Huizhou Pengchengrui Technology Co., Ltd.

Nickel titanium (nickel titanium memory alloy) core characteristics: super elasticity, shape memory effect, biocompatibility, corrosion resistance, fatigue resistance, divided into two directions: pet medical (mainstream) and pet consumer products.

1、 Pet veterinary medicine (primary application)

1. Self expanding stent for cavity (minimally invasive intervention)

1) Canine tracheal collapse stent

Small dogs such as Yorkshire and Pomeranian have a high incidence of tracheal collapse. A nickel titanium self expanding stent is woven, compressed into a sheath at low temperatures, and released into the body to automatically open the trachea; Flexibility close to tracheal cartilage, minimally invasive implantation under endoscopy to improve breathing difficulties, is an important treatment option for end-stage tracheal collapse, which can be retracted and adjusted in position.

2) Male cat urethral stricture/recurrent urinary obstruction urethral stent

Targeting stubborn urethral stricture and recurrent urinary obstruction in male cats. Temperature controlled nickel titanium stent, softened and thinned under ice water conditions, inserted into the urethra through a guide wire; The temperature/warm water environment automatically expands and supports the urethra, preserving the original urethral structure and avoiding urethral ostomy surgery; When it needs to be removed, the ice water cooled bracket can be softened to solve the problem of urinary obstruction caused by crystallization and scar stenosis.

2. Minimally invasive interventional instruments

-Animal endoscope: Insert a nickel titanium spring skeleton woven inside the catheter to achieve large angle bending and maintain push stiffness, used for minimally invasive surgery of gastrointestinal and respiratory tract examination in cats and dogs.

-Interventional consumables: stone retrieval basket, grabber, guide wire, thread guide, used for minimally invasive stone retrieval of bladder stones, biliary tract, and urinary tract, resistant to repeated bending and not easily broken.

3. Orthopedic surgery

-Elastic intramedullary nail (ESIN): For long bone fractures in small cats and dogs, nickel titanium elastic nails are minimally invasive implanted into the bone marrow cavity for elastic fixation, reducing soft tissue damage and protecting the growth plate of young pets. It is suitable for small dogs and cats with limb fractures.

-Memory saddle stitch nail and fixed splint: using shape memory, automatically clamping the fractured end after heating, used for superficial fracture fixation; Compared to stainless steel, the elastic matching of animal bones reduces the risk of stress shielding.

>Attention: The mainstream in orthopedics is still titanium alloy and stainless steel. Nickel titanium is mostly used for elastic fixation, and it is less commonly used alone for large weight-bearing shaft fractures.

2、 Pet consumer goods

1. Pet toys

Super elastic nickel titanium wire cat teasing stick: used as the inner core of the cat teasing stick. Ordinary steel wire will be permanently broken by repeated bending; Nickel titanium can withstand large bending, automatically rebound after cat bites and entanglements, with minimal fatigue attenuation after millions of bending cycles. It simulates the fluttering and shaking trajectory of small insects, greatly improving durability. There are also intelligent electric toys that use nickel titanium memory wires to contract and reset when powered off, acting as "artificial muscles" to drive the toy to swing.

2. Smart pet supplies

Explosion proof charging traction device: Nickel titanium memory wire is used as the driving element to detect the instantaneous electrical contraction of the pet's charging, triggering the locking mechanism; Small in size and fast in response, used for patented solutions of automatic telescopic traction ropes.

3、 Advantages and disadvantages of materials

✅  Advantages

1. Super elasticity: deformation can reach 8% with complete rebound, while ordinary steel only has 0.5%;

2. Shape memory: Low temperature compressible shaping, restoring the preset shape at body temperature, suitable for minimally invasive implantation;

3. Corrosion resistance and good biocompatibility in the body;

4. Anti fatigue, not easily broken after repeated bending.

❌  shortcoming

1. The cost is much higher than stainless steel and ordinary titanium alloys;

2. Nickel precipitation risk: Medical grade strict control, long-term implantation of inferior materials poses hidden dangers;

3. Temperature sensitivity, surgical operations require temperature control;

4. There is a risk of clinical complications such as tissue proliferation, crystal wall hanging, and displacement in the stent, and veterinarians need to strictly control the indications.

4、 Industry Status

Nickel titanium stents in pet medical care belong to specialized advanced minimally invasive techniques, which are gradually becoming popular in China and are mostly used for difficult cases with poor traditional surgical outcomes; The consumer end is mainly used for high-end toys such as cat teasers, and nickel titanium alloy is rarely used in ordinary and affordable pet products.

Huizhou Pengchengrui Technology Co., Ltd. specializes in customized nickel titanium alloy solutions for the pet industry. Relying on the advantages of nickel titanium super elasticity, shape memory, corrosion resistance, and biocompatibility, we can customize pet medical stents, orthopedic components, pet toy elastic components, etc. We offer one-stop processing from wire materials, pipes to finished devices, and can adjust phase transition temperature and mechanical parameters as needed, empowering pet medical and pet supplies enterprises to provide stable and reliable material and device customization services.
