Description

Technical Field

[0001] The utility model relates to the technical field of puncture devices, in particular to an adjustable positioning puncture device. Background Art

[0002] Cardiology is a branch of internal medicine that specializes in diseases of the heart and circulatory system. A positioning puncture device is an instrument used to accurately locate and puncture the target site during surgery. A cardiology clinical positioning puncture device refers to an instrument used in the clinical practice of cardiology to accurately locate and precisely puncture the target site of the heart or blood vessels.

[0003] Some existing puncture devices are set as integrated devices, which makes it difficult to adjust the size of the device. When fixing it on beds of different lengths, different types of devices need to be used, which is less practical. In addition, when adjusting the horizontal position of the puncture needle with this type of puncture device, it is necessary to first release the fixation between the device and the bed, and then move the entire device to a suitable position, which is more troublesome.

[0004] Therefore, those skilled in the art provide an adjustable positioning puncture device to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an adjustable positioning puncture device. By setting two fixing mechanisms and a supporting mechanism, it is more convenient to change the horizontal position of the adjustment mechanism. By setting a first slider, two L-shaped plates and a connecting plate, the puncture device can be adjusted according to the size of the bed, thereby improving the practicability of the device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable positioning puncture device, comprising two fixing mechanisms, a supporting mechanism and an adjusting mechanism, the two adjusting mechanisms comprising two fixing blocks, two first screw rods and two first sliders, the two fixing blocks are fixedly provided with fixing plates at the upper positions on both sides of the front and rear end surfaces, and a plurality of fixing plates are rotatably provided with rotating plates between the end surfaces of one side opposite to each other;

[0007] The support mechanism includes two L-shaped plates, a connecting plate, two sliding grooves, two hand-pull plates, two rotating blocks and two rings. A reset spring is fixedly arranged between the two hand-pull plates and the two sliding grooves. A plurality of pointed blocks are fixedly arranged on the opposite end surfaces of the two hand-pull plates. A second screw rod is rotatably arranged between the inner walls on both sides of the connecting plate. Extension plates are rotatably arranged on the end surfaces on both sides of the second screw rod.

[0008] The adjustment mechanism includes a second slider, a mouth-shaped plate and two U-shaped plates. A third screw rod is rotatably arranged on the upper end surface of the mouth-shaped plate. A third slider is threadedly sleeved on the middle position of the outer end surface of the third screw rod. A second bolt is threadedly arranged on one side end surface of the third slider.

[0009] Through the above technical scheme, by manually rotating the first screw rod, the first screw rod drives the first slider to move, so that the first slider is abutted against the edge of the bed, and then the two first bolts are rotated to release the fixation of the two L-shaped plates to the connecting plate, and then one L-shaped plate is held to move, and when it moves to a suitable position, the other first slider is abutted against the end face of the bed, and finally the two first bolts are rotated again. At this time, the four rotating plates are rotated from a vertical state to a horizontal state, and then the hand-pull plate is pulled. After pulling out a certain distance, the rotating block is manually rotated to fix the hand-pull plate. After the two hand-pull plates are fixed, the L-shaped plate is held to move, and when it moves to a suitable position, the two rotating plates are turned back. Finally, the horizontal position of the puncture needle can be adjusted by rotating the extension plate, and the vertical position of the puncture needle can be adjusted by rotating the third screw rod.

[0010] Furthermore, the two first screw rods respectively penetrate the lower end surfaces of the two fixed blocks for rotation, and the two first sliding blocks are respectively threadedly sleeved on the upper sides of the outer end surfaces of the two first screw rods;

[0011] According to the technical solution, by rotating the first screw rod, the first screw rod drives the first slider to move, and the first slider abuts against the edge of the bed, thereby fixing the puncture device and the bed together.

[0012] Furthermore, the two L-shaped plates are slidably connected to the two fixing blocks respectively, and the two L-shaped plates are fixedly connected to the connecting plate by first bolts;

[0013] Through the above technical solution, by rotating the two first bolts, the two L-shaped plates are not fixed to the connecting plate. When the fixing block is pulled, the L-shaped plates are moved together and slide on the end surface of the connecting plate.

[0014] Furthermore, the two sliding grooves are respectively opened on the lower side of the end faces of the two L-shaped plates on one side opposite to each other, the two hand-pull plates are respectively slidably arranged on the inner walls of the two sliding grooves, and the two rotating blocks are respectively rotatably arranged on the lower side of the end faces of the two L-shaped plates on the opposite side;

[0015] Through the above technical solution, after the hand-pulled plate is pulled for a certain distance, the rotating block is rotated, and the hand-pulled plate is fixed by the abutment between the rotating block and the hand-pulled plate.

[0016] Furthermore, the two circular rings are respectively fixedly arranged on the upper sides of the end surfaces on the opposite sides of the two L-shaped plates, and the two extension plates are respectively rotatably connected to the two circular rings;

[0017] Through the above technical solution, when the L-shaped plate is pulled, the L-shaped plate drives the extension plate to move through the circular ring, and by rotating the extension plate, the second screw rod can be driven to rotate together.

[0018] Furthermore, the second slider is threadedly sleeved at the middle position of the outer end surface of the second screw rod, and the mouth-shaped plate is fixedly connected to the second slider through two U-shaped plates;

[0019] Through the above technical solution, the second sliding block is connected to the mouth-shaped plate through the U-shaped plate, so that when the third screw rod is rotated, there will be no end surface blocking the rotation of the third screw rod.

[0020] The utility model has the following beneficial effects:

[0021] 1. The utility model proposes an adjustable positioning puncture device, which fixes an L-shaped plate by manually rotating the first screw rod to make the first slider abut against the edge of the bed. At this time, the two first bolts are rotated, and then the other L-shaped plate is moved to move the other first slider to the upper end of the edge of the bed, and then the other first screw rod is rotated, and finally the two first bolts are turned back. By setting the first slider, the two L-shaped plates and the connecting plate, the puncture device can be adjusted according to the size of the bed, thereby improving the practicality of the device.

[0022] 2. The utility model proposes an adjustable positioning puncture device, which manually rotates four rotating plates to a horizontal position, and then pulls the hand-pull plate to one side. After pulling a certain distance, the rotating block is manually rotated and pushed into the through hole of the hand-pull plate to fix the hand-pull plate. Then the same operation is performed on the other hand-pull plate. At this time, the L-shaped plate can be held to move. After moving to a suitable position, the two rotating blocks are rotated back to the original position, and the two hand-pull plates are pulled back to the original position by the rebound force of the reset spring. By setting two fixing mechanisms and a supporting mechanism, it is more convenient to change the horizontal position of the adjustment mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
