Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, in particular to a safe tumor sampling device. Background Art

[0002] Tumors are new growths formed by the proliferation of local tissue cells. The acidity of tumors is slightly stronger than that of healthy body tissues. Tumors can form an "acid wall" to protect themselves from attacks by the immune system. Current medical technology is relatively mature for the diagnosis of tumors, and the treatment and prevention techniques for early tumors are also becoming increasingly perfect. With the continuous development of medical technology, the work of tumor placement will also become increasingly perfect.

[0003] Considering that in the process of tumor diagnosis, the tumor needs to be judged and treated, and then a corresponding diagnosis certificate needs to be issued. At this time, the tumor samples need to be tested for auxiliary diagnosis. At this time, a tumor sampling device is needed for auxiliary sampling. Therefore, some tumor sampling devices with special structures and functions can be used.

[0004] Generally, in actual use, traditional tumor sampling devices need to sample the tumor site, and the principle of traditional sampling tweezers is to use cutting and clamping to sample, which can easily cause internal tissue bleeding. At the same time, if a sampling needle is used for sampling, the tip of the sampling needle is easily separated from the tissue at the tip of the needle during the process of being pulled out of the body after the sampling is completed, and multiple sampling operations are required, resulting in a low success rate of sampling. At the same time, during and after the sampling process, the site where the sampling needle is inserted needs to be disinfected at any time, and the traditional disinfection method cannot be continued, that is, the disinfection cotton needs to be clamped and continuously dipped in disinfectant alcohol for disinfection. Continuously clamping the disinfection cotton will cause hand fatigue, and the method of continuously dipping in disinfectant alcohol will cause the vessel containing the alcohol to be contaminated, which is very inconvenient.
