A matte gold medical suture needle

Abstract

This invention patent discloses a matte gold-plated medical suture needle, relating to the field of medical suture needle technology. It includes a needle body, a needle tip, and a needle tail, with the needle tip and needle tail located at opposite ends of the needle body. The needle body has a flattened portion, the needle tail has a suture hole, and the needle tip has a sharp conical shape. The key feature is that the needle body, needle tip, and needle tail are all coated with a matte gold plating layer; the total thickness of the matte gold plating layer is 30-75 μm. This invention patent provides a medical matte gold-plated suture needle by hot-dip galvanizing a stainless steel medical suture needle with a Zn-Ti-Ni plating solution, giving the stainless steel suture needle a matte gold plating layer, making the suture needle easier to identify by medical optical recognition systems and reducing visual fatigue for doctors.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a matte gold medical suture needle designed specifically for various clinical surgical procedures. Background Technology

[0002] Currently, mainstream medical suture needles are mainly used for surgical suturing. They are mostly made of stainless steel wire, pressed into shape, with holes or grooves drilled at the tail. The surface is polished and electrolytically treated. Needle types are categorized according to actual needs: round needles, angled needles, curved needles, and straight needles. Curved needles are further categorized by their curvature, such as 1 / 2, 3 / 8, and 5 / 8. Existing medical suture needles exhibit excellent performance in corrosion resistance, biocompatibility, strength, toughness, sharpness, and cost-effectiveness. However, with the development of medical science, medical devices with optical recognition equipment, such as medical imaging equipment and medical robots, are gradually playing a greater role in surgical procedures. Existing medical sutures will have severe glare under shadowless lamps, which will reduce the success rate of optical recognition equipment in recognizing medical sutures, easily cause visual fatigue for doctors, and thus prolong the operation time and increase the patient's pain. Therefore, it is necessary to provide a new medical suture needle to solve the above problems. Summary of the Invention

[0003] The problem solved by this invention is to provide a matte gold medical suture needle that can significantly improve the success rate of optical devices in recognizing suture needles, reduce doctors' visual fatigue, thereby shortening the operation time and ultimately alleviating patients' pain. The technical solution of this invention: A matte gold medical suture needle is provided, comprising a needle tip, a needle body, a needle tail, and a matte gold coating, wherein the matte gold coating covers the needle tip, needle body, and needle tail. The needle has a flattened structure on both the inner and outer sides, a hollow tail for connecting medical sutures, and a sharp conical tip. The matte gold plating is applied using a Zn-Ti-Ni plating solution, with a thickness of 30-75 μm. The main body of the medical suture needle is made of austenitic stainless steel, which is immersed in the Zn-Ti-Ni plating solution for 1.5 seconds at a temperature of 530 degrees Celsius. Cooling is achieved through direct water cooling with purified water. Compared with related technologies, the advantages and beneficial effects of the present invention are as follows: The matte gold medical suture needle provided by this invention is made of austenitic stainless steel, which inherits its high yield strength and is not easy to bend or break during puncture. The coating of Zn-Ti-Ni plating solution reduces the reflectivity of the austenitic stainless steel medical suture needle, improving the speed and probability of medical optical instruments recognizing the suture needle during suturing. Furthermore, the matte gold medical suture needle turns dark gold after contact with blood, making it more recognizable.

Detailed Implementation The present invention is further illustrated below with reference to examples of this application, but these examples do not limit the invention. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be discussed further in subsequent figures. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself. Example 1: Zn-Ti-Ni plating solution matte gold medical suture needles, description as follows: ① The main structure consists of a needle tip 1, a needle body 2, a needle tail 3, and a matte gold plating 4. The needle body 2 smoothly connects the needle tip 1 and the needle tail 3 on both sides. The matte gold plating covers the needle tip 1, needle body 2, and needle tail 3 (e.g., Figure 1 (As shown). ② The needle 1 consists of a conical cylindrical structure 101 and a sharp conical structure 102. The small plane of the conical cylindrical structure 101 and the bottom surface of the sharp conical structure 102 transition smoothly and are covered by the coating 4. The smooth transition from the sharp conical to the conical cylindrical structure makes it easier for the medical suture needle to pierce the skin and tissue (e.g., Figure 1 (As shown). ③ The needle body 2 has a flattened structure 201, which is smoothly connected to the needle tip 1 and the needle tail 3, and is covered by a coating 4. This flattened structure makes the medical suture needle easier to hold with various medical devices (such as...). Figure 2 (As shown). ④ The needle tail 3 consists of a threaded structure 301 and a hollow structure 302, with the threaded structure covered by a plating layer 4. The suture end is inserted into the hollow structure 302, and the threaded structure 301 is pressed by external force to fix the suture end (e.g., ...). Figure 3 (As shown). Austenitic stainless steel medical suture needle that did not develop a hollow 302 structure at the needle tail was immersed in a Zn-Ti-Ni plating solution for 1.5 minutes. During the immersion process, the plating solution was kept at a temperature of 520 degrees Celsius. After the immersion was completed, it was cooled directly in a water bath. The immersion process formed a Ti oxide film on the surface of the austenitic stainless steel suture needle, which appeared as a matte gold color after polishing. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims. This method can produce medical stainless steel suture needles that are easy to drill at the needle tail, crack-resistant, and protect the drill bit. The hardness of the drilled area at the needle tail is 215±12 HV, and the hardness of the needle body is 465±18 HV (e.g., Figure 3 As shown), the drilling cracking rate is 0.2%, the hole diameter accuracy is ±0.008mm, and there are no burrs.
