Technical Field
The utility model relates to a surgical instrument, in particular to a blood vessel threading tool for mouse aortic stenosis.
Background
At present, the aortic stenosis operation adopted for constructing the mouse pressure overload cardiac hypertrophy is mostly finished by using ophthalmic micro-elbow forceps to pick up and thread the aorta, and the method has the following defects: 1. because the metal forceps are made of hard materials, the aorta is easy to rupture and bleed, the subject loses blood and dies, and the modeling fails; 2. because the ophthalmic micro-forceps is not a special instrument for the operation, the design is not enough, the instrument needs to rotate by a larger angle when the aorta is picked up, and the aorta is easy to be torn due to over-stretching; 3. sufficient space is required to manipulate the device, thereby exposing a larger wound, exacerbating the subject's trauma, bleeding and stress, and further increasing mortality.
SUMMERY OF THE UTILITY MODEL
The invention of the utility model aims to: aiming at the existing problems, the wire passing tool for the mouse aortic stenosis operation blood vessel is provided to reduce the operation trauma probability and reduce the operation visual field requirement through a small structural design.
The utility model adopts the technical scheme as follows:
a mouse aorta coarctation operation blood vessel threading tool comprises a handle part, a neck part and a head part, wherein one end of the neck part is connected to the handle part along the axial direction of the handle part, and the head part is connected to the other end of the neck part; the head part is in a hook shape and is integrally bent towards the extending direction deviating from the neck part; the free end of the head part is provided with at least one small hole.
The integral bending means that the plane of the head portion is deflected in a direction away from the extending direction of the neck portion, and the deflection angle is usually more than 45 degrees.
The blood vessel threading tool is small in structure, low in requirement on visual field, easy in threading process and not easy to damage an acting target.
Further, the head part is spirally raised along the extending direction of the neck part, and the length of the head part is less than half of the circumference.
Further, the neck and the head are equal in diameter.
Further, the diameter of the neck and the diameter of the head are both 0.7 mm.
Furthermore, the minimum aperture of the small hole formed in the free end of the head is not smaller than the diameter of the 6-0 silk thread.
Further, the handle is made of rigid metal or plastic.
Further, the neck and head are both made of a rigid metal.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
the instrument has relatively low requirement on the operation visual field, does not need to cut pectoralis major and ribs, has small wound, does not cause the tearing of blood vessels, has easy and smooth threading process, high operation efficiency and high survival rate.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
As shown in FIGS. 1 to 3, the present embodiment discloses a blood vessel passing tool for mouse aortic stenosis, which comprises a handle 1, a neck 2 and a head 3. One end of the neck 2 is connected to the handle 1 along the axial direction of the handle 1, and the head 3 is connected to the other end of the neck 2. The head 3 is hook-shaped and is bent as a whole in a direction deviating from the extension direction of the neck 2. The so-called integral bending is that the plane in which the head 3 (both ends) lie deviates from the direction in which the neck 2 extends. In one embodiment, the deflection angle is between 60 and 90 degrees. The free end 4 of the head 3 is provided with at least one small hole 5. The aperture 5 is used to thread a suture.
Example two
As shown in FIGS. 1 to 3, the present embodiment discloses a blood vessel passing tool for mouse aortic stenosis, which comprises a handle 1, a neck 2 and a head 3. The handle 1 is made of metal or plastic, and is convenient to hold. The neck 2 and the head 3 are both made of a rigid metal. The tip of the handle 1 is tapered, one end of the neck 2 is connected to the tip of the handle 1 in the axial direction of the handle 1, and the head 3 is connected to the other end of the neck 2. The neck 2 and head 3 are, in one embodiment, of equal diameter. In a particular embodiment, the neck 2 and head 3 are each 0.7mm in diameter. The head 3 is helical in the direction of extension of the neck 2, with a length within half a turn (half turn or less). At least one small hole 5 is arranged at the free end 4 of the head 3 for threading. The minimum aperture of the small holes 5 is designed to be capable of passing 6-0 silk thread.
EXAMPLE III
The embodiment takes a mouse as an example and discloses the working principle of the blood vessel threading tool for the aortic stenosis of the mouse:
the mouse is fixed on a mouse board after anesthesia, a small animal breathing machine is connected behind a tracheal cannula, the skin is cut beside the left sternum, the whole pectoralis major muscle is separated bluntly from the outer edge, the pectoralis major muscle is picked up, the intercostal muscle is penetrated into the intercostal muscle from the 2 nd to the 3 rd intercostal by a micro elbow forceps, the rib is opened, the left chest cavity is exposed, a sternum spreader is placed, the thymus is peeled by the micro forceps, the aorta is exposed, the head of the thread passing tool is threaded through 6-0 silk thread, the handle part 1 is held by the right hand, the head end is aligned to the lower edge of the aorta and is slightly picked up, the handle part 1 is rotated about 135 degrees, the head 3 is threaded out from the 1 st to the 2 nd branch of the aorta, the thread is pulled out by the sharp forceps by the left hand, the thread passing tool is withdrawn along the original path by the reverse rotation of the right hand to complete the placement of the binding, the operation is completed.
The instrument has relatively low requirement on the operation visual field, does not need to cut pectoralis major and ribs, has small wound, does not cause the tearing of blood vessels, has easy and smooth threading process, high operation efficiency and high survival rate.
