Background
The heart is one of the most important organs in the vertebrate body and has the primary function of providing pressure for blood flow to move the blood to various parts of the body. The heart functions to promote blood flow, provide sufficient blood flow to organs and tissues to supply oxygen and various nutrients, and remove metabolic end products (such as carbon dioxide, inorganic salts, urea, uric acid, etc.), so that cells maintain normal metabolism and function. In heart major vascular surgery, it is often necessary to occlude a section of a blood vessel so that the adjacent vessel to the site of the occlusion can be opened for the surgical procedure. The existing occlusion methods are mainly performed using aortic clamps. However, the great cardiac vascular surgery often requires a long operation time, and if the aorta is clamped by using the aortic clamp for blood flow blockage, the time course causes adhesion of the inner wall of the blood vessel. Therefore, the aortic clamp needs to be loosened at regular time intervals in the operation process, the opening of the aortic clamp is loosened, blood flows out of the aorta, the blood loss in the operation is increased, and the operation risk is increased. And after the aortic forceps are loosened, a large amount of blood can be gushed into the operation field to shield the operation field, so that blood sucking operation is required, the operation is complicated, the operation time is prolonged, and the operation risk is further increased.

After the front-section limiting piece 10 is elastically restored, the rear-section limiting piece 14 still extrudes and deforms the blood vessel wall towards the inside of the blood vessel. At this time, the vessel wall extruded by the front-stage limiting piece 10 contacts with one end of the internal blocking plug 2, and the vessel wall extruded by the rear-stage limiting piece 14 contacts with the other end of the internal blocking plug 2, so that the positions of the two ends of the internal blocking plug 2 are fixed, and the internal blocking plug 2 is prevented from being separated from the blood vessel due to the peristalsis of the blood vessel.
The inner sleeve 1 is also sleeved with a middle section fastening sleeve ring 18, and the middle section fastening sleeve ring 18 is positioned between the front section outer sleeve ring 4 and the rear section outer sleeve ring 5; middle section fastening lantern ring 18 is formed the annular by two semicircle ring docks, and middle section fastening lantern ring 18 has cup jointed middle section elasticity clamping ring 23 outward, and two semicircle ring inboards of middle section fastening lantern ring 18 are provided with a semicircular middle section clamping ring 19 respectively, are provided with a plurality of elastic support pole 20 between middle section fastening lantern ring 18 and the middle section clamping ring 19, and the contact is sticis with 1 surface of inside casing to the tight clamping ring inner wall in middle section 19.
The technical scheme of this application has still set up middle section fastening lantern ring 18, blocks when inside to fill in after the blood vessel is filled in to stopper 2, cup joints the middle section fastening lantern ring 18 that two semicircle rings butt joints formed between anterior segment outer thimble 4 and back end outer thimble 5, cup joints elastic belt on the surface of middle section fastening lantern ring 18 and ties for middle section fastening lantern ring 18 is fixed. Middle section clamping ring 19 is pressed to inside sleeve pipe 1 surface under the squeezing action of middle section fastening lantern ring 18, and then can extrude inside in blood vessel and the blood vessel and block stopper 2, make inside surface and the blood vessel inner wall that blocks stopper 2 sticis the contact, the frictional force through inside surface and the blood vessel inner wall that blocks stopper 2 further fixes inside position that blocks stopper 2, and owing to increased inside surface and the blood vessel inner wall's that blocks stopper 2 pressure, make inside block stopper 2 inseparabler with the blood vessel contact, further prevent that blood from flowing out.
The elastic support rod 20 is an arc-shaped elastic rod.
The elastic support rods 20 absorb excessive pressure by elastic deformation when the middle-stage tightening collar 18 applies pressure to the middle-stage tightening collar 19, so that the pressure can be maintained within a range that the blood vessel wall can withstand.
The two ends of the internal blocking plug 2 are conical, the end part of the internal blocking plug 2 is fixedly connected with a traction rod 21, and the end part of the traction rod 21 is provided with a traction ring 22.
The pulling rod 21 and the pulling loop 22 facilitate the manual handling of the internal occlusion plug 2 for placing and removing the internal occlusion plug 2 into and out of the blood vessel.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art should understand that they can make various changes, modifications, additions and substitutions within the spirit and scope of the present invention.
