 Disposable ceramic scalpel and preparation method thereof

 Technical field

 The present invention relates to a scalpel, and more particularly to a disposable ceramic scalpel and a method of preparing the same, which belong to the field of medical device technology. Background technique

 Existing scalpels or surgical scissors are made of stainless steel. Although doctors and patients are already familiar with them, they do not know the defects of existing scalpels or surgical scissors. The metal knife is the chief culprit of the scar. The metal knife is cut into a zigzag shape. Although it is difficult to distinguish by the naked eye, the wound heals slowly, is prone to sputum, and has metal diffusion, contaminates the wound, and produces pigmentation. Today's beauty doctors can use dozens of times even a single steel knife. The sharpness of the knife can be imagined. Therefore, existing steel scalpels and surgical scissors have not been suitable for the needs of surgery.

 Because the metal knife has a metal diffuser, it is easy to contaminate the wound, and the metal knife blade has a limited sharpness, and the incision is jagged. Although we can't see it in the human eye, in fact, the wound is slow to recover and it is easy to leave a slight scar.

 From the current development trend of scalpels, steel knives will gradually be eliminated due to their physical and chemical properties and various drawbacks in the surgical process. Currently, the best scalpels are diamond knives, but the price is too expensive. Therefore, there is an urgent need to develop a new type of practical scalpel and surgical scissors that can achieve the diamond knife effect. Summary of the invention

The technical problem to be solved by the present invention is to provide a disposable ceramic scalpel and a preparation method thereof for solving the above technical problems, and an embodiment of the present invention provides a disposable ceramic scalpel, which uses a ceramic material, including a cutter head and The handle is fixed on the handle, the ceramic material is Zr0 ₂ and ΥΛ, the handle is provided with an anti-slip zone, and the lower end of the shank is provided with a small hole.

 A protective cover is provided on the cutter head.

 The above-mentioned single-use ceramic scalpel is prepared by the following steps:

 51. Lead qualified blanks

52. Sticky plate: Place the blade neatly on the special workpiece plate, and put it into the periphery of the blade with paraffin water. Bonding the blade after cooling;

 The country of the cutting machine is 0. 02 country; the amount of the tool is 0. 02 country;

 54. Lower plate: heat the workpiece plate to remove the blade;

 55. Cleaning blade: first boil a pot of boiling water, boil the blade in boiling water for 2 minutes, then remove the blade, rinse it again with water to dry it;

 56. Dry the blade: Place the cleaned blade on the cloth to dry.

 57. After cleaning the blade: Place the blade neatly on the special workpiece plate on the lower plate, with the polished side facing down, place the paraffin water into the periphery of the blade, and then cool the bonded blade;

 The slab is 0. 02ram; each time the amount of the feed is 0. 02ram;

 59, lower plate: heat the workpiece plate, remove the blade;

 510. Washing and drying: First boil a pot of boiling water, boil the blade in boiling water for 2 minutes, then remove the blade, rinse it again with clean water and dry it on the dry cloth;

 511, inspection, qualified blanks, into the warehouse, defective products, warehousing.

 512. After the secondary blade is opened, the back of the knife is sharpened, and the fine edge is opened, the blank is obtained;

 513, inspection, smelting blanks, defective products, warehousing or repair.

 514. Lead the qualified blank, clean the blade, package the blade, get the finished product, put the packaged blade into the warehouse, and wait for delivery.

 The invention has the following beneficial effects:

 1) Sharpness: The first condition for making a knife is high hardness. The hardness of the steel knife is Vickers HV700, and the hardness of the ceramic knife is HV1100; therefore, the ceramic knife is sharper than the steel knife.

 (2) Abrasion resistance: Because the hardness is high, it is wear-resistant; the wear resistance is 60 times that of the steel knife, it can be said that it will never wear, and it will be sharp forever; the steel knife will be used for a long time, the surface will be dull, and the ceramic knife will wear. , can always maintain a bright natural color.

 (3) Good histocompatibility: Zirconium oxide ceramic materials are high-performance ceramic materials with high technology content. They are new materials developed to solve the problems of aerospace, aviation and military. Ceramic scalpels and surgical scissors and human tissues. Good compatibility and fully meet the surgical requirements.

 The technical problems, the technical solutions, and the advantages of the present invention will become more apparent from the following detailed description.

The present invention provides for the existing deficiencies as shown in FIG. 1 and FIG. 2: a single-use ceramic scalpel, the whole knife is made of Zr0 ₂ and Y ₂ 0 ₃ , and includes a cutter head 1 and a handle 2, and the cutter head 1 is fixed at On the handle 2, an anti-slip zone 3 is provided on the handle 2, and a small hole 4 is provided at the lower end of the shank 2 to facilitate the hanging of the cutter. The protective sleeve 5 is placed on the cutter head 1, and the two are an interference fit, which not only ensures the sharpness of the cutter head, but also prevents the cutter head from being infected by bacteria. Ceramic scissors can also be used for surgical scissors or other sharp medical tools. Ceramic scalpels and surgical scissors are disposable. According to clinical requirements, the kit is used. It is sterilized at the factory and used at one time.
