Abstract
The invention discloses an animal heart instant fixing device. The animal heart instant fixing device structurally comprises a handle and a heart fixing ring, wherein the handle is composed of a first handle and a second handle; a through hole is formed in the upper end of the first handle; an inserting sheet is arranged at the upper end of the second handle; the inserting sheet is inserted into the through hole; the lower end of the first handle is crossed with the lower end of the second handle; the heart fixing ring is in an oval shape formed by bending a steel wire with a round cross section; two free ends of the heart fixing ring are connected with two free ends of the two crossed handles. The fixing device can be used for finishing heart operation in a short time, the stimulation time on a heart is shortened, and the death rate in intraoperative and postoperative processes of animals is reduced.
Description
Technical field
The present invention relates to a kind of holder, specifically animal hearts instantaneous set device.
Background technology
In cardiovascular clinical and basic scientific research field, carried out at body by toy (large and small Mus)
Zoopery is indispensable, and especially application rat prepares ischemia-reperfusion and ami model etc.
Research clinical disease.During preparing animal model, need heart coronary artery left anterior descending branch is entered
Row ligatures or carries out drug injection at each position of heart.After model preparation, when animal remains a need for raising one section
Between, therefore, improve the survival rate of animal in model preparation process, experiment success rate will be greatly improved.
When carrying out toy cardiac procedures at present, as a example by prepared by rat model of myocardial infarction, heart does not enters
Row is fixing, due to about 350 beats/min of kinds of rat heart rate, and fast 3.5 times or more of adult of ratio, it is difficult to operation,
Usually must repeatedly ligature heart, excessive to heart and injury, cause rats death rate too high.Toy heart
Holder is by operating handle and arc retainer ring forms.As a example by prepared by rat model of myocardial infarction, use
Time, retainer ring is placed in the lower section of heart, lifts to thoracic cavity opening part gently, expose coronary artery left front
Descending branch, after ligaturing this blood vessel, unclamps retainer ring, it is taken out below heart, completes operation.
Summary of the invention
It is an object of the invention to provide animal hearts instantaneous set device, this holder can be at short notice
Complete cardiac procedures, shorten the stimulation time to heart, reduce in animal art and postoperative mortality rate.
The present invention solves its technical problem and is adopted the technical scheme that: animal hearts instantaneous set device, its
Structure includes handle and heart retainer ring, and described handle is made up of first handle and second handle, described
The upper end of one handle is provided with through hole, and 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 is arranged in a crossed manner with the lower end of second handle, and described heart retainer ring is by cross section
For circular steel wire bent ovalisation, and after two of heart retainer ring are intersected with two handles by end
Two free ends connect.
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, and heart is fixed
The arc-shaped bend angle of ring end 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 and second-hand
Handle is isometric, wide, uniform thickness, a diameter of 1mm of described heart retainer ring.
The invention has the beneficial effects as follows:
(1) as required by heart instantaneous set in certain position, cardiac procedures can be smoothly completed,
Reduce the operation failure caused of quickly beating because of heart.It addition, utilize the toy heart fastener can be
Complete cardiac procedures in short time, shorten the stimulation time to heart, reduce in animal art and postoperative dead
Die rate.
(2) size of retainer ring can be adjusted as required with extrusion handle, the most concentric to adapt to animal
The demand that dirty size and different parts are fixed, meets large and small zooperal demand.
(3) retainer ring uses circular stainless steel silk to make, and can regulate retainer ring size by handle,
It is facilitated to enter thoracic cavity with multi-angle；Round wire design can avoid holder to damage thoracic organ, reaches
To undamaged effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the structural representation of first handle；
Fig. 4 is the structural representation of second handle.
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, the animal hearts instantaneous set device of the present invention is described in detail below.
As shown in Figures 1 to 4, the animal hearts instantaneous set device of the present invention, its structure include handle and
Heart retainer ring 3, described handle is made up of first handle 1 and second handle 4, described first handle 1
Upper end is provided with through hole 11, and the upper end of second handle 4 is provided with inserted sheet 41, and described inserted sheet 41 is inserted with through hole 11
Connecing, the lower end of described first handle 1 is arranged in a crossed manner with the lower end of second handle 4, described heart retainer ring 3
It is circular steel wire bent ovalisation by cross section, and two of heart retainer ring are by end and two handles
Two free ends after intersection connect.Retainer ring uses circular stainless steel silk to make, and can be adjusted by handle
Joint heart retainer ring 3 size, facilitates it to enter thoracic cavity with multi-angle；Round wire design can be avoided solid
Determine device damage thoracic organ, reach undamaged effect.
The outside of described first handle 1 and second handle 4 is respectively equipped with multiple anti-skidding protruding 2.Can prevent
Skid when finger and handle 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, heart retainer ring end
Arc-shaped bend 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 with second handle,
Wide, uniform thickness, a diameter of 1mm of described heart retainer ring.
As required by heart instantaneous set in certain position, cardiac procedures can be smoothly completed, reduce
Quickly beat because of heart the operation failure caused.It addition, utilize the toy heart fastener can be in short-term
In complete cardiac procedures, shorten the stimulation time to heart, reduce in animal art and postoperative mortality rate.
First handle and second handle can be extruded as required to adjust the size of retainer ring, to adapt to move
The demand that thing difference cardiac 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,
