Description
Technical field
This utility model relates to technical field of medical instruments, refers to a kind of tumor sampling device especially.
Background technology
As everyone knows, successfully can be realized by operative incision when carrying out body-surface tumor active check sampling to patient clinically, but the misery can brought to patient due to operative incision is comparatively large, therefore the general syringe that adopts samples, by means of the negative pressure absorbing tumor tissues that syringe produces more at present.But the sampling of the tumor at some position of health does not realize by operative incision, such as: bladder, although tumor tissues can be drawn by syringe, bladder cannot be entered by urethra, cortex must be pierced through and could draw tumor tissues, still can bring larger misery to patient.So we need to provide a kind of tumor sampling device, carry out painless tumor sampling device according to organization of human body.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of tumor sampling device, can carry out painless tumor sampling device according to organization of human body.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of tumor sampling device, comprise negative pressure device and sampler, described sampler comprises guiding tube, probe tube and syringe needle, described negative pressure device comprises outer tube and is located at the interior pipe in outer tube, described probe tube is located in guiding tube, probe tube one end is located at by described syringe needle, end, described guiding tube one end is provided with leading end, described leading end center is provided with the through hole suitable with syringe needle, the described guiding tube other end is connected to outer tube front end, the described probe tube other end extends in outer tube and is connected with interior pipe forward end seal, to be tightly connected with inner tube wall piston and the piston rod that is fixedly connected with piston back center place is provided with in described interior pipe.
As preferably, described leading end is type structure spherically, and described guiding tube is rubber tube.
As preferably, described piston rod other end end vertical is provided with the first push rod, and described interior pipe tail end is provided with the second push rod connected vertically.
As preferably, described syringe needle is positioned at leading end and is slidably connected with through-hole wall.
The beneficial effect of technique scheme of the present utility model is as follows: structure is simple, technology is reasonable, and the guiding tube made by rubber tube, according to organization of human body, enter in human body, and can not cause suffering to patient, such as, tumor is longer than bladder place, enter by urethra, when the leading end of guiding tube reaches predetermined position, in guiding tube, release the absorption that syringe needle carries out tumor tissues, operation is very easy.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of tumor sampling device embodiment of the present utility model.
Fig. 2 is the enlarged diagram of leading end in Fig. 1.
Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
This utility model provides a kind of tumor sampling device for existing deficiency, as shown in Figure 1, comprise negative pressure device and sampler, described sampler comprises guiding tube 4, probe tube 3 and syringe needle 2, the interior pipe 6 that described negative pressure device comprises outer tube 5 and is located in outer tube 5, described guiding tube 4 is rubber tube, because rubber tube has soft characteristic, when guiding tube 4 enters human body inside according to organization of human body, to the histiocyte of inside of human body, there is good protective effect, described probe tube 3 is located in guiding tube 4, probe tube one end is located at by described syringe needle 2, end, described guiding tube 4 one end is provided with guiding 1 end, described guiding tube 4 other end is connected to outer tube 5 front end, described probe tube 3 other end extends in outer tube 5 and is connected with interior pipe 6 forward end seal, when leading end 1 arrives precalculated position, pipe 6 in promoting, make the end of syringe needle 2 can skid off leading end 1 pair of tumor tissues to sample, the piston rod 10 being connected piston 9 with interior pipe 6 inner wall sealing and being fixedly connected with piston 9 back center place is provided with in described interior pipe 6, subnormal ambient is realized by the piston 9 that matches and interior pipe 10, thus tumor tissues is sampled, described piston rod 10 other end end vertical is provided with the first push rod 8, described interior pipe 6 tail end is provided with the second push rod 7 connected vertically, be convenient to promote piston rod 10 and interior pipe 6 by the first push rod 8 and the second push rod 7.
As shown in Figure 2; described leading end 1 spherically type structure; to the histiocyte of inside of human body, there is good protective effect; described leading end 1 center is provided with the through hole suitable with syringe needle 2; described syringe needle 2 is positioned at leading end 1 and is slidably connected with through-hole wall; wherein, syringe needle 2 is positioned at through hole all the time.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
