Titanium MIM Surgical Tools
Surgical tools require high strength, low blood contamination, and the ability to implement aggressive sterilization procedures. The design flexibility of MIM technology can meet most surgical tool applications, and it also has process advantages. The manufacture of various metal products is gradually replacing the traditional production technology as the main manufacturing method.

Surgical Tools
Surgical tools require high strength, low blood contamination, and the ability to implement aggressive sterilization procedures. The design flexibility of MIM technology can meet most surgical tool applications, and it also has process advantages. The manufacture of various metal products is gradually replacing the traditional production technology as the main manufacturing method.
Qinhuangdao Zhongwei Precision Machinery Co., Ltd. uses MIM technology to develop a titanium alloy claw, which is produced by titanium alloy injection molding process with a density of more than 8.5g/cm3. It can be used to grasp objects in the human body during surgery, and has the function of tweezers . Its design is quite complex and requires high production precision.
Forming using MIM technology followed by sintering allows high tolerance levels to be achieved without the need for extensive post-processing, which would otherwise destroy the alignment and geometry of the jaws.
It is difficult to produce such complex-shaped stainless steel jaws by casting or machining methods, requiring a long production cycle and high cost. Using MIM technology to manufacture can save 60% of the cost.
Disposable surgical tools need to develop a process that can be mass-produced at low cost. Zhongwei Precision Machinery Co., Ltd. uses MIM technology to produce a shaft assembly, which is used in a new type of disposable surgical instruments. The cost is only the use of Swiss 1/4 ~ 1/5 of the CNC machine tool processing, the density is 7.5 g/cm3, the ultimate tensile strength is 1190MPa, the yield strength is 1090MPa, the elongation is 6.0%, and the maximum hardness is 33 HRC.
The manufacturing process of this product is as follows: first, use MIM technology to form two shaft parts with a length of 178mm, then laser weld the two parts, and then carry out subsequent machining and heat treatment. In order to achieve better tolerance requirements, it is necessary to spray Pellets and passivation treatments.
The use of titanium in surgical instruments
Titanium alloys only began to be used as materials for surgical instruments in the 1960s.
The most obvious advantage of titanium is its superior strength. It has almost the same tensile strength as carbon steel and is 100% corrosion resistant, but it is lighter than stainless steel, about 40% lighter for the same volume.
Titanium is the perfect material for surgical instruments and implants because it is biocompatible and can fuse with human bones. As a result, it has become the metal of choice for orthopaedic rods, needles, plates and dental implants.
Titanium is more heat-resistant than stainless steel, can withstand high temperatures of 430°C, and it expands and contracts less when heated and cooled.
Titanium is a multifunctional metal. Depending on the performance required for surgical instruments, grade 1 titanium or grade 2 titanium can be selected as the material of manufacture. Both types of titanium can be easily machined, welded and cold worked.
In general, titanium is a hard and durable metal that has become a common material in the manufacture of various medical devices.
