Pathological sampling device for cervix uteri

Abstract

The invention discloses a pathological sampling device for the cervix uteri, and mainly relates to the field of pathological sampling devices. The pathological sampling device comprises a main rod, anauxiliary rod, a first connecting rod, a second connecting rod, a third connecting rod and a brush rod, wherein the first connecting rod and the second connecting rod are arranged between the main rod and the brush rod in a manner of being parallel to each other up and down, the bottom end of the third connecting rod is hinged to the top end of the auxiliary rod, the main rod and the auxiliary rod are arranged in parallel, the auxiliary rod is in sliding connection with the main rod along the length direction of the main rod, a threaded rod is arranged on the bottom of the main rod, an adjusting sleeve in threaded connection with the threaded rod is arranged on the threaded rod, a connector is arranged at the bottom end of the auxiliary rod, the connector and the adjusting sleeve are rotatably connected in a concentric manner, bristles are arranged at the upper part of the brush rod, and the first connecting rod is provided with a plate brush or a scraper blade. The pathological sampling device has the beneficial effects that the view exposure of the pathological area especially the squamocolumnar junction in the cervical canal is good, and the adaptation of the bristles / plate with the surface of the cervix uteri of a patient is good.

Description

technical field [0001] The invention relates to the field of pathological sampling devices, in particular to a cervical pathological sampling device. Background technique [0002] In modern clinical medicine, more and more cytopathology is used to assist in the diagnosis of diseases. Therefore, pathological specimen sampling is a common clinical operation. The collection requirements and operation methods of pathological specimens in each department are quite different. In the field of gynecology, cervical cytology has always been the right-hand man for cervical cancer screening. It refers to taking a small amount of cell samples from the cervix, processing them, and placing them under a microscope to observe the small early changes of cervical cells. The proposal of this technology can be sniped before the cancer has occurred, thus greatly reducing the mortality rate of cervical cancer. Although some countries now propose HPV as a primary screening method for cervical ca...

Problems solved by technology

Due to the characteristics of the operating part, the doctor can only observe inward through the opening of the duckbill

However, the operating rods (extended rods) of the existing scrapers or cervical brushes are all set in the center, and because the depth is deep and narrow, it is also very difficult to let the central field of vision by tilting and staggering the scraper / brush, which makes the doctor's field of vision Severely blocked, unable to fully expose the squamous-columnar junction area in the cervical canal, which directly affects the doctor's judgment and implementation of the pathological sampling area, as well as the judgment and handling of the rubbing / scraping force, frequency, and range
