Problems solved by technology

[0003] When performing pericardiocentesis, you need to be very careful. Use imaging equipment to observe the position of the puncture needle to ensure that the puncture needle can accurately enter the pericardial cavity and avoid damage to the heart. However, the pericardiocentesis is performed manually by medical staff During the puncture, hand shaking may occur during the manual operation. At the same time, during the insertion process, the diaphragm in the cavity obstructs the puncture needle, making the puncture position inaccurate, and the puncture pressure is too small to be able to penetrate. Penetrating the pericardial cavity, too much force can easily cause damage to the heart, so it is necessary to provide a self-contained pressure pericardiocentesis device to solve the above problems

Embodiment 1

[0035] When the present invention is in use, the patient is first laid flat on the operating bed, and the patient's top is taken off, and the accurate puncture position is drawn on the patient's chest to determine the subsequent surgical puncture position, and then the installation and fixation of the device is prepared. Rotate the second threaded ring 19 on both sides of the equipment board 1, so that the adjustment screw 18 moves outward from the two sides of the equipment board 1 to ensure that the equipment board 1 is directly above the position of the patient's chest cavity, and at the same time make the two sets of decks 5 It is located on both sides of the operating table, and then the fixing jacket 21 is fixedly clamped on the side edge of the operating table, and fixed and installed through the locking bolts on the side of the fixing jacket 21, and then the equipment board 1 is pressed down, and the device Plate 1 drives two groups of card holders 5 to slide downward o...

Embodiment 2

[0037] After completing Embodiment 1, the puncture needle 12 is inserted from the position of the draw-in groove 14 to the inside of the adjustment tube 4, and the bottom end of the puncture needle 12 passes through the hollow tube 2 and enters downward into the inside of the tapered tube 11, At this time, the clamping rod 15 on the top of the puncture needle 12 enters the inside of the clamping groove 14, and then the adjusting heads 137 on both sides of the fixing seat 10 are rotated to make the first threaded rod 131 and the second threaded rod 132 rotate synchronously. The cylinder 133 moves in the middle of the outer surface of the first threaded rod 131 and the second threaded rod 132 respectively, and is slidably connected directly above the chute through the slider 134 at the bottom. The two groups of clamping blocks 136 move to the middle, so that the two groups of clamping blocks 136 enter the inside of the clamping groove 14, and finally the two groups of clamping bl...

Embodiment 3

[0039] After completing Embodiment 2, the bottom end of the puncture needle 12 is now inside the conical tube 11, and the bottom end of the conical tube 11 is in contact with the patient's skin. The adjusting tube 4 moves to the inside of the hollow tube 2. At this time, the adjusting tube 4 drives the fixing seat 10 to move downward through the connecting plate 9, and the fixing seat 10 drives the puncture needle 12 to move downward slowly, and finally the bottom end of the puncture needle 12 is stabbed. Piercing the patient's skin, and inserting it into the patient's pericardial cavity from the designated operation position, during this process, the limit rods 7 on the lower surfaces of the two sides of the connecting plate 9 slide downward inside the limit sleeve 22, and the regulating tube The movement of 4 is limited to prevent the adjustment tube 4 from rotating with the first threaded ring 8. At this time, the doctor can observe the moving distance of the end of the punc...

Abstract

The invention discloses a self-negative-pressure pericardium puncture device, and relates to the field of pericardium puncture. According to the self-negative-pressure pericardium puncture device, a hollow tube is fixedly connected to the upper surface of an equipment plate; the bottom end of the hollow tube extends to the lower surface of the equipment plate to be fixedly connected with a transparent cover; an adjusting tube is connected to the top end of the hollow tube through screw threads; a fixing seat is fixedly connected to the top of the adjusting tube; a puncture needle is movably inserted and connected to the upper surface of the fixing seat; a fixing assembly is movably clamped and connected with the side surface of the fixing seat; the end part of the fixing assembly extends into the fixing seat and is movably clamped and connected with the puncture needle; a clamp seat is connected to each of two sides of the equipment plate through screw threads; a rack is movably inserted and connected into the upper surface of each clamp seat; and the bottom end of each rack extends to the lower side of the corresponding clamp seat to be fixedly connected with a fixing jacket. Theself-negative-pressure pericardium puncture device has the advantages that the puncture position of the puncture needle is effectively limited; the situation that the puncture force is not well controlled is avoided; and meanwhile, the injury to a patient caused by hand shaking or position deviation in manual operation is reduced.

Description

technical field [0001] The invention relates to the technical field of pericardial puncture, in particular to a self-contained pressure pericardial puncture device. Background technique [0002] Pericardiocentesis is a diagnosis and treatment technique that directly penetrates the pericardial cavity with the help of a puncture needle. Pericardiocentesis must be performed under aseptic technique, local application of procaine anesthesia, and the puncture site should not be too deep, so as not to puncture the atrium, ventricle or puncture the coronary artery A large amount of blood in the pericardial cavity is caused. Patients with pericardial puncture can understand the nature of pericardial effusion by testing the fluid in the pericardial cavity, and find out the cause of pericarditis according to the nature of pericardial effusion. [0003] When performing pericardiocentesis, you need to be very careful. Use imaging equipment to observe the position of the puncture needle t...
