Description

Technical Field

[0001] The utility model belongs to the technical field of puncture, and in particular relates to a cardiology puncture auxiliary positioning device. Background Art

[0002] A puncture, a common medical term, involves inserting a needle into a body cavity to extract secretions for testing, inject gas or contrast agent for imaging, or inject medication. The purpose of a puncture is to draw blood for testing, transfuse blood or fluids, and insert a catheter for angiography. Cardiology punctures can be used to detect various heart conditions, including pericardial effusion, heart failure, valvular heart disease, cardiac tumors, and cardiac thrombosis.

[0003] The existing puncture operation generally requires the doctor to hold the puncture needle, determine the puncture point before puncture, and perform the puncture operation. Manual puncture requires a high level of proficiency of the doctor. Even if the puncture point is determined, the puncture may fail due to hand shaking or other conditions. For this reason, we propose a device that can assist in puncture needle positioning. The device can adjust the position of the puncture needle and perform puncture at the determined puncture point, thereby improving the success rate of puncture. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example: Figure 1 As shown, a cardiology puncture auxiliary positioning device includes a support frame 10 for supporting the upper part of the patient's chest cavity, an adjustment device 30 for adjusting the puncture needle 305 is also provided on the top of the support frame 10, and a driving device 40 is further provided at the rear end of the adjustment device 30 to enable the adjustment device 30 to rotate;

[0036] The width of the support frame 10 should be greater than the patient's chest width. The puncture point needs to be located before puncture. Figure 1 The support frame 10 can be adjusted in angle around the Z axis. After the position of the support frame 10 is determined, a suction cup 50 is provided at the bottom end of the support frame 10 for positioning the support frame 10. The suction cup 50 can be a vacuum suction cup, and the suction cup 50 is threadedly connected to the support frame 10, so it can be easily removed when not in use.

[0037] like Figure 1As shown, a rotating member is further provided at the bottom end of the support frame 10 to help the support frame 10 rotate back and forth. The rotating member includes a connecting seat 20. A rotating shaft 20B is further provided between the connecting seat 20 and the support frame 10. In order to ensure the positioning of the support frame 10, the rotating shaft 20B is also transitionally matched with the support frame 10 to achieve the purpose of allowing the support frame 10 to hover at any time. Therefore, the support frame 10 is rotated back and forth to near the puncture point;

[0038] like Figure 1 As shown, a pad 20A is glued to the bottom outer wall of the connecting base 20;

[0039] like Figure 1-2 As shown, the adjusting device 30 should also include a rotating member 301, and a connecting shaft 303 is fixedly sleeved on the rear end of the rotating member 301. The connecting shaft 303 passes through the support frame 10 and is connected to the driving device 40. A housing 304 is integrally formed at the bottom end of the rotating member 301, and a puncture needle 305 is provided in the housing 304.

[0040] like Figure 3 As shown, the driving device 40 mainly includes a protective shell 401, which is fixedly arranged on the rear outer wall of the support frame 10. A worm gear 402 and a worm 403 that mesh with each other are also provided in the protective shell 401. The connecting shaft 303 passes through the worm gear 402 and is fixedly sleeved therewith. The worm 403 serves as an active component, one end of which passes through the protective shell 401 and extends to the outside of the shell for easy adjustment by the user. A handle for twisting is also provided on one end of the worm 403 outside the shell, which is used to adjust the position of the puncture needle 305. When the worm 403 is rotated, the worm gear 402 meshing with the worm gear 402 rotates, which drives the connecting shaft 303 inside the worm gear 402 to rotate, and the rotating member 301 at one end of the connecting shaft 303 rotates. Because the puncture needle 305 is installed in the housing 304 at the bottom end of the rotating member 301, the puncture needle 305 is driven to rotate together. To this end, the angle of the puncture needle 305 is adjusted by the driving device 40, so that a certain angle is formed between the puncture needle 305 and the puncture point, which is more conducive to puncture.

[0041] After the position and angle of the puncture needle 305 are determined, the final puncture work can be carried out. Figure 4The positional relationship between the puncture needle 305 and the housing 304 is shown. A lifting structure is further provided in the housing 304. The lifting structure includes an adjusting bolt 302 threadedly connected to the inner side of the rotating member 301. The bottom end of the adjusting bolt 302 corresponds exactly to the top end of the puncture needle 305. A spring 306 is further provided in the inner cavity of the housing 304. The top end of the spring 306 abuts against the bottom end of the needle handle of the puncture needle 305. When in use, the adjusting bolt 302 is rotated to puncture the puncture needle 305 toward the patient's puncture point. After the puncture is completed, the adjusting bolt 302 is reset. Under the rebound of the compression force of the spring 306, the puncture needle 305 is also reset. The tumor tissue obtained by the puncture needle 305 is then sent to a pathologist for cytological and histological examinations.

[0042] After the puncture is completed, the device is reset and disinfected, and the puncture needle 305 is taken out. When the puncture is performed next time, a new puncture device is used to avoid problems such as infection.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
