Description

Technical Field

[0001] This utility model belongs to the technical field of dental barb suture processing and positioning devices, specifically relating to a barb suture processing and positioning device. Background Technology

[0002] In dental procedures, such as gingival surgery and oral mucosal surgery, it is necessary to cut or separate tissues, and then align and fix the cut or separated tissues, which requires suturing. Barbed sutures are a type of suture material used to suture separated tissues. Their surface has tiny barbs. When the suture is pulled in, the barbs will evenly distribute the tension to the surrounding tissues, reducing damage to soft tissues such as gums and mucosa. During the production process of barbed sutures, the surface needs to be engraved or surface treated. This requires fixing the produced spool into a tube, then stretching one end of the barbed suture on the spool and pulling continuously to process the suture.

[0003] When stretching the suture on the spool, as the thickness of the barbed suture wound on the spool changes, the barbed suture near the spool becomes unstable and may be in a wobbly state, affecting the stability of the stretched barbed suture and even causing the barbed suture to break. The lack of a design for the barbed suture is a shortcoming.
