Abstract

The utility model relates to a clinical operation assistive device, particularly to a novel blood vessel anastomat, which comprises a blood vessel scaffold and a blood vessel sleeve ring matched therewith. The blood vessel scaffold is cast from shape memory alloy and has a conical head part, the matched blood vessel scaffold can be selected according to the diameter of the blood vessel, and a handle is arranged at the tail part of the blood vessel scaffold to facilitate hand-holding of an operator. The sleeve ring is a hollow metal ring which is fabricated from shape memory alloy and has the wall thickness close to even thinner than the wall of the blood vessel, one sleeve ring surface can be longitudinally opened to be sheathed on the outer side wall of the blood vessel, and the opened sleeve ring surfaces can well fit with each other, a joint part is made from folding resistance material and does not protrude outwardly so as to avoid affecting the eversion of the blood vessel, equally spaced grooves can be designed outside the joint part as required, and the space between the grooves are designed according to the needle pitch for suturing the wall of the blood vessel.

Description

The novel vascular anastomat

Technical field

This utility model relates to a kind of clinical operation auxiliary implement, mainly is a kind of novel vascular anastomat.

Background technology

Since the sixties in 20th century, coronary artery surgery rose, vascular anastomosis just becomes higher operation of difficulty of surgical field, the technical merit that operation medium vesselses such as wound, aneurysm, organ transplantation coincide has directly caused the success or failure of operation, so vascular anastomosis also more and more is subjected to medical circle personage's common concern.Once adopted the artificial method of sewing up continuously, this kind method length consuming time demands strict technology always, and long-term effect is poor, and is difficult to the Minimally Invasive Surgery effect that reaches present.After Wicresoft's notion proposes, more generally repair the blood vessel of damage clinically at present by " noinvasive " technology of microsurgery, to obtain the best quality of coincideing, the quality of vascular anastomosis has direct influence to the reconstruction of blood circulation.Conventional manual suture's method anastomotic stoma is impacted and is expanded by blood flow easily, and the blood flow shunt volume is big, easily produces complication such as heart failure.

Summary of the invention

In order to overcome the defective that prior art exists, this utility model provides a kind of novel vascular anastomat, and this device has not only shortened the time of anastomosis of blood vessel, and greatly improves the vascular anastomosis quality, reduce complication such as hematoma ecchymosis, thrombosis, also saved a lot of valuable human resourcess of doctor.

The technical scheme that its technical problem that solves this utility model adopts is: the novel vascular anastomat is made up of the intravascular stent and the supporting with it blood vessel collar, intravascular stent is cast by marmem, the intravascular stent head is coniform, can select the intravascular stent that model is complementary according to blood vessel diameter, afterbody is a handle, and it is hand-held to be convenient to the operator.The collar by marmem forge into hollow, wall thickness near in addition be thinner than the becket of blood vessel wall, one cover anchor ring vertically can be opened and be placed in the blood vessel lateral wall, the cover anchor ring can be involutory well, joint component is that the folded special material of folding is made, and it is outwards outstanding in order to avoid influence tube wall and turn up, the joint also can be designed to the groove that there is equidistant from distance the outside as required, and flute pitch is with reference to the needle gage of sewing up blood vessel wall.

Using method of the present utility model: true disease or the patient that is suspected to have important blood vessels damage are carried out the exploration of blood vessel operation, under the pueumatic tourniquet hemostasis, expose the blood vessel of damage as much as possible.Control resolve bring out blood after, broken ends of fractured bone blood vessel is done suitably free, do not need blood vessel is pruned, unexpectedly the intravascular stent and the collar that is complementary in selecting a pair according to the diameter of the broken ends of fractured bone also is installed in the inside and outside of ends of vessels respectively, with intravascular stent broken ends of fractured bone blood vessel is strutted, vascular cuffing is located on the head of ends of vessels, broken ends of fractured bone blood vessel wall is up dug broken ends of fractured bone blood vessel wall on the blood vessel collar along the direction of intravascular stent with hands; Same method is handled another broken ends of fractured bone of blood vessel; Remove the two ends intravascular stent then, involutory blood vessel two broken ends of fractured bone make two collars be connected mutually, sew up or anastomosis of blood vessel two broken ends of fractured bone are positioned at the blood vessel wall of digging on the blood vessel collar with silk thread or nail, remove the collar at last, and vascular anastomosis is finished.

The beneficial effects of the utility model are, this blood vessel anastomat can reach the identical quality that compares favourably with the micro suture method fully in to the vascular anastomosis more than the diameter 3mm, its maximum characteristics are that handling safety (can not be sewn to and cause postoperative angiostenosis and thrombosis on the tunica intima), easy, quick (place that coincide only needs 3-7min, average 5min) and anastomotic stoma can not increase or vasospasm and subside etc. because of ambient pressure.Since need not microscope etc. special installation, therefore suit especially to promote in the hospital that is not possessing microsurgical technique and equipment.

The specific embodiment

In Fig. 1, this utility model is made up of the intravascular stent 8 and the supporting with it blood vessel collar 7, and intravascular stent 8 is cast by marmem, intravascular stent head 1 is coniform, can select the intravascular stent that model is complementary according to blood vessel diameter, afterbody 2 is a handle, and it is hand-held to be convenient to the operator.

The collar 7 by marmem forge into hollow, wall thickness near in addition be thinner than the becket of blood vessel wall, a cover anchor ring 3 vertically can be opened and be placed in the blood vessel lateral wall, cover anchor ring 3 can be involutory well.Joint 4 parts are that the folded special material of folding is made, and outwards outstanding in order to avoid influence tube wall and turn up.Joint 4 also can be designed to the groove 5 that there is equidistant from distance the outside as required, and groove 5 spacings are with reference to the needle gage of sewing up blood vessel wall.The convenient stitching after blood vessel anastomat is enclosed within on the blood vessel like this.

The marmem of making intravascular stent 8 is a niti-shaped memorial alloy, and the marmem of making the blood vessel collar 7 is the sub-thread niti-shaped memorial alloy.

Before sewing up blood vessel, this utility model intravascular stent 8 is placed in the blood vessel, again the collar 7 is placed on the blood vessel, blood vessel wall is upwards turned up, be covered on the collar 7 with hands; Handle another ends of vessels with quadrat method, pull out intravascular stent 8, two ends of vessels are folded according to original blood vessel trend give in stitching, remove the collar 7 at last, operation finishes.
