Titanium and its alloys have many advantages as surgical implant materials, such as low density, high strength, good toughness, good biocompatibility, non-toxicity, low elastic modulus, good corrosion resistance, and low X-ray absorption rate Etc., thus occupying an increasingly important position in medical metal materials. Titanium and its alloys can be used for the repair and replacement of human hard tissues, for the repair of cardiovascular and soft tissues, and the manufacture of artificial organs. It is a special functional material closely related to human life and health. At present, it has become the metal material of choice for replacement or repair products such as artificial joints, artificial bones, broken bone fixators, spine correction rods, intramedullary nails, artificial heart valves, dental implants, and skulls.

  Here is an introduction to the medical implantation of nitinol products and porous titanium products

  Nitinol (Ti-Ni alloy)

Nitinol plate

  Ti-Ni shape memory alloy (nitinol sheets) is a new type of functional material. This functional material has a peculiar shape memory effect, superelasticity, fatigue resistance, wear resistance, corrosion resistance, and good biocompatibility. Therefore, the alloy is widely used in the medical field.

Nitinol sheets have been successfully used in orthopedic clinics, which has attracted the attention of orthopedic experts and clinicians, and is called “magic metal”. The deformation temperature of NTSMA used in clinical orthopedics is 0℃~5℃, and the recovery temperature is 37℃. After fixing the fracture with NTSMA material, it is heated under body temperature or hot saline wet compress to produce shape recovery, but bones limit the material recovery so that a dynamic and continuous pressure or clamping force is generated at the fracture end. To achieve the role of fixed fractures.

Since its successful development, Nitinol with unique shape-memory characteristics has been used in oral, neurosurgery, cardiovascular, thoracic surgery, otolaryngology, hepatobiliary, urology, gynecology, etc. The products include orthodontic wires, roots Tube file, spinal orthopedic rod, bone plate (nitinol sheet), intramedullary needle, patella claw, guidewire, guide needle, heart patch, vascular stent, thrombus filter, esophageal stent, respiratory tract stent, biliary stent, urethral stent, rectal stent, twelve Digital stents, external auditory canal stent, birth control ring, etc. Edgetech Industries LLC offers nitinol sheets (nickel titanium alloy sheet, shape memory alloy sheet, superelastic alloy sheet) in a number of formats, allowing for customization of alloy types, thermomechanical conditions, surface finishes, loading plateaus, and tensile strengths.

  Porous titanium products

Porous Titanium

  Porous Titanium products are an alternative material for the human body with structural and functional integration. The surface structure of surgical implants is closely related to the biological behavior after implantation in the body. Compared with dense materials, the introduction of pores significantly reduces the elastic modulus of titanium and its alloys, and the strength and modulus of porous titanium can be adjusted by changing porosity, pore size, and other parameters to adjust its strength and elastic modulus to be fully matched. Its open through-hole structure promotes the adhesion, growth of bone cells, and regeneration and reconstruction of bone tissues, speeds up the healing process, and enables titanium and its alloys to match the elastic modulus of materials and bones while maintaining a certain strength. At the same time, the rough surface geometry of the porous titanium alloy can promote the growth of new bone tissue into the pores, which not only strengthens the biological fixation between the implant and the bone but also allows stress to be transferred along with the implant to the surrounding bone. Edgetech industries can provide porous titanium sheets, rods, and discs with high quality and competitive prices.
