Abstract

The utility model discloses a cardia and anastomotic stoma shaping bracket, which belongs to the medical appliance. The shaping bracket is a bracket in shape of round pipe, and fine steel wire springs are wound inside the surrounding walls of the shaping bracket; a one-way valve is arranged downwards inside the pipe; valve sheets are respectively arranged on both ends of a bracket body, and a funnel-shaped upper opening and a conical lower opening are formed by bonding and retracting the connection points on the side edges of the valve sheets; a pull rope is arranged on the outer part of the bracket body for taking out or hanging the bracket. The shaping bracket designed in this way, can be stably placed in the cardia, without proneness of sliding or shifting; the one-way valve can prevent the contents in a stomach from flowing back; the bracket can be applied to the narrow cardia, a cardia cancer, the achalasia of the cardia, and a narrow anastomotic stoma.

Description

Cardia and anastomotic stoma matrix support

This utility model relates to a kind of cardia, anastomotic stoma shaped bracket, belongs to medical supplies.

Preventricular stenosis, achalasia of the cardia and upper digestive tract anastomotic stenosis after surgery often must be implemented cardioplasty clinically, or the anastomotic stoma plasty, increase misery to patient.And in clinical treatment work, still there are not corresponding utensils such as cardia and anastomotic stoma shaped bracket.

It is esophageal carcinoma expandable stent that the U.S. once produced a kind of Esophageal Stent of placing through scope, the stake body of this silicone rubber tube is longer, to keep the patient with esophageal carcinoma feed unobstructed, because support body is long, infundibulate lower port diameter suitable for reading and coniform is a bit larger tham pipe diameter, and easily gliding comes off, and also is difficult for taking out, and anti-stream is serious, is unsuitable for the shaping of cardia or anastomotic stoma and uses.

The purpose of this utility model is exactly to be convenient to dispensing, to take out through scope in order to provide a kind of, and can strut by the nationality upper and lower opening, surely places the shaped bracket of cardia or anastomotic stoma, therefore, and this utility model prior art of having any different.

This utility model is by following conceptual design.

In perisporium, be respectively the limb that turns up around the tubulose support body two ends of finer wire spring in advance, and after limb both sides graininess junction point is bonding, form funnel-form end opening suitable for reading and coniform; Pipe shape support body stretches out duck by inwall below in pipe and chews shape one-way membrane lobe; The outer silica gel drag wire two ends of stake body are fixed in respectively on the wall inner spring of funnel and corresponding position, both sides, support body joint portion, make it to be snare.

During use, the wire guide that utilizes the Savary dilator is in gastroscope movable detecting hole is delivered to gastral cavity, and dilator reaches orificium cardiacum expansion about 1.6cm, gastroscope shank overcoat upper bracket pusher and support, the cardia place after under the gastroscope direct-view this support being sent into expansion.This support conus portion junction point fusing, owing to lose the gathering of junction point, limb self elasticity makes it to turn up, and is stuck in the cardia position with microwave probe; Drag wire is passed from the nostril, adjust suitable length, be enclosed within on patient's ear.This support has been finished cardioplasty after keeping somewhere the cardia 1-3 of place month.Reuse microwave probe fusing infundibulum junction point splits infundibulum and is the limb valgoid, and drag wire is drawn from the oral cavity, slightly firmly lifts, this support can be pulled out outside the oral cavity, and unlikely meeting accident.

She Ji cardia, anastomotic stoma shaped bracket are easy to dispensing, are easy to take out like this, place and stablize, and avoid the displacement that comes off of gliding, the part expansion of loosening can prevent that cicatrix from tearing, make patient exempt the misery of cardia surgery plasty,, can prevent that also gastric from holding anti-stream owing to be provided with downward one-way membrane lobe.

Below in conjunction with drawings and Examples it is described this utility model.

Fig. 1 draws sketch map in for this utility model limb.

Fig. 2 is this utility model limb sketch map that turns up.

Fig. 3 is this utility model vertical profile front view.

The piped stake body of circle 1. in the perisporium in advance 2. around the finer wire spring, to keep the intensity and the toughness of tubulose stake body, unlikely distortion, the top is to turn up the limb that struts 3., 4-5 leaf limb relies on limb dual-side graininess junction point, and 4. bonding to become funnel-form with gathering suitable for reading, the 4-5 leaf limb that the stake body bottom also struts for turning up is 5. 4. bonding through the graininess junction point, and drawing in becomes coniform end opening.1. pipe shape stake body stretches out duck by inwall below in pipe and chews shape one-way membrane lobe 6., holds anti-stream to avoid gastric.The 1. outer silica gel drag wire of stake body 7. two ends is fixed in the wall of funnel and corresponding position, both sides, support body joint portion wire spring respectively and 2. goes up, and makes it to be snare, is beneficial to and takes out support, tractive or hitch use, and avoid tearing stake body.

By cardia, the anastomotic stoma shaped bracket total length 5-6cm that such scheme adopts medical poisonless moulded silicone rubber pipe to make, the long 2.4cm of stake body, external diameter 1.6-1.8cm, internal diameter 1.2cm, silica gel drag wire total length 60-80cm.Through clinic trial, obtain satisfied forming effect.

Claims

1, a kind of cardia, anastomotic stoma shaped bracket are suitable for reading by funnel-form, and the tubular bracket body of coniform end opening and mid portion constitutes, and in advance around the finer wire spring, it is characterized in that in the support body perisporium:

A. these stake body two ends are respectively and turn up limb and form funnel-form end opening suitable for reading and coniform after the bonding gathering of limb both sides graininess junction point;

B. pipe shape stake body is chewed shape one-way membrane lobe by stretching out duck below inwall is in pipe;

C. the outer drag wire two ends of stake body are fixed in respectively on the wall inner spring of funnel and corresponding position, both sides, support body joint portion, make it to be snare.

2, shaped bracket according to claim 1 is characterized in that this support funnel-form limb suitable for reading and coniform end opening is the 4-5 leaf.
