Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, and in particular to a pericardiocentesis positioning device. Background Art

[0002] Pericardiocentesis is a diagnostic and treatment technique that uses a puncture needle to directly puncture the pericardial cavity. Pericardiocentesis must be performed under sterile techniques, with local application of procaine anesthesia. The puncture site should not be too deep to avoid puncturing the atrium, ventricle or coronary artery, causing a large amount of blood accumulation in the pericardial cavity. Patients who undergo pericardiocentesis can understand the nature of pericardial effusion by testing the fluid in the pericardial cavity, and identify the cause of pericarditis based on the nature of the pericardial effusion.

[0003] The utility model patent with publication number CN219147799U discloses a puncture positioning device for pericardiocentesis, including a puncture plate, the front surface of which is fixedly connected to a puncture tube; a first positioning mechanism, the first positioning mechanism includes a first movable plate, and the first movable plate is slidably connected to the puncture tube, the side surface of the first movable plate is fixedly connected to a first limit plate, and the lower surface of the first limit plate is provided with a first rubber strip; a second positioning mechanism, the second positioning mechanism includes a second movable plate, and the second movable plate is slidably connected to the puncture tube, the side surface of the second movable plate is fixedly connected to a second limit plate, and the second limit plate is engaged with the first movable plate, and the upper surface of the second limit plate is provided with a second rubber strip.

[0004] In the prior art, when a patient is punctured, the friction between the puncture needle and the first limiting plate and the second limiting plate can be increased, so that the puncture needle is not easily deflected during use. However, the following problems still exist:

[0005] 1. The puncture positioning device for pericardiocentesis of the prior art (CN219147799U) controls the front end of the puncture needle to prevent it from deviating easily by the friction between the puncture needle and the first and second limit plates. However, the rear end of the puncture needle is not fixed, and the puncture needle is long and is not easily fixed firmly, resulting in the bending of the puncture needle. It is also inconvenient to adjust the puncture angle of the puncture needle, and pericardiocentesis cannot be performed at multiple angles.

[0006] 2. The puncture positioning device for pericardiocentesis in the prior art (CN219147799U) fixes the cover cloth by snapping the first and second hidden buttons together, so that the hemostatic block on the cover cloth stops bleeding at the puncture site. However, there is no downward pressure mechanism to press the hemostatic block, resulting in a poor compression hemostasis effect. Utility Model Content

[0007] In view of the deficiencies of the prior art, the present invention provides the following technical solutions:

[0008] A pericardial puncture positioning device comprises a base plate and a hemostasis device, wherein a puncture hole is provided on the base plate, and a puncture device is slidably arranged on the base plate along the edge of the puncture hole, wherein the puncture device comprises a telescopic rod, one end of which is slidably connected to the base plate, and the other end of which is rotatably connected to a sliding base, wherein a fixed plate is slidably arranged on the sliding base, and sliding grooves are symmetrically provided on the fixed plate, wherein a clamping block is slidably arranged in the sliding groove, and a clamping bolt is threadedly connected in the sliding groove to abut against the clamping block, and the clamping bolt is rotated to control the sliding of the clamping block;

[0009] The hemostatic device includes a compression plate and a loading plate slidably connected to a bottom plate. The compression plate and the loading plate are connected via an elastic element. A hemostatic block is arranged below the compression plate. The compression bolt threadedly connected to the bottom plate is rotated to push the compression plate downward, thereby driving the hemostatic block to move downward.

[0010] Furthermore, restraint belts are provided on both sides of the bottom plate, and a plurality of suction cups are provided on the bottom surface of the bottom plate.

[0011] Furthermore, a limit plate is provided on the side of the fixed plate and extends to the side of the sliding base. The limit plate is threadedly connected to a limit bolt. The limit bolt is controlled to contact the side of the sliding base by rotating the limit bolt to limit the sliding of the fixed plate.

[0012] Furthermore, an arc groove is provided on the bottom plate along the edge of the puncture hole, and the telescopic rod slides along the arc groove by arranging a sliding block, and the sliding of the sliding block is limited by threading a sliding bolt on the sliding block.

[0013] Furthermore, a mounting groove is provided in the bottom plate and connected to the puncture hole, and the loading plate is slidably mounted in the mounting groove.

[0014] Furthermore, a circular downwardly protruding structure adapted to the puncture hole is provided at the front end of the compression plate, the hemostatic block is arranged below the protruding structure, and an arc-shaped notch is provided below the front end of the carrier plate.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The utility model slides a puncture device on the arc groove at the edge of the puncture hole of the bottom plate, and the puncture device is rotatably connected to the sliding base through the telescopic rod. A fixed plate is slidably arranged on the sliding base, and the puncture angle of the puncture needle on the fixed plate can be flexibly adjusted, which solves the problem that the puncture angle of the puncture needle is not convenient to adjust in the prior art (CN219147799U) and pericardial puncture cannot be performed at multiple angles. A sliding bolt is set on the sliding block under the telescopic rod to limit the sliding of the puncture device on the bottom plate;

[0017] 2. The utility model connects the compression plate to the carrier plate of the hemostatic device through an elastic element, and arranges a circular protruding structure below the front end of the compression plate, and arranges a hemostatic block below the protruding structure. By tightening the compression bolt on the bottom plate, the compression plate is pressed downward, thereby driving the hemostatic block to move downward, compressing the hemostatic puncture position, and solving the problem that the prior art (CN219147799U) lacks a downward pressing mechanism to press the hemostatic block, resulting in an insignificant compression hemostatic effect.

[0018] 3. The utility model slides a fixing plate on the sliding base, and slides a clamping block in a sliding groove symmetrically provided on the fixing plate. The clamping bolts on the fixing plate are tightened to press against the clamping blocks to move toward each other and clamp the puncture needle, so that the puncture needle is fixed on the fixing plate. The puncture is achieved by sliding the fixing plate. A limiting plate is provided on the side of the fixing plate, and the limiting bolts on the limiting plate are tightened to make the limiting bolts contact and squeeze the sliding base to limit the sliding of the fixing plate. This solves the problem of the prior art (CN219147799U) that the front end of the puncture needle is not easily deviated by the friction between the puncture needle and the first limiting plate and the second limiting plate, but the rear end of the puncture needle is not fixed, and the puncture needle is long and is not easily fixed firmly, resulting in bending of the puncture needle.
