Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment processing, in particular to a punching connection tool for medical suture needles. Background Art

[0002] Medical suture needles are mainly used for surgical sutures. They are mostly made of stainless steel wire with holes or grooves drilled at the needle tail. The surface is polished and electrolytically treated, and should be very smooth. The needle type is divided into round needles, angle needles, shovel needles, straight needles, etc. according to actual needs. The arc is divided into 1 / 2, 3 / 8, etc. according to actual needs. The production process is very complicated and it is a high-tech product. Fine drilling even uses laser drilling technology. Medical suture needles play an important role in surgical operations. The connection strength between medical suture needles and sutures has very high requirements. If the connection strength is not enough, they cannot be used.

[0003] When an existing medical suture needle is connected to a suture, the outer circumference of the tail hole of the medical suture needle is usually rolled in a circular manner to make the tail hole smaller to clamp the suture. For example, the Chinese patent medical suture needle with patent application number CN202120970610.X sets a threading hole through the tail of the medical suture needle. The threading hole is a drilled hole facing the inside of the needle body from the tail end of the needle. The suture is set in the threading hole; a clamping structure is set on the hole wall of the tail threading hole near the position of the suture; the clamping structure is a concave pit or a punching hole from a certain position on the hole wall, radially from the outside to the threading hole, and the inward edge of the concave pit or the punching hole produced by the punching will press against the suture and may penetrate into the suture to compress the suture. The clamping structure can provide a good connection strength between the medical suture needle and the suture. The clamping structure is recessed inward from the threading hole at the tail of the medical suture needle, and burrs will not be generated on the outer surface of the medical suture needle, which can avoid burr damage to the sutured tissue. However, traditional methods similar to the above-mentioned patents generally use manual pressing, and the punching force and position are not fixed, resulting in unstable needle and thread connection strength. For this reason, we propose a stamping connection tooling for medical suture needles. Utility Model Content
