[0018] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.
[0019] According to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment proposes an ultrasonic guidance stent, which includes a fixed frame 1, a connecting rod 2 and a limiting rod 3. The two sides of the fixed frame 1 are symmetrically and fixedly connected with the connecting rod 2. The bottom end of the connecting rod 2 is fixedly connected with the limiting rod 3. The top of the limiting rod 3 is installed with an assembly block 4 through a rotating mechanism. A guiding mechanism is arranged inside the assembly block 4. An imaging device outside the fixed frame 1 is fixed on one side of the assembly block 4. When an ultrasonic puncture needle is inserted into the affected area of a patient through the guiding mechanism, and then the specific conditions inside the affected area are observed through the imaging device, it helps doctors observe and analyze the patient's condition. Moreover, the rotating mechanism can adjust the angle at which the ultrasonic puncture needle is inserted into the affected area, making it more flexible for doctors to use the ultrasonic puncture needle.
[0020] The guiding mechanism includes a sleeve rod 5, a guiding tube 6 and a fastening bolt 9. A guiding tube 6 is arranged inside the assembly block 4. The top end of the guiding tube 6 is fixedly connected with the sleeve rod 5. The fastening bolt 9 is threadedly connected inside the sleeve rod 5. The ultrasonic puncture needle is inserted into the inside of the sleeve rod 5, and it is communicated with the inside of the guiding tube 6. The ultrasonic puncture needle is inserted into the affected area along with the guiding tube 6. By screwing in or out the fastening bolt 9, the volume of the sleeve rod 5 is changed, so that the ultrasonic puncture needle fits against the inner wall of the sleeve rod 5 to limit the ultrasonic puncture needle.
[0021] The rotating mechanism includes an arc-shaped groove 7 and a first threaded rod 8. A clamping block 10 is arranged outside the assembly block 4. Sliding rods and a first threaded rod 8 are respectively fixedly connected to both sides of the clamping block 10. One end of the sliding rod penetrates through the arc-shaped groove 7 on one side of the limiting rod 3 and is fixedly connected with a stop piece. One end of the first threaded rod 8 penetrates through the arc-shaped groove 7 on the other side of the limiting rod 3 and is threadedly connected with a threaded sleeve. The clamping block 10 is connected to the arc-shaped groove 7 at the top of the limiting rod 3 through the sliding rod and the first threaded rod 8 respectively. The arc-shaped groove 7 and the stop piece cooperate to limit the rotation trajectory of the clamping block 10. When the clamping block 10 rotates to a suitable position, the threaded sleeve at one end of the first threaded rod 8 is tightened, and the threaded sleeve clamps the limiting rod 3 and the first threaded rod 8 to lock the position of the clamping block 10. The guiding mechanism is fixed on the clamping block 10 through the assembly block 4 to adjust the angle at which the ultrasonic puncture needle is inserted into the affected area.
[0022] A rectangular groove is provided on the inner side of the clamping block 10. The outer wall of the assembly block 4 is engaged with the inner wall of the rectangular groove. The clamping block 10 and the assembly block 4 are detachably connected by fixing bolts. The assembly block 4 is inserted into the clamping block 10 along the rectangular groove, and then the fixing bolts are screwed into both sides of the clamping block 10 to completely fix the assembly block 4 and the clamping block 10 together. At this time, the guiding mechanism is fixed at the top of the limiting rod 3. When it is necessary to release the connection, the fixing bolts are screwed out, and then the assembly block 4 is pulled out from the inside of the clamping block 10.
[0023] A spline 11 is fixedly connected to the outer side of the guiding tube 6. A spline groove 15 is provided inside the assembly block 4.
