[0042] This embodiment provides an ultrasonic puncture fixation device, such as Figures 1 to 16 As shown, the probe mounting seat 11 is provided, and the probe mounting seat 11 is used to install the ultrasonic probe 2. The probe mounting seat 11 includes a detection end for facing the skin of the operation area when in use, and a detection port 16 is provided on the detection end. The ultrasonic probe 2 mounted on the probe mounting seat 11 can be exposed through the detection port 16 to transmit ultrasonic waves to the operation area. The probe mounting seat 11 is provided with a skin sticking mechanism and a puncture needle seat installation mechanism. The skin sticking mechanism is used to stick to the skin to fix the probe mounting seat 11 at the operation area, and the puncture needle seat installation mechanism is used to install the puncture needle seat 4.

[0043] Here’s how to use it:

[0044] S1. Apply an appropriate amount of sterile coupling agent on the ultrasonic probe 2, wrap the probe with a disposable sterile probe protective cover, and tie the disposable sterile probe protective cover tightly;

[0045] S2, placing the packaged ultrasound probe 2 into the puncture frame;

[0046] S3, aligning the detection port 16 of the probe mounting base 11 with the skin of the operation area, starting the ultrasound probe 2, and moving the probe mounting base 11 to perform ultrasound positioning before puncture;

[0047] S4. After determining the puncture position, install the disposable puncture needle seat 4 at a suitable angle, hold the probe mounting seat 11, and adhere the skin adhesive mechanism to the skin to fix the probe mounting seat 11 and the ultrasonic probe 2;

[0048] S5, the puncture needle 5 is inserted along the guide hole 43 of the puncture needle seat 4;

[0049] S6, the operation is completed, the puncture needle 5 is withdrawn, and a cotton swab is used for local pressing;

[0050] S7. After the standard procedure of compression and hemostasis, the skin adhesive mechanism is removed, the probe mounting seat 11 is removed, the operation area is cleaned and the corresponding bandage and covering are performed;

[0051] S8. Remove the ultrasound probe 2 and the puncture needle holder 4, remove the protective cover of the ultrasound probe 2, and then have the assistant clean the ultrasound probe 2 to prepare for the next interventional operation.

[0052] The specific operation process and operation sequence of the above usage method are for reference only and are not limited to such operation.

[0053] In one embodiment, if Figures 1 to 16 As shown, the probe mounting base 11 also includes two mounting ends, and the two mounting ends are respectively arranged on both sides of the detection end. Both mounting ends are provided with a skin sticking mechanism, and the skin sticking mechanism includes a movable adhesive plate 12, and the movable adhesive plate 12 is in a hinged relationship with the mounting end. The movable adhesive plate 12 has a bonding plate surface, and the bonding plate surface is used to fit with the skin. The bonding plate surface is provided with a skin-friendly adhesive 17 for bonding with the skin. The hinge axis of the movable adhesive plate 12 and the mounting end is parallel to the bonding plate surface, so that the movable adhesive plate 12 can be rotated toward the skin or away from the skin. The number of movable adhesive plates 12 is not limited and is set according to actual needs. For example, one movable adhesive plate 12 can be provided on each of the two mounting ends, or multiple movable adhesive plates 12 can be provided on each. Preferably, the movable adhesive plates 12 on the two mounting ends are symmetrically arranged. When using, first peel off the protective paper on the skin-friendly adhesive sticker 17, put the skin-friendly adhesive sticker 17 of the movable adhesive plate 12 in contact with the skin, and then gently press the movable adhesive plate 12. When removing, the movable adhesive plate 12 also needs to be gently lifted up.

[0054] In one embodiment, if Figures 1 to 16 As shown, both mounting ends of the probe mounting seat 11 are provided with buckles 121, and the movable adhesive plate 12 is provided with a hinge shaft 122. By snapping the hinge shaft 122 into the buckle 121, the movable adhesive plate 12 and the probe mounting seat 11 can be hinged.

[0055] In one embodiment, if Figures 1 to 16As shown, the probe mounting seat 11 also includes a plug-in end, which is located between the two mounting ends. The plug-in end is provided with a T-shaped slot 15, which is mainly composed of a mutually perpendicular transverse slot section 151 and a vertical slot section 152, and the end of the vertical slot section 152 away from the transverse slot section 151 is connected to the detection port 16. The ultrasonic probe 2 is installed in the T-shaped plug 21, which is mainly composed of a mutually perpendicular transverse head section 211 and a vertical head section 212, the transverse head section 211 is used to be plugged into the transverse slot section 151, and the vertical head section 212 is used to be plugged into the vertical slot section 152. The end of the vertical head section 212 away from the transverse head section 211 is provided with an installation port 213, and the ultrasonic probe 2 can be plugged into the installation port 213 through the installation port 213. A cable groove (not shown in the figure) should be reserved at the installation port 213 to facilitate the cable 22 to be inserted into the vertical head section 212. The T-shaped slot 15 and the T-shaped plug 21 form a tenon locking method. Preferably, a gap is reserved between the mounting port 213 and the ultrasonic probe 2 for using a sterile probe protective cover for the ultrasonic probe 2. The relative fixation of the two is achieved by relying on the friction between the ultrasonic probe 2 + protective cover and the mounting port 213. The gap is about 0.5 mm, which can avoid the ultrasonic probe 2 and the mounting port 213 being too tightly connected, resulting in the inability to protect the sterile environment.

[0056] In one embodiment, if Figures 1 to 16 As shown, the probe mounting seat 11 also includes an opposite side end, which is located on the opposite side of the plug-in end. The puncture needle seat mounting mechanism includes an in-plane puncture needle seat socket 13 and an out-of-plane puncture needle seat socket 14, and the in-plane puncture needle seat socket 13 and the out-of-plane puncture needle seat socket 14 both include plug-in blocks, and both sides of the plug-in blocks are provided with hemispherical recesses 19. The plug-in block is used for plugging in the plug-in groove 41 of the puncture needle seat 4. The hemispherical recess 19 is used for the hemispherical protrusion 42 in the plug-in groove 41 of the puncture needle seat 4 to be snapped in and positioned. The in-plane puncture needle seat socket 13 is mounted on the opposite side end, and the out-of-plane puncture needle seat socket 14 is mounted on one of the mounting ends. The movable adhesive plate 12 on the mounting end on which the out-of-plane puncture needle seat socket 14 is mounted has a through-port 18 for the puncture needle 5 to pass through, and it is best to also allow the out-of-plane puncture needle seat socket 14 to pass through. Of course, the through opening 18 can also be provided on the movable adhesive plate 12 on the other mounting end, which does not mean that it cannot be provided, but it is just not used.
