[0002] Phacoemulsification is a surgical method for dissolving and aspirating cataracts through ultrasonic technology.

[0003] During the operation, the doctor uses a phacoemulsification device to transmit ultrasonic energy into the eye through a small incision, and uses high-frequency ultrasonic waves to crush the cloudy lens nucleus into a milky state, and aspirates these emulsified lens tissues through an aspiration system. Among them, the suction handle is an important component of the phacoemulsification device.

[0004] The suction handle can receive an electrical signal from the console of the phacoemulsification device to which it belongs through a cable and convert it into mechanical motion. The perfusion catheter and the aspiration catheter of the existing phacoemulsification device are connected to the suction handle through the suction port and the perfusion port on the suction handle. The connection between the perfusion catheter and the aspiration catheter and the suction handle is easily separated from each other under external force pulling, affecting the normal progress of the operation. And after long-term use, the connection between the cable and the suction handle is easily damaged due to excessive bending. Therefore, a suction handle is needed to solve the above problems.

[0026] The anti-disengagement component 5 includes a V-shaped frame 501, and the V-shaped frame 501 is arranged on the front surface of the mounting plate 102.

[0027] Among them; the anti-disengagement component 5 further includes a connecting plate 502, a bi-directional screw 503, a knob 504 and a base 505. Both ends of the connecting plate 502 are connected to the V-shaped frame 501. The upper end of the bi-directional screw 503 passes through the connecting plate 502 and is connected to the knob 504. The thread directions of both ends of the bi-directional screw 503 are opposite. The bi-directional screw 503 is rotationally connected to the connecting plate 502 through a bearing member. By providing the V-shaped frame 501, it is convenient to install and fix the connecting plate 502 and the bi-directional screw 503. By rotating the knob 504, the bi-directional screw 503 can be effectively driven to rotate synchronously.

[0028] Among them; the bidirectional screw 503 is rotatably connected to the base 505. Limit clamping bars 506 are threadedly connected to both the upper and lower ends of the bidirectional screw 503. Limit sliding rods 507 are provided at both ends of the upper surface of the base 505. The upper ends of the limit sliding rods 507 pass through the limit clamping bars 506 and are connected to the connecting plate 502.

[0031] Working principle: By rotating the knob 504, the bidirectional screw 503 can be effectively driven to rotate synchronously. By rotating the bidirectional screw 503 and under the limiting action of the limit sliding rods 507, the two limit clamping bars 506 move along the vertical direction of the bidirectional screw 503, approaching or moving away from each other. When the two limit clamping bars 506 approach each other, the limit clamping bars 506 can effectively clamp the plug joints of the perfusion catheter and the suction catheter, and are stuck outside the annular protrusion on the outer surface of the plug joint, effectively preventing the perfusion catheter and the suction catheter from detaching from the handle body 1, with simple operation.

[0032] Furthermore, by providing the limit rollers 603, the wire 2 can be effectively limited and supported, preventing the connection between the wire 2 and the handle body 1 from being damaged due to excessive bending, and extending the service life of the wire 2.
