Abstract
The invention discloses a kind of pet tumor examination samplers, it includes the puncture needle tubing (1) of a generally hollow tubular structure, the side of puncture needle tubing (1) end is axially outwardly extended guide plate concentric with it (2), and the end of the guide plate (2) is provided with the sloping desk (3) as piercing needle；Puncture needle tubing (1) is internally provided with the first piston (4) being closely slidably matched with it and second piston (5), is fixed into an entirety by connecting rod (6) between the first piston (4) and second piston (5).The configuration of the present invention is simple can puncture the tumor tissues of various quality, and can successfully extract the tissue samples of inside tumor, provide guarantee for the quality scheme and the course for the treatment of in later period.
Description
Technical field
The present invention relates to the relevant technical fields of Medical pet equipment, and in particular to be a kind of pet tumor examination
Sampler.
Background technique
Tumor aspiration biopsy is one of the important means of determining tumour property, by cytolgical examination after puncturing, is determined swollen
Tumor be it is benign or pernicious, the sampling mode of common puncture needle is broadly divided at present: 1. directly extract inside tumor tissue fluid
Needle point formula biopsy needle；2. being provided with the biopsy needle that needle point hooks up inside tumor tissue in needle tip；3. hollow tricuspid hair style
The Biopince cell taking gun of tumor surface tissue can directly be taken；
Although the inside that above several puncturing structures biopsy needle first can be punctured to tumour is sampled, its disadvantage
It is also can exist and be not easy to grab or be drawn into internal tissue or tissue fluid it will be apparent that if tumor tissues are harder,
And be the cell taking gun needle body of representative compared with tumor tissues slightly harder conducive to crawl quality using Biopince, but due to its structure
Limitation can only grab the surface texture of tumour, and often there is biggish differences compared with whole for the surface texture of sampling
It is anisotropic.
Summary of the invention
It is an object of the present invention to provide a kind of pet tumor examination samplers, it can efficiently solve in background technique and be deposited
The problem of.
In the presence of solving the problems, such as background technique, it includes the puncture needle tubing of a generally hollow tubular structure
1, guide plate 2 concentric with it, the end setting of the guide plate 2 are axially outwardly extended in the side of 1 end of puncture needle tubing
There is the sloping desk 3 as piercing needle；
The needle tubing 1 that punctures is internally provided with the first piston 4 being closely slidably matched with it and second piston 5, this
An entirety is fixed by connecting rod 6 between one piston 4 and second piston 5, the upper end of the first piston 4 axially upwardly extends
Boss 7 out are provided with external screw thread at the periphery of the boss 7, and the upper end of the boss 7 is fixed with a piston concentric with it
Bar 9, the end of the piston rod 9 pass through puncture needle tubing 1 and positioning sleeve 10 and are fixedly connected with control bracelet 11, the positioning sleeve 10
Be screwed on the upper end for being fixed on and puncturing needle tubing 1, and the inside of the positioning sleeve 10 offers the internal screw thread for the cooperation that can be screwed on boss 7；
Sampling plate 8 is axially outwardly extended in the side of 5 lower end surface of second piston, which can generally paste
It closes guide plate 2 and punctures and slide arcuate structure at 1 inner wall of needle tubing, the lower end one-pass molding of the sampling plate 8 goes out to be fitted in
Sampling panel 12 on sloping desk 3, the periphery of the sampling panel 12 are provided with a circle scraper 13, the periphery of the scraper 13
It place can be with puncture 1 clearance sliding fit of needle tubing.
When sampling panel 12 and sloping desk 3 contacts, the second piston 5, which is located at, to be punctured in needle tubing 1.
After boss 7 and positioning sleeve 10 are screwed on cooperation, the scraper 13, which is fully located at, to be punctured in needle tubing 1.
Each germplasm can be punctured the invention has the following advantages: structure is simple due to using above technical scheme
The tumor tissues on ground, and the tissue samples of inside tumor can be successfully extracted, it is provided for the quality scheme and the course for the treatment of in later period
It ensures.
Detailed description of the invention
