DETAILED DESCRIPTION

[0015] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0017] Embodiment 1, as Figure 1-5 As shown, an ultrasound-guided puncture bracket includes a probe 1, a fixed base 2 is provided at the bottom of the probe 1, a positioning buckle 3 is provided inside the fixed base 2, a probe positioning card 4 is provided on one side of the probe 1, the fixed base 2 is connected to a rotating shaft 5, a long-handled screw 12 is provided on one side of the rotating shaft 5, a puncture slide rail 6 is provided on one side of the long-handled screw 12, and a fixed slider 7 is provided on the puncture slide rail 6.

[0018] Probe positioning cards 4 are provided on both sides of the probe 1, and the probe positioning cards 4 are connected to the fixed base 2 through positioning buckles 3. The bottom of the fixed base 2 is improved to an inverted saddle shape. Since the skin on the surface of the human body is not horizontal, it can better fit the skin for fixing during puncture, which also facilitates puncture. A disposable silicone patch is provided at the bottom of the fixed base 2. During puncture, the disposable silicone patch is in direct contact with the skin. After puncture, the disposable silicone patch is directly torn off, which is not only clean and hygienic, but also eliminates the need to disinfect the probe for each puncture. The probe 1 completely blocks the ultrasonic sound waves through the detachable positioning strip 8, and the ultrasonic screen is displayed in black, thereby locating the central line of the ultrasonic emission surface. Then the probe circular fixing card 13 is put on the probe 1, and the probe circular fixing card 13 is fixed at both ends of the probe positioning card 4 and the detachable positioning strip 8. After the probe circular fixing card 13 is fixed, the detachable positioning strip 8 can be removed.

[0019] The fixed base 2 is connected to the rotating shaft 5, and the fixed base 2 is fixed to the rotating shaft 5 as a whole. A long-handled screw 12 is provided on one side of the rotating shaft 5, and a puncture slide rail 6 is provided on one side of the long-handled screw 12. The puncture slide rail 6 can realize multi-angle rotation through the rotating shaft 5 and the long-handled screw 12. At the same time, the long-handled screw 12 can also make the puncture slide rail 6 move left and right, and the puncture slide rail 6 is driven to move slightly by rotating the long-handled screw 12, so that the fixed slider 7 and the disposable puncture needle fixing clamp 10 on the puncture slide rail 6 can be overlapped with the projection line of the laser positioning light 9. A dovetail-shaped protrusion is provided on the puncture slide rail 6, and the fixed slider 7 has a corresponding dovetail groove, which can ensure that the fixed slider 7 does not rotate on the puncture slide rail 6, thereby ensuring stability during the puncture process. The design of the fixed slider 7 cooperates with the dovetail-shaped protrusion, so that the fixed slider 7 can slide smoothly on the puncture slide rail 6 and ensure the stable fixation of the puncture device.

[0020] The disposable puncture needle fixing clamp 10 is a disposable item and can be disposed harmlessly after puncture. The disposable puncture needle fixing clamp 10 is provided with a needle-shaped groove 11, through which the puncture needle can be fixed on the fixed slider 7. The needle-shaped groove 11 has different models and specifications, which can adapt to puncture needles of different sizes, thereby increasing practicality.

[0021] A laser positioning lamp 9 is provided on one side of the positioning buckle 3. The laser positioning lamp 9 is installed at the center of the fixed base 2. The laser positioning lamp 9 can emit a laser line to help puncture positioning. If the biopsy needle and the laser line are not in a straight line, the long-handled screw 12 can be moved to adjust so that the puncture needle can coincide with the laser line, thereby ensuring that the puncture needle is always within the image range of the probe 1. After the puncture needle is adjusted to coincide with the laser line, tighten the long-handled screw 12. The puncture needle will no longer move left and right, and can only change the puncture angle up and down.

[0022] Example 2, a method for using an ultrasound-guided puncture stent as shown in Example 1, comprising the following steps: 1) Inventory of items: Count the equipment before use and stick a disposable sterile non-slip silicone sticker on the fixed base 2; 2) Preparation: Install the detachable positioning strip 8 on the front center line of the probe 1. At this time, the detachable positioning strip 8 completely blocks the ultrasonic wave of the probe 1, thereby determining the center line position of the ultrasonic emission surface of the probe 1. At this time, put on the probe circular fixing card 13, so that the probe positioning cards 4 at both ends of the probe circular fixing card 13 are completely aligned with the two ends of the detachable positioning strip 8. At this time, fix the probe circular fixing card 13 and remove the detachable positioning strip 8. In this way, the positioning of the two ends of the probe circular fixing card 13 is completed, and the connection line of the probe positioning cards 4 on both sides of the probe 1 is exactly consistent with the center line of the probe 1. The probe circular fixing card 13 and the detachable positioning strip 8 can adapt to various types of probes 1, thereby increasing their practicality; 3) Fix the probe 1: Connect the circular probe fixing card 13 to the fixing base 2. In this way, the probe 1 and the fixing base 2 become a whole. At this time, the connection line of the probe positioning cards 4 on both sides of the probe 1 is in a straight line with the laser positioning lamp 9, thereby ensuring that the light emitted by the laser positioning lamp 9 is in a straight line with the center of the ultrasonic emission surface of the probe 1; 4) Start the laser: Start the laser positioning lamp 9 on the fixed base so that the light of the laser positioning lamp 9 and the center of the probe 1 are always in a straight line. Through the indication of the laser positioning lamp 9, it can be confirmed that the center position of the puncture device and the probe 1 coincide with each other; 5) Adjust the puncture slide rail 6: adjust the puncture slide rail 6 through the long-handled screw 12 so that the puncture slide rail 6 can move left and right on the fixed base 2, ensure that the central axis of the puncture needle on the puncture slide rail 6 coincides with the light emitted by the laser positioning lamp 9, and then fix the long-handled screw 12 so that the puncture needle will not move left and right.

[0023] 6) Install the fixed slider 9: Install the fixed slider 9 and the puncture needle onto the puncture slide rail 8, and adjust the rotation angle of the puncture slide rail 8 left and right so that the puncture needle and the light emitted by the laser positioning lamp 9 coincide with each other; 7) Start puncture: After confirming that all positions and angles are adjusted correctly, the doctor can start the puncture operation. The doctor gradually advances the puncture needle along the guidance of the puncture rail 6, and observes the progress of the puncture needle through real-time ultrasound guidance to ensure that the puncture needle accurately reaches the target lesion area; 8) Puncture monitoring: During the puncture process, observe the ultrasound screen. As long as the puncture needle enters along the laser line, it can be visualized on the screen. The center of probe 1 is aligned with the puncture lesion, and the puncture needle and the laser line on the outside overlap, and the puncture needle can be seen on the ultrasound screen entering the puncture lesion; 9) End the puncture; 10) Equipment Reorganization: After step 9) is completed, remove the probe 1 and reorganize other equipment.

[0024] Step 3) The probe positioning card 4 is connected to the fixed base 2 by using the probe circular fixing card 13 and the positioning buckles 3 at both ends for fixing.

[0025] The present invention provides an ultrasound-guided puncture stent, which achieves high accuracy and stability of the puncture operation by optimizing the fixation of the probe 1, laser positioning and adjustment of the puncture device. The system has a wide range of application prospects in medical diagnosis and treatment, and can significantly improve the effect of the puncture operation.
