Features include:
• Switzerland TONRNOS CNC automatic cutting lathe;
• innovative oxidation process, which improves the surface hardness and wear resistance of screws;
• imported titanium alloy, which achieves the best hardness and optimal flexibility;
Cross head screwdriver: SW0.5*2.8*75mm straight quick coupling handle is the matching tool.
Plates with chamfered edges and a wide profile that are ultra low profile provide almost little palpability. accessible in a far more flexible length.
Benefits of screws made of titanium alloy
1. Great power. Although titanium has a density of 4.51g/cm³—higher than aluminum and lower than steel, copper, and nickel—it is far stronger than these metals. Titanium alloy screws are robust and light.
2. Good resistance to corrosion: Titanium and titanium alloys are highly stable in a wide range of media, making them suitable for use in harsh environments.
3. Strong tolerance to low temperatures and heat.Titanium alloy screws are able to function at temperatures as high as 600 °C and as low as 250 °C while still keeping their shape.
4. Non-toxic and non-magnetic.High magnetic fields will not cause titanium to become magnetized because it is a nonmagnetic metal.Not only is it non-toxic, but it also works well with the human body.
5. Excellent damping resistance. Titanium exhibits the longest vibration attenuation period following mechanical and electric vibrations when compared to steel and copper.This performance can be applied to sophisticated audio loudspeakers as vibration films, medical ultrasonic grinder vibration components, and tuning forks.
Low insertion torque and fast screw beginning are features of the thread design. A large assortment of plates and mesh, such as burr hole coverings for shunts and mastoid and temporal meshes.
Is it preferable to have a tighter screw?
In orthopedic surgery, screws are frequently used to stabilize the bone to the internal or external fixation frame, compress the fracture site, and fasten the plate to the bone.The torque used by the surgeon determines how much pressure is needed to get the screw into the bone.
The screw's gripping force on the bone decreases and it is dragged out a short distance as the torque force grows and the screw reaches its maximum torque force (Tmax).The tension needed to twist the screw out of the bone is called pull-out force (POS). It is frequently employed as a parameter to gauge the screw's holding force.It is currently unknown how the maximum torque and the pull-out force relate to one another.
Orthopedic surgeons typically use 86%Tmax while inserting screws in clinical settings.However, Cleek et al. discovered that the maximum POS could be achieved by inserting 70%Tmax screws into sheep's tibia. This suggests that using excessive torsion force may be employed clinically, which would decrease fixation stability.
Tankard et al.'s recent investigation on the humerus in human cadavers discovered that the maximum POS was reached at 50%Tmax.The inconsistent use of the specimens and the various measurement standards could be the primary causes of the discrepancies in the results shown above.
Thus, using screws placed into the tibia of human cadavers, Kyle M. Rose et al. from the United States investigated the association between various Tmax and POS and also examined the relationship between Tmax and BMD and cortical bone thickness.Techniques in Orthopaedics released the paper lately.According to the results, screw torque can be used to achieve the maximum and comparable points of sale at 70% and 90%Tmax. Notably, the POS attained at 90%Tmax screw torque is substantially higher than that at 100%Tmax. The tibia groups did not differ in BMD or cortical thickness, and there was no relationship seen between Tmax and the aforementioned parameters. As a result, in actual clinical settings, the surgeon should torque the screw slightly less than Tmax rather than using the maximum torsion force. Overtightening the screw still has some benefits, even if 70% and 90%Tmax can accomplish comparable POS; nevertheless, the torque shouldn't go above 90% to maintain the fixation effect.
