[0026] The tissue sample sampling pen in this embodiment has a simple structure, is easy to use, and better meets the sampling needs of operators. Among them, a pen tip 210 is set at the front end of the pen head 200, and the pen tip 210 is a hollow structure, which is convenient for punching holes during the sampling process. Secondly, the pen tip 210 is provided with a preset angle, which is convenient for cutting tissue sampling, obtaining tissue samples of a larger area, and improving the sampling efficiency. It satisfies the user to operate according to specific needs. The specific operator can punch a hole in the tissue sample through the pen tip 210, and then push the push rod 310, so that the push rod 310 drives the sample ejector to the pen tip 210, thereby pushing out the sampled tissue in the pen tip 210. In addition, the pen core 300 is composed of the push rod 310 and the sample ejector, and the pen core 300 can be telescopically moved along the axial direction of the pen body 100, thereby improving the sampling efficiency of the tissue sample sampling process.
[0027] In one of the specific embodiments, a spring 330 is provided at the connection end between the push rod 310 and the sample ejector, and both the push rod 310 and the sample ejector are retractable along the axial direction of the pen body 100. In this embodiment, it should be noted that, compared with the push-type tissue sample sampler 320, the tissue sample sampling pen of the present application is provided with a spring 330, and the push rod 310 is directly pressed without continuous pushing, thereby improving the sampling efficiency of the tissue sample sampling process. In addition, the push-type sampler 320 needs to consider the sealing of the device, and its service life is relatively low. However, the sampling pen of the present application has a longer service life, and is simple to operate and easy to use.
[0028] In one specific embodiment, the inner circumference of the pen tip 210 matches the outer circumference of the ejector.
[0029] In one specific embodiment, the preset tilt angle of the pen tip 210 is 30 degrees to 85 degrees. In this embodiment, it should be noted that the preset tilt angle of the pen tip 210 is preferably 70 degrees. The 70-degree bevel angle is convenient for cutting, and the sharp edge is convenient for cutting. It should also be noted that the size of the pen tip 210 is preferably 2mm-3mm. The pen tip 210 can be replaced by a pinhole, which not only makes the device assembly more convenient, but also reduces the production cost and is easy to promote.
[0030] In one specific embodiment, the sample ejector is detachably connected to the push rod 310, and the pen body 100 is detachably connected to the pen tip 200. In this embodiment, it should be noted that it is convenient for the operator to replace sample ejectors of different specifications and corresponding pen tips 200 according to actual conditions to sample different tissue samples.
[0031] In one specific embodiment, the ratio of the length of the pen body 100 to the length of the pen core 300 is 1:2-4:5. In this embodiment, it should be noted that the length of the pen body 100 is preferably 12 cm, and the length of the pen core 300 is preferably 17 cm-18 cm. It should also be noted that the length of the push rod 310 is preferably 5 cm-6 cm.
[0032] In one specific embodiment, a limiting portion 311 is provided at the front end of the push rod 310, and the sample ejector is provided inside the pen body 100; the sample ejector is provided at the middle of the limiting portion 311, and the rear end of the sample ejector is provided at the rear end of the limiting portion 311, and the outer periphery of the limiting portion 311 conflicts with the inner periphery of the knife edge. In this embodiment, it should be noted that the push rod 310 is prevented from driving the sample ejector to fall off from the knife edge, thereby improving the safety of the tissue sample sampling pen.
[0033] In one of the specific embodiments, a fixed disk 312 is provided at the free end of the push rod 310, and the outer periphery of the fixed disk 312 conflicts with the rear end of the pen body 100. In this embodiment, it should be noted that the diameter of the fixed disk 312 is greater than the diameter of the rear end of the pen body 100. The free end of the push rod 310 is limited to prevent the push rod 310 from falling off at the knife edge, causing the sample ejector to extend too much and accidentally injure the operator. On the other hand, the free end of the push rod 310 is provided with a fixed disk 312, and the surface of the fixed disk 312 is smooth and has a sense of design, making the overall appearance of the tissue sample sampling pen more beautiful. It should also be noted that an extension is provided at the outer periphery of the rear end of the pen body 100, and the rear end of the extension is in contact with the front end of the fixed disk 312. The safety of the tissue sample sampling pen is improved to prevent the fixed disk 312 from clamping the back of the operator's hand holding the pen body 100 when the operator holds the pen body 100 with one hand and presses the push rod 310 with the other hand.
[0034] In one specific embodiment, it further includes: a pen cap 400; the pen cap 400 is arranged at the front end of the pen tip 200, and the size of the pen cap 400 matches the size of the pen tip 200. In this embodiment, it should be noted that the blade of the pen tip 210 is protected from being worn, and on the other hand, the sample ejector is prevented from not being retracted into the pen body 100 in time, which causes the sample ejector and the pen tip 210 to scratch the operator, thereby ensuring the safety of the tissue sample sampling pen. It should be further noted that the front end of the pen cap 400 is at a certain distance from the front end of the pen tip 210.
[0035] In one specific embodiment, it further includes: a pen hanger 500; the pen hanger 500 is arranged at the rear of the pen body 100, and the rear end of the pen hanger 500 is flush with the rear end of the pen body 100. In this embodiment, it should be noted that it is convenient for the operator to carry it with him, and the sampling pen after collection is placed in a fixed position through the pen hanger 500 to avoid accidental touch by other people.
[0036] In summary, it should be noted that the center line of the sample ejector is in the same straight line as the center line of the push rod 310; the center line of the sample ejector is in the same straight line as the center line of the pen head 200; the center line of the push rod 310 is in the same straight line as the center line of the pen body 100. This allows the sample ejector to extend directly out of the blade and maintain the regularity of the internal layout of the tissue sample sampling pen. It should also be noted that the outer periphery of the pen body 100 is provided with scales, which is convenient for the operator to view the scales of the pen body 100 according to actual needs, thereby adjusting the length of the sample ejector to be extended.
[0037] It should be noted that, although the tissue sample sampling pen is introduced as an example in this application, those skilled in the art will understand that this application should not be limited thereto. In fact, users can flexibly set it according to personal preferences and / or actual application scenarios, as long as it is reasonable.
[0038] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
