Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment production and manufacturing, in particular to a needle tip grinding device. Background Art
[0002] Medical suture needles have developed three generations. The first generation of traditional eye needles: like curved sewing needles, spring-type hole needles, with a forked slot at the tail, the first generation is mainly used for non-absorbable sutures, the second generation of slotted needles: slotted at the tail, needle and thread connected, mainly used for sutures of less demanding parts or thinner sutures, the third generation of drilling needles: drilling holes at the tail, needle and thread connected, mainly used for sutures of minor injuries. Medical suture needles are mainly used for surgical sutures, mostly made of stainless steel wire with holes or slots at the tail of the needle, 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, and the curvature 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, and fine drilling even uses laser drilling technology. Features of medical suture needles: high-quality stainless steel, the needle body can remain unbroken after multiple bends; good puncture force, the needle body is coated to make it smoother and easier to puncture skin tissue than other suture needles; the needle tip remains sharp after passing through human tissue many times; advanced heat treatment technology keeps the steel at a considerable hardness and is not easily deformed during use; advanced needle tail laser longitudinal punching technology is used to make the needle and thread connection almost integrated, making it a truly damage-free suture needle and thread; Angle needle type: contrary to the regular triangle needle type of other brands of sutures, a less traumatic reverse triangle needle type is used; in line with industry standards for medical suture needles.
[0003] Traditional medical suture needles are polished using a single needle polishing device. During polishing, the suture needle is located in the polishing device for polishing, and the polishing efficiency is low. During polishing, the position of the medical suture needle needs to be manually locked and fixed. Traditional medical suture needle polishing not only requires a large amount of manpower, but also has high technical requirements for the operator. The polished medical suture needles are generally made of metal materials. When the medical suture needles come into contact with the polishing device, very high temperatures will be generated. When the medical suture needles are polished, the temperature may affect the polishing effect of the medical suture needles. Manual polishing is inconvenient, so a needle tip polishing device is proposed to solve the above problems. Utility Model Content
