Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a biopsy puncture device for nursing kidney patients. Background Art

[0002] Biopsy is a method used to identify tumors. It mainly uses a fine needle or puncture needle to remove cells or tissues, and then conducts pathological analysis. It is a method to determine whether the tissue is benign, malignant, or a specific tumor type before surgery. Renal biopsy requires the patient to lie in a prone position, and then insert the puncture needle from the back to obtain kidney tissue for pathological diagnosis. When inserting the puncture needle into the patient's kidney, it is necessary to determine the puncture site and keep the puncture needle stable.

[0003] Therefore, a biopsy puncture device has emerged, including a main frame, a clamping part and a pushing part arranged on the main frame. The clamping part includes two clamping blocks arranged on the main frame, and the end of the puncture needle is fixed by the clamping blocks, and the pushing part is fixed to the clamping blocks. When puncturing, the end of the puncture needle is fixed by the two clamping blocks, and the pushing part is started to drive the clamping blocks to move, thereby completing the puncture operation of the puncture needle; this process is driven by the pushing part to keep the puncture needle stable. However, the puncture needle is relatively long, and if it is pushed directly by the pushing part, the puncture needle may break or deviate, thereby affecting the puncture. Utility Model Content

[0006] Beneficial effects of this technical solution:

[0007] Insert the syringe of the puncture needle through the moving cylinder into the limiting cylinder, and rotate the driving rod so that the driving rod drives the driving frame to move, and then the sliding rod slides along the slide groove and squeezes the sliding rod so that the sliding rod drives the two clamping blocks to move relative to each other, clamping and fixing the syringe. At this time, the puncture needle is aligned with the limiting syringe. Then start the pushing part, which drives the moving cylinder to move, so as to achieve synchronous movement of the puncture needle and the syringe, and gradually insert the puncture needle into the target position. In the process of inserting the puncture needle into the target position, the puncture needle is restricted and protected by the limiting syringe, which can prevent the puncture needle from being offset or broken, thereby reducing the impact on the puncture. By fixing the syringe and connecting the puncture needle to the syringe, the puncture needle can be fixed; compared with the prior art of fixing the puncture needle, the size of the syringe is larger, and the stability of clamping and fixing with the clamping block is higher, which can improve the stability of the entire puncture operation.

During the puncture of the puncture needle, the syringe squeezes the slider to drive the movable section to slide into the fixed section, making it easier to move and insert the puncture needle.

[0016] In another preferred embodiment of the present invention, a conical guide cover is provided at one end of the movable section away from the fixed section, and the large diameter end of the guide cover faces the movable cylinder.

[0031] A moving cylinder 15 is provided in the upper part of the limiting cylinder 7, and both the upper and lower ends of the moving cylinder 15 are open. The clamping part includes two clamping blocks 16, which are both arranged in the moving cylinder 15, and the two clamping blocks 16 are arc-shaped with inner arc surfaces facing each other; the inner arc surfaces of the clamping blocks 16 are both provided with an anti-slip layer 17, and in this embodiment, the anti-slip layer 17 uses a rubber layer, and the inner side of the rubber layer is provided with anti-slip convex strips, which can increase friction and improve the clamping effect.

[0032] Combination Figure 2 As shown, the outer cover of the moving cylinder 15 is provided with a driving frame 18, and the left and right opposite inner sides of the driving frame 18 are provided with sliding grooves 19, and the depth of the sliding grooves 19 decreases from top to bottom.

During the puncture process, the movable section 11 and the fixed section 10 limit and protect the puncture needle, which can prevent the puncture needle from deflecting and reduce the probability of the puncture needle breaking due to force.

[0039] After the puncture is completed, the driving rod 21 is rotated in the opposite direction to make the driving frame 18 move in the opposite direction, so that the sliding rod 20 drives the two clamping blocks 16 to move away from each other, loosening the syringe and facilitating the removal of the syringe.
