Abstract
The utility model discloses an expandable esophageal stent. The expandable esophageal stent comprises a cylindrical-tube-shaped stent body, an expandable air bag and a suspension tube, wherein the outer cylindrical surface of the stent body is covered by the expandable air bag, and the suspension tube is connected with one end of the stent body and communicated with the expandable air bag. The expandable esophageal stent can well fit the esophagus of the human body in shape, is free of an expansion part or a spine part stimulating the esophagus and has excellent tolerance; the suspension tube penetrates out of the nasal cavity of a patient and is fixed outside the human body through adhesive tape and the like, so that the problem that the esophageal stent shifts or falls off due to the physiologic peristalsis of the esophagus is solved; after being implanted in the esophagus for a spell, if the stent body deforms due to growth of the peripheral tissues, the expandable air bag can be inflated through the suspension tube to expand the peripheral tissues of the stent body, and the stent body can automatically recover in the original shape, so that the problem that stent body is squeezed and deforms due to growth of the peripheral tissues of the stent body is solved, and the esophageal stent is long in service life and good in treatment effect.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of Esophageal Stent.
Background technology
Esophagostenosis or esophago-tracheal fistula are the even serious diseases of life of serious threat patients ' life quality, be implanted into Esophageal Stent at esophageal lumen, it is treatment esophagostenosis or esophago-tracheal fistula is more convenient, safe, effective, a kind of method of Wicresoft, apply clinically at present more, but also there is distinct disadvantage in this Therapeutic Method, as:
1, existing Esophageal Stent is easily because there is displacement and the problem that comes off in the reasons such as esophagus physiological wriggling.At present, in order to solve the displacement of Esophageal Stent and the problem that comes off, conventionally the one or both ends of Esophageal Stent are made to the expansion position of special shape, as " horn-like ", " goblet shape " or " bulb shape " etc., or arrange and stretch out cradle wall and thrust the metal agnail of esophageal tissue in the one or both ends of Esophageal Stent, to strengthen the stability of Esophageal Stent implantation position; But the expansion position of Esophageal Stent and agnail make patient produce the malaise symptoms such as foreign body sensation after can causing again support to implant, and agnail causes the risk of esophageal wall and surrounding tissue damage in addition.
2, implanting after Esophageal Stent a period of time, due to the growth of Esophageal Stent surrounding tissue, and Esophageal Stent has certain elasticity, and the problem of distortion also easily appears being extruded in Esophageal Stent.
Therefore need a kind ofly to eliminate Esophageal Stent displacement, come off and the novel Esophageal Stent of problem on deformation.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of expansible type Esophageal Stent, to solve the easy displacement that existing Esophageal Stent exists, the problem that comes off and be out of shape.
The expansible type Esophageal Stent of this utility model, comprise cylindrical tube stake body, cover expanded balloon and the column pipe being connected with stake body one end on stake body external cylindrical surface, described column pipe and expanded balloon are communicated with.
Further, described stake body comprises the steel-wire carcass of straight tube-like and is coated on the silicone rubber membrane outside steel-wire carcass.
Further, the two ends of described stake body are provided with the silicone rubber shirt rim of toroidal.
Further, described column pipe comprise be connected with silicone rubber membrane body and be arranged at the steel wire fibre being connected in body and with steel-wire carcass.
Further, on the outer surface of described column pipe, be provided with linear measure longimetry scale.
The beneficial effects of the utility model:
1, the expansible type Esophageal Stent of this utility model, its stake body is cylindrical tube, can well coincide with human body esophageal lumen shape, does not have the expansion section or the sharp portion that stimulate esophagus, makes it have good toleration; Implant after esophagus at stake body simultaneously, column pipe can be passed from patient's nasal cavity and be fixed on external by adhesive plaster etc., thereby can eliminate the problem that stake body causes ground Esophageal Stent displacement, comes off because of esophagus physiological wriggling etc., fixing good reliability, therapeutic effect is good.
2, the expansible type Esophageal Stent of this utility model, implanting after esophagus a period of time, in the time that stake body deforms because of its surrounding tissue growth, can inflate to expanded balloon by column pipe, Esophageal Stent tissue is around expanded, make patient's esophagus become large, allow stake body recover original shape in self elastic force effect, therefore this Esophageal Stent can be eliminated the problem that is extruded distortion because of its surrounding tissue growth, esophagus long service life, and therapeutic effect is better.
Brief description of the drawings
Fig. 1 is the structural representation of the expansible type Esophageal Stent of this utility model;
Fig. 2 is the zoomed-in view of P portion in Fig. 1;
Fig. 3 is the cross sectional representation of column pipe.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
As shown in the figure, expansible type Esophageal Stent, comprise cylindrical tube stake body 1, cover expanded balloon 2 and the column pipe 3 being connected with stake body 1 one end on stake body 1 external cylindrical surface, described column pipe 3 and expanded balloon are communicated with 2.
The present embodiment expansivity Esophageal Stent, its stake body 1 is cylindrical tube, can well coincide with human body esophageal lumen shape, and it does not exist and stimulate expansion section or the sharp portion of esophagus, makes it have good toleration; Implant after esophagus at stake body 1 simultaneously, column pipe 3 is passed from patient's nasal cavity and is fixed on by adhesive plaster etc. external, thereby can eliminate the problem that stake body 1 causes ground Esophageal Stent displacement, comes off because of esophagus physiological wriggling etc., fixing good reliability.And implanting after Esophageal Stent a period of time, in the time that stake body 1 deforms because of its surrounding tissue growth, can inflate to expanded balloon 2 by column pipe 3, Esophageal Stent tissue is around expanded, make patient's esophagus become large, allow stake body recover original shape in self elastic force effect, therefore this Esophageal Stent can be eliminated the problem that is extruded distortion because of its surrounding tissue growth, esophagus long service life, therapeutic effect is better.
As the improvement to the present embodiment, described stake body 1 comprises the steel-wire carcass 101 of straight tube-like and is coated on the silicone rubber membrane 102 outside steel-wire carcass; The intensity of steel-wire carcass 101 and resilience are good, can ensure Esophageal Stent dimensional stability in therapeutic process, and silicone rubber membrane 102 contacts comfort level with esophageal wall good, can alleviate the sense of discomfort of implanting after Esophageal Stent.
As the improvement to the present embodiment, the two ends of described stake body 1 are provided with the silicone rubber shirt rim 4 of toroidal.Can well fit with esophagus inwall in silicone rubber shirt rim 4, can further alleviate the stimulation of stake body 1 end to esophagus, and can prevent that food from flowing out from stake body 1 outer wall.
