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.
