Abstract
The utility model provides a sampling device used for carrying out cytological examination on tissues of pancreatic and bile ducts. The sampling device is composed of a sheath pipe and a sampling inner core. A reticular air bag is arranged at the front segment of the sampling inner core, the head end of the sampling inner core presents the shape of a smooth cone, and the tail end of the sampling inner core is an operation handle; a layer of reticular structure is adhered on the outer surface of the reticular air bag, presenting the transverse and longitudinal interlacing shape. The sampling device adopts simple structure and is convenient for use. The operating method of the sampling device is the same as that of the ordinary pancreatic and bile ducts. After the reticular air bag is expanded, lattices on the surface of the air bag obviously exert greater cutting action on the tissues than a sample which is obtained simply by contact friction, thereby greatly increasing the success rateof pathological material obtaining, leading rich cell content of the collected sample, obtaining tissue cells at the deep part under a mucous membrane, obviously improving the sensitivity, and reducing the number of times of repeated operation as well as examination.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of netted air bag sampler, is specifically related to a kind of netted air bag sampler that the pancreatic duct histocytology is checked (biopsy) that is used for.
Background technology
Pancreatic duct is narrow to be clinical common disease, and sickness rate is very high, and its cause of disease mainly comprises inflammation, calculus, fibrosis, tumor or the like.At the different causes of disease, there is very big difference in the method for Clinical Processing, as is benign stricture, generally only needs dilation therapy; As be malignant stricture, then take operative treatment as far as possible, the auxiliary in case of necessity chemicotherapy that carries out.Therefore, understanding narrow pathology character is the key of clinical treatment.Originally, the clinician mainly diagnoses according to the iconography feature of lesions position, as inspections such as CT, MRCP and ERCP, there is certain blindness in the result, causes mistaken diagnosis easily, has developed cytology brush inspection under the scope afterwards gradually, though improved the accuracy of diagnosis to a great extent, but still have some defectives, mainly when the brush inspection fine, soft fur be difficult to and tube wall between form effective length tension relation, thereby influenced the effect of cytology brush inspection.For serious narrow tube chamber position, cytology brush can be brought into play stronger sample of tissue effect, but for the less tube chamber of stenosis, the positive rate of cytology brush is then very limited.External report, cytology brush can reach about 60% the positive rate of diagnosis pancreatic duct cancerous stricture, and domestic report only is about 30%.
The utility model content
The purpose of this utility model is to provide a kind of easy to use, the success rate of drawing materials height, thereby makes the higher netted air bag sampler of pathological diagnosis sensitivity, relates in particular to a kind of netted air bag sampler that the pancreatic duct histocytology is checked (biopsy) that is used for.
