Abstract
The utility model discloses a tissue chip sampler used for target tissue sampling, which is one of the preparation apparatus of tissue chips, and comprises a hollow needle tube used for getting a target tissue, a handle and a movable needle core, wherein the handle part of the needle core is provided with a spring, when the hollow needle tube is inserted into a certain thickness of the target tissue, and the needle core with a handle is pressed with a hand after being pulled out, the target tissue which is gotten automatically withdraws to a hollow wax mould and is embedded and then slice. The utility model has the advantages of convenient and fast operation, complete columnar organization which is gotten, less time and labor consumption, improved efficiency of target issue and high value of practical application.
Description
One, affiliated technical field
The utility model relates to the sampling equipment of tissue morphology destination organizations such as biology, zoology and medical science, particularly various histocyte samples, comprises the organization chip sampler of tumour and other destination organization.
Two, background technology
Organization chip destination organization sampling adopts puncture needle to replace sampling at home at present, before the sampling pin heart is return or is extracted out, has got behind the tissue pin heart insertion release again.The problem of using puncture needle to exist is, puncture needle is thinner on the one hand, and the bad pin of holding is got several objects and organized all rightly, gets tens, operating personnel's hand is prone to fatigue behind the hundreds of destination organization.On the other hand, dangerous property during operation, puncture needle punctures the palm of the hand that operating personnel hold wax through regular meeting.In addition, operating speed is slow, and efficient is low.
Three, summary of the invention
At defective or the deficiency that above-mentioned prior art exists, the purpose of this utility model is, a kind of puncture needle is provided and withdraws from the nook closing member organization chip sampler that is combined as a whole automatically.
Realize that the above-mentioned purpose technical scheme is, this organization chip sampler, comprise that one is used for the hollow puncture needle tubing of destination organization sampling, bag is carried out needle handle is arranged on the external diameter of puncture needle tubing, be characterized in, the internal diameter of puncture needle tubing also is combined with the nook closing member that the destination organization sample withdraws from that is used for of a solid band handle, is provided with spring at an end that withdraws from the nook closing member shank.
Another characteristics of the present utility model are that the syringe needle of described puncture needle tubing is flush or has tapering.
The utility model is because the employing integrated design is easy to operate, safe and reliable, do not need the empty needle of withdraw of the needle puncture, be convenient to hold pin, overcome the pushing phase work fatigue of operating personnel effectively and by the danger of pricking wound, can improve sample rate, the destination organization column of getting is complete.
Four, description of drawings
Fig. 1 is a structural drawing of the present utility model.
Five, embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, organization chip sampler of the present utility model, comprise that one is used for the hollow puncture needle tubing 1 of destination organization sampling, bag is carried out needle handle 2 is arranged on the external diameter of puncture needle tubing 1, the internal diameter of puncture needle tubing 1 also is combined with the nook closing member 3 that the destination organization sample withdraws from that is used for of a solid band handle, is provided with spring 4 at an end that withdraws from nook closing member 3 shanks.
The syringe needle of puncture needle tubing 1 is flush or has tapering.
When making, needle handle is selected organic glass or other material for use, and as plastics etc., that can do is thicker, hold so pleasant, to alleviate labor intensity of operating personnel.It withdraws from nook closing member 3 and extrudes the back nook closing member through spring and can expose the puncture needle tubing, can work as like this after hollow needle tubing inserts the destination organization certain thickness, extracts the nook closing member of back with hand band handle, and the interior destination organization sample of needle tubing that guarantees to puncture is pushed out smoothly.
During use, only need hold sampler, insert and to obtain destination organization, when waiting to enter certain thickness, extract the puncture needle tubing, use the nook closing member of thumb pressure zone handle again, can release the destination organization sample in the puncture needle tubing, send into embedding again in the hollow wax matrix, cut into slices then.
The utility model is convenient to operation, and organizing of getting is complete, and dependable performance saves time, laborsaving, has improved the efficient of getting destination organization greatly, has good actual application and is worth.
Claims (2)
