Incubation nourishing circulation system for easily necrotic tissues

Abstract

The invention relates to an incubation nourishing circulation system for easily necrotic tissues. The circulation system comprises a culture chamber, wherein an inlet of the culture chamber is connected with a culture liquid supply device; an outlet of the culture chamber communicates with the inlet of the culture chamber through a pipeline to form the circulation system; and the front end and / or the back end of the culture chamber are / is provided with a one-way sealing structure through which limbs can enter and / or extend out of the culture chamber. The circulation system provided by the invention is particularly suitable for nourishing naked tissues such as nerves, skeletons and muscle tendons; sterile and proper culture conditions are provided for the tissues; the tissue necrosis and the dysfunction are prevented; the tissue healing can be promoted; debridement is realized; nutrition is provided; and the repair surgery in the later period is convenient.

Description

technical field [0001] The invention belongs to the field of clinical tissue protection and regeneration equipment, and in particular relates to a warming and nourishing circulation system for easily necrotic tissues. Background technique [0002] Clinically, it is often seen that nerves, bones or tendons are exposed due to mechanical trauma such as car accidents and cuttings. In this case, it is necessary to repair and cover the nerves, bones or tendons as soon as possible to avoid necrosis and residual tissue caused by the above-mentioned tissues being exposed for too long. Limbs and other functional impairments. [0003] At present, the following two methods are mostly used for repair: 1. Use surrounding tissue suture to cover the exposed nerve, bone or tendon. This method can directly suture the defect covering the exposed nerve, bone or tendon. It is currently widely used in clinical practice, and the operation is simple and convenient. It is convenient, but it is only...

AI Technical Summary

Problems solved by technology

[0003] At present, the following two methods are mostly used for repair: 1. Use surrounding tissue suture to cover the exposed nerve, bone or tendon. This method can directly suture the defect covering the exposed nerve, bone or tendon. It is currently widely used in clinical practice, and the operation is simple and convenient. It is convenient, but it is only suitable for the situation of light tissue damage, few defects, and not serious pollution, and it is not suitable for wounds with high infection risk and infected wounds with heavy local pollution; 2. Using skin flaps to repair exposed nerves, Bone or tendon, this method can repair trauma with large defects, but it requires the patient's vital signs to be stable, and it is not suitable for wounds with severe local pollution and high risk of infection, nor for wounds that have already been infected

[0004] Therefore, in the prior art, the patient's injury is heavy, the vital signs are not stable, or the local injury is so heavy that the first-stage surgical repair cannot be performed in time, and the exposed time is too long, and eventually the tissue is necrotic, and the remaining dysfunction is regrettable for life.

At present, no treatment other than self-tissue repair has been found
