Titanium but not just titanium
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)
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, and 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 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.
