Technical Field
[0001] This invention belongs to the field of medical technology, and in particular relates to a sinus ostium stent manufacturing system and method. Background Technology
[0002] The sinuses, also known as paranasal sinuses or accessory sinuses, are multiple air-filled bony cavities surrounding the nasal cavity. The mucous membranes of the sinuses are connected to the nasal mucosa, so inflammation of the nasal mucosa often affects the sinus mucosa, causing sinusitis. Currently, it is believed that the main cause of sinusitis is infection within the sinuses due to obstruction of the sinus openings caused by various reasons. Nasal polyps are an important cause of sinus opening obstruction, and the inflammation of the sinuses, in turn, promotes the growth of nasal polyps, forming a vicious cycle. There are various treatment options for sinus diseases in existing technologies. In the treatment process, sinus ostium stents are a commonly used medical device. However, there are still shortcomings in the manufacturing process of sinus ostium stents. When cleaning and processing the pre-formed sinus ostium stents, it is not convenient to independently clean different types of individual sinus ostium stents, resulting in poor cleaning effects. Summary of the Invention

[0009] Step 2: If the sinus ostium stent is a fixed and unchangeable stent, connect the connecting ring to the outer cover by tightening the bolts, and then insert the fixed and unchangeable stent into the outer cover.
[0010] Step 3: Slide the skateboard upwards, which will cause the clamps on the skateboard to apply a pushing force to the bottom of the bracket, thus pushing the bracket against the upper end of the inner wall of the outer cover;
[0011] Step 4: Move the robotic arm downwards to submerge the outer cover below the surface of the cleaning water in the container below, and begin cleaning the support structure that cannot be changed.
[0012] Step 5: If the sinus ostium stent to be cleaned is a self-expanding stent with a variable structure, after placing the stent inside the outer cover, fix the upper end of the stent to the upper end of the inner wall of the outer cover.

[0027] See Figure 1-4 The diagram illustrates an embodiment of the present invention that enables independent cleaning of individual sinus ostium stents of different types, thereby improving the cleaning effect. Further,
[0028] The system includes a fixed rod 101, a base frame 102 connected to the fixed rod 101, a sliding plate 201 slidably connected to the base frame 102, a clamping plate 202 connected to the sliding plate 201, an outer cover 401 fixedly connected to the base frame 102, a plurality of water passage holes 402 opened on the outer cover 401, a connecting ring 301 detachably connected inside the outer cover 401, a plurality of skin-like adhesive strips 302 fixedly connected inside the connecting ring 301, a first auxiliary plate 405 slidably connected to the outer cover 401, the first auxiliary plate 405 can be fixed to the outer cover 401 by bolts, a first electric push rod that can push the sliding plate 201 to slide is fixedly connected to the base frame 102, the fixed rod 101 is connected to a vertically movable robotic arm by screwing bolts into the fixed rod 101, and a container filled with flowing cleaning water is installed directly below the device. The first auxiliary plate 405 is made of magnetic material and can attract the support.
[0029] Take a sinus ostium stent to be cleaned. If the stent has a fixed structure that cannot be changed, connect the connecting ring 301 to the outer cover 401 by tightening the bolts. Then, insert the fixed stent into the outer cover 401, so that the stent is firmly pressed against the multiple skin-like adhesive strips 302 on the connecting ring 301. This simulates the state of the stent being inserted into the nasal cavity. If the stent does not slip out of the outer cover 401, it proves that the material and size of the stent meet the usage requirements. Otherwise, it proves that it is easy to slip out when inserted into the patient's nasal cavity, and further processing is required. To ensure the finished product effect, the slide plate 201 is then slid upwards, causing the clamping plate 202 on the slide plate 201 to apply a pushing force to the bottom of the bracket, which then presses the bracket tightly against the upper end of the inner wall of the outer cover 401. The bracket is then clamped and fixed by the clamping plate 202 and the inner wall of the outer cover 401. Then, the robot arm is moved downwards, submerging the outer cover 401 below the surface of the cleaning water in the container below. The cleaning water in the container flows continuously, causing the cleaning water to flow into the outer cover 401 through multiple water holes 402, thereby rinsing and cleaning the bracket that is fixed and cannot be moved within the outer cover 401.
[0030] To further improve the cleaning effect, after using the connecting ring 301 to conduct a simulation test on the support with a fixed structure that cannot be changed, the connecting ring 301 can be removed from the outer cover 401, and then the clamp 202 can be used to clamp the support to further improve the cleaning effect.
[0031] If the sinus stent to be cleaned is a self-expanding stent with a variable structure, after placing the stent inside the outer cover 401, the upper end of the stent is fixed to the upper inner wall of the outer cover 401. Then, the first auxiliary plate 405 is gradually slid into the outer cover 401, thereby gradually pushing the movable part below the stent and causing the stent to gradually expand. The first auxiliary plate 405 is then fixed by tightening bolts, simulating the state of the stent inserted into the nasal cavity and fully expanding the stent. When the cleaning water flows through the stent, it can more easily and completely contact all parts of the stent, improving the cleaning effect. At the same time, because the first auxiliary plate... 405 is made of magnet material, which can attract the bracket, thereby allowing the first auxiliary plate 405 to firmly attract and fix the movable parts below the bracket. This ensures that the bracket inside the outer cover 401 can be firmly fixed between the outer cover 401 and the first auxiliary plate 405 during the subsequent cleaning process, thus guaranteeing the subsequent cleaning effect. Then, the robot arm moves downward, immersing the outer cover 401 below the surface of the cleaning water in the container below. The cleaning water in the container continuously flows through the multiple water passages 402 on the outer cover 401, thereby thoroughly cleaning the self-expanding bracket with a variable structure held inside the outer cover 401.
[0032] The self-expanding support is a relatively mature type of support in the prior art. It consists of a round rod, a movable part that slides on the round rod, and multiple expansion bars fixed between the round rod and the movable part. By operating the movable part to slide upward on the round rod, the multiple expansion bars expand away from the round rod, thus completing the support function.
[0033] The fixed and unchangeable support structure is a type of support commonly used in the prior art, which is a cylinder with a through groove or other fixed-shape support.
[0034] See Figure 4 A schematic diagram of an embodiment of the invention that facilitates fixing the upper end of the self-expanding support is shown. Further,
[0035] It also includes a magnetic plate 403 fixed inside the outer cover 401.
[0036] After placing the self-expanding bracket inside the outer cover 401, the upper end of the self-expanding bracket can be attached to the magnetic plate 403, thereby firmly adsorbing and fixing the upper end of the self-expanding bracket through the magnetic plate 403. Then, the first auxiliary plate 405 is slid into the outer cover 401, and the first auxiliary plate 405 gradually pushes the movable part on the self-expanding bracket upward, thereby opening the self-expanding bracket. Then, the first auxiliary plate 405 is fixed, and the bracket is then firmly fixed inside the outer cover 401 in the opened position, which facilitates subsequent cleaning tasks.
[0037] See Figure 5-6 The diagram illustrates an embodiment of the improved cleaning effect according to the present invention. Further,
[0038] It also includes a connector 501 connected to the base frame 102, a drive plate 504 rotatably connected to the connector 501, a cleaning brush 502 detachably connected to the drive plate 504 by bolts, a first motor that can drive the drive plate 504 to slide is fixed to the connector 501, and the cleaning brush 502 can contact the surface of the outer cover 401.
[0039] After the outer cover 401 is submerged in the cleaning water, the cleaning brush 502 is continuously rotated, which causes the cleaning brush 502 to come into contact with the surface of the outer cover 401. The bristles on the cleaning brush 502 then enter the interior of the outer cover 401 through multiple water holes 402, thereby brushing the support inside the outer cover 401 and thus improving the cleaning effect.
[0040] After using the cleaning brush 502 for a period of time, if too much impurity adheres to the cleaning brush 502 or if the bristles on the cleaning brush 502 fall off severely, the cleaning brush 502 can be removed from the drive board 504 by loosening the bolts, and then the cleaning brush 502 can be replaced to ensure long-lasting cleaning effect.
[0041] See Figure 5-7 The diagram illustrates an embodiment of the invention that further improves the cleaning effect.
[0042] It also includes an arc-shaped slide rail 104 fixed to the base frame 102, a slide 503 slidably connected to the arc-shaped slide rail 104, a connector 501 slidably connected to the slide 503, and a first tension spring fixed between the slide 503 and the connector 501.
[0043] When the cleaning brush 502 is continuously rotated to improve the cleaning effect, the operable slide 503 slides on the arc-shaped slide rail 104, causing the slide 503 to move the connector 501, thereby adjusting the position of the cleaning brush 502 relative to the outer cover 401, increasing the area that the cleaning brush 502 can brush, and thus further improving the cleaning effect. Simultaneously, when the slide 503 slides to a certain position on the arc-shaped slide rail 104 and stops moving, the continuous rinsing of the flowing cleaning water and the continuous rotation of the cleaning brush 502 cause the connector 501 to be continuously impacted by external forces. This causes the connector 501 to spontaneously slide on the slide 503 against the elastic force of the first tension spring. After the slide 503 moves to a certain position, the connector 501 can cause the cleaning brush 502 to oscillate irregularly within a certain range, further improving the cleaning effect.
[0044] See Figure 2 The diagram illustrates an embodiment of the present invention that further facilitates the detection of the wearing state of a fixed, non-changing support within the nasal cavity and further improves the cleaning effect. Further,
[0045] The clamping plate 202 is rotatably connected to the slide plate 201. A rectangular groove is cut out at the lower end of the fixed support, and a rectangular block is fixed to the clamping plate 202. A second motor that can drive the clamping plate 202 to rotate is fixed to the slide plate 201.
[0046] The fixed and unchangeable bracket is inserted into the outer cover 401, and the outer wall of the bracket is pressed tightly against multiple skin-like adhesive strips 302. Then, when the sliding plate 201 is slid upward, the rectangular block on the clamp 202 can be inserted into the rectangular groove at the lower end of the fixed and unchangeable bracket. Then, the clamp 202 is rotated, which in turn drives the bracket to rotate inside the outer cover 401. Then, the sliding plate 201 is slid downward. If the bracket slides downward synchronously with the clamp 202 at this time, it proves that the installation effect of the bracket in the patient's nasal cavity is still not good enough and additional processing is required. Otherwise, it proves that the bracket meets the factory requirements.
[0047] During the cleaning process, the clamping plate 202 can be operated to slide slightly downwards periodically to reduce the clamping force on the bracket. Then, the clamping plate 202 can be rotated at a certain angle to periodically change the clamping posture of the bracket, thereby further improving the cleaning effect.
[0048] See Figure 4-5 The diagram illustrates an embodiment of the invention for further detecting the wearing state of a fixed, non-changing support within the nasal cavity. Further,
[0049] It also includes a rotating sleeve 601 connected to the base frame 102. A second auxiliary plate 602 is rotatably connected to the rotating sleeve 601. A circular hole 604 is opened on the second auxiliary plate 602. A blower is fixedly connected to the second auxiliary plate 602. The air outlet of the blower communicates with the circular hole 604. Multiple through holes 404 are opened on the outer cover 401. A third motor is fixedly connected to the rotating sleeve 601. A gear is fixedly connected to the output shaft of the first motor. A gear ring is fixedly connected to the second auxiliary plate 602. The gear meshes with the gear ring.
[0050] After the fixed and unchangeable bracket is inserted into the outer cover 401 and the outer wall of the bracket is pressed tightly against multiple skin-like adhesive strips 302, the blower can slowly blow out gas, and the second auxiliary plate 602 gradually rotates on the rotating sleeve 601. Then, the gas gradually blows into the outer cover 401 through multiple through holes 404, thereby providing downward blowing force to the fixed and unchangeable bracket inside the outer cover 401. This further allows for the detection of the fixed and unchangeable bracket's wearing status in the nasal cavity, ensuring the yield rate.
[0051] See Figure 5 , Figure 7 The diagram illustrates an embodiment of the invention that further improves the detection effect and facilitates the sliding of the carriage 503. Further,
[0052] The rotating sleeve 601 is slidably connected to the base frame 102. An insert plate 603 is fixedly connected to the second auxiliary plate 602. A slot is opened on the slide 503, and the insert plate 603 can be inserted into the slot. A rubber strip is fixedly connected at the sliding connection between the arc-shaped slide rail 104 and the slide 503. The rubber strip can increase the sliding friction of the slide 503, so that the slide 503 can be stably fixed in a certain position when it is not subjected to external force, which makes it easy for the insert plate 603 to be inserted into the slot on the slide 503.
[0053] When the blower slowly blows out the gas, the operable rotating sleeve 601 can slide on the base frame 102, thereby changing the distance between the gas source and the magnetic plate 403, and further improving the detection effect.
[0054] Simultaneously, when cleaning is required, the rotating sleeve 601 can be slid downwards, thereby allowing the insert plate 603 to be inserted into the slot of the carriage 503, forming a shape as shown. Figure 7 As shown in the posture, the second auxiliary plate 602 can still be used to slide back and forth during the cleaning process, so that the carriage 503 can slide continuously on the arc-shaped slide rail 104, thereby expanding the cleaning range of the cleaning brush 502 and improving the cleaning effect.
[0055] See Figure 7 A schematic diagram of an embodiment of the present invention that facilitates the sliding of the rotating sleeve 601 is shown. Further,
[0056] It also includes a pressure plate 701 that is slidably connected to the fixed rod 101, a second tension spring that is fixed between the rotating sleeve 601 and the base frame 102, and a second electric push rod that can drive the pressure plate 701 to slide that is fixed on the fixed rod 101. The elastic force of the second tension spring can make the rotating sleeve 601 tightly adhere to the lower end of the pressure plate 701.
[0057] By operating the pressure plate 701 to slide up and down, the pressure plate 701, in conjunction with the second tension spring, can operate the rotating sleeve 601 to slide up and down on the base frame 102, thereby achieving the two purposes of improving the detection effect and enhancing the cleaning effect.
[0058] See Figure 7-8 A schematic diagram of an embodiment for further enhancing the cleaning effect is shown.
[0059] It also includes an inclined plate 702 fixed to the pressure plate 701, a cylindrical rod 103 fixed to the base frame 102, the base frame 102 being slidably connected to the fixed rod 101, and a third tension spring being fixed between the fixed rod 101 and the base frame 102. The elastic force provided by the third tension spring allows the cylindrical rod 103 to always be in contact with the surface of the inclined plate 702.
[0060] When inserting the insert plate 603 into the slot on the carriage 503 and continuously rotating the second auxiliary plate 602 to improve the cleaning effect, the pressure plate 701 can be operated to slide up and down repeatedly, which in turn causes the inclined plate 702 to slide back and forth with the pressure plate 701. Since the elastic force provided by the third tension spring can keep the cylindrical rod 103 in contact with the surface of the inclined plate 702, the base frame 102 will slide back and forth on the fixed rod 101 during the up and down sliding of the pressure plate 701, which further facilitates the full contact between the cleaning water and the support, and further improves the cleaning effect.
