Description

Technical Field

[0001] The present application relates to the technical field of medical auxiliary tools, and in particular to a suture fixator. Background Art

[0002] Surgical sutures, also known as sutures, are primarily used for ligation and hemostasis, suturing, and tissue closure during surgical procedures. Sutures include absorbable and non-absorbable sutures. Absorbable sutures, such as catgut, synthetic sutures (PGA), and natural collagen sutures, can be absorbed by human tissue. Non-absorbable sutures cannot be absorbed by human tissue and need to be removed after the wound has healed.

[0003] At present, a Chinese patent announcement with announcement number CN213722181U discloses a suture fixing device, which includes a first clamping assembly, a connecting portion, and a second clamping assembly. Since the first clamping assembly is connected to the second clamping assembly through the connecting portion, and the first clamping assembly is provided with a plurality of first clamping areas for clamping sutures, and the second clamping assembly is provided with a plurality of second clamping areas for clamping sutures, the suture fixing device can clamp and fix multiple sutures at the same time when in use, and one end of the multiple sutures are respectively clamped and fixed by the multiple first clamping areas, and the other ends of the multiple sutures are respectively clamped and fixed by the multiple second clamping areas, so that the multiple sutures are distributed at intervals, and extracting one of the sutures will not cause the other sutures to move. It is more convenient to take the sutures during the operation, which is conducive to improving the surgical efficiency.

[0004] In actual use, it was found that the existing suture fixator could not limit the suture in the vertical direction when the opening and closing clamp body was opened. Due to the elasticity of the suture itself, it would bend when not compressed, which could easily cause the unused suture to fall out of the clamping area. Therefore, we proposed a suture fixator to solve the above problem. Utility Model Content
