Description

Oral cavity inner wall mucous membrane extraction element for department of stomatology Technical Field The invention relates to the technical field of oral cavity inner wall mucous membrane extraction devices, in particular to an oral cavity inner wall mucous membrane extraction device for stomatology. Background The utility model provides an oral cavity inner wall mucosa extraction element for department of stomatology, is a special medical instrument that designs for department of stomatology field, mainly used draws the sample from patient's oral cavity inner wall mucosa. These samples are typically used for further laboratory analysis, such as pathology, cytological analysis or detection of pathogenic microorganisms. The device typically consists of a convenient sampling tool (e.g., a small aspirator or dedicated sampler) and a support system for protecting the patient's mouth. The extraction process is typically performed by gently touching the mucosal layer of the inner wall of the mouth, ensuring that the sample is effectively obtained without causing discomfort. The design of such an extraction device aims at improving the accuracy and efficiency of sampling and reducing the pain and discomfort of the patient. Compared with the traditional manual sampling method, the oral cavity inner wall mucous membrane extraction device is generally more accurate, can rapidly and accurately acquire a required sample, and avoids errors or discomfort possibly caused by manual operation. The use of the device can greatly improve the efficiency of the dentist in performing clinical examinations or studies, especially when multiple samples are required or large-scale screening is performed. However, prior art extraction procedures often rely on swabs to sample the oral mucosa. Although the cotton swab is easy to handle, problems may occur in its use. For example, cotton wool on a cotton swab can sometimes remain on the inner walls of a patient's mouth, affecting the purity of the sample, and possibly causing discomfort or infection. In addition, in the prior art, rapid detection of the oral mucosa sample after extraction is not realized, and a doctor cannot obtain a detection result immediately after sampling, so that a patient may need to wait for a long time to obtain accurate diagnosis. The utility model provides an oral mucosa sampling equipment that pathology detection used, belong to oral mucosa sampling equipment technical field, including sampling cotton swab, outside sleeve pipe, sampling gun structure, reciprocal sampling device, oral cavity adherence device and oral cavity open strutting arrangement, the strutting arrangement is opened in the oral cavity and is linked to each other with sampling gun structure, reciprocal sampling device links to each other with sampling gun structure, oral cavity adherence device links to each other with reciprocal sampling device, outside sleeve pipe fixed mounting is on sampling gun structure, sampling cotton swab block is installed on oral cavity adherence device. Above-mentioned patent document is in order to assist the inspector, opens patient's oral cavity, reduces the risk that the inspector was stung by the patient, provides an oral mucosa sampling equipment that pathology detected usefulness, when scraping to the oral mucosa is reciprocal to be got and draw the oral cavity sample, still plays the effect of lasting support, expansion to the lip muscle that closes and tooth, and the mouth opens when guaranteeing the oral mucosa sample, makes the patient effectively draw the sample on the oral mucosa. In the above-mentioned patent document, although the device can perform the extraction operation on the oral mucosa of the patient during the use, in the actual use process, the cotton swab in the device may cause the cotton wool to remain in the oral cavity of the patient during the extraction, thereby causing discomfort to the patient. Disclosure of Invention The invention mainly aims to provide an oral cavity inner wall mucous membrane extraction device for stomatology, which can effectively solve the problems in the background technology. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: The utility model provides an oral cavity inner wall mucosa extraction element for department of stomatology, includes hollow section of thick bamboo, hollow section of thick bamboo internal surface upper portion threaded connection has the mobile jib, mobile jib surface upper portion fixed mounting has the adjusting part that is used for adjusting arbitrary angle, mobile jib upper end mid-mounting has sampling assembly, the joint subassembly is installed to hollow section of thick bamboo lower extreme screw thread. Preferably, the limit groove I that runs through to its right side that main pole surface upside left part was seted up, circular groove I has been seted up at main pole upper end middle part, circular groove I internal s
