Description

Technical Field

[0005] ,

[0001] The present invention relates to a surgical needle instrument, and more particularly to a needle instrument for orbital fat rearrangement surgery that spreads a part of the orbital fat according to the distribution of the orbital fat and relocates it to the sunken lacrimal sac groove under the eyes.

Background Art

[0002] Generally, as people age, if the orbital septum that surrounds the fat under the lower eyelid becomes weak, the fat in the orbital septum will bulge downwards under the eyes. tt fall rato out and sag. As a result, shadows are cast along the skeletal structure on the side of the nose, or dark circles (dark circles) may appear under the eyes with pigment deposition on the skin, and the skin may sag and wrinkle, making the face look tired. Thus, the accumulation of fat under the eyes is known as a kind of aging phenomenon, and it may also be accompanied by diseases such as hyperthyroidism, renal insufficiency, rhinitis, and asthma.

[0003] Once orbital fat occurs, it is difficult to remove it by methods such as massage or meridians and will not naturally recover to its original state. Therefore, it is necessary to surgically remove and correct the orbital fat in plastic surgery or the like. The surgery to reduce the wrinkles under the eyes while removing the orbital fat is called lower eyelid surgery. However, when making an incision under the eyebrows for the surgery, bruises often occur around the surgical site, and the tear sac disappears, making the face look puffy, and there are problems such as complications like ectropion or blepharoptosis.

[0004] Recently, instead of completely removing the fat under the eyes, an orbital fat rearrangement surgery has been performed to solve dark circles and minimize the depression of the orbit by removing some unnecessary fat according to the distribution of the orbital fat and relocating the remaining part to the sunken lacrimal sac groove under the eyes.

[0005] Conventional techniques for orbital fat repositioning surgery include a skin incision method, which involves making an incision in the skin below the eye, and a conjunctival incision method, which involves making an incision in the conjunctiva inside the eye. However, if the skin sagging is not severe, the conjunctival incision method is preferred because the scar is not very visible from the outside.

[0006] When performing this type of conjunctival incision procedure, tt Ku rato There are two methods for repositioning and fixing protruding orbital fat into the lacrimal sulcus: external fixation and internal fixation.

[0007] The external fixation method involves tying the orbital fat with sutures, then using a needle to pull it out laterally, securing the removed sutures with tape, and maintaining this for approximately one week to induce natural adhesion of the moved fat. The internal fixation method involves fixing the orbital fat from the inside with sutures in the area below the detached lacrimal sulcus groove.

[0008] External fixation methods have the advantage of being easy to perform because they pass through the conjunctiva, and they allow for sufficient movement of orbital fat to the space below the detached area. However, they require taping, the patient must return to the clinic within a week after surgery to have the sutures removed, and there are problems such as skin problems and inflammation caused by the sutures and taping that penetrate the skin.

[0009] Internal fixation methods offer advantages over external fixation methods, including greater stability, fewer recurrences, and the elimination of patient visits for tape and suture removal. However, the limited field of view during conjunctival incision makes internal fixation difficult. To maintain a clear field of view, the incision must be made longer, which can lead to severe conjunctival scarring and adhesions. Furthermore, the narrow surgical space prevents sufficient orbital fat from descending into the lacrimal sulcus, resulting in reduced surgical effectiveness.

[0010] Furthermore, as prior art related to this, Patent Document 1 discloses a reconstructive surgery needle equipped with reconstructive surgical sutures. [Prior art documents] [Patent Documents]

[Modes for carrying out the invention]

[0022] The following describes in detail, with reference to the drawings, the specific details of how to implement the needle instrument for orbital fat repositioning surgery according to this invention, focusing on examples. The needle instrument 10 for orbital fat repositioning surgery according to this invention is used to fix the orbital fat when spreading a portion of the orbital fat according to its distribution and repositioning it downward into the recessed lacrimal sac groove below the eye, and is circular (c i It has an arc shape having a size of 3 / 8 of a rcle and includes a body portion 100, a needle portion 200, and a thread joining portion 300.

[0023] The body portion 100 is the part that is grabbed and used with a needle holder, which is a tool for gripping needles during surgery, and it is preferable that it has a square cross-section and is somewhat elongated vertically.

[0024] Thus, because the body portion 100 has a square cross-section, it allows for an easier and more secure grip on the needle compared to a circular cross-section, preventing the practitioner from dropping the needle instrument and increasing the stability of the procedure. Furthermore, even when a through hole 310 is made in the thread joining portion 300, the durability of the needle is maintained, and there are advantages to easier work when compressing with a press machine.

[0025] The needle portion 200 is formed on both sides of the body portion 100, with one end 210 and the other end 220 extending outwards so that they gradually become sharper towards the ends. It functions as a needle to penetrate and extract fat and skin under the eye. Unlike conventional designs where the needle is formed at only one end, the needle is formed at both ends. This allows for easier internal fixation of fat under the eye even with a limited field of view when approaching the interior through the conjunctiva, minimizing the incision of the conjunctiva, increasing the reliability of downward fixation to orbital fat, and resulting in superior fixation strength.

[0026] In this case, as shown in Figures 2a to 2c as one embodiment, the ends of one piece 210 and the other piece 220 are made of round tips, and the round tip of one piece 210 is formed to be more blunt than the round tip of the other piece 220.

[0027] This is because the round tip of the other side 220, which must penetrate the skin 6, is made sharper than the other side 210 to make it easier for the needle instrument 10 to penetrate the skin, while the round tip of the other side 210, which penetrates into the subcutaneous tissue 7, is made blunter than the other side 220 to prevent the needle instrument 10 from rotating inside the subcutaneous tissue 7 or coming out of the subcutaneous tissue 7. or vinegar ru At the same time, damage to blood vessels and nerves within the subcutaneous tissue 7 can be minimized, and the eyeball 8 in contact with the conjunctiva 3 can be protected to the maximum extent.

[0028] The thread joining portion 300 is formed only at one end of the body portion 100 and not at the other end, to which the thread 320 is joined. As an example, as shown in Figures 2a to 2c, the thread joining type is manufactured with a through hole 310 passing through the thread joining portion 300, and then the practitioner can use it by connecting the thread 320 to the through hole 310. As another example, as shown in Figures 3a to 3c, the thread joining portion 300 is formed with a through hole 310 passing through it, and with the thread passed through the through hole 310, both sides of the body portion 100 are compressed with a press machine to manufacture a thread-attached type in which the thread is attached to the thread joining portion 300, which can then be conveniently used by the practitioner. In this thread-attached type, the entire surface of the body 100, not just the thread connection part 300, is compressed with a press. This is because if only the thread connection part 300, formed by the through-hole 310, is compressed, the thickness of the thread connection part 300 becomes thinner, reducing the strength and durability of the needle instrument 10, which may cause it to break during treatment. In the thread-attached type, the cross-section of the body 100 is closer to a square than in the thread-connected type.

[0029] In this case, it is desirable that the thread connection portion 300 be formed at the position closest to one of the pieces 210. For example, it may be formed at a distance of 1 / 5 to 1 / 6 of the total arc length from one end of the needle instrument 10, and 0.5 to 1 mm away from the interface between the one piece 210 and the body portion 100 toward the body portion 100. This is because if the thread connection portion 300 is formed on one of the pieces 210, the strength of the needle instrument may be weakened and the needle may break during treatment. The closer the thread connection portion 300 is formed to the center of the body portion 100, the more the thread connection portion 300 will be visible toward the skin 6 when the needle instrument 10 is withdrawn toward the skin 6 so that the other piece 220 is not visible from the direction of the conjunctiva 3. of It gets very close, or penetrates the skin. Tattarisu In such cases, dimples, a phenomenon where the skin surface becomes uneven, may occur after the procedure.

[0030] On the other hand, referring to Figures 4a to 4c, the needle portion 200 has a round tip at the end of one side 210, and the other side 220 is generally round in shape, but has a triangular-shaped tip at the end to facilitate skin penetration, with the end of the other side 220 being about 1 to 2 mm in size from the tip.

[0031] The triangularly cut tip at the end of the other piece 220, which must penetrate the skin 6, facilitates the skin penetration of the needle instrument 10, while the blunt round tip of the other piece 210, which penetrates into the subcutaneous tissue 7, prevents the needle instrument 10 from rotating within the subcutaneous tissue 7 or coming out of the subcutaneous tissue 7. hand Next Tarisu At that time, damage to blood vessels and nerves in the subcutaneous tissue 7 can be minimized, and the eyeball 8 in contact with the conjunctiva 3 can be protected to the maximum extent.

[0032] As an example, the thread connection portion 300 is manufactured as a thread-connected type, as shown in Figures 4a to 4c, with a through-hole 310 passing through it, and then the practitioner can connect the thread 320 to the through-hole 310 for use. As another example, as shown in Figures 5a to 5c, the thread connection portion 300 is formed with a through-hole 310 passing through it, and both sides of the body portion 100 are compressed with a press machine with the thread passed through the through-hole 310 to manufacture a thread-attached type in which the thread is attached to the thread connection portion 300, which can then be conveniently used by the practitioner. In this actual-attached type, the entire body portion 100, not just the thread connection portion 300, is compressed with a press machine because if only the thread connection portion 300 formed with the through-hole 310 is compressed, the thickness of only the thread connection portion 300 will decrease, reducing the strength and durability of the needle instrument 10 and potentially causing it to break during treatment. In the thread-attached type, the cross-section of the body portion 100 is closer to a square than in the thread-connected type.

[0033] The surgical process using the needle instrument 10 according to this invention will be explained below with reference to Figures 6a to 7f.

[0034] Using an electrosurgical scalpel or laser, the conjunctiva 3 on the inside of the lower eyelid 2 is made to the minimum extent possible, and as shown in Figure 6a, the needle instrument 10 of this invention is inserted downward through the incised conjunctiva 3, so that the needle instrument 10 and the orbital fat 4 are connected by sutures. When the needle instrument 10 reaches the lacrimal sac groove 5 on the lower side of the orbit 1, the other end 220 of the needle instrument 10 is exposed to the outside by penetrating the subcutaneous tissue 7 and skin 6 outside the lacrimal sac groove 5, while the other end 210, together with the sutures 320, penetrates into the subcutaneous tissue 7.

[0035] At this time, after rotating or moving the needle instrument 10 externally as shown in Figure 6b, and then removing the needle instrument 10 from the subcutaneous tissue 7 from one end 210 as shown in Figure 6c and pulling the needle instrument 10 upward, the thread 320 will become caught in the subcutaneous tissue 7 as shown in Figure 6d. This is possible because the body portion 100 is arc-shaped and has pointed needle portions 200 formed on both sides.

[0036] To explain this process in more detail with an example, as shown in Figures 7a and 7b, the other end 220 of the needle instrument 10 is inserted into the subcutaneous tissue 7, and as shown in Figure 7c, the other end 220 is brought out to the outside of the skin 6. Once one end 210 is completely embedded in the subcutaneous tissue 7, as shown in Figure 7d, the direction of the needle instrument 10 is changed externally, and as shown in Figure 7e, the needle instrument 10 is pushed inward and then withdrawn, causing the thread 320 to catch in the subcutaneous tissue 7, as shown in Figure 7f.

[0037] Subsequently, a portion of the orbital fat 4 is pulled downwards and repositioned into the recessed lacrimal sac groove 5. When the suture 320 is tied, the repositioned orbital fat 4 is fixed in place by the suture 320 caught within the subcutaneous tissue 7. This makes internal fixation of the orbital fat easier, and the orbital fat descends sufficiently into the lacrimal sac groove and is repositioned, increasing the effectiveness of the procedure and resulting in superior fixation strength, which virtually eliminates recurrence.

[0038] Thus, when the surgery is completed using the needle instrument 10 according to the present invention, the dark circles under the eyes are resolved as shown in Figure 8, and the fat under the eyes is repositioned so that the volume under the eyes is restored over a sufficient area from the protruding lacrimal sac groove in the orbit to the cheekbone, resulting in a natural, youthful appearance.

[0039] In short, the orbital fat repositioning surgical needle instrument 10 according to this invention minimizes conjunctival incision on the inside of the eye and reduces conjunctival scarring by using an instrument with an arc shape and needle portions with mutually different shapes at both ends, facilitates internal fixation, increases surgical effectiveness as the orbital fat descends sufficiently to the lacrimal sac groove and is repositioned, enables firm internal fixation and minimizes the possibility of recurrence, prevents postoperative skin damage and dimple phenomenon where the skin surface becomes uneven, and allows for a firm grip with a needle holder, maintaining the strength of the needle, preventing the surgeon from dropping or breaking the needle during the procedure. things like This method increases surgical stability and needle durability, prevents patient inconvenience caused by taping, eliminates the need for patients to visit the clinic to remove the tape and sutures, and prevents skin problems and inflammation caused by sutures and tape penetrating the skin.

[0040] The embodiments described above are illustrative examples, and the present invention is not limited thereto. Any configuration that is substantially identical to the technical idea described in the claims of the present invention and produces the same effects is included within the technical scope of the present invention.
