Description

Technical Field

[0001] The utility model relates to the field of model preparation equipment, in particular to a device for accurately constructing a soft tissue defect model. Background Art

[0002] Constructing an animal model of disease or injury is one of the important links in human research on the pathogenesis of disease and injury and in finding treatment methods. An animal model that is simple to make, reproducible, reliable, and repeatable helps to ensure the quality of clinical research. When constructing a tissue defect model, it is necessary to cut a notch in the tissue; in the prior art, tissue is generally removed by scissors. However, in the prior art, due to factors such as the operation of the experimenter, the position, size, and size of the model are easily inconsistent, thereby affecting the accuracy and results of subsequent experiments. This modeling method makes it difficult to ensure the accuracy of the cutting; there are also some tools in the prior art that can be used to cut sample tissues.

[0003] For example, the patent with authorization announcement number CN210056317U discloses an instrument for accurately implementing animal tendon / ligament injury modeling, including a pair of articulated bodies, a pair of modeling bodies and a pair of gripping handles. The two articulated bodies are hinged to each other, each modeling body is correspondingly arranged at one end of the articulated body, and each gripping handle is correspondingly arranged at the other end of the articulated body. The modeling body includes an indicating unit and a cutting unit. The indicating unit contains a scale member, which is in the shape of a rectangular parallelepiped and has an outer surface, an inner surface, a first side, a second side, a third side and a fourth side. The cutting unit contains a first cutting knife, a second cutting knife and a third cutting knife, all of which are rectangular. The first cutting knife has a first blade end, the second cutting knife has a second blade end, and the third cutting knife has a third blade end. The outer surface of the scale member is provided with a first scale line, a second scale line and a third scale line.

[0004] When cutting tendons / ligaments, the above patent uses a cutting unit to cut the tissue, and an indicator unit (scale line) provided on the surface of the model body is used to indicate the positioning; however, the above patent has the disadvantage that when cutting, when the thickness of the cut tissue is greater than the height of the cutting knife, the cut tissue will be squeezed by the bottom of the scale piece, which will damage the surrounding tissue and affect the effect and quality of the modeling.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of the present invention is to provide a device for accurately constructing a soft tissue defect model to solve the problems raised in the above-mentioned background technology.

[0024] 3. During cutting, the cut part is removed from the top of the cavity in the center of the cutting blade, which has little impact on the surrounding tissues of the model, and the accuracy and quality of the model are higher;

[0025] 4. At the same time, after a cut is completed, the excised sample tissue is stored in the cavity of the cutting blade, and the cut tissue will not interfere with the next cut; at the same time, after the cavity is filled with sample tissue, the subsequent cut tissue can push out the tissue at the top of the cavity.
