Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a cervical live sampling forceps designed to prevent falling. Background Technology

[0002] In existing cervical biopsy techniques, traditional sampling forceps typically consist of two arms, which are manually operated to grasp tissue samples. These forceps are designed primarily to rely on the serrations or textures of the forceps heads to increase friction and prevent tissue from slipping out during the sampling process.

[0003] However, traditional sampling forceps often fail to provide sufficient gripping force when grasping soft or slippery tissues, causing the tissue to easily slip during the sampling process, affecting the accuracy and success rate of sampling. Since the sampling forceps lack an effective anti-drop mechanism, once the tissue falls off during the sampling process, not only does it require re-sampling, but it may also increase the patient's discomfort and infection risk. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a cervical live sampling forceps that prevents it from falling off, so as to improve the problems existing in the prior art.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: a cervical live sampling forceps that prevents falling, comprising a fixed handle, a fixed circular block connected to the fixed handle, a movable handle rotatably connected to the fixed circular block, an extension block connected to the side of the fixed circular block away from the fixed handle, an outer tube connected to the side of the extension block away from the fixed circular block, a lower forceps head connected to the side of the outer tube away from the extension block, an upper forceps head rotatably connected to the lower forceps head, a push rod slidably connected inside the outer tube, the push rod being movably connected to the upper forceps head, and the push rod being movably connected to the movable handle; a plurality of micro suction heads are provided on the side of the upper forceps head near the lower forceps head, and the micro suction heads adsorb the sample by negative pressure suction.

[0006] A negative pressure source is installed at the end of the push rod away from the upper clamp head. The negative pressure source is connected to the miniature suction head through a conduit located inside the outer tube.

[0007] A fixing block is provided on the side of both the fixed handle and the movable handle that are close to each other. A spring is provided inside each fixing block. The spring engages to reset the movable handle.

[0008] The lower clamp head is equipped with evenly distributed crossbars to prevent the sample from falling out.

[0009] A pressure switch is provided on the upper clamp head, which is used to control the start of the negative pressure source.

[0010] An electromagnet is provided on the upper clamp head, and an iron block is provided on the lower clamp body. The electromagnet is electrically connected to the pressure switch.

[0011] The fixed handle is equipped with a main switch, which is electrically connected to the electromagnet and the negative pressure source.

[0012] Compared with the prior art, the advantages of this utility model are: by setting a miniature suction head, when the upper and lower jaws are closed, the negative pressure source is activated by a pressure switch, so that the miniature suction head can attract the sample, effectively preventing the sample from falling; and by setting an electromagnet and an iron block, when the upper and lower jaws are closed, the electromagnet is energized and attracts the iron block, so that the non-movably connected end of the upper and lower jaws can fit more tightly, further ensuring the clamping effect of the upper and lower jaws and preventing the sample from falling.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In this description of the utility model, "a number" means two or more, unless otherwise explicitly specified.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0024] It should also be understood that the terminology used in this specification of embodiments of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the present invention. As used in this specification of embodiments of the present invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0025] Specific embodiments of this utility model are shown in the appendix. Figure 1 - Appendix Figure 4As shown, a cervical live sampling forceps designed to prevent drop includes a fixed handle 1, a fixed circular block 2 connected to the fixed handle 1, a movable handle 3 rotatably connected to the fixed circular block 2, an extension block 4 connected to the right side of the fixed circular block 2, an outer sleeve 5 connected to the right side of the extension block 4, a lower clamp head 6 connected to the right side of the outer sleeve 5, an upper clamp head 7 rotatably connected to the lower clamp head 6, a push rod 8 slidably connected inside the outer sleeve 5, the push rod 8 being movably connected to the upper clamp head 7, and the push rod 8 being movably connected to the movable handle 3. When the movable handle 3 rotates towards the fixed handle 1, the push rod 8 moves to the right, thereby pushing the upper clamp head 7 to rotate, cooperating with the lower clamp head 6 to clamp the sample. Multiple micro-suction heads 9 are provided on the side of the upper clamp head 7 near the lower clamp head 6, and the micro-suction heads 9 adsorb the sample by negative pressure suction.

[0026] A negative pressure source 10 is installed at the end of the push rod 8 away from the upper clamp head 7. The negative pressure source 10 is connected to the miniature suction head 9 through a conduit 11, which is located inside the outer tube 5.

[0027] A fixing block 12 is provided on the side of the fixed handle 1 and the movable handle 3 that are close to each other. A spring piece 13 is provided in the fixing block 12. The spring piece 13 cooperates to reset the movable handle 3.

[0028] The lower clamp head 6 is provided with evenly distributed crossbars 14 to prevent the sample from falling.

[0029] A pressure switch 15 is provided on the upper clamp head 7. The pressure switch 15 is used to control the start of the negative pressure source 10. When the upper clamp head 7 rotates to close with the lower clamp head 6, the pressure switch 15 is squeezed, controlling the start of the negative pressure source 10, so that the micro suction head 9 can attract the sample. At this time, the upper clamp head 7 and the lower clamp head 6 are in a closed state, that is, the sample is clamped. With the attraction of the micro suction head 9, the sample can be effectively prevented from falling.

[0030] An electromagnet 16 is provided on the upper clamp head 7, and an iron block 17 is provided on the lower clamp body. The electromagnet 16 is electrically connected to the pressure switch 15. When the pressure switch 15 is squeezed and the negative pressure source 10 is activated, the electromagnet 16 is also energized, attracting the iron block 17, so that the right side of the upper clamp head 7 can close with the lower clamp head 6, ensuring the clamping effect and preventing the sample from falling.

[0031] The fixed handle 1 is provided with a main switch 18, which is electrically connected to the electromagnet 16 and the negative pressure source 10. When it is necessary to release the sample, the main switch 18 is pressed, so that the negative pressure source 10 and the electromagnet 16 are de-energized. Then the movable handle 3 is reversed, so that the upper clamp head 7 rotates to release the sample.

[0032] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
