[0002] Pericardiocentesis is a procedure used to confirm the diagnosis and to relieve pericardial tamponade when there is fluid, blood or pus in the pericardial cavity. Existing pericardiocentesis mainly relies on CT scans. Doctors judge the location of the lesion based on CT images and their own medical experience. Because pericardiocentesis is risky, it should be performed or guided by an experienced physician and should be performed under ECG monitoring, which is safer. Because there is no fixed needle insertion path, manual puncture may lead to deviations in the judgment of the lesion location. The needle insertion path is unstable during manual puncture, which may cause the puncture position to shift and increase the operation time. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 , 3 , including an auxiliary measuring component 2, the auxiliary measuring component 2 is slidably sleeved with a puncture component 1, and a fixing component 3 is arranged on one side of the auxiliary measuring component 2.

[0023] See also Figure 2 The utility model provides a technical solution: a pericardial puncture positioning device for cardiology. The puncture assembly 1 includes a push-in connecting rod 7, the surface of which is slidably sleeved with an auxiliary adjusting slider 14, and both ends are fixedly connected with an injection fixing ring 8 and a connecting rod fixing ring 10, respectively. The middle of the auxiliary adjusting slider 14 is fixedly sleeved with an insertion syringe 6, and the connecting rod fixing ring 10 is slidably sleeved on the surface of the insertion syringe 6. One end of the insertion syringe 6 is fixedly connected with a needle entry port 4, and a positioning knob 5 is threadedly sleeved on the surface, and the other end of the insertion syringe 6 is fixedly sleeved with a syringe fixing ring 11. One side of the injection fixing ring 8 is movably connected with an injection fixing screw 9, and one side of the injection fixing ring 8 is protruding and has a gap, which is used to clamp needle tubes of different specifications. When the needle tube is pushed, the advancement is more stable under the action of the external clamping force. The auxiliary adjusting slider 14 is slidably sleeved on the auxiliary measuring assembly 2, and the syringe fixing ring 11 is rotatably sleeved on the inner cavity of the auxiliary measuring assembly 2 through the angle adjustment knob 12. The angle adjustment knob 12 can change the rotation direction according to the angle adjusted by the auxiliary adjusting slider 14, and the surface of the auxiliary measuring assembly 2 is provided with a scale.

[0024] See also Figure 4-5The fixing assembly 3 includes a fixing rod 15, and two fixing buckles 16 are arranged in the middle of the fixing rod 15, both of which are open designs and are fixed and clamped with screws. One side of the two fixing buckles 16 protrudes and is movably connected with a fixing screw 17, which is a butterfly screw for convenient manual operation. A fixing shaft 18 is rotatably sleeved at the bottom of the fixing rod 15, and fixing knobs 19 are arranged at both ends of the fixing shaft 18. The fixing shaft 18 is movably connected between the two fixing rods 15 and the fixing knobs 19. The size of the fixing rod 15 is consistent with the edge of the outer frame of the auxiliary measurement component 2, and can overlap with the frame of the auxiliary measurement component 2 when folded for easy storage.

[0025] See also Figure 2 The pushing connecting rod 7 and the piercing syringe 6 are parallel to each other, which is used to make the needle insertion position more accurate. The pushing direction of the needle tube is consistent with the direction of the needle insertion port. Under the pushing action of the pushing connecting rod 7, the needle insertion efficiency is higher. The auxiliary measuring component 2 is hollow inside and is provided with the piercing syringe 6. The auxiliary adjusting slider 14 is slidably sleeved on the external curved frame of the auxiliary measuring component 2. The external frame structure of the auxiliary measuring component 2 is a quarter circle. During the sliding process of the auxiliary adjusting slider 14, the exposed length of the piercing syringe 6 does not change with the movement trajectory of the auxiliary adjusting slider 14. The positioning knob 5 movably connected to the auxiliary adjusting slider 14 is tightened and fixed after determining the needle insertion angle. The inner core is placed inside the piercing syringe 6 to prevent skin or fat from clogging the needle.

[0026] During use, when the angle needs to be adjusted, first loosen the positioning knob 5 and the two angle adjustment knobs 12, so that the auxiliary adjustment slider 14 can slide freely on the auxiliary measurement component 2, and the syringe fixing ring 11 can rotate in the side inner cavity of the auxiliary measurement component 2, and the insertion syringe 6 can change the sleeve direction with the movement of the auxiliary adjustment slider 14. According to the angle to be adjusted, find the corresponding scale on the auxiliary measurement component 2, and after determining the position, tighten the needle port 4 to fix the position of the insertion syringe 6, and then tighten the two angle adjustment knobs 12 to fix the position of the needle tube at the end of the insertion syringe 6;

[0027] When the puncture needle needs to be clamped, first pull the push-in connecting rod 7 outward for a suitable length. At the same time, the connecting rod fixing ring 10 will slide on the surface of the insertion syringe 6 to increase the stability of the push-in connecting rod 7. Loosen the injection fixing screw 9 on the injection fixing ring 8, insert the needle tube into the middle of the injection fixing ring 8, pass through the inner cavity of the insertion syringe 6, and extend it out. Then, put the needle handle behind the needle port 4, and clamp the syringe in the inner cavity of the injection fixing ring 8, and tighten it with the injection fixing screw 9;

[0028] When fixation is required, first loosen the fixing knob 19, rotate the fixing rod 15 outward to a suitable fixing position, tighten the fixing knob 19 to fix the fixing rod 15, unscrew the fixing screws 17 on the two fixing buckles 16, make the fixing buckles 16 nested on the fixed object, and then tighten and fix them with the fixing screws 17.

[0029] When puncture is required, the needle tube clamped inside the injection fixing ring 8 undergoes translational movement in the inner cavity of the piercing syringe 6 under the action of the pushing connecting rod 7, pushing the puncture needle tip to the position on the back of the patient where puncture is required. After the puncture is completed, the pushing connecting rod 7 is pushed back to withdraw the needle tip from the back of the patient.
