the two ends of slip-off preventing Esophageal Stent are provided with horn mouth, and the centre of slip-off preventing Esophageal Stent is provided with slip-off preventing ripple bulge loop.
