请参阅图1-4，支撑装置1000包括弹性球囊1和导管2。弹性球囊1套设于导管2的第一端，弹性球囊1与导管2的第一端的外壁共同围合有膨胀腔11。导管2用于支撑弹性球囊1和将膨胀腔11与外界连通，当通过导管2向膨胀腔11内注入流体时，弹性球囊1膨胀后体积变大，当通过注射通道21将膨胀腔11内流体抽出时，弹性球囊1收缩后体积变小。在进行鞍底修复时，将鞍隔b的破损处使用填充材料封堵后，将导管2套设有弹性球囊1的第一端插入蝶窦a中，通过导管2向膨胀腔11内注入流体时弹性球囊1膨胀后体积变大，弹性球囊1抵接于填充材料起支撑填充材料的作用。Referring to FIGS. 1-4 , thesupport device 1000 includes anelastic balloon 1 and acatheter 2 . Theelastic balloon 1 is sleeved on the first end of thecatheter 2 , and theelastic balloon 1 and the outer wall of the first end of thecatheter 2 together enclose anexpansion cavity 11 . Thecatheter 2 is used to support theelastic balloon 1 and connect theinflation chamber 11 with the outside world. When fluid is injected into theinflation chamber 11 through thecatheter 2, the volume of theelastic balloon 1 becomes larger after inflation. When theinflation chamber 11 is injected through theinjection channel 21 When the inner fluid is drawn out, the volume of theelastic balloon 1 becomes smaller after being contracted. When performing saddle bottom repair, the damaged part of the saddle septum b is sealed with a filling material, then the first end of thecatheter 2 sheathed with theelastic balloon 1 is inserted into the sphenoid sinus a, and injected into theinflation cavity 11 through thecatheter 2 In the case of fluid, the volume of theelastic balloon 1 becomes larger after being expanded, and theelastic balloon 1 abuts against the filling material to support the filling material.

在本实施例中，流体使用生理溶液，当弹性球囊1破损导致生理溶液泄露时，不会对病人造成二次伤害。In this embodiment, a physiological solution is used as the fluid, and when theelastic balloon 1 is damaged and the physiological solution leaks, it will not cause secondary damage to the patient.

The material of theelastic balloon 1 is silica gel. It can be understood that the material of theelastic balloon 1 can also be plastics such as PVC, latex, and TPE.

在本实施例中，导管2设置有注射通道21，注射通道21的第一端设置于导管2的第一端，注射通道21的第一端设置有侧孔211。注射通道21的第二端设置于导管2的第二端，注射通道21的第二端与外界连通。导管2采用的材料为硅胶，可以理解的是，导管2的材料还可以为PVC、乳胶和TPE等材料。In this embodiment, thecatheter 2 is provided with aninjection channel 21 , the first end of theinjection channel 21 is provided at the first end of thecatheter 2 , and the first end of theinjection channel 21 is provided with aside hole 211 . The second end of theinjection channel 21 is disposed on the second end of theconduit 2 , and the second end of theinjection channel 21 communicates with the outside world. The material used for thecatheter 2 is silica gel. It can be understood that the material of thecatheter 2 can also be PVC, latex, TPE and other materials.

在本实施例中，导管2的第一端插入第一通孔12，沿第一通孔12的轴向，弹性球囊1的两端分别与导管2的外壁密封连接，弹性球囊1与导管2的外壁围合形成膨胀腔11。侧孔211贯穿导管2的侧壁，侧孔211连通注射通道21和膨胀腔11。沿第一通孔12的轴向，导管2的第一端的端面不凸出于弹性球囊1。将导管2的第一端送入蝶窦a后，导管2的第一端的端面朝向鞍隔b的破损处，通过位于导管2的第二端的注射通道21的入口向膨胀腔11内注射流体，流体从注射通道21的第二端流向注射通道21的第一端，经侧孔211流入膨胀腔11内，使弹性球囊1膨胀体积变大，环绕在导管2的第一端的端面周围的弹性球囊1抵接于鞍隔b破损处的填充材料，以支撑填充材料，使填充材料稳固地保持在鞍隔b破损的位置，避免填充材料移位、脱落导致鞍隔b破损处再次出现缺口造成脑脊液外漏。由于导管2的第一端的端面不凸出于弹性球囊1，避免导管2的第一端的端面与填充材料干涉，导致填充材料产生位移。In this embodiment, the first end of thecatheter 2 is inserted into the first throughhole 12 , and along the axial direction of the first throughhole 12 , both ends of theelastic balloon 1 are sealed and connected to the outer wall of thecatheter 2 respectively. The outer wall of thecatheter 2 forms anexpansion cavity 11 . Theside hole 211 penetrates the side wall of thecatheter 2 , and theside hole 211 communicates with theinjection channel 21 and theinflation cavity 11 . Along the axial direction of the first throughhole 12 , the end face of the first end of thecatheter 2 does not protrude from theelastic balloon 1 . After the first end of thecatheter 2 is sent into the sphenoid sinus a, the end face of the first end of thecatheter 2 faces the damage of the septum b, and the fluid is injected into theinflation cavity 11 through the inlet of theinjection channel 21 at the second end of thecatheter 2 , the fluid flows from the second end of theinjection channel 21 to the first end of theinjection channel 21 , and flows into theinflation cavity 11 through theside hole 211 , so that the inflation volume of theelastic balloon 1 becomes larger and surrounds the end face of the first end of thecatheter 2 Theelastic balloon 1 is in contact with the filling material at the damaged part of the saddle septum b to support the filling material, so that the filling material can be stably maintained at the damaged position of the saddle septum b, so as to avoid the displacement and falling off of the filling material, which may cause the damaged part of the saddle septum b to be regenerated again. There is a gap causing cerebrospinal fluid to leak out. Since the end surface of the first end of thecatheter 2 does not protrude from theelastic balloon 1 , it is avoided that the end surface of the first end of thecatheter 2 interferes with the filling material, resulting in displacement of the filling material.

进一步的，导管2还设置有分支部22和引流通道23。分支部22的第一端与导管2第二端的侧壁连接，注射通道21的第二端设置于分支部22的第二端。引流通道23的第一端设置于导管2的第一端，引流通道23的第一端与外界连通，引流通道23的第一端与外界连通的出口设置于导管2的第一端的端面。引流通道23的第二端设置于导管2的第二端，引流通道23的第二端与外界连通，引流通道23的第二端与外界连接的出口设置于导管2的第二端的端面。支撑装置1000还包括有密封盖3，密封盖3盖设于导管2的第二端的端面，以封闭引流通道23的第二端。Further, theconduit 2 is also provided with a branch portion 22 and adrainage channel 23 . The first end of the branch portion 22 is connected to the side wall of the second end of theconduit 2 , and the second end of theinjection channel 21 is disposed at the second end of the branch portion 22 . The first end of thedrainage channel 23 is arranged on the first end of theconduit 2 , the first end of thedrainage channel 23 communicates with the outside world, and the outlet where the first end of thedrainage channel 23 communicates with the outside world is arranged on the end face of the first end of theconduit 2 . The second end of thedrainage channel 23 is arranged on the second end of theconduit 2 , the second end of thedrainage channel 23 communicates with the outside world, and the outlet connecting the second end of thedrainage channel 23 with the outside world is arranged on the end face of the second end of theconduit 2 . Thesupport device 1000 further includes a sealing cover 3 , and the sealing cover 3 is covered on the end face of the second end of theconduit 2 to close the second end of thedrainage channel 23 .

当弹性球囊1朝向鞍隔b的一端的端面抵接于鞍隔b破损处的填充材料时，鞍隔b破损处有脑脊液外漏，外漏的脑脊液可沿经引流通道23的第二端进入引流通道23中。通过引流通道23是否有脑脊液流出，可以判断鞍底修复的情况，若引流通道23持续有脑脊液排出，说明鞍隔b破损处仍未修复到位。When the end face of theelastic balloon 1 facing the saddle septum b is in contact with the filling material at the damaged part of the saddle septum b, there is cerebrospinal fluid leakage at the damaged part of the saddle septum b, and the leaked cerebrospinal fluid can pass through the second end of thedrainage channel 23 into thedrainage channel 23 . Whether there is cerebrospinal fluid flowing out of thedrainage channel 23 can determine the condition of the saddle bottom repair. If thedrainage channel 23 continues to discharge cerebrospinal fluid, it means that the damaged part of the saddle septum b has not been repaired in place.

再进一步的，支撑装置1000还包括指示气囊4、耳挂5和套环6。指示气囊4设置有指示腔41，指示气囊4的第一端与分支部22的第二端连接，注射通道21的第二端与指示腔41连通，指示气囊4的第二端设置有第二通孔42，第二通孔42将指示腔41与外界连通。流体依次通过第二通孔42、指示腔41和注射通道21后进入膨胀腔11，由于指示腔41与膨胀腔11连通，当弹性球囊1膨胀体积变大时，指示气囊4也同时膨胀体积变大，当将流体抽出时，弹性球囊1和指示气囊4同时收缩体积变小，通过观察指示气囊4的膨胀和收缩情况，可判断弹性球囊1的膨胀和收缩情况。耳挂5的一端与导管2的第二端连接，耳挂5的第二端自耳挂5的第一端朝向导管2的第一端方向弯折后延伸得到。套环6与耳挂5的第一端连接，套环6套设于导管2的第二端，使耳挂5固定于导管2的第二端。当将导管2套设有弹性球囊1的第一端插入病人的蝶窦a中后，耳挂5可挂设于病人的一侧耳朵处。Still further, thesupport device 1000 also includes an indicator air bag 4 , anear loop 5 and aloop 6 . The indicating airbag 4 is provided with an indicatingcavity 41, the first end of the indicating airbag 4 is connected with the second end of the branch portion 22, the second end of theinjection channel 21 is communicated with the indicatingcavity 41, and the second end of the indicating airbag 4 is provided with a second end The throughhole 42 and the second throughhole 42 communicate the indicatingcavity 41 with the outside world. The fluid passes through the second throughhole 42, the indicatingcavity 41 and theinjection channel 21 in sequence and then enters theexpansion cavity 11. Since the indicatingcavity 41 is in communication with theexpansion cavity 11, when the expansion volume of theelastic balloon 1 increases, the indicating balloon 4 also expands its volume at the same time. When the fluid is drawn out, theelastic balloon 1 and the indicating balloon 4 shrink in volume at the same time. By observing the expansion and contraction of the indicating balloon 4, the expansion and contraction of theelastic balloon 1 can be judged. One end of theearhook 5 is connected to the second end of theconduit 2 , and the second end of theearhook 5 is bent and extended from the first end of theearhook 5 toward the first end of theconduit 2 . Thecollar 6 is connected to the first end of theear hook 5 , and thecollar 6 is sleeved on the second end of thecatheter 2 , so that theear hook 5 is fixed on the second end of thecatheter 2 . When the first end of thecatheter 2 sheathed with theelastic balloon 1 is inserted into the patient's sphenoid sinus a, theear hook 5 can be hung on one side of the patient's ear.

当进行鞍底修复时，使用填充材料封堵鞍隔b破损处后，将支撑装置1000具有弹性气囊的一端经病人鼻腔后插入蝶窦a内，此时指示气囊4位于病人鼻孔外附近，过观察指示气囊4可判断弹性气囊的膨胀和收缩情况；使用无针注射器吸取生理溶液后，将无针注射器的注射口插入第二通孔42，通过第二通孔42将生理溶液注入膨胀腔11内，以使弹性球囊1膨胀后体积变大，导管2的第一端的端面朝向鞍隔b破损处，弹性球囊1朝向鞍隔b破损处的一端的端面抵接鞍隔b破损处的填充材料，弹性球囊1环绕导管2的侧壁的侧面抵接于蝶窦a的内壁，使弹性球囊1固定在蝶窦a内；将耳挂5挂在病人的一侧耳朵上，将支撑装置1000固定，防止导管2移动造成支撑装置1000失效。在使用完成后，使用无针注射器将膨胀腔11内的生理溶液抽出，弹性气囊收缩体积变小，此时可将支撑装置1000从病人的蝶窦a中取出。When the saddle bottom is repaired, after sealing the damaged part of the septum b with a filling material, insert the end of thesupport device 1000 with an elastic air bag into the sphenoid sinus a through the patient's nasal cavity. The expansion and contraction of the elastic airbag can be judged by observing the indicating airbag 4; after using the needleless syringe to absorb the physiological solution, insert the injection port of the needleless syringe into the second throughhole 42, and inject the physiological solution into theinflation cavity 11 through the second throughhole 42 In order to make the volume of theelastic balloon 1 become larger after inflation, the end face of the first end of thecatheter 2 faces the damaged part of the saddle septum b, and the end face of the end face of theelastic balloon 1 facing the damaged part of the saddle septum b abuts against the damaged part of the saddle septum b The side wall of theelastic balloon 1 surrounding the side wall of thecatheter 2 abuts on the inner wall of the sphenoid sinus a, so that theelastic balloon 1 is fixed in the sphenoid sinus a; theear hook 5 is hung on one side ear of the patient, Thesupport device 1000 is fixed to prevent thesupport device 1000 from failing due to movement of thecatheter 2 . After the use is completed, the physiological solution in theinflation chamber 11 is drawn out by using a needleless syringe, and the shrinkage volume of the elastic balloon becomes smaller. At this time, thesupport device 1000 can be taken out from the sphenoid sinus a of the patient.
