Teaching model for tibial tuberosity bone traction operation

Abstract

According to the technical scheme, the teaching model is characterized in that the teaching model comprises a simulated femur, a simulated tibia and simulated skin and flesh wrapping the outer side of the simulated femur and the outer side of the simulated tibia, and through holes penetrating through the two sides are formed in the tuberosity bone position of the simulated tibia; an embedded part for a bone nail to penetrate through is arranged in the through hole, is used for simulating a human skeleton and is made of a material with the hardness similar to that of the skeleton, and the outer diameter of the embedded part is larger than that of the bone nail; the simulated skin and flesh comprises thighbone skin and flesh fixed on the simulated thighbone, tibia skin and flesh fixed on the simulated tibia, and detachable skin and flesh detachably and fixedly connected between the thighbone skin and flesh and tibia skin and flesh, and the detachable skin and flesh are correspondingly arranged at the tuberosity of the simulated tibia and can completely cover the embedded part. The whole treatment process can be continuously familiar through continuous practice and simulation operation on the human body model during learning, and a real patient can conveniently master a correct operation process.

Description

technical field [0001] The invention relates to the field of bone traction teaching equipment, more specifically, it relates to a teaching model for tibial tuberosity bone traction operation. Background technique [0002] With the continuous development of medical technology, medical technology is mainly through continuous practice and model operation. When medical students are studying, they will actually operate the human body model to familiarize themselves with the entire treatment process. Femoral fracture is a common disease in orthopedics. It is often necessary to perform traction and immobilization on patients before surgery, and some patients even need long-term traction treatment due to their own factors. Correct traction operation of tibial tuberosity, selection of appropriate traction angle and traction weight are very important for fracture reduction. To master the correct operation process before operating on real patients, it is necessary to carry out repeate...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned bone traction is a means that an orthopedic surgeon must be proficient in. Therefore, it is necessary to simulate the bone traction in the medical teaching process. However, there is no special teaching model for the clinical teaching of tibial tubercle bone traction. There are some deficiencies in traditional orthopedic medical teaching aids. For example, the general-purpose mannequin is made of hard plastic, and it is impossible to place distraction bone screws. Therefore, when students are studying this model, the teacher can only do it on the general-purpose mannequin. Stroke-style teaching, students cannot deeply understand the correct needle entry and exit points of the operation, so that students cannot truly understand the operation process

Some general-purpose mannequins may be made of silicone material. Even if traction bone screws can be placed, it will cause permanent damage to the model, and the model cannot be used repeatedly. At the same time, the feel of the nails made of silicone is completely different from that of human bones, and cannot be maximized. Simulated human operation process

The general-purpose human body model does not simulate the appearance of the knee joint and tibial tubercle in place, and students cannot accurately locate the needle insertion point on the body surface, so that they have no way to start when operating on the patient
