Embodiment Construction

[0060] The present invention will be further described below in conjunction with accompanying drawing:

[0061] Such as Figure 1-13 As shown, a device for forming a fishbone on a suture, including a hot-melt mechanism ( Figure 1 ~ Figure 3 ) and molding mechanism ( Figure 8 and Figure 9 ), the hot melt mechanism will suture the main thread 1501 ( Figure 15 ) and the herringbone line 1502 ( Figure 15 ) heat-melt to form a whole, and flatten the herringbone line on both sides to a set thickness; the forming mechanism cuts the flattened herringbone line part to obtain a suture with a herringbone structure. The present invention sequentially completes the primary hot-melt integral molding of the suture main line and the side line of the herringbone line and the final cutting and molding of the herringbone structure through the hot-melt mechanism and the forming mechanism.

[0062] In the present invention, the hot-melt mechanism and the molding mechanism both include an...

Abstract

The invention discloses a device and method for forming a fishbone on a suture. The device includes a hot-melting mechanism and a forming mechanism, a main suture of the suture and fishbone edge sutures arranged symmetrically on two sides of the main suture in parallel are hot-molten through the hot-melting mechanism to form a whole, and the fishbone suture edge sutures on two sides are flattenedto a set thickness; and the forming mechanism cuts the flattened fishbone suture edge sutures to obtain the suture with a fishbone structure. The method and device provided by the invention can complete the low-temperature deformation processing of a suture under a nitrogen environment to form the fishbone-shaped suture, so that the processing efficiency is improved, the processing quality is ensured, the use of organic solvents is avoided, and the safety and environmental protection of the preparation environment are improved; and at the same time, a corresponding mold can be designed as needed by using the method provided by the invention, the size of the fishbone is not limited, and the processing flexibility is greater.

Description

technical field [0001] The invention relates to a device for forming a fishbone on a medical suture, in particular to a device and a method for forming a fishbone on a suture. Background technique [0002] Suture thread is widely used in the suturing of the wound of operation and trauma, and one end of suture thread is tied on the surgical needle, and surgical needle pulls suture thread through tissue to make wound suturing and tissue fixed connection together to heal and regenerate, and at present Most sutures need to be tied with one or more knots to fix the sutures. Knotting increases the operation time and has a serious impact on some operations. For cosmetic surgery, laparoscopy and endoscopic examination, general sutures are difficult competent. [0003] The fishbone suture is a fishbone shape formed on the suture. The surgical needle pulls the one-way fishbone suture through the tissue in one direction, but the tissue suture moves in the opposite direction, so that t...
