Abstract
The utility model provides an aorta tube inserting device for extracorporal circulatory system, includes that intubate, aorta fill the needle and block the sacculus, the intubate is restrainted by the intubate of being responsible for and the looped pipeline constitutes, the person in charge is the one -pipe that comprises the aorta intubate, and the looped pipeline is filled the needle and blocked the device by the aorta to fill the double -pipeline that the needle constitutes, the opening opposite direction of the person in charge and looped pipeline, blocking and being equipped with the passageway that fills that link up in the sacculus, the aorta fills the needle and passes and fill the passageway and get into ascending aorta, is equipped with the injection port on blocking the sacculus wall of sacculus, blocks the device and fills cushion and go into the injection port and get into and block inside the sacculus. Because the intubate is restrainted for the intubate of being responsible for and the looped pipeline constitutes to block the sacculus setting on the looped pipeline, so during extrinsic cycle under construction three -dimensional, it can only to need to sew up a pocket in ascending aorta department. Not only avoided the free operation of too much dissection, simplified the flow of establishhing and withdrawing the extracorporal circulatory system operation, moreover because sufficient operating space is also reserved for follow -up operation technique to the structural integration of whole device.
Description
Technical field
This utility model belongs to technical field of medical instruments, and a kind of aorta for extracorporeal circulation is inserted
Pipe device.
Background technology
The extensively application of extracorporeal circulation makes endocardial open surgery be achieved, almost at all of heart
In surgical operation, the auxiliary of extracorporeal circulation is all necessary requirement.Setting up and withdrawing extracorporeal circulation is department of cardiac surgery
Perform the operation necessary operation, and it be exactly aortic cannulation that all of extracorporeal circulation is required for step at least,
Aortic perfusion and aorta clamping.
Existing aortic cannulation device is as it is shown in figure 1, include aortic cannulation 4, catheter needle 2 and block pincers
3.Sew up at ascending aorta 1 distal end and be placed into aortic cannulation 4, intubate tip towards distal end.Enter
The blood of aortic cannulation 4 is arterial blood, and enters body circulation, carries oxygen perfusion systemic organs.And
Need to sew up at proximal part and be placed into catheter needle 2.Be cardioplegic solution through the liquid of catheter needle 2 infusion, due to
There is notable difference in blood constituent and temperature between aortic cannulation 4, both blood can not mix, therefore
Between the two by blocking pincers 3 blocking-up.
When using existing aortic cannulation device to set up extracorporeal circulation clinically at present, need before cardiac arrest
Sew up pocket at two at ascending aorta, and need group on rear side of free ascending aorta and pulmonary artery gap and aorta
Knit to facilitate and appear.Especially the most repeatedly open in the patient of breast at secondary, vertical adhesion of diaphragm is obvious, any trip
All will increase hemorrhage risk from operation, and this is this hemorrhage, it tends to be difficult to control, not only need infusion big
Amount blood product, even may result in patient and occurs that severe complication is the most dead time serious.
Utility model content
In view of this, this utility model provides a kind of aortic cannulation device for extracorporeal circulation, it is possible to will
Aortic cannulation, aortic perfusion and aorta clamping are integrated on a device, corresponding in a liter active
Arteries and veins sews up a pocket, it is not necessary to the too much free operation of dissection, reduces operating process, and then reduces foundation
With withdraw cardiopulmonary bypass time, the most also operate for subsequent procedures simultaneously and reserve enough working places.
The technical solution of the utility model is, a kind of aortic cannulation device for extracorporeal circulation, including inserting
Pipe, aortic perfusion pin and blocking vessel, it is characterised in that intubate described in: and be made up of supervisor and looped pipeline
Intubate bundle；Described supervisor is the one-pipe being made up of aortic cannulation, and described looped pipeline is to be filled by described aorta
The twin flue that note pin and blocking vessel filling needle are constituted；The opening direction of described supervisor and looped pipeline is contrary, supervisor
Opening point to distal end, the opening of looped pipeline points to proximal part；Described blocking vessel is for blocking sacculus, this resistance
Being provided with through perfusion channel in interception capsule, described aortic perfusion pin enters through this perfusion channel and rises actively
The proximal part of arteries and veins, the balloon wall of described blocking-up sacculus is provided with injection port, and described blocking vessel filling needle inserts
Injection port enters and blocks balloon interior is to block sacculus to be filled with.
Further, described blocking-up sacculus is elliposoidal.
The beneficial effects of the utility model are, intubate bundle owing to intubating for what supervisor and looped pipeline were constituted, and insert
Tube bank is then to be made up of aortic cannulation, aortic perfusion pin and blocking vessel filling needle, and blocks sacculus
It is arranged on the looped pipeline intubating bundle, so when patient sets up extracorporeal circulation for patient, only need to be at ascending aorta
A pocket is sewed up at place.Not only avoid and too much dissect free operation, simplify foundation and withdraw external
The flow process of circulation operation, and due to the integration on whole apparatus structure, also reserve foot for subsequent procedures operation
Enough working places.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing aortic cannulation device.
Fig. 2 is structural representation of the present utility model.
In figure: 1. ascending aorta, 2. catheter needle, 3. block pincers, 4. aortic cannulation, 5. block sacculus,
6. aortic perfusion pin, 7. blocking vessel filling needle.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with attached
The utility model is described in further detail with specific embodiment for figure.
As in figure 2 it is shown, a kind of aortic cannulation device for extracorporeal circulation, including intubating, aorta fills
Note pin 6 and blocking vessel.Intubate and intubated bundle by what supervisor and looped pipeline were constituted.Wherein, supervisor is by actively
Arteries and veins intubates the one-pipe of 4 compositions, and looped pipeline is made up of aortic perfusion pin 6 and blocking vessel filling needle 7
Twin flue.It should be noted that the opening direction of supervisor and looped pipeline is contrary.Wherein, supervisor is aorta
The opening intubating 4 points to distal end, looped pipeline i.e. aortic perfusion pin 6 and the opening of blocking vessel filling needle 7
Point to proximal part.Blocking vessel, for blocking sacculus 5, is provided with through perfusion channel in this blocking-up sacculus 5, main
Arterial perfusion pin 6 enters the proximal part of ascending aorta 1 through this perfusion channel.Block the balloon wall of sacculus 5
Being provided with injection port, it is to block sacculus 5 that blocking vessel filling needle 7 insert injection port to enter blocking-up sacculus 5 internal
It is filled with.
In order to increase the barrier effect blocking sacculus 5, therefore blocking-up sacculus 5 is set to elliposoidal.
This utility model in use, first, is sewed up one at ascending aorta 1 and only needs a pocket, will
Composition intubates the aortic cannulation 4 of bundle, aortic perfusion pin 6 and blocking vessel filling needle 7, and blocks ball
Capsule 5 is placed in ascending aorta 1.The opening of aortic cannulation 4 is positioned at distal end, aortic perfusion pin 6 He
The opening of blocking vessel filling needle 7 is positioned at proximal part.Now, blocking sacculus 5 is collapsed mode.Secondly,
By blocking vessel filling needle 7 to blocking injecting normal saline in sacculus 5, blocking-up sacculus 5 is made to be sufficient filling with
Expand, reach intracavity and block the purpose of aorta.Then, perfused hearts is started by aortic perfusion pin 6
Cardioplegic solution, makes cardiac arrest.Finally, patient starts follow-up operation technique.
