Description

Technical Field

[0001] This invention belongs to the field of medical device technology and relates to an integrated ophthalmic irrigation and ultrasonic emulsification machine. Background Technology

[0002] In ophthalmological clinical treatment, cataracts are a common eye disease with a high rate of blindness worldwide. Phacoemulsification cataract extraction has become the mainstream surgical procedure for treating cataracts due to its advantages such as minimal trauma and rapid postoperative recovery. The successful implementation of this procedure is highly dependent on an ophthalmic irrigation and phacoemulsification integrated machine. This type of equipment needs to simultaneously perform core functions such as irrigation fluid delivery, aspiration of intraocular impurities, and phacoemulsification and fragmentation of the cataract nucleus. Its performance and stability directly affect the safety of the surgery and the treatment effect.

[0003] In ophthalmic phacoemulsification surgery, to optimize the hydrodynamic stability within the anterior chamber, high-performance I / A handpiece needles are often designed with an irregular structure featuring continuous spiral grooves on the inner wall. While this spiral structure can induce stable laminar swirling flow, it also presents significant maintenance challenges: traditional ultrasonic cleaning or simple high-pressure fluid flushing tends to cause the fluid to flow along the central channel of least resistance, resulting in the "valley" of the spiral groove becoming a "cleaning dead zone" in terms of hydrodynamics. If the highly viscoelastic lens cortex adheres to and solidifies deep within the spiral groove during surgery, it can easily alter the flow field characteristics of subsequent procedures, and may even detach and enter the eye.

[0004] As a transparent and flexible silicone component, the infusion sleeve has micro-scratches or aging cracks on its surface that are extremely difficult to detect with the naked eye when static. In particular, the optical refraction properties of the transparent material can easily mask damage located on the back or lower side of the sleeve. Existing detection methods mostly rely on medical staff manually rotating and observing, which is not only inefficient but also prone to secondary contamination due to contact or missing "blind spots" due to a fixed viewing angle. Once a damaged sleeve is used in surgery, it can easily lead to unexpected leakage of the infusion fluid or mechanical damage to the corneal incision.

[0005] Therefore, there is an urgent need for an ophthalmic irrigation and ultrasonic emulsification machine that can mechanically scrape and clean spiral irregular cavities and perform dynamic full-circumference scanning of transparent sleeves. Summary of the Invention

[0006] In view of this, in order to solve the above problems, the present invention provides an integrated ophthalmic irrigation and ultrasonic emulsification machine.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an integrated ophthalmic irrigation and ultrasonic emulsification machine, comprising: Organism; An I / A handle is located on one side of the machine body. One end of the I / A handle is provided with an infusion interface and a suction interface, and the other end is fixedly connected to a needle. The needle is hollow and has a continuous spiral groove on its inner wall. An infusion sleeve is fitted on the outer wall of the needle. An infusion channel is formed between the infusion sleeve and the needle and is connected to the infusion interface. The filling / suction module is located on one side of the machine body. Its inlet end is used to connect to the solution bottle, and its outlet end is connected to the filling interface through the filling line II. The suction interface is connected to the filling / suction module through the suction line. A connecting box is located on one side of the machine body, and the top of the connecting box has an opening for the injection sleeve to be inserted; A U-shaped positioning bracket is fixedly installed on the top of the connection box to limit and fix the I / A handle when not in use; The cleaning mechanism, located inside the connecting box, includes a cleaning rod and a drive assembly. The top of the cleaning rod has a rubber block that is adapted to the spiral groove. When the I / A handle is pressed into the connecting box, the needle is sleeved on the outside of the cleaning rod, the rubber block is embedded in the spiral groove, and the cleaning rod is driven to rotate during the pressing process to scrape away residual impurities in the spiral groove.

[0008] As a further improvement to the above technical solution: The cleaning mechanism also includes a mounting bracket and a camera. The mounting bracket is fixedly sleeved on the bottom end of the cleaning rod, and the camera is mounted on the mounting bracket with its lens facing the outer wall of the filling sleeve. When the cleaning rod rotates, it drives the camera to move around the filling sleeve to perform all-round inspection of its outer wall.

[0009] The drive assembly includes a sleeve, a sliding rod, and a spring I. The sleeve is fixedly installed through the bottom of the connecting box. The sliding rod is slidably installed inside the sleeve, with its top end rotatably connected to the cleaning rod and its bottom end equipped with a contact switch. The spring I is sleeved outside the sliding rod and located between the cleaning rod and the bottom wall of the connecting box. When the I / A handle is pressed down, it drives the sliding rod to move down and compress the spring I until its bottom end triggers the contact switch. The contact switch is configured to control the infusion / aspiration module to infuse physiological saline into the connection box.

[0010] The cleaning mechanism also includes a sewage discharge component, which includes a sewage discharge pipe, a sliding pipe, and a spring II. The sewage discharge pipe is fixedly installed through the bottom of the connecting box. The sliding pipe is slidably installed inside the sewage discharge pipe and has multiple through holes on its outer wall. A sliding ring is slidably sleeved on the outside of the sleeve. The spring II is sleeved on the outside of the sleeve, with its two ends abutting against the bottom of the sliding ring and the bottom wall of the connecting box, respectively. The top end of the sliding pipe is fixedly connected to the bottom of the sliding ring. When the sliding rod is pressed down, it pushes the sliding ring down and compresses the spring II, thereby causing the sliding tube to move down, so that the inner wall of the sewage pipe blocks the through hole; When the pressure is released, the spring II pushes the sliding ring and sliding tube upward, and the through hole communicates with the inside of the connecting box to discharge sewage.

[0011] An extension strip is fixedly provided on the top of the U-shaped positioning frame. A locking block is connected to the bottom wall of the extension strip through an elastic strip. The locking block is used to tightly abut against the top of the I / A handle under its elastic action after the I / A handle is placed in the U-shaped positioning frame to achieve fixation.

[0012] The card block has an arc-shaped portion at one end near the I / A handle.

[0013] The top of the connecting box is also fixedly provided with a guide rod, and the outer wall of the injection sleeve is provided with a rectangular opening that matches the guide rod.

[0014] The machine body is equipped with a solution suspension rod for suspending solution bottles.

[0015] The back of the machine body is equipped with a folding hook for storing the power cord and a foot pedal controller hook for hanging the foot pedal controller.

[0016] The infusion / aspiration module has a detachable fluid cartridge, and the aspiration line is connected to the fluid cartridge.

[0017] The beneficial effects of this invention are as follows: This invention innovatively solves the cleaning problem of irregularly shaped cavities by setting a cleaning mechanism that precisely matches the spiral structure of the needle's inner wall. Utilizing the passive rotation of the cleaning rod when pressed down, it drives the rubber block to perform "contour scraping" within the spiral groove, physically forcibly removing stubborn adhering substances hidden in fluid cleaning blind spots such as the bottom of the spiral groove. This eliminates the risk of flow field variations caused by residue accumulation at the source, resulting in a more thorough cleaning. 2. This invention utilizes the kinetic energy of the rotating cleaning rod to synchronously drive the camera, achieving "circumferential dynamic scanning" of the stationary infusion sleeve. Compared to static observation by the human eye, the camera's circumferential motion captures the refraction changes of light on the sleeve surface from continuously changing angles, thereby accurately identifying minute scratches, cracks, or concentricity deformations that are difficult to detect from a conventional perspective. This ensures the physical integrity of the core surgical consumables and further guarantees surgical safety. 3. This invention establishes a linkage mechanism between cleaning and sewage discharge. The sewage discharge channel is closed at the moment of pressing down to scrape away impurities to form an immersion environment. At the moment of rebound and reset, the channel is opened to concentrate sewage discharge using gravity and elastic potential energy. This avoids sewage backflow or cross-contamination and eliminates the need for manual sewage treatment. The automated process reduces the operational burden and occupational exposure risk for medical staff.

[0024] Example 1

[0025] like Figures 1-9 As shown, an ophthalmic irrigation and phacoemulsification integrated machine includes a main body. The bottom of the main body is equipped with braked directional wheels 16 and non-brake omnidirectional wheels 17. The braked directional wheels 16 are installed on both sides of the front end of the bottom of the main body, and the non-brake omnidirectional wheels 17 are installed on both sides of the rear end of the bottom of the main body. Before surgery, when the device needs to be adjusted, medical staff only need to hold the push handle 12 on the side of the main body and gently push it. With the flexible steering of the non-brake omnidirectional wheels 17 and the guiding action of the braked directional wheels 16, the device can be easily moved to the target position next to the operating table. After moving it into place, pressing the brake pedal on the braked directional wheel 16 will cause the internal brake pads to fit tightly against the wheel, firmly locking the device and preventing displacement due to minor collisions during surgery, ensuring that the surgical operation is not disturbed. A power button 14 is located on the front of the device. Pressing the power button 14 will illuminate a green indicator light around it, indicating that the device is powered on. A ventilation window 13 is located next to the power button 14, equipped with a dust filter. This prevents external dust from entering the device and contaminating internal components, and also allows heat generated by the motherboard, motor, and other components during operation to dissipate promptly, preventing performance degradation or damage due to prolonged overheating and extending the device's lifespan. An adjustable solution suspension rod 1 is also located on the device. A control button 19 for the solution suspension rod 1 is located on the back of the device. Pressing the button unlocks the suspension rod, allowing it to move up and down. Medical personnel can adjust the solution suspension rod 1 to a suitable height according to the operating table height, solution bottle capacity, and the doctor's operating habits. After adjustment, releasing the button will automatically lock the suspension rod, preventing it from slipping due to the weight of the solution bottle during use. A hook with a smooth surface and anti-slip rubber sleeve is located at the top of the solution suspension rod 1, which stably suspends solution bottles containing saline or other surgical solutions, preventing the bottles from shaking or slipping.

[0026] The machine body is connected to a monitor 2 via a monitor bracket 11. One end of the monitor bracket 11 is securely connected to a mounting base on the top of the machine body with screws, and the other end is connected to the back of the monitor 2 via a universal joint. Medical staff can fold or rotate the bracket as needed to adjust the monitor 2 to any angle between 0 and 90 degrees, ensuring that doctors of different heights can clearly see the screen content during surgery without frequently adjusting their body posture. The monitor 2 displays various operating parameters of the device in real time, including perfusion pressure and aspiration negative pressure values. The parameter values ​​are presented in clear numerical and graphical form. When a parameter exceeds the preset safety range, the corresponding value will automatically turn red and flash, reminding medical staff to make timely adjustments. Multiple functional interfaces are located on one side of the machine body, including an ultrasonic emulsification interface 3, a dual electrocoagulation interface 4, a silicone oil injection and aspiration interface 5, a vitrectomy interface 6, a gas-liquid exchange interface 7, an illumination interface 8, and a pressurized perfusion interface 15. Each interface is clearly labeled for easy identification and connection of the corresponding instrument by medical staff. The interfaces use a snap-fit ​​design; when connecting an instrument, align the instrument plug with the interface and insert it. A slight "click" sound will be heard, indicating that the plug and interface are securely connected, preventing loosening due to vibration during use. The pressurized infusion interface 15 is used in scenarios requiring higher infusion pressure (such as when treating hard cataracts). After connecting an external pressurization device, the pressure can be finely adjusted via a knob on the device. The pressure adjustment range is precise and can be gradually adjusted according to the progress of the surgery, avoiding damage to intraocular tissues from sudden pressure increases. The back of the device has a USB interface 18, a cable folding hook 20, and a foot pedal controller hook 21. The USB interface 18 can be used to connect an external storage device to export the device's operating data during surgery, facilitating postoperative review or device maintenance; it can also be used to connect to a computer for software upgrades and updates. The folding hook 20 for electrical wires is equipped with elastic clips, allowing medical staff to wrap the power cords of the equipment and the connecting wires of various instruments around the hook in sequence and secure them with the clips. This prevents the wires from becoming tangled and saves space, while also preventing medical staff from tripping over the wires while moving around. The foot pedal controller hook 21 has an arc-shaped structure. When the foot pedal controller 9 is not in use, it can be hung on the hook, allowing the controller's wires to hang naturally and be stored on the folding hook 20. This prevents the controller from being placed on the ground and becoming contaminated or damaged, while also freeing up more operating space around the operating table.

[0027] A perfusion / aspiration module 22 is also located on one side of the device. The outer shell of the module is made of transparent medical plastic, allowing medical staff to directly observe the patency of the internal flow path. A fluid cartridge 10 is snapped into the perfusion / aspiration module 22. The cartridge has graduations for easy monitoring of the volume of collected lens debris and other impurities. When the impurities reach the graduations, medical staff simply grasp the protrusions on both sides of the cartridge and gently pull it outwards to remove the old cartridge. A new cartridge is then inserted into the slot within the module. The entire replacement process requires no tools, and the module has a temporary buffer channel, ensuring uninterrupted perfusion and aspiration procedures during cartridge replacement, thus guaranteeing continuous surgery. The inlet of the perfusion / aspiration module 22 is connected to a solution bottle suspended on a solution suspension rod 1 via a perfusion line I 23. Both ends of the perfusion line I 23 are equipped with sterile quick connectors containing sealing gaskets. During connection, aligning the connector with the outlet of the solution bottle and pressing it against the inlet of the module achieves a sealed connection, effectively preventing solution leakage or air ingress. The device also features an I / A handle 26 on one side. The handle is made of medical-grade ABS plastic with a non-slip texture, ensuring a secure grip even when medical staff's hands are wet with saline solution. One end of the I / A handle 26 has an infusion port 27 and a suction port 28, each with a different color marking (e.g., blue for infusion port 27 and red for suction port 28) for easy identification and connection of tubing. The connection between the ports and the infusion tubing 25 and suction tubing 24 also uses a quick-connect design with anti-accidental pull clips. To disassemble, press the clips first, then pull out the tubing to prevent accidental dislodgement during surgery. The infusion port 27 is connected to the drain end of the infusion / aspiration module 22 via the infusion line II 25, and the aspiration port 28 is connected to the fluid cartridge 10 via the aspiration line 24, forming a complete infusion and aspiration flow path: During surgery, the pump in the infusion / aspiration module 22 is activated, drawing the saline solution from the solution bottle into the module through the infusion line I 23. After filtration, it is then delivered to the infusion port 27 via the infusion line II 25 and enters the I / A handle 26. At the same time, lens debris, residual cortex, and other impurities generated during surgery are drawn into the aspiration port 28 through the infusion channel under negative pressure, and then collected in the fluid cartridge 10 via the aspiration line 24, realizing the simultaneous infusion of solution and aspiration of impurities, and maintaining a clear surgical field.

[0028] The other end of the I / A handle 26 is fixedly connected to a needle 29. The needle 29 is made of medical-grade titanium alloy, which has good biocompatibility and strength, will not irritate intraocular tissues, and is not easily deformed during use. The needle 29 has a hollow structure, and its internal channel is connected to the aspiration interface 28, ensuring that the saline solution can smoothly enter the needle 29 during surgery. The inner wall of the needle 29 has spiral grooves 291, which are evenly distributed along the axis of the needle 29. When the saline solution flows inside the needle 29, it forms a spiral flow along the spiral grooves 291. This not only enhances the flushing effect of the solution on the inner wall of the needle 29 and reduces the residue of impurities on the wall, but also reduces the noise generated by the flow of the solution, making the surgical environment quieter. This allows the aspiration interface 28 to quickly aspirate excess solution and impurities from the surgical area through the irrigation channel, maintaining stability. An infusion sleeve 30 is inserted into the outer wall of the needle 29. The infusion sleeve 30 is made of medical-grade transparent silicone, which has a certain degree of elasticity. The inner wall is coated with a medical lubricating coating, resulting in low resistance during insertion and preventing scratches on the outer wall of the needle 29. The length of the sleeve just covers the working part of the needle 29, protecting the needle 29 from impact damage when not in use and guiding the solution precisely to the surgical area during surgery, avoiding solution splashing. A uniform gap is left between the infusion sleeve 30 and the needle 29, forming an infusion channel. This infusion channel is connected to the infusion interface 27, allowing physiological saline to flow quickly to the surgical area through the infusion channel, maintaining anterior chamber stability.

[0029] A connection box 31 is also provided on one side of the device. The connection box 31 is made of medical-grade PP plastic and has a top-opening box structure. The inside of the box is smooth and easy to clean, and can be directly rinsed with saline during surgical intervals or after surgery. The size of the top opening of the connection box 31 is adapted to the outer diameter of the infusion sleeve 30, so that the infusion sleeve 30 can be inserted into the opening. A guide rod 36 is fixedly fixed through the top of the connection box 31. The guide rod 36 is a rectangular stainless steel rod with a smooth surface. Its axis is consistent with the height direction of the connection box 31, which can provide guidance for the placement of the I / A handle 26. The outer wall of the infusion sleeve 30 has a rectangular opening 301 that cooperates with the guide rod 36 to ensure that the infusion sleeve 30 is accurately inserted into the connection box 31. A U-shaped positioning frame 32 is fixedly connected to the top of the guide rod 36. The U-shaped positioning frame 32 is made of elastic metal material and has a certain deformation capacity. Its opening faces the I / A handle 26. An extension strip 321 is fixedly connected to the top of the U-shaped positioning frame 32. The extension strip 321 extends outward radially along the U-shaped positioning frame 32, with a moderate length that will not affect the doctor's operation. An elastic strip 322 is fixedly connected to the bottom wall of the extension strip 321. The elastic strip 322 is made of medical-grade silicone, which has good elasticity and toughness, can deform within a certain range, and will not age due to long-term use. A locking block 323 is fixedly connected to the top of the elastic strip 322. When the I / A handle 26 is placed inside the U-shaped positioning frame 32, the I / A handle 26 will move outward against the locking block 323, causing the elastic strip 322 to deform and firmly fix the handle inside the positioning frame, preventing the handle from wobbling or slipping when not in use. The end of the locking block 323 near the I / A handle 26 has an arc-shaped part 324. The arc-shaped part 324 is a smooth arc transition structure without sharp edges. When the I / A handle 26 is placed into the U-shaped positioning frame 32, the arc-shaped part 324 can guide the outer wall of the handle to slide smoothly into the gap between the locking block 323 and the positioning frame, avoiding the locking block 323 from directly rigidly contacting the outer wall of the handle and causing it to jam. This makes the placement and removal of the handle smoother. After the I / A handle 26 is inserted into place, the locking block 323 can be reset under the action of the elastic bar 322 and locked on the top of the I / A handle 26, limiting the I / A handle 26.

[0030] The connecting box 31 is equipped with a cleaning mechanism 33, which is used to thoroughly clean the inner wall of the needle 29 and the spiral groove 291 during surgical intervals or after surgery, preventing residual impurities from causing contamination or affecting the irrigation and aspiration effect in the next operation. The cleaning mechanism 33 also includes a drainage component to promptly discharge wastewater generated during the cleaning process from the connecting box 31, keeping the box clean. The cleaning mechanism 33 includes a sleeve 331, which is made of medical-grade stainless steel, possessing excellent corrosion resistance and will not rust even after prolonged contact with saline. The sleeve 331 is a cylindrical tubular structure that runs through and is fixed to the bottom of the connecting box 31, with a welded seal between the sleeve and the box to prevent saline leakage from the connection point. The axis of the sleeve 331 is aligned with the height direction of the connecting box 31, and its hollow interior with a smooth inner wall provides a stable channel for the movement of the sliding rod 332. A sliding rod 332 is slidably mounted inside the cannula 331. The sliding rod 332 is also made of stainless steel, and its outer wall fits tightly against the inner wall of the cannula 331 with minimal gaps. This ensures smooth up-and-down sliding of the sliding rod 332 while preventing saline solution from seeping into the cannula 331 through the gaps. A cleaning rod 338 is rotatably connected to the top of the sliding rod 332 via a precision bearing. The bearing is a medical-grade sealed bearing, preventing saline solution from entering the bearing and affecting rotational performance, while also providing some resistance so it will not rotate without external force. The cleaning rod 338 can rotate flexibly around its own axis. Its material is the same as the needle 29, a medical-grade titanium alloy, which is high-strength and not easily deformed. A rubber block 339 is fixedly connected to the outer wall of the top of the cleaning rod 338. This rubber block 339 can be made of antibacterial silicone (with added nano-silver). The rubber block 339 is made of medical-grade soft silicone with moderate hardness, providing sufficient elasticity to fit tightly against the spiral groove 291 without being too hard and scratching the inner wall of the needle 29. The shape of the rubber block 339 is perfectly matched with the spiral groove 291 on the inner wall of the needle 29. When the cleaning rod 338 is inserted into the needle 29, the rubber block 339 will be precisely embedded in the spiral groove 291. As the cleaning rod 338 moves up and down and rotates, the rubber block 339 can completely scrape away the crystal debris, cortex and other impurities remaining in the spiral groove 291. The scraped impurities will be pumped into the fluid cartridge 10 along with the saline solution. At the same time, as the needle 29 descends, the cleaning rod 338 can be driven to rotate through the cooperation of the spiral groove 291 and the rubber block 339.

[0031] A mounting bracket 34 is fixedly fitted onto the bottom outer wall of the cleaning rod 338. The mounting bracket 34 is made of lightweight aluminum alloy, ensuring sufficient strength without increasing the overall weight of the cleaning rod 338. The mounting bracket 34 has a stable frame structure, providing reliable support for the camera 35. Cameras 35 are fixedly connected to both sides of the top of the mounting bracket 34 with screws. The cameras 35 are miniature high-definition cameras (with optional LED supplemental lighting), small in size and not affecting the movement and rotation of the cleaning rod 338. The lens of the camera 35 faces the outer wall of the infusion sleeve 30, and the lens surface is coated with an anti-fog coating, which quickly dissipates even if fog is generated upon contact with saline solution, ensuring a clear image. The camera 35 uses a wireless transmission module to send signals to the display 2, and the captured image is transmitted to the display in real time, allowing medical personnel to clearly observe the condition of the outer wall of the infusion sleeve 30. When the cleaning rod 338 is inserted into the needle 29, the rubber block 339 is embedded in the spiral groove 291. As the cleaning rod 338 moves axially downward, the spiral groove 291 exerts a circumferential force on the rubber block 339, causing the cleaning rod 338 to slowly rotate around its own axis. The rotation of the cleaning rod 338 causes the mounting bracket 34 at the bottom to rotate synchronously. The mounting bracket 34 then causes the two cameras 35 to move in a circular motion around the axis of the infusion sleeve 30, achieving 360-degree inspection of the outer wall of the infusion sleeve 30 without blind spots. This ensures that minor scratches, cracks, and other damage to the outer wall of the infusion sleeve 30 can be detected in a timely manner, avoiding the use of damaged sleeves for surgery and reducing surgical risks.

[0032] A plug 336 is fixedly connected to the bottom of the cannula 331. The plug 336 is made of medical-grade rubber, which has good sealing and elasticity, and can tightly seal the bottom opening of the cannula 331 to prevent saline from leaking into the machine body from the bottom of the cannula 331. A contact switch 337 is embedded in the top of the plug 336. The contact switch 337 is a waterproof microswitch that can work stably in humid environments. It is electrically connected to the infusion / aspiration module 22 through wires to form a control circuit. The bottom of the sliding rod 332 is a flat end face. When the sliding rod 332 moves down to a certain position, the bottom end face will contact the button of the contact switch 337 and press the button, triggering the contact switch 337 to control the flow of saline and use saline for temporary humidification. A spring I 333 is sleeved on the outer wall of the sliding rod 332. The spring I 333 is a medical-grade stainless steel spring with good elasticity and corrosion resistance, and will not rust or lose elasticity due to long-term contact with saline. Spring I 333 is located between the cleaning rod 338 and the bottom wall of the connecting box 31. When the sliding rod 332 is not pressed by an external force, spring I 333 is in a naturally extended state, supporting the cleaning rod 338 in a higher position, which facilitates the placement of the I / A handle 26. When it is necessary to fix the needle 29, the medical staff presses the sliding rod 332 downward, and spring I 333 is compressed and stores elastic potential energy. When the latch 323 is opened, spring I 333 will return to its natural state under the action of elastic potential energy, pushing the sliding rod 332 upward to return to the initial position, preparing for the next cleaning. When the sliding rod 332 moves downward and presses the contact switch 337, the contact switch 337 sends an electrical signal to the infusion / aspiration module 22. After receiving the signal, the module immediately starts the infusion function, delivering physiological saline through the infusion line I 23, the infusion / aspiration module 22, the infusion line II 25, and the infusion interface 27 to the needle 29. After the physiological saline flows out from the tip of the needle 29, it flows into the connecting box 31, gradually accumulating and submerging the needle 29 and the infusion sleeve 30. At this time, the physiological saline can not only soak and clean the needle and sleeve, but also carry away the impurities scraped off by the rubber block 339, further improving the cleaning effect.

[0033] The sewage discharge assembly includes a sewage pipe 37, made of medical-grade PVC, which has good corrosion resistance and flexibility. It is fixed to the bottom of the connecting box 31 and sealed with sealant to prevent leakage. The sewage pipe 37 is connected to the interior of the connecting box 31, serving as the channel for sewage discharge. A disposable sterile hose can be connected to the bottom of the sewage pipe 37, with the other end of the hose placed in a sewage collection bucket to prevent sewage from dripping directly onto the ground. A sliding tube 38, also made of medical-grade PVC, is slidably installed inside the sewage pipe 37. Its outer wall fits tightly against the inner wall of the sewage pipe 37, allowing it to slide smoothly up and down along the axis of the sewage pipe 37 without wobbling. Multiple through holes 381 are formed on the outer wall of the sliding tube 38, evenly distributed circumferentially and axially. The holes are of appropriate size, ensuring smooth sewage passage while preventing larger impurities from clogging them. When the through hole 381 is connected to the inside of the connecting box 31, the sewage in the connecting box 31 will enter the sliding tube 38 through the through hole 381 under the action of gravity, and then flow into the drain pipe 37 from the bottom of the sliding tube 38, and finally be discharged into the collection bucket through the hose. When the through hole 381 is blocked by the inner wall of the drain pipe 37, the sewage cannot enter the sliding tube 38, thus closing the sewage discharge channel. The top outer wall of the sleeve 331 is slidably fitted with a sliding ring 334. The sliding ring 334 is made of medical-grade plastic with a smooth inner wall, which fits tightly against the outer wall of the sleeve 331 and can slide flexibly up and down along the axis of the sleeve 331 without jamming. The outer wall of the sleeve 331 is fitted with a spring II 335. The spring II 335 is made of the same material as the spring I 333, which is medical-grade stainless steel spring, with good elasticity and corrosion resistance. Both ends of spring II 335 abut against the bottom of sliding ring 334 and the bottom wall of connecting box 31 respectively via spring seats. The spring seats are made of medical-grade plastic, which can evenly transmit the spring force to sliding ring 334 and the bottom wall of connecting box 31, avoiding excessive local pressure that could damage the components. When sliding ring 334 is not subjected to external force, spring II 335 is in a naturally extended state, supporting sliding ring 334 in a higher position; when sliding ring 334 is subjected to downward pressure, spring II 335 is compressed; when the pressure is removed, spring II 335 will push sliding ring 334 upward to return to its initial position. The top of sliding tube 38 is fixedly connected to the bottom of sliding ring 334 with glue, ensuring a firm connection that will not detach due to soaking in sewage.When the sliding rod 332 is subjected to downward pressure, its bottom will contact the top of the sliding ring 334 and push the sliding ring 334 to move downward. The sliding ring 334 drives the sliding tube 38 to move downward along the drain pipe 37. At this time, the inner wall of the drain pipe 37 will gradually block the through hole 381 on the sliding tube 38 until the through hole 381 is completely blocked, closing the drain channel and preventing saline solution from leaking during the cleaning process. When the pressure on the sliding rod 332 is released, the spring II 335 will push the sliding ring 334 to move upward. The sliding ring 334 drives the sliding tube 38 to move upward, and the through hole 381 gradually connects with the inside of the connecting box 31, so that the sewage can be discharged through the through hole 381.

[0034] In actual use, the ophthalmic irrigation and phacoemulsification integrated machine is first activated by pressing the power button 14 on the front of the machine. The green indicator light illuminates, signifying that the device is powered on and started. Simultaneously, the display 2 will turn on, entering the parameter setting interface. Medical staff set the safe ranges for parameters such as irrigation pressure and aspiration negative pressure on the display according to the surgical needs. Then, the height of the solution suspension rod 1 is adjusted using the solution suspension rod control button 19, suspending the solution bottle containing physiological saline on the hook at the top of the suspension rod, ensuring that the outlet of the solution bottle is higher than the irrigation / aspiration module 22, utilizing gravity to assist solution flow. Next, the outlet of the solution bottle is connected to the inlet of the irrigation / aspiration module 22 via the irrigation line I 23. During connection, ensure the quick connector is pressed firmly; after hearing a "click," gently pull the line to confirm a secure connection. Depending on the surgical needs, the phacoemulsification handpiece, dual electrocoagulation instruments, etc., are connected to the corresponding interfaces on one side of the machine. After each connection is completed, the tightness of the connection must be checked. Remove the foot pedal controller 9 from the foot pedal controller hook 21 and place it in a position that the doctor can easily reach during surgery. At the same time, wrap the power cord of the device and the connecting wires of each instrument around the wire folding hook 20 and fix them with elastic clips to avoid tangling of the wires.

[0035] During the procedure, the surgeon holds the I / A handle 26, aligns the needle 29 and the infusion sleeve 30 with the surgical area, and activates the infusion / aspiration module 22 by stepping on the foot pedal controller 9. The infusion / aspiration module 22 draws physiological saline from the solution bottle through infusion line I 23, delivers it through infusion line II 25 to the infusion interface 27, then between the needle 29 and the infusion sleeve 30, and flows out from the tip of the needle through the infusion channel to the surgical area, providing continuous solution infusion for the surgery. Simultaneously, lens debris, residual cortex, and other impurities generated during the procedure are drawn into the aspiration interface 28 through the needle 29 under negative pressure, and collected in the fluid cartridge 10 via the aspiration line 24. The surgeon can monitor parameters such as infusion pressure and aspiration negative pressure in real time on the display 2. If any abnormalities are detected, adjustments are made promptly using the foot pedal controller or the adjustment buttons on the display to ensure the safety of the procedure. When the impurities in the fluid cartridge 10 reach the scale line, medical staff can directly remove the old cartridge and insert the new cartridge without interrupting the surgery. The temporary buffer channel in the module will ensure that the perfusion and aspiration process is continuous and does not affect the progress of the surgery.

[0036] When cleaning the needle 29 and infusion sleeve 30 is required during or after surgery, the doctor inserts the infusion sleeve 30 of the I / A handle 26 from the side, aligning it with the opening at the top of the connector box 31. Guided by the guide rod 36, the sleeve is slowly inserted while the I / A handle 26 is placed inside the U-shaped positioning frame 32. At this time, the locking block 323 on the U-shaped positioning frame 32 will be in close contact with the outer wall of the handle under the action of the elastic strip 322, preventing shaking. The medical staff presses down on the I / A handle 26, and the cleaning rod 338 is inserted into the needle 29. The rubber block 339 at the top of the cleaning rod 338 is embedded in the spiral groove 291 on the inner wall of the needle 29. With the continuous pressing of the sliding rod 332, the cleaning rod 338 begins to rotate slowly under the action of the spiral groove 291, causing the camera 35 on the bottom mounting bracket 34 to rotate around the outer wall of the infusion sleeve 30. The image captured by the camera 35 is transmitted to the monitor 2 in real time, and the medical staff can observe whether there is any damage to the outer wall of the infusion sleeve 30 through the monitor. When the sliding rod 332 moves downward to a certain position, its bottom presses the contact switch 337. The contact switch 337 sends a signal to the infusion / aspiration module 22, and the module starts the infusion and aspiration functions, delivering physiological saline to the needle 29. The physiological saline flows out from the needle and into the connecting box 31, gradually submerging the needle 29 and the infusion sleeve 30. During the rotation of the rubber block 339, the residual impurities in the spiral groove 291 are completely scraped off. The impurities flow into the fluid cartridge 10 along with the physiological saline. After cleaning, the infusion work is carried out, so that the physiological saline enters the connecting box 31 until the needle 29 and the infusion sleeve 30 are submerged. During the downward movement of the cleaning rod 338, the sliding ring 334 moves downward through the spring I 333, causing the sliding tube 38 to move downward, and the drain pipe 37 seals the through hole 381.

[0037] After cleaning, medical staff open the locking block 323. Spring I 333 pushes the sliding rod 332 upward, and the cleaning rod 338 pushes the needle 29 upward. At the same time, spring II 335 pushes the sliding ring 334 upward, which in turn moves the sliding tube 38 upward. The through hole 381 on the sliding tube 38 connects to the inside of the connection box 31. Wastewater in the connection box 31 enters the sliding tube 38 through the through hole 381, and then flows into the collection bucket through the drain pipe 37 and the hose. After wastewater discharge, the I / A handle 26 is removed from the U-shaped positioning frame 32. If it is still needed later, the surgery can continue. If the surgery is over, disconnect each instrument from the interface in sequence, hang the foot pedal controller 9 back on the foot pedal controller hook 21, tidy up the wires, and finally press the power button 14 to turn off the equipment. Clean and disinfect the surface of the equipment, and wait for the next use.
