[0031] Example: Figure 1-5 As shown, this utility model provides a technical solution, an ultrasound-guided puncture auxiliary device, including a fixing groove plate 1, and an ultrasound component 2 installed on the inner side of the fixing groove plate 1;

[0032] The ultrasonic component 2 includes a snap-fit ​​groove 201, an ultrasonic probe 202, a data transmission line 203, a fixing film 204, an indicator arrow 205, a slide rail 206, a scale line 207, a sliding groove 208, a sliding groove plate 209, a scale groove 210, a rotating seat 211, a needle groove tube 212, an insertion groove 213, a 45-degree limiting rod 214, a 15-degree limiting block 215, a dividing line groove 216, and a movable through hole 217.

[0033] The inner side of the fixed slot plate 1 is provided with a snap-fit ​​groove 201, and an ultrasonic probe 202 is slidably snapped into the inner side of the snap-fit ​​groove 201. The top of the ultrasonic probe 202 is connected to a data transmission line 203.

[0034] A rotating seat 211 is welded to the top of the sliding groove plate 209, and a needle groove tube 212 is rotatably installed on the inner side of the rotating seat 211.

[0035] The inner side of the sliding groove plate 209 is provided with an insertion groove 213, the top of the rotating seat 211 is equipped with a 45-degree limiting rod 214, and the top side of the sliding groove plate 209 is equipped with a 15-degree limiting block 215.

[0036] For ease of transmission, a slot 201 is formed through the inner side of the fixed slot plate 1, and the output end of the data transmission line 203 is electrically connected to the input end of the external display and fixes the ultrasonic probe.

[0037] In order to facilitate the fixation of the ultrasonic probe 202, a fixing film 204 is connected to the top of the fixing slot plate 1 to facilitate the adhesion of the ultrasonic probe 202.

[0038] An indicator arrow 205 is provided at the bottom center of the front of the fixed slot plate 1. A slide rail 206 is installed at the bottom edge of the front of the fixed slot plate 1. The indicator arrow 205 is located at the bottom edge of the center of the front of the fixed slot plate 1. The fixed slot plate 1 and the slide rail 206 are perpendicular to each other to ensure accuracy.

[0039] The top of the slide rail 206 is provided with a scale line 207, the smallest scale unit of which is one millimeter, which can ensure accuracy.

[0040] The slide rail 206 has a sliding groove 208 on its side end face. A sliding groove plate 209 is slidably sleeved on the inner side of the sliding groove 208. A scale groove 210 is provided on both sides of the top of the sliding groove plate 209 at the position corresponding to the scale line 207. There are two scale grooves 210, which are symmetrically provided on the top edge of the sliding groove plate 209, so as to facilitate the adjustment of different angles.

[0041] To facilitate the removal of the puncture probe, the needle groove tube 212 is provided with dividing grooves 216 on both sides. The dividing grooves 216 divide the needle groove tube 212 into two parts, and the two parts of the needle groove tube 212 are connected by spot fusion.

[0042] To facilitate the movement of the puncture probe, a movable through-hole slit 217 is provided at the bottom of the 15-degree limiting block 215. The movable through-hole slit 217 divides the sliding groove plate 209 into two parts, and the two parts of the sliding groove plate 209 are connected by spot fusion.

[0043] The inner diameter of the movable through-hole slit 217 is larger than the outer diameter of the puncture probe, which facilitates the movement of the movable puncture probe.

[0044] The working principle and usage process of this utility model are as follows: First, before using the puncture needle, the medical staff disinfects the skin surface of the arm to be punctured, and after disinfection, the coupling agent is evenly applied to the skin surface at the location where the puncture needle needs to reach. Then, the operator places the fixing plate 1 on the skin surface where the coupling agent has been applied, and presses the fixing plate 1 to make it fit the skin surface. At this time, sufficient coupling agent will remain on the inner side of the fixing plate 1.

[0045] Medical staff can insert the ultrasound probe 202 into the inner side of the fixing plate 1, and then press the ultrasound probe 202 down along the snap-fit ​​groove 201. Then the ultrasound probe 202 will come into contact with the coupling agent on the skin surface. Due to the presence of the fixing plate 1, the ultrasound probe 202 will be perpendicular to the skin surface. Then, the fixing plate 1 is moved continuously. At this time, the medical staff can observe the image transmitted back by the data transmission line 203 through the external monitor, so as to observe the lesion under the skin in real time. At this time, the position indicated by the indicator arrow 205 is the position of the subcutaneous artery. Then, the medical staff can determine the distance from the subcutaneous artery to the position of the ultrasound probe 202 through the monitor.

[0046] Next, the operator slides the sliding groove plate 209. When the reading on the scale groove 210 is equal to the distance from the subcutaneous artery to the ultrasound probe 202, the sliding stops. At this point, the distance from the subcutaneous artery to the ultrasound probe 202 is equal to the distance from the needle groove tube 212 to the ultrasound probe 202. Since the fixed groove plate 1 and the slide rail 206 are perpendicular, the subcutaneous artery, the observation point of the ultrasound probe 202, and the bottom of the needle groove tube 212 form the three vertices of an isosceles triangle. The puncture needle is then inserted through the needle groove tube 212, and the needle groove tube 212 is rotated to the 45-degree limiting rod 214 position. The puncture needle is the hypotenuse of this isosceles triangle. The puncture needle is then inserted into the skin through the insertion groove 213. As the insertion depth increases, the puncture needle can accurately reach the subcutaneous artery. Then, the medical staff can rotate the needle groove tube 212 to the 15-degree limiting block 215 and slowly push the puncture needle to accurately insert the needle tip into the artery. During the adjustment, the ultrasound probe 202 can be used to observe the subcutaneous area in real time, eliminating the need for medical staff to perform punctures based on experience. This not only improves the accuracy of the puncture needle operation but also saves puncture time, reduces patient discomfort, and further improves operational efficiency.

[0047] Secondly, the needle groove tube 212 has four specifications according to requirements, which are suitable for different product needles, and the through hole of the slide rail 206 is also changed according to the requirements of the needle groove tube 212, which requires it to be larger than the outer diameter of the needle tube.

[0048] After the operation is completed, crush the needle groove tube 212 and the 15-degree limiting block 215. Because of the presence of the dividing groove 216 and the moving through hole 217, the needle groove tube 212 and the sliding groove plate 209 are both equal to two parts. In this application, a fragile plastic material is selected, but the force needs to meet the degree of manual squeezing. After crushing the needle groove tube 212, the puncture probe is removed from the moving through hole 217, and the excess mechanism is removed to complete the positioning operation.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
