Description

Gynecological tumor sampling device

Technical Field

The utility model belongs to the technical field of gynecological tumor sampling, and particularly relates to a gynecological tumor sampling device.

Background Art

Gynecological tumor sampling refers to obtaining tissue samples from the female reproductive system for pathological examination through a series of examinations and operations to determine whether there are tumors or other diseases. Clinically, tumor sampling can be achieved through surgical incisions, but due to the large wound, it causes great pain to the patient. For this reason, syringes are currently mostly used for sampling, and the tumor tissue is absorbed by the negative pressure generated during suction. Although this sampling method has the advantage of small wounds, it may not be able to obtain tumor tissue only through negative pressure suction. In addition, when sampling gynecological vaginal tumors, the sampling needle directly passes through the vagina to sample, which will puncture the healthy vaginal wall when searching for tumor tissue. When extracting tumor tissue, other fluids such as tissue fluid are often extracted, and these fluids are mixed with the obtained tumor tissue.

A gynecological tumor sampling device with the publication number of "CN209018806U" comprises a syringe, a sample container, a sampling needle, and a cannula. The piston and piston rod of the syringe are provided with a through hole along the central axis direction. The front end of the syringe is threadedly connected with the sampling needle, the sampling needle is sleeved with a cannula, and the side wall of the syringe is threadedly connected with the sample container; the sampling needle is hollow inside, the front end is closed and sharp, the front end side wall of the sampling needle is provided with a sampling hole, the sampling needle is provided with a bowl-shaped scraper inside, the bowl-shaped scraper is fixedly connected to the front end of the knife rod, and the rear end of the knife rod passes through the piston and the piston rod and is connected to the pull ring; a filter is provided in the middle of the sample container; the cannula is hollow inside, the front end of the cannula is spherical, the rear end of the cannula is fixedly connected to the connecting sleeve through a spring, and the side wall of the rear end of the cannula and the side wall of the connecting sleeve are provided with a plug-in hole, and an "n"-shaped connecting rod is plugged into the plug-in hole. The device can protect healthy tissue, obtain sufficient tumor tissue samples, and isolate tumor tissue from extracted tissue fluid.

The above-mentioned device uses a toggle scraper for scraping, and the overall back and forth toggle method has poor scraping ability, cannot cut and sample the tissue well, and the sampling ability is relatively insufficient. At the same time, during its use, the overall operation range of the toggle lever is small, and it is cumbersome and inconvenient to toggle when it goes deep into the patient's body.

In summary, the utility model mainly has the following beneficial effects:

First, the sampling needle tube is shielded by the outer protective tube, so that the sampling needle tube can be better protected to avoid accidentally stabbing the patient's internal organs. When the device penetrates into the patient's body, the bottom cap and the outer protective tube can be buffered and protected by the buffer spring, so that the device can have a good protective buffering effect and can avoid causing harm to the patient. When sampling is required, the connecting rod can be pulled by pulling the lifting frame, and the connecting rod can pull the bottom cap upward, thereby driving the protective tube to move upward, and the sampling needle tube can be exposed at this time, so that the device can quickly and conveniently flexibly adjust the extension of the sampling needle tube, which is convenient for sampling;

Second, connect the syringe through the connecting hose at the outer end of the sampling hose, and use the syringe to draw tissue fluid for collection. At this time, the tissue fluid is transported to the inside of the collection tank through the sampling tube and the delivery tube. When the tissue fluid needs to be taken out, the sealing cover can be twisted to open the extraction tube for extraction. When further cleaning is required, the sealing cover at the bottom can be opened to quickly clean the inside of the collection tank;

Third, by pulling the lifting frame, the connecting rod is driven to slide on the inner side of the reinforcement sleeve, and then the bottom cap can be quickly pulled by the connecting rod. The bottom cap can be pulled to drive the internal threaded sleeve to move. Since the internal threaded sleeve and the external threaded sleeve are threadedly connected to each other, the sampling needle tube can be driven to rotate through the thread. The rotation of the sampling needle tube can drive the sampling scraper to rotate. At this time, the lifting frame is released again, and the telescopic spring is reset to drive the bottom cap to move downward. This reciprocating movement can drive the scraper to rotate back and forth, so that the tissue can be cut better.

Principle and advantages of use: By setting the protection mechanism 2, when the device is used, when the device penetrates into the patient's body, the outer protection tube 24 can be used for auxiliary protection. At this time, the sampling needle tube 41 can be blocked, so that the sampling needle tube 41 can be well protected to avoid accidentally stabbing the patient's internal organs. When the device penetrates into the patient's body, the buffer spring 6 can also be used to buffer the bottom cap 22 and the outer protection tube 24, so that the device can have a good protective buffering effect and can avoid causing harm to the patient. In the process of use, when sampling is needed, the connecting rod 26 can be pulled by pulling the lifting frame 27, and the connecting rod 26 can pull the bottom cap 22 upward, thereby driving the protection tube to move upward, and the sampling needle tube 41 can be exposed at this time, so that the device can quickly and conveniently flexibly adjust the extension and retraction of the sampling needle tube 41, which is convenient for the sampling operation of the device, and avoids the sampling needle tube 41 accidentally sliding downward and moving out of the outer protection tube 24 to stab the human body.

By setting the sampling assembly 4, during the use of the device, the connecting hose 84 at the outer end of the sampling hose 7 can be connected to the syringe, and the tissue fluid can be collected by drawing it through the syringe. At this time, the tissue fluid is transported to the inside of the collection tank 81 through the sampling tube 3 and the delivery tube 82. When the tissue fluid needs to be taken out, the sealing cover 86 can be twisted to open the extraction tube 85 for extraction. When further cleaning is required, the sealing cover 86 at the bottom can be opened, and the inside of the collection tank 81 can be quickly cleaned, making the device easy to clean;

By setting up the sampling component 4, during use of the device, the connecting rod 26 can be driven to slide on the inner side of the reinforcement sleeve 28 by pulling the lifting frame 27, so that the bottom cap 22 can be quickly pulled by the connecting rod 26, and the bottom cap 22 can be pulled to drive the internal threaded sleeve 23 to move. Since the internal threaded sleeve 23 and the external threaded sleeve 42 are threadedly connected to each other, the sampling needle tube 41 can be driven to rotate by the thread. The rotation of the sampling needle tube 41 can drive the sampling scraper 43 to rotate. At this time, the lifting frame 27 is released again, and the telescopic spring 21 is reset to drive the bottom cap 22 to move downward. The reciprocating movement can drive the scraper to rotate back and forth, so that the tissue can be better cut, so that the device can efficiently sample the tissue.
