Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a looped titanium plate and a preparation method thereof. BACKGROUND

[0002] The looped titanium plate is an important medical device product in the field of orthopedic sports medicine, which is mainly used for fixing the reconstructed ligament in the treatment of ACL rupture or injury, has the characteristics of high strength and firm fixation, and is a great innovation in the field of sports medicine, which is superior to the previous treatment method.

[0003] As shown in Figure 1 and Figure 2 , the looped titanium plate generally comprises a titanium alloy plate with a hole (referred to as titanium plate) 20, an adjustable or non-adjustable wire ring 30, a traction wire 40, and a loop turning wire 50. When applied to the treatment of ACL rupture or injury, tunnels are drilled on the tibia and femur, one end of the artificial tendon or ligament 10 used for ligament reconstruction is passed through the wire ring 30 on the titanium plate 20, and then the artificial tendon or ligament 10 is pulled through the tibial and femoral tunnels through the traction wire 40 on the titanium plate 20 until the titanium plate 20 reaches the surface of the cortical bone that can be turned over, at which time the titanium plate is suspended on the lateral side of the femur through the loop turning wire 50. The other end of the artificial tendon or ligament is passed through the tibial tunnel and the tendon ligament fixation device (such as tendon ligament fixation screw, U-shaped nail, etc., which can also be a looped fixation plate) is fixed on the tibial end. By fixing the femoral end and the tibial end, and gradually growing tissue to cover and wrap the looped titanium plate, it can provide sufficient mechanical fixation to restore the stability of the joint.

[0004] At present, since the traction wire and the loop turning wire are usually the same type of suture with consistent diameter and consistent structure, such suture usually has a compact structure and a smooth surface, so during the operation process, a certain force is required to pull the knee joint reconstruction system (including the looped titanium plate suspension fixation system and the artificial ligament or tendon), which is prone to traction disadvantage, resulting in slipping phenomenon; at the same time, the traction wire and the loop turning wire generally need to be distinguished by different color patterns, but since they have consistent diameter and consistent structure, they are not easy to distinguish in actual use, which is not conducive to actual use. SUMMARY

[0005] The purpose of the present application is to provide a looped titanium plate which can avoid the slipping phenomenon caused by traction disadvantage and can easily distinguish the traction wire and the loop turning wire.

[0006] To solve the above technical problems, the application provides a band loop titanium plate, which comprises a titanium plate body, a wire ring, a traction wire and a loop turning wire.

[0007] Optionally, the loop turning wire is made of first yarn, and the traction wire is made of second yarn, wherein the diameter of the second yarn is larger than that of the first yarn.

[0008] Further, the diameter of the first yarn is 20 denier to 400 denier, and the diameter of the second yarn is 30 denier to 500 denier.

[0009] Further, the weaving structure of the loop turning wire is 2-press-1 or 1-press-1, and the weaving structure of the traction wire is 2-press-1 or 1-press-1.

[0010] Further, the weaving weft density of the loop turning wire is 30 nodes / inch to 100 nodes / inch, the weaving weft density of the traction wire is 20 nodes / inch to 90 nodes / inch, and the weaving weft density of the loop turning wire is larger than that of the traction wire.

[0011] Optionally, the titanium plate body comprises two first through holes and at least two second through holes, the two first through holes are used for mounting the loop turning wire and the traction wire respectively, and the at least two second through holes are used for mounting the wire ring.

[0012] Further, the wire ring comprises:

[0013] an adjustable wire ring formed by at least two hollow weaving wires after being woven and connected to each other after passing through the at least two second through holes, and the adjustable wire ring has two free ends; and

[0014] a non-adjustable wire ring formed by yarns passing through the two second through holes in sequence and being artificially or mechanically spirally wound along the circumference of the yarns.

[0015] On the other hand, the application also provides a preparation method of the band loop titanium plate, which comprises the following steps:

[0016] forming the loop turning wire by the ordered rotation of the clockwise rotating weaving walk-on spindles and the counterclockwise rotating weaving walk-on spindles on the weaving machine;

[0017] forming the traction wire by the ordered rotation of the clockwise rotating weaving walk-on spindles and the counterclockwise rotating weaving walk-on spindles on the weaving machine, so as to form the band loop titanium plate, wherein the structure of the traction wire and the loop turning wire is different.

[0018] Optionally, the number of knitting needles required for knitting the flip loop line is greater than or equal to the number of knitting needles required for knitting the traction line.

[0019] Optionally, the flip loop line is knitted with a first yarn, and the traction line is knitted with a second yarn, and the diameter of the second yarn is greater than the diameter of the first yarn.

[0020] Compared with the prior art, the present application has the following advantages:

[0021] The present application provides a titanium plate with a loop, comprising a titanium plate body, a wire ring, a traction line, and a flip loop line, characterized in that the traction line, the wire ring, and the flip loop line are sequentially and spacedly installed along the length direction of the titanium plate body on the titanium plate body, and the structure of the traction line and the flip loop line is different. The structure difference between the traction line and the flip loop line facilitates the distinction between them in actual use, and the distinction can be made without using multi-color patterns, so that the purchase of multi-color raw materials is not required, and the purchase and testing costs are saved.

[0022] Further, the flip loop line is knitted with a first yarn, and the traction line is knitted with a second yarn, and the diameter of the second yarn is greater than the diameter of the first yarn, so that the surface friction is greater, and when the diameters of the traction line and the flip loop line remain the same during use, the two can be easily distinguished, and the slipping phenomenon during traction is eliminated, so that the performance of the titanium plate with a loop is improved.

[0040] As shown in Figures 3-9 The present application provides a titanium plate with a loop, which comprises a titanium plate body 100, a wire ring 200, a traction wire 300 and a flip loop wire 400, wherein the wire ring 200, the traction wire 300 and the flip loop wire 400 are sequentially and spacedly installed on the titanium plate body 100. Specifically, the traction wire 300 and the flip loop wire 400 are installed on the two sides of the titanium plate body 100 along the length direction thereof, and the wire ring 200 is installed on the titanium plate body 100 between the traction wire 300 and the flip loop wire 400.

[0041] The titanium plate body 100 can be made of titanium or titanium alloy, preferably, the titanium plate body 100 can be made of medical titanium or medical titanium alloy. The titanium plate body 100 is, for example, a long strip, specifically, the edges and corners of the titanium plate body 100 are arc-shaped, which is beautiful and does not hurt the suture (i.e. the wire ring 200, the traction wire 300 and the flip loop wire 400).

[0042] The titanium plate body 100 is formed with two first through holes 111, 112 and a plurality of second through holes 120. The two first through holes 111, 112 and the plurality of second through holes 120 are uniformly arranged on the titanium plate body 100, and the two first through holes 111, 112 are arranged on both sides of the titanium plate body 100 along the length direction of the titanium plate body 100, and the plurality of second through holes 120 are arranged between the two first through holes 111, 112, and the two first through holes 111, 112 are symmetrically arranged. The first through holes 111, 112 and the second through holes 120 all penetrate the titanium plate body 100 along the thickness direction of the titanium plate body 100, and the axes of the first through holes 111, 112 and the second through holes 120 are parallel to each other. The aperture of the second through hole 120 can be set as required. The first through holes 111, 112 and the second through holes 120 are, for example, circular holes or special-shaped holes, and preferably, the first through holes and the second through holes are both circular holes. The edges of the first through holes 111, 112 and the second through holes 120 are all chamfered to avoid damage to the traction line 300, the flip coil line 400 and the wire ring 200.

[0043] The plurality of second through holes 120 are used to mount the wire ring, and the two first through holes 111, 112 are respectively used to mount the traction line 300 and the flip coil line 400. The number of the second through holes 120 is at least two, and preferably, the number of the second through holes 120 is, for example, 2-6, and the second through holes 120 can be arranged side by side in pairs, or can be arranged in sequence along the length direction of the titanium plate body 100, and preferably, the center positions of the first through holes 111, 112 and the second through holes 120 are located on the same straight line, or part of the second through holes 120 can be arranged side by side in pairs first, and then arranged with the remaining second through holes 120 along the length direction of the titanium plate body 100. As shown in the figure, the titanium plate body 100 is formed with two first through holes 111, 112 and two second through holes 121, 122. The two first through holes 111, 112 are arranged on both sides of the length direction of the titanium plate body 100, the two second through holes 121, 122 are arranged in sequence along the length direction of the titanium plate body 100, and the centers of the two first through holes 111, 112 and the two second through holes 121, 122 are on the same straight line. Figure 3 Figure 4 ​As shown in the figure, the titanium plate body 100 is formed with two first through holes 111, 112 and six second through holes 121, 122, 123, 124, 125, 126. The two first through holes 111, 112 are arranged on both sides of the length direction of the titanium plate body 100. The four second through holes 122, 123, 124, 125 are arranged side by side in pairs, and the second through holes 121, 126 are sequentially arranged along the length direction of the titanium plate body 100. The six second through holes 121, 122, 123, 124, 125, 126 are located between the two first through holes 111, 112 along the length direction of the titanium plate body 100.

[0044] As shown in the figure, Figure 5 The wire ring 200 can be an adjustable wire ring 220, and the adjustable wire ring 220 can be formed by at least two hollow braided wires connected to each other by braiding. As shown in the figure,

[0045] As shown in the figure, Figure 6 And 7 The wire ring 200 can also be an adjustable wire ring 220, and the adjustable wire ring 220 can be formed by at least two hollow braided wires connected to each other by braiding. As shown in the figure, Figure 6 The adjustable wire ring 220 is formed by two hollow braided wires 221, 222 connected to each other by braiding. Both of the two hollow braided wires 221, 222 have two free ends, and the two hollow braided wires 221, 222 are connected to each other by crossing. One free end of the hollow braided wire 221 passes through the second through hole 121 from the same side of the titanium plate body 100, and one free end of the hollow braided wire 222 passes through the second through hole 122 from the same side of the titanium plate body 100, and is connected on the other side of the titanium plate body 100, so that the adjustable wire ring 220 is connected in a ring shape. The other free end of the hollow braided wire 221, 222 passes through the second through hole 121, 122 from the same side of the titanium plate body 100, and the length of the ring structure of the adjustable wire ring 220 can be adjusted by pulling the other free end of the two hollow braided wires 221, 222. As shown in the figure, Figure 7As shown, the adjustable wire ring 220 is formed by three hollow braided wires 221, 222, 223 connected with each other, the three hollow braided wires 221, 222, 223 are connected by braiding, and the three hollow braided wires 221, 222, 223 after braiding connection all have two free ends, wherein the two free ends of two hollow braided wires 221, 222 pass through four second through holes arranged side by side two by two on the same side, and one free end of two by two is connected on the other side, and the other free end of two by two is connected, and the two free ends of the hollow braided wire 223 pass through two second through holes on both sides of the four second through holes arranged side by side two by two, and the length of the loop structure of the adjustable wire ring 220 can be adjusted by pulling the two free ends of the hollow braided wire 223. Wherein, in order to prevent the wire ring 200 from being cut, the second through holes passing through the free ends of the two connected hollow braided wires 221, 222 have a communication groove.

[0046] As shown in Figure 8 and 9 The model of the suture line 400 and the traction line 300 is 2-6, and the diameter of the suture line 400 and the diameter of the traction line 300 are, for example, 0.700mm-0.799mm, and the model of the suture line of the traction line 300 and the suture line 400 is the same. The structure of the traction line 300 and the suture line 400 is different. The suture line 400 is made of a first yarn on a braiding machine, and the diameter of the first yarn is 180 denier; the traction line 300 is made of a second yarn on a braiding machine, and the diameter of the second yarn is 280 denier, and the diameter of the second yarn is larger than the diameter of the first yarn, that is, the second yarn is thicker than the first yarn.

[0047] It can be seen that, since the traction line 300 adopts different braiding structures, it is easy to distinguish it from the suture line in actual use, and it can also be distinguished without using multi-color patterns, so that multi-color raw materials do not need to be purchased, and procurement and testing expenses are saved.

[0048] The embodiment also provides a preparation method of the titanium plate with a loop, comprising the following steps:

[0049] The suture line is braided on a braiding machine through the orderly rotation of the clockwise rotating braiding walkman and the counterclockwise rotating braiding walkman;

[0050] The traction line is braided on a braiding machine through the orderly rotation of the clockwise rotating braiding walkman and the counterclockwise rotating braiding walkman, thereby forming the titanium plate with a loop, wherein the structure of the traction line and the suture line is different.

[0051] The number of braiding spindles required to form the loop line is greater than or equal to the number of braiding spindles required to form the traction line. Those skilled in the art should understand that the loop line and the traction line can be formed separately on the same braiding machine or on different braiding machines.

[0052] Specifically, in one embodiment, a first braiding machine is used to braid a loop line, and a second braiding machine is used to braid a guide line. The first braiding machine has a larger number of braiding spindles than the second braiding machine. All the braiding spindles of the first braiding machine are selected and braided using a higher weft density to obtain the loop line 400. All the braiding spindles of the second braiding machine are selected and braided using a lower weft density to obtain the guide line 300. The weft density of the loop line 400 is 50 knots / inch to 60 knots / inch, and the weft density of the guide line 300 is 30 knots / inch to 40 knots / inch, with the loop line 400 having a higher weft density than the guide line 300. The braiding structure of the looping wire 400 and the traction wire 300 is, for example, 2-over-1. However, the braiding texture of the traction wire 300 is more prominent, that is, the surface roughness of the traction wire 300 is larger, which makes the surface friction of the traction wire 300 larger. The traction wire 300 uses a softer and lower weft density than the looping wire 400, and the resulting braiding structure is looser than that of the looping wire 400. This results in a softer traction wire 300 than the looping wire 400, thereby improving the operability of the traction wire 300.

[0053] In another embodiment, the first and second knitting machines are knitting machines with the same number of knitting spindles. All knitting spindles of the first knitting machine are selected and knitted using a higher weft density to obtain a loop thread of 400. 1 / 2, 1 / 4, 1 / 8, 1 / 16, etc. (i.e., 2) of the second knitting machine's spindles are selected. -n Weaving is performed using a number of weaving spindles, specifically, half of the selected weaving spindles (i.e., 2) -n-1 The quantity of weaving spindles is 1 / 2, which are weaving spindles that move in a clockwise direction. The other half (i.e., 2) -n-1 The selected weaving spindles are evenly arranged and woven with a lower weft density to obtain the traction line 300. The weft density of the traction line 300 is lower than that of the loop line 400. The weaving structure of the loop line 400 is, for example, 2-over-1, while the weaving structure of the traction line 300 is, for example, 1-over-1. The weaving texture of the traction line 300 is more prominent, that is, the surface roughness of the traction line 300 is greater, resulting in greater surface friction and making it softer than the loop line 400.

[0054] In still another embodiment, the first braider and the second braider are braiders with the same number of braiding doupers, and the first braider is selected to have 1 / 2, 1 / 4, 1 / 8, 1 / 16, etc. (i.e., 2 -n ) number of braiding doupers and to use a higher braiding weft density for braiding, specifically, half of the selected braiding doupers are clockwise running braiding doupers, and the other half of the selected braiding doupers are counterclockwise running braiding doupers, the selected braiding doupers are uniformly arranged and braided using a higher braiding weft density to obtain the flipper line 400; the second braider is selected to have a smaller number of braiding doupers than the number of braiding doupers used by the first braider and to use a lower braiding weft density for braiding, specifically, half of the selected braiding doupers are clockwise running braiding doupers, and the other half of the selected braiding doupers are counterclockwise running braiding doupers, the selected braiding doupers are uniformly arranged and braided using a lower braiding weft density to obtain the traction line 300. The braiding weft density used by the traction line 300 is lower than the braiding weft density used by the flipper line 400, and the braiding structures of the flipper line 400 and the traction line 300 are both, for example, 1-press-1, but the braiding texture of the traction line 300 is more prominent, i.e., the surface roughness of the traction line 300 is larger, so that the surface friction of the traction line 300 is larger, and the traction line 300 is softer than the flipper line 400.

[0055] It can be seen that the traction line 300 and the flipper line 400 have different structures and effects due to the difference in the thickness of the first yarn and the second yarn, the number of braiding doupers and their arrangement, and the cooperation of the braiding weft density, and it can also be seen that the thicker the first yarn used by the traction line 300, the fewer the number of braiding doupers, the more prominent the braiding texture of the traction line 300, and the larger the surface friction, so that the traction line 300 and the flipper line 400 can be easily distinguished when the diameters of the two lines remain the same during use, and the slipping phenomenon during surgical traction is also eliminated, so that the performance of the traction line 300 and the flipper line 400 with the looped titanium plate is improved. In addition, since the traction line 300 adopts different braiding structures, it is easy to distinguish it from the flipper line during actual use, and it can also be distinguished without using multi-color patterns, so that it is not necessary to purchase multi-color raw materials, and the procurement and testing costs are saved.

[0056] In summary, the application provides a band titanium plate, comprising a titanium plate body, a wire ring, a traction line and a flip line, characterized in that the traction line, the wire ring and the flip line are sequentially and spacedly installed on the titanium plate body along the length direction of the titanium plate body, and the structures of the traction line and the flip line are different.

[0057] Further, the flip line is made of a first yarn, and the traction line is made of a second yarn, the diameter of the second yarn is larger than that of the first yarn, so that the surface friction is larger, thereby the traction line and the flip line can be easily distinguished when the diameters are consistent during use, and the slip phenomenon during traction is eliminated, so that the performance of the band titanium plate with the traction line and the flip line is improved.

[0058] In addition, it should be noted that, unless specifically described or indicated, the terms "first", "second" and the like in the specification are only used to distinguish the components, elements, steps and the like in the specification, and are not used to indicate the logical relationship or sequence relationship between the components, elements, steps and the like.

For any skilled person in the art, many possible changes and modifications or equivalent embodiments of the technical solutions of the application can be made by using the disclosed technical content without departing from the scope of the technical solutions of the application.
