Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the detailed description is only intended to teach one skilled in the art how to practice the invention, and is not intended to exhaust all possible ways of practicing the invention, nor is it intended to limit the scope of the invention.

In one embodiment of the intestinal dual lumen ostomy bridge device provided by the present disclosure, as shown in fig. 1, the intestinal dual lumen ostomy bridge device comprises a stent bridge, a balloon 30, a trachea 40 and an inflation and deflation fitting 50.

The stent bridge includes a bridge body 10 and a connection body 20, the bridge body 10 being formed in an arch shape, and the connection body 20 being bent at both ends of the bridge body 10 with respect to the bridge body 10. The "inboard" side of the bridge 10 is defined below as the side of the arch that bulges out, and the "outboard" side of the bridge 10 is the side opposite the inboard side.

As shown in fig. 3, each of the two connection bodies 20 at both ends of the bridge body 10 has a through hole 21, and an axis of the through hole 21 is parallel to a plane in which an axis of the bridge body 10 is located, or an axis of the through hole 21 is located on the same plane as the axis of the bridge body 10. More specifically, the axis of the through-going hole 21 may also extend in the height direction of the bridge 10.

During surgery, the intestinal tract is pulled out of the abdominal cavity through the stoma, the bridge 10 spans the stoma, and the intestinal tract pulled out of the stoma is supported by the bridge 10 on the outside of the bridge 10. The connecting body 20 is brought into contact with the skin tissue (skin or subcutaneous tissue) around the stoma, and the surgeon may thread the thread through the through-hole 21 and the skin tissue to thereby connect the stent bridge to the skin tissue.

Thus, the stent bridge is firmly fixed and not easy to slip, the intestinal canal and the stoma which are pulled out from the stoma are supported by the stent bridge, and the bridge body 10 is fixed on the skin or the subcutaneous tissue through the connecting body 20, so that the intestinal canal is fixed relative to the stoma, the stoma can not be sunk or narrowed, and the content of the intestinal canal can be smoothly discharged.

Of course, the axis of the through-going hole 21 may also be inclined with respect to the height direction of the bridge 10.

As shown in fig. 2, the bridge 10 may be cylindrical, i.e. the cross-section of the bridge 10 is circular. The diameter of the cross-section may be 0.3cm to 0.8cm, more preferably may be 0.5 cm.

It should be understood that the cross-section of the "cylinder" may include a strict circle, and may also include a substantially circle, such as an ellipse, an oval, etc., as long as the cross-section has a rounded profile.

Since the bridge body 10 is located inside the abdominal cavity during the operation, the bridge body 10 with a smooth outer contour, such as the cylindrical bridge body 10, has no corners and will not damage the tissues in the abdominal cavity.

The bridge 10 may be formed in a rounded shape so that the bridge 10 fits well with the tissue at the stoma and provides a smooth contact surface for the intestinal canal.

The span of the bridge 10 may be 2cm to 3cm, and more preferably, the span B of the bridge 10 may be 3 cm. The height H of the bridge 10 may be 1.5cm to 2.5cm, and more preferably, the height H of the bridge 10 may be 2 cm.

The bridge 10 of this size is capable of receiving and supporting the bowel of most patients.

The connecting body 20 may be integrally formed with the pontic 10, so that a coupling process between the connecting body 20 and the pontic 10 may be omitted, thereby avoiding the use of coupling materials and reducing the risk of infection.

The connecting body 20 may extend along the bridge body 10 in a direction of a line connecting both ends of the bridge body 10, so that the overall shape of the stent bridge is identical to the anatomical structure of the stoma, and the stent bridge can be conveniently constructed at the stoma.

The connector 20 can be secured to the dermal tissue in two connection modes: first, it is attached to the skin surface outside the abdominal cavity; second, it is inserted under the skin and connected to the subcutaneous tissue.

For the first attachment, as shown in FIG. 1, it is defined that the "inner" side of the connector 20 is the side facing the skin and the "outer" side of the connector 20 is the side opposite the "inner" side.

As shown in FIG. 3, the inner side of the connector 20 may have a flat connecting surface for engaging the surface of the skin on the outside of the abdominal cavity. Thus, when the first connection method is adopted, the connection body 20 can be well attached to the skin surface.

The connection body 20 has a base end portion 22 connected to the bridge 10 and a tip end portion 23 distant from the bridge 10, and the connection body 20 gradually decreases in size, i.e., thickness, in the height direction of the bridge 10 in a process of extending from the base end portion 22 to the tip end portion 23, i.e., the connection body 20 is formed in a substantially wedge shape.

During the operation, need connect the excrement and urine collection bag in the department of making a mouthful to make the excrement and urine outflow in the patient intestines, the thickness of connector 20 attenuate gradually can avoid connector 20 to exceed skin too much, makes the excrement and urine collection bag connect better like this, and then avoids excrement and urine to reveal and make a mouthful infection on every side.

The connecting body 20 is smoothly transited in the course of extending from the bridge body 10. Thus, the connector 20 is not angular during extension and does not substantially damage and cause infection to the skin tissue when the second mode of connection is employed.

The balloon 30 may be attached to the bridge 10 at an outer side of the bridge 10, with one end of the gas tube 40 connected to the balloon 30 and the other end of the gas tube 40 connected to an inflation and deflation fitting 50, the inflation and deflation fitting 50 being used for connecting an inflation component, such as a syringe. The inflation member is inflatable so that the gas enters the airbag 30 through the inflation/deflation joint 50 and the gas tube 40 in this order, and the airbag 30 is inflated. The gas in the airbag 30 can be discharged through the gas pipe 40 and the inflation/deflation joint 50 in sequence, and the airbag 30 collapses.

The balloon 30 may be attached to the bridge 10 by means common in the art and should not cause damage to the body tissue.

As shown in FIG. 4, the inflation and deflation fitting 50 may comprise a valve core 51 and an air bag 52. The air bag 52 includes a bag body having a through hole communicating with the other end of the air tube 40 and an air bag opening in which the valve core 51 is mounted. The inflation member may be connected to the valve core 51, and when the airbag 30 is inflated, the valve core 51 is automatically opened by gas, and the valve core 51 supplies gas to pass through the bag 52 from the outside to the inside of the bag 52 in one direction. When the air bag 30 is deflated, the core of the valve core 51 is depressed, and the gas flows out through the valve core 51.

Since the balloon 30 is in contact with the intestinal tube, the intestinal tube bulges more to the outside of the abdominal cavity when the balloon 30 is inflated; when the balloon 30 collapses, the bowel tube is more recessed into the interior of the abdominal cavity.

It can be seen that the level of the irregularity of the intestinal tract at the stoma can be flexibly adjusted by adjusting the amount of gas in the balloon 30. Moreover, the intestinal tube is in contact with the balloon 30, and the balloon 30 can flexibly contact the intestinal tube by changing the shape, thereby preventing edema of the intestinal tube and protecting the normal physiological function of the intestinal tube.

The bag 52 communicates with the balloon 30, and the gas pressure in the balloon 30 can be sensed by holding the bag 52, so that the doctor can easily judge whether or not the balloon 30 needs to be inflated or deflated.

The stent bridge of the intestinal double-lumen stoma bridge device provided by the present disclosure may be made of medical plastics, the trachea 40 may be made of silica gel material, and the air sac 30 may be made of medical elastic rubber.

The bracket bridge of the intestinal double-cavity stoma bridge device provided by the disclosure conforms to the anatomical structure around the stoma, does not cause obvious abnormality of the anatomical structure, is convenient to operate, simplifies the operation process, saves hands, protects the intestinal canal from being damaged as much as possible, and reduces the occurrence of operation complications.

It should be understood that the above embodiments are exemplary only, and are not intended to limit the present invention. Various modifications and alterations of the above-described embodiments may be made by those skilled in the art in light of the teachings of the present invention without departing from the scope thereof.
