Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of teaching instrument, concretely relates to a vertebral body shaping operation teaching and practicing model. BACKGROUND
[0002] Percutaneous vertebroplasty is a minimally invasive technique that strengthens the vertebral body by injecting bone cement or artificial bone into the diseased vertebral body. It is mainly used for: senile osteoporotic vertebral compression fractures, intravertebral hemangioma, lymphoma, tumors and metastatic tumors; the purpose of percutaneous vertebroplasty is to increase the stability of the spine by restoring the height of the vertebral body and increasing the strength of the vertebral body, and after the strength of the vertebral body is restored, it can prevent the vertebral body from further collapsing and deforming. Its analgesic principle is: through the coagulation and adhesion of bone cement, it can stabilize the fracture in the vertebral body and avoid the pain caused by the micro-motion of the fracture, providing a stable environment for the healing of the fracture; in addition, the monomer of bone cement has cytotoxicity, and the heat generated during polymerization and other factors can cause tumor necrosis and destruction of sensory nerve endings, thereby achieving analgesic effect.

The sleeve is inserted into the first insertion hole, and the supporting device is transmitted into the filling space through the sleeve, so as to support the filling space, simulate the cavity for filling bone cement in the vertebral body shaping, and then the three joints are connected due to the setting of the movable connection, so that the vertebral body model can show the change process of the vertebral body after the filling space is supported, so that students can more intuitively understand the whole process of the operation. The setting of the bellows can be deformed and filled and supported under the premise of ensuring the strength of the joint. The flexible connection layer is used to cooperate with the deformation of the vertebral joint and facilitate the joint connection.
[0009] Further, the vertebral body model is made of transparent material.
[0010] The vertebral body model made of transparent material is more helpful for students to observe the operation process intuitively.
[0011] Further, a plurality of green lamp beads are arranged on the inner wall of the first insertion hole, and a plurality of red lamp beads are arranged in the second insertion hole and the third insertion hole.
[0012] The green lamp beads are used to display the correct insertion path, and the red lamp beads are used to display the wrong insertion path.
[0013] Further, the vertebral body model is vertically symmetrical and divided into two parts, the two parts of the vertebral body model are detachably connected, and the contact connection parts are respectively provided with a clamping hole and a clamping plate. The clamping plate is inserted into the clamping hole to realize the clamping connection.
[0014] The symmetrical and divided vertebral body model is mainly used to detach the vertebral body model, so that students can more intuitively understand the internal structure.
[0015] Further, the supporting device comprises an inflation tube and an air bag, one end of the inflation tube is connected with the air bag, and the other end of the inflation tube is connected with an inflation device.
[0016] The inflation device generates air pressure, and the air bag is inflated through the inflation tube, so as to support the filling space through the air bag.
[0017] Further, the flexible connection layer is filled with cotton.
[0018] The setting of the cotton ensures its softness and also ensures its supporting property.
[0019] Beneficial effects: During teaching, the utility model can make students understand the wrong insertion position and the serious consequences caused by the setting of the second insertion hole and the third insertion hole, so that students can avoid making mistakes in future practice. The sleeve is inserted into the first insertion hole, and the supporting device is transmitted to the filling space through the sleeve, so as to support the filling space, imitating the development of the cavity for filling bone cement in vertebroplasty. Afterwards, due to the setting of the movable connection of the three joints, the vertebral model can show the change process of the vertebral body after the filling space is supported, so that students can understand the whole surgical process more intuitively. The setting of the bellows can be deformed and filled and supported while ensuring the strength of the joint. The flexible connection layer is used to cooperate with the deformation of the vertebral joint and facilitate the joint connection. BRIEF DESCRIPTION OF THE DRAWINGS
