Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a gynecological tumor sample tissue sampling device which comprises a protective cylinder, an injection cylinder, an injection needle and a sliding rod, and a closing cover capable of being opened and closed is arranged at one end of the protective cylinder; the syringe is arranged in the protective cylinder, the injection needle is connected to the end, close to the sealing cover, of the syringe, and the sliding rod is arranged in the syringe and abuts against the interior of the syringe; a first movable handle which simultaneously penetrates through the side wall of the injection cylinder and the side wall of the protective cylinder and is movable is connected to the sliding rod, and a second movable handle which penetrates through the side wall of the protective cylinder and is movable is connected to the side wall of the injection cylinder; and a limiting device and a fixed handle are arranged on the side wall of the protective cylinder. According to the device, the gun holding posture is kept in the sampling process, the hand easily exerts force, the device is easily held, the injection needle after sampling is located in the sealing cover, the sealing performance is good, and pollution is not likely to be caused.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a tissue sampling device for gynecological tumor samples. Background technique [0002] Common gynecological tumors include vulvar tumors, vaginal tumors, uterine tumors, ovarian tumors, and fallopian tube tumors. Tumors of the uterus and ovary are more common, while tumors of the vulva and fallopian tubes are rare. Sampling and testing tumors is an important measure to determine the nature of tumors and treat tumor diseases. Because some tumors may be malignant, in order to prevent the metastasis of these malignant tumor cells, the method of sampling by syringe puncture is usually used. The structure of the syringe includes a puncture needle, a syringe and a push rod. The handle of the syringe is short and difficult to hold, and there is no protective device on the outside of the needle, so the taken out sample is exposed to the air, which may cause infec...
