[0042] The utility model provides a powder injection handle, which can be used as a handle of a powder medicine injection device and applied to endoscopic surgery, etc., which is not limited here.

[0043] Reference Figures 1 to 4 In one embodiment of the present invention, the powder injection handle 100 includes a handle housing 10, a fan 20 and an oscillating platform 30; the handle housing 10 is provided with an air supply channel 11; the fan 20 is arranged in the handle housing 10, and the air outlet end of the fan 20 is connected to one end of the air supply channel 11, and the other end of the air supply channel 11 is suitable for connecting to the air inlet of ancillary equipment such as a connector 200; the oscillating platform 30 is arranged on the handle housing 10, and the oscillating platform 30 is suitable for fixing the ancillary equipment and vibrating the ancillary equipment.

[0044] In this embodiment, the handle housing 10 may include two outer shells, which may be fixed together by threaded connection, gluing, or clamping, and enclose an installation space for installing components such as the power supply 40, circuit board, blower 20, and its air duct. The air supply channel 11 may be formed by a cavity inside the housing, or may be an air duct provided inside the housing. The handle housing 10 is in the shape of a handle as a whole, which is convenient for medical staff to hold and helps improve the efficiency of the operation. Of course, in some other embodiments, the handle housing 10 may also be assembled from more housings, which is not limited here.

[0045] Combine Figure 1 and Figure 4 The air outlet of the fan 20 blows out air, and the air flow flows along the air supply channel 11. After the interventional catheter 300 is connected to the air path through the connector 200 and other supporting equipment, the air flow can quickly blow out the accumulated medicine powder in the cavity or pipe. At the same time, when the interventional catheter 300 is sent to the target position, the air flow inside the interventional catheter 300 can prevent body fluids from entering, thereby avoiding the contact between body fluids and medicine powders in the catheter 300 to cause tube blockage.

[0046] The oscillation platform 30 serves as a support platform for ancillary equipment such as the connector 200. It can be equipped with several vibration motors to achieve oscillation of the medicine. The oscillation platform 30 can disperse the agglomerated or accumulated medicine powder and make the medicine powder in the container fall into the ancillary equipment such as the connector 200 more quickly.

[0047] It can be understood that the present invention achieves automatic dispersion of the powder by setting an oscillation platform 30 on the handle shell 10 to shake and oscillate the powder in the supporting instrument, without the need for medical staff to perform manual shaking operations, effectively avoiding the problem of blockage caused by accumulation of powdered drugs, and greatly improving the efficiency of powder injection.

[0048] In order to further improve the powder dispersion effect and enhance the convenience of operation, refer to Figure 4 、 Figure 6 and Figure 7 In one embodiment, the oscillation platform 30 may include an oscillation housing 31 and at least one vibration motor, wherein the at least one vibration motor is installed in the oscillation housing 31. The oscillation housing 31 may include an upper shell and a lower shell, and the upper shell and the lower shell may be fixed by threaded connection, gluing, or clamping. Preferably, the at least one vibration motor includes a first vibration motor 321 and a second vibration motor 322, wherein the first vibration motor 321 is used to drive the supporting device to vibrate along a first direction, and the second vibration motor 322 is used to drive the supporting device to vibrate along a second direction; wherein the first direction and the second direction are different directions, such as the first direction is the height direction of the handle when in use, and the second direction is the length or width direction of the handle when in use.

[0049] In order to improve the connection reliability between the powder injection handle 100 and the supporting equipment such as the connector 200, and to better transmit the vibration to the supporting equipment, in one embodiment, the oscillation platform 30 may be provided with a mounting slot 31a, which is suitable for clamping the protrusion of the supporting equipment. The mounting slot 31a may be a dovetail groove, etc., which is not limited here.

[0050] In this embodiment, the oscillating platform 30 is connected to the handle housing 10. The oscillating platform 30 is a movable component and can rotate relative to the handle housing 10. Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The oscillation housing 31 is provided with a snap-fitting protrusion 311, and the handle housing 10 is provided with a groove 10b that snaps in with the snap-fitting protrusion 311. The oscillation platform 30 is snap-fitted to the handle housing 10. In this way, the oscillation platform 30 can vibrate with a greater amplitude without being restricted by the handle housing 10.

[0051] Specifically, the snap-fit ​​protrusion 311 may be spherical, and the outer periphery of the snap-fit ​​protrusion 311 is wrapped with a cushion sleeve 312 , which can make the connection between the oscillation platform 30 and the handle housing 10 more flexible and reliable, and the vibration sound is smaller.

[0052] In addition, the main reference Figure 4 In some embodiments, the powder injection handle 100 may further include a power supply 40 disposed within the handle housing 10 and a control switch 50 disposed on the handle housing 10. The power supply 40 is electrically connected to the blower 20 and the vibration motor, and the control switch 50 is electrically connected to the blower 20 and the vibration motor of the oscillating platform 30. The power supply 40 may be an internal power supply or an external power supply; in this embodiment, a rechargeable battery is used. Of course, in other embodiments, the vibration motor may also be controlled by a separate circuit, which is not limited here.

[0053] Further, refer to Figure 3 and Figure 5 In this embodiment, the powder injection handle 100 further includes a blocking piece 12 for isolating the circuit between the power supply 40 and the control switch 50 . The blocking piece 12 is pluggably disposed on the handle housing 10 .

[0054] The blocking piece 12 can be made of any insulating material, with no particular limitation. A fixing slot 10a is provided on the inner wall of the handle housing 10, into which the blocking piece 12 is inserted. Blocking piece 12 must be removed before use. The presence of blocking piece 12 isolates the circuit, preventing accidental activation of the device during transportation or other circumstances.

[0055] In this embodiment, in order to facilitate the installation of various internal parts, such as Figure 4 As shown, a plurality of limit slots are provided in the handle housing 10 , which are used to respectively hold the power supply 40 , the fan 20 , the control switch 50 and the air guide tube constituting the air supply channel 11 .

[0056] The present invention also proposes an injection device, which includes a powder injection handle 100. The specific structure of the powder injection handle 100 refers to the above embodiment. Since the injection device proposed by the present invention includes all solutions of all embodiments of the above powder injection handle 100, it has at least the same technical effects as the above powder injection handle 100, which will not be elaborated here one by one.

[0057] Reference Figure 1 In one embodiment, the injection device further includes a connector 200 and a catheter 300. The connector 200 is disposed on the oscillating platform 30 of the powder injection handle 100. The air inlet of the connector 200 is connected to the air supply channel 11, and the powder inlet of the connector 200 is suitable for connecting to the powder container 400; the proximal end of the catheter 300 is connected to the powder outlet of the connector 200, and the distal end of the catheter 300 is suitable for extending into the target injection position.

[0058] It can be understood that the present invention realizes automatic oscillation and dispersion of the powder inside the connector 200 and the connected conduit 300 and the powder container 400 by arranging an oscillating platform 30 on the handle housing 10, which can prevent the powder from accumulating in the inner cavity of the instrument and the conduit 300, and can also make the powder in the powder container 400 fall into the connector 200 more quickly, thereby greatly improving the efficiency of powder injection, and eliminating the need for medical staff to shake the injection device, thereby improving the convenience of using the powder injection device.
