Description

Technical Field

[0001] The present invention relates to a thread inserter including a medical thread. More specifically, it can fix the thread to a needle or cannula without performing heat treatment, prevent deformation and breakage of the thread due to heat treatment, enhance the safety of the operation, and can stably fix the end of the thread to the needle without a knot, so that a foreign body sensation caused by the knot of the thread can be prevented. The present invention relates to a thread inserter including a medical thread.

Background Art

[0002] In recent years, as the interest in skin beauty has been increasing, a thread-embedding therapy using a medical thread to improve skin sagging and wrinkles has been developed and widely used.

[0003] The medical thread inserted through the thread-embedding therapy stimulates and pulls the surrounding skin tissue to strengthen the muscles, or has the effect of improving skin sagging and wrinkles, and is absorbed by the treated skin over time.

[0004] In addition, the thread inserter used for such thread-embedding therapy basically extends long in the front-rear direction, and at the rear end, it includes a pipe-shaped insertion needle provided with a handle, and a thread having one end inserted inside the insertion needle and the other end exposed outside and extending rearward.

[0005] When the thread inserter pierces the insertion needle into the human body, the thread is drawn into the human body by the insertion needle. When the insertion needle is pulled out of the human body with the thread reaching the desired part inside the human body, only the thread remains inside the human body. The thread remaining inside the human body in this way stimulates and pulls the tissues inside the human body, strengthening the muscles or having the effect of improving skin sagging and wrinkles.

[0006] On the other hand, with conventional thread inserters, the procedure is prepared by winding medical thread around the outer surface of the insertion needle and fixing both ends to the needle. In this case, a method was used in which knots were made on one side and the other side of the insertion needle to secure the medical thread to the needle.

[0007] However, when medical sutures are tied and secured in this way, the knot protrudes more noticeably than the wound-up suture, causing it to catch when inserting the needle into the skin for the procedure. This results in a foreign body sensation for the patient during the procedure, causing discomfort.

[0008] Furthermore, conventionally, in order to solve the aforementioned problems, a method was used in which medical thread was heat-fused to the insertion needle through heat treatment to fix it in place.

[0009] However, this heat treatment method weakens the physical strength of the thread by applying heat, leading to problems such as changes in the thread's shape or breakage during the procedure. This reduces the safety of the procedure and increases the risk of side effects afterward, highlighting the need for fundamental countermeasures. [Overview of the project] [Problems that the invention aims to solve]

[0010] The object of the present invention is to solve these problems and to provide a thread insertion device that includes a medical thread, which can fix the thread to a needle or cannula without heat treatment, prevents deformation and breakage of the thread due to heat treatment, thereby improving the safety of the procedure, and allows the end of the thread to be stably fixed to the needle without knots, thus preventing the foreign body sensation caused by knots in the thread. [Means for solving the problem]

[0011] A thread inserter including a medical thread according to one embodiment of the technical concept of the present invention for achieving the above objectives may include: an insertion needle inserted into the skin of a patient and having a slit formed on one side of its outer circumference so as to extend longitudinally; a medical thread wound around the outer circumference of the insertion needle and with both ends inserted and fixed into the slit; a handle into which one end of the insertion needle is inserted for the user to grasp with their hand; and a sliding member inserted into the insertion needle adjacent to the handle and sliding on the insertion needle.

[0012] Furthermore, the insertion needle may be in the form of a needle with a sharply formed tip or a cannula with a rounded tip.

[0013] Furthermore, the insertion needle may include a body in the shape of a rod or tube, a slit formed by a groove extending longitudinally on one side of the outer surface of the body, and an opening at the front end of the slit, which is cut so that a part of the body is open, allowing the medical thread wound around the insertion needle to unravel and be pulled out when inserted into the skin of the person being treated.

[0014] Furthermore, the slit may include a first slit in which a groove is cut in a straight line from the front to the rear of the main body, and a second slit connected to the first slit and formed by bending.

[0015] Furthermore, the open portion may be provided with an inclined surface on one side of the open portion.

[0016] Furthermore, the inclined surface may be formed to be inclined upward toward the front.

[0017] Furthermore, the slit may have an inclined portion formed at the front end and a vertical portion formed at the rear end.

[0018] Furthermore, the sliding member may include an insertion tube inserted into the outer circumferential surface of the main body, and a gripping portion sandwiched between the outer circumferential surfaces of the insertion tube and sliding together with the insertion tube on the outer circumferential surface of the insertion needle.

[0019] Further, the insertion tube and the gripping portion may be configured in an integral structure that is not separable.

[0020] Also, the handle may be configured such that its outer peripheral surface is angled and formed with multi-step steps so that the user can easily grip it.

[0021] Further, the gripping portion may be provided with a plurality of gripping protrusions that extend in an outward direction from the outer peripheral surface along the outer peripheral surface so that the user can easily grip it.

Modes for Carrying Out the Invention

[0027] To fully understand the present invention, its operational advantages, and the objectives achieved by implementing the present invention, one must refer to the accompanying drawings illustrating preferred embodiments of the present invention and the contents described in the drawings.

[0028] The present invention will be described in detail below by referring to preferred embodiments of the present invention with reference to the attached drawings. The same reference numerals shown in each drawing indicate the same component.

[0029] The present invention relates to a thread inserter containing a medical thread, which can fix the thread to a needle without heat treatment, thereby preventing deformation and breakage of the thread due to heat treatment, thereby enhancing the safety of the procedure, and can stably fix the end of the thread to the needle without knots, thus preventing the foreign body sensation caused by knots in the thread.

[0030] Figure 1 is a perspective view of a thread inserter containing a medical thread according to one embodiment of the present invention, Figure 2 is an exploded perspective view of a thread inserter containing a medical thread according to one embodiment of the present invention, and Figure 3 is a cross-sectional view of a thread inserter containing a medical thread according to one embodiment of the present invention.

[0031] Referring to Figures 1 to 3, a thread inserter containing medical thread according to one embodiment of the present invention may broadly include an insertion needle 100, medical thread 200, a handle 300, and a sliding member 400.

[0032] First, the insertion needle 100 is in the shape of a long, thin rod or tube, and is the part that is inserted into the patient's skin during thread implantation therapy.

[0033] The insertion needle 100 may be in the shape of a needle with a sharp tip or a cannula with a rounded tip.

[0034] On the other hand, the insertion needle 100 may have a slit 120 formed on one side of its outer surface so as to extend in the longitudinal direction.

[0035] The insertion needle 100 may include a main body 110 in the shape of a rod or tube, a slit 120 formed by a longitudinally extending groove on one side of the outer surface of the main body 110, and an opening 130 at the front end of the slit 120, which is cut so as to open a part of the main body 110, allowing the medical thread 200 wound around the insertion needle 100 to be unraveled and pulled out when inserted into the skin of the person being treated.

[0036] The slit 120 is a groove that extends longitudinally so that one side of the outer circumferential surface of the main body 110 penetrates to the interior, and the width of the groove may be the same as or smaller than the diameter of the medical thread 200.

[0037] On the other hand, the open portion 130 may be provided with an inclined surface 131 on one side of the open portion.

[0038] In this case, the inclined surface 131 may be formed to be inclined upward toward the front.

[0039] In other words, after the main body 110 is inserted into the skin of the person being treated during the procedure, the medical thread 200 wound around the main body 110 is formed to be inclined upward toward the front end so that it can be unwound smoothly without snagging.

[0040] Therefore, the opening 130 is opened to a length greater than that of at least two turns of the medical thread 200 being wound, allowing the leading end of the medical thread 200 to unravel smoothly and sequentially.

[0041] On the other hand, the slit 120 may have an inclined portion 121 formed at the front end and a vertical portion 122 formed at the rear end.

[0042] In other words, the inclined portion 121 is formed to have a large open area so that one end of the medical thread 200 can be easily pulled out during the procedure when it is inserted inside the front part of the slit 120, and the vertical portion 122 is formed to be vertically cut so that the other end of the medical thread 200 can be inserted inside the rear part of the slit 120 and remain fixed for a certain period of time without unraveling before the medical thread 200 at the front, and so that it cannot be easily pulled out.

[0043] Therefore, the medical thread 200 wound on the main body 110 may have a structure that allows it to be fixed in the skin sequentially from the front and then unravel, with the rear end being the last to unravel.

[0044] Next, the medical thread 200 is wound around the outer surface of the insertion needle 100, with both ends inserted and fixed into the slit 120. It is inserted into the patient's skin through thread implantation therapy to stimulate and pull the surrounding skin tissue to strengthen muscles or to improve skin laxity and wrinkles.

[0045] The aforementioned medical thread 200 may be made of a biodegradable polymer that can be broken down and disappear by hydrolysis.

[0046] Furthermore, although not specifically shown in the drawings, the medical thread 200 may have a shape in which thorns or protrusions protrude from its outer surface.

[0047] In other words, when the medical thread 200 is inserted into the skin of the person receiving treatment, it can catch on the skin tissue due to its barbs or protrusions.

[0048] Next, the handle 300 is the part into which one end of the insertion needle 100 is inserted and which the user grasps with their hand.

[0049] The handle 300 is preferably configured such that its outer surface is angular and has multiple steps, allowing the user to easily grip it.

[0050] In other words, the user holds the handle 300 with one hand while performing the procedure, and this is to prevent the handle 300 from easily slipping or falling during this time.

[0051] Furthermore, the shape of the outer surface of the handle 300 is not limited and can consist of various shapes, including angular shapes and multi-tiered shapes.

[0052] Finally, the sliding member 400 is a part that is inserted into the insertion needle 100 adjacent to the handle 300 and slides along the insertion needle 100.

[0053] The sliding member 400 may include an insertion tube 410 inserted into the outer circumferential surface of the main body 110 and a gripping portion 420 that is sandwiched between the outer circumferential surfaces of the insertion tube 410 and slides together with the insertion tube 410 on the outer circumferential surface of the insertion needle 100.

[0054] In this case, the insertion tube 410 and the gripping portion 420 may be constructed in a way that allows them to be separated from each other and fastened together, or the insertion tube 410 and the gripping portion 420 may be constructed in a way that allows them to be separated and are an integrated unit.

[0055] On the other hand, the gripping portion 420 may be provided with a plurality of gripping protrusions 421 that are formed along the outer circumferential surface and extend outward from the outer circumferential surface, so that the user can easily grip it.

[0056] The aforementioned sliding member 400 is inserted into the main body 110 of the insertion needle 100 and is a part that fixes the medical thread 200 in place so that it is not pulled out to the outside of the skin when the main body 110 is pulled backward after it has been inserted into the skin of the person being treated.

[0057] In other words, after inserting the insertion needle 100 into the patient's skin, one hand grasps the gripping portion 420 of the slide member 400, and the other hand grasps the handle 300. While pulling the handle 300 backward, the slide member 400 is fixed in place. As a result, the medical thread 200 wound on the main body 110 is pulled out from the main body 110 and spreads out. Finally, it is caught by the slide member 400 adjacent to the skin and fixed in place, inserted within the skin without being pulled out to the outside.

[0058] Therefore, the insertion tube 410 of the slide member 400 is formed to have a diameter as close as possible to the diameter of the outer surface of the main body 110 so that it can slide freely on the outer surface of the main body 110, and the medical thread 200 wound on the main body 110 can be formed to catch on it.

[0059] Figure 4 is a perspective view of the main body according to another embodiment of the present invention.

[0060] Referring to Figure 4, in another embodiment, the slit 120 may include a first slit 120a in which a groove is cut in a straight line from the front to the rear of the main body 110, and a second slit 120b connected to the first slit 120a and formed by bending.

[0061] In other words, one end of the medical thread 200 wound on the main body 110 can be inserted into the first slit 120a at the front end of the main body 110, and the other end can be inserted into the second slit 120b at the rear end of the main body 110.

[0062] For example, the medical thread 200 can be wound around the outer surface of the main body 110 so as to enclose the first slit 120a, with the other end being sandwiched and fixed in place by the second slit 120b.

[0063] This design allows the other end of the medical thread 200 wound on the main body 110 to be caught in the second slit 120b, which is a groove formed by folding, so that it can be easily unraveled while remaining fixed without separating. After the other end of the medical thread 200 is inserted into the second slit 120b, it becomes caught in the folded groove and cannot be easily pulled out, ultimately preventing the medical thread 200 from unraveling unnecessarily. However, if the medical thread 200 needs to be unraveled in the final stage of the procedure by retracting the main body 110, it can be pulled forward along the inclined, folded groove.

[0064] The thread inserter containing medical thread based on the technical concept of this invention allows the thread to be fixed to a needle or cannula without heat treatment, preventing deformation and breakage of the thread due to heat treatment and thereby enhancing the safety of the procedure. Furthermore, it eliminates restrictions on the material of the thread used in the procedure, and since the end of the thread can be stably fixed to the needle or cannula without knots, it eliminates the feeling of a foreign body caused by knots in the thread, thereby reducing patient discomfort and providing a high level of satisfaction.

Certain terms are used here solely for the purpose of illustrating the invention and not to limit its meaning or the scope of the invention as described in the claims.
