Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to ligament system of rebuilding.
Background
In anterior and posterior cruciate ligament repair surgery for knee joints, bone tunnels need to be drilled in the tibia and the femur, and then ligament grafts are fixed in the communicated tunnels. The tibial end is fixed by an interface screw or a belt loop titanium plate, and the femoral end is usually fixed by a transverse nail, an interface screw and a belt loop titanium plate. The use of a strap titanium plate for suspension fixation of the femoral end is considered the gold standard for current ACL reconstruction.
The published data shows that minimal cyclic displacement can be obtained by EndoButton-CL comparison with the competitive products in the femur end suspension fixation method. The reason for analyzing the minimum cyclic displacement is mainly to adopt a non-woven core rod type structure, but because of adopting a non-woven form, loose high-strength filaments also have a certain cutting effect on the transplanted tendon during ligament movement. Patent CN 208693352U improves the above structure, and uses an elliptical filament, braided outer sleeve to avoid the above mentioned cutting effect, but because its central core rod is partially preset, the integrity of braided ring is not strong, so there is room for improvement of the cyclic displacement of loop in ligament reconstruction system.

The utility model relates to a ligament system of rebuilding includes: the sewing thread plate, the coil, the traction thread and the turner thread. The sewing thread plate is provided with an opening for winding the coil, the traction thread and the turning loop thread; the coil comprises a hollow braided sleeve and a solid core rod, the hollow braided sleeve is in an annular shape formed by a first portion and a second portion in a surrounding mode, the inner diameters of the first portion and the second portion are different, and the length of the solid core rod is larger than that of the hollow braided sleeve.
Preferably, in the above technical solution of the ligament reconstruction system, the hollow braided sleeve has an annular shape surrounded by a first portion and a second portion, and an inner diameter of the first portion is larger than an inner diameter of the second portion.

Detailed Description
The utility model provides a ligament is rebuild the system, especially coil in the ligament is rebuild the system, this coil contains the hollow sleeve pipe of weaving and is located its inside solid plug, the hollow sleeve pipe of weaving is woven and is formed a continuous ring, weave the intraductal coiling of sleeve through solid plug and act as the prefabricated inner core in the current mode, avoid solid plug filament to the muscle tendon tissue effect of splitting for solid plug and hollow sleeve pipe wholeness of weaving is stronger, the circulation displacement is littleer, mechanical properties performance is better, reach better ligament and rebuild the effect.
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model relates to a ligament system of rebuilding includes: a suture plate 3, a coil 4, a traction thread 2 and a turning loop thread 1, wherein the coil 4 is used for winding a graft 5. The sewing thread plate is provided with an opening for winding the coil, the traction thread and the turning loop thread; the coil comprises a hollow braided sleeve 6 and a solid core rod 7, the hollow braided sleeve is in an annular shape formed by a first part and a second part in a surrounding mode, the inner diameters of the first part and the second part are different, and the length of the solid core rod is larger than that of the hollow braided sleeve.
The suture plate is of a sheet-shaped central opening structure, can be made of titanium alloy, PEEK, carbon fiber, nickel-titanium alloy, hard alloy or other composite materials, is prefabricated into a fixed shape in a casting, forging, stamping or extruding mode and the like, can obtain personalized data by scanning the shape of the cortical bone at the femoral end of a patient, and can be printed and customized in a 3D mode to fit the shape of the cortical bone.
The hollow braided sleeve may be a ring formed by a first portion and a second portion which have the same length, and the lengths of the first portion and the second portion may be different from each other, the inner diameter of the first portion is larger than the inner diameter of the second portion, the outer diameters of the first portion and the second portion are the same, and the portion of the solid core rod, which is longer than the hollow braided sleeve, is located in the first portion. The length of the solid core rod is 1-4 times of the length of the hollow braided sleeve.
The first part of the coil is a section C, the second part of the coil is a section D, the coil is a fixed-length coil which cannot be adjusted, and the coil is made of high polymer materials such as polyethylene terephthalate, polyethylene and polyester materials.
The preparation process is shown in fig. 2 and 3, the coil is a material comprising a hollow braided sleeve and a solid core rod in an original state, and the coil can be made of wires with round or oval interfaces and with or without cores inside. The hollow braided sleeve is divided into a C section and a D section, the outer diameters of the C section and the D section are the same, and the inner diameter of the C section is larger than that of the D section.
When the winding is started, the hollow braided sleeve section is wound into a circle, the openings A, B are connected, the distal end of the solid core rod enters the braided sleeve from the opening A, then the solid core rod is wound for a circle and a half to the end in the braided sleeve, and the proximal end, the middle part and the distal end of the solid core rod can form a braided structure with the braided sleeve or are fixed in a knitting mode. The preparation method is different from the existing method, and the solid core rod is wound in the braided sleeve to serve as the prefabricated inner core in the existing method, so that the inner core and the braided sleeve are stronger in integration and better in mechanical property performance.
