Abstract
A channeling device capable of easily forming a channel between a regeneration and healing site and a bone marrow is disclosed. A channeling device for forming a channel for inducing a bone marrow healing material includes a channeler body, a channeler rod connected to one end of the channeler body, a channeler tip formed at the tip of the channeler rod to penetrate into the bone marrow, And a tip blade protruding from the circumferential surface of the channeling tip so as to penetrate into the bone marrow.
Description
BACKGROUND OF THE
Previously, there was no clear understanding of the healing and regeneration process of the tissue. For example, in the case of cartilage regeneration, a superclot is formed in the cartilage defect through so-called chondroplasty and microfracture And this is expected to be regenerated as cartilage, and this procedure is now most commonly performed in cartilage regeneration.
However, the fact that blood is important for tissue healing is lacking in empirical and scientific evidence, and it has recently been found that healing substances, which can be represented by stem cells and growth factors, are important for healing and regeneration of such tissues .
Meanwhile, recently, a method of injecting stem cells and growth factors from outside has been suggested for more effective tissue regeneration. In this connection, Korean Patent Laid-Open No. 10-2012-0096236 (published on Aug. 30, 2012) discloses "joint treatment agent and joint treatment method using adipose stem cells" Suggesting a method of regenerating cartilage, ligaments, tendons and muscles by directly injecting fat-derived adipose stem cells into the joints.
However, in the case of injecting stem cells and growth factors from the outside, there is a possibility that the cost for the procedure is excessively required and there is a problem about stability. Further, in the case of the external injection method, a separate extraction process is required to extract stem cells and growth factors, and the extraction process takes a long time, which makes it difficult to perform the procedure directly on the patient.
Recently, some countermeasures have been proposed to simplify tissue regeneration and reduce cost and time, but it is still insufficient and development thereof is required. Recently, various studies have been made to regenerate tissues by using healing substances in the human body.
The present invention provides a channeling device capable of facilitating movement and mobilization of a healing material directly from a bone marrow containing a large amount of a healing material, and facilitating formation of a channel between the healing part and the bone marrow.
In addition, the present invention provides a channeling device capable of easily forming a channel for guiding a healing substance while minimizing damage of bones.
The present invention also provides a channeling device that simplifies tissue regeneration procedures and saves cost and time.
According to another aspect of the present invention, there is provided a channeling device for forming a channel for introducing a healing material in a bone marrow, comprising: a channeler body; a channeler rod connected to one end of the channeler body; And a tip blade protruding from the circumferential surface of the channeling tip so as to penetrate into the bone marrow around the channeling tip.
For reference, the channeling device according to the present invention can be used for a channel for connecting regeneration and healing parts and bone marrow, and the present invention is not limited or limited by the use site and use of the channeling device. For example, the channeling device according to the present invention can be used for repairing a rotator cuff that attaches a rotator cuff (tendon) to the humerus (arm bone).
The shape of the channeler tip can be changed appropriately according to the required conditions and design specifications. For example, the channeler tip may be formed to have a reduced cross-sectional area toward the distal end, and a sharp apex may be formed at the tip of the channeler tip. Further, an indicator for indicating the depth of insertion may be formed on the surface of the channeler tip.
In addition, the channeler tip may be disposed on a straight line along the longitudinal direction of the channel rod, but in some cases it is possible for the channeler tip to be disposed obliquely with respect to the longitudinal direction of the channel rod. Also, it is possible that only one channeler tip is provided for one rod, but a plurality of channeler tips are formed at the end or middle of the rod while maintaining a constant angle.
The tip blade is provided to form a peripheral channel around the main channel by the channeler tip, so that more healing material contained in the bone marrow flows out while minimizing bone damage.
The tip blade can be formed in various structures penetrating into the bone marrow around the channeler tip, and the structure of the tip blade can be appropriately changed according to the required conditions and design specifications. For example, the tip blade may be formed to have a reduced cross-sectional area from the proximal end to the distal end adjacent to the circumferential surface of the channeler tip. Preferably, the tip blade may be provided in a shape in which the vertical cross section is continuously protruded in the longitudinal direction of the channeler tip by a triangle, and the length of the base of the tip blade in which the vertical cross section is triangular is formed to be smaller than the diameter of the channeler tip .
In addition, a plurality of tip blades may be provided so as to be spaced along the circumferential direction of the channeler tip, and the number and spacing of the tip blades may be appropriately changed according to the required conditions and the characteristics of the patient. For example, when the bones to be treated are exposed to the outside of the tendon, three or four tip blades may be used at regular intervals along the circumferential direction of the channeler tip. As another example, when the bone to be treated is covered by tendons, two tip blades may be used so that they are arranged in the same line along the diametrical direction of the channeler tip.
According to the channeling device of the present invention, it is possible to facilitate the channel between the regeneration and healing part and the bone marrow to promote the movement and mobilization of the healing material directly from the bone marrow.
Particularly, according to the present invention, by forming the tip blade on the outer circumferential surface of the channeler tip, it is possible to form a channel capable of ejecting more healing material while maintaining the structural strength. That is, as the diameter of the channeler tip becomes larger, a larger main channel can be formed, so that more bone marrow can be flowed out. However, as the size of the main channel by the channeler tip becomes larger, There is a problem. Particularly, when a patient having a weak bone is treated, it is difficult to use a channeler tip having a diameter larger than a predetermined value in order to maintain the structural strength of the bone, and accordingly, sufficient bone marrow is difficult to flow out. However, according to the present invention, by using the channeler tip and the tip blade together, the size of the main channel that substantially affects the structural strength of the bone can be reduced, and a region (peripheral channel) through which bone marrow can flow can be additionally secured .
Further, according to the present invention, the tissue regeneration procedure can be simplified and cost and time can be saved.
