Description

Technical Field

[0001] The utility model relates to the field of ophthalmic cataract ultrasonic emulsification devices, in particular to a vacuum waste suction box for ultrasonic emulsification surgery. Background Art

[0002] Cataracts are a common eye condition in ophthalmic surgery, and one treatment option is phacoemulsification. This procedure uses ultrasonic energy to emulsify and remove the cloudy lens, while simultaneously implanting an intraocular lens to restore vision. During surgery, a large amount of debris and waste fluid is generated. If not promptly processed, this waste can not only affect the surgical field of view but also adversely impact surgical outcomes and patient safety.

[0003] Currently, the most common waste disposal solution used in phacoemulsification surgery is a peristaltic pump system. This system uses a roller to squeeze a silicone tube to create a vacuum, thereby sucking away debris and waste fluids generated during surgery. However, the peristaltic pump solution has exposed a series of shortcomings in practical applications:

[0004] 1. The peristaltic pump requires a roller to roll and squeeze the silicone tube to gradually generate negative pressure, which results in a significant time delay in the rise of negative pressure. This makes it difficult for doctors to accurately control the changes in negative pressure during surgery, affecting the smoothness and effectiveness of the operation.

[0005] 2. Due to the working principle of peristaltic pumps, the negative pressure they generate often fluctuates greatly, forming a curved change. This unstable negative pressure state poses additional challenges to the doctor's surgical operation, requiring the doctor to have higher operating skills and experience.

[0006] 3. Solid matter generated during surgery can easily accumulate in the silicone tube, leading to blockage. Once a blockage occurs, the roller will get stuck, affecting the normal removal of waste. This not only prolongs the operation time but may also increase surgical risks.

[0007] 4. Because peristaltic pumps involve the coordinated work of multiple mechanical components, these components are easily damaged by wear or failure. Once damaged, they need to be replaced or repaired in a timely manner, increasing the maintenance cost and use cost of the equipment. Summary of the Invention

[0008] In order to solve the above problems, the utility model provides a vacuum waste suction box for phacoemulsification surgery, which can quickly reach and maintain a stable negative pressure state in the waste liquid storage cavity by directly connecting to an external negative pressure device.

[0009] To achieve the above purpose, the technical solution adopted by the present invention is: a vacuum waste suction box for phacoemulsification surgery, comprising a vacuum waste suction box, wherein a waste liquid storage cavity is provided in the vacuum waste suction box,

[0010] The empty waste suction box is provided with a negative pressure suction interface and a waste liquid suction interface which are respectively connected to the waste liquid storage cavity; the negative pressure suction interface is externally connected to a negative pressure device and makes the waste liquid storage cavity in a negative pressure state, and the waste liquid suction interface is externally connected to a suction tube.

[0011] Further discussion, an isolation plate is provided in the waste liquid storage cavity for separating the negative pressure suction interface and the waste liquid suction interface, and a waste liquid suction channel is formed between the isolation plate and the inner wall of the waste liquid storage cavity, and the two ends of the waste liquid suction channel are respectively connected to the waste liquid suction interface and the waste liquid storage cavity.

[0012] It is further discussed that the waste liquid suction channel is an "L"-shaped structure, and the output end of the liquid suction channel is far away from the negative pressure suction interface.

[0013] Further discussion, there are several structural reinforcement ribs evenly distributed inside the waste liquid storage cavity.

[0014] Further discussion, a retaining groove is provided on both sides of one end of the vacuum waste suction box.

[0015] Further discussion, the upper end of the vacuum waste suction box is also provided with pipe clamping grooves on both sides.

[0016] Further discussion, a connecting portion is protruding from the upper end of the vacuum waste suction box, wherein a negative pressure suction interface is vertically arranged above the connecting portion, wherein a waste liquid inlet interface is horizontally arranged on one side of the connecting portion, and the waste liquid inlet interface faces the tube slot.

[0017] Further discussion, the negative pressure suction interface is provided with a sealing gasket.

[0018] In further discussion, the vacuum waste suction box includes a left waste suction shell and a right waste suction shell, and the left waste suction shell and the right waste suction shell are connected by ultrasonic welding.

[0019] The beneficial effects of the present invention are:

[0020] 1. By directly connecting to an external negative pressure device, the waste fluid storage chamber quickly reaches and maintains a stable negative pressure state. Compared to traditional peristaltic pump solutions, this significantly reduces the time delay for negative pressure to rise, enabling doctors to more precisely control the surgical process and improving surgical efficiency. The waste fluid suction channel effectively prevents solid matter in the waste fluid from directly impacting the negative pressure suction interface, reducing the risk of clogging and wear and extending the service life of the device.

[0021] 2. The "L"-shaped waste liquid suction channel and its output end design away from the negative pressure suction interface effectively prevent solid matter in the waste liquid from directly impacting the negative pressure system, greatly reducing the risk of blockage and extending the service life of the equipment.

[0022] 3. The structural reinforcement ribs evenly distributed in the waste liquid storage chamber enhance the overall structural strength of the suction box, enabling it to withstand greater pressure without deformation or rupture, thereby improving the durability and reliability of the equipment.

[0023] 4. The design of the positioning slot and the tube slot makes the installation and removal of the suction box simple and quick. It also facilitates the connection operation during the operation and the cleaning and maintenance work after the operation, reducing maintenance costs and time costs.

[0024] 5. The isolation plate effectively isolates the vacuum suction port from the waste fluid suction port, preventing contaminants in the waste fluid from directly contacting the vacuum system. This ensures the system is clean and functioning properly, reducing the risk of equipment failure due to contamination. Furthermore, the clear waste fluid flow path facilitates thorough cleaning and disinfection after surgery. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] See also Figure 1-3 As shown, the present invention relates to a vacuum waste suction box 1 for phacoemulsification surgery, comprising a vacuum waste suction box 1, wherein a waste liquid storage cavity 10 is provided in the vacuum waste suction box 1, and the vacuum waste suction box is provided with a negative pressure suction interface 13 and a waste liquid suction interface 15 respectively connected to the waste liquid storage cavity 10; the negative pressure suction interface 13 is externally connected to a negative pressure device to keep the waste liquid storage cavity 10 in a negative pressure state, and the waste liquid suction interface 15 is externally connected to a suction tube. An isolation plate 16 is provided in the waste liquid storage cavity 10 to separate the negative pressure suction interface 13 and the waste liquid suction interface 15, and a waste liquid suction channel 19 is formed between the isolation plate 16 and the inner wall of the waste liquid storage cavity 10, and the two ends of the waste liquid suction channel 19 are respectively connected to the waste liquid suction interface 15 and the waste liquid storage cavity 10.

[0030] Its beneficial effects:

[0031] The isolation plate 16 provided in the waste liquid storage chamber 10 effectively separates the negative pressure suction port 13 from the waste liquid suction port 15, preventing contaminants or debris in the waste liquid from directly contacting the negative pressure suction system. This ensures the cleanliness and proper operation of the negative pressure system and reduces the risk of equipment failure due to contamination. The waste liquid suction channel 19 formed between the isolation plate 16 and the inner wall of the waste liquid storage chamber 10 provides a clear flow path for the waste liquid. This design helps ensure that the waste liquid can smoothly enter the waste liquid storage chamber 10, preventing waste liquid from splashing or accumulating in undesirable areas during the suction process. At the same time, by connecting the two ends of the waste liquid suction channel 19 to the waste liquid suction port 15 and the waste liquid storage chamber 10, respectively, a highly efficient suction system is formed. The negative pressure device generates negative pressure through the negative pressure suction port 13, smoothly drawing the waste liquid into the waste liquid storage chamber 10 through the suction tube, the waste liquid suction port 15, and the waste liquid suction channel 19, thereby improving suction efficiency. The isolation plate 16 not only isolates and guides the waste liquid, but also enhances the structural stability of the waste liquid storage chamber 10. It acts as a support structure within the cavity, helping to resist the risk of deformation or rupture due to waste liquid accumulation or external forces.

[0032] The design of the waste liquid suction channel 19 and the isolation plate 16 makes the suction box more convenient to clean and maintain. The operator can flush or clean the waste liquid storage chamber 10 and the suction channel through a specific interface or channel to ensure the sanitation and long-term stable operation of the equipment.

[0033] To further discuss, the waste liquid suction channel is an “L”-shaped structure, and the output end of the liquid suction channel is far away from the negative pressure suction interface 13 .

[0034] The beneficial effect is that positioning the output end of the liquid suction channel away from the negative pressure suction port 13 prevents impurities or particulate matter in the waste liquid from directly impacting the negative pressure suction port 13, reducing wear and damage to the negative pressure device. This helps extend the life of the negative pressure device and reduces the cost of repair and replacement due to device damage.

[0035] Since the design of the "L"-shaped channel reduces the direct impact of waste liquid on the negative pressure suction interface 13, the stability of the negative pressure system can be maintained. During surgery, a stable negative pressure state is crucial to ensuring surgical effectiveness and patient safety. In summary, the liquid suction channel adopts an "L"-shaped structure, and its output end is far away from the negative pressure suction interface 13, which shows significant beneficial effects in reducing the risk of blockage, optimizing the flow of waste liquid, protecting the negative pressure system, improving negative pressure stability, and facilitating cleaning and maintenance. This design not only improves the performance and reliability of the vacuum waste suction box 1 for ultrasonic emulsification surgery, but also provides a more efficient and safe solution for waste disposal during surgery.

[0036] To further discuss, a plurality of structural reinforcement ribs 17 are evenly distributed inside the waste liquid storage cavity 10 .

[0037] The structural reinforcement ribs 17 serve as support structures within the waste liquid storage chamber 10, effectively dispersing and resisting stress and deformation caused by waste liquid accumulation or external pressure. This evenly distributed reinforcement design significantly enhances the overall structural strength of the waste liquid storage chamber 10, allowing it to withstand greater loads without deformation or cracking.

[0038] To further discuss, a retaining groove 11 is provided on both sides of one end of the vacuum waste suction box 1 .

[0039] Its beneficial effects: The design of the positioning slot 11 enables the vacuum waste suction box 1 to be easily and quickly installed in a specific position or connected with other accessories. Through a simple snap-in action, a stable installation can be achieved without the need for additional tools or complicated operating steps, thereby improving installation efficiency. The positioning slot 11 matches the buckle or slot on the matching accessory, which can ensure that the vacuum waste suction box 1 has a high degree of positioning accuracy during installation. This design prevents the risk of performance degradation or damage due to improper installation position, and ensures the stability and reliability of the equipment during use. In addition to being easy to install, the design of the positioning slot 11 also allows the vacuum waste suction box 1 to be easily disassembled and replaced when needed. This design facilitates the daily maintenance and maintenance of the equipment, reducing maintenance costs and time costs.

[0040] Furthermore, the upper side of the vacuum waste suction box 1 is also provided with tube retaining grooves 12. This advantageous effect is that the design of the tube retaining grooves 12 provides an orderly, fixed position for the hoses connected during surgery. This helps reduce swinging and tangling of the hoses during surgery, and reduces the risk of accidental collisions or dislodging caused by the disorganized hoses. The tube retaining grooves 12 securely hold the hose connected to the waste fluid suction port 15, preventing it from being dislodged due to accidental movement or external forces during surgery. This stability ensures that waste fluids and debris during surgery are promptly and effectively removed. Furthermore, the operator can quickly and accurately secure the hose in the tube retaining grooves 12 without the need for additional securing tools or complicated procedures. This convenience improves the efficiency of surgical preparation and cleanup, saving the surgeon valuable time. The design of the tube retaining grooves 12 also protects the hoses from external wear and tear. In a surgical environment, hoses are susceptible to contact and collision with various equipment and personnel. The presence of the tube retaining grooves 12 reduces this unnecessary contact and extends the hose's service life.

[0041] To further discuss, a connection portion 18 is protruding from the upper end of the vacuum waste suction box 1, wherein the negative pressure suction interface 13 is vertically arranged above the connection portion 18, wherein a waste liquid inlet interface 14 is horizontally arranged on one side of the connection portion 18, and the waste liquid inlet interface 14 faces the tube slot 12.

[0042] The beneficial effect is that the negative pressure suction port 13 is vertically positioned above the connecting portion 18. This layout not only helps reduce interference between the ports, but also facilitates quick and accurate connection to the negative pressure device. Simultaneously, the waste liquid inlet port 14 is positioned horizontally on one side of the connecting portion 18, facing the cable retaining slot. This design allows waste liquid to flow smoothly into the waste liquid storage chamber 10 while avoiding interference with other components such as the hose.

[0043] The rationally positioned interfaces facilitate connections and operations during surgery. For example, the high-positioned suction interface 13 allows for easy docking of negative pressure equipment, while the horizontal placement of the waste fluid inlet interface 14 facilitates access to suction tubes or other delivery devices, thereby improving the efficiency of the entire surgical process.

[0044] Furthermore, the negative pressure suction port 13 is equipped with a sealing gasket. This sealing gasket serves as a key sealing element between the negative pressure suction port 13 and the external negative pressure device, effectively preventing gas or liquid leakage at the interface. This sealing ensures that the waste liquid storage chamber 10 can maintain a continuous negative pressure state, thereby ensuring that waste liquid and debris can be effectively suctioned during surgery.

[0045] Furthermore, the vacuum waste suction box 1 comprises a left waste suction shell and a right waste suction shell, which are connected via ultrasonic welding. Separating the left and right shells of the vacuum waste suction box 1 and connecting them via ultrasonic welding effectively enhances the structural strength of the entire suction box. Ultrasonic welding quickly bonds the two shells together, forming a single integrated structure that improves overall compressive strength and durability.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
