Taking the left auricle as an example, the left auricle is a long and narrow tubular blind cavity, the size of the blind cavity is equivalent to that of the thumb, the shape of the blind cavity is irregular, and multiple sections of tortuosity exist in the auricle, so that the blood flow in the auricle is easy to generate vortex and the flow speed is slowed down, and the left auricle is a good part for forming thrombus.
If grasping by an interventional method is required, none of the existing conventional forceps or instruments can be achieved. The scheme provides a novel negative pressure grabbing device which can grab specific tissues or organs in a heart cavity.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a heart intracavity tissue negative pressure grabbing device is provided, the effectual defect of overcoming prior art.
The utility model provides an above-mentioned technical problem's technical scheme as follows:
the negative pressure grabbing device comprises a connecting pipe, an air bag, a flexible adsorption part and a negative pressure device, wherein one surface of the adsorption part is arranged to be an adsorption concave surface, a negative pressure hole is formed in the middle of the adsorption concave surface, one end of the connecting pipe is connected with the other end of the adsorption part and communicated with the negative pressure hole, the other end of the connecting pipe is connected with the air bag and communicated with the air bag, and the negative pressure device is connected with the air bag and communicated with the air bag through a negative pressure pipe.
On the basis of the technical scheme, the utility model discloses can also do following improvement.
Further, the adsorption part is a medical silica gel or a flexible polymer medical rubber elastic body component.
Further, a negative pressure interface is arranged on the air bag, and the other end of the connecting pipe is connected and communicated with the negative pressure interface through an air pipe joint.
Furthermore, the waterproof breathable film filler is detachably filled in the negative pressure connecting port.
Further, the suction part is a hemispherical bowl-shaped member.
The utility model has the advantages that: structural design is reasonable, can effectually snatch target tissue through the device, and the process of snatching can not cause the hemorrhage and the damage of tissue, and the security is high.

step one, femoral artery puncture and intubation;
step two, the sheath is sent to the position of the opening of the left auricle in the left atrium under the guidance of ultrasound or radiography;
and step three, conveying the adsorption part 3 and the connecting pipe 1 of the negative pressure gripping device for the tissue in the heart chamber into the heart chamber through the sheath pipe, stretching the adsorption part 3 to the bottom of the blind end of the left auricle, starting the negative pressure device 4, generating negative pressure by the adsorption concave surface of the adsorption part 3, gripping the left auricle by utilizing the negative pressure, and turning the heart chamber inwards to realize gripping the left auricle.
The whole device has reasonable structural design, can effectively grab target tissues through the device, does not cause bleeding and damage of the tissues in the grabbing process, and has extremely high safety
In a preferred embodiment, the adsorption part 3 is a medical silica gel or a flexible polymer medical rubber elastic body member.
In this embodiment, the adsorption part 3 adopts a medical silica gel member, which can be extruded and contracted in the sheath tube, and does not damage the inner wall tissue of the heart cavity when conveying and grabbing the left auricle, so that the safety is excellent.
The flexible high polymer medical rubber elastomer component is mostly made of TPE, TPU or TPR materials.
Of course, other flexible medical material members may be used for the suction portion 3.
In a preferred embodiment, the air bag 2 is provided with a negative pressure port, and the other end of the connection tube 1 is connected to and communicated with the negative pressure port through a gas tube connector 5.
In the embodiment, the connecting pipe 1 is conveniently assembled and disassembled with the air bag 2 through the air pipe joint 5, and is easy to replace and maintain.
In a preferred embodiment, the negative pressure port is detachably filled with a waterproof/liquid permeable membrane filler 6.
In this embodiment, the waterproof breathable film packing 6 is designed to prevent part of blood and impurities entering through the connecting tube 1 from entering the air bag 2 for storage, and not entering the negative pressure tube 41 further, so that the normal use of the negative pressure device 4 is not affected.
As a preferred embodiment, the adsorption part 3 is a hemispherical bowl-shaped member, and the shape design is reasonable, so that negative pressure is facilitated to adsorb inner wall tissues of the left auricle, and good grabbing and inversion operations of the left auricle are realized.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
