Abstract: An apparatus for operating a syringe has developed comprising: an upper semi-cylindrical tube section, semi-circular shaped locking groove and lower semi-cylindrical tube section. The upper semi-cylindrical tube section is integrally formed an upper head part with a threaded hole for axial movement. The lower semi-cylindrical tube section forms a top portion, intermediate portion and end portion. A diameter (Dc) at the intermediate portion larger than the diameter (Dtip) at end portion is gradually reduced from intermediate to end portion. The length of the tapered portion is same as that portion of the constant diameter. A tip portion has formed an opened semi-circular shape to simply overlap the syringe over the cartridge for easily snapping-in and out. The syringe piston moves downward with no reverse action when the piston press-unit is rotated, thus it is possible to inject the precise amount of medicine to a patient with constant pressure.

Abstract: The present invention relates to a composition for cartilaginous tissue repair and to a production method therefor. The present invention comprises the steps of: (a) dissolving freeze-dried fibrinogen in an aprotinin solution; (b) dissolving freeze-dried thrombin in a stabilizing solution; (c) mixing an enriched collagen solution with thrombin and the stabilizing solution; and installing the fibrinogen solution (a) to one side of a dual kit and the solution (c) containing the collagen to the other side, and then mixing and injecting into damaged cartilaginous tissue. In the present invention, which is constituted as described above, biomaterials such as collagen and fibrin are mixed so as to allow damaged cartilaginous tissue to be repaired to a state allowing transplantation onto the tissue, and efficient regeneration is induced, thereby making it possible to reduce surgery-related stress on people and animals while inducing relatively rapid and efficient cartilage repair and regeneration.

Abstract: Disclosed herein is a method for preparing a collagen gel composition for bone regeneration comprising collecting bone marrow from animal tissues and isolating nucleated cells from the bone marrow; and mixing the nucleated cells and a bio-matrix composed of type I collagen and apatite.

Abstract: A compound for bone forming and a method for producing the same are provided using a mixture of an osteoblast and a bio-matrix. The method comprises: isolating osteoblasts from bone tissue and culturing the isolated osteoblasts to prepare an osteoblast suspension; and mixing the resulting osteoblast suspension with a bio-matrix to prepare an osteoblast therapeutic agent. A bone formation method is provided that results in no clinical graft rejection, and is capable of achieving effective and rapid bone formation via injection of a compound which has been pre-shaped to a certain extent, so as to alleviate problems associated with bone tissue formation in unwanted regions resulting from escape of injected osteoblasts from the targeted site for bone formation and then propagation thereof to other sites via the blood stream, which are caused by injection of an osteoblast suspension.

Abstract: An apparatus for operating a syringe piston is developed, which is comprised of: a syringe mounting section for fixedly holding a syringe, a thread hole formed at an upper head part of the syringe mounting section, and a piston press unit having a threaded rod, which is inserted into the thread hole so that the syringe piston press unit can move up and down along the thread hole, a locking slot for fixedly inserting and retaining the medicine filled syringe, a semi-cylindrical tube to assemble with the syringe mounting section. The syringe filled with medical cement is attached to the syringe mounting section and the syringe piston is moved downward with no reverse movement when the piston press unit is rotated, so the medical cement contained in the syringe is injected with a constant pressure, so that a predetermined amount of medical cement is precisely injected into a patient's body.

Abstract: The present invention relates to a method for separating bone marrow-derived nucleated cells for bone formation. The method comprises: the steps of: washing bone marrow; lysing red blood cells in the bone marrow; neutralizing the bone marrow lysate; purifying nucleated cells from the neutralized bone marrow; and mixing the nucleated cells with a maintenance buffer for bone formation. According to the invention, bone marrow-derived nucleated cells, which can be grafted into a site in need of bone formation or bone defect treatment, can be separated in a rapid and convenient manner. As a result, bone formation in emergency patients or patients, who require repeated surgical operations, can be effectively achieved by separating the nucleated cells for bone formation in surgical locations in a convenient and rapid manner and injecting the separated cells into the patients.

Abstract: A method for producing the fibrin contained semi-solid osteoblast composition has developed for treating the bone fracture. The method is comprised of: isolating osteoblasts from a bone tissue and culturing/proliferating the isolated osteoblasts in Dulbecco's Modified Eagle's Medium (DMEM) or Minimum Essential Medium, Alpha Modification (?-MEM) to prepare an osteoblast suspension. Then, mixing the resulting osteoblast suspension with a coagulation factor to prepare an osteoblast therapeutic agent. Accordingly, the fibrin contained semi-solid osteoblast composition of the present invention has capability to achieve the bone grafting for performing bone union without the clinical graft rejection. It is possible to uniformly distribute the fibrin mixed semi-solid osteoblast composition into the affected area of the bone fracture via injection. Therefore, the fibrin contained semi-solid osteoblast composition is effectively and rapidly cure the bone fracture via constant injection of into the affected area.
