Needle tip batch grinding equipment for medical suture needles

Abstract

The invention relates to the field of medical equipment production and manufacturing, in particular to needle tip batch grinding equipment for medical suture needles. The needle tip batch grinding equipment for the medical suture needles comprises a piece fixing mechanism, a rotating mechanism, a cutting mechanism, a collecting mechanism and a supporting mechanism; the piece fixing mechanism comprises four piece fixators; the four piece fixators are all arranged vertically and are of the same structure; an outer shell, a first motor, a first gear, a second gear, a limiting rod and an electriccylinder are arranged on each piece fixator; the cutting mechanism comprises three cutters; the three cutters are of the same structure; and a screw rod sliding table, a moving body, a second motor, agrinding wheel, a water spraying head and a baffle plate are arranged on each cutter. According to the needle tip batch grinding equipment for the medical suture needles provided by the invention, the medical suture needles can be ground quickly at a plurality of stations and are ground circularly; the heat produced by the suture needles and the grinding wheels in a grinding process is cooled; the production efficiency is high; the equipment grinding is safe and stable; manual operation is reduced; and meanwhile, a grinding process is simplified.

Description

Technical field [0001] The invention relates to the field of production and manufacturing of medical equipment, in particular to a device for sharpening the tip of a medical suture needle in batches. Background technique [0002] Up to now, there have been three generations of medical suture needles. The first generation of traditional eye needles: like curved sewing needles, needle punching holes, and fork-shaped slots in the tail. The first generation is mainly used for non-absorbable sutures. The second-generation slotted needle: the tail is slotted and the needle and thread are connected. It is mainly used for suturing in less demanding parts or thin sutures. The third-generation drilling needle: the tail is drilled and the needle and thread are connected. It is mainly used for minimally invasive Suture the wound. [0003] Medical suture needles are mainly used for surgical sutures. They are mostly made of stainless steel wire drilled or slotted at the end of the needle. The s...

Problems solved by technology

[0005] When grinding medical suture needles, the traditional grinding of medical suture needles uses a single needle grinding equipment. When grinding, the suture needles are placed in the grinding equipment for grinding, and the grinding efficiency is low. When grinding, it needs to be manually locked and fixed. The position of the suture needle, cutting and grinding medical suture needles also need manual control of the grinding speed and angle, which requires skilled workers to complete. Traditional medical suture needle grinding not only requires a lot of manpower, but also requires high technical requirements for operators. Medical suture needles are generally made of metal materials. When medical suture needles are in contact with grinding equipment, high temperatures will be generated. When grinding medical suture needles, the temperature may affect the grinding effect of medical suture needles. General medical suture needles The grinding equipment does not have equipment to cool down the equipment and medical suture needles, so it is necessary to design a device that can grind multiple medical suture needles at the same time. The grinding equipment can cool down the medical suture needles, and the grinding waste can be collected centrally and can be continuously polished.
