Description

{CHANNELING DEVICE FOR BONE MARROW STIMULATION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a channeling device, and more particularly, to a channeling device capable of forming a channel for effectively inducing a bone marrow healing substance.

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments. In describing the present invention, a detailed description of well-known functions or constructions may be omitted for clarity of the present invention.

FIG. 1 is a view showing a channeling apparatus according to the present invention, and FIG. 2 is a view for explaining a tip blade as a channeling apparatus according to the present invention. 3 to 5 are views for explaining a modification of the channeling apparatus according to the present invention.

As shown in these figures, the channeling apparatus 100 according to the present invention includes a channel body 110, a channeler rod 120, a channeler tip 130, and a tip blade 140.

For reference, the channeling device 100 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 limited or limited by the use site and use of the channeling device 100 no. For example, the channeling device 100 according to the present invention can be used for repairing a rotator cuff that attaches the rotator cuff (tendon) to the humerus (arm bone). The bone marrow inside the bone attaches to the tendon (A hole in the bone) to allow the blood to flow well to the site (suture site) to be treated.

1 and 2, the channeler body 110 may be provided with various structures capable of gripping the practitioner, and the material of the channeler body 110 may be appropriately changed according to required conditions and design specifications. For example, the channel body 110 may have a circular cross section and may have a substantially cylindrical shape with a predetermined length. In addition, the channeler body 110 may be provided with a general additional function such as a slip prevention function, and the present invention is not limited or limited by the type and characteristics of the channeler body 110.

The channeler rod 120 is connected to one end of the channeler body 110 and a channeler tip 130 to be described later is formed at a distal end of the channeler rod 120.

The channel rod 120 may be provided in various structures that can be connected to one end of the channel body 110. For example, the channel rod 120 may have a circular cross section having a smaller size than the channel body 110 and may be formed in a straight line shape having a predetermined length. In addition, since the channel rod 120 can enter the human body during the procedure, it is preferable that the channel rod 120 is formed of a material having biocompatibility with the human body.

In addition, a flat portion 110 for hammering may be formed at the other end of the channel body 110. The flat portion 112 prevents slippage during hammering to form a channel and enables more effective transmission of force.

The channeler tip 130 is formed at a distal end of the channel rod 120 to substantially pierce the bone, and can penetrate into the bone marrow.

The shape of the channeler tip 130 can be appropriately changed according to required conditions and design specifications. The channeler tip 130 may have a reduced cross-sectional area toward the distal end, and a sharp vertex may be formed at the tip of the channeler tip 130.

A channel (see FIG. 6A) corresponding to the cross-sectional shape of the channeler tip 130 may be formed through the channel by the channeler tip 130, and a bone marrow Can flow out.

In the embodiment of the present invention, only a part of the channel adjacent to the tip end of the channel tip is formed to have a reduced cross-sectional area toward the tip. In some cases, however, it can be formed to have a gradually reduced sectional area from the proximal end to the distal end.

In addition, an indicator 150 for indicating the depth of insertion may be formed on the surface of the channeler tip 130. For example, a laser marking portion for indicating an insertion depth may be formed on the surface of the channeler tip 130, and a practitioner can confirm the insertion depth of the channeler tip 130 by checking the laser marking portion.

In the embodiment of the present invention, only one indicator is formed on the surface of the channeler tip. However, in some cases, it is possible to form a plurality of indicators according to the depth of insertion. The present invention is not limited thereto.

The tip blade 140 protrudes from the circumferential surface of the channeler tip 130 so as to permeate into the bone marrow around the channeler tip 130.

The tip blade 140 forms a peripheral channel (see B in FIG. 6) around the main channel by the channeler tip 130 so that the healing material contained in the bone marrow can flow out more while minimizing damage to the bone. .

That is, as the diameter of the channeler tip 130 increases, a larger size 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 130 increases, the structural strength of the bone may deteriorate. Particularly, when a patient having a weak bone is treated, it is difficult to use the channeler tip 130 having a diameter larger than a predetermined diameter in order to maintain the structural strength of the bone, so that sufficient bone marrow is difficult to flow. In contrast, the present invention uses channeler tip 130 and tip blade 140 together to reduce the size of the main channel, which substantially affects the structural strength of the bone, ) In addition to the above.

The tip blade 140 may have various structures that can penetrate into the bone marrow from the periphery of the channeler tip 130. The structure of the tip blade 140 may be appropriately changed according to required conditions and design specifications.

The tip blade 140 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 130. In such a structure, a portion of the peripheral channel region formed by the tip blade 140 adjacent to the main channel described above is formed relatively wide, and a portion relatively farther from the main channel is formed relatively narrowly, While maintaining the strength of the bone. Hereinafter, the tip blade 140 will be described in which the vertical cross section is provided in the shape of a triangle extending continuously along the longitudinal direction of the channeler tip 130. Preferably, the length of the base W of the tip blade 140 whose vertical section is triangular is less than the diameter R of the channeler tip 130.

Although the channeler tip 130 and the tip blade 140 are integrally formed in the channel rod 120 in this embodiment, the channeler tip and the tip blade may be provided interchangeably in the channel rod, A hole or threaded hole may be formed at the end and the chip may be replaceably mounted in the hole or threaded hole.

In other cases, a tip blade may also be provided interchangeably with the tip. For example, it is possible to provide a plurality of separate structures along the longitudinal direction of the channeler tip, or alternatively, the width (corresponding to the base) of the tip blade may gradually decrease or increase along the longitudinal direction of the tip of the channeler As shown in FIG.

A plurality of the tip blades 140 may be spaced apart from each other along the circumferential direction of the channeler tip 130. The number and spacing of the tip blades 140 may be appropriately determined according to the required conditions and the characteristics of the patient can be changed.

2 and 3, when the bone to be treated is exposed to the outside of the tendon, three or four tip blades 140 are spaced apart at equal intervals along the circumferential direction of the channeler tip 130 Can be used. That is, when the bones to be treated are exposed to the outside of the tendon, there is little possibility that the surrounding tendons are damaged by the tip blades 140, so that it is possible to use a relatively large number of tip blades 140 arranged in all directions, In some cases, it is possible to use more than five tip blades.

In another example, referring to FIG. 4, when the bone to be treated is covered by tendons, two tip blades 140 may be used so as to be collinearly arranged along the radial direction of the channeler tip 130. That is, when the bones to be treated are covered by the tendons, the tip blades 140 may damage the tendons of the treatment area, so that the tip blades 140 are provided with a structure that can prevent damage of the tendons Should be able to. In contrast, according to the present invention, two tip blades 140 are arranged on the same line along the radial direction of the channeler tip 130, and two tip blades 140 arranged on the same line are arranged side by side along the lines of the tendons By being able to enter the bone in a deployed state, damage of surrounding tendons can be prevented during the procedure. Of course, although it is possible to use only one tip blade 140, it is difficult for a single tip blade 140 to secure a sufficient peripheral channel.

In the above-described embodiment of the present invention, although the channeler tip is described as being arranged in a straight line along the longitudinal direction of the channel rod, in some cases, the channeler tip may be disposed obliquely with respect to the longitudinal direction of the channel rod It is possible.

Referring to FIG. 5, the channeler tip 130 may be inclined with respect to the longitudinal direction of the channel rod 120. When the channeler tip 130 is inclined with respect to the channel rod 120, it is possible for the channeler tip 130 to enter from the other direction according to the part to be treated. The angle of inclination θ of the channeler tip 130 with respect to the channel rod 120 is preferably less than 20 degrees so as to prevent the channeler tip 130 from being broken from the channeler rod 120 during hammering .

6 is a diagram for explaining an example of use of the channeling apparatus 100 according to the present invention. In addition, the same or equivalent portions as those in the above-described configuration are denoted by the same or equivalent reference numerals, and a detailed description thereof will be omitted.

Referring to FIG. 6, the channeling device according to the present invention forms a main channel A and a peripheral channel B to allow the bone marrow inside the bone to flow well to the site can do.

More specifically, the main channel A having a substantially circular cross-sectional shape can be formed by the channeler tip 130 described above, and the periphery of the main channel A is formed with the tip blade 140 in a substantially triangular shape The main channel A and the peripheral channel B may be connected to each other to form a substantially star-shaped channel. Particularly, since the peripheral channel (B) can be formed around the main channel (A) without increasing the diameter of the main channel itself, fluidity of the marrow can be secured without reducing the structural strength of the bone.

Although the present invention has been described with reference to the preferred embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the following claims. It can be understood that
