Description

Meniscus suture device and suture for meniscus suture device

[0001] The present invention relates to a meniscus suturing device and a suture for a meniscus suturing device.

[0002] The meniscus is a crescent-shaped fibrous cartilage located on the medial and lateral sides of the knee joint. This structure fills the void on the outer side when the rounded femur and flat tibia meet to form the knee joint. It serves to absorb shock applied to the knee to reduce compressive stress, provides joint stability during movement, and reduces friction by acting as a lubricant for the articular cartilage.

[0003] The meniscus can rupture due to aging or trauma. A torn meniscus can cause symptoms such as tenderness in the knee joint, pain during movement, and joint locking. Appropriate treatment is necessary because such damage can impair knee joint function.

[0004] Treatment for a damaged meniscus includes non-surgical and surgical methods. Non-surgical treatments include medication using anti-inflammatory painkillers, physical therapy, and injection therapy. However, since the meniscus often does not heal naturally, surgical treatment is necessary in most cases. Representative surgical methods include arthroscopic resection and repair.

[0005] Arthroscopic meniscectomy is a minimally invasive surgical procedure in which an arthroscope and suture device are inserted through a small incision to repair the damaged meniscus. This method offers the advantages of a shorter post-operative recovery time and minimal scarring due to the small incision. Additionally, the arthroscope allows for direct observation of the inside of the knee, enabling accurate diagnosis of the damaged area. This allows for the effective repair and fixation of the damaged meniscus.

[0006] Conventional technology sutures damaged menisci using suture anchors and suture delivery devices. Specifically, it operates by inserting suture anchors on both sides of the damaged meniscus to secure the sutures. However, conventional technology has a problem in that, due to the use of non-absorbable anchors and sutures, if the anchors are not secured behind the meniscus, they can move within the knee and cause fatal cartilage damage.

[0007] The present invention was created to solve the above-mentioned problems and aims to provide a suture for a meniscal repair device and a meniscal repair device that improve the stability of meniscal repair surgery.

[0008] One embodiment of the present invention provides a suture for a meniscus repair device comprising a flexible suture body having a longitudinally extended shape, a plurality of micro-protrusions formed by protruding at predetermined intervals on the outer surface of the suture body, and a first fixing member provided at one end of the suture body and coupled to the suture body, wherein the suture body, the micro-protrusions, and the first fixing member comprise a bioabsorbable material.

[0009] The suture for a meniscus repair device and the meniscus repair device according to the embodiments of the present invention can improve the stability of meniscus repair surgery.

[0037] One embodiment of the present invention provides a suture for a meniscus repair device comprising a flexible suture body having a longitudinally extended shape, a plurality of micro-protrusions formed by protruding at predetermined intervals on the outer surface of the suture body, and a first fixing member provided at one end of the suture body and coupled to the suture body, wherein the suture body, the micro-protrusions, and the first fixing member comprise a bioabsorbable material.

[0038] In one embodiment of the present invention, the first fixing member may be changeable between a first placement state in which it is received in a suturing device and a second placement state in which it is withdrawn from the suturing device.

[0039] In one embodiment of the present invention, the first fixing member may be formed in a shape that extends in a direction intersecting the longitudinal direction of the suture body in the second arrangement state.

[0040] In one embodiment of the present invention, in the first arrangement state, one end of the first fixing member may be positioned close to the suture body and the other end of the first fixing member may be positioned away from the suture body.

[0041] In one embodiment of the present invention, the center of the first fixing member may be located on the extension line in the longitudinal direction of the suture body.

[0042] In one embodiment of the present invention, the first fixing member may be deformed from a state in which both ends of the first fixing member are folded so that they are adjacent to each other when withdrawn from a suturing device to a state in which both ends of the first fixing member are unfolded.

[0043] In one embodiment of the present invention, the bioabsorbable material may be any one selected from the group consisting of polydioxanone, polylactic acid, polycaprolactone, polyhydroxybutyrate, and polyglycolic acid.

[0044] In one embodiment of the present invention, the micro-protrusions may be arranged on both sides of the suture body facing each other with respect to the suture body.

[0045] In one embodiment of the present invention, the micro-protrusions may allow the suture to move from the distal end toward the proximal end when the suture is in the tissue, but may restrict movement in the opposite direction.

[0046] In one embodiment of the present invention, the micro-protrusion may include an inclined surface formed such that the height of the distal side where the first fixing member is formed is higher than the height of the proximal side closer to the other end of the suture body.

[0047] In one embodiment of the present invention, a second fixing member movable along the longitudinal direction of the suture body toward the first fixing member may be further included.

[0048] In one embodiment of the present invention, the second fixing member may be movable from the proximal portion of the suture toward the distal portion, but movement in the opposite direction may be restricted.

[0049] In one embodiment of the present invention, when a suture is in the tissue, the second fixing member may be positioned corresponding to the first fixing member so that the tissue is located between the first fixing member and the second fixing member.

[0050] In one embodiment of the present invention, the second fixing member includes a hollow corresponding to the longitudinal direction of the suture body, and the suture body can be inserted through the hollow.

[0051] In one embodiment of the present invention, the second fixing member may have an uneven surface protruding on the inner surface of the hollow in correspondence with the fine protrusion.

[0052] In one embodiment of the present invention, the uneven surface may include an inclined surface formed such that the height of the proximal side is higher than that of the distal side.

[0053] One embodiment of the present invention provides a meniscal suture device comprising: a surgical suture; a tubular receiving portion that receives at least a portion of the surgical suture; a pulling member that is movable along the longitudinal direction within the receiving portion and is for pulling out the surgical suture; and a controlling portion that is coupled to one end of the receiving portion and controls the operation of the pulling member. The surgical suture comprises a flexible suture body that is extended in the longitudinal direction; a plurality of micro-protrusions formed by protruding at predetermined intervals on the outer surface of the suture body; and a first fixing member provided at one end of the suture body and coupled to the suture body. The suture body, the micro-protrusions, and the first fixing member comprise a bioabsorbable material.

[0054] In one embodiment of the present invention, the operating member may include a main body, a lever coupled to the main body and rotatable about a first axis, and a support member to which the proximal end of the extraction member is fixedly coupled.

[0069]

[0070] Conventionally, a suturing device equipped with a suture anchor and a delivery device for delivering suture thread was used to repair a damaged meniscus. When performing meniscus repair surgery, the operator accesses the inside of the knee joint through an arthroscope and inserts the suturing device through a small incision. Then, a needle with an anchor attached is inserted and penetrated through the meniscus, and the anchor is ejected through the opposite side. The suturing device according to the prior art has a problem in that, because it uses non-absorbable suture thread and a suture anchor, if the suture anchor is not accurately fixed to the outer side of the meniscus, the anchor moves inside the patient's knee and causes severe cartilage damage.

[0071] The suture thread and suture device according to an embodiment of the present invention are intended to solve the aforementioned problem and can improve the stability of meniscal repair surgery.

[0072] Hereinafter, a suture for a meniscus suturing device according to one embodiment of the present invention will be described.

[0073] FIGS. 1 and FIGS. 2 are perspective views showing a suture for a meniscal repair device according to one embodiment of the present invention, and FIG. 3 is a plan view showing the suture for a meniscal repair device of FIG. 1. FIG. 4 is a side view showing the suture for a meniscal repair device of FIG. 1, and FIG. 5 is a cross-sectional view showing one cross section of the suture for a meniscal repair device of FIG. 1.

[0074] Referring to FIGS. 1 to 5, a suture (100) for a meniscal suturing device according to one embodiment of the present invention may include a suture body (110), a micro-protrusion (130), and a first fixing member (120).

[0075] The suture body (110) may be flexible and have a shape that extends in the longitudinal direction. For example, the suture body (110) may be in the shape of a long cylindrical thread. However, the cross-sectional shape of the suture body (110) is not necessarily limited thereto and may include polygons such as elliptical, triangular, square, trapezoidal, and pentagonal shapes.

[0076] According to one embodiment of the present invention, the diameter of the suture (100) may be in the range of about 0.001 mm to about 1 mm. The length of the suture (100) may be about 1 cm to about 50 cm. Preferably, the length of the suture (100) may be in the range of about 2 cm to about 22 cm.

[0077] In addition, fine protrusions may be formed on the outer surface of the suture body (110).

[0078] Specifically, the micro-protrusions (130) can be formed by protruding at predetermined intervals on the outer surface of the suture body (110).

[0079] The micro-protrusions (130) can be arranged facing each other on both sides with respect to the suture body (110) as shown in the drawing. To explain this from another perspective, when the micro-protrusions (130) are arranged on a virtual plane perpendicular to the longitudinal axis of the suture body (110), the micro-protrusions (130) can be arranged radially at 180 degrees on both sides with the suture body (110) in between.

[0080] However, the concept of the present invention is not limited thereto, and the arrangement of the micro-protrusions (130) can be formed in various ways. For example, a plurality of micro-protrusions (130) may be arranged radially at 120 degrees on the outer surface of the suture body (110). In addition, a plurality of micro-protrusions (130) may be arranged radially at 90 degrees on the outer surface of the suture body (110). In other words, four micro-protrusions (130) may be arranged in a cross shape.

[0081] Additionally, the micro-protrusions (130) may be arranged differently along the longitudinal direction of the suture body (110). For example, a plurality of micro-protrusions (130) arranged from the proximal end (100p) to the distal end (100d) of the suture body (110) may be arranged in a spiral shape. For example, a plurality of micro-protrusions (130) arranged from the proximal end (100p) to the distal end (100d) of the suture body (110) may be arranged in a zigzag shape.

[0082] Additionally, the micro-protrusions (130) may be irregularly arranged along the longitudinal direction of the suture body (110).

[0083] Meanwhile, the micro-protrusion (130) may be formed asymmetrically in correspondence with the longitudinal direction of the suture body (110). That is, the micro-protrusion (130) may be formed so that the protruding shape has a certain directionality.

[0084] Specifically, the micro-protrusion (130) may include an inclined surface formed such that the height of the distal side (100d) where the first fixing member (120) is formed is higher than the height of the proximal side (100p) near the other end of the suture body (110).

[0085] Expressed from another perspective, the micro-protrusion (130) may be shaped such that the distal side (100d) protrudes more from the suture body (110) than the proximal side (100p).

[0086] For example, as shown in FIG. 1, the micro-protrusion (130) can be formed in an arrowhead-like shape.

[0087] The height (H1) of the micro-protrusion (130) may be in the range of about 0.001 mm to about 1 mm.

[0088] The length (L1) of the micro-protrusion (130) may be greater than the height of the micro-protrusion (130). For example, the length (L1) of the micro-protrusion (130) may be in the range of about 0.01 mm to about 3 mm.

[0089] The thickness (T1) of the micro-protrusion (130) may be smaller than or equal to the diameter of the suture body (110).

[0090] The thickness (T1) of the micro-protrusion (130) may vary depending on the height (H1) of the protrusion. That is, the thickness may be formed thinner as it moves further away from the suture body (110).

[0091] A suture (100) for a meniscus suturing device according to one embodiment of the present invention may be restricted from moving in one direction when it is in tissue. Specifically, the suture may be able to move in the direction of the distal portion (100d) where the first fixing member (120) is formed, but may be restricted from moving in the opposite direction.

[0092] In other words, the micro-protrusion (130) can allow the suture to move from the distal portion (100d) toward the proximal portion (100p) when the suture is in the tissue, but can restrict movement in the opposite direction.

[0093] Through this, the suture having micro-protrusions (130) can be easily fixed within the tissue.

[0094] Meanwhile, the first fixing member (120) may be provided at one end of the suture body (110) and may be formed integrally with the suture body (110). Alternatively, the first fixing member (120) may be coupled to one end of the suture body (110) through a connecting member.

[0095] The first fixing member (120) may be formed of a flexible material. The first fixing member (120) may include a material such as a suture body (110).

[0096] The suture body (110), the micro-protrusion (130), and the first fixing member (120) may comprise a bioabsorbable material. Here, the bioabsorbable material may be any one selected from the group consisting of polydioxanone, polylactic acid, polycaprolactone, polyhydroxybutyrate, and polyglycolic acid.

[0097] The center of the first fixing member (120) may be located on the longitudinal extension of the suture body (110). Alternatively, the first fixing member (120) may be formed on one side of the distal portion (100d) of the suture body (110).

[0098] As shown in FIG. 2, the first fixing member (120) can be connected to the suture body (110) so as to be rotatable around the part (111) connected to the suture body (110).

[0099] Specifically, one end (121) of the first fixing member (120) may be positioned close to the suture body (110), and the other end (122) of the first fixing member (120) may be positioned away from the suture body (110).

[0100] For example, the first fixing member (120) may be positioned close to a direction parallel to the suture body (110).

[0101] FIG. 6 is a drawing for explaining the process of a suture for a meniscus suturing device according to one embodiment of the present invention being withdrawn from a suturing device, and FIG. 7 is a drawing for explaining the process of suturing a meniscus using a meniscus suturing device according to one embodiment of the present invention.

[0102] The meniscus suturing device described below includes a receiving portion (210) for receiving a suture, and the receiving portion (210) may be formed in the shape of a long, thin tube. Specifically, the end of the receiving portion (210) may be formed in the shape of a hypodermic needle. Additionally, the meniscus suturing device may further include a tube (230) that surrounds the outer surface of the receiving portion (210). The tube (230) exposes the end of the receiving portion (210) and can protect the portion excluding the end of the receiving portion (210).

[0103] FIG. 6(a) shows a first fixing member (120) in a first placement state with the suture received in the receiving portion (210), FIG. 6(b) shows the first fixing member (120) being withdrawn from the receiving portion (210). FIG. 6(c) shows the first fixing member (120) being placed in a second placement state after being withdrawn from the receiving portion (210).

[0104] Here, as shown in FIG. 1, a state in which the first fixing member (120) is positioned close to perpendicular to the suture body (110) can be defined as a second positioning state, and as shown in FIG. 2, a state in which the first fixing member (120) is positioned close to a direction parallel to the suture body (110) can be defined as a first positioning state.

[0105] Referring to FIG. 6 (a) to (c), the first fixing member (120) may have a change in its position. Specifically, the first fixing member (120) may be changed between a first position in which it is received in a suture device and a second position in which it is withdrawn from the suture device.

[0106] Specifically, in the first arrangement state, one end (121) of the first fixing member (120) may be positioned close to the suture body (110), and the other end (122) of the first fixing member (120) may be positioned away from the suture body (110).

[0107] For example, when the first fixing member (120) is in the first positioning state, the first fixing member (120) may be positioned close to a direction parallel to the suture body (110).

[0108] And the first fixing member (120) can be formed in a shape that extends in a direction intersecting the longitudinal direction of the suture body (110) in the second arrangement state.

[0109] Referring to FIG. 7, a needle-shaped receiving portion (210) can be penetrated into the meniscus (M) to suture the meniscus (M) using a meniscus suturing device according to one embodiment of the present invention. Then, the first fixing member (120) can be pulled out of the receiving portion (210) through a pulling member (220, see FIG. 26). With the first fixing member (120) received within the receiving portion (210) of the suturing device, the first fixing member (120) can be moved along the longitudinal direction of the receiving portion (210) together with the suture body (110).

[0110] Then, after the first fixing member (120) is withdrawn out of the receiving portion (210) together with the suture body (110), the first fixing member (120) can be positioned to intersect with the longitudinal extension line of the suture body (110). That is, the first fixing member (120) can be positioned nearly perpendicular to the penetrating direction of the cartilage plate (M). Thus, even if the suture body (110) can move along the direction penetrating the cartilage plate (M), the suture can no longer move as the first fixing member (120) attached to the end of the suture body (110) gets caught on the cartilage plate (M).

[0111] As such, the suture (100) for a meniscus suturing device according to one embodiment of the present invention includes a micro-protrusion (130) and a first fixing member (120), thereby allowing for easy completion of meniscus suturing, unlike conventional sutures that use a hard anchor or a separate knot.

[0112] FIG. 8 is a diagram illustrating the process of withdrawing a suture according to another embodiment of the present invention.

[0113] Referring to FIG. 8, the shape of the first fixing member (1120) can change. Specifically, as described above, the shape of the first fixing member (1120) can change as it changes from a state in which it is received in the receiving portion (210) of the suture device to a state in which it is pulled out of the receiving portion (210).

[0114] Specifically, when the first fixing member (1120) is withdrawn from the sealing device, the two ends (1121) (1122) of the first fixing member (1120) may be folded so that they are adjacent to each other, and the two ends (1121) (1122) of the first fixing member (1120) may be unfolded.

[0115] In other words, the center of the first fixing member (1120) can be foldable. Thus, the first fixing member (1120) can be placed in the receiving portion (210) in a folded state, and the first fixing member (1120) can be unfolded outside the receiving portion (210) and placed in a direction intersecting the longitudinal extension of the suture body (1110).

[0116] That is, the first fixing member (1120) can be positioned nearly perpendicular to the penetrating direction of the cartilage plate (M). Therefore, even if the suture body (1110) can move along the direction penetrating the cartilage plate (M), the suture can no longer move as the first fixing member (1120) attached to the end of the suture body (1110) gets caught on the cartilage plate (M).

[0117] FIG. 9 is a perspective view showing a suture (2100) for a meniscal plate suturing device according to another embodiment of the present invention separated into a suture body (2110) and a first fixing member (2120), and FIG. 10 is a perspective view showing the suture body (2110) and the first fixing member (2120) combined.

[0118] Referring to FIGS. 9 and 10, a suture (2100) for a meniscal suturing device according to another embodiment of the present invention may include a suture body (2110), a micro-protrusion (2130), and a first fixing member (2120).

[0119] In another embodiment of the present invention, the suture (2100) is characterized by a different configuration of the first fixing member (2120) compared to the suture (100) according to the above embodiment.

[0120] Here, the suture body (2110) and the micro-protrusion (2130) are substantially identical to the suture body (110) and the micro-protrusion (130) of the suture (100) according to the above-described embodiment in terms of their respective corresponding ranges, so a detailed description is omitted.

[0121] The suture body (2110) according to the present embodiment may include a connecting portion (2111) at the distal portion (2100d). Here, the connecting portion (2111) may be a part connected to the first fixing member (2120).

[0122] Specifically, the connecting portion (2111) of the suture body (2110) can be connected to the fastening portion (2122) of the first fixing member (2120) to be described later.

[0123] The connecting portion (2111) may be a ring-shaped part formed by fixing the distal end (2100d) of the suture body (2110) to one side of the suture body (2110).

[0124] Additionally, the connecting portion (2111) may be a part where the fine protrusion (2130) is not formed, as shown in the drawing. However, the concept of the present invention is not limited thereto, and it is obvious that the fine protrusion (2130) may also be formed on the connecting portion (2111).

[0125] The first fixing member (2120) according to the present embodiment may be a separate member formed separately from the suture body (2110). For example, as shown in FIGS. 9 and 10, the first fixing member (2120) may be a member formed separately and coupled to the suture body (2110).

[0126] The first fixing member (2120) according to the present embodiment may include a main fixing part (2121) and a fastening part (2122).

[0127] Here, the main fixing part (2121) may be a longitudinal member made of a flexible material. And the first fixing member (2120) may include a material such as a suture body (2110).

[0128] A fastening portion (2122) may be formed on the main fixing portion (2121). In one embodiment, the fastening portion (2122) may be formed on the side of the main fixing portion (2121). Additionally, the fastening portion (2122) may include a through hole (a1) in the shape of a ring. Furthermore, the connecting portion (2111) of the aforementioned suture body (2110) may pass through the through hole (a1) of the fastening portion (2122).

[0129] Specifically, the distal end (2100d) of the suture body (2110) can be fixed to one side of the suture body (2110) after passing through the through hole (a1) of the fastening part (2122). That is, the suture body (2110) and the first fixing member (2120) can be combined by connecting the ring-shaped fastening part (2122) and the ring-shaped connecting part (2111) to each other like a chain.

[0130] Meanwhile, multiple fastening parts (2122) may be provided. For example, two fastening parts (2122) may be formed spaced apart on one side of the main fixing part (2121).

[0131] In this case, the connecting portion (2111) of the suture body (2110) can be coupled with the first fixing member (2120) by passing through the through hole (a1) of the two fastening portions (2122). That is, the distal end (2100d) of the suture body (2110) can be fixed to one side of the suture body (2110) after passing through the two through holes (a1).

[0132] In another embodiment, the first fixing member (2120) may form a through hole (a1) inside the main fixing part (2121). Then, the distal end (2100d) of the suture body (2110) passes through the through hole (a1) and is fixed to the side of the suture body (2110) to form a loop, thereby allowing the suture body (2110) and the first fixing member (2120) to be combined.

[0133] FIG. 11 is a drawing for explaining the process of withdrawing a suture thread (2100) for a meniscus (M) suturing device of FIG. 10 from the suturing device.

[0134] Referring to FIG. 11, the first fixing member (2120) can be withdrawn from the receiving portion (210) together with the suture body (2110). Specifically, as with the first fixing member (120) of the previously described embodiment, the first fixing member (2120) can be positioned so as to be close to a direction parallel to the suture body (2110) while the first fixing member (2120) is received inside the receiving portion (210). To explain this from another perspective, the main fixing portion (2121) of the first fixing member (2120) can be positioned in a direction corresponding to the longitudinal direction of the receiving portion (210).

[0135] FIG. 12 is a drawing for explaining the process of suturing a meniscus (M) using the meniscus (M) suturing device of FIG. 10.

[0136] In order to suture the cartilage plate (M) using a cartilage plate (M) suturing device according to one embodiment of the present invention, a needle-shaped receiving portion (210) can be penetrated into the cartilage plate (M). Afterward, a first fixing member (2120) can be pulled out of the receiving portion (210) through a pulling member (not shown). While the first fixing member (2120) is received within the receiving portion (210) of the suturing device, the first fixing member (2120) can be moved along the longitudinal direction of the receiving portion (210) together with the suture body (2110).

[0137] And after the first fixing member (2120) is withdrawn out of the receiving portion (210) together with the suture body (2110), the first fixing member (2120) can be positioned to intersect with the longitudinal extension line of the suture body (2110).

[0138] And the main fixing part (2121) of the first fixing member (2120) can be bent. For example, the main fixing part (2121) can be bent so that both ends are closer together with respect to the center between the two fastening parts (2122). In other words, the main fixing part (2121) can be bent into a U-shape.

[0139] Specifically, since the two fastening parts (2122) formed on the main fixing part (2121) are combined with the connecting part (2111) of the suture body (2110), the two fastening parts (2122) can be brought together by the force of the connecting part (2111) pulling the two fastening parts (2122). That is, the two fastening parts (2122) can partially overlap so that the through holes overlap each other. When force is applied to the fastening part (2122) as described above, the main fixing part (2121) to which the fastening part (2122) is combined can be bent so that both ends are brought closer to each other with respect to the center.

[0140] When the suture body (2110) is pulled in the opposite direction to the withdrawal direction, the first fixing member (2120) attached to the end of the suture body (2110) may be caught on the cartilage plate (M). Since the first fixing member (2120) is positioned to intersect with the suture body (2110), it becomes difficult for the first fixing member (2120) to pass through the cartilage plate (M). Additionally, as described above, even if the first fixing member (2120) is bent, it becomes difficult for it to penetrate the cartilage plate (M).

[0141] Therefore, even if the suture body (2110) retracts in the opposite direction to the direction in which it penetrates the cartilage plate (M), if the first fixing member (2120) catches on the cartilage plate (M), the suture can no longer move backward.

[0142] FIGS. 13 and 14 are perspective views showing a suture (3100) for a meniscal suturing device according to another embodiment of the present invention. FIG. 15 is a perspective view showing the suture (3100) of FIG. 13 and a second fixing member (3140).

[0143] Referring to FIGS. 13 and 14, a suture (3100) for a meniscal suturing device according to another embodiment of the present invention may include a suture body (3110), a micro-protrusion (3130), and a first fixing member (3120).

[0144] In another embodiment of the present invention, the suture (3100) is characterized by a different configuration of the first fixing member (3120) compared to the suture (100) according to the above embodiment.

[0145] Here, the suture body (3110) and the micro-protrusion (3130) are substantially identical to the suture body (110) and the micro-protrusion (130) of the suture (100) according to the above-described embodiment in terms of their respective corresponding ranges, so a detailed description is omitted.

[0146] The suture body (3110) according to the present embodiment may include a connecting portion (3111) at the distal portion (3100d). Here, the connecting portion (3111) may be a part connected to the first fixing member (3120).

[0147] The connecting portion (3111) may be a part where the fine protrusion (3130) is not formed, as shown in the drawing. However, the concept of the present invention is not limited thereto, and it is obvious that the fine protrusion (3130) may also be formed on the connecting portion (3111).

[0148] Meanwhile, as illustrated in FIG. 15, a second fixing member (3140) may be attached to the suture body (3110). Here, the second fixing member (3140) may move along the longitudinal direction of the suture body (3110). Since the second fixing member (3140) is substantially identical to the second fixing member (140) described later in a corresponding range, the second fixing member (3140) will be described in detail later.

[0149] Meanwhile, the first fixing member (3120) may be formed integrally with the suture body (3110) at one end of the distal portion (3100d) of the suture body (3110). Specifically, the first fixing member (3120) may be a part connected to the connecting portion (3111) of the suture body (3110). That is, the first fixing member (3120) may be formed integrally with the connecting portion (3111).

[0150] The first fixing member (3120) may be formed of a flexible material. Additionally, the first fixing member (3120) may include a material such as a suture body (3110).

[0151] For example, the first fixing member (3120) may also include a bioabsorbable material. Here, the bioabsorbable material may be any one selected from the group consisting of polydioxanone, polylactic acid, polycaprolactone, polyhydroxybutyrate, and polyglycolic acid.

[0152] The first fixing member (3120) may not include a fine protrusion (3130) as shown in the drawing. However, the concept of the present invention is not limited thereto, and it is obvious that a fine protrusion (3130) may be formed on the first fixing member (3120).

[0153] As illustrated in FIG. 14, the first fixing member (3120) can be connected to the suture body (3110) so as to be rotatable around the connecting part (3111) connected to the suture body (3110).

[0154] The first fixing member (3120) may include a main fixing part (3121) and a fastening part (3122). Here, the main fixing part (3121) is a longitudinal member connected to the connecting part (3111) of the suture body (3110) and may have a cylindrical thread shape such as a suture. However, the cross-sectional shape of the main fixing part (3121) is not limited and may include polygons such as elliptical, triangular, square, trapezoidal, and pentagonal shapes.

[0155] The main fixing part (3121) can be positioned in a direction that intersects the longitudinal direction of the suture body (3110). That is, the main fixing part (3121) can be formed in a shape that is bent at a certain angle relative to the suture body (3110).

[0156] And as described above, the main fixing part (3121) may be rotatable around the connecting part (3111) of the suture body (3110). To explain this from another perspective, the angle between the main fixing part (3121) and the suture body (3110) may be variable.

[0157] Meanwhile, a fastening part (3122) may be formed on the main fixing part (3121). In one embodiment, the fastening part (3122) may be formed on the side of the main fixing part (3121). This fastening part (3122) may be formed in a ring shape to form a through hole (a3) ​​inside. Alternatively, the fastening part (3122) may be formed in a U-shape and both ends may be connected to the main fixing part (3121), thereby forming a through hole (a3) ​​surrounded by the fastening part (3122) and the main fixing part (3121).

[0158] In another embodiment, the first fixing member (3120) may form a through hole (a3) ​​inside the main fixing part (3121). And the proximal end (3100p) of the suture body (3110) may pass through the through hole (a3).

[0159] Meanwhile, the suture body (3110) can pass through the through hole (a3) ​​of the fastening part (3122). FIG. 14 shows that the proximal end (3100p) of the suture body (3110) is extended by passing through the through hole (a3) ​​of the first fixing member (3120).

[0160] In this way, the suture body (3110) is inserted into the through hole formed by the fastening part (3122), so that the first fixing member (3120) can be positioned adjacent to the suture body (3110). That is, the main fixing part (3121) and the suture body (3110) form a sharp angle, and the main fixing part (3121) can be positioned almost parallel to the longitudinal direction of the suture body (3110).

[0161] FIG. 16 is a drawing for explaining the process of withdrawing the suture thread (3100) for the meniscus suturing device of FIG. 13 from the suturing device.

[0162] Referring to FIG. 16, the first fixing member (3120) can be withdrawn from the receiving portion (210) together with the suture body (3110). Specifically, like the first fixing member (120) of the previously described embodiment, the first fixing member (3120) can be positioned close to a direction parallel to the suture body (3110) while being received inside the receiving portion (210). To explain this from another perspective, the main fixing portion (3121) of the first fixing member (3120) can be positioned in a direction corresponding to the longitudinal direction of the receiving portion (210).

[0163] In this way, since the first fixing member (3120) can be received in the receiving portion (210) in a folded state, the diameter of the receiving portion (210) of the suture device can be minimized to receive the suture thread (3100).

[0164] Figure 17 is a diagram illustrating the process of suturing a meniscus using the suture of Figure 13 together with a meniscus suturing device.

[0165] Referring further to FIG. 17, the first fixing member (3120) can have its position changed. Specifically, the suture (3100) can have its position changed between the first position and the second position, as with the suture (100) of the above-described embodiment.

[0166] In describing the present invention, the first arrangement state is a state in which the first fixing member (3120) is arranged in a direction close to parallel to the suture body (3110) as described above, and the second arrangement state is a state in which the first fixing member (3120) is arranged in a direction intersecting the longitudinal direction of the suture body (3110). For example, as shown in FIG. 17 (b), the first fixing member (3120) may be arranged in a direction perpendicular to the longitudinal direction of the suture body (3110).

[0167] According to the present invention, when the suture (3100) is received in the receiving portion (210) of the suture device, the first fixing member (3120) is positioned in a first position, and when the suture (3100) is withdrawn from the suture device, the first fixing member (3120) can be positioned in a second position.

[0168] Referring to FIG. 17, a needle-shaped receiving portion (210) can be penetrated into the cartilage plate (M) to suture the cartilage plate (M) using a cartilage plate (M) suturing device according to one embodiment of the present invention. Then, the first fixing member (3120) can be pulled out of the receiving portion (210) through a pulling member (220, see FIG. 26). With the first fixing member (3120) received within the receiving portion (210) of the suturing device, the first fixing member (3120) can be moved along the longitudinal direction of the receiving portion (210) together with the suture body (3110).

[0169] And after the first fixing member (3120) is withdrawn out of the receiving portion (210) together with the suture body (3110), the first fixing member (3120) can be positioned to intersect with the longitudinal extension line of the suture body (3110).

[0170] At this time, if the suture body (3110) is pulled in the opposite direction to the withdrawal direction, the first fixing member (3120) attached to the end of the suture body (3110) can be caught on the cartilage plate (M). And since the first fixing member (3120) is positioned to intersect with the suture body (3110), it becomes difficult for the first fixing member (3120) to pass through the cartilage plate (M).

[0171] Therefore, even if the suture body (3110) retracts in the opposite direction to the direction in which it penetrates the cartilage plate (M), if the first fixing member (3120) catches on the cartilage plate (M), the suture (3100) can no longer move backward.

[0172] FIGS. 18 and 19 are drawings for explaining the use of a suture according to another embodiment of the present invention, and FIG. 20 is a perspective view showing a second fixing member (140) of the suture of FIG. 18. FIG. 21 is a cross-sectional perspective view taken along line A-A' of FIG. 20, and FIG. 22 is a cross-sectional view taken along line B-B' of FIG. 20.

[0173] Referring to FIGS. 18 to 22, a suture (100) for a meniscal suturing device according to another embodiment of the present invention may further include a second fixing member (140).

[0174] The second fixing member (140) may be a fixing member movable along the longitudinal direction of the suture body (110) toward the first fixing member (120).

[0175] The second fixing member (140) may include a hollow (142) corresponding to the longitudinal direction of the suture body (110). That is, the second fixing member (140) may be a tubular member with a hollow center. And the suture body (110) may be inserted through the hollow (142) of the second fixing member (140).

[0176] Referring to FIGS. 20 and 21, the second fixing member (140) may have an uneven surface (143) protruding on the inner surface of the hollow (142) in correspondence with the fine protrusion (130).

[0177] Here, the uneven surface (143) may include an inclined surface (143a) formed such that the height of the proximal side is higher than that of the distal side.

[0178] To explain this from another perspective, the inclined surface of the uneven part (143) can correspond to the inclined surface of the fine protrusion (130).

[0179] In the drawing, the uneven surface (143) is formed only on one side of the inner surface of the hollow (142), but the concept of the present invention is not necessarily limited thereto, and the uneven surface (143) can be arranged in various shapes and at various locations on the inner surface of the second fixing member (140).

[0180] For example, the uneven portion (143) may be formed continuously along the circumference of the inner surface of the hollow (142). That is, the uneven portion (143) may be formed in a band shape on the inner surface of the hollow (142).

[0181] As such, when the second fixing member (140) is fastened to the suture body (110) and moves, friction may occur between the uneven portion (143) and the fine protrusion (130) as the uneven portion (143) is formed on the inner surface of the second fixing member (140).

[0182] Accordingly, the second fixing member (140) can move from the proximal part (100p) of the suture toward the distal part (100d), but movement in the opposite direction may be restricted.

[0183] In other words, the second fixing member (140) may be restricted from moving from the proximal part (100p) of the suture body (110) toward the distal part (100d) and then back toward the proximal part (100p) while fastened to the suture body (110).

[0184] As illustrated in FIGS. 18 and 19, a first fixing member (120) is deployed at the distal portion (100d) of the suture that penetrates the cartilage plate (M), and a second fixing member (140) can move along the suture body (110) toward the first fixing member (120).

[0185] In this way, when the suture (100) is in the tissue, the second fixing member (140) may be positioned corresponding to the first fixing member (120) so that the tissue is located between the first fixing member (120) and the second fixing member (140).

[0186] After the second fixing member (140) is moved sufficiently close to the first fixing member (120), the second fixing member (140) may catch on the cartilage plate (M), making further movement difficult. That is, the suture (100) can be fixed with the first fixing member (120) and the second fixing member (140) positioned on both sides of the cartilage plate (M).

[0187] Therefore, the suture (100) cannot move while inserted into the cartilage plate (M), so it can be stably fixed to the cartilage plate (M).

[0188]

[0189] Hereinafter, a meniscus suturing device according to one embodiment of the present invention will be described.

[0190] FIG. 23 is a perspective view showing a meniscus suturing device according to an embodiment of the present invention, and FIG. 24 is a side view showing a meniscus suturing device according to an embodiment of the present invention. FIG. 25 is a drawing showing the state in which the lever (320) of the meniscus suturing device of FIG. 23 is operated, and FIG. 26 is an enlarged view showing part A of FIG. 25 enlarged. FIG. 27 is a drawing showing the interior of the main body (310) of the meniscus suturing device of FIG. 23, and FIG. 28 is a drawing showing the state in which the lever (320) of the meniscus suturing device of FIG. 27 is a drawing showing the receiving portion (210) of the meniscus suturing device of FIG. 23, and FIG. 30 is a drawing showing a withdrawal member (220) received in the receiving portion (210) of the meniscus suturing device of FIG. 23.

[0191] Referring to FIGS. 23 to 30, a meniscus suturing device according to one embodiment of the present invention may include a surgical suture, a receiving portion (210), a pulling member (220), and a manipulating portion (300).

[0192] Here, the surgical suture may be the suture for the meniscus suturing device described above.

[0193] The operating unit (300) is coupled to one end of the receiving unit (210) and can control the operation of the extraction member (220). Here, the operating unit (300) may include a main body (310), a lever (320), and a support member (330).

[0194] A lever (320) and a support member (330) may be coupled to the main body (310), and the main body (310) may be formed so that a user can hold the sealing device with one hand.

[0195] The lever (320) is coupled to the main body (310) and can rotate around a first rotation axis (322). Specifically, the first rotation axis (322) may be formed on the distal side of the main body (310).

[0196] The distal end of the lever (320) is connected to the first rotation axis (322), and the proximal end of the lever (320) can be positioned so as to be spaced apart from the main body (310).

[0197] Meanwhile, a support member (330) may be disposed inside the main body (310). Specifically, the support member (330) may be disposed to move in parallel along the longitudinal direction of the main body (310).

[0198] And the support member (330) may be a part to which the proximal end of the extraction member (220) is fixedly connected.

[0199] Accordingly, the support member (330) moves relative to the main body (310) along the extension direction of the receiving portion (210), and the withdrawal member (220) can advance or retract within the receiving portion (210) by the movement of the support member (330).

[0200] Meanwhile, the bridge (321) can connect the lever (320) and the support member (330). One end of the bridge (321) is connected to the second rotation axis (323) of the lever (320) at a position spaced apart from the first rotation axis (322), and the other end of the bridge (321) can be connected to one axis (324) of the support member (330).

[0201] As the lever (320) rotates around the first rotation axis (322), when the lever (320) approaches the main body (310), a pushing force is applied to the support member (330) through the bridge (321), and the support member (330) can be moved to the distal end. Conversely, when the lever (320) moves away from the main body (310), the support member (330) can be moved to the proximal end by the bridge (321).

[0202] That is, when the lever (320) moves closer to the main body (310), the support member (330) can advance, and when the lever (320) moves away from the main body (310), the support member (330) can retract.

[0203] To explain this from another perspective, when the lever (320) changes from an initial position to an operating position, the support member (330) can advance, and when the lever (320) returns to an initial position, the support member (330) can retract.

[0204] Meanwhile, the operating part (300) may further include an elastic member (not shown) that applies force to the support member (330) in a distal direction.

[0205] Specifically, although not shown in the drawing, an elastic member may be interposed between the inner surface of the main body (310) to which the receiving portion (210) is attached and the supporting member (330). Additionally, the elastic member may be arranged to surround the extraction member (220).

[0206] Therefore, when the lever (320) is operated to move the support member (330) to the distal side, the elastic member is compressed, and when the external force caused by the operation of the lever (320) is removed, the support member (330) can return to the proximal side by the restoring force of the elastic member.

[0207] As such, the meniscus suturing device according to one embodiment of the present invention includes a lever (320), an elastic member, and a support member (330), making it easy for a user to operate the suturing device with one hand.

[0208] The receiving portion (210) may be formed in a tubular shape that receives at least a portion of the surgical suture. The receiving portion (210) may include a first region (210a) on the distal side (200d) and a second region (210b) on the proximal side (200p) connected to the operating portion (300).

[0209] Specifically, the receiving portion (210) can receive the first fixing member (120) of the suture (100) for the meniscus suturing device.

[0210] Additionally, the side end (211) of the distal portion (200d) of the receiving portion (210) may have a sharp shape like a needle tip. Thus, the receiving portion (210) can penetrate the cartilage plate.

[0211] Additionally, the receiving portion (210) may include a slit (212) formed along the longitudinal direction of the receiving portion (210) at the end of the distal portion (200d).

[0212] The extraction member (220) can move along the longitudinal direction within the receiving portion (210) and can extract a surgical suture.

[0213] Specifically, the extraction member (220) may be formed in a long, slender shape to be received within the receiving portion (210), and one end of the extraction member (220) may be connected to the support member (330) and the other end may be connected to the suture body (110) or the first fixing member (120).

[0214] When the support member (330) moves the extraction member (220) toward the distal portion (200d) by operating the lever (320) described above, the suture body (110) or the first fixing member (120) connected to the other end of the extraction member (220) can move toward the distal portion (200d) within the receiving portion (210).

[0215] A meniscus suturing device according to one embodiment of the present invention can improve surgical convenience by adopting a structure that is easy to operate with one hand, and can improve surgical stability by applying a bioabsorbable surgical suture including a fixing member such as the first fixing member (120).

[0216] Each of the embodiments described above can be implemented independently, but it goes without saying that the structure of each embodiment can be applied in combination to other embodiments.

[0217] As such, the present invention has been described with reference to an embodiment illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and variations of the embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims.

[0218] The present invention relates to a surgical suture and a meniscal suturing device, and can be applied to a suture for a meniscal suturing device that improves the stability of meniscal suturing and to a meniscal suturing device using the same.
