FAQ

What are the materials used to manufacture minimally invasive orthopedic surgical instruments?

The materials used to manufacture minimally invasive orthopedic surgical instruments mainly include the following:

Stainless steel: This is one of the most common materials with good mechanical properties and corrosion resistance. For example, tools used to ream intervertebral discs are usually made of stainless steel.

Titanium alloy: It is widely used because of its light weight, high strength and good biocompatibility. Some foreign products have applied titanium alloys to reusable instruments. In addition, titanium alloys are also commonly used in orthopedic implants and surgical instruments.

Polymer materials: Such as polyester fiber, glass fiber, etc., these materials are also used in certain specific cases.

Nitinol alloy: This material is also used in some minimally invasive surgical instruments that require high-precision processing.

Aluminum alloy: Some specific surgical instruments may use aluminum alloy materials.

Tungsten, platinum: These materials are mainly used for minimally invasive surgical instruments in electrosurgical equipment, such as electrodes.

PEEK (polyetheretherketone): This is a high-performance polymer with good mechanical properties and biocompatibility, suitable for innovative products such as absorbable bone repair materials and 3D printed personalized prostheses.

Ultra-high molecular weight polyethylene: This material is often used in high-bionic gaskets for knee prostheses.

Cobalt-chromium-molybdenum alloy: used for metal parts of knee prostheses.

The selection of these materials depends on the specific application environment and requirements, as well as the comprehensive consideration of factors such as the mechanical properties, biocompatibility and processing difficulty of the instrument.

What are the specific applications and performance of stainless steel in minimally invasive orthopedic surgical instruments?

In minimally invasive orthopedic surgical instruments, the application and performance of stainless steel have significant advantages. First of all, stainless steel materials are widely used in the field of medical devices due to their excellent corrosion resistance and mechanical strength. , Because it is tough and very corrosion-resistant, it is often used to manufacture instruments that need to be used in the human body for a long time.

Specifically for minimally invasive orthopedic surgical instruments, stainless steel not only meets the special requirements of strength, hardness, rigidity, toughness, wear resistance and corrosion resistance, but also is suitable for the design of complex shapes through its excellent formability. For example, in dual-channel minimally invasive spinal endoscopic surgical instruments, high-quality domestic stainless steel materials are used, and the surface is matte and finely processed to ensure product performance and hand comfort
. In addition, as a new type of stainless steel, 465 alloy has unique properties that enable it to design instruments with smaller sizes and cross-sectional areas, and provides twice the impact toughness of other commonly used medical precipitation-hardened stainless steels (such as 455 and 17-4 alloys) under the same material strength conditions.

In practical applications, the performance of stainless steel in minimally invasive surgery has also been verified. For example, tools such as orthopedic milling cutters are made of stainless steel, which has high cutting efficiency and high corrosion resistance, and can perform precise cutting and milling operations with minimal incisions. In addition, some high-strength stainless steels such as UNSS17400 (commonly known as 17-4PH or 630 type) are often used to make screws and implants that require ultra-high mechanical strength.

What are the latest advances in the reuse technology of titanium alloys in minimally invasive orthopedic surgical instruments?

In recent years, there have been significant advances in the reuse technology of titanium alloys in minimally invasive orthopedic surgical instruments. Here are a few key points:

Application of 3D printing technology: In September 2021, the National Medical Products Administration (NMPA) officially approved the listing application of Zhongnuo Hengkang's "3D printed titanium alloy intervertebral fusion device", which marked an important breakthrough in the application of 3D printing technology in orthopedic minimally invasive devices. 3D printing technology can customize titanium alloy materials according to the specific needs of patients, thereby improving their biocompatibility and mechanical properties, making them perform better in terms of repeated use and long-term stability.

Research and development of new medical titanium alloy materials: In order to improve and enhance the biocompatibility and mechanical compatibility of medical titanium alloy materials, researchers have conducted in-depth research on alloy design, microstructure and phase change control, and surface state optimization. These improvements help to improve the durability and safety of titanium alloys during repeated use.

Auxiliary applications of nickel-titanium memory alloys: In addition to traditional titanium alloys, nickel-titanium memory alloys have also been widely used in the field of minimally invasive interventions due to their unique shape memory effect, superelasticity, and corrosion resistance. For example, nickel-titanium alloys are used in high-end metal instrument products such as vascular stents, occluders, and vena cava filters. These applications demonstrate their reliability and effectiveness in complex surgical environments.

Improvement of tissue compatibility and corrosion resistance: In specific applications, such as wrist arthroscopy-assisted titanium internal fixators for the treatment of complex distal radius fractures, studies have shown that titanium alloys have good tissue compatibility and corrosion resistance, and will not produce toxic and side effects, ensuring the safety and effectiveness of the instrument after multiple uses.

Application cases and effect evaluation of polymer materials (such as polyester fibers and glass fibers) in minimally invasive orthopedic surgical instruments.
The application cases and effect evaluation of polymer materials in minimally invasive orthopedic surgical instruments can be discussed from multiple aspects. The following is a detailed analysis based on existing data:

Application cases
Glass fiber composites:

Studies have shown that glass-containing composites have good biocompatibility, are easy to handle, and have a short setup time. For example, Niiranen et al. developed self-reinforced polylactic acid/bioactive glass composite rods for fracture fixation and successfully used them in osteotomy of distal femoral bone gaps in rats.
In addition, the study found that direct contact between bone tissue and glass fibers and adjacent polymer matrix significantly improved interfacial bonding strength compared with the polymer control group.
Polyester fiber drapes:

In neurosurgery, long-fiber polyester fiber drapes are used to reduce the occurrence of intraoperative hypothermia and reduce the incidence of surgical site infection (SSI). Studies have shown that the postoperative colony culture positive rate of the group using long-fiber polyester drapes was significantly lower than that of the cotton woven cloth group, and the antibacterial effect was significant.
Effect evaluation
Biocompatibility and repair effect:

Glass-containing composite materials showed the effect of improving bone regeneration in the repair of rabbit femoral condyle and tibial defects, but the composite material still needs to be further optimized to become an ideal bone filling material.
Self-reinforced polylactic acid/bioactive glass composite rods showed good fracture fixation effect in animal experiments, which provided preliminary basis for clinical application.
Antibacterial properties:

Studies on surgical gowns made of long-fiber polyester fiber materials showed that their antibacterial effect was significantly better than that of cotton woven cloth materials, and the postoperative colony culture positive rate of various parts was significantly reduced, indicating that long-fiber polyester fiber materials have advantages in antibacterial properties.
Summary
The application of polymer materials such as glass fiber and polyester fiber in minimally invasive orthopedic surgical instruments has made some progress. Glass fiber composites have shown potential in bone repair and fracture fixation due to their good biocompatibility and excellent interfacial bonding strength; while long-fiber polyester fibers have outstanding performance in reducing intraoperative hypothermia and surgical site infection.
