Description
Technical Field
The utility model provides a testicle puncture biopsy needle, belonging to the field of medical instruments.
Background
Testicular biopsy is a clinical technique with dual functions of diagnosis and treatment, which is to take out a small piece of living testicular tissue by a simple surgical method, and to perform histological observation of pathological sections to understand the testicular spermatogenic status, to diagnose testicular diseases and to evaluate prognosis. At present, hormone examination methods and biochemical examination methods are also used for examining the sperm production function of the testis, and compared with testis biopsy, the hormone examination methods and the biochemical examination methods cannot accurately reflect the sperm production function of the testis. Because testicular biopsy directly examines the seminiferous tubules of the testis, while endocrine and biochemical examinations indirectly understand spermatogenic function. At present, the testicle biopsy is the gold standard for diagnosing the spermatogenic function of the testicle, so the examination is required for patients without spermatozoon. However, many of the existing examinations are performed manually, and after all, when the examinations are performed manually, it cannot be guaranteed that no errors occur in the operation process, for example, if one hand is shaken, a certain negative effect is caused on the postoperative recovery of a patient, so that a device capable of completing testicular biopsy by using a fixed machine as much as possible is needed.
