在临床医学中，肩锁关节脱位是肩关节损伤的常见疾病之一，手术修复时多采用弹性固定，常使用缝合线和其它植入物(如钛板等)将锁骨固定在喙突上，以达到修复效果。但在手术中需要将缝合线通过骨髓道从锁骨的上侧送至喙突的下侧，为了使缝合线方便穿过骨隧道，通常在建立骨隧道时，将孔径做大一些，便于借助过线器进行穿线，但喙突实际尺寸很小，孔径做大会影响修复效果。In clinical medicine, acromioclavicular joint dislocation is one of the common diseases of shoulder joint injury. Elastic fixation is often used during surgical repair. Sutures and other implants (such as titanium plates, etc.) are often used to fix the clavicle to the coracoid process to achieve the repair effect. However, during the operation, the suture needs to be sent from the upper side of the clavicle to the lower side of the coracoid process through the medullary canal. In order to facilitate the suture to pass through the bone tunnel, the hole diameter is usually made larger when the bone tunnel is established to facilitate threading with the help of a threader. However, the actual size of the coracoid process is very small, and a larger hole diameter will affect the repair effect.

发明内容Summary of the invention

本申请提供一种医用缝合线，其能够实现自行穿线，不需要借助过线器，因此用于穿线的骨隧道的孔径可以做小。The present application provides a medical suture, which can achieve self-threading without the aid of a threader, so the aperture of the bone tunnel used for threading can be made small.

本申请提供一种医用缝合线，包括：The present application provides a medical suture, comprising:

下面结合附图对本申请作进一步详细说明。The present application is further described in detail below with reference to the accompanying drawings.

如图1、图2所示，图1是本申请实施例提供的一种医用缝合线的结构示意图，图2是本申请图1中医用缝合线的剖面结构示意图。所示医用缝合线100包括内芯1和柔性线2，柔性线2包裹在内芯1的外部，柔性线2为编织而成的医用纱线，柔性线2的一端为第一端21，第一端21为封闭端，内芯1的一端为远端11，远端11被封闭在第一端21内，也就是说内芯1无法从柔性线2的第一端21穿出去。该第一端21还包括一尾部211，尾部211属于柔性线2的第一端21的末尾，且尾部211内不设置内芯1。尾部211的长度优选在10毫米-20毫米之间。在本实施例中，尾部211经过热硬化处理，其由热硬化处理前的空心结构变为热硬化处理后的实心结构，且尾部211的硬度大于柔性线2上其它部分的硬度。因为尾部211为实心结构，所以内芯1被尾部211封闭住，无法从尾部211穿出去，也就是说内芯1的远端11被封闭在柔性线2的第一端21内。柔性线2上与第一端21相对的另一端为第二端22，第二端22为开口端，内芯1上与远端11相对的另一端为近端12，近端12伸出第二端22，也就是说，因为第二端22为开口端，即柔性线2在第二端22的端口处是敞开的，没有被封闭起来，故内芯1从柔性线2的第二端22的端口处伸出部分长度，便于在进行缝线手术时，能够夹住该内芯1的伸出部分将内芯1从柔性线2中抽离出来，使缝合线恢复柔软，后续再将柔性线2进行打结或以其它方式固定住手术部位。内芯1由硬质材料制成，优选为金属丝，金属丝中优选为镍钛丝，镍钛丝具有一定硬度，同时还具有很好的柔韧性，由镍钛丝制成的内芯1可以带动柔性线2更容易穿过骨髓道等孔洞，且可以被弯折，若在要穿线的孔洞之间由轻微错位的情况下，本申请的医用缝合线100也能被弯折后很容易穿过去。在其它实施例中，内芯1也可以采用其它硬质材料制成，例如塑料，在本申请中不做限定。As shown in Figures 1 and 2, Figure 1 is a schematic diagram of the structure of a medical suture provided in an embodiment of the present application, and Figure 2 is a schematic diagram of the cross-sectional structure of the medical suture in Figure 1 of the present application. The medical suture 100 shown includes an inner core 1 and a flexible wire 2, the flexible wire 2 is wrapped around the outside of the inner core 1, the flexible wire 2 is a woven medical yarn, one end of the flexible wire 2 is a first end 21, the first end 21 is a closed end, one end of the inner core 1 is a distal end 11, the distal end 11 is closed in the first end 21, that is, the inner core 1 cannot pass through the first end 21 of the flexible wire 2. The first end 21 also includes a tail 211, the tail 211 belongs to the end of the first end 21 of the flexible wire 2, and the inner core 1 is not arranged in the tail 211. The length of the tail 211 is preferably between 10 mm and 20 mm. In this embodiment, the tail portion 211 is heat-hardened, and the hollow structure before the heat-hardening treatment is changed into a solid structure after the heat-hardening treatment, and the hardness of the tail portion 211 is greater than the hardness of other parts of the flexible line 2. Because the tail portion 211 is a solid structure, the inner core 1 is enclosed by the tail portion 211 and cannot pass through the tail portion 211, that is, the distal end 11 of the inner core 1 is enclosed in the first end 21 of the flexible line 2. The other end of the flexible wire 2 opposite to the first end 21 is the second end 22, and the second end 22 is an open end. The other end of the inner core 1 opposite to the distal end 11 is the proximal end 12, and the proximal end 12 extends out of the second end 22. That is to say, because the second end 22 is an open end, that is, the flexible wire 2 is open at the port of the second end 22 and is not closed, the inner core 1 extends part of its length from the port of the second end 22 of the flexible wire 2, so that when performing a suture operation, the protruding part of the inner core 1 can be clamped to pull the inner core 1 out of the flexible wire 2, so that the suture line can be restored to softness, and the flexible wire 2 can be subsequently knotted or fixed to the surgical site in other ways. The inner core 1 is made of a hard material, preferably a metal wire, and the metal wire is preferably a nickel-titanium wire. The nickel-titanium wire has a certain hardness and good flexibility. The inner core 1 made of nickel-titanium wire can drive the flexible wire 2 to pass through the holes such as the medullary canal more easily, and can be bent. If there is a slight misalignment between the holes to be threaded, the medical suture 100 of the present application can also be bent and easily passed through. In other embodiments, the inner core 1 can also be made of other hard materials, such as plastic, which is not limited in the present application.

柔性线2的第一端21包括一实心的尾部211，该实心的尾部211可以将具有一定硬度的内芯1封闭在柔性线2的第一端21内，在缝线手术的穿线过程中，对医用缝合线100向下用力，使内芯1顶住实心的尾部211而不会从尾部211穿出去，故能带动柔性线2一起穿过骨隧道等需要穿线的孔洞，穿线完成后，用夹线钳夹住尾部211，再用手或另一个夹线钳夹住内芯1从柔性线1的第二端22伸出的部分，就可以向上将内芯1从柔性线2中抽离出来，使缝合线恢复柔软，后续再将柔性线2进行打结或以其它方式固定住手术部位。此外，该尾部211经过热硬化处理，其硬度大于未经过热硬化处理过的柔性线的硬度，方便穿线完成后医生在关节镜的辅助下用夹线钳更容易探测到并夹住该医用缝合线100的具有一定硬度的尾部211。柔性线2优选采用超大分子量的聚乙烯材料制成，其具有很大强度，此外柔性线2优选采用菱形编织而成，是一种医用纱线，可以使内芯1从中抽离后该柔性线2仍具有很大的强度。The first end 21 of the flexible wire 2 includes a solid tail 211, and the solid tail 211 can enclose the inner core 1 with a certain hardness in the first end 21 of the flexible wire 2. During the threading process of the suture operation, the medical suture 100 is forced downward so that the inner core 1 can support the solid tail 211 and will not pass out from the tail 211, so that the flexible wire 2 can be driven to pass through the holes such as the bone tunnel that need threading. After the threading is completed, the tail 211 is clamped with a wire clamp, and then the part of the inner core 1 extending from the second end 22 of the flexible wire 1 is clamped by hand or another wire clamp, and the inner core 1 can be pulled out of the flexible wire 2 upward to make the suture line soft again, and then the flexible wire 2 is knotted or fixed to the surgical site in other ways. In addition, the tail 211 is heat-hardened, and its hardness is greater than that of the flexible line that has not been heat-hardened, so that after the threading is completed, the doctor can more easily detect and clamp the tail 211 of the medical suture 100 with a certain hardness with a wire clamp under the assistance of an arthroscopy. The flexible line 2 is preferably made of a polyethylene material with a large molecular weight, which has great strength. In addition, the flexible line 2 is preferably made of a diamond braid, which is a medical yarn, so that the flexible line 2 still has great strength after the inner core 1 is pulled out.

需要说明的是，本实施例中将整个尾部211都进行了热硬化处理，使整个尾部211成为实心结构。在其它实施例中，也可以只将部分尾部211进行热硬化处理，使该经热硬化处理的部分尾部成为实心结构，优选将尾部211上靠近内芯1的部分进行热硬化处理，做成实心结构。It should be noted that in this embodiment, the entire tail portion 211 is heat-hardened to make the entire tail portion 211 a solid structure. In other embodiments, only a portion of the tail portion 211 may be heat-hardened to make the portion of the tail portion that has been heat-hardened a solid structure. Preferably, the portion of the tail portion 211 close to the inner core 1 is heat-hardened to make it a solid structure.

在本申请另一个实施例中的医用缝合线(图中未示出)，其与图1所示医用缝合线100的主要区别在于：尾部211没有经过热硬化处理，而是在尾部211上涂覆有胶水，使尾部211成为实心结构，且尾部211的硬度大于柔性线2上其它部分的硬度。在本实施例中，内芯1的远端11也被实心的尾部211封闭住，无法从尾部211穿出去。除上述区别，本实施例中医用缝合线的其它结构与图1所示医用缝合线100的其它结构均相同或相似，故不再赘述。需要说明的是，本实施例中将整个尾部211都涂覆上胶水，使整个尾部211成为实心结构。在其它实施例中，也可以只将部分尾部211涂覆上胶水，使该涂覆有胶水的部分尾部成为实心结构，优选将尾部211上靠近内芯1的部分涂覆上胶水，做成实心结构。The medical suture in another embodiment of the present application (not shown in the figure) is mainly different from the medical suture 100 shown in Figure 1 in that the tail 211 is not subjected to heat hardening treatment, but is coated with glue on the tail 211, so that the tail 211 becomes a solid structure, and the hardness of the tail 211 is greater than the hardness of other parts on the flexible line 2. In this embodiment, the distal end 11 of the inner core 1 is also closed by the solid tail 211 and cannot be passed through the tail 211. In addition to the above differences, the other structures of the medical suture in this embodiment are the same or similar to the other structures of the medical suture 100 shown in Figure 1, so they are not repeated. It should be noted that in this embodiment, the entire tail 211 is coated with glue to make the entire tail 211 a solid structure. In other embodiments, only part of the tail 211 can be coated with glue to make the part of the tail coated with glue a solid structure, and preferably the part of the tail 211 close to the inner core 1 is coated with glue to make a solid structure.

如图3、图4所示，图3是本申请实施例提供的另一种医用缝合线的结构示意图。图4是本申请图3中医用缝合线的剖面结构示意图。所示医用缝合线100包括内芯1和柔性线2，柔性线2包裹在内芯1的外部，柔性线2为编织而成的医用纱线，柔性线2的一端为第一端21，第一端21为封闭端，内芯1的一端为远端11，远端11被封闭在第一端21内，也就是说内芯1无法从柔性线2的第一端21穿出去。该第一端21还包括一尾部211，尾部211属于柔性线2的第一端21的末尾，且尾部211内不设置内芯1。尾部211的长度优选在10毫米-20毫米之间。在尾部211外还包裹一第一头套3，第一头套3压紧尾部211，使内芯1的远端11被封闭在第一端21内，也就是说被第一头套3压紧的尾部211堵住了内芯1的远端11，使内芯1无法从柔性线2的第一端21穿出去。第一头套3优选采用韧性好的金属制成，在其它实施例中，第一头套3也可以采用塑料或橡胶等材料制成。在本实施例中，第一头套3的长度小于尾部211的长度，其包裹住了靠近内芯1的部分尾部211。在其它实施例中，也可以设置第一头套3的长度大于或等于尾部211的长度，使其完全包裹住尾部211。柔性线2上与第一端21相对的另一端为第二端22，第二端22为开口端，内芯1上与远端11相对的另一端为近端12，近端12伸出第二段22，也就是说，因为第二端22为开口端，即柔性线2在第二端22的端口处是敞开的，没有被封闭起来，故内芯1从柔性线2的第二端22的端口处伸出部分长度，便于在进行缝线手术时，能够夹住该内芯1的伸出部分将内芯1从柔性线2中抽离出来，使缝合线恢复柔软，后续再将柔性线2进行打结或以其它方式固定住手术部位。内芯1由硬质材料制成，优选为金属丝，金属丝中优选为镍钛丝，镍钛丝具有一定硬度，同时还具有很好的柔韧性，由镍钛丝制成的内芯1可以带动柔性线2更容易穿过骨髓道等孔洞，且可以被弯折，若在要穿线的孔洞之间由轻微错位的情况下，本申请的医用缝合线100也能被弯折后很容易穿过去。在其它实施例中，内芯1也可以采用其它硬质材料制成，例如塑料，在本申请中不做限定。As shown in Figures 3 and 4, Figure 3 is a schematic diagram of the structure of another medical suture provided in an embodiment of the present application. Figure 4 is a schematic diagram of the cross-sectional structure of the medical suture in Figure 3 of the present application. The medical suture 100 shown includes an inner core 1 and a flexible wire 2, the flexible wire 2 is wrapped around the outside of the inner core 1, the flexible wire 2 is a woven medical yarn, one end of the flexible wire 2 is a first end 21, the first end 21 is a closed end, one end of the inner core 1 is a distal end 11, and the distal end 11 is closed in the first end 21, that is, the inner core 1 cannot pass through the first end 21 of the flexible wire 2. The first end 21 also includes a tail 211, the tail 211 belongs to the end of the first end 21 of the flexible wire 2, and the inner core 1 is not arranged in the tail 211. The length of the tail 211 is preferably between 10 mm and 20 mm. A first head cover 3 is also wrapped outside the tail portion 211. The first head cover 3 presses the tail portion 211 so that the distal end 11 of the inner core 1 is enclosed in the first end 21. In other words, the tail portion 211 pressed by the first head cover 3 blocks the distal end 11 of the inner core 1, so that the inner core 1 cannot pass through the first end 21 of the flexible line 2. The first head cover 3 is preferably made of a metal with good toughness. In other embodiments, the first head cover 3 can also be made of materials such as plastic or rubber. In this embodiment, the length of the first head cover 3 is less than the length of the tail portion 211, and it wraps the part of the tail portion 211 close to the inner core 1. In other embodiments, the length of the first head cover 3 can also be set to be greater than or equal to the length of the tail portion 211 so that it completely wraps the tail 211. The other end of the flexible wire 2 opposite to the first end 21 is the second end 22, and the second end 22 is an open end. The other end of the inner core 1 opposite to the distal end 11 is the proximal end 12, and the proximal end 12 extends out of the second section 22. That is to say, because the second end 22 is an open end, that is, the flexible wire 2 is open at the port of the second end 22 and is not closed, the inner core 1 extends part of its length from the port of the second end 22 of the flexible wire 2, so that when performing a suture operation, the protruding part of the inner core 1 can be clamped to pull the inner core 1 out of the flexible wire 2, so that the suture line becomes soft again, and the flexible wire 2 is subsequently knotted or fixed to the surgical site in other ways. The inner core 1 is made of a hard material, preferably a metal wire, and the metal wire is preferably a nickel-titanium wire. The nickel-titanium wire has a certain hardness and good flexibility. The inner core 1 made of nickel-titanium wire can drive the flexible wire 2 to pass through the holes such as the medullary canal more easily, and can be bent. If there is a slight misalignment between the holes to be threaded, the medical suture 100 of the present application can also be bent and easily passed through. In other embodiments, the inner core 1 can also be made of other hard materials, such as plastic, which is not limited in the present application.

此外，该尾部211外包裹一第一头套3，因第一头套3的硬度较大，方便穿线完成后医生在关节镜的辅助下用夹线钳更容易探测到并夹住该医用缝合线100的具有一定硬度的尾部211。柔性线2优选采用超大分子量的聚乙烯材料制成，其具有很大强度，此外柔性线2优选采用菱形编织而成，是一种医用纱线，可以使内芯1从中抽离后该柔性线2仍具有很大的强度。In addition, the tail 211 is wrapped with a first head cover 3. Since the first head cover 3 has a relatively high hardness, it is convenient for the doctor to detect and clamp the tail 211 of the medical suture 100 with a certain hardness with a wire clamp under the assistance of an arthroscopy after the threading is completed. The flexible wire 2 is preferably made of a polyethylene material with a large molecular weight, which has great strength. In addition, the flexible wire 2 is preferably woven in a diamond shape, which is a medical yarn, so that the flexible wire 2 still has great strength after the inner core 1 is pulled out.

如图5所示，图5是本申请实施例提供的另一种医用缝合线的剖面结构示意图。该医用缝合线100与图2所示医用缝合线100的主要区别在于：包裹在内芯1的远端11外的部分柔性线2为第一柔性线23，该第一柔性线23也经过热硬化处理，故其致密度变大，可以进一步防止在穿线过程中内芯1的远端11从该第一柔性线23处穿出来。除上述区别，本实施例中医用缝合线100的其它结构与图2所示医用缝合线100的其它结构均相同或相似，故不再赘述。As shown in FIG5 , FIG5 is a schematic diagram of the cross-sectional structure of another medical suture provided in an embodiment of the present application. The main difference between the medical suture 100 and the medical suture 100 shown in FIG2 is that the part of the flexible wire 2 wrapped outside the distal end 11 of the inner core 1 is the first flexible wire 23, and the first flexible wire 23 is also subjected to heat hardening treatment, so its density becomes larger, which can further prevent the distal end 11 of the inner core 1 from passing out from the first flexible wire 23 during the threading process. Except for the above differences, the other structures of the medical suture 100 in this embodiment are the same or similar to the other structures of the medical suture 100 shown in FIG2, so they are not repeated.

如图6所示，图6是本申请实施例提供的另一种医用缝合线的剖面结构示意图。该医用缝合线100与图2所示医用缝合线100的主要区别在于两点：第一点，尾部211没有经过热硬化处理，而是在尾部211上涂覆有胶水，使尾部211成为实心结构，且尾部211的硬度大于柔性线2上没有涂覆胶水部分的硬度。在本实施例中，内芯1的远端11也被实心的尾部211封闭住，无法从尾部211穿出去；第二点，包裹在内芯1的远端11外的部分柔性线2为第二柔性线24，该第二柔性线24上也涂覆有胶水，故其致密度变大，可以进一步防止在穿线过程中内芯1的远端11从该第二柔性线24处穿出来。除上述两点区别，本实施例中医用缝合线100的其它结构与图2所示医用缝合线100的其它结构均相同或相似，故不再赘述。As shown in FIG6 , FIG6 is a schematic diagram of the cross-sectional structure of another medical suture provided in an embodiment of the present application. The main differences between the medical suture 100 and the medical suture 100 shown in FIG2 are two points: first, the tail 211 is not subjected to heat hardening treatment, but is coated with glue on the tail 211, so that the tail 211 becomes a solid structure, and the hardness of the tail 211 is greater than the hardness of the part of the flexible line 2 that is not coated with glue. In this embodiment, the distal end 11 of the inner core 1 is also closed by the solid tail 211 and cannot pass through the tail 211; second, the part of the flexible line 2 wrapped outside the distal end 11 of the inner core 1 is the second flexible line 24, and the second flexible line 24 is also coated with glue, so its density becomes larger, which can further prevent the distal end 11 of the inner core 1 from passing through the second flexible line 24 during the threading process. Except for the above two differences, other structures of the medical suture 100 in this embodiment are the same or similar to other structures of the medical suture 100 shown in FIG. 2 , and thus will not be described in detail.

如图7、图8所示，图7是本申请实施例提供的另一种医用缝合线的结构示意图，图8是本申请图7中医用缝合线的剖面结构示意图。该医用缝合线100与图3、图4所示医用缝合线100的主要区别在于：包裹在内芯1的远端11外的部分柔性线2为第三柔性线25，该第三柔性线25外还包裹一辅助套4，该辅助套4优选采用韧性好的金属制成，其可以进一步防止在穿线过程中内芯1的远端11从该第三柔性线25处穿出来。除上述区别，本实施例中医用缝合线100的其它结构与图3、图4所示医用缝合线100的其它结构均相同或相似，故不再赘述。As shown in Figures 7 and 8, Figure 7 is a schematic diagram of the structure of another medical suture provided in an embodiment of the present application, and Figure 8 is a schematic diagram of the cross-sectional structure of the medical suture in Figure 7 of the present application. The main difference between the medical suture 100 and the medical suture 100 shown in Figures 3 and 4 is that the part of the flexible wire 2 wrapped outside the distal end 11 of the inner core 1 is a third flexible wire 25, and the third flexible wire 25 is also wrapped with an auxiliary sleeve 4, which is preferably made of a metal with good toughness, which can further prevent the distal end 11 of the inner core 1 from passing out from the third flexible wire 25 during the threading process. In addition to the above differences, the other structures of the medical suture 100 in this embodiment are the same or similar to the other structures of the medical suture 100 shown in Figures 3 and 4, so they are not repeated here.

如图9、图10所示，图9是本申请实施例提供的另一种医用缝合线的结构示意图，图10是本申请图9中医用缝合线的剖面结构示意图。所示医用缝合线100包括内芯1和柔性线2，柔性线2包裹在内芯1的外部，柔性线2的一端为第一端21，第一端21为封闭端，内芯1的一端为远端11，远端11被封闭在第一端21内，也就是说内芯1无法从柔性线2的第一端21穿出去。在柔性线2的第一端21外包裹一第二头套5，第二头套5压紧至少部分第一端21，使内芯1的远端11被封闭在第一端21内，也就是说被第二头套5压紧的第一端21堵住了内芯1的远端11，使内芯1无法从柔性线2的第一端21穿出去。第二头套5优选采用韧性好的金属制成，在其它实施例中，第二头套5也可以采用塑料或橡胶等材料制成。在本实施例中，在柔性线2的长度方向上，第二头套5的长度大于第一端21的长度，也就是说第二头套5超出第一端21部分长度，并且将超出部分的末端的前后部分压紧贴合在一起形成一第一封口51，使内芯1无法从柔性线2的第一端21穿出去。在本实施例中，第二头套5在轴向上的两端均是敞口，没有被堵住。柔性线2上与第一端21相对的另一端为第二端22，第二端22为开口端，内芯1上与远端11相对的另一端为近端12，近端12伸出第二段22，也就是说，因为第二端22为开口端，即柔性线2在第二端22的端口处是敞开的，没有被封闭起来，故内芯1从柔性线2的第二端22的端口处伸出部分长度，便于在进行缝线手术时，能够夹住该内芯1的伸出部分将内芯1从柔性线2中抽离出来，使缝合线恢复柔软，后续再将柔性线2进行打结或以其它方式固定住手术部位。内芯1由硬质材料制成，优选为金属丝，金属丝中优选为镍钛丝，镍钛丝具有一定硬度，同时还具有很好的柔韧性，由镍钛丝制成的内芯1可以带动柔性线2更容易穿过骨髓道等孔洞，且可以被弯折，若在要穿线的孔洞之间由轻微错位的情况下，本申请的医用缝合线100也能被弯折后很容易穿过去。在其它实施例中，内芯1也可以采用其它硬质材料制成，例如塑料，在本申请中不做限定。As shown in Figures 9 and 10, Figure 9 is a schematic diagram of the structure of another medical suture provided in an embodiment of the present application, and Figure 10 is a schematic diagram of the cross-sectional structure of the medical suture in Figure 9 of the present application. The medical suture 100 shown includes an inner core 1 and a flexible wire 2, the flexible wire 2 is wrapped around the outside of the inner core 1, one end of the flexible wire 2 is a first end 21, the first end 21 is a closed end, one end of the inner core 1 is a distal end 11, and the distal end 11 is closed in the first end 21, that is, the inner core 1 cannot pass through the first end 21 of the flexible wire 2. A second head cover 5 is wrapped around the first end 21 of the flexible wire 2, and the second head cover 5 presses at least part of the first end 21, so that the distal end 11 of the inner core 1 is closed in the first end 21, that is, the first end 21 pressed by the second head cover 5 blocks the distal end 11 of the inner core 1, so that the inner core 1 cannot pass through the first end 21 of the flexible wire 2. The second head cover 5 is preferably made of a metal with good toughness. In other embodiments, the second head cover 5 can also be made of materials such as plastic or rubber. In this embodiment, in the length direction of the flexible wire 2, the length of the second head cover 5 is greater than the length of the first end 21, that is, the second head cover 5 exceeds the length of the first end 21, and the front and rear parts of the end of the exceeding part are pressed together to form a first seal 51, so that the inner core 1 cannot pass through the first end 21 of the flexible wire 2. In this embodiment, both ends of the second head cover 5 in the axial direction are open and not blocked. The other end of the flexible wire 2 opposite to the first end 21 is the second end 22, and the second end 22 is an open end. The other end of the inner core 1 opposite to the distal end 11 is the proximal end 12, and the proximal end 12 extends out of the second section 22. That is to say, because the second end 22 is an open end, that is, the flexible wire 2 is open at the port of the second end 22 and is not closed, the inner core 1 extends part of its length from the port of the second end 22 of the flexible wire 2, so that when performing a suture operation, the protruding part of the inner core 1 can be clamped to pull the inner core 1 out of the flexible wire 2, so that the suture line becomes soft again, and the flexible wire 2 is subsequently knotted or fixed to the surgical site in other ways. The inner core 1 is made of a hard material, preferably a metal wire, and the metal wire is preferably a nickel-titanium wire. The nickel-titanium wire has a certain hardness and good flexibility. The inner core 1 made of nickel-titanium wire can drive the flexible wire 2 to pass through the holes such as the medullary canal more easily, and can be bent. If there is a slight misalignment between the holes to be threaded, the medical suture 100 of the present application can also be bent and easily passed through. In other embodiments, the inner core 1 can also be made of other hard materials, such as plastic, which is not limited in the present application.

柔性线2优选采用超大分子量的聚乙烯材料制成，其具有很大强度，此外柔性线2优选采用菱形编织而成，是一种医用纱线，可以使内芯1从中抽离后该柔性线2仍具有很大的强度。The flexible wire 2 is preferably made of ultra-high molecular weight polyethylene material, which has great strength. In addition, the flexible wire 2 is preferably woven in a diamond shape, which is a medical yarn, so that the flexible wire 2 still has great strength after the inner core 1 is pulled out.

如图11、图12所示，图11是本申请实施例提供的另一种医用缝合线的结构示意图，图12是本申请图11中医用缝合线的剖面结构示意图。该医用缝合线100与图9、图10所示医用缝合线100的主要区别在于第二头套5的结构不同。本实施例中第二头套5在轴向上的一端是敞口，没有被堵住，另一端则是被与第二头套5一体成型的堵头52堵住的，形成一第二封口53，该第二封口53堵住内芯1的远端11，使内芯1无法从柔性线2的第一端21穿出去。除上述区别，本实施例中第二头套5的其它结构与图9、图10所示医用缝合线100上第二头套5的其它结构均相同或相似，故不再赘述。As shown in Figures 11 and 12, Figure 11 is a schematic diagram of the structure of another medical suture provided in an embodiment of the present application, and Figure 12 is a schematic diagram of the cross-sectional structure of the medical suture in Figure 11 of the present application. The main difference between the medical suture 100 and the medical suture 100 shown in Figures 9 and 10 is that the structure of the second head cover 5 is different. In this embodiment, one end of the second head cover 5 in the axial direction is open and not blocked, and the other end is blocked by a plug 52 integrally formed with the second head cover 5, forming a second seal 53, which blocks the distal end 11 of the inner core 1, so that the inner core 1 cannot pass through the first end 21 of the flexible line 2. Except for the above differences, the other structures of the second head cover 5 in this embodiment are the same or similar to the other structures of the second head cover 5 on the medical suture 100 shown in Figures 9 and 10, so they are not repeated.

如图13、图14所示，图13是本申请实施例提供的在肩关节上进行穿线的结构示意图。图14是本申请实施例提供的一种医用缝合线的穿线方法。本实施例以在肩关节上进行穿线为例来说明本申请实施例中任一种医用缝合线100的穿线方法，包括：As shown in Figures 13 and 14, Figure 13 is a schematic diagram of the structure of threading on a shoulder joint provided in an embodiment of the present application. Figure 14 is a threading method of a medical suture provided in an embodiment of the present application. This embodiment takes threading on a shoulder joint as an example to illustrate any threading method of a medical suture 100 in an embodiment of the present application, including:

第一步S1：用手或手术钳夹住医用缝合线100，以第一端21为起始端，将医用缝合线100穿入锁骨上已打好的第一骨髓道201内；Step S1: Clamp the medical suture 100 by hand or surgical forceps, and insert the medical suture 100 into the first medullary canal 201 on the clavicle with the first end 21 as the starting end;

第二步S2：对医用缝合线100向下用力，使内芯1带动柔性线2一起穿过第一骨隧道201后再穿入喙突300上已打好的第二骨髓道301内；Step 2 S2: Apply downward force to the medical suture 100 so that the inner core 1 drives the flexible wire 2 to pass through the first bone tunnel 201 and then into the second bone marrow canal 301 that has been drilled on the coracoid process 300;

第三步S3：医用缝合线100从第二骨髓道301穿出后，用夹线钳夹住尾部211或第二头套5，再用手或手术钳夹住内芯1从柔性线2的第二端22伸出的部分，向上牵拉将内芯1从柔性线2中抽离出来。Step 3 S3: After the medical suture thread 100 passes through the second medullary canal 301, clamp the tail 211 or the second head cover 5 with a wire clamp, then clamp the part of the inner core 1 extending from the second end 22 of the flexible wire 2 with hands or surgical forceps, and pull upward to pull the inner core 1 out of the flexible wire 2.

内芯1从柔性线2中抽离出来后，使缝合线恢复柔软，后续再将柔性线2进行打结或以其它方式将锁骨固定在喙突上。本申请实施例的医用缝合线，由于在柔性线内包裹一由硬质材料制成的内芯，故该医用缝合线具有一定的硬度，医生可以直接用手或者借助手术钳将医用缝合线穿过骨隧道，不需要借助过线器，所以用于穿线的骨隧道的孔径即使做小也能实现该医用缝合线的自行穿线。After the inner core 1 is pulled out from the flexible wire 2, the suture is restored to be soft, and the flexible wire 2 is subsequently knotted or otherwise used to fix the clavicle to the coracoid process. The medical suture of the embodiment of the present application has a certain hardness because an inner core made of a hard material is wrapped in the flexible wire. The doctor can directly pass the medical suture through the bone tunnel by hand or with the help of surgical forceps without the help of a threader, so even if the aperture of the bone tunnel used for threading is made small, the medical suture can be threaded by itself.
