Surgical knife blade

Abstract

The invention relates to the technical field of anesthesia medical instruments. The surgical knife blade comprises a first blade part, a second blade part and a third blade part, the first blade partis arranged towards the front end of the blade, the second blade part and the third blade part are arranged towards the upper side and the lower side of the blade respectively, the first blade part comprises a first cutting edge part towards the front end of the blade, and the first cutting edge part is arranged in a smooth curve mode; the second blade part comprises a second cutting edge part facing the upper side direction of the blade, the second cutting edge part is arranged linearly, and the end part of the second cutting edge part is retracted inwards to form a cutter point; the third blade part comprises a third cutting edge part facing the lower side of the blade, and the third cutting edge part is of a crescent structure with the tip facing downwards. The surgical knife blade hasthe beneficial effects that the surgical knife blade can be used for cutting various tissues, is convenient to operate, does not influence an existing surgical cutting method, and is simple to use, sothat the fluency of surgical actions is greatly improved, the surgical efficiency is improved, and the risk of a patient is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of anesthesia medical instruments, specifically a surgical blade. Background technique [0002] A scalpel usually consists of a blade and a handle. The blade usually has a cutting edge and a mounting groove docked with the handle of the scalpel. The material is usually pure titanium, titanium alloy, stainless steel or carbon steel, and is generally disposable. During dissection, the blade is used to cut skin and muscle, the tip is used to clean blood vessels and nerves, and the handle is used for blunt dissection. Choose the appropriate type of blade and knife handle according to the size of the wound. Because the ordinary scalpel has the characteristic of "zero" damage to the tissue after cutting, it can be used in various operations, but the wound bleeding is active after cutting, so it should be used in operations with a lot of bleeding in a controlled manner. [0003] For the...

Problems solved by technology

[0003] For the type of tissue that needs to be cut in the operation, it is often necessary to use different types of blades. For example, for smooth tissues (skin, muscle, periosteum), etc., blades with wide and smooth blades are often used. For blood vessels, nerves, gastrointestinal tract and heart Tissues often need to use sharp blades with sharp and thin blades, and sharper blades are needed to cut connective tissue and fibrous tissues such as knee joints. Therefore, in some operations, the operator needs to frequently change the scalpel to perform the operation. The inconvenience caused by the operation, and the risk of infection for the patient due to repeated replacement of the scalpel, it is particularly important to invent a surgical blade that can be applied to a variety of situations
