Description

A kind of Cardiac operation with mini-trauma inferior caval vein occluding device

Technical field

The utility model relates to the field of medical instrument technology, are specifically related to a kind of Cardiac operation with mini-trauma inferior caval vein blocking Device.

Background technique

Heart disease is the number one killer of human health, and the whole world is died of every year in the size of population of disease, there are about three/ First is that because disease incidence is in obvious ascendant trend always, and in China, also there are about 3,500,000 people to die of the heart every year caused by heart disease Popular name for.In more than ten years in past, minimal invasive cardiac surgery is worldwide widely used.Although so far for minimal invasive cardiac surgery Still none specific definition and specification, but having a common recognition is passed through under the premise of guaranteeing patients surgery safety Reduction surgery notch avoids extracorporal circulatory system from reaching reduction or mitigates operation to wound of both patient's human body and spirit.It is another Aspect, the diminution of operative incision will lead to the exposure of operation visual area and the more traditional center open chest surgery of operation difficulty and increased, because This, it is successfully crucial that the operation method of use and the improvement of special instrument becomes Minimally Invasive Surgery.

Inferior caval vein is the maximum vein of human body, collects the venous blood of lower limb, pelvic part and abdomen.Inferior caval vein is by left and right Common iliac vein merges, and converges position mostly in the 5th lumbar vertebrae level, flat 4th lumbar vertebrae of minority.Before inferior caval vein is located at the right side of backbone Side, along the right side uplink of abdominal aorta, sulcus for vena cava through liver, the foramen venae cavae for wearing diaphragm are opened on atrium dextrum.Needs are cut The operation of atrium dextrum, such as Treated With Repair of Auricular Septal Defect, repair if ventricular septal defect, tricuspid valvoplasty are opened, foundation follows in vitro Ring just needs row superior and inferior vena cava cuff to block, but when through the 4th intercostal into chest, since notch is small, inferior caval vein position is deep, separation Inferior caval vein cuff is highly difficult, and existing operating method generally requires that a little is isolated with pliers, needs will to hinder later Disconnected band, which passes through, to be blocked；On the one hand, extremely difficult to the separation of inferior caval vein in narrow space, greatly extend Operating time and increase operation difficulty；Even occasionally there is the generation of vena cave, left room rupture haemorrhage when dissociating by pliers；Separately On the one hand, after separating inferior caval vein with tissue, when blocking to its cuff, soft blocking band is in narrow space Being difficult elbow will block band to cover and block on inferior caval vein, bring great difficulty to operating, while also increasing patient Pain.

In conclusion problem of the existing technology is:

(1) extremely difficult to the separation of inferior caval vein in narrow space, greatly extend operating time and increase Operation difficulty, since notch is small, inferior caval vein position is deep, and separation inferior caval vein cuff is highly difficult, existing operating method one As need a little with pliers to be isolated, due to notch apart from inferior caval vein farther out, be also difficult even with pliers by Its quick separating.

(2) after separating inferior caval vein with tissue, when blocking to its cuff, soft blocking band is in narrow space Inside also being difficult elbow will block band to cover and block on inferior caval vein, operator's operating difficulties.So as to cause inferior caval vein resistance Break and occupy the too many time, while inferior caval vein cannot be effectively blocked cannot to be then operated, patient is in dusk for a long time Fan's state, which may cause, there is life danger, causes malpractice.

Utility model content

In view of the above-mentioned problems existing in the prior art, the utility model provides a kind of Cardiac operation with mini-trauma inferior caval vein resistance Disconnected device, when Cardiac operation with mini-trauma inferior caval vein is blocked and operated, inferior caval vein separation is put on blocking band by energy efficient quick It is blocked, effectively improves procedure efficiency, it is reasonable in design, be used conveniently and safely, it is suitble to medical institutions to promote the use of.

To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions:

A kind of Cardiac operation with mini-trauma inferior caval vein occluding device, including guiding device, function conduit, draught line and blocking Band；The guide head of the guiding device front end is equipped with side opening, and draught line is fixed on side opening and is reached thereafter inside guiding device End, guiding device outer wall have the side attached function conduit of side opening, are equipped in function conduit and block band, and blocking takes settable lock Determine device；

The guiding device rear end is hollow handle, and hollow handle front end, which is successively spaced, to be arranged hollow Universal pipe and lead Pipe, front end are equipped with mellow and full guide head；The guide head is equipped with side opening, the ring of setting fixed column and traction line end on side opening Set connection；The hollow handle is equipped with draught line fixing button；

The function conduit attachment and guiding device outer wall belt side opening side, function conduit are the hollow soft of front and back end opening Pipe, front opening is away from side opening 1cm, and open rearward end is away from guiding device hollow handle end 2-3cm；

The blocking band can be placed in function conduit, blocked the band head end of band to be open from function catheter proximal end and stretched out 1-2cm, It blocks end of tape to be provided with band head end and is threaded back through hole, band head end is threaded back through that bore edges are firm, and blocking band is rubber material.

Preferably, the band body for blocking band is spaced semi-cylindrical hill and belt strip, and rear end is to block band Pedestal offers and semi-cylindrical hill and the consistent semi-circular groove of belt strip and bar shaped trough of belt on pedestal.

Preferably, the universal length of tube of the guiding device be 0.5-1cm, catheter length 1-2cm, guiding device up to 10 Universal pipes are set less.

Preferably, the traction line back end is equipped with draught line handle, is connected when not pulling draught line with guiding device rear end.

Preferably, the hollow handle is equipped with 2 draught line fixing buttons, and draught line fixing button is in hollow handle axial direction Symmetrically；Draught line fixing button includes the fixing seat being placed in inside hollow handle, and pressing spring and rear end are pressed in middle position Press wedge；
