Example (b):
referring to fig. 1-4, a biopsy sampler convenient for sampling comprises a handle 1 with a hollow structure and a sampling mechanism arranged at the front end of the handle 1, wherein the sampling mechanism comprises a rod part 2 and a sampling chuck 3 arranged at one end of the rod part 2; two limiting rings are arranged in the inner cavity of the handle 1, a piston sheet 5 is arranged between the two limiting rings in the inner cavity of the handle 1, the end of the rod part 2 far away from the sampling chuck 3 extends into the inner cavity of the handle 1 and is coaxially connected with one surface of the piston sheet 5, the other surface of the piston sheet 5 is fixedly connected with a push rod 6, the push rod 6 extends to the outside of the handle 1 from one end of the handle 1 far away from the sampling mechanism, and a spring 7 is arranged between the piston sheet 5 and the limiting sheet 4 close to one side of the sampling mechanism; the end of the handle 1 provided with the sampling chuck 3 is connected with a sample suction pipe 8, the sample suction pipe 8 is coaxially connected with the handle 1 through a conical sleeve cap 9, and the conical sleeve cap 9 is hermetically connected with the sample suction pipe 8 and the end of the handle 1; the inner diameter of the sample suction pipe 8 is larger than or equal to the diameter of the rod part 2, the sampling chuck 3 is made of two hard elastic metal wires which can be clamped mutually, and the maximum distance between the two hard elastic metal wires is larger than the inner diameter of the sample suction pipe 8.
In this embodiment, the initial position of the sampling chuck 3 in the biopsy sampler is located at one end of the sample suction tube 8 close to the conical sleeve cap 9, because the sampling chuck 3 of the sampling mechanism is made of two hard elastic metal wires which can be clamped with each other, the maximum distance between the two hard elastic metal wires is larger than the inner diameter of the sample suction tube 8, when the sampling chuck 3 is located in the inner cavity of the sample suction tube 8, the two metal wires are compressed in the inner cavity of the sample suction tube 8; when the biopsy sample in the sampling groove of the puncture needle is a formed tissue sample, a medical worker holds a handle 1 of the biopsy sampler by hand, then pushes a push rod 6 by a thumb to drive a rod part 2 of the sampling mechanism to extend forwards, so that a sampling chuck 3 of the sampling mechanism extends out of an inner cavity of a sample suction tube 8, therefore, two hard elastic metal wires of the sampling chuck 3 are opened, the medical worker uses one metal wire to stir the biopsy sample in the sampling groove to a position which is convenient to clamp by the sampling chuck 3, and then the two metal wires of the sampling chuck 3 are used for clamping the biopsy sample; the push rod 6 is loosened slightly, the piston sheet 5 is pushed to move backwards under the action of the elastic force of the spring 7, the sampling chuck 3 slowly returns to the sample suction pipe 8, the maximum distance between the two hard elastic metal wires of the sampling chuck 3 is larger than the inner diameter of the sample suction pipe 8, so the sampling chuck 3 can gradually clamp the biopsy sample sheet in the sampling groove of the puncture needle in the retraction process, then the position of the push rod 6 is kept, the sampling chuck 3 clamps the biopsy sample, and the biopsy sample is transferred to the sampling bottle with the preservative. When the biopsy sample in the sampling groove of the puncture needle is a rare viscous sample, the piston sheet 5 of the push rod 6 is pushed to move forwards, the rare viscous biopsy sample is stirred together by the hard elastic metal wire of the sampling chuck 3 and gathered, then the sampling chuck 3 is recovered to the inner cavity of the sample suction pipe 8, the end of the sample suction pipe 8 extends into the rare viscous biopsy sample, the push rod 6 is loosened slightly, the piston sheet 5 is pushed to move backwards by the spring 7, the rare viscous biopsy sample in the sampling groove of the puncture needle is sucked into the sample suction pipe 8, then the sample suction pipe 8 is moved into an anticorrosive sampling bottle, and the push rod 6 is pushed to place the rare viscous biopsy sample into the sampling bottle. The front end of the sample suction pipe 8 in the embodiment is a slender glass pipe, and is similar to the front end structure of a rubber head dropper; during the sample suction process, medical staff can also observe the suction condition of the biopsy sample in the sample suction pipe 8. In this embodiment, the two stop rings limit the piston plate 5 between the stop rings, which prevents the piston plate 5 from being pushed out of the inner cavity of the handle 1 during operation.
In actual use, the pjncture needle need carry out a lot of puncture samples to the patient, for the sample chuck 3 that prevents the sampler and inhale the liquid contact back in appearance pipe 8 and the sampling bottle, next sample can produce the pollution to the puncture needle, can with the help of the pole portion end of cotton swab with the sample chuck 3 go up the biopsy sample of pressing from both sides the clamp or inhale the sample pipe 8 in the thin viscidity's of release biopsy sample choose into the sampling bottle in, guarantee the sample chuck 3 and the sample pipe 8 of inhaling of sampler not contact with the sampling bottle.
The piston piece 5 is provided with the screw hole with 2 hookup locations in sampling mechanism pole portion, and pole portion 2 is provided with the screw thread with screw hole assorted in the end of being connected with piston piece 5, and pole portion 2 passes through threaded connection with piston piece 5. The pole portion 2 of the sampling mechanism in this embodiment can be dismantled with piston piece 5 through the screw thread and be connected, can pull down original sampling mechanism after the sample, installs new sampling mechanism again, and easy dismounting has also avoidd that sampling mechanism used repeatedly is the problem that causes cross contamination.
The threaded hole on the piston plate 5 penetrates through the piston plate 5 and extends to the middle position of the rod part 2. The length of the rod part 2 of the sampling mechanism in the piston sheet 5 or the push rod 6 can be adjusted, so that the exposed length of the sampling chuck 3 outside the sample suction pipe 8 is adjusted, and the sampling chuck 3 can meet the requirements of various lengths.
In the embodiment, the push rod 6 and the piston sheet 5 are integrally formed, the two limiting rings and the inner cavity of the handle 1 are integrally formed, the sample suction pipe 8 and the conical sleeve cap 9 are integrally formed, and the sample suction pipe 8 is positioned at the small-caliber end of the conical sleeve cap 9.
The large-caliber end of the conical sleeve cap 9 is movably connected with the handle 1 through threads, and a rubber sealing gasket 10 is arranged at the joint of the conical sleeve cap 9 and the handle 1. The conical sleeve cap 9 is detachably connected with the front end of the handle 1 through threads, so that the sampling mechanism can be conveniently mounted and dismounted, or when the sampling chuck 3 deforms, the sampling chuck 3 is bent again by unscrewing the conical sleeve cap 9, and the requirement for clamping a biopsy sample is met. The arrangement of the rubber sealing gasket 10 can ensure that gas cannot overflow from the joint of the conical sleeve cap 9 and the handle 1 during the movement of the piston sheet 5, thereby influencing the suction of the sample suction pipe 8 on the thin viscous biopsy sample.
The embodiment of the present invention is the above. The specific parameters in the above embodiments and examples are only for the purpose of clearly showing the verification process of the present invention, and are not used to limit the protection scope of the present invention, which is still subject to the claims, and all the equivalent structural changes made by using the contents of the specification and drawings of the present invention should be included in the protection scope of the present invention.
