Biopsy needle

Bone and soft tissue tumors are one of the major diseases that threaten human life. Moreover, in recent years, the probability of people suffering from tumor diseases has gradually increased. Although there are few effective means to treat malignant tumors, diagnosing tumors and differentiating between benign and malignant tumors is crucial. The commonly used method for diagnosing tumors is puncture biopsy, and the biopsy needle is the medical device used for puncture surgery.

Because limb-sparing treatment of malignant tumors has become a major trend, this requires stricter requirements on the route and method of sampling during biopsy. Improper biopsy often causes the tumor to contaminate important local structures such as blood vessels and nerve bundles during sampling, making it impossible to completely remove the tumor and leading to failure of limb-salvage treatment. Therefore, before the puncture biopsy, one should have a full understanding of the nature, stage and treatment of the tumor, make adequate preoperative plans, and ensure that the needle track for sampling is located on the surgical incision so that it can be completely removed during surgery. Therefore, a large number of literatures emphasize that puncture biopsy should be performed by experienced specialists, and it is best for the surgeon to perform the biopsy personally to improve the accuracy of puncture biopsy and reduce complications.

Important principles

Therefore, we recommend the following important principles before performing a biopsy:

1. Before biopsy, you should attach great importance to it and make careful plans just like making a surgical plan. Because this is the beginning of tumor treatment and is a crucial first step, an incorrect biopsy can have disastrous consequences for the patient.

2. The aseptic operation principle should be strictly followed, and skin preparation, hemostasis and suture should be performed like conventional surgery.

3. Ensure that the biopsy does not affect the formulation of subsequent surgical plans, and the contaminated area of ​​the biopsy should be able to be completely removed.

4. Ensure that there are enough representative tissue specimens for the pathologist to diagnose. If the pathologist cannot make a clear diagnosis, detailed clinical and imaging examination data should be provided in a timely manner.

5. If the doctor or hospital does not have the conditions to diagnose and treat tumors, the tumor patient should be transferred to a doctor or hospital that has the conditions to diagnose and treat tumors for formal treatment before biopsy.
