FAQ:

Q1: What does "dual-needle" of this meniscus biopsy needle specifically refer to? How is it different from ordinary puncture needles?

A1: "Dual-needle" refers to the combined design of "puncture needle (with scale) + detachable sampling trocar": The puncture needle is responsible for accurately puncturing to the meniscus area (scale assists in depth control), and the trocar is responsible for cutting/obtaining tissue samples. Ordinary puncture needles are mostly "single needle + fixed edge", which cannot flexibly replace the trocar, and depth control relies on experience, easily leading to sampling failure or tissue damage.

Q2: What is the scale precision of the needle body? Can it meet the depth requirements of meniscus surgery?

A2: The scale precision is 1mm​ (adjust according to actual product parameters). The puncture depth required in meniscus surgery is usually 10-30mm​ (varies with injury location/surgical procedure). The scale intuitively displays the insertion depth, helping doctors operate precisely and avoid damaging important structures such as joint cartilage and blood vessels.

Q3: Can the trocar be purchased separately? What should be noted when replacing it?

A3: The trocar supports separate purchase. When replacing, ensure: ① The interface specifications​ of the trocar and puncture needle fully match (e.g., thread/catch type); ② The new trocar is an original/reasonable compatible product​ to avoid loosening or sampling failure due to interface mismatch; ③ Clean and disinfect the puncture needle interface before replacement to prevent pollution.

Q4: Is this product suitable for all meniscus surgeries? Such as meniscus suture, partial resection, etc.?

A4: It is mainly suitable for meniscus biopsy (diagnosing lesions)​ and minimally invasive partial resection (removing damaged tissue). For meniscus suture, it needs to be matched with special suture instruments (this product can be used as a "puncture guide needle" to assist positioning, but the core suture instrument is the suture anchor/suture system). Consult the manufacturer or clinical experts for specific surgical adaptation.

Q5: Will the stainless steel material cause tissue adhesion or inflammatory response?

A5: Medical-grade stainless steel (e.g., 304/316L) has excellent biocompatibility, with a smooth surface and high chemical stability. When in long-term contact with human tissue, it rarely causes adhesion, allergy or inflammation. During clinical use, the doctor's standardized aseptic operation + postoperative care​ can further reduce related risks.
