Vascular anastomosis fixing support apparatus and operation method thereof

Abstract

The invention discloses a vascular anastomosis fixing support apparatus and an operation method thereof. The vascular anastomosis fixing support apparatus comprises a main support part and a bending part extending upwards along one end of the main support; the main support part includes an upper surface and a lower surface, the middle of the upper surface of the main support part extends upwards to form a raised support part, and the middle of the top face of the raised support part sinks inwards to form a support camber surface to fit the vessel; positioning strips used for positioning the vessels are respectively arranged on the upper surface of the main support part and two sides of the raised support part; a plurality of overflow holes are further formed in the main support part and isarranged in the manner of penetrating the upper surface and the lower surface of the main support part; the main support part uses bright colors such as green to distinguish easily, and horizontal and vertical scales are arranged on the upper surface of the main support part. By the arrangement, the anastomosed vessels can be placed smoothly without infiltrating in the nearby cerebrospinal fluidor blood and other fluids and can be completely exposed to the surgeon's line of sight, and convenience in operation is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical blood vessel suture lap joint anastomosis instruments, and in particular relates to a fixed support device for blood vessel anastomosis and an operation method thereof. Background technique [0002] Vascular anastomosis is a basic form of surgery in clinical practice, including vascular injury repair, vascular grafting, vascular lapping, vascular suture and repair, etc. It is an effective treatment method commonly used to rebuild blood flow. It is widely used in various surgical operations, such as replantation of severed limbs, accidental vascular injury, organ transplantation, arteriovenous fistula anastomosis, etc. With the continuous development of microsurgical instruments, microsutures and operating microscopes, manual small (micro) vascular anastomosis techniques have gradually matured, and the diameter of blood vessels that can be anastomotic is getting smaller and smaller.

AI Technical Summary

Problems solved by technology

Let’s take the suture of intracranial blood vessels as an example to see the difficulties faced: firstly, the surrounding environment of the blood vessels to be anastomotic is relatively complicated. There are many nerves / fibers and various brain tissues around any blood vessels, and the blood vessels will be infiltrated in the cerebrospinal fluid. It is not easy to distinguish blood vessels with similar colors from the mixed liquid composed of blood and the cleaning solution and nutrient solution that are continuously injected externally during the operation, and long-term operation will cause visual fatigue and increase misoperation Risk; in addition, the diameter of the blood vessels to be anastomotic is relatively small, ranging from a few tenths of a millimeter to two to three millimeters. After the blood flow is clamped, it becomes very soft and slippery. When the instrument is in contact, it will move, and the position is difficult to fix. It is not easy Suture; in addition, the patient is in a dormant or semi-dormant state, but the beating of the heart is still transmitted to various parts of the body, especially the cerebrovascular and nerve parts, which are in an unstable state during the anastomosis operation, and the surgeon's instruments need to be very careful during the suture operation. Be cautious to avoid puncturing nearby tissues and free nerves and blood vessels; the last point is that blood vessels and related tissues lose their nutritional supply after clipping. If this state lasts too long, it will cause inactivation or even complete necrosis. There is a high requirement for suturing time

For the very fine anastomosis that needs to be performed under a microscope, these external conditions are not conducive to the judgment of the operator, which increases the difficulty of the operation of the medical staff and affects the efficiency and quality of the operation.

[0004] At this stage, some flexible sheets or gauze are usually used to assist the suture operation. Although some problems can be solved, the efficiency is still not high and the function is single and not standardized.
