Abstract

The present invention relates to a body volume substitute comprising cartilage for grafting by injection, and a dual needle-type syringe for injecting same. The volume substitute of the present invention is characterized by comprising one or more types selected from ground cartilage, physiological saline, and body fluid. According to the present invention, it is possible to graft a volume substitute not only for repairing skin tissue damage caused by an external injury and augmenting skin from a cosmetic point of view, but also for repairing skeletal tissue loss and augmenting skeletal tissue volume, by a simple method of injection. In addition, using the syringe of the present invention, it is possible to finely adjust the amount of injection solution being injected when injecting the body volume substitute into a human body, thereby precluding the danger to a patient caused by an overdose of the injection solution.

Description

Technical field

[0001] The present invention relates to a body volume replacement material for injection and transplantation containing cartilage, and more particularly relates to repairing damage or increasing the volume of soft tissue not only for damage repair of skin tissue due to trauma, etc., but also for cosmetically increased skin volume. Large, also used for defect repair of skeleton tissue and augmentation of skeleton tissue, body volume replacement material for injection transplantation including cartilage.

[0002] In addition, the present invention relates to a syringe for injecting the body volume replacement material for injection and transplantation into the human body, and in particular, relates to a device that can exclude patients caused by excessive administration of injection fluid by finely adjusting the amount of injection fluid injected. Dangerous double needle syringe.

Embodiment Construction

[0062] 【1. Manufacture of body volume substitute material】

[0063] Utilize ear cartilage that is easily obtained from the body as donor cartilage ( figure 1 ). Cartilage tissue structure Due to the presence of various fibrous structures in the matrix, chondrocytes are contained in the cartilage cavity, and the fibrous structure and chondrocytes are basically not damaged. The donor cartilage is preferentially cut into 1mm in the length direction and enlarged for transplantation It is easy to spread due to the tissue of the site and the contact area. According to the type of cartilage in the donor part, it undergoes a softening process that is slightly different but not strong, so as to preserve the direction of the elastic fibers or other fibers of the cartilage, and crushes and grows along the texture. About 0.5mm in width each ( figure 2 ). Thereafter, after filling the crushed cartilage into a 1cc syringe ( image 3 ), mixed saline ( Figure 4 ), the crushed cartilage...
