[0043] The conveyor in the prior art uses a light source to directly illuminate the optical fiber, thereby providing light to the medical glue delivery tube. However, the light source used in the prior art to directly illuminate the optical fiber is relatively weak; and the optical fiber often only reflects strong light at the two ends, and the brightness of the rest is relatively weak, resulting in unclear blood vessel visualization.

[0044] To solve the above problems, this embodiment provides a medical glue conveyor. Figure 1 , Figure 5 , Figure 6 and Figure 8 , including a delivery tube 10 and a light source assembly 20. The delivery tube 10 is provided with a first lumen 11 and a second lumen 12. The first lumen 11 is used to deliver medical glue, and the second lumen 12 is provided with a plurality of optic fibers 100 of different lengths. The light source assembly 20 includes a light emitting element 21 and a condenser 22. The light emitting element 21 is placed on one side of the condenser 22. The input end of the optical fiber 100 can extend out of the delivery tube 10 and be placed on the other side of the condenser 22, so that the light source of the light emitting element 21 is concentrated by the condenser 22 and irradiated on the input end of the optical fiber 100. The condenser 22 is used to enhance the light source to concentrate the brightness of the optical fiber 100. A plurality of optical fibers 100 of different lengths are provided, so that the ends of the optical fiber 100 are at different positions to illuminate multiple positions of the varicose blood vessels, thereby improving the convenience and accuracy of the delivery of medical glue.

[0045] Further, see Figure 4 The light source assembly 20 also includes a light shield tube 23, which is arranged on the side of the delivery tube 10. The light emitting element 21, the condenser 22 and the input end of the optical fiber 100 are coaxially arranged in the light shield tube 23. In this embodiment, the light emitting element 21 is configured as an LED lamp, and the LED lamp is arranged at the end of the light shield tube 23. The LED lamp and the light shield tube 23 can be interference fit or glued. The condenser 22 is arranged inside the light shield tube 23 and is coaxial with the LED lamp to maximize the focus of the light source of the LED lamp. Figure 6 and Figure 7The other end of the light shield tube 23 is provided with a support member 24, which can be set as a wooden plug or a plastic plug. The support member 24 and the light shield tube 23 can be threaded, glued or snap-connected, etc. Those skilled in the art can choose different connection methods according to actual conditions, which will not be listed here one by one. A through hole is provided on the support member 24 at a position coaxial with the condenser 22, and the input end of the optical fiber 100 is snapped into the through hole to be coaxial with the condenser 22. The optical fiber 100 and the support member 24 are interference fit.

[0046] Specifically, the number of optical fiber filaments 100 corresponds to the number of the second tube cavity 12, the light emitting element 21, the condenser 22 and the light shield tube 23. Furthermore, the light shield tube 23 is made of a non-transparent material, such as metal or plastic, to prevent the light source of the LED lamp from being dispersed.

The switch 33 can control the light-emitting element 21 and the battery 32 separately to realize the operation of turning off only the light-emitting element 21 and turning off the battery 32 to turn off the light-emitting element 21. Specifically, the battery 32, the light-emitting element 21 and the switch 33 are all set to an asymmetric structure to avoid reverse connection of the positive and negative poles during installation, avoid damage to the circuit board 31, and improve the production efficiency and qualified rate of the medical glue conveyor.

[0049] Furthermore, a battery clip 34 is provided on the circuit board 31, and the battery 32 is fixed to the circuit board 31 through the battery clip 34. Specifically, the battery 32 and the battery clip 34 are snap-fitted to avoid welding the battery 32 to the circuit board 31, thereby reducing contamination to the medical glue conveyor.

[0050] Further, see Fig.11, multiple light-emitting components 21 and batteries 32 are provided, and all light-emitting components 21 and all batteries 32 are connected in parallel; the condenser 22, the light shield tube 23 and the optical fiber filament 100 correspond to the light-emitting components 21 one by one, and the battery clip 34 corresponds to the battery 32 one by one. Multiple light-emitting components 21 and multiple batteries 32 are connected in parallel on the circuit board 31. Even if one of the batteries 32 is not installed or one of the light-emitting components 21 is damaged, it will not affect the medical glue surgery. In addition, multiple batteries 32 and light-emitting components 21 can provide different brightness intensities for the medical glue surgery, which increases the flexibility of the medical glue surgery. In this embodiment, the light-emitting components 21 are preferably set to three, and the batteries 32 and battery clips 34 are each provided with four.

The switch 33 is exposed on the surface of the first housing plate 41 or the second housing plate 42 for easy pressing.

[0052] Further, see Fig. 9 and Fig.10 , both ends of the second lumen 12 are provided with plugging members 50 to seal the second lumen 12. Prevent blood or medical glue from entering the second lumen 12 and affecting the brightness of the optical fiber 100. The plugging member 50 can be set as a rubber plug or a silicone plug. The connection method between the plugging member 50 and the second lumen 12 includes but is not limited to glue bonding, snap-fit ​​structure or thermal fusion, etc. Those skilled in the art can select different connection methods according to actual conditions, which will not be listed here one by one. .

[0053] Furthermore, a connector 60 is provided at the input end of the delivery tube 10 for connecting with an injection tool, which may be a general syringe, or a special injection gun or injection pump, etc., to inject the medical glue into the first lumen 11. Specifically, the connector 60 is a connecting tube, which facilitates the injection tool to inject the medical glue.
