[0024] Example 1:

[0025] Reference Figures 1-5 An adjustable musculoskeletal ultrasound-guided injection device includes a frame 1 and an ultrasound guide 2 installed inside the frame 1. An adjusting rod 3 is rotatably connected to one side of the frame 1 via a locking bolt. An installation cylinder 4 is fixedly connected to one side of the adjusting rod 3. An injection needle 5 is installed inside the installation cylinder 4. A solution container 6 and a drive mechanism 7 are fixedly connected to one side of the installation cylinder 4. The injection needle 5 drives the drive mechanism 7. An atomizing pipe 8 is provided at the bottom of the installation cylinder 4, and the atomizing pipe 8 is connected to the drive mechanism 7 via a pipe. The drive mechanism 7 is connected to the solution container 6 via a pipe. The drive mechanism 7 includes components fixed to the side wall of the installation cylinder 4. A piston cylinder 71 has a piston rod 72 slidably connected inside it. The end of the piston rod 72 extends into the mounting cylinder 4. An inlet 73 and an outlet 74 are fixedly connected to the surface of the piston cylinder 71. The inlet 73 is connected to the solution box 6 through a pipe, and the outlet 74 is connected to the atomizing pipe 8 through a pipe. Several trapezoidal clamping blocks 9 are slidably connected to the inner bottom wall of the mounting cylinder 4. The trapezoidal clamping blocks 9 are arranged in a circumferential pattern at a distance along the inner wall of the mounting cylinder 4. The trapezoidal clamping blocks 9 are fixedly connected to the end of the piston rod 72. A return spring 10 is fixedly connected inside the mounting cylinder 4. The end of the return spring 10 is fixedly connected to the side wall of the trapezoidal clamping block 9.

[0026] In this invention, during use, the adjusting rods 3 on one side of the fixing frame 1 can be adjusted to drive the mounting cylinder 4 to adjust its angle by adjusting the locking bolts between them. This allows the bottom of the mounting cylinder 4 to be positioned above the injection site required by the patient. Then, the injection needle 5 is installed inside the mounting cylinder 4, so that the puncture point of the injection needle 5 penetrates the mounting cylinder 4 and is inserted into the patient's skin. When the injection needle 5 is installed on the inner wall of the mounting cylinder 4, the drive mechanism 7 is activated. The piston rod 72 inside the piston cylinder 71 is located inside the mounting cylinder 4. When the injection... When the needle 5 is installed in the mounting cylinder 4, it will squeeze the trapezoidal clamping block 9 to move to one side. Simultaneously, the piston rod 72 will move in the piston cylinder 71 as the trapezoidal clamping block 9 moves. When the piston rod 72 moves to the right, the one-way valve inside the outlet 74 will be opened, so as to deliver the disinfectant alcohol in the piston cylinder 71 to the atomizing pipeline 8 for spraying, thereby disinfecting the patient's puncture site. The trapezoidal clamping block 9 is set in multiple groups, and can also circumferentially clamp the surface of the injection needle 5, thereby improving the stability of the injection needle 5 during puncture.

[0027] When the injection needle 5 is disassembled, after the injection needle 5 separates from the trapezoidal clamping block 9, the trapezoidal clamping block 9 can be automatically reset under the spring force of the reset spring 10. When the trapezoidal clamping block 9 is reset, the piston rod 72 is moved to the left, thereby opening the one-way valve of the inlet 73, so that the disinfectant alcohol in the solution box 6 is injected into the piston cylinder 71 for storage, while the one-way valve of the outlet 74 is closed to prevent the alcohol from overflowing.

[0028] Example 2:

[0029] Reference Figure 5 Similar to Embodiment 1, but further: a support spring 11 is fixedly connected inside the fixing frame 1, an arc-shaped clamping plate 12 is fixedly connected to the end of the support spring 11, a pull rod 13 is fixedly connected to the surface of the arc-shaped clamping plate 12, the pull rod 13 is connected through the interior of the fixing frame 1, and an anti-slip pad is provided on the other side of the arc-shaped clamping plate 12 away from the pull rod 13, the protective pad being semi-arc shaped.

[0030] The ultrasound guide 2 is placed between two arc-shaped clamping plates 12 fixed by two support springs 11. Then, by pulling the lever 13, the ultrasound guide 2 can be passed through the arc-shaped clamping plates 12. At this time, the staff can release the pulling force of the lever 13, so that under the spring force of the support springs 11, the arc-shaped clamping plates 12 can be automatically reset, thereby tightly fitting the arc-shaped clamping plates 12 to the surface of the ultrasound guide 2 for clamping and fixing. This makes it easier for medical staff to operate the ultrasound guide 2 more stably. The ultrasound guide 2 provides real-time images to help doctors observe the position of the needle tip 5 and the surrounding structure to ensure the accuracy of injection. With the anti-slip pad on the surface of the lever 13, it can provide cushioning protection and increase friction when clamping the ultrasound guide 2, thereby clamping it firmly.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
