[0002] Cervical conization is a gynecological operation, which is used to remove part of the uterine cervical tissue. The operation process is to cut off a part of the cervical tissue in a conical shape from the outside to the inside. It includes loop electrosurgical excision procedure and cold knife conization. Cervical conization surgery can be used as a treatment method to remove lesions, and it can also be used for pathological examination to confirm the degree of cervical lesions. When performing pathological examination on cervical tissue, the cervical tissue specimen is usually divided into 12 points, each point is cut and sampled, and then the lesion range is detected. The existing pathological sampling device usually cuts the specimen by multiple groups of blades distributed in a ring shape. The blades are usually fixed directly on the cutter disc. When cutting, the blade group is usually pressed directly, and the blade group cuts the tissue. The blade directly presses the tissue, which may cause the tissue specimen to deform and cause damage to the tissue. This is not conducive to subsequent pathological examination of the tissue specimen. Moreover, the deformation of the tissue specimen may change the cutting position, which is not conducive to uniform and flat cutting of the tissue specimen. SUMMARY

[0027] Please refer to Figures 1-5 In the embodiments of the utility model, a pathological sampling device for cervical conization specimens comprises a base 1, a center rod 2, a sliding frame 3 and a plurality of connecting boxes 4.
[0028] The bottom end of the center rod 2 is fixedly connected to the top surface of the base 1, a plurality of strip slots 21 are formed in the side surface of the center rod 2, the sliding frame 3 is arranged on the top of the center rod 2, the plurality of connecting boxes 4 are fixedly connected to the inner side surface of the sliding frame 3, the sliding seat 41 is slidably connected to the inner side surface of the connecting box 4, the cutting knife 42 extending into the adjacent strip slot 21 is fixedly connected to the inner side surface of the sliding seat 41, and the thickness of the strip slot 21 is greater than the thickness of the cutting knife 42, so that the cutting knife 42 can move in the strip slot 21.
[0029] Specifically, the tissue specimen is put on the central rod 2, and then the sliding frame 3 is moved from the top of the central rod 2 to the central rod 2, so that the ends of the cutting knives 42 close to each other pass into the corresponding strip grooves 21, and then the sliding frame 3 can be moved downward along the central rod 2, and the connecting box 4 can be driven downward by the sliding frame 3. The connecting box 4 can drive the cutting knife 42 to move downward through the sliding seat 41, so that the cutting knife 42 moves downward to cut the tissue specimen. During the cutting process, the sliding seat 41 can be made to slide inside the connecting box 4, and the cutting knife 42 can be driven to move back and forth along the horizontal plane by the sliding seat 41, so that the cutting knife 42 slides and cuts the tissue specimen.
