Description
Technical field
The utility model relates to the field of medical instrument technology, in particular to a kind of auricle clamp conveying device.
Background technique
Atrial fibrillation is clinically one of most common arrhythmia cordis illness, and blood flows into and out the speed of auricle when atrial fibrillation occurs
Degree can be very low, and in clinical manifestation, the left auricle of heart entrance of atrial fibrillation patient is obviously broadening, and auricle loses effective rule and shrinks, auricle
Wall movement is difficult to that enough left auricle of hearts is caused to empty, and causes blood to deposit in left auricle of heart, and then thrombus easy to form, these thrombus
The cerebrovascular or in vivo other blood vessels may be blocked, cerebral apoplexy or other illnesss are caused.The cerebral apoplexy consequence as caused by atrial fibrillation is non-
Chang Yanchong, the death rate and disability rate reach 70%.Non-valvular atrial fibrillation is the high-incidence type of one of atrial fibrillation, in non-valvular room
In quivering, the formation of 90% or more thrombus is related with left auricle of heart.
For prevention atrial fibrillation cerebral arterial thrombosis, mainly there are three approach at present:
The first is to take anticoagulant treatment, such as warfarin, but application warfarin has certain bleeding risk, and palpus
It frequently to monitor, contraindication and side effect are relatively more, and clinical application is more difficult；
Second is surgical resection left auricle of heart, but since to be closed completely rate lower for the left auricle of heart of this method, previously
Researches show that the success rates a maximum of about of 80% of complete excision left auricle of heart；
The third is to close left auricle of heart using instrument.This method is divided into again percutaneously to be intervened outside intracardiac left auricle of heart closing and heart
Section's operation or Minimally Invasive Surgery ligature auricle.Intracardiac left atrial appendage occlusion art product is percutaneously intervened, such as percutaneous catheter occluder for left auricle
Deng, but since this method is complicated for operation, the reasons such as risk is higher, and safety and validity are still to be tested, not yet large-scale application
In clinic.Cardiac operation or Minimally Invasive Surgery ligation auricle are a kind of current widely used therapeutic modalities.

It is adjacent to compacting on ear, realizes the closing of left auricle of heart, a possibility that reduce thrombosis.
But auricle clamp 9 itself has preferable elasticity, after being maintained at open state, then cuts hookup wire 72, can make auricle
Folder 9 is closed suddenly, may be misplaced with left auricle of heart in this way, be influenced sealing effect.In order to weaken the influence of the problem, defeated
The opening and closing element 8 for being provided on device and being closed auricle clamp 9 gently is sent, opening and closing element 8 includes flexible air-bag 81, appendix 82 and gas
Source 83, flexible air-bag 81 are set as two, are placed between the first clamp arm of auricle clamp 9 and the second clamp arm the gas transmission (referring to Fig. 2)
The output end of pipe 82 is connected with two flexible air-bags 81, and input terminal is connected to gas source 83；Gas source 83 be chosen as air pump, inflator or
Sphygmomanometer inflatable ball is selected as sphygmomanometer inflatable ball here.
Auricle clamp 9 is installed on a conveyor by hookup wire 72, and appendix 82 and gas source 83 are solid also by hookup wire 72
Determine on a conveyor, before auricle clamp 9 is sent into human body, first presses pressurized air source 83, gas is passed into flexible air-bag by appendix 82
In 81, flexible air-bag 81 is expanded to be fixed between the first clamp arm and the second clamp arm, is then sent auricle clamp 9 by conveying device
Enter human body, the first clamp arm and the second clamp arm is made to be located at the root of left auricle of heart, cuts hookup wire 72, auricle clamp 9 is because of flexible air-bag 81
Support will not be closed, slowly bleed off the gas in gas source 83 and flexible air-bag 81, the first clamp arm of auricle clamp 9 and second at this time
Clamp arm slowly resets immediately, so that gently stable be clamped on left auricle of heart, avoids the first clamp arm and the second clamp arm unexpected with this
Closure and left auricle of heart are there is a situation where misplacing, to ensure that the sealing effect of left auricle of heart.Auricle clamp 9 is clamped on left auricle of heart
Afterwards, spaced between the first clamp arm and the second clamp arm, it will not influence the separation of flexible air-bag 81 Yu auricle clamp 9, so that auricle
Folder 9 can easily be removed from conveying device, ensure the safety of surgical procedure.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
