Technical Field

The embodiment of the invention relates to the technical field of anesthesia medical instruments, in particular to a surgical blade.

Background

A scalpel is typically composed of a blade and a handle. The blade is usually provided with a cutting edge and a mounting groove butted with the scalpel handle, and the blade is usually made of pure titanium, titanium alloy, stainless steel or carbon steel and is generally disposable. When in dissection, the knife edge is used for cutting the skin and the muscle, the knife tip is used for repairing the blood vessel and the nerve, and the knife handle is used for blunt separation. The blade and the knife handle with proper models are selected according to the size of the wound. Because the common surgical knife has the characteristic of zero damage to tissues after cutting, the surgical knife can be applied to various operations, but the wound surface bleeding after cutting is active and the surgical knife is applied to the operations with more bleeding in a control mode.

For the tissue types needing to be cut in the operation, blades of different types are often needed, for example, for smooth tissues (skin, muscle, periosteum) and the like, a blade with a wide and smooth blade part is often used, for blood vessels, nerves, gastrointestinal tracts and heart tissues, a blade with a sharp and sharp blade part is often needed, and for cutting of connective tissues and fibrous tissues such as knee joints and the like, a sharper blade is needed, so that in some operations, an operator needs to frequently replace a scalpel to perform the operation, which causes inconvenience for the operation, and because the scalpel is repeatedly replaced, the infection risk of a patient is increased, and therefore, the invention of the surgical blade which can be suitable for various conditions is particularly important.
