[0022] The present invention will now be described in further detail:

[0023] like Figures 1 to 5 As shown, this utility model provides a cardiology puncture device, including a fixed clamp 1. A support assembly 2 is fixedly connected to the top of the fixed clamp 1. Two clamping assemblies 3 are fixedly installed on the upper front side of the support assembly 2. The support assembly 2 includes a limiting sleeve 21 fixedly connected to the top of the fixed clamp 1. A rotating rod 22 is movably engaged inside the limiting sleeve 21. A limiting gear 23 located inside the limiting sleeve 21 is fixedly connected to the outside of the rotating rod 22. The limiting gear 23 located inside the limiting sleeve 21 is movably engaged inside the limiting sleeve 21. 3. A retaining plate 24 on the side, a spring 25 is movably sleeved on the outside of the retaining plate 24, an adjusting sleeve 26 is movably sleeved on the outside of the rotating rod 22, a fixing sleeve 27 is fixedly connected to the outside of the adjusting sleeve 26, a retaining block 28 is movably locked inside the fixing sleeve 27, a slot corresponding to the retaining block 28 is opened on the outside of the rotating rod 22, a spring 29 is movably sleeved on the outside of the retaining block 28, a damping groove 210 is opened on the top of the adjusting sleeve 26, and an extension rod 211 is movably installed inside the damping groove 210.

[0024] The single fixed clamp 1 facilitates fixation and improves portability. By pulling the clamp 24 outward to disengage it from the side of the limiting gear 23, the rotating rod 22 can rotate within the limiting sleeve 21. By pulling the adjusting sleeve 26 outward to disengage it from the slot on the side of the rotating rod 22, the height of the adjusting sleeve 26 outside the rotating rod 22 can be adjusted. The extension rod 211 can slide along the damping groove 210 for lateral adjustment, thereby improving the flexibility of needle position adjustment and enhancing ease of use.

[0025] like Figure 5 As shown, the clamping assembly 3 includes a clamping sleeve 31, a groove 32 is provided inside the clamping sleeve 31, a guide groove 33 is provided inside the clamping sleeve 31 that communicates with the groove 32, a movable block 34 is movably engaged inside the guide groove 33, a spring 35 located in the guide groove 33 is movably sleeved outside the movable block 34, and a pull handle 36 is fixedly connected to the outside of the movable block 34.

[0026] Pulling the handle 36 outward can move the movable block 34 outward to compress the spring 35. By inserting the needle tube into the slot 32 and releasing the handle 36, the spring 35 pushes the movable block 34 inward along the guide groove 33 to clamp the tube. Conversely, the tube can be disassembled from the slot 32, thus facilitating the disassembly and maintenance of the needle tube.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, spring 1 25 and spring 2 29 are respectively movably engaged inside the limiting sleeve 21 and the fixing sleeve 27.

[0028] Handwheels are fixedly connected to the outer sides of both the card plate 24 and the card block 28.

[0029] Spring 25 and spring 29 are respectively locked inside the limiting sleeve 21 and the fixing sleeve 27. When the locking plate 24 and the locking block 28 are pulled, spring 25 and spring 29 located inside the limiting sleeve 21 and the fixing sleeve 27 can be compressed. The elastic force of spring 25 and spring 29 pushes the locking plate 24 and the locking block 28 to reset and fix, which is convenient for operation.

[0030] like Figure 4 As shown, the adjusting sleeve 26 is L-shaped, and two clamping components 3 are fixedly installed on the front side of the adjusting sleeve 26 and the extension rod 211, respectively.

[0031] The position of the clamping assembly 3 can be adjusted by sliding along the damping groove 210 via the extension rod 211 through the "L"-shaped adjusting sleeve 26, thereby facilitating the adjustment of the needle tube position.

[0032] like Figure 5As shown, the inner side of the movable block 34 is arranged in an arc shape corresponding to the slot 32.

[0033] The inner side of the movable block 34 is arranged in an arc shape corresponding to the slot 32, which makes it easy to lock the needle tube in it for fastening, and also makes it easy to disassemble.

[0034] like Figure 1 As shown, the locking block 28 penetrates the adjusting sleeve 26 and is movably engaged in the slot on the outside of the rotating rod 22.

[0035] The height is adjusted and limited by inserting the locking block 28 through the adjusting sleeve 26 into the slot on the side of the rotating rod 22. The slot is located outside the rotating rod 22 and is set longitudinally at equal intervals to facilitate multi-position adjustment.

[0036] like Figure 2 As shown, the bottom of the fixed clamping plate 1 is threadedly connected to a threaded rod 4, and the top of the threaded rod 4 is movably mounted with a clamping plate 5 located inside the fixed clamping plate 1.

[0037] By positioning the fixation splint 1 close to the patient's puncture site, clamping it onto one side of the bed, and rotating the threaded rod 4, the clamping plate 5 located inside the fixation splint 1 is moved upward and clamped onto one side of the bed, thus facilitating fixation on the side of the bed to provide support.

[0038] The working principle of this cardiology puncture device will be explained in detail below.

[0039] like Figures 1 to 5 As shown, by positioning the fixed clamp 1 close to the patient's puncture site, it is clamped onto one side of the bed. Rotating the threaded rod 4 causes the clamping plate 5 located inside the fixed clamp 1 to move upward and clamp onto one side of the bed. Then, by pulling the handwheel on the outer side of the clamping plate 24 outward, the clamping plate 24 moves outward and moves out from the side of the limiting gear 23, releasing the limiting gear 23. During this process, the spring 25 is compressed, and the limiting gear 23 is rotated along the limiting sleeve 21 by the rotating rod 22 for adjustment. After the clamping plate 24 is released, the spring force of the spring 25 pushes the clamping plate 24 to clamp onto the side of the limiting gear 23 for limiting. By pulling the handwheel on the outer side of the clamping block 28 outward, the clamping plate 5 located inside the fixed clamp 1 is pressed against the bed. Spring 29 on the inner side of the fixed sleeve 27 causes the locking block 28 to disengage from the slot on the outer side of the rotating rod 22 and slide up and down along the vertically equidistant slot to adjust the height of the adjusting sleeve rod 26. The locking block 28 is fixed by being inserted into the slot. The puncture position can be adjusted by moving the extension rod 211 along the damping slide groove 210. Pulling the handle 36 outward can move the movable block 34 outward to squeeze the spring 35. By inserting the needle tube into the inner side of the slot 32 and releasing the handle 36, the spring 35 pushes the movable block 34 inward along the guide groove 33 to clamp the tube. Conversely, the tube can be disassembled from the slot 32 and punctured and drained through the needle.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
