[0043] The present utility model provides a drug powder injection device, which can be used for endoscopic surgery, etc., but is not limited here.

[0044] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the powder injection device includes a device housing 10, a blower 20, an oscillating platform 30, a connector 40 and a conduit 50; the blower 20 is arranged in the device housing 10; the oscillating platform 30 is arranged on the device housing 10; the connector 40 is fixed on the oscillating platform 30, and the device 50 is connected to the device housing 10. Figure 1 、 Figures 7 to 9 The connector 40 has an air inlet 40a, a powder inlet 40b and a powder outlet 40c. The air inlet 40a of the connector 40 is connected to the air outlet end of the fan 20, and the powder inlet 40b of the connector 40 is suitable for connecting to the powder container 100; the proximal end of the conduit 50 is connected to the powder outlet 40c of the connector 40, and the distal end of the conduit 50 is suitable for extending into the target injection position.

[0045] In this embodiment, the device housing 10 may include two outer shells, which enclose a space for mounting components such as a power supply, a circuit board, a blower 20, and its air duct. The overall housing 10 may be shaped like a handle, for example, to facilitate gripping by medical personnel and improve surgical efficiency. Of course, in other embodiments, the device housing 10 may be assembled from more housing components and may be configured in other shapes, which are not limited here.

[0046] The main body cavity of the connector 40 of this embodiment may be provided with an air inlet channel, a powder inlet channel, and a powder outlet channel. These channels may directly serve as pathways for drug and gas delivery, or delivery tubes may be arranged within each channel to ensure good sealing and prevent drug and gas leakage. The specific structure of the connector 40 is not limited herein.

[0047] The fan 20 can blow out an air flow, and the air flow flows along the air path. After the catheter 50 is connected to the air path through the connector 40, the air flow can quickly blow out the accumulated medicine powder. At the same time, when the catheter 50 is inserted, the air flow inside the catheter 50 can prevent body fluids from entering, avoiding the contact between body fluids and medicine powders in the catheter 50 and causing blockage.

[0048] The oscillating platform 30 serves as a supporting platform for the connector 40 , and a plurality of vibration motors 32 can be used therein to oscillate the medicine. The oscillating platform 30 can disperse agglomerated or accumulated medicine powder and enable the medicine powder in the container to fall into the connector 40 more quickly.

[0049] Please combine Figure 1 、 Figures 11 to 13 Catheter 50 is an invasive catheter made of medical-grade materials, and can be made of highly lubricating and non-stick materials such as PTFE, though this is not a limitation. Preferably, catheter 50 comprises a catheter body 51, a connecting piece 52, and a connector 53. The tail end of catheter body 51 has a flared opening, the interior of connecting piece 52 has internal threads, and the front end of connector 53 has external threads. The internal and external threads cooperate to clamp the flared opening, securing catheter body 51 and connector 53.

[0050] It can be understood that the present invention realizes automatic oscillation and dispersion of the powder inside the instrument body and the connected conduit 50 by providing an oscillating platform 30 on the instrument housing 10, which can prevent the accumulation of powder in the instrument cavity and the conduit 50, greatly improving the efficiency of powder injection, and eliminating the need for medical staff to shake the injection instrument, thereby improving the convenience of using the powder injection instrument.

[0051] In order to further improve the efficiency of powder injection and the convenience of instrument operation, refer to Figure 1 、 Figures 7 to 10 In one embodiment, the connector 40 may include a housing 41, a trigger 42, and an internal valve 43.
