Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a weaving design method for artificial ligaments of small joints. Background Art

[0002] Facet joint ligaments mainly include ligaments in the shoulder, elbow, wrist, ankle and other parts. In the early stages, people had a shallow understanding of ligament injuries in these parts and did not pay enough attention to them. As the number of patients increases, people have a deeper understanding of facet joint ligament repair, including: Acromioclavicular joint: The incidence of acromioclavicular joint injury accounts for 9% to 12% of shoulder injuries. The common injury mechanism is direct violent impact on the acromion when the shoulder joint is in adducted position. Indirect violence when the wrist or elbow is in extended position can also lead to acromioclavicular joint injury.

[0003] Wrist Joint: Giant cell tumors of the bone are the most common bone tumors of the distal radius, but other bone tumors can also invade this area, often invading the wrist joint and affecting its function. Traditional radial hemicarpal reconstruction often uses autologous fibula, which has some drawbacks, including progressive degeneration, wrist instability, and prolonged surgery.

[0004] Knee: Patellar ligament rupture is a relatively rare type of sports injury, often caused by high-energy sports injuries or direct violence. Early misdiagnosis is common due to residual function, with a misdiagnosis rate as high as 38%. Patellar ligament ruptures that persist for more than two weeks are considered old ruptures and often require patellar ligament reconstruction or reinforcement surgery.

[0005] Ankle: The ankle is a critical weight-bearing joint in the lower limb. Its unique anatomical structure makes it highly susceptible to injury during exercise. Ankle ligament injuries, commonly known as ankle sprains, are the most common limb ligament injuries. Consequently, the diagnosis and treatment of ankle ligament injuries have received significant attention from orthopedic and sports medicine professionals worldwide. While most patients with ankle ligament injuries have a satisfactory prognosis with conservative treatment, some still require surgical intervention.

[0006] Therefore, an artificial ligament for repairing small joints is particularly necessary. The current methods for repairing small joint ligaments include sutures and titanium plate repairs for shoulder joints. This repair requires the coordinated use of plates, buckles, and wires. The clinical use steps are cumbersome, and there are also situations where the plate cuts the wire. The small joint artificial ligament uses a special braid to form a soft acromioclavicular repair ligament. For the repair of wrist ligaments, patellar ligaments, and ankle ligaments, there are currently no dedicated repair ligaments, and sutures are generally used for repair. The present invention designs a weaving design method for small joint artificial ligaments that is more suitable for clinical use, which brings convenience to doctors and good news to patients. Summary of the Invention

[0007] In order to overcome the deficiencies of the prior art, the present invention provides a method for designing the weaving of artificial ligaments for small joints.

[0008] To achieve the above-mentioned purpose, a weaving design method for artificial ligaments of small joints is designed, which includes weaving. The weaving is made by warp yarns and weft yarns. The weaving form of the warp yarns includes one or more of a chain weave, a variable warp bias weave, and a variable warp pile weave. The weaving form of the weft yarns is a weft lining weave.

[0011] The width of the woven cloth is 30-60cm.

[0012] The longitudinal density of the woven fabric is 15-30 rows / inch, and the transverse density is 10-20 wales / inch. The warp yarn is woven in a chain weave or a variable warp bias weave, and is fully threaded or loosely threaded according to the position of the free silk thread required for weaving. The weft yarn is woven in a full-width weft insertion weave, and the weft yarn is selected according to the minimum weave unit.

[0013] The longitudinal density of the woven fabric is 15-30 rows / inch, and the transverse density is 10-20 wales / inch. The warp yarn weaving form uses a chain weave structure or a variable warp pile structure, and is fully threaded or loosely threaded according to the position of the free silk thread required for weaving.

[0014] The longitudinal density of the woven fabric is 15-30 rows / inch, and the transverse density is 10-20 wales / inch. The warp yarn is woven in a chain weave or a variable warp-bias weave arranged in an axisymmetric manner, and is fully threaded or loosely threaded according to the position of the free silk threads required for weaving. The weft yarn is woven in a full-width weft insertion weave, and the weft yarn is selected according to the minimum weave unit.

[0015] The longitudinal density of the woven fabric is 15-30 rows / inch, and the transverse density is 10-20 wales / inch.

Furthermore, the pore size and porosity can be adjusted according to cell growth requirements, ensuring the safety and effectiveness of facet joint artificial ligaments.
