It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0020] Example: A clinical ultrasonic puncture device, please see Figures 1 to 3, including an ultrasonic probe 1, a first limiting block 2, a first bracket 3, a first limiting frame 4, a placement block 5, a second limiting block 6, a second limiting frame 7, a scale plate 8, a syringe 9, an identification block 10, a second bracket 11, a pressing frame 12, a spring 13, a connecting frame 14, a connecting block 15, a guide rod 16 and a friction rod 17. The first limiting block 2 is connected to the front-to-back symmetrical center position of the lower outer side of the ultrasonic probe 1, the first bracket 3 is connected to both sides of the lower part of the ultrasonic probe 1, the first limiting frame 4 is horizontally clamped in the middle of the first bracket 3, and the first limiting frame 4 is located at the first Below a limiting block 2, the first bracket 3 is fixed to the first limiting frame 4 by a snap-fitting manner, so that the ultrasonic probe 1 can be separated from the placement block 5 for subsequent cleaning. The placement block 5 is snap-fitted to the right side of the first limiting frame 4, and a groove suitable for the movement of the puncture needle is opened at the bottom of the placement block 5. The top of the placement block 5 is connected to the second limiting block 6, and the second limiting frame 7 is connected to the right side of the placement block 5. The bottom of the second limiting frame 7 is opened with a groove suitable for the movement of the puncture needle. The right side of the second limiting frame 7 is connected to a scale plate 8, and the surface of the scale plate 8 is provided with scale lines. There is an arc-shaped slide groove, and the center of the scale plate 8 is hollowed out. A syringe 9 is slidably connected to the center of the scale plate 8. The front and rear sides of the middle of the syringe 9 are connected to identification blocks 10. An anti-slip groove is provided on the surface of the identification block 10 to increase the friction between the hand and the identification block 10 and play an anti-slip role. The identification block 10 slides with the corresponding arc-shaped slide groove on the scale plate 8. The right end of the syringe 9 is connected to a second bracket 11. A clamping frame 12 is symmetrically slidably connected to the lower side of the second bracket 11. The bottom of the clamping frame 12 is provided with an edge of the scale plate 8. The groove enables the clamping frame 12 to be fixed on the scale plate 8. The clamping frame 12 is connected to the second bracket 11 with a spring 13 to facilitate the resetting of the clamping frame 12. A connecting frame 14 is slidably connected to the upper side of the second bracket 11. The connecting frame 14 is connected to the tops of the two clamping frames 12, and the springs 13 are sleeved on the lower end of the connecting frame 14. A connecting block 15 is connected to the right side of the first limiting frame 4, and a guide rod 16 is connected to the upper left side of the connecting block 15. A friction rod 17 is slidably connected to the lower front side of the connecting block 15, and the friction rod 17 is connected to the placement block 5.
[0021] When it is necessary to use ultrasonic puncture equipment for body puncture, the medical staff first needs to determine the puncture body position and the puncture point, and then a series of disinfection and anesthesia work is performed. When the anesthesia takes effect, the medical staff can perform the body puncture operation and pass the puncture needle through the syringe 9. Since the bottom of the second limiting frame 7 is provided with a groove suitable for the movement of the puncture needle, the puncture needle can be suitable for puncture in the body at different angles and positions. The medical staff inserts the puncture needle into the patient's body through the groove at the bottom of the second limiting frame 7, and then the puncture position and situation in the body can be checked through the ultrasonic probe 1. According to the settings of the connecting block 15, the guide rod 16 and the friction rod 17, the puncture position can be easily adjusted. During the specific operation, the medical staff pulls the placement block 5, which will drive the second limiting frame 7, the scale plate 8, the syringe 9 and the puncture needle to move along the guide rod 16 to adjust the position of the puncture needle. By setting the scale plate 8, the angle of the puncture needle can be adjusted. The medical staff pulls the connecting frame 14 upwards, so that the pressing frame 12 moves upward and disengages from the scale plate 8, and the spring 13 is compressed by force. At this time, the syringe 9 is not fixed. The medical staff slides the identification block 10 on the scale plate 8 and adjusts the angle of the syringe 9 and the puncture needle according to the scale line on the scale plate 8. When the angle is adjusted to a suitable angle, the medical staff releases the connecting frame 14, so that the pressing frame 12 moves downward and resets under the action of the spring 13 to be stuck on the scale plate 8, and the syringe 9 is fixed to ensure the stability during the in vivo puncture process. Then the medical staff can continue the puncture operation on the patient. When the in vivo puncture operation is completed, the puncture needle is pulled out of the patient's body, and finally the patient is treated postoperatively. After the puncture device is used, according to the design of the first bracket 3 and the first limiting bracket 4, the first limiting bracket 4 is slid forward to separate it from the first bracket 3, so that the ultrasonic probe 1 can be separated from the placement block 5 on the right side, thereby facilitating the cleaning of the ultrasonic puncture device.

The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
