Description

Technical Field

[0001] The utility model belongs to the technical field of ultrasonic emulsification irrigation and suction devices, in particular to an irrigation and suction device for ophthalmic ultrasonic emulsification surgery. Background Art

[0002] In the field of ophthalmic surgery, especially in the surgical treatment of intraocular diseases such as cataracts, the use of ultrasonic emulsification devices is required. Ultrasonic emulsification devices are indispensable key equipment. Ultrasonic emulsification devices mainly use ultrasonic generators to generate high-frequency ultrasonic waves. The ultrasonic energy is converted into mechanical vibrations through the transducer in the ultrasonic emulsification handle and transmitted to the emulsification needle. The high-frequency vibration of the emulsification needle acts on the turbid lens nucleus, emulsifying it into small pieces, and the emulsified lens nucleus fragments and irrigation fluid are sucked out of the eye together through the attraction generated by the negative pressure suction device. At the same time, irrigation fluid is continuously injected into the eye during the operation to keep the surgical field clear and the eye moist.

[0003] However, despite the important role of phacoemulsification devices in cataract surgery, existing phacoemulsification irrigation and aspiration devices still have shortcomings in many aspects. In particular, these devices face many challenges in terms of liquid flow control, ease of operation, equipment stability, and patient comfort. For example, the complex pipeline layout and connection method make it difficult to accurately control the flow of liquid, which not only increases the difficulty of surgical operations, but also increases the risk of accidents during surgery. Once the irrigation fluid and the aspiration fluid interfere with each other, it is very easy to affect the clarity of the surgical field and the accuracy of the operation, thereby affecting the surgical effect.

[0004] Therefore, the inventors are committed to designing a phacoemulsification irrigation and suction device to solve the above problems. Utility Model Content
