Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a gynecological tumor sampling device.
Background
Gynaecology is a diagnosis and treatment subject of medical institutions, and is a branch of the major of gynaecology and obstetrics, and is a major department for diagnosing and treating female gynecopathy. Among the common gynecological tumors, there are vulvar tumor, vaginal tumor, uterine tumor, ovarian tumor and fallopian tube tumor. The tumors of uterus and ovary are common, and the tumors of vulva and fallopian tube are rare. When the common symptoms of gynecological tumor appear, the patient should go to the hospital for examination in time and make a judgment through pelvic examination and various auxiliary examinations. The tumor is a new organism formed by local histiocyte proliferation of an organism under the action of various tumorigenic factors, because the new organism mostly presents an occupied block-shaped bulge, also called a neoplasm, before a tumor patient is treated, the tumor needs to be sampled and analyzed, and medicines are administered according to symptoms, two current popular modes are adopted, one mode is directly sampling through a scalpel, and the other mode is sampling through an injector.
Some technical schemes related to tumor sampling devices also appear in the prior art, for example, a chinese patent with patent number 2017203933743, the invention provides a gynecological tumor sampling device, which comprises a rotating shaft and a sampling bottle, wherein the outer wall of the right end of a transparent shell is provided with a slot, and a metal block is adhered in the slot; the guide sleeve transversely penetrates through the outer wall of the transparent shell, and the left end face of the guide sleeve penetrates through the inner cavity of the transparent shell; the compression column penetrates through the inner cavity of the guide sleeve; a latex telescopic sleeve is adhered to the left end face of the transparent shell; the planker is installed on transparent shell's inner wall, and the sampling bottle runs through to be installed in the mounting hole of planker, and the rotatory back of sample scissors, the knife tip can aim at the bottleneck of sampling bottle, the sample scissors after the sample of being convenient for, place the sample of taking a sample in the inner chamber of sampling bottle, accomplish whole sampling process, make sample work go on and accomplish in transparent shell's cavity, when making whole device structure more reasonable, still have fine isolation, make the sampling process more sanitary, the sample quality is better.
But the tumour sampling device in the above-mentioned technique takes place the insufficient condition of cutting easily when using the sample scissors sample, and the sample accuracy is relatively poor, and whole sample work quality is low, and the sample drops easily at the cutting completion and put into the in-process of sampling bottle inner chamber simultaneously, greatly reduced the stability of tumour sampling device when using.
In view of the above, the invention provides a gynecological tumor sampling device, wherein the cutting mechanism is arranged in the tumor sampling device, so that the tumor can be accurately and fully cut by the cutter, and meanwhile, the cut tumor sample is effectively stored, thereby greatly improving the stability and convenience of the gynecological tumor sampling device in working.
Disclosure of Invention
In order to make up for the defects of the prior art, the invention provides the gynecological tumor sampling device, the cutting mechanism is arranged in the tumor sampling device, so that the tumor can be accurately and fully cut by the cutter, the cut tumor sample can be effectively stored, and the stability and convenience of the gynecological tumor sampling device in working are greatly improved.
