Description

Technical Field

[0001] This invention belongs to the field of medical device technology and relates to an intelligent ophthalmic phacoemulsification device. Background Technology

[0002] In ophthalmological clinical treatment, phacoemulsification surgery is often used to treat eye diseases such as cataracts. During the procedure, a continuous and stable supply of irrigation fluid is crucial for maintaining intraocular pressure (IOP) and the surgical field of vision.

[0003] Currently, to address the issue of interrupted intraoperative fluid replacement, clinicians often employ a dual-bottle series connection or a Y-shaped tubing system with a pre-attached backup fluid bottle. However, existing technologies, while solving the "continuous fluid supply" problem, often overlook the hidden risk of "sterile protection and physical condition maintenance of backup components during standby."

[0004] In existing dual-pathway infusion systems, achieving "instant switching" of the standby needle typically requires removing the needle sheath beforehand and suspending it in the air. This exposes the needle tip to the laminar airflow of the operating room for an extended period, making it highly susceptible to attracting airborne dust or crystallizing medication that could clog the needle puncture site, increasing the potential risk of postoperative endophthalmitis. If the sheath is retained for protection, fully automated mechanical switching cannot be achieved the instant the medication runs out. Furthermore, to ensure smooth switching, medical staff usually need to open the dust cap (easy-open cap) of the standby infusion bottle before the procedure, causing the self-sealing rubber stopper of the infusion bottle to prematurely lose its sterile barrier protection before puncture, resulting in prolonged exposure to the external environment.

[0005] Therefore, designing a device that can keep the spare needle and spare bottle opening in a completely sealed and sterile state, and can achieve rapid and automatic puncture switching without manual intervention to remove the cap / open the lid, is a technical problem that urgently needs to be solved in current ophthalmic surgical fluid supply systems. Summary of the Invention

[0006] In view of this, in order to solve the above problems, the present invention provides an intelligent ophthalmic phacoemulsification device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an intelligent ophthalmic phacoemulsification device, comprising:

[0008] The machine body is provided with a solution suspension rod, the solution suspension rod includes a lifting rod, and a fixing plate is fixedly sleeved on the lifting rod, the fixing plate is used to support two infusion bottles;

[0009] An infusion tube is located on one side of the lifting rod. The infusion tube is Y-shaped and has two puncture needles at its top end. The puncture needles are used to insert into the infusion bottle.

[0010] A replacement mechanism, sleeved on the lifting rod, is used to automatically replace one infusion bottle by inserting another puncture needle into the unused infusion bottle after one of the infusion bottles has been used up.

[0011] The handle has a needle at one end and is connected to the machine body via a connecting cable at the other end. The handle has an infusion port and a suction port. The infusion port is connected to the pressurized infusion interface of the machine body via a pipe. Liquid is delivered to the surgical area through the puncture needle, infusion tube, pressurized infusion interface and infusion port.

[0012] As a further improvement to the above technical solution:

[0013] A U-shaped limiting opening is provided on one side of the fixing plate, which is adapted to the mouth of the infusion bottle; a connector is fixedly provided at the top of the lifting rod, and swing heads are provided on both sides of the connector. The swing heads abut against the groove at the bottom of the infusion bottle under their own weight to limit the movement and prevent the infusion bottle from shaking.

[0014] The replacement mechanism includes a replacement frame, which is V-shaped and sleeved on the outer wall of the lifting rod. Both ends of the replacement frame are provided with second limiting openings, and the puncture needle is interference-fitted into the second limiting openings.

[0015] The top of the fixed plate is equipped with a motor, and the output end of the motor is connected to a second gear. The top of the switching frame is equipped with a first gear, which meshes with the second gear. The motor drives the switching frame to rotate so that the puncture needle is accurately aligned with the infusion bottle.

[0016] It also includes a sliding ring, which is slidably sleeved on the outer wall of the lifting rod, and a rotating ring is rotatably sleeved on the outer wall of the sliding ring. The switching frame and the first gear are both fixedly sleeved on the sliding ring.

[0017] The outer wall of the sliding ring is fixedly fitted with a lifting plate, and the first gear is located inside the lifting plate;

[0018] The top of the fixed plate is equipped with an electric push rod, the output end of which is connected to the lifting plate. The electric push rod drives the changing frame to rise and fall to achieve smooth insertion and removal of the puncture needle.

[0019] A sleeve rod is rotatably provided through the top of the fixed plate, and a connecting shaft is slidably provided inside the sleeve rod. The second gear is fixedly sleeved on the bottom end of the connecting shaft. The connecting shaft rises and falls with the changing frame to maintain gear meshing and ensure continuous transmission.

[0020] The switching frame has two extension blocks on one side. The extension blocks are L-shaped and correspond to the infusion bottle. The outer end of the extension block cooperates with the easy-open cap of the infusion bottle mouth. The easy-open cap is automatically opened when the puncture needle is inserted or removed, reducing human contact contamination.

[0021] The fixing plate has a connecting seat on one side, and a protective cylinder is threaded through the top of the connecting seat. A rubber plug is embedded in the bottom opening of the protective cylinder. Unused puncture needles are inserted into the rubber plug to be protected by the protective cylinder, so as to avoid the needle tip being exposed, contaminated or punctured.

[0022] The machine body is equipped with an electric push rod, and the bottom end of the lifting rod passes through the top of the machine body and is fixedly connected to the output end of the electric push rod.

[0023] A solution suspension rod control button is embedded on one side of the machine body. The solution suspension rod control button controls the lifting rod to raise and lower to adjust the height of the infusion bottle.

[0024] The device is equipped with a monitor connected to a monitor bracket. One side of the device is provided with an ultrasonic emulsification interface, a dual electrocoagulation interface, a silicone oil injection and aspiration interface, a glass cutting interface, a gas-liquid exchange interface, a lighting interface, a fluid cartridge, and a power button. The back of the device is provided with a USB interface. The fluid cartridge is used to adjust the liquid flow parameters.

[0025] The back of the machine body is equipped with a folding hook for the power cord and a foot pedal controller hook. The folding hook for the power cord is used to store the power cord to avoid tangling, and the foot pedal controller hook is used to store the foot pedal controller that is connected to the machine body by a wire, thus saving operating space.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. This invention resolves the contradiction between "sterile standby" and "automatic switching." By incorporating a protective sleeve with an embedded rubber stopper, the puncture needle in standby mode can be physically isolated by inserting it into the rubber stopper. This not only avoids the risk of particulate contamination and liquid crystallization caused by prolonged exposure of the needle tip to air, but also utilizes the self-closing property of the rubber stopper to achieve "bare needle protection" without the need for a needle cap. When switching is required, the mechanical structure directly pulls the needle out of the protective stopper and inserts it into the infusion bottle, eliminating the need for manual removal of the needle cap, thus truly achieving fully automated, closed-loop sterile switching.

[0028] 2. This invention achieves "on-site opening" of the infusion bottle by using the L-shaped extension block on the side of the switching frame in conjunction with the easy-open cap of the infusion bottle. Unlike traditional surgeries that require opening a spare cap in advance, this device allows the infusion bottle to remain completely sealed with the easy-open cap closed until puncture. The cap is automatically opened only at the moment the puncture needle is about to be inserted, using the pull-out / displacement action of the robotic arm. This design minimizes the time the rubber stopper of the infusion bottle is exposed to air, reducing the probability of exogenous contamination to the greatest extent possible.

[0029] 3. The intelligent ophthalmic phacoemulsification device disclosed in this invention operates smoothly when the electric push rod drives the changing frame to rise and fall, making the insertion and removal of the puncture needle slow and controllable. The first gear and the second gear mesh tightly, and there is no slippage in the transmission process. The rotation angle of the changing frame is precise, ensuring that the puncture needle can be accurately aligned with the mouth of the infusion bottle. With the help of the U-shaped limiting port to fix the infusion bottle, the insertion position deviation can be controlled within a very small range, avoiding needle bending or bottle damage caused by misalignment.

[0030] 4. The intelligent ophthalmic phacoemulsification device disclosed in this invention only requires two infusion bottles to be inserted into the U-shaped limiting port before the operation, and they are naturally fixed by the swing head. There is no need for complicated positioning adjustments. During the operation, medical staff do not need to pay attention to the remaining amount of the infusion bottles and manually replace them. This reduces the auxiliary operations during the operation, allowing medical staff to focus on the core steps of the operation. Especially in multiple consecutive operations, it can significantly reduce the physical exertion and mental stress of medical staff and improve work efficiency.

[0031] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0046] Example 1

[0047] like Figures 1-9 As shown, an intelligent ophthalmic phacoemulsification device 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 located at the two front corners of the main body. The wheels are made of wear-resistant rubber with fine grooves on the surface, resulting in low noise during operation, suitable for a quiet surgical environment. The brake pedals of the braked directional wheels 16 have rounded edges to prevent foot discomfort when pressed, and they will not slip even on smooth tile floors when locked. The non-brake omnidirectional wheels 17 are located at the two rear corners, with miniature bearings embedded in their rotating shafts, ensuring smooth rotation without jamming. Combined with the push handle 12 on the back of the main body, medical staff can easily push the device to adjust its position. The push handle 12 is covered with anti-slip rubber with diagonal grooves, preventing slippage during grip, making it particularly suitable for quickly moving the device to the operating table before surgery, even with hands wet with disinfectant.

[0048] The front of the machine has multiple functional interfaces, arranged from left to right as follows: ultrasonic emulsification interface 3, dual electrocoagulation interface 4, silicone oil injection and aspiration interface 5, glass cutting interface 6, gas-liquid exchange interface 7, and lighting interface 8. The interface areas are recessed to prevent liquid from splashing into the interface. Each interface has corresponding text markings on its edge, which can be clearly seen even in low light, making it easy to quickly distinguish and connect. The ultrasonic emulsification interface 3 connects to the main circuit of the handle 22. Its plug has a spring-loaded latch that automatically locks after insertion. To remove it, the latch button must be pressed to prevent accidental dislodgement during surgery. The dual electrocoagulation interface 4 connects to bipolar electrocoagulation instruments. Its inner wall has conductive copper plates to ensure stable current transmission, suitable for delicate hemostasis operations. The silicone oil injection / aspiration interface 5 is specifically designed for silicone oil injection and aspiration devices. Its slightly larger diameter ensures a tight seal after connection, preventing silicone oil leakage. The vitrectomy interface 6 connects to the vitrectomy handle and has a rubber sealing ring at the end, maintaining a good seal even after repeated insertions and removals. The gas-liquid exchange interface 7 handles intraocular gas-liquid replacement during surgery. The illumination interface 8 connects to the light source circuit of the surgical microscope. The illumination function provides two light sources, both equipped with adjustable attenuators. It can provide an output of over 25 lumens. The light source located at bulb 1 can use one of seven color filters (amber, orange, yellow, dark green, light green, pale green, and white). These two interfaces are positioned slightly lower for easy connection to circuits near the surgical microscope, preventing tubing from becoming tangled in the surgical area. These interfaces are all designed to prevent incorrect insertion, thus avoiding connection errors. The foot controller 9 can be used for wired or wireless communication. When using the XR1300 for the first time, a wired connection must be used to establish communication between the foot controller and the XR1300. For wired communication, connect the spare cable of the foot controller from the back of the foot controller to the FOOTCONTROL on the back of the XR1300. To use the foot controller in wireless mode, ensure the foot controller's battery is charged and the device is powered on. Then, press and hold any button on the foot controller and wait for several seconds to establish communication. When the foot controller is wirelessly communicating with the main device, the green ready indicator light (indicated by the following symbol) will remain lit. If the main device does not detect a wireless connection from the foot controller during operation, wireless operation will be disabled. The foot controller icon will appear grayed out in the main settings and operating screen.

[0049] Monitor 2 is mounted on the top of the machine via monitor bracket 11. The metal arm of monitor bracket 11 has damping washers, allowing it to fold forward and backward and rotate up and down without suddenly dropping during angle adjustment. It can stop at any position, ensuring that the doctor can adjust monitor 2 to eye level when standing and rotate it down to chest height when sitting, so that parameters can be clearly seen without bending down or turning to the side. Monitor 2's screen is covered with an anti-blue light film to reduce eye strain during prolonged viewing. A light sensor on the bottom bezel of the screen automatically adjusts the screen brightness according to the brightness of the operating room, avoiding glare from strong light or poor visibility in dim light. The front of the machine has a fluid cartridge 10 with a transparent protective cover. The cover has grooves on the edge, which can be easily lifted by pressing the grooves with your fingers. Inside, you can see the adjustment knob. The knob has a non-slip surface, providing a smooth feel when rotating. Each rotation shows a precise change in parameters such as flow rate and pressure on the screen, allowing the doctor to quickly retrieve preset surgical parameters. Next to the fluid cartridge 10 is the power button 14. When pressed, the device starts up, and the ring light around the button lights up. It is orange when in standby mode and turns green when running, which intuitively displays the device status.

[0050] The back of the device features a pressurized infusion port 15 and a USB port 18. The pressurized infusion port 15 is connected to the infusion port 24 of the handle 22 via a pipe, providing stable infusion pressure to the surgical area. It is connected to a transparent flexible tube with a spiral connector at the end. When aligning with the infusion port 24 of the handle 22, it can be tightened by turning it two turns. The silicone sealing ring at the connector will expand with the tightening force to ensure that the infusion fluid does not leak. The USB port 18 can be used to insert a USB flash drive for exporting surgical records or updating the device program. A "Data Transfer" label is affixed above the port to prevent accidental insertion. It has a push-pull dust cover, which can be pushed up when not in use to prevent dust and liquid from entering. When inserting the USB flash drive, you can feel slight resistance, and after it is fully inserted, there will be a slight click, indicating a successful connection. The back is also equipped with a folding hook 20 for the power cord and a foot pedal controller hook 21. The folding hook 20 is made of elastic plastic and can be bent into an arc to wrap around the connecting cable 25. The end of the hook has a small protrusion to prevent the power cord from slipping. It can also wrap and store excess connecting cable 25 to prevent the cable from hanging on the ground and causing tripping. The foot pedal controller hook 21 is positioned slightly lower to make it easy to hang up unused foot pedal controllers 9. The rubber pad on the hook can prevent the surface of the controller from being scratched and save floor space.

[0051] The basic structure of the implantable ophthalmic surgical system (GenesisSystemXR1300) software is mainly divided into preoperative, intraoperative, postoperative, and system settings.

[0052] Before surgery: The ophthalmic surgery system software provides users with user login, surgery type selection, and surgical configuration file selection. Users can configure these settings themselves. Users can create, delete, and modify user information on the login interface. After successful login, users are offered surgery type selection: anterior segment, posterior segment, and combined. Different surgery types provide corresponding surgical environments; for example, selecting anterior segment surgery provides a phacoemulsification surgical environment. After selecting a surgery type, users can choose pre-configured surgical parameters to enter the surgical system (hereinafter referred to as the programming system, which will be described in detail below), or they can choose the default surgical parameters of the ophthalmic surgery system to enter the surgery.

[0053] During surgery: Before officially starting the surgery, the user needs to perform a loading test on the consumable kits, handpieces, etc., required for the operation. This loading test is a built-in self-check function of the system. Only after the consumable kits, handpieces, etc., that need to be tested pass the self-check can the operation begin; otherwise, restrictions will be imposed. Once in surgery, the user can adjust parameters via the touchscreen and adjust the real-time output of each module via the foot pedal controller to provide the necessary hardware environment for the surgery.

[0054] Post-operative: After the surgery, the user can select "End" on the touchscreen to enter the ending interface. This interface provides a surgical summary, statistics on the packaged supplies, the start time of each surgical step, and output information for some steps, such as the start time and average cutting speed for vitrectomy. The post-operative statistics aim to provide feedback on the progress of the surgery, allowing users to analyze patient pathology, disease severity, and recovery period.

[0055] System Settings: The ophthalmic surgery system provides users with a programming system for custom surgical parameters, as well as rich system settings, foot pedal settings, etc.

[0056] The solution suspension rod 1 is installed on the top of the machine body. The output end of the electric actuator inside the machine body is connected to the lifting rod 101 for suspending the infusion bottle. The solution suspension rod control button 19 is embedded in the side of the machine body. Pressing it once raises the lifting rod 101, and pressing it again lowers it. The pressing stroke is moderate, and a slight "beep" sound is heard when pressing, indicating that the command has been received. The raising and lowering process is smooth. Releasing it stops the raising and lowering. The speed of raising and lowering the lifting rod 101 is uniform and will not suddenly accelerate, causing the infusion bottle to shake. There is no obvious shaking. The surface of the lifting rod 101 is chrome-plated, smooth and corrosion-resistant. The parts that come into contact with the machine body during raising and lowering have nylon bushings to reduce friction noise. A fixing plate 104 is fixedly sleeved on the lifting rod 101. The fixing plate 104 has U-shaped limiting ports 109 at both ends, into which the mouth of the infusion bottle can be inserted. A silicone pad is attached to the inside of the limiting port. The silicone pad is made of medical grade material and has a certain degree of elasticity. It can fix the infusion bottle without abrading the bottle body. After the infusion bottle is inserted, it will be gently wrapped and will not shift even if the equipment moves slightly. The distance between the two U-shaped limiting ports 109 is large enough to prevent the two infusion bottles from squeezing each other. A swing head 103 is installed on each side of the connector 102 at the top of the lifting rod 101. The swing head 103 is a solid structure and heavy, which can rotate freely under external force. When it hangs down naturally, the force is just enough to press down on the infusion bottle and will not cause the bottle to deform due to excessive pressure. The end is covered with a soft rubber sleeve, which is removable and can be replaced after wear. The surface of the sleeve has small bumps to increase the friction with the infusion bottle and fits perfectly into the groove at the bottom of the infusion bottle. Together with the U-shaped limiting port 109, it forms a double fixation to prevent the infusion bottle from shaking or falling off.

[0057] The infusion tube 107 on one side of the lifting rod 101 is Y-shaped (both branches are equipped with one-way valves (or electromagnetic check valves) to prevent backflow and air intake). The tube body has a certain degree of toughness and will not deform when slightly pulled, ensuring smooth fluid delivery. The inner wall of the branch is smooth, preventing vortex formation and reducing air bubbles. Two puncture needles 111 are installed at the top, which can be inserted into two infusion bottles respectively. The drain port of the infusion tube 107 is connected to the pressure infusion interface 15 of the machine body through a dedicated pipe. After the fluid enters the Y-shaped infusion tube 107 from the infusion bottle through the puncture needles 111, it flows into the connecting pipe through the drain port, and then enters the infusion system inside the machine body through the pressure infusion interface 15. Finally, it is delivered to the infusion port 24 of the handle 22 through the pipe connected to the pressure infusion interface 15, providing continuous infusion fluid to the surgical area and maintaining stable intraocular pressure. The replacement mechanism on the lifting rod 101 is used to automatically replace the infusion bottle. The replacement mechanism includes a replacement frame 106 sleeved on the outer wall of the lifting rod 101. The replacement frame 106 is V-shaped and symmetrical in structure. The second limiting openings 110 at both ends are interference fit to the puncture needle 111. The size of the opening matches the puncture needle 111. After insertion, it will not loosen. The gap between the needle body and the opening can just fix the needle tip without squeezing and deforming the needle body, ensuring that the puncture needle is firmly installed. A motor 121 is mounted on top of the fixing plate 104. The motor 121 has a heat sink on its casing, preventing overheating even after prolonged operation. It operates very quietly; a slight rotational sound can only be heard when the operator is very close, ensuring it does not interfere with communication during surgery. Its output end connects to a second gear 119. A first gear 117 on top of the changing frame 106 meshes with the second gear 119. The gear surface has an anti-rust coating, preventing rusting even after long-term use. The teeth mesh tightly without slippage during rotation, and the meshing sound is very quiet. When the motor 121 operates, it drives the changing frame 106 to rotate via gear transmission, causing the two puncture needles 111 to alternately align with the infusion bottle. The infusion monitoring function of the replacement mechanism is compatible with existing infusion detection devices (such as the infusion alarm disclosed in utility model patent CN221888891U), monitoring the liquid in the drip tube of the infusion tubing 107. When the detected liquid level is low, the internal controller activates the replacement mechanism.

[0058] The changing frame 106 is fitted onto the lifting rod 101 via a sliding ring 115. The gap between the sliding ring 115 and the lifting rod 101 is uniform, preventing jamming during vertical sliding. A rotating ring 116 is fitted onto its outer wall, with grease between its inner and outer rings, ensuring smooth and unobstructed rotation. This allows the changing frame 106 to both rotate and slide vertically. A lifting plate 105 is fixed to the outside of the sliding ring 115. The edge of the lifting plate 105 has graduations, which, along with markings on the fixing plate 104, allow for a clear view of the lifting height, facilitating precise control of the insertion depth of the puncture needle 111. The gears are located inside the lifting plate 105, preventing them from being exposed and accumulating dust. The output end of the electric push rod 122 at the top of the fixed plate 104 is connected to the lifting plate 105. The extension and retraction speed of the electric push rod 122 is stable. When pushing the changing frame 106 up or down, the puncture needle 111 will not wobble, ensuring accurate positioning when inserted into the infusion bottle. Its extension and retraction drive the changing frame 106 to rise and fall, realizing the insertion and removal action of the puncture needle 111. A rotating sleeve rod 120 also passes through the top of the fixed plate 104. The connecting shaft 118 inside the sleeve rod 120 can slide up and down. The fit clearance between the two is very small, and the connecting shaft 118 will not wobble when sliding up and down, ensuring that the second gear 119 is always aligned with the first gear 117. The second gear 119 is fixed at the bottom end of the connecting shaft 118, ensuring that the gears are always engaged when the changing frame 106 rises and falls.

[0059] Two L-shaped extension blocks 114 are mounted on one side of the replacement frame 106, corresponding to the two infusion bottle openings. The L-shaped ends of the extension blocks 114 are flat and can be inserted into the easy-open caps of the infusion bottles. When the removal action begins, the caps can be removed from the infusion bottle openings. When the puncture needle 111 is pulled out of the infusion bottle, the outer end of the extension block 114 will open the easy-open cap, eliminating the need for manual opening and reducing the risk of contamination. In conventional operations, spare bottles need to be opened in advance, leading to the risk of rubber stopper contamination. This device allows spare bottles to be used with their caps on. Only during the replacement procedure, when the puncture needle 111 is pulled out of the old bottle or moved, is the easy-open cap of the new bottle automatically hooked and opened by the outer end of the extension block 114 using the movement of the robotic arm. This "use-and-open" method ensures that the rubber stopper of the infusion bottle is not exposed to air until one second before puncture, greatly improving the safety of the procedure. A protective sleeve 108 is threaded onto the connecting seat 113 on one side of the fixing plate 104. The protective sleeve 108 is securely tightened and will not loosen. A rubber plug 112 is embedded in the bottom opening of the protective sleeve 108. The rubber plug 112 has moderate hardness, allowing the puncture needle 111 to be inserted smoothly. After removal, the needle hole closes quickly, maintaining a sterile internal environment. The length of the protective sleeve 108 is sufficient to cover the entire tip of the puncture needle 111, ensuring that the needle tip is not exposed when not in use, preventing accidental puncture or contamination. When replacing two puncture needles 111, the unused puncture needle 111 is inserted into the rubber plug 112 and protected by the protective sleeve 108. Therefore, the rubber plug 112 not only serves a fixing function but, more importantly, acts as a "sterile residence chamber." When the puncture needle 111 is in a waiting state, its tip is completely embedded inside the rubber plug 112. The high elasticity of the rubber tightly wraps around the needle body, isolating it from external air and aerosols, preventing the needle tip from drying out or becoming contaminated. When the system command is switched, the electric push rod 122 drives the needle to be pulled out directly without the need for manual removal of the needle cap, and it immediately enters the working state.

[0060] One end of the handle 22 is fitted with a needle 23, which is securely connected to the handle 22 without any looseness when rotated. The needle tip is sharp and smooth, allowing for precise cutting of the lens during surgery and minimizing damage to surrounding tissues. The other end connects to the machine body via a connecting cable 25. The infusion port 24 and aspiration port 26 on the side connect to the pressurized infusion interface 15 and the corresponding aspiration interface on the machine body, respectively. The interfaces have annular protrusions to increase sealing when connected to the tubing. The insertion and removal force is moderate, allowing the doctor to operate with one hand without strenuous insertion or removal. During surgery, the infusion port 24 delivers balanced saline solution to maintain intraocular pressure, while the aspiration port 26 removes emulsified lens debris. The grip portion of the handle 22 is curved to fit the natural curve of the palm and is covered with anti-slip silicone. The silicone sleeve is of uniform thickness, providing a comfortable grip and reducing fatigue during prolonged operation. Even with sweaty palms, the grip will not slip.

[0061] Working principle: In use, first insert an infusion bottle with its opening facing down into the U-shaped limiting port 109. The swing head 103 hangs down naturally, touching the bottom of the bottle. Gently shake the device to confirm that the infusion bottle is firmly fixed. At this time, one of the puncture needles 111 is aligned with the opening of one of the infusion bottles, and the easy-open cap of the infusion bottle is opened. Adjust the height of the lifting rod 101 through the solution suspension rod control button 19, start the electric push rod 122 to retract, driving the changing frame 106 to rise. The puncture needle 111 slowly pierces the infusion bottle, and the liquid flows into the device pipeline through the infusion tube 107. After the surgery begins, the doctor holds the handle 22 and adjusts the parameters through the foot pedal controller 9. The cable of the foot pedal controller 9 is long enough to extend from the device to the side of the operating table. The surface has a wear-resistant braided layer, which is not easy to be broken by stepping on it. The bottom has an anti-slip pad, so it will not move when stepped on. The pedal has three positions, each corresponding to a different operating mode. The stepping force is moderate, so the doctor will not feel ankle pain even after a long period of operation. The display 2 displays data such as infusion pressure and flow rate in real time, which is convenient for monitoring at any time. During the operation, the remaining infusion bottles are inserted into another U-shaped limiting port 109, and at the same time, the extension block 114 is inserted into the easy-open cap of the bottle opening.

[0062] When the infusion bottle in use is nearly empty, the device automatically initiates the replacement procedure: the electric push rod 122 extends, causing the replacement frame 106 to descend, and the puncture needle 111 on one side is pulled out of the empty bottle. During the removal process, the extension block 114 on the other side removes the easy-open cap; the motor 121 starts, causing the replacement frame 106 to rotate via gear transmission, and the other puncture needle 111 is aligned with the new infusion bottle; the electric push rod 122 retracts, the new puncture needle 111 is inserted into the infusion bottle, and the infusion begins to be delivered; at the same time, the old puncture needle 111 rotates with the replacement frame 106 to above the protective cylinder 108, and the electric push rod 122 extends appropriately, allowing the old puncture needle 111 to be inserted into the rubber stopper 112 for storage. The entire replacement process requires no manual intervention. When the device is running, the heat dissipation window 13 continuously dissipates heat, and the internal fan automatically adjusts its speed according to the temperature. When the temperature is low, it operates at a low speed with almost no noise, and only increases its speed when the temperature rises to avoid continuous noise interfering with the operation. The noise level is controlled below 50 decibels, which will not interfere with communication during surgery. All components work together smoothly, from fixing the infusion bottle to automatic replacement, from fluid delivery to parameter adjustment, all of which can work stably, making it suitable for the precise needs of ophthalmic phacoemulsification surgery, effectively shortening the operation time and reducing the risk of infection.
