Knitting technology for surgery

Knitted fabrics are widely used in surgery for applications and textile implants including, for example suture materials, meshes for hernia repair, artificial ligaments and knitted grafts along with fabrics for heat exchangers and oxygenators. The versatility of Comez knitting machinery allows their users to create numerous types of textiles that meet the many requirements in terms of strength, flexibility, durability and stability of these articles.

Containment netting support for hernia

Thanks to surgical interventions, the abdominal or inguinal wall affected by hernia can be reconstructed with a medical textile implant. The hernia repair mesh must adapt to the area in which it is implanted, while providing lasting support over time. Knitted textile implants made with absorbable and non-absorbable materials guarantee an optimal response to these needs.

Non-absorbable mesh for uterine prolapse

Numerous types of suture netting can be produced on Comez knitting machines, featuring maximum flexibility and high resistance, and capable of guaranteeing textile implant stability. The mesh’s large-pore structure allows internal tissue growth and, consequently, the optimal integration of the implant at the surgery site.

Mesh for hernia treatment

Hernia repair is one of the most common surgical procedures, affecting several areas. The treatment of hernias requires the use of lightweight netting that ensures greater patient comfort regardless of the surgical technique employed. Large-holed mesh allows rapid fabric integration, ensuring the implant’s lightness, softness and elasticity. Comez provides manufacturers with highly efficient, versatile production machinery for meshes in the treatment of all types of hernia.

Artificial ligament

Artificial textile ligaments are intended for the augmentation and reconstruction of injured ligaments located in different parts of the body, and are designed to simulate the behavior of natural ligaments. These applications consist of a polyester material featuring a special knitted texture in the central part, achievable using crochet machines. The finished product’s form and dimensions can vary based on the customer’s needs and intended surgical treatments.

Blood filtration fabric

Membrane filters have become established in the medical sector as solutions for artificial lungs, blood oxygenators and heat exchangers. These devices contains a fabric consisting of microcapillaries linked by crochet technology. Listening to our customers’ needs and providing the necessary synergies with available technologies within our group has led us to define a specific configurations of electronic knitting machines for the production of blood filtration fabrics.

Knitted vein and arteries grafts

Advanced cardiovascular surgical techniques allow the replacement of damaged or malfunctioning arteries and veins with textile vascular grafts. Knitted grafts are made of synthetic material and designed with an anti-stretch weave to avoid the risk of fraying or wear at the ends. Artificial textile veins can be produced in different designs and diameters, but the main distinction is between linear and bifurcated knitted grafts.
