Vävnadsnålar

Vävnadsnålar, also known as tissue needles, are specialized surgical instruments used in various medical procedures. Their primary function is to facilitate the precise manipulation and suturing of tissues. These needles are designed with specific characteristics to ensure optimal performance during surgery, often requiring a combination of strength, sharpness, and appropriate curvature for different anatomical locations and tissue types.

The design of a vävnadsnål typically includes a sharpened point, a body, and an eye or attachment point for surgical thread, known as suture material. The point can vary in shape, such as cutting points for tough tissues or taper points for delicate structures. The curvature of the needle body is also critical, allowing surgeons to access difficult-to-reach areas and achieve the desired angle for suturing. Common shapes include half-circle, quarter-circle, and straight needles, each suited for specific surgical tasks.

Vävnadsnålar are manufactured from high-quality stainless steel or other durable alloys to prevent corrosion and ensure sterility. They are often supplied pre-attached to a suture material, forming what is known as a swaged needle, which minimizes tissue trauma compared to older eyed needles. The selection of the appropriate vävnadsnål depends on factors such as the type of tissue being sutured, the size of the surgical wound, and the surgeon's preference. Their use is fundamental in closing surgical incisions, repairing damaged organs, and securing implants, playing a vital role in successful surgical outcomes.
