Description

Esophageal fistula negative pressure sponge stopper

Technical field

This utility model relates to medical instruments field, particularly relates to a kind of esophageal fistula negative pressure sponge stopper.

Background technology

Esophageal fistula is the complication of esophageal carcinoma severe postoperative; make a general survey of more than 100 year operating history in the past; this serious complication of esophageal fistula is just paid close attention to by various countries medical science scholar always; though the method for coincideing and resist technology are gone through the development of decades; the incidence rate of esophageal fistula is declined to some extent, but the incidence rate of esophageal fistula is still higher.It is reported that current esophageal carcinoma esophageal fistula incidence rate is 5%-15%.Although the incidence rate of cervical fistula will be higher than Thorax esophgus fistula, mortality rate and the extent of injury of Thorax esophgus fistula are higher.Usually can fester in the esophageal fistula place of esophagus, produce pus, pus need to be sucked, and impels surrounding tissue to cover in early days, and better sooner, this just need to suck pus by drainage tube.But use traditional drainage tube can not effectively dwindle fistula mouth, can not promote surrounding tissue to cover fistula mouth, healing time is longer, and case fatality rate is higher.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of esophageal fistula negative pressure sponge stopper, has realized the efficient sucking-off of esophageal fistula place waste liquid, and has promoted esophagus surrounding tissue to cover in early days fistula mouth, does not cause further damage, and conveniently inserts drainage tube.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of esophageal fistula negative pressure sponge stopper is provided, comprise drainage tube, sleeve pipe, connection tube and spongy top, connection tube one end links with spongy top, the other end of connection tube is provided with female thread, drainage tube comprises the first noumenon and the second body, the external diameter of the first noumenon equals the external diameter of connection tube, the internal diameter of second body diameter and connection tube matches and the second body is provided with external screw thread, external screw thread and female thread match, sleeve pipe is wrapped in outside spongy top and connection tube, on spongy top, be provided with developing line.Before use, use as required the spongy top of different model, choose after spongy top, connection tube on spongy top is threaded with drainage tube, and then casing pipe sleeve is placed in outside spongy top and drainage tube, due to the effect of sleeve pipe, by the volume-diminished of spongy top, be more prone to spongy top to extend in esophagus.When use, sleeve pipe is extend in esophagus, by the guide effect of sleeve pipe, spongy top and drainage tube enter into esophagus, because sleeve pipe is wrapped in outside spongy top, can prevent that Endo-esophageal material from entering in spongy top, avoid stopping up spongy top, improve waste liquid sucking-off effect below.Inserting in the process of sleeve pipe, owing to being provided with contrast agent on spongy top, under the irradiation of X-ray, can see the position of spongy top clearly, spongy top can be extend in esophageal fistula accurately.After spongy top extend in esophageal fistula, sleeve pipe is extracted, at this moment spongy top is released, and spongy top laminating esophageal fistula place, more effectively by waste liquid sucking-off.The free end of drainage tube connects negative pressure, and waste liquid is sucked out, along with being sucked out with esophagus surrounding tissue of waste liquid covers fistula mouth, esophageal fistula place is more and more less, due to the elastic reaction of spongy top, can diminish along with diminishing of esophageal fistula place, can further not damage esophageal fistula place.

Further, described spongy top is cylindrical structure, is applicable to the esophageal fistula place of cylindrical shape.

Further, the diameter of described cylindrical structure is 2cm or 3cm, matches with the diameter at esophageal fistula place.

Further, the height of described cylindrical structure is 3cm, 5cm or 10cm, matches with the length at esophageal fistula place.

Further, described spongy top is sphere structure, matches with the shape at esophageal fistula place.

Further, the diameter of described sphere structure is 1.5cm, matches with the size of spherical esophageal fistula.

Further, the described drainage tube for esophageal fistula also comprises the first air bag, the first breather and the first air valve, the first Air sac cover is placed on the first noumenon and near the second body setting, after one end of the first breather is communicated with the first air bag, collection is loaded in the first noumenon, and the other end of the first breather passes the first noumenon and is connected with the first air valve.After sleeve pipe is extracted, open the first air valve, gas enters into the first air bag by the first breather, and the first air bag is heaved, and drainage tube is stuck in esophagus, prevents in the time of sucking-off waste liquid in mouth that saliva enters into esophageal fistula place, prevents that esophageal fistula place from being polluted once again.

Further, described sleeve pipe comprises the first body, the second body, connecting rod and slide block, the first body and the second body are hollow cylinder body structure, on the first body, centered by the center of circle, bottom surface of the first body, be provided with annular sliding tray, in the first body, be provided with the telescopic hole being communicated with sliding tray, the second body slides and is arranged in sliding tray, one end of connecting rod is connected with the second body in sliding tray, shuttle back and forth in telescopic hole in the middle part of connecting rod, the other end of connecting rod is connected with slide block, the first body is greater than the external diameter 0.5cm of drainage tube for being enclosed within drainage tube internal diameter outer and the first body, the second body is used for being enclosed within outside spongy top.Because spongy top is soft, in the time extracting sleeve pipe, sleeve pipe does not have hard material to have relative power to sleeve pipe, is difficult to sleeve pipe to extract, and is easy to take spongy top out of esophageal fistula place.For solving appeal problem, the second body is set and the first body is slidably connected, in the time that needs are extracted sleeve pipe, first first body of holding with a firm grip, does not rock the first body, pulls slide block, slide block drives the second body by connecting rod, and the second body slips in the first body.Because the first body does not rock, the second body slides with respect to the first body, easily the second body is slided in the first body, and the first body has conflict effect to spongy top, prevents that spongy top from skidding off the fistula mouth place that coincide.

Further, described sleeve pipe is hard flexible pipe, prevents from damaging esophagus, effectively drainage tube and spongy top is played to guide effect again simultaneously.

Further, drain pipe range is 1m, and the external diameter of described the first noumenon is 0.5cm, and the internal diameter of the first body is 1cm.

The beneficial effects of the utility model: 1) use drainage tube and spongy top, spongy top is close to esophageal fistula place in real time, has realized efficient the waste liquid at esophageal fistula place sucking-off, and the flexibility of spongy top, has also prevented further damage; 2) use sleeve pipe, assist drainage tube and spongy top are put into esophagus; 3) on spongy top, put contrast agent, realized accurately stretching into of spongy top; 4) adopt being threaded of connection tube and drainage tube, realized being flexibly connected of spongy top and drainage tube, realized the replaceable of spongy top.
