The puncture needle 200 is movably mounted on the needle holder 20 through the mounting seat 221, the puncture vacant site 30 through which the needle head of the puncture needle 200 penetrates is left between the ultrasonic probe 100 and the needle holder 20, the front and rear positions of the puncture needle 200 relative to the puncture vacant site 30 can be adjusted by moving the support seat 22, and the up and down positions of the puncture needle 200 relative to the puncture vacant site 30 can be adjusted by moving the mounting seat 221, so that the specific puncture site of the needle head of the puncture needle 200 can be adjusted. In this way, during puncturing, the auxiliary bracket is moved, the puncturing site is determined according to the guidance of the ultrasonic probe 100, after the puncturing site is determined, the auxiliary bracket is moved to the position right below or front side below the puncturing vacancy 30, then, the auxiliary bracket is stopped to be moved, at this time, the position of the puncture needle 200 is adjusted through the positions of the movable supporting seat 22 and the mounting seat 221, so that the needle head of the puncture needle is moved to a proper position capable of being accurately punctured into the puncturing site, and then the puncture needle 200 is pushed to perform puncturing operation.

In the process of puncture, the puncture site is guided and determined by using ultrasonic waves, and the position of the puncture needle 200 is adjusted by using the movable part of the auxiliary bracket, so that the needle head of the puncture needle can accurately puncture the puncture site, and the puncture failure or the damage of the puncture to surrounding tissues, organs and the like caused by the puncture needle 200 deviating from the puncture site can be effectively avoided; moreover, the ultrasonic probe 100 is fixed relative to the puncture site during the puncture process, so that the puncture site can be observed in real time by the ultrasonic probe 100 during and after the puncture process, and the situations such as accidental bleeding and the like during the puncture process can be found in time. The puncture accuracy improves, and puncture efficiency improves to can reduce the pain that the puncture brought for the patient, alleviate patient's psychological pressure.

In another embodiment of the present invention, as shown in fig. 1, 2 and 3, the base 21 includes a flat plate portion 211 and an extending portion 212, and the flat plate portion 211 has a smooth lower surface, so that it can better fit to the skin of the patient and move more smoothly. The support seat 22 is slidably mounted above the flat plate portion 211, the extension portion 212 extends from the front end of the flat plate portion 211 away from the flat plate portion 211, the probe holder 10 is mounted on the extension portion 212, specifically, the probe holder 10 may be detachably connected to the extension portion 212 or may be integrally formed with the extension portion 212, and the probe holder 10 is spaced from the front end of the flat plate portion 211 to form the puncture vacancy 30. When in use, the auxiliary bracket of the embodiment is placed on the body of a patient, the smooth lower surface of the flat plate part 211 is attached to the skin of the patient, then the ultrasonic probe 100 is opened, the auxiliary bracket is pushed to move under the guidance of the ultrasonic probe 100, the puncture site is confirmed, and the flat plate part 211 with a certain area is selected, so that the base 21 can stably support the supporting seat 22.

The ultrasound-guided lancing auxiliary stand of claim 1, wherein the base includes a flat plate portion having a smooth lower surface and an extension portion, the support base is slidably mounted over the flat plate portion, the extension portion extends away from the flat plate portion from a front end of the flat plate portion, the probe holder is mounted to the extension portion, the probe holder is spaced from the front end of the flat plate portion and forms the lancing void.

3. The ultrasonic guided puncture auxiliary stand according to claim 2, wherein the flat plate portion is provided with a sliding groove, the supporting seat is provided with a locking protrusion capable of being locked into the sliding groove in an adaptive manner, the sliding groove extends towards the puncture vacancy, and the supporting seat slides in the sliding groove through the locking protrusion so as to drive the puncture needle to move back and forth relative to the puncture vacancy.

4. The ultrasonic guided puncture auxiliary stand according to claim 2, wherein the flat plate portion is provided with a slide rail, the supporting seat is provided with a locking groove for locking the slide rail, the slide rail extends toward the puncture vacancy, and the supporting seat slides along the slide rail through the locking groove to drive the puncture needle to move back and forth relative to the puncture vacancy.

5. The ultrasound-guided lancing auxiliary stand according to claim 3, wherein said flat plate portion is further provided with a first graduated scale, said sliding groove extends along the length direction of said flat plate portion toward said lancing vacant site, and said first graduated scale is parallel to said sliding groove.

6. The ultrasonic guided puncture auxiliary stand according to claim 2, wherein the support base includes an adapter portion, a support portion, and a connecting portion, the adapter portion is slidably mounted on the flat plate portion, the connecting portion is supported by the support portion and connected to the adapter portion, the connecting portion is inclined toward the puncture vacant position with respect to the flat plate portion, and the mounting base is slidably disposed on the connecting portion and can move up and down with respect to the puncture vacant position along an inclined direction of the connecting portion.

7. The ultrasound guided lancing auxiliary stand according to claim 6, wherein the connecting portion is further provided with a second graduated scale, the connecting portion is inclined with respect to the flat plate portion along the length direction, the mounting seat slides along the length direction of the connecting portion, and the second graduated scale is parallel to the length direction of the connecting portion.

8. The ultrasound-guided puncture auxiliary stent of claim 6, wherein the connecting portion is provided with an elastic arm protruding toward the flat plate portion, and an end of the elastic arm away from the supporting portion can elastically abut against the flat plate portion, so as to limit the sliding of the adapting portion relative to the flat plate portion.

9. The ultrasonic guided puncture auxiliary stand according to any one of claims 2 to 8, wherein the probe holder is an elastic sleeve adapted to fit over the ultrasonic probe, an axis of the elastic sleeve is substantially perpendicular to a lower surface of the flat plate portion, and a bottom end of the elastic sleeve is disposed at a height higher than or equal to a height of the lower surface of the flat plate portion.

10. An ultrasonic guided puncture device, comprising an ultrasonic probe and a puncture needle, and further comprising the ultrasonic guided puncture auxiliary support according to any one of claims 1 to 9, wherein the ultrasonic probe is detachably mounted on the probe holder, and the puncture needle is detachably mounted on the mounting base.
