Abstract

The present invention relates to a blood vessel support frame and an operation method thereof The blood vessel support frame is structurally composed of a ring and at least one fixing portion. The ring is a C-shaped configuration having a side opening and having a diameter that is determined according to the size of a blood vessel. The fixing portion is coupled to the ring in such a manner as to be located, with the ring serving as a reference plane, at the side opposite to a blood vessel opening and spaced from the ring by a predetermined distance and extending in a direction perpendicular to the bore of the ring. A fixing element is mounted to an end of the fixing portion. With such a structure, in carrying out an operation of jointing blood vessels, an operator first uses two blood vessel support frames of different diameters in such a way that the small-diameter support frame is used to hold the outside wall of each blood vessel and the large-diameter support frame is then used to overturn the inside surface of the blood vessel and then removed. Afterwards, the fixing elements of two blood vessel support frames of the two blood vessels are connected to each other to have the openings of the two blood vessels engaging each other and then jointing of the two blood vessel may be performed. Finally, the two blood vessel support frames are removed from the blood vessels to complete the operation of jointing.

Description

Vascular support frame and method of operation thereof

The present invention provides an auxiliary instrument for use in vascular splicing surgery and an operation method thereof, which utilizes a small and notched C-ring to assist in fixing a blood vessel opening to improve the efficiency and stability of vascular engagement surgery.

In the method of vascular splicing surgery, the two blood vessels to be joined are first clamped and fixed by forceps, and the blood vessel orifices are opposite; then, at a distance from the mouth of the two blood vessels, the metal ring is sleeved on the outer wall of the second blood vessel. Then, the inner surface of the blood vessel is folded over the metal ring cover to expose the inner surface of the blood vessel; the blood vessel mouth is contacted to perform a joint operation; finally, the metal ring sleeve is removed to complete the blood vessel joint operation.

However, the procedure of conventional vascular splicing surgery is too rough, and the tools used are not only rudimentary, but also difficult to fold the blood vessels, and it is difficult to maintain good surgical quality; for example, clamping the blood vessels with forceps, it is easy to vibrate or slide due to human factors, and the metal ring The sleeve is also not easily removed after the completion of the joint surgery.

In view of this, the present inventors have made an improvement and innovation on the method of vascular splicing surgery in order to solve the above disadvantages and shortcomings, and it is expected to provide a vascular support frame with high efficiency and high stability and its operation method, and a design group. The system is used by the consumer to create the motives for the creation of the invention.

The main object of the present invention is to provide a blood vessel support frame which is sleeved on the outer wall of a blood vessel to fix it, so as to perform a blood vessel joint operation, thereby improving the efficiency and stability of the blood vessel joint surgery.

In order to achieve the above object, the structure of the blood vessel support frame of the present invention is mainly composed of a set of rings and at least one fixed portion; the collar has a preset diameter, and the diameter thereof is determined according to the diameter of the blood vessel tube to be set; Attached to the collar and extending perpendicular to the diameter of the collar.

The vascular support frame as described above is preferably a C-shaped collar having a notch.

In the blood vessel support frame as described above, it is preferable that the fixing portion is attached to the collar with a predetermined distance from the other side of the blood vessel nozzle with the collar as a reference surface.

The blood vessel support frame as described above is preferably provided with a fixing member at the end of the fixing portion, which may be a magnet, a slide rail or a disk.

The method for operating a blood vessel support frame of the present invention is mainly carried out by the following steps: first, a collar of a blood vessel support frame is sleeved on an outer wall of a blood vessel to be joined to support and fix it; and then a sleeve of another blood vessel support frame is used. The ring extends into the lumen of the blood vessel, and then folds the inner surface of the blood vessel toward the proximal end of the blood vessel, and covers it and pushes the collar of the support frame a predetermined distance. Repeat the first two steps to fix the outer wall of the other vessel to be engaged and make it inside. The face is folded over; then the fixing portion of the two-vessel support frame is fixedly connected to each other by the fixing member, so that the tube mouth of the two blood vessels touches, or one of the tube mouths is passed over the other tube mouth, and then the two blood vessels are engaged; The vascular stent is removed by sliding the blood vessel out of the blood vessel by a gap on the C-shaped collar to complete the splicing operation.

By the vascular support frame and the operation method of the invention, the operator can quickly fix the blood vessel and perform the joint operation in a stable state, and the device can be quickly removed after the operation, and the efficiency is improved in the process. It is quite novel and progressive.

The above description of the present invention and the following description of the embodiments are intended to illustrate and explain the spirit and principles of the invention, and to provide a further explanation of the scope of the invention.
