Abstract
The utility model relates to a tumor tissue sampling probe which is used for extracting tissue fluid in tumor. The tumor tissue sampling probe comprises a cylinder body which is provided with a sealed cavity and of a cylinder shape, a sealing isolating membrane is arranged at the lower end of the cylinder body is a sealed mode, and the sealing isolating membrane divides the sealed cavity in the cylinder body into a vacuum cavity chamber, a probe head which can be connected on the bottom surface of the cylinder body in a sliding mode is arranged below the sealed isolating membrane, and a puncturing probe tip which is used for puncturing the sealing isolating membrane is arranged at the top end of the needle head. Due to the fact that the sealing isolating membrane divides the sealed hollow cavity in the cylinder body into the vacuum cavity chamber, when the probe head is inserted into the interior of the tumor of a patient, the cylinder body is pressed downwards, the puncturing probe tip which is arranged at the upper end of the probe head can puncture the sealing isolating membrane, and thus the vacuum cavity chamber can absorb tissue in the tumor of the patient into the vacuum cavity chamber under the function of vacuum, and the tumor tissue sampling probe is fast and convenient to use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of for the tumor tissues sampling probe at the tumor extracting interstitial fluid.
Background technology
Generally determining that patient's tumor character Shi doctor tends to insert by the tumor tissues sampling probe patient's inside tumor, then extract Cell sap and tissue in the tumor, then it is carried out assay.Such pathologic finding accuracy rate is very high.But existing tumor puncture pin all is comprised of the syringe needle that is connected in syringe and piston, thereby draws tissue fluid by the pulling piston during use, and the medical worker often needs one to hold the syringe position when extracting, and spurs on the other hand piston.Yet in the extracting interstitial fluid process owing to stop up or the other reasons medical worker needs to adjust at any time the position that is inserted into the syringe needle in the tumor, just can not extracting interstitial fluid when adjusting the position, so increased the time of taking a sample, act on behalf of misery to the patient.
Summary of the invention
This utility model provides a kind of tumor tissues sampling probe that can realize the Automatic Extraction tissue fluid after syringe needle inserts patient's in-vivo tumour in order to overcome the deficiency of above technology.
The technical scheme that its technical problem that overcomes this utility model adopts is:
This tumor tissues sampling probe, the endoporus lower end sealing that comprises the described cylindrical shell of columniform cylindrical shell with sealed cavity is provided with the vacuum chamber that the described seal dissepiment of seal dissepiment is divided into the sealed cavity in the cylindrical shell vacuum, described seal dissepiment below is provided with the syringe needle that slidably is connected in the cylindrical shell bottom surface, and described needle tip is provided be used to the needle tip that punctures seal dissepiment.
Be provided with cambered outwards projection on the above-mentioned syringe needle, spring is serially connected with on the syringe needle and is sticked between the bottom surface of projection and cylindrical shell.When syringe needle thrust patient tumors inside, syringe needle can overcome the effect of spring force when the cylindrical shell downforce acquires a certain degree during use, thereby the needle tip that is arranged under the seal dissepiment can puncture seal dissepiment.And can also not prevent under the effect of spring force that needle tip from puncturing seal dissepiment and causing and damage in advance this tumor tissues sampling probe in unnecessary situation when not using at ordinary times.
The beneficial effects of the utility model are: because seal dissepiment is divided into a vacuum chamber with vacuum with the cavity in the cylindrical shell, so when syringe needle being inserted into patient tumors inside, pressing cylindrical shell downwards can make the needle tip that is arranged on the syringe needle upper end puncture seal dissepiment, thereby vacuum chamber can be drawn into the tissue fluid in the patient tumors in the vacuum chamber owing under the effect of vacuum, and is convenient to use.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure, 1. cylindrical shell 2. seal dissepiments 3. vacuum chambers 4. graduation marks 5. needle tip 6. syringe needles 7. springs 8. projections.
The specific embodiment
Be described further below in conjunction with 1 pair of this utility model of accompanying drawing.
This tumor tissues sampling probe, the endoporus lower end sealing that comprises the columniform cylindrical shell 1 described cylindrical shell 1 with sealed cavity is provided with the vacuum chamber 3 that seal dissepiment 2 described seal dissepiments 2 are divided into the sealed cavity in the cylindrical shell 1 vacuum, described seal dissepiment 2 belows are provided with the syringe needle 6 that slidably is connected in cylindrical shell 1 bottom surface, and described syringe needle 6 tops are provided be used to the needle tip 5 that punctures seal dissepiment.Because seal dissepiment 2 is divided into a vacuum chamber 3 with vacuum with the cavity in the cylindrical shell 1, so when syringe needle 6 being inserted into patient tumors inside, pressing cylindrical shell 1 downwards can make the needle tip 5 that is arranged on syringe needle 6 upper ends puncture seal dissepiment 2, thereby vacuum chamber 3 can be drawn into the tissue fluid in the patient tumors in the vacuum chamber 3 owing under the effect of vacuum, and is convenient to use.
Be provided with the projection 8 outside protruding on the above-mentioned syringe needle 6, spring 7 is serially connected with on the syringe needle 6 and is sticked between the bottom surface of projection 8 and cylindrical shell 1.When syringe needle 6 thrust patient tumors inside, syringe needle 6 can overcome the effect of spring force when cylindrical shell 1 downforce acquires a certain degree during use, thereby the needle tip 5 that is arranged under the seal dissepiment 2 can puncture seal dissepiment 2.And can also not prevent under the effect of spring force that needle tip 5 from puncturing seal dissepiment 2 and causing and damage in advance this tumor tissues sampling probe in unnecessary situation when not using at ordinary times.
