Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, and more specifically, to a continuous irrigation system for fungal sinusitis. Background Technology

[0002] Fungal sinusitis is a common and frequently occurring disease in otolaryngology. The maxillary sinus is the most frequently affected sinus, and it usually affects one side only. Surgery is the only way to treat it. The routine surgical procedure is as follows: open the maxillary sinus, enlarge the natural opening of the maxillary sinus, and use maxillary sinus grasping forceps combined with a suction device to irrigate. The purpose is to thoroughly clean the fungal masses in the maxillary sinus that resemble mud, silt, or fecal stones to prevent recurrence.

[0003] There are three major challenges in current maxillary sinus fungal debridement surgery: First, the 70° nasal endoscope is easily contaminated, requiring repeated removal and wiping. Furthermore, the instruments and endoscope are difficult to coordinate in the narrow nasal cavity, often requiring blind grasping by feel, which can easily damage the mucosa or lead to debridement failure. Second, the irrigation method is inefficient, requiring frequent changes of syringes, making the process lengthy. Third, there is a risk of leaving behind the gauze strips used to pack the unaffected nasal cavity to prevent the spread of infection to the healthy side.

[0004] Therefore, we have made improvements to this and proposed a continuous irrigation system for fungal sinusitis. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a continuous irrigation system for fungal sinusitis.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0007] A continuous irrigation system for fungal sinusitis includes a peristaltic pump with a pump head located below the front surface of the pump. An irrigation assembly is located on one side of the pump head. The irrigation assembly includes an irrigation conduit disposed within the pump head. One end of the irrigation conduit is equipped with an irrigation head assembly, which includes a first bend, a second bend, and a third bend. The first bend is fixedly installed at one end of the irrigation conduit. The inner wall of the first bend has a second bend that is retractably fitted into the outlet end of the first bend. The inner wall of the second bend has a third bend that is retractably fitted into the outlet end of the second bend.

[0008] As a preferred technical solution of this application, the axial extension and retraction of the second bend section relative to the first bend section and the third bend section relative to the second bend section can continuously adjust the relative distance and spatial orientation between the outlet end of the third bend section and the inlet end of the first bend section.

[0009] As a preferred technical solution of this application, a handle is fixedly connected to the middle of the flushing pipeline, and an injection catheter is fixedly connected below the handle.

[0010] As a preferred technical solution of this application, the middle part of the injection catheter is provided with a detection airbag, and the other part of the injection catheter is fixedly connected to an injection port.

[0011] As a preferred technical solution of this application, an auxiliary conduit is fixedly connected above the handle, and an air-filled bladder is fixedly connected to the end of the auxiliary conduit away from the handle.

[0012] As a preferred technical solution of this application, the other end of the pump head is provided with an extraction component. The extraction component includes an extraction pipeline movably installed on the other side of the pump head. One end of the extraction pipeline is fixedly connected to a T-tube, and both ends of the T-tube are fixedly connected to side tubes. The tail end of the side tube is fixedly connected to a puncture device.

[0013] As a preferred technical solution of this application, a branch tube is fixedly connected to the middle side wall of the puncture device, and a gas filter cap is fixedly connected to the end of the branch tube.

[0014] As a preferred technical solution of this application, a regulator is sleeved in the middle of the outer wall of the flushing pipeline to change the cross-sectional area of ​​the flow channel or the on / off state of the flushing pipeline.

[0015] As a preferred technical solution of this application, the tip of the puncture device is constructed in the shape of a spike, and a through hole for attracting liquid is formed on the spike-shaped structure.

[0016] As a preferred technical solution of this application, a display screen is provided above the front surface of the peristaltic pump, and several control buttons are evenly distributed in a straight line below the display screen.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) The present invention uses multiple curved pipe sections for connection and can be extended and retracted. With flushing heads at different angles, it can flush each wall of the maxillary sinus. The continuous or pulsed water flow can form a vortex in the maxillary sinus, which can "sweep away" the sticky and strongly adhesive fungi without damaging the sinus mucosa and avoid retrograde infection.

[0019] (2) In this invention, two puncture instruments are inserted into 3L of irrigation fluid, and a peristaltic pump provides power. The irrigation fluid is driven to flow in pulse mode or continuous mode, so as to provide sufficient irrigation fluid to the irrigation tubing, thereby shortening the operation time for cleaning fungi in the sinuses and improving the efficiency of the operation.

[0020] (3) The present invention improves the traditional filling method by inserting the filling airbag into the healthy nasal cavity and filling it with the inflating airbag, thus avoiding the problem of gauze residue. Attached Figure Description

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0027] As described in the background section, traditional maxillary sinus fungal debridement surgery faces multiple obstacles, including easy contamination of the nasal endoscope, poor coordination of instrument operation, low irrigation efficiency, and easy retention of gauze packing, resulting in inefficient and high-risk surgical procedures.

[0028] To address this technical problem, the present invention provides a continuous irrigation system for fungal sinusitis, which is applied in the field of medical auxiliary device technology.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] Example 1

[0031] Please refer to Figure 1 , Figure 2 and Figure 4 A continuous irrigation system for fungal sinusitis includes a peristaltic pump 1, a pump head 2 located below the front surface of the peristaltic pump 1, and an irrigation assembly on one side of the pump head 2. The irrigation assembly includes an irrigation conduit 5 disposed in the pump head 2, and an irrigation head assembly located at one end of the irrigation conduit 5. The irrigation head assembly includes a first bent section 14, a second bent section 15, and a third bent section 16. The first bent section 14 is fixedly installed at one end of the irrigation conduit 5. The inner wall of the first bent section 14 has the second bent section 15, which is retractably fitted into the outlet end of the first bent section 14. The inner wall of the second bent section 15 has the third bent section 16, which is retractably fitted into the outlet end of the second bent section 15. The axial extension and retraction of the second bend section 15 relative to the first bend section 14 and the third bend section 16 relative to the second bend section 15 can continuously adjust the relative distance and spatial orientation between the outlet end of the third bend section 16 and the inlet end of the first bend section 14. The peristaltic pump 1 works, and the flushing liquid flows along the flushing pipe 5, passes through the handle 8, and is discharged from the flushing head assembly. During the flushing process, the original state is the first bend section 14, which provides water flow in a 90-degree direction. Stretching the second bend section 15 can provide water flow in a 45-degree direction, and stretching the third bend section 16 can provide water flow in a 30-degree direction, thereby adjusting the water flow angle as needed.

[0032] The flushing head at different angles can reach all walls of the maxillary sinus, and the continuous or pulsating water flow can create eddies within the maxillary sinus, "swept away" the sticky and highly adhesive fungi without damaging the sinus mucosa and preventing retrograde infection.

[0033] Furthermore, such as Figure 2 As shown, a handle 8 is fixedly connected to the middle of the flushing tubing 5, and an injection catheter 9 is fixedly connected below the handle 8. A detection balloon 10 is provided in the middle of the injection catheter 9, and an injection port 11 is fixedly connected to the other end of the injection catheter 9. An auxiliary catheter 12 is fixedly connected above the handle 8, and a filling balloon 13 is fixedly connected to the end of the auxiliary catheter 12 away from the handle 8. When the filling balloon 13 is not filled with gas, its initial state is the same as the diameter of the auxiliary catheter 12 to facilitate placement. The filling balloon 13 is placed into the healthy nasal cavity to the nasopharynx. A syringe is connected to the injection port 11 to fill the filling balloon 13 with gas and inflate it to close the healthy nasal cavity. Since the filling balloon 13 and the monitoring balloon are interconnected, the monitoring balloon can ensure that the filling balloon 13 is within a safe pressure range.

[0034] Example 2

[0035] The continuous irrigation system for fungal sinusitis provided in Example 1 has been further optimized, specifically, as follows: Figure 1 and Figure 3As shown, the pump head 2 is provided with an extraction assembly at the other end. The extraction assembly includes an extraction pipe 6 movably installed on the other side of the pump head 2, and the extraction pipe 6 is connected to the flushing pipe 5. One end of the extraction pipe 6 is fixedly connected to a three-way pipe 18, and the other two ends of the three-way pipe 18 are fixedly connected to side pipes 17. The tail end of the side pipe 17 is fixedly connected to a puncture device 20. The tip of the puncture device 20 is constructed as a spike, and a through hole for aspirating liquid is opened on the spike structure. When two puncture devices 20 are inserted into 3L of flushing liquid, the peristaltic pump 1 works, and the flushing liquid enters the flushing pipe 5 along the extraction pipe 6.

[0036] By inserting two puncture instruments 20 into 3L of irrigation fluid, and using a peristaltic pump 1 to provide power, sufficient irrigation fluid is supplied to the irrigation tubing 5, thereby shortening the operation time for cleaning fungi in the sinuses and improving the efficiency of the operation.

[0037] Furthermore, such as Figure 3 As shown, a branch tube 19 is fixedly connected to the middle side wall of the puncture device 20, and a gas filter cover 21 is fixedly connected to the end of the branch tube 19. A regulator 7 is sleeved on the middle of the outer wall of the flushing pipe 5, which is used to change the cross-sectional area of ​​the flow channel of the flushing pipe 5 or the on / off state.

[0038] Furthermore, such as Figure 1 As shown, a display screen 3 is provided above the front surface of the peristaltic pump 1, and several control buttons 4 are evenly distributed in a straight line below the display screen 3. The peristaltic pump 1 is adjusted by controlling the control buttons 4, and the real-time parameters of the peristaltic pump 1 are viewed on the display screen 3. The peristaltic pump 1 can be switched between continuous mode and pulse mode.

[0039] The usage process of the continuous irrigation system for fungal sinusitis provided by this invention is as follows:

[0040] Working principle: Medical staff insert two puncture instruments 20 into 3L of irrigation fluid, press the control button 4 to adjust the working status of the peristaltic pump 1, and view the status on the display screen 3. After adjustment, the filling balloon 13 is placed into the healthy nasal cavity to the nasopharynx. A syringe is connected to the injection tube 11 to inflate the filling balloon 13 with gas, thus sealing the healthy nasal cavity. Since the filling balloon 13 is interconnected with the monitoring balloon, the monitoring balloon ensures that the filling balloon 13 is within a safe pressure range. After protecting the healthy nasal cavity, the peristaltic pump 1 starts working. The flushing fluid flows along the flushing pipe 5, passes through the handle 8, and is discharged from the flushing head assembly. During the flushing process, the initial state is the first bend section 14, which provides water flow in a 90-degree direction. The second bend section 15 is extended to provide water flow in a 45-degree direction, and the third bend section 16 is extended to provide water flow in a 30-degree direction. The water flow angle can be adjusted as needed. After adjusting to the appropriate angle, the continuous or pulsating water flow can form a vortex in the maxillary sinus, "sweeping away" the sticky and strongly adhering fungi without damaging the sinus mucosa.
