Description

Technical Field

[0001] This utility model relates to the field of maxillary sinus cyst technology, specifically a device for aspirating fluid from maxillary sinus cysts. Background Technology

[0002] Maxillary sinus cysts are a relatively common benign lesion of the maxillary sinus. Most cysts form due to fluid retention caused by periapical inflammation of teeth or blockage of the maxillary sinus mucous gland duct opening. Small cysts are usually asymptomatic, but as they grow larger, related clinical symptoms will appear. For maxillary sinus cysts caused by periapical inflammation, the cyst may persist even after tooth extraction. If a maxillary sinus cyst causes clinical symptoms, or if a maxillary sinus floor lift is required during implant surgery in the cyst area, the cyst needs to be removed or the cyst fluid aspirated to prevent excessively large cysts from blocking the maxillary sinus opening and causing infection of the maxillary sinus and implant surgery area. Aspiration of the cyst fluid preserves the integrity of the maxillary sinus membrane, which is beneficial for the sealing of bone graft material during maxillary sinus floor lift.

[0003] In general, a single syringe is used for aspiration of fluid from maxillary sinus cysts. While this allows for aspiration, it is difficult to completely remove the fluid. Furthermore, leakage is common during the procedure, posing a risk of infection. Additionally, the instruments used are not very safe or stable, and their high sensitivity makes them prone to puncturing the maxillary sinus membrane. Therefore, we have developed a maxillary sinus cyst aspiration device to address these issues. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a maxillary sinus cyst fluid aspiration device, comprising a double-tube syringe and a fixing mechanism. The double-tube syringe connects a connecting hose and a threaded cylinder via a connecting sleeve. The threaded cylinder is fixedly connected to the double-tube syringe. A stop ring is fitted onto the outer circumferential surface of the connecting hose. A connecting sleeve handle is fixedly connected to the outer circumferential surface of the connecting sleeve. The tight fit between the components allows for simultaneous aspiration and cleaning of the maxillary sinus cyst, thereby reducing the risk of infection.

[0006] Preferably, the fixing mechanism includes a control plate into which a dual-tube syringe is inserted, the control plate being configured to apply a positioning control effect to the dual-tube syringe.

[0008] Preferably, one end of the wing bolt is rotatably connected to a pressure plate, which contacts the double-tube syringe. The double-tube syringe allows for the smooth extraction of cyst fluid and irrigation fluid.

[0009] Preferably, a control rod is fixedly connected to one side of the pressure plate. There are two control rods in total. The setting of the control rods ensures the stability of the pressure plate.

[0010] Preferably, the outer circumferential surfaces of the two control rods are slidably connected to the inner wall of the control plate, and a spiral frame is fixedly connected to one side of the control plate. The spiral frame ensures the stability of the T-shaped support plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution for a maxillary sinus cyst fluid aspiration device, including a double-tube syringe 1 and a fixing mechanism 2. The fixing mechanism 2 is mainly used to fix the double-tube syringe 1, so that the double-tube syringe 1 is suspended in the air, thereby adapting to different working scenarios. The fixing mechanism 2 includes a control plate 201 into which the double-tube syringe 1 is inserted. The purpose of setting the control plate 201 is to apply a preliminary control effect to the double-tube syringe 1 and ensure the lateral stability of the double-tube syringe 1. The inner wall of the control plate 201 is threaded with a wing bolt 202. One end of the wing bolt 202 is rotatably connected to a pressure plate 203. The tight fit between the control plate 201 and the wing bolt 202 means that when the pressure plate 203 remains stable, the rotation of the wing bolt 202 will drive the pressure plate 203 to move horizontally.

[0025] A gooseneck tube 208 is fixedly connected to one side of the control plate 201. The gooseneck tube 208 has a metal spring or spiral steel wire inside and is covered with rubber, silicone or fabric on the outside. It can be bent 360° and fixed at an angle. A clip 209 is fixedly connected to one end of the gooseneck tube 208. The clip 209 can be used to place the fixation mechanism 2 on the operating cart.

[0026] A control rod 204 is fixedly connected to one side of the pressure plate 203. The pressure plate 203 and the control rod 204 maintain a linkage effect. The outer circumferential surfaces of the two control rods 204 are slidably connected to the inner wall of the control plate 201. The setting of the control rod 204 can effectively ensure the stability of the pressure plate 203, so that the pressure plate 203 can only move in the horizontal direction.

[0027] A U-shaped frame 205 is fixedly connected to one side of the control plate 201. The control plate 201 and the U-shaped frame 205 maintain a linkage effect. The U-shaped frame 205 is connected to a T-shaped support plate 207 by locking bolts 206. The purpose of setting the locking bolts 206 is to ensure that the T-shaped support plate 207 remains stable after movement by manually tightening the locking bolts 206.

[0028] There are two T-shaped support plates 207. The setting of two T-shaped support plates 207 ensures the overall stability of the fixing mechanism 2. There are two control rods 204. The setting of two control rods 204 enhances the stabilizing effect of the pressure plate 203. The pressure plate 203 contacts the double-tube syringe 1 and presses the double-tube syringe 1, thereby ensuring the stability of the double-tube syringe 1 and preventing the problem of parts falling off.

[0029] The dual-tube syringe 1 connects the connecting tubing 5 and the threaded sleeve 8 via the connecting sleeve 3. The threaded sleeve 8 is fixedly connected to the dual-tube syringe 1. Two tubular protrusions on the threaded sleeve 8 are inserted into the two openings of the connecting tubing 5, forming a communication relationship. The threaded sleeve 8 and the connecting sleeve 3 are threaded together. The connecting sleeve 3 prevents the connecting tubing 5 from coming loose inside the threaded sleeve 8 during irrigation and aspiration, ensuring that the irrigation fluid enters the cyst and that there is negative pressure during aspiration to smoothly draw out the cyst fluid and irrigation fluid. It also facilitates operation for the user and greatly improves the efficiency of disassembly and assembly. The connecting tubing 5 is 5-20cm long to meet the needs of different intraoral conditions. It is used to connect the dual-needle assembly 6 and the dual-tube syringe 1. The connecting tubing 5 contains reinforcing steel wire and is of medium hardness. It will not bend when the dual-needle assembly 6 is inserted into the cyst wall. After the dual-needle assembly 6 is inserted into the cyst wall, it can be bent by hand into any arc and maintain its shape without deformation to adapt to operation in various directions inside the oral cavity.

[0030] One end of the connecting tubing 5 is fixedly connected to a double-needle assembly 6, which consists of two needles, one long and one short. The needles have a 45° bevel, an inner diameter of 1.5 mm, a long needle diameter of 4 mm, and a short needle diameter of 2 mm. The short needle is used to aspirate cyst fluid, and the long needle is used to inject saline solution for irrigation. A stop ring 7 is fitted onto the outer circumference of the connecting tubing 5. The stop ring 7 prevents the double-needle assembly 6 from being inserted too deeply into the cyst wall when it is inserted into the cyst. At the same time, it can apply gentle pressure to stabilize the double-needle assembly 6 within the cyst and prevent it from dislodging. A connecting sleeve handle 4 is fixedly connected to the outer circumference of the connecting sleeve 3. The connecting sleeve handle 4 is designed to connect and disconnect the connecting tubing 5 and the double-tube syringe 1 when the short injection tube has finished injecting the irrigation fluid or when the long injection tube has been filled with aspirated fluid. This allows for the replacement of fresh saline solution and the repetition of irrigation and aspiration operations.

[0031] Working principle: During use, the double-needle assembly 6 is inserted into the maxillary sinus cyst. The stop ring 7 prevents excessive insertion and puncture of the cyst wall while inserting the double-needle assembly 6 into the cyst. Simultaneously, gentle pressure is applied to stabilize the double-needle assembly 6 within the cyst, preventing needle dislodgement. Finally, the thumb pushes the plunger of the short injection tube of the double-tube syringe 1, while the other four fingers pull back the plunger of the long injection tube of the double-tube syringe 1, simultaneously completing flushing and aspiration. When the flushing fluid in the short injection tube is finished or the long injection tube is full of aspirated fluid, the external force... Under the influence of the sound, the connecting sleeve 3 is rotated by the connecting sleeve handle 4, thereby pulling the connecting hose 5 out of the threaded sleeve 8, allowing for the replacement of fresh saline solution. The flushing and aspiration operations are repeated. The use of the fixing mechanism 2 can be chosen freely depending on the specific application scenario. When using the fixing mechanism 2, the double-tube syringe 1 is inserted into the control plate 201 from bottom to top. By manually turning the butterfly bolt 202, the control rod 204, which is connected to the pressure plate 203, will be subjected to the pressure of the control plate 201. Due to the limitation of 01, the rotation of the butterfly bolt 202 will push the pressure plate 203 to move, so that the pressure plate 203 contacts the double-tube syringe 1. Under the action of pre-tightening force and friction, the stability of the double-tube syringe 1 is ensured, that is, the double-tube syringe 1 is installed in the fixing mechanism 2. Then, by manual force, the T-shaped support plate 207 moves 90 degrees around the locking bolt 206 as the axis. When the T-shaped support plate 207 is in a vertical state, tightening the locking bolt 206 can ensure the stability of the T-shaped support plate 207, so that the fixing mechanism 2 can be placed flat in the designated position, so that the double-tube syringe 1 is in a suspended state, which makes it easier for the user to operate the double-tube syringe 1. At the same time, the fixing mechanism 2 can be placed on the surgical cart by the clamp 209, and the gooseneck tube 208 can be bent at any angle and fixed, thereby enhancing the practical effect, completing the flushing and suction operations. Furthermore, the double-tube syringe 1 is prevented from liquid leakage or seal cracking due to tilting or inversion, reducing the risk of contamination.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
