Referring to fig. 1 to 3, an embodiment of the present application discloses a tamponade drainage device for maxillary cyst surgery. The stuffing drainage device can be used for maxillary cyst operation and also can be used for mandibular cyst operation. The device comprises an expansion bag 1, a catheter 2, a plurality of drainage branch pipes 3, a drainage main pipe 4 and a negative pressure drainage device 5. The inflatable balloon 1 has a balloon cavity which has a first state when not filled with a medium, as shown in fig. 1, and which is inflated to a second state after filling with a medium, as shown in fig. 2. Such as a sterile saline solution for injection, a gas, etc., as long as it can inflate the inflatable bladder 1 and is harmless to the human body.

The catheter 2 is communicated with the balloon cavity and comprises an injection channel 21, so that the medium can be injected into the balloon cavity through the injection channel 21 of the catheter 2 to expand the expansion balloon 1 into the second state, wherein the flow direction of the medium is shown by an arrow A1 in FIG. 2; alternatively, the medium (e.g., saline) in the balloon lumen is withdrawn through the infusion channel 21 of the catheter 2 to cause the balloon to contract to the first state, facilitating removal of the balloon 1 at the desired time after surgery. The shape and structure of the guide duct 2 are not limited as long as the aforementioned object can be achieved.

The plurality of branch drainage tubes 3 are used for draining the hematocele and/or the effusion in the bone cavity after the maxillary cyst operation at any time, and in some embodiments, the branch drainage tubes 3 are disposed on the wall 11 of the capsule cavity, for example, embedded in the wall 11, or, as shown in fig. 2, disposed on the surface of the wall 11. Each of the branch drainage tubes 3 includes a plurality of drainage holes 31, and each of the drainage holes 31 communicates between the inside and the outside of the branch drainage tube 3.

One end of the drainage manifold 4 is communicated with all the drainage branch pipes 3, and the other end is communicated with the negative pressure drainage device 5, so that the drainage branch pipes 3 and the drainage manifold 4 form a drainage channel 41, and the flow direction of the effusion and/or the hematocele is shown as an arrow A2 in figure 2. The drainage channel 41 and the injection channel 21 are two channels independent of each other, as shown in fig. 2.

The operation mode of the stuffing drainage device for the maxillary cyst operation is described by taking the medium as the sterile physiological saline for injection as an example as follows:

after an operation, the inflatable balloon 1 having the first state is placed in a bone cavity after a maxillary cyst operation, and then, a sterile saline solution for injection is injected into the balloon cavity of the inflatable balloon 1 through the injection passage 21 of the catheter 2, and the flow direction of the saline solution is as shown by an arrow a1 in fig. 2, and 10 ml to 20 ml is generally injected according to the size of the bone cavity of the cyst. In one embodiment, a one-way valve may be provided on the catheter 2, which is only opened in the direction of a1 in fig. 2 and closed in the direction opposite to the direction of a1, so that saline flows only in one direction into the balloon cavity and not out of the balloon cavity. The expansion balloon 1 is inflated with the injection of the physiological saline for sterile injection, and finally fills the bone cavity after the maxillary and mandibular cyst surgery, and at this time, the expansion balloon 1 is inflated to the second state. That is, the first state is a state in which the inflatable bladder 1 is not filled with a medium (e.g., physiological saline). The second state is the state in which the balloon 1 is filled with a medium, such as saline, and fills the bone cavity. As the bone cavity after the cyst of the upper and lower jaws is operated is filled by the expansion capsule 1, foreign matters outside the bone cavity can be prevented from entering the bone cavity, the bone cavity is prevented from being infected, and the healing speed of the wound area is obviously improved; secondly, the expansion capsule 1 compresses the inner wall of the bone cavity after being expanded, thereby playing the role of hemostasis. After the operation, if hematocele and/or effusion are generated in the bone cavity, the hematocele and/or the effusion are continuously drained from the drainage branch pipe 3 to the drainage main pipe 4 through the negative pressure drainage device 5 and finally flow into the negative pressure drainage device 5, so that the hematocele and/or the effusion are timely sucked, the infection can be avoided, and the healing speed of the wound area is higher. The scale arranged on the negative pressure drainage device 5 can also accurately observe the amount of hematocele and/or hydrops in the negative pressure drainage device 5 in unit time, judge the blood loss condition and the operation effect of the patient after the operation, and provide accurate basis for the curative effect evaluation after the operation.

The media inside the balloon 1 is withdrawn, for example by means of a syringe, in communication with the catheter 2, by sucking the media inside the balloon cavity of the balloon 1 out through the injection channel 21 of the catheter 2. In case a one-way valve is arranged on said catheter 2, the suction created by the syringe causes the one-way valve to open, whereby the injected medium is sucked out. Along with the medium is sucked out, the expansion capsule 1 is contracted from the second state to the first state, then the expansion capsule 1 is taken out, compared with the mode of adopting an iodoform yarn, because the volume of the expansion capsule 1 is reduced, the friction with the inner wall of the bone cavity can be reduced, particularly, when the expansion capsule 1 is made of a silica gel material, the friction force can be greatly reduced, the pain of a patient is obviously relieved, and the treatment comfort of the patient is obviously improved.

In some embodiments, referring to fig. 1 to 3, the drainage holes 31 of the branch drainage tube 3 are uniformly distributed on the outer surface of the balloon wall 11, so that after the expansion balloon 1 is expanded to the second state in the bone cavity after the cyst operation, the drainage holes 31 are uniformly distributed in the bone cavity of the cyst, thereby draining the hematocele and/or the effusion in the bone cavity to a greater extent and avoiding infection caused by the hematocele and/or the effusion in the bone cavity.

In some embodiments, the drainage apertures 31 are offset from one another, and any adjacent three of the drainage apertures are distributed at the vertices of an equilateral triangle when the bladder is inflated to the second state. So set up, can guarantee more easily the even distribution of drainage hole 31, it is low to make the degree of difficulty, drainage that also can bigger degree the hematocele and/or the hydrops of intraosseous bone are avoided hematocele and/or hydrops in the intraosseous bone cause the infection.

In one embodiment, referring to fig. 1 to 3, at least a portion of the drainage holes 31 are circular or oval in shape. That is, some of the drainage holes 31 may be circular or elliptical in shape, while other drainage holes 31 may be formed in other shapes, or all of the drainage holes 31 may be circular or elliptical in shape. So set up under the condition that the material of expansion bag 1 is silica gel, can guarantee the tension of silica gel material, avoid stress concentration to cause fill drainage device impaired. Of course, the skilled artisan will appreciate that in some embodiments, the drainage apertures 31 may be other shapes, such as triangular, etc. In short, the shape of the drainage hole is not limited as long as the effusion and/or the hematocele can be drained.

In one embodiment, referring to fig. 1-3, in the case where the drainage holes 31 are circular, the diameter of each drainage hole is 2 mm to 5 mm, such as 2 mm, 3 mm, 4 mm, or 5 mm. So set up, can be to a great extent with hematocele and/or hydrops drainage flow, moreover, can not make because the drainage hole is too big the intensity of branch drainage pipe reduces. When the diameter is larger than 5 mm, the strength of the drainage tube is affected, and the drainage tube is easy to damage; when the diameter is less than 2 mm, the drainage holes 31 are too thin, so that effusion and/or hematocele drainage is not smooth.

In some embodiments, the drainage manifold 3 has 6 to 12 branches, for example, 6, 7, 8, 9, 10, 11, or 12 branches. Fig. 3 shows that there are 8 drainage branches 3. The number of the branch drainage pipes 3 in the above range does not complicate the process, and the poor drainage effect due to too few branch drainage pipes 3 is not caused. The location of the branch drainage tube 3 on the outer surface of the balloon also makes the process simple.

In some embodiments, the branch drainage tubes 3 are uniformly distributed on the outer surface of the expansion balloon or embedded in the balloon wall 11 of the expansion balloon 1. So set up, the quantity of branch drainage pipe 3 can not make the technology complicated at above-mentioned within range, also can not arouse the drainage effect not good because branch drainage pipe 3 is too few. The location of the branch drainage tube 3 on the outer surface of the balloon also makes the process simple. The skilled person will appreciate that the branch drainage tubes 3 may be distributed uniformly over the outer surface of the balloon 1 or embedded in the wall 11 of the balloon 1 in the case of 6 to 12 tubes. The drainage effect is good because the drainage branch pipes 3 are uniformly distributed.

In some embodiments, each of the drainage legs 3 has a diameter of 5 mm to 8 mm. Under the condition that the diameter of the drainage branch pipe 3 is less than 5 mm, the drainage is not smooth, and hematocele and/or effusion can cause swelling, pain and the like; under the condition that the diameter of the drainage branch pipe 3 is larger than 8 mm, the drainage branch pipe 3 is too thick, occupies space, and is inconvenient and unnecessary.

In some embodiments, referring to fig. 2, the inflatable bladder 1 is spherical in shape in the second state. So set up, can be better fill in the bone cavity plays the effect of hemostasis by compression. Meanwhile, the accumulated liquid/blood in the bone cavity can be better drained.

In some embodiments, referring to fig. 1 and 2, the negative pressure drainage device 5 includes a negative pressure ball including a negative pressure lumen, the negative pressure ball is pressed to make the negative pressure lumen generate negative pressure to suck out hematocele and/or effusion between the expansion bladder 1 and the bone cavity of the maxillary and mandibular cysts, and the volume of the negative pressure lumen is 50 ml to 150 ml, such as 50 ml, 55 ml, 60 ml, 62 ml, 66 ml, 68 ml, 70 ml, 74 ml, 75 ml, 78 ml, 80 ml, 85 ml, 90 ml, 92 ml, 98 ml, 100 ml, 105 ml, 110 ml, 112 ml, 115 ml, 118 ml, 120 ml, 123 ml, 125 ml, 130 ml, 132 ml, 135 ml, 138 ml, 140 ml, 145 ml or 150 ml. So set up, negative pressure drainage device 5 can not only be with hematocele and/or hydrops suction, moreover, the volume of negative pressure inner chamber is 50 ml ~ 150 ml makes the suction of pressing negative drainage device 5 production appropriate, is difficult to produce painful uncomfortable and feels. In some embodiments, the negative pressure drainage device can be provided with scales, so that the amount of hematocele and/or effusion can be known through the scales, the amount of hemorrhage and the operation effect of a patient can be judged according to the amount of hematocele and/or effusion in the negative pressure drainage device, and an accurate basis is provided for evaluating the operation curative effect. In some embodiments, in order to easily press the negative pressure drainage device 5, the material of the cavity wall of the negative pressure drainage device 5 is silica gel.
