Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an adjustable coil-loop titanium plate device. Background Art

[0002] The titanium plate fixation method with loops is a surgical method for ligament reconstruction. However, in the existing structure of the titanium plate with loops and sutures, the ligaments or ligament grafts at the extension parts on both sides of the coil are not fixed, tightened and fitted well, thereby affecting the healing effect. To address this problem, Chinese patent document CN216257637U discloses an adjustable coil-and-loop titanium plate structure, comprising a titanium plate and a coil. The titanium plate is formed with a traction hole and a loop hole, with a first coil hole and a second coil hole formed between the traction hole and the loop hole. The coil is formed by a titanium plate suture, which includes a left and a right thread sleeve connected to the ends of the central suture, with the other ends of the left and right thread sleeves connected to the left and right sutures, respectively. The left and right thread sleeves have left and right through holes, respectively. The titanium plate suture, through the first and second coil holes, forms a first tensioning section and a second tensioning section to tighten and secure the ligament to the bone. The structure also includes a traction line and a loop line. In this structure, the coil structure and the addition of a tensioning line segment increase the width of the tension fit between the ligament or tendon and the bone, thereby increasing the contact and fusion effect between the ligament or tendon and the bone and improving the healing effect. However, the pulling wire and the loop wire in the above structure are arranged to pass through the pulling hole and the loop hole. When in use, the two ends of the pulling wire or the loop wire need to be controlled, which is inconvenient to use and troublesome to operate. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an adjustable coil-loop titanium plate device, including a titanium plate provided with a pulling hole and a loop hole, a pulling wire cooperating with the pulling hole, a loop wire cooperating with the loop hole, and an adjustable coil cooperating with the first coil hole and the second coil hole between the pulling hole and the loop hole; the pulling wire and / or the loop wire include a fixed section, a perforated section and an operating section, and a first wire sleeve and a second wire sleeve spaced apart are formed on the operating section near the perforated section, the first wire sleeve and the second wire sleeve respectively have a first through hole and a second through hole, and the fixed section cooperates with the first through hole and the second through hole so that the perforated section is passed through the pulling hole and / or the loop hole. By configuring the pull cord and / or flap cord into a fixed section, a perforated section, and an operating section, during use, the fixed section is passed through the pull hole and / or the flap hole, so that the perforated section is located inside and outside the pull hole and / or the flap hole. The free end of the fixed section passes through the first wire sleeve from the first through hole, and then passes through the second wire sleeve from the second through hole. The operating section is then tightened. At this point, the free end of the fixed section is located outside or hidden inside the operating section, while the perforated section encloses the section to form a closed structure. Finally, the operator only needs to operate one end of the pull cord and / or the flap cord, which simplifies operation. Furthermore, the length of the pull cord and / or the flap cord can be greatly shortened compared to the prior art, reducing costs.

[0004] In one embodiment, the fixing section, the perforating section and the operating section are woven together.

[0005] In one embodiment, the fixing section, the perforating section, and the portion of the operating section that removes the first cuff and the second cuff are a single suture.

[0006] In one embodiment, the fixing section, the perforating section, and the portion of the operating section except the first thread sleeve and the second thread sleeve are composite threads braided from a single suture.

[0007] In one embodiment, the adjustable coil is formed by a titanium plate suture, which includes a center sleeve and left and right sutures connected to the center sleeve. The center sleeve has a sleeve through hole, and the titanium plate suture cooperates with the first coil hole and the second coil hole to form a first tightening section and a second tightening section for tightening the ligament or tendon. Compared with existing titanium plate sutures, the structure is simplified and the use is more convenient. That is, the free ends of the left suture and the right suture respectively enter from the two ends of the sleeve through hole and pass through the two ends of the sleeve through hole or pass through the side wall of the sleeve through hole at a suitable position, and then tie a knot.

[0008] In one embodiment, the left suture, the right suture and the midline sleeve are woven together.

[0009] In one embodiment, the left suture and the right suture are a single suture.

[0010] In one embodiment, the left suture and the right suture are composite threads braided from single sutures.

[0011] In one embodiment, the pulling hole, the loop hole, the first coil hole, and the second coil hole are arranged linearly.

[0012] In one embodiment, a recessed structure is formed on the end surface of the titanium plate, located between the first and second coil holes and adjacent to the ligament or tendon. This recessed structure allows the knotting of the left and right sutures to be located there, reducing irritation to the ligament or tendon at the joint. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example 1

[0026] like Figure 1-6As shown, this embodiment discloses an adjustable coil-loop titanium plate device, which includes a titanium plate 3 provided with a pulling hole 1 and a loop hole 2, a pulling wire cooperating with the pulling hole 1, a loop wire 5 cooperating with the loop hole 2, and an adjustable coil cooperating with the first coil hole 6 and the second coil hole 7 between the pulling hole 1 and the loop hole 2; the structure of the titanium plate 3 is not specifically limited. In this embodiment, the titanium plate 3 is a straight bar structure, and its two ends and edges are arc-shaped or chamfered. The pulling hole 1, the loop hole 2, the first coil hole 6 and the second coil hole 7 are arranged linearly. At the same time, the two ends of the above holes are arc-shaped or chamfered. The pulling wire 1 and / or the flap wire 2 includes a fixed section 8, a perforated section 9 and an operating section 10. The perforated section 9 is located between the fixed section 8 and the operating section 10. The length of the fixed section 8 is smaller than the length of the operating section 10. As for the perforated section 9, as long as it can be ensured to be located in the pulling hole 1 or the flap hole 2 and extend a portion thereof, no specific limitation is made. As long as the fixed section 8 is fixed on the operating section 10, a fixed ring is formed; a certain interval is formed on the operating section 10 near the perforated section 9 The first wire sleeve 11 and the second wire sleeve 12 are preferably staggered, and the first wire sleeve 11 and the second wire sleeve 12 respectively form a first through hole and a second through hole, and the fixed segment 8 cooperates with the first through hole and the second through hole. Specifically, after the fixed segment 8 passes through the pulling hole 1 and / or the flap hole 2, the fixed segment 8 first passes through the first wire sleeve 11 through the first through hole, and then passes through the second wire sleeve 12 through the second through hole, and then the operating segment is tightened so that the fixed segment 8 is fixed on the operating segment 10.

[0027] Furthermore, the fixing section 8, the perforating section 9 and the operating section 10 are woven together. As for the composition of the fixing section 8, the perforating section 9 and the operating section 10 (excluding the first thread sleeve 11 and the second thread sleeve 12), it can be a single suture or a composite thread woven from a single suture. Of course, the composite thread can be a linear body or a cylindrical body with a through hole. When a cylindrical body is selected, the inner diameter of the cylindrical body is smaller than the diameter of the first through hole and the second through hole. Of course, the two can also be the same. When they are the same, the fixing section 8, the perforating section 9 and the operating section 10 can also be a cylindrical body with a through hole. At this time, the port position of the first thread sleeve and the second thread sleeve can be fixed by using a needle-like structure or the like to open the corresponding port according to the measured position before use.

[0028] The adjustable coil is formed by titanium plate sutures, which include a center sleeve 13 and a left suture 14 and a right suture 15 connected to the center sleeve 13. The center sleeve 13 has a sleeve through hole. The titanium plate suture cooperates with the first coil hole 6 and the second coil hole 7 to form a first tightening section 16 and a second tightening section 17 for tightening the tendon 19 or the ligament. Specifically, the left suture 14 and the right suture cross and enter the sleeve through hole, and then pass through the sleeve through hole or the side wall of the sleeve through hole. The part of the left suture 14 and the part of the right suture 15 between the two ends of the sleeve through hole form the first tightening section 16 and the second tightening section 17. The first tightening section 16 and the second tightening section 17 refer to the part of the left suture 14 and the part of the right suture 15 outside the sleeve through hole.

[0029] Furthermore, the left suture 14, the right suture 15 and the center line sleeve 13 are woven together. As for the left suture 14 and the right suture 15, they can be single sutures or composite lines woven from single sutures. Of course, the composite line can also be a linear body or a cylindrical body with a through hole. When a cylindrical body is selected, the inner diameter of the cylindrical body is preferably smaller than the diameter of the thread sleeve through hole. Of course, the two can also be the same. When they are the same, the left suture 14, the right suture 15 and the center line sleeve 13 can also be a cylindrical body with a through hole. At this time, the port position of the thread sleeve through hole can be fixed by using a needle-like structure or the like to open the corresponding port according to the measured position before use.

[0030] Furthermore, between the first coil hole 6 and the second coil hole 7, a recessed structure 18 is formed on the end surface of the titanium plate close to the ligament or tendon 19. The recessed structure 18 is not specifically limited and can be set in combination with an arc design or an arc chamfer design. The purpose is to locate the knotting structure of the left suture 14 and the right suture 15 there, thereby reducing or avoiding the irritation of the ligament or tendon 19 by the thread end knot.

[0031] Since the cylindrical body is a linear body, the inner diameter or diameter is determined by the corresponding hole body being expanded to form a standard cylinder.

[0032] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
