Description

Technical Field

[0001] This utility model relates to the field of specimen collection technology, and in particular to a cervical specimen collection device for gross specimens. Background Technology

[0002] Cervical cancer is one of the most common malignant tumors of the female reproductive system. For pathological diagnosis, standardized specimen collection is fundamental and crucial. Cervical conization specimens obtained by the pathology department are of great significance for diagnosing the location, depth, and extent of cervical lesions. During collection, the cervical resection specimen needs to be marked according to orientation: the center of the anterior lip is marked as "12 o'clock," and the center of the posterior lip as "6 o'clock." Before collection, the exposed fibrous stroma and the mucosal margins of the external cervical os are marked with ink, and the thickness of the inner and outer cervical margins and the length of the conized specimen are measured. During collection, starting from the 12 o'clock position, a series of full-thickness tissue samples are sequentially cut from the vertical section of the cervical canal mucosa in a clockwise direction, ensuring that each specimen contains the entire mucosa from the inner side of the cervical canal to the external cervical os.

[0003] Currently, pathology departments rely primarily on the experience of pathologists when collecting cervical samples, typically using a scalpel for direct sampling. This often results in uneven tissue division and rough cut surfaces, affecting subsequent diagnosis. Existing technologies include some research on cervical sampling instruments / devices, such as the Chinese utility model patent application number 202220570970.5, entitled "A Cervical Conization Gross Specimen Sampling Device." This device can cut cervical conization specimens into equal portions, ensuring each portion includes the mucosal layer, internal os, external os, and basal cutting edge. It works by pressing a ring-shaped pressure plate that slides along the inner wall of a cylinder, driving a blade to cut the specimen on the cylinder. However, to facilitate operation, both the ring-shaped pressure plate and the cylinder are relatively large, resulting in insufficient practicality for cervical sampling. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a cervical specimen sampling instrument that can facilitate cervical sampling and make the tissue sample uniform and the cut surface flat.

[0005] This utility model is achieved using the following technical solution: a cervical specimen sampling device, comprising a support sleeve and a cutting and sampling assembly, wherein the support sleeve is used to place a cervical specimen, and the cutting and sampling assembly is used to cut the cervical specimen placed inside the support sleeve; the support sleeve comprises a cylindrical body and a mounting post, wherein multiple through slots are symmetrically and equally distributed on the cylindrical body, and the mounting post is vertically fixed to the center of the bottom of the cylindrical body.

[0006] Furthermore, the cutting and material extraction assembly includes an outer ring, an inner ring, support bars, and a cutting blade. The inner ring is located in the center of the outer ring. Several support bars are symmetrically connected between the inner wall of the outer ring and the outer wall of the inner ring. A cutting blade is fixed at the bottom end of each support bar. The number of through slots is an integer multiple of the number of support bars, and the support bars can pass through the through slots from top to bottom. The inner diameter of the outer ring is larger than the outer diameter of the cylinder, so that the outer ring can be fitted onto the outside of the cylinder.

[0007] Furthermore, two operating handle structures are symmetrically fixed on the outer side of the outer ring for hand gripping and operating the cutting and material extraction assembly.

[0008] Furthermore, the operating grip structure includes a grip linkage and a grip, wherein the grip and the outer side of the outer sleeve are connected via the grip linkage.

[0009] Furthermore, the top of the mounting post is provided with threads on the outer side, and a pressure ring is installed on the top of the mounting post through thread engagement. The outer diameter of the pressure ring is smaller than the inner diameter of the inner ring, so that the inner ring can pass through the pressure ring.

[0010] Furthermore, a base plate is fixed to the bottom end of the cylinder, and the base plate is provided with a number of fixing holes.

[0011] Furthermore, there are six support bars and six through slots.

[0012] Furthermore, there are six support bars and twelve through slots.
