Description

Pathological operation sample device of drawing materials

Technical Field

The utility model relates to a specimen taking device for pathological operation.

Background

The pathology is the medical science which researches the change of etiology, pathogenesis, morphological structure, function, metabolism and the like of the disease, reveals the occurrence and development rules of the disease and explains the essence of the disease. The current pathological operation specimen cutting (material taking) mode is as follows: a pathologist fixes a specimen by one hand, holds a material taking knife handle with a blade by the other hand, cuts the specimen in a page shape at intervals of 5mm, observes the position, size, shape, texture, relation with surrounding tissues and the like of pathological changes in the specimen, and then cuts a plurality of tissue blocks with the thickness of 3mm and the area of not more than 20mm multiplied by 15mm according to needs to perform subsequent pathological work such as fixing, dehydrating, embedding, making pathological sections, microscopic examination and the like. The material taking method is complicated, time-consuming, labor-consuming, difficult and occupational exposure risk exists.

The defects of the existing material taking method are as follows: firstly, it cannot be ensured that the dissected tissue is parallel (parallel dissection is a crucial requirement for obtaining surgical specimens), and the reasons for this disadvantage are: 1. when the operation specimen is cut, a pathologist needs to fix the specimen with one hand and hold the knife handle with the other hand to drag the blade to cut the specimen, and due to the fact that the blade is dragged manually, dragging tracks are not straight lines due to human factors; 2. the blade dragging process may cause uneven resistance due to uneven texture, uneven thickness or partial tissue calcification of the specimen, and the dragging track is not straight. Secondly, the width of the tissue after cutting is not ensured to be 5mm (the cutting of the page shape with the interval of 5mm is the key element of the material obtaining of the operation specimen), and the reasons for the defect are as follows: 1. because the blade is dragged manually, the cutting width is required to be 5mm, and the width of 5mm is not easy to perform manual cutting operation standards, the cutting width of part of tissues is not 5mm due to human factors; 2. the dragging process of the blade can cause uneven resistance due to uneven texture, uneven thickness or partial calcification of tissues of the specimen, and the dragging track is not a straight line, so that the partial tissue dissection width is not even 5 mm. Thirdly, the material taking process wastes time and labor, and the reason for causing the defect is as follows: 1. the operation specimen is manually cut into a piece of tissue with the width of 5mm, which wastes time and labor; 2. the so-called "leaf-shaped incision" means that although the tissues are incised at intervals of 5mm, a small part (generally required to be 3mm thick) of the bottom of the tissues is connected like the "leaves", the purpose is to observe the relationship between the adjacent tissues, and the incision is completely completed by hand, which means that the examination technology is time-consuming and labor-consuming; 3. the operation specimen is 'page-shaped incision', after the condition of the specimen is observed, a plurality of tissue blocks with the thickness of 3mm and the area of not more than 20mm multiplied by 15mm are cut according to the pathological change requirement to carry out subsequent pathological work, and the tissue with the thickness of 3mm is cut by the tissue with the thickness of 5mm, which is time-consuming and labor-consuming. Fourthly, the physician is easy to be injured, and the reason for the defect is that: 1. because the pathological operation specimens are different in size and irregular in shape, and part of the specimens are extremely sticky and smooth, the specimen taking process is fixed by one hand and cut by the other hand, and the hand for fixing the specimens is easily accidentally injured by the specimen taking blade; 2. the tissue with the thickness of 5mm is cut from the operation specimen, and the tissue with the thickness of 3mm is cut from the tissue with the thickness of 5mm, which are both manually completed, and the cutting process of a sampling physician is easy to be injured.
