Surgical Instruments Material
Surgical instruments are made of a variety of materials, the choice of these materials is not only related to the performance and service life of the instruments, but also directly affects the smoothness and effectiveness of the operation, the following are the common materials used in the manufacture of surgical instruments and their characteristics, and I hope to be of help to you.

Stainless Steel
1、 surgical instruments overview:
stainless steel is a widely used material in surgical instruments, about 80% to 90% of the surgical instrument products are made of stainless steel.
Features:
Strong corrosion resistance: stainless steel contains at least 10% chromium, which can form a protective film on the surface and improve corrosion resistance.
Good mechanical properties: high strength and hardness, suitable for the manufacture of instruments that need to withstand a certain degree of pressure and wear, such as scissors, and hemostatic forceps.
Good processing performance: easy to process and polish, to meet the requirements of surgical instruments on precision.
2、 surgical instruments classification:
Martensitic stainless steel: such as 2Cr13, 3Cr13, 4Cr13, etc., commonly used in the manufacture of strength, hardness, rigidity, and abrasion resistance requirements of high instruments, such as tissue scissors, hemostatic forceps.
Austenitic stainless steel: such as 304, 316, etc., is commonly used in the manufacture of instruments requiring high corrosion resistance, such as suction tubes, and scalpel handles.

Titanium alloy
1、Overview of surgical instruments:
Titanium alloy occupies a place in surgical instruments with its lightweight, high strength, strong corrosion resistance, and other characteristics.
2、Characteristics of surgical instruments:
Lightweight: under the same volume, titanium alloy is about 40% lighter than stainless steel, which helps to reduce the doctor’s operating burden.
High strength: Tensile strength is similar to that of carbon steel but is lighter.
Good biocompatibility: harmless to the human body, suitable for the manufacture of surgical instruments implanted in the human body.
3、surgical instruments applications:
commonly used in ophthalmology, cardiothoracic surgery, neurosurgery, and other high-precision surgery, such as microsurgical instruments.
In summary, surgical instruments are made of various materials, and each material has its advantages and scope of application, when choosing the material, it is necessary to consider the specific needs of the operation and the environment of the instruments, if you want to know more about the surgical instruments and operating room equipment, you can pay attention to the Hongxiang Lide, at that time, there will be a special person in charge of the details of the difficulties for you to solve the puzzle.
