Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a sampling device for diagnosing vaginal tumors. Background Art
[0002] Vaginal tumors can be divided into benign tumors and malignant tumors. Benign vaginal tumors include fibroids, leiomyomas, hemangiomas, lipomas, neuromas, myxomas and papillomas, etc., which are equivalent to their histological origins. Benign vaginal tumors generally do not produce obvious symptoms. Vaginal malignant tumors refer to lesions of malignant tumors that occur in the vaginal wall tissue. There are primary and secondary ones. Secondary ones are mostly metastases from cervical cancer, vulvar cancer, endometrial cancer, rectal cancer, etc.; primary vaginal malignant tumors are rare, accounting for about 2% of gynecological malignant tumors. When women suffer from vaginal tumors, they need to judge the nature of the tumor. To determine whether it is benign or malignant, a sampling device is needed to sample the diseased part of the woman. The following problems exist in the existing technology:
