Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, the disposable scalpel comprises an injection molding scalpel handle 1 and a metal blade 2, wherein the injection molding scalpel handle 1 and the metal blade 2 are connected through an injection molding integrated structure.
The injection molding scalpel comprises an injection molding scalpel handle 1 and a metal blade 2, wherein the injection molding scalpel handle 1 and the metal blade 2 are integrated into a whole through an injection molding process, the injection molding scalpel is disposable and disposable, the metal blade 2 is firmly connected and fixed on the injection molding scalpel handle 1, and the metal blade 2 is not easy to fall off, break and the like.
The injection molding scalpel handle 1 can be made of plastic materials or resin materials, has a prominent specific color such as orange, green or purple, preferably has a blue color commonly used by public security, and the specific color is favorable for forming a sharp contrast between the disposable scalpel and a working environment, is easy to be quickly found and searched by a forensic doctor and is not easy to accidentally injure the forensic doctor; in addition, the surface of one end of the injection molding cutter handle 1, which is far away from the metal blade 2, is provided with words such as 'special legal medical expert' to highlight the special public security legal medical expert. The metal blade 2 may be, but is not limited to, a carbon steel material or a stainless steel material.
As shown in fig. 3, the thickness of the metal blade 2 is about 0.50 ± 0.05mm, and the metal blade includes a blade portion 22 for cutting and a connecting portion 21 for connecting the injection molding tool holder 1, and the blade portion 22 and the connecting portion 21 are connected by a metal integrated structure.
The connecting portion 21 is provided with at least one injection molding hole 24, and when injection molding is performed, an injection molding material part forming the injection molding knife handle 1 is filled in the injection molding hole 24, as shown in fig. 2, so that the molded injection molding knife handle 1 is partially embedded into the injection molding hole 24, and the stability of connection between the metal blade 2 and the injection molding knife handle 1 is improved.
The upper and lower width of the knife edge part 22 is the shape with two small ends and a large middle part, so that the knife edge 23 is of an arc structure with a convex middle part, and the forensic doctor can dissect the corpse from different angles by using the disposable scalpel.
The knife point 26 at the end of the knife point 22, which is far away from the injection molding knife handle 1, is a passivation structure, so that the integrity of biological tissues can be ensured when different biological tissues which are attached together are separated at the knife point 26 for forensic use.
