Embodiment 1

[0034] An appliance for modeling cartilage defects in pig knees comprises a main body arranged in a tubular shape, the diameter of the inner cavity of the main body is 4mm, and the main body includes interconnected holding sections for holding and measuring A measuring section, wherein the measuring section is in the shape of a truncated cone, and the outer diameter of the measuring section is tapered in a direction away from the holding section, and the diameter of the bottom surface of the measuring section facing away from the holding section is 4mm The diameter of the end face connecting the measuring section with the holding section is 6mm, and the length of the measuring section is 9.6mm; the outer wall of the measuring section is provided with a scale, and the scale of the scale is perpendicular to the measured section The axis direction of the scale is arranged in parallel, and the scale unit length of the scale scale is 0.8mm; the holding section is cylindrical, and th...

Embodiment 2

[0036] An application of an appliance for modeling pig knee articular cartilage defect in the field of pig knee articular cartilage defect modeling, the method is: hammer the measuring section of the appliance into the pig knee articular cartilage to be modeled, pass the scale The ruler controls the hammering depth for sampling modeling.

[0037] The utensil of the pig knee articular cartilage defect modeling provided by the custom-made processing provided by the embodiment of the present invention is used to model the Wuzhishan pig knee articular cartilage defect as follows Figure 4 4A shows that the depth of the model is 0.8mm; 4B shows the defect with a diameter of 6mm and a diameter of 4mm, of which the 4mm defect is above the calcification layer, that is, 0.8mm deep, and the 6mm defect is already in the calcification layer; 4C It shows that the 6mm defect has passed through the calcification layer, while the 4mm defect has reached the subchondral bone, with a depth of 1....

Abstract

The invention is applicable to the field of biomedicines and provides an appliance for molding of pig knee-joint cartilage coloboma and application thereof. The appliance for molding of the pig knee-joint cartilage coloboma comprises a main body arranged in a tubular mode, wherein the main body comprises a handheld section for holding and a measurement section for measurement, and the handheld section and the measurement section are connected mutually. The measurement section is in a shape of a circular truncated cone, the outer diameter of the measurement section is gradually decreased in the direction deviating from the handheld section, a graduated scale for measuring the depth is arranged on the outer wall of the measurement section, and scales of the graduated scale are parallelly arranged in the axis direction perpendicular to the measurement section.

Description

technical field [0001] The invention belongs to the field of biomedicine, and in particular relates to an appliance for modeling pig knee articular cartilage defects and its application. Background technique [0002] Articular cartilage defect is a common disease, often caused by sports injuries, and occurs in young people who exercise a lot. Traditional surgical treatment has not been able to achieve hyaline cartilage repair, and the advent of tissue engineered cartilage provides a new idea for repairing articular cartilage defects. The application of tissue engineering technology in the regeneration and repair of articular cartilage defects has become a research hotspot in the treatment of cartilage defects. [0003] Preclinical research on tissue engineered cartilage products relies on animal experiments. At present, rabbits and mice are commonly used animal models for cartilage defects, and there are many methods for preparing animal models of cartilage defects, includi...
