Percutaneous lung puncture model and manufacturing method thereof

Abstract

The invention discloses a percutaneous lung puncture model and a manufacturing method thereof. The model comprises a lung tissue model, a skeleton model and a skin tissue model. The lung tissue modelis wrapped in a skeleton, the skin tissue model covers the skeleton model, pathological modules are distributed in the lung tissue model, the pathological modules are tightly combined with lung tissues, an obvious interface is formed between the pathological modules and the lung tissue model, and the pathological modules and the lung tissue model present different colors. The percutaneous lung puncture model provided by the invention can simulate the structural characteristics of human body lung tissues and internal pathological tissues, sizes and spatial positions of pathological tissues aresimulated, lung tissues and internal pathological tissues can present an image comparison difference characteristic similar to human body real normal tissues and pathological tissue structures under imaging equipment, the model is used for simulating a puncture operation guided by imaging equipment in a real operation, so that the operation effect of a trainee in the operation is evaluated or theoperation process of a puncture needle and other medical instruments in the operation is visually displayed.

Description

technical field [0001] The invention relates to a percutaneous lung puncture model and a manufacturing method thereof, belonging to the field of medical model manufacturing. Background technique [0002] Under the guidance of X-ray, ultrasound, CT and other imaging methods, percutaneous lung puncture is used to puncture the lesion with a fine needle, extract part of the cell tissue or inject slow-release chemotherapy drugs or radioactive particles for the diagnosis or treatment of the lesion. Percutaneous lung puncture is very common in clinical practice, and it has high requirements for doctors to operate. It is necessary to complete the whole process quickly and accurately, and shorten the time as much as possible. Therefore, it is of great significance to provide an effective percutaneous lung puncture model for the training of doctors' skills and the demonstration of surgical instruments. [0003] Currently, there is no lung puncture model that meets the above condition...

AI Technical Summary

Problems solved by technology

Some puncture models based on rubber and silica gel can only realize the simulation of the shape and structure and realize the insertion and withdrawal of fine needles, but they cannot simulate the puncture texture close to human tissue, let alone the development of pathological tissue under imaging equipment, so they cannot be used Practice of percutaneous lung puncture under the guidance of X-ray, ultrasound, CT and other imaging methods
