Description

A disposable endometrial multi-point suction sampler device

technical field

The utility model belongs to the technical field of medical equipment, in particular to a disposable endometrium multi-point suction sampler device.

Background technique

The endometrium is divided into three layers: dense layer, spongy layer and basal layer. Two-thirds of the endometrial surface is dense layer and spongy layer (collectively referred to as functional layer), which are affected by ovarian sex hormones and fall off due to periodic changes. The basal layer is close to the uterine muscle. The 1/3 endometrium of the layer is not affected by ovarian sex hormones and does not undergo periodic changes. Due to the rapid development of my country's economy, changes in lifestyle and diet, and the widespread application of hormone therapy, the incidence of endometritis and endometrial cancer has increased significantly. Sampling for the diagnosis of cancer is mainly to obtain endometrial specimens through a curette. This method is a non-repeatable and traumatic diagnosis method, which will bring great pain to the patient.

The endometrial samplers that have appeared in recent years are mainly realized by the following two methods, one is to collect mucosal cells by balloon or brush, and the other is to use negative pressure suction to collect liquid tissue. During the sampling process of the sampler, the medical staff judge the depth of penetration into the uterus based on their own experience. If the judgment is not accurate, the uterus will be easily injured, the patient will have obvious pain, and serious complications such as perforation and infection may occur. And there is the phenomenon that incomplete sampling leads to inaccurate test results.
