Problems solved by technology

[0005] However, in this method, the body vessel and the flap vessel are directly anastomosed, the perfusion volume is greater than the return flow, and the flap is congested, edematous, or even necrotic.

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Such as figure 2 As shown, the present invention is a first embodiment of a flap model for vascular shunt decompression, the model includes a guide unit 1 and a shunt unit 2, the shunt unit 2 communicates with the middle of the guide unit 1, and the guide unit 1 is tubular. A connection hole 11 is defined on the side wall of the guide unit 1 , and the flow distribution unit 2 is connected to the guide unit 1 through the connection hole 11 .

[0031] In the embodiment of the present invention, the flow splitting unit 2 is in a network structure, and may also be in a star-shaped structure o...

Abstract

The invention discloses a flap model for shunt and decompression of the blood vessel. A blood vessel model comprises a guide unit and a shunt unit, and the shunt unit is communicated with the guide unit. Through a Bernoulli's effect in a fluid mechanics principle, the model is provided with the guide unit and the shunt unit, the guide unit is kept smooth, flowing of the guide unit decompresses thebranch, and infusion of the flap is reduced so that the flap load can be lowered. Through experiment and studies, all indexes after an arterialized venous flap operation are effectively improved, flap swelling is slight, no tension vesicle exists, the skin color is florid, the regurgitation is normal, the flap is high in quality in the later period, conditions like the skin color, the elasticityand the contracture are greatly improved, and the survival quality of the flap is close to that of the physiological flap.

Description

technical field [0001] The invention belongs to the technical field of medical models, in particular to a model of skin flap blood vessels. Background technique [0002] The non-physiological venous arterialized skin flap has certain clinical application value because of its advantages of convenient cutting, free location, no bloated flap, and simple operation. Since Nakayama et al. reported in 1981 that the flap experiment of venous reticular arterialization was successful, there has been an upsurge in the study of venous flaps, and the clinical application of venous flaps has been promoted. After more than 30 years of development, venous flaps have been abandoned by some clinicians because of their shortcomings such as postoperative swelling, blood stasis, and poor survival quality, and they regard them as transitional flaps. Venous flaps are non-physiological flaps, and their survival rate and survival quality are poor. Compared with physiological flaps, they have more e...
