FAQs:
Q: How are the dimensional tolerances of the pin controlled? Can you guarantee a perfect fit with our handle/base?
A: We utilize high-precision centerless grinders or micro-machining centers to manufacture the pins, controlling the diameter tolerance within ±0.005mm (5μm) while ensuring high cylindricity and roundness. Prior to mass production, we can conduct Trial Fits with the client, and fine-tune the tolerance bands based on the material of the client's base (e.g., plastic, metal) to achieve an ideal "push-to-lock" fit state, eliminating the need for secondary machining by the client.
Q: In which medical scenarios is this pin-tailed needle mainly used?
A: It is primarily used in minimally invasive interventional devices requiring extremely high operational precision and repeatable positioning accuracy. Typical scenarios include: firing and retraction mechanisms of biopsy needles, fixation of micro-incision blade tips in ophthalmic or microsurgery, proximal anchor points for neurointervention guidewires, and core moving components in automated cell sampling or micro-pipetting devices.
Q: What is the connection strength between the pin and the needle tube? Is there a risk of loosening or detachment during operation?
A: The pin and needle tube utilize an integral forming process (e.g., precision turning) or high-strength laser welding/brazing. The connection point undergoes stress relief treatment and incorporates a structural interlocking design (e.g., a slotted engagement at the tail of the needle tube encasing the pin), giving it tensile and shear strength comparable to the needle body itself. Within the scope of normal medical operations, there is absolutely no risk of loosening or detachment, meeting the stringent requirements for long-term reliability in medical devices.
Q: If our instrument structure is unique, can we customize the shape, length of the pin, or the needle tip angle?
A: Yes, we specialize in non-standard customization. The pin can be a cylindrical pin, tapered pin, or custom-profile pin, and can even feature flats, retaining grooves, or threads. Additionally, the needle tip angle (e.g., 15°, 30°, 45°), total tube length, and surface coatings (e.g., hydrophilic coating) can be developed and prototyped one-on-one based on your engineering drawings or samples, with functional verification prototypes available in as little as one week.
