The invention discloses a kind of animal hearts instantaneous set device, its structure includes handle and heart retainer ring, the handle is made up of first handle and second handle, the upper end of the first handle is provided with through hole, the upper end of second handle is provided with inserted sheet, the inserted sheet and through hole grafting, the lower end of the first handle is arranged in a crossed manner with the lower end of second handle, the heart retainer ring is circular steel wire bent ovalisation by cross section, and two of heart retainer ring intersected with two handles by end after two free ends be connected.The fixator can in a short time complete cardiac procedures, shorten the stimulation time to heart, reduce in animal art and the postoperative death rate.
Description
Technical field
The present invention relates to a kind of fixator, specifically animal hearts instantaneous set device.
Background technology
In cardiovascular clinical and basic scientific research field, carried out in body zoopery not by toy (large and small mouse)
Or can lack, especially prepare the research clinical disease such as ischemia-reperfusion and ami model using rat.It is dynamic preparing
, it is necessary to be ligatured to heart coronary artery left anterior descending branch or carry out drug injection at each position of heart during thing model.
After prepared by model, animal stills need to raise a period of time, therefore, the survival rate of animal in model preparation process is improved, will significantly
Improve experiment success rate.
When carrying out toy cardiac procedures at present, by taking rat model of myocardial infarction preparation as an example, heart is not fixed, by
It is not easy to operate than being grown up fast 3.5 times or more in 350 beats/min of kinds of rat heart rate or so, heart usually must be repeatedly ligatured, to the heart
It is dirty to damage excessive, cause rats death rate too high.Toy heart fastener is made up of operation handle and arc retainer ring.With big
As a example by prepared by mouse myocardial infarction model, when using, retainer ring is placed in the lower section of heart, is gently lifted at the opening of thoracic cavity, cruelly
Dew LADCA, after ligaturing the blood vessel, unclamps retainer ring, and it is taken out from heart lower section, completes operation.
The content of the invention
It is an object of the invention to provide animal hearts instantaneous set device, the fixator can in a short time complete heart
Operation, shortens to the stimulation time of heart, reduces in animal art and the postoperative death rate.
The technical scheme adopted by the invention to solve the technical problem is that：Animal hearts instantaneous set device, its structure includes
Handle and heart retainer ring, the handle are made up of first handle and second handle, and the upper end of the first handle is provided with through hole,
The upper end of second handle is provided with inserted sheet, the inserted sheet and through hole grafting, the lower end of the first handle and the lower end of second handle
Arranged in a crossed manner, the heart retainer ring is circular steel wire bent ovalisation by cross section, and two of heart retainer ring by
Two free ends after end intersects with two handles are connected.
Further, multiple anti-skid bulges are respectively equipped with the outside of the first handle and second handle.
Further, the arc-shaped bend angle of the first handle and second handle is angle A, the arc of heart retainer ring end
Shape angle of bend is angle B, and the angle A is 140 °, and the angle B is 100 °.
Further, first handle 5cm long, width 0.8cm, thickness 0.5mm, first handle and second handle be isometric, wide,
Uniform thickness, a diameter of 1mm of the heart retainer ring.
The beneficial effects of the invention are as follows：
(1) as needed by heart instantaneous set in certain position, cardiac procedures can be smoothly completed, is reduced because of heart
Quickly beat the operation failure for causing.In addition, can in a short time complete cardiac procedures using toy heart fastener, contract
The short stimulation time to heart, reduce animal art in and the postoperative death rate.
(2) size of retainer ring can be adjusted with extrusion handle as needed, to adapt to animal difference cardiac size and not
With the demand that position is fixed, the demand of large and small zoopery is met.
(3) retainer ring is made of circular stainless steel wire, and can adjust retainer ring size by handle, facilitates it with polygonal
Degree enters thoracic cavity；Round wire design can avoid fixator from damaging thoracic organ, reach undamaged effect.

Specific embodiment
Animal hearts instantaneous set device of the invention is described in detail below with reference to Figure of description.
As shown in Figures 1 to 4, animal hearts instantaneous set device of the invention, its structure includes handle and heart retainer ring
3, the handle is made up of first handle 1 and second handle 4, and the upper end of the first handle 1 is provided with through hole 11, second handle 4
Upper end be provided with inserted sheet 41, the inserted sheet 41 and the grafting of through hole 11, the lower end of the first handle 1 and the lower end of second handle 4
Arranged in a crossed manner, the heart retainer ring 3 is circular steel wire bent ovalisation by cross section, and two of heart retainer ring by
Two free ends after end intersects with two handles are connected.Retainer ring is made of circular stainless steel wire, and can be adjusted by handle
The size of section heart retainer ring 3, facilitates it to enter thoracic cavity with multi-angle；It is dirty that round wire design can avoid fixator from damaging thoracic cavity
Device, reaches undamaged effect.
The outside of the first handle 1 and second handle 4 is respectively equipped with multiple anti-skid bulges 2.Finger and handle can be prevented
Skidded during contact, it is ensured that the fastness of fixator of taking.
The arc-shaped bend angle of the first handle and second handle is angle A, the arc-shaped bend of heart retainer ring end
Angle is angle B, and the angle A is 140 °, and the angle B is 100 °.
The first handle 5cm long, width 0.8cm, thickness 0.5mm, first handle is isometric, wide with second handle, uniform thickness, institute
State a diameter of 1mm of heart retainer ring.
As needed by heart instantaneous set in certain position, cardiac procedures can be smoothly completed, reduced because heart is fast
The operation failure that speed bounce causes.In addition, can in a short time complete cardiac procedures using toy heart fastener, shorten
To the stimulation time of heart, reduce in animal art and the postoperative death rate.
First handle and second handle can be extruded as needed to adjust the size of retainer ring, to adapt to animal decentraction
The demand that dirty size and different parts are fixed, meets the demand of large and small zoopery.
Application method：By taking the preparation of acute rat model of myocardial infarction as an example.Hand-held toy fixator handle, by retainer ring
The lower section of heart is placed in, is gently lifted at the opening of thoracic cavity, position of the retainer ring below heart is adjusted as needed.It is fully sudden and violent
After dew LADCA blood vessel, inserting needle ligation blood vessel.After completing above-mentioned steps, retainer ring is unclamped, by it under heart
Side takes out, and completes operation.
The above, simply explain through diagrams some principles of the invention, and this specification is not intended to limit to the present invention
In shown described concrete structure and the scope of application, therefore every corresponding modification for being possible to be utilized and equivalent,
Belong to apllied the scope of the claims of the invention.
In addition to technical characteristic described in specification, remaining technical characteristic is technology known to those skilled in the art.
