The medical scalpel is usually composed of two parts: one is the surgical blade and the other is the handle. Only when the blade is installed on the handle can it be called a scalpel. If it is not combined, it belongs to two kinds of medical instruments, the surgical blade and the handle. Let's first understand a part of the scalpel, the scalpel handle.
General scalpel handles are divided into:
1. 3 # tool handle is commonly called small-sized tool handle. It is used with 10-15 # blades. It is often equipped with 10 # blades (inside knives) for cutting superficial tissues.
2. 4 # handle is used with 20-25 # blade, and it is often used with 20 # blade (skin knife) to cut the skin.
3. 7 # tool handle is used with 10-15 # blades, and 15 # blades (deep knives) are often used to cut deep and fine tissues.
4. 9 # knife handle is used with 10-15 # blades. It is often used with 15 # blades (small knives) for ophthalmology, otolaryngology, etc.
From the above description, we can know that the two parts of the scalpel are indispensable. Only when the two parts are combined and used together can the best surgical purpose be achieved. Of course, I believe that with the continuous progress of medical level, I believe that the types of scalpel handles will be more diverse and the uses will be more extensive.
