Embodiment 1

[0027] An embodiment of the present invention provides a length-adjustable suspension ring fixing plate device, such as figure 1 As shown, it includes a fixed plate 1, a suture segment 2, and a traction line 3 and a loop line 4 arranged at both ends of the fixed plate; wherein, the fixed plate 1 is provided with some The suture line through hole 5; the suture line segment 2 passes through the suture line through hole 5 in a certain threading manner to form a number of adjustable suspension rings 8 on one side of the fixed plate 1, and on the other side of the fixed plate 1 side to form a double pressurized self-locking knot 9; the tail end of the suture line segment 2 passes through the knot head 10 of the double pressurized self-locking knot 9, and the adjustable suspension ring can be adjusted by pulling the tail end of the suture line segment 2 8 in length.

[0028] Such as figure 2 As shown, the double pressurized self-locking knot 9 includes a first locking node 91 and...

Embodiment approach

[0031] As a preferred embodiment of the present invention, the fixed plate 1 is a slender body with arc-shaped ends, and the arc-shaped ends are respectively provided with a first end through hole 6 and a second end through hole 7, respectively. The traction line 3 and the loop loop line 4 are set; the material of the fixed plate 1 is stainless steel, titanium alloy or PEEK, the length is 8-16mm, the width is 2-8mm, and the thickness is 0.5-3mm; The shape of the wire through hole 5 , the first end through hole 6 and the second end through hole 7 is circular, elliptical or regular polygon, and the diameter thereof is 0.2-3 mm.

[0032] As a preferred embodiment of the present invention, the material of the suture section 2, the puller thread 3 and the loop thread 4 is one of ultra-high molecular weight polyethylene, polyester or mixed braiding; the line of the suture section 2 The diameter is 0.2-2mm, and the length is 60-200cm.

[0033] Such as Figure 5 As shown, the applic...

Embodiment 2

[0035] Such as Figure 4 As shown, the present embodiment provides another fixing plate and suture perforation method. The fixing plate 1 is provided with six suture through holes 5, wherein four of the suture through holes 5 are regular quadrilateral vertices, and the other two The suture thread through holes 5 are respectively located on both sides of the regular quadrilateral, and their centers are located on the transverse central axis of the regular quadrilateral. The suture line segment 2 passes through the suture line through hole 5 in a certain threading manner, and forms a spanning part 11 on the beam between the suture line through holes 5 on both sides of the regular quadrilateral respectively, and the suture line segment 2 The tail end passes through the top or bottom of the spanning part 11 to form a second locking node, and passes through the knot 10 to form a first locking node; and forms four adjustable suspension rings 8 on the other side of the fixed plate 1,...

Abstract

The invention relates to a lifting ring fixing plate device with an adjustable length. The lifting ring fixing plate device with adjustable length comprises a fixed plate, a suture line segment, draught lines and loop turning lines, wherein the draught lines and the loop turning lines are arranged at the two ends of the fixed plate respectively; the fixed plate is provided with a plurality of suture line through holes matched with the shape of the fixed plate; the suture line segment penetrates through the suture line through holes in a certain threading manner to form a plurality of adjustable lifting rings on one side of the fixed plate and a double pressurizing self-locking knot on the other side of the fixed plate; the tail end of the suture line segment penetrates through a knot of the double pressurizing self-locking knot; and the length of each adjustable lifting ring can be adjusted by pulling the tail end of the suture line segment. The lifting ring fixing plate device with the adjustable length can be adapted to surgical channels with different lengths by adjusting the lengths of the adjustable lifting rings; the double-pressurizing self-locking knot can effectively ensure that the a ligament cannot have the fallback phenomenon in the operation process and lowers the risk of postoperative disengagement of the self-locking knot; and different numbers of the suture linethrough holes of the fixed plate can be matched with the suitable threading modes, so that the overall mechanical performance of the system is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a length-adjustable suspension ring fixing plate device. Background technique [0002] The anterior cruciate ligament (ACL), also known as the anterior cruciate ligament, cannot heal itself after it ruptures and cannot directly suture the two ends of the rupture. Therefore, 100,000 patients undergo ACL reconstruction every year. The principle of ACL reconstruction is very simple. Bone holes are drilled at the femoral and tibial ends of the knee joint, and then the replacement ligament is introduced into the joint, and the new ligament is fixed on the femoral and tibial ends at the proper position. In ACL surgery, a sling plate system is used that suspends the ligament replacement and secures it to the femur and tibia. At present, the ring plate system used for ACL reconstruction can be roughly divided into two categories, one is the ring plate system with adjustable ring...
