Description
Technical field
This utility model relates to a kind of holder, 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 Mus)
Can or lack, especially application rat prepares the research clinical disease such as ischemia-reperfusion and ami model.Dynamic in preparation
During object model, need heart coronary artery left anterior descending branch to be ligatured or carries out drug injection at each position of heart.
After model preparation, animal remains a need for raising a period of time, therefore, improves the survival rate of animal in model preparation process, will significantly
Improve experiment success rate.
When carrying out toy cardiac procedures at present, as a example by prepared by rat model of myocardial infarction, heart is not fixed, by
In about 350 beats/min of kinds of rat heart rate, fast 3.5 times or more of adult of ratio, it is difficult to operation, usually must repeatedly ligature heart, to the heart
Dirty damage is excessive, causes rats death rate too high.Toy heart fastener is by operating handle and arc retainer ring forms.With greatly
As a example by the preparation of Mus myocardial infarction model, during use, retainer ring is placed in the lower section of heart, lifts to thoracic cavity opening part gently, cruelly
Dew left anterior descending coronary artery, after ligaturing this blood vessel, unclamps retainer ring, it is taken out below heart, completes operation.
Utility model content
The purpose of this utility model is to provide animal hearts instantaneous set device, and this holder can complete at short notice
Cardiac procedures, shortens the stimulation time to heart, reduces in animal art and postoperative mortality rate.
The technical scheme in the invention for solving the technical problem is: animal hearts instantaneous set device, its structure
Including handle and heart retainer ring, described handle is made up of first handle and second handle, and the upper end of described first handle is provided with
Through hole, the upper end of second handle is provided with inserted sheet, described inserted sheet and through hole grafting, the lower end of described first handle and second handle
Lower end is arranged in a crossed manner, and described heart retainer ring is circular steel wire bent ovalisation by cross section, and the two of heart retainer ring
Individual by holding two free ends after intersecting with two handles to be connected.
Further, the outside of described first handle and second handle is respectively equipped with multiple anti-skidding projection.
Further, the arc-shaped bend angle of described first handle and second handle is angle A, the arc of heart retainer ring end
Shape angle of bend is angle B, and described angle A is 140 °, and described angle B is 100 °.
Further, the long 5cm of described first handle, wide 0.8cm, thick 0.5mm, first handle is isometric, wide with second handle,
Uniform thickness, a diameter of 1mm of described heart retainer ring.
The beneficial effects of the utility model are:
(1) as required by heart instantaneous set in certain position, can smoothly complete cardiac procedures, reduce because of heart
Quickly beat the operation failure caused.It addition, utilize toy heart fastener can complete cardiac procedures at short notice, contracting
The short stimulation time to heart, reduces in animal art and postoperative mortality rate.
(2) size of retainer ring can be adjusted as required with extrusion handle, to adapt to animal difference cardiac size and not
With the demand that position is fixing, meet large and small zooperal demand.
(3) retainer ring uses circular stainless steel silk to make, and can regulate retainer ring size by handle, facilitates it with polygonal
Degree enters thoracic cavity；Round wire design can avoid holder to damage thoracic organ, reaches undamaged effect.

In figure:
1 first handle, 11 through holes, 2 anti-skidding projections, 3 heart retainer ring, 4 second handles, 41 inserted sheets, angle A, angle B.
Detailed description of the invention
With reference to Figure of description, animal hearts instantaneous set device of the present utility model is described in detail below.
As shown in Figures 1 to 4, animal hearts instantaneous set device of the present utility model, its structure includes that handle and heart are solid
Determining ring 3, described handle is made up of first handle 1 and second handle 4, and the upper end of described first handle 1 is provided with through hole 11, second-hand
The upper end of handle 4 is provided with inserted sheet 41, described inserted sheet 41 and through hole 11 grafting, the lower end of described first handle 1 and second handle 4 times
Holding arranged in a crossed manner, described heart retainer ring 3 is circular steel wire bent ovalisation by cross section, and two of heart retainer ring
Two free ends after being intersected with two handles by end are connected.Retainer ring uses circular stainless steel silk to make, and can pass through handle
Regulation heart retainer ring 3 size, facilitates it to enter thoracic cavity with multi-angle；Round wire design can avoid holder to damage thoracic cavity
Internal organs, reach undamaged effect.
The outside of described first handle 1 and second handle 4 is respectively equipped with multiple anti-skidding protruding 2.Finger and handle can be prevented
Skid during contact, it is ensured that the fastness of holder of taking.
The arc-shaped bend angle of described first handle and second handle is angle A, the arc-shaped bend of heart retainer ring end
Angle is angle B, and described angle A is 140 °, and described angle B is 100 °.
The long 5cm of described first handle, wide 0.8cm, thick 0.5mm, first handle is isometric, wide with second handle, uniform thickness, institute
State a diameter of 1mm of heart retainer ring.
As required by heart instantaneous set in certain position, cardiac procedures can be smoothly completed, reduce because heart is fast
Speed is beated the operation failure caused.It addition, utilize toy heart fastener can complete cardiac procedures at short notice, shorten
Stimulation time to heart, reduces in animal art and postoperative mortality rate.
First handle and second handle can be extruded as required to adjust the size of retainer ring, the most concentric to adapt to animal
The demand that dirty size and different parts are fixed, meets large and small zooperal demand.
Using method: as a example by prepared by acute rat model of myocardial infarction.Hand-held toy holder handle, by retainer ring
It is placed in the lower section of heart, lifts to thoracic cavity opening part gently, adjust retainer ring position below heart as required.The most sudden and the most violent
After dew left anterior descending coronary artery blood vessel, inserting needle ligation blood vessel.After completing above-mentioned steps, unclamp retainer ring, by it from heart
Side takes out, and completes operation.
The above, simply explain through diagrams principles more of the present utility model, and this specification is not intended to this practicality
Novel be confined in shown described concrete structure and the scope of application, thus every corresponding amendment being likely utilized and etc.
