Description

Oral mucosa sampling device Technical Field The invention relates to the field of oral cavity sampling, in particular to an oral mucosa sampling device. Background Oral mucosa sampling is a common operation means in clinical diagnosis, disease screening and medical research, and can be used for multiple purposes such as gene detection, pathogenic microorganism detection, early tumor screening and the like by acquiring oral mucosa epithelial cells. At present, oral mucosa sampling tools widely used clinically mainly comprise sterile cotton swabs, cell brushes, curettes and the like. However, the oral mucosa sampling device in the prior art has the following disadvantages: First, the operation is inconvenient, relying on assistance. Traditional sampling tool function singleness only possesses the sample function. In practice, a medical professional needs a hand-held sampling tool and the other hand uses an opener or tongue depressor to prop open the patient's mouth to obtain an operational view and space. The double operation or single double operation mode is complex in operation, and when the patient's coordination degree is poor (such as children and the elderly), the sampling difficulty is greatly increased, and even sampling failure or instrument damage can be caused by sudden closing of the patient. Second, there is blindness in the sampling process. Most of the existing sampling tools are "blind taking", operators cannot observe the conditions in the oral cavity in real time, and are difficult to accurately align to lesion parts or target areas, especially for lesions with hidden positions and smaller ranges, sampling accuracy is difficult to guarantee. It is also not possible to confirm successful cell harvesting after sampling, and repeated sampling is often required. Thirdly, the sample is easy to be polluted and the subsequent treatment is complicated. After the traditional cotton swab or brush is used for sampling, the sample is required to be transferred to a preservation tube or a culture medium, external pollution is easily introduced in the transfer process, and the sample is exposed in the air for a long time, so that cell degradation is possibly caused, and the accuracy of a detection result is affected. In addition, the sample needs to be marked manually, and information confusion is easy to occur. Fourth, the patient experience is poor. The hard curet or brush directly scrapes mucous membrane, easily causes pain, bleeding and tension, and causes low patient coordination. The prolonged opening of the stoma is also uncomfortable for the patient, especially in case of multiple sampling or prolonged operation. In view of the above problems, some improvements attempt to integrate illumination or simple observation structures on sampling tools, but still fail to fundamentally solve the problems of low operational integration, single sampling mode, inconvenient sample preservation, and the like. Therefore, it is necessary to develop an integrated, visual, convenient-to-operate and patient-friendly oral mucosa sampling device to improve sampling efficiency and quality and improve clinical experience. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to provide an oral mucosa sampling device. The technical scheme of the invention is as follows, and the oral mucosa sampling device is characterized by comprising: The handle comprises a handle and a sampling rod arranged at the front side of the handle, a flushing pipe and a return pipe are arranged on the handle, the flushing pipe and the return pipe extend to the front end of the sampling rod respectively, a first pump body is arranged on the flushing pipe, and a second pump body is arranged on the return pipe; The flushing bottle and the sample bottle are respectively detachably arranged on the handle, the flushing pipe is inserted into the flushing bottle, and the return pipe is inserted into the sample bottle; The sampling head is provided with a flushing cavity and a reflux cavity, the sampling head is detachably arranged at the front end of the sampling rod, the flushing cavity is communicated with the flushing pipe, the reflux cavity is communicated with the reflux pipe, the working face of the sampling head is provided with a flushing port communicated with the flushing cavity and a reflux port communicated with the reflux cavity, the flushing port and the reflux port are arranged on the working face at intervals to form a liquid flow path from the flushing port to the reflux port, and the flow path passes through a contact area of the working face and oral mucosa; The oral cavity expanding piece is arranged on the sampling rod and is provided with an expanding state and a containing state, when the oral cavity expanding piece is in the expanding state, the oral cavity expanding piece is used for expanding an oral cav
